With climate change, the oceans are becoming more acid and that is a threat to the dungeness crab, according to a study by the US National Oceanic and Atmospheric Administration.
The study says ocean acidification expected to accompany climate change may slow development and reduce survival of the larval stages of Dungeness crab.
The dungeness crab is a key component of the Northwest marine ecosystem and vital to fishery revenue from Oregon to Alaska.
The research by NOAA Fisheries’ Northwest Fisheries Science Center in Seattle indicates that the declining pH anticipated in Puget Sound could jeopardize populations of Dungeness crab and put the fishery at risk. The study was recently published in the journal Marine Biology.
Ocean acidification occurs as the ocean absorbs carbon dioxide from the combustion of fossil fuels. Average ocean surface pH is expected to drop to about 7.8 off the West Coast by 2050, and could drop further during coastal upwelling periods.

Dungeness crab is the highest revenue fishery in Washington and Oregon, and the second most valuable in California, although the fishery was recently closed in some areas because of a harmful algal bloom. The Dungeness crab harvest in 2014 was worth more than $80 million in Washington, $48 million in Oregon and nearly $67 million in California
“I have great faith in the resiliency of nature, but I am concerned,” said Jason Miller, lead author of the research, which was part of his dissertation. “Crab larvae in our research were three times more likely to die when exposed to a pH that can already be found in Puget Sound, our own back yard, today.”
Scientists collected eggs from Dungeness crabs in Puget Sound and placed them in tanks at the NWFSC’s Montlake Research Laboratory. The tanks held seawater with a range of pH levels reflecting current conditions as well as the lower pH occasionally encountered in Puget Sound when deep water wells up near the surface. Larvae also went into tanks with the even lower-pH conditions expected with ocean acidification.
“The question was whether the lower pH we can expect to see in Puget Sound interferes with development of the next generation of Dungeness crab,” said Paul McElhany, a NOAA Fisheries research scientist and senior author of the paper. “Clearly the answer is yes. Now the question is, how does that play out in terms of affecting their life cycle and populations overall?”
Larvae hatched at the same rate regardless of pH, but those at lower pH took longer to hatch and progressed through their larval stages more slowly. Scientists suggested that the lower pH may reduce the metabolic rate of embryos. That could extend their vulnerable larval period, or could jeopardize the timing of their development in relation to key food sources, researchers suggested.
Larval survival also dropped by more than half at lower pH. At pH 8.0, roughly equivalent to seawater today, 58 percent of the crab larvae – called zoeae – survived for 45 days. At pH 7.5, which sometimes occurs in Puget Sound now, survival was 14 percent. At pH 7.1, which is expected to roughly approximate the pH of water upwelling on the West Coast with ocean acidification, zoeae survival remained low at 21 percent.
“Areas of greatest vulnerability will likely be where deep waters, naturally low in pH, meet acidified surface waters,” such as areas of coastal upwelling along the West Coast and in estuary environments such Hood Canal, the new study predicts.
Eel grass is not a seaweed but a flowering plant that migrated to the sea, say scientists who have now mapped the eel grass genome. The study also shows that eel grass ( Zostera marina) is crucial in absorbing carbon dioxide in the soft sediments of the coasts.
Eel grasses form a carbon dioxide sink: “they store more carbon than tropical forests,” says Jeanine Olsen of the University of Groningen in the Netherlands who led the study.
Coastal sea grass ecosystems cover some 200,000 square kilometers, the study says. Those ecosystems account for an estimated 15 per cent of carbon fixed in global ocean, and also impact sulphur and nitrogen cycles.
The scientists argue that since sea grasses are the only flowering plants to have returned to the sea that is the most extreme adaptation a terrestrial (or even freshwater) species can undergo.
The science team says the Zostera marina genome is “an exceptional resource that supports a wide range of research themes, from the adaptation of marine ecosystems under climate warming and its role in carbon burial to unraveling the mechanisms of salinity tolerance that may further inform the assisted breeding of crop plants.”

Sea grasses form the backbone of one of the most productive and biodiverse ecosystems on Earth, rivaling coral reefs and rain forests in terms of the ecosystem services they provide to humans.
Sea grass meadows are part of the soft-sediment coastal ecosystems found in all continents, with the exception of Antarctica. They not only form a nursery for young fish and other organisms, but also protect the coastline from erosion and maintain water clarity. ‘
The study, which sequenced the genome of the eel grass taken from the Archipelago Sea off Finland. published today, in the journal Nature, is the work of an international consortium of 35 labs, most of them in Europe, working with researchers from the U.S. Department of Energy Joint Genome Institute.
The study showed that eel grasses are completely submerged marine flowering plants, called by science angiosperms. It shows that eel grass is a member of the ancient monocot family.
The monocots include about 60,000 species, flowering plants that first appear above the soil as a single leaf. They include orchids, “true grasses,” as well as rice, wheat, maize and “forage grasses” such as sugar cane, and the bamboos. According to Wikipedia, other economically important monocot crops include palms bananas , gingers, onions, garlic, lilies, daffodils, irises, amaryllis, bluebells and tulips.
Zostera marina is the first marine flowering plant have its genome fully sequenced. As well as finding the eel grass’s genetic ancestors the researchers were interested in understanding how the plant–and by extension other plants in the ecosystem–adapt to climate change.
As it adapted to an underwater, coastal lifestyle, eel grass gained genes that allowed it to live in saltwater but lost genes involved in traits associated with land-based plants.
Olsen called this “arguably the most extreme adaptation a terrestrial (and even a freshwater) species can undergo.”
What she describes as the “use it, lose it, or change it” scenario, eelgrass modified its cell walls. The eel grass cell wall is very different from normal plant cell walls and more like that of sea algae, similar to the cell in seaweeds. The eel grass has lost genes associated with light-sensing, pollination and regulation of internal water balance.
Eel grass lost its stomata (which are used by land plants to ‘breathe’) but also all of the genes involved in stomatal differentiation. “The genes have just gone, so there’s no way back to land for sea grass,” Olsen says. Sex is entirely underwater involving long naked sperm filaments especially adapted for underwater fertilization of the tiny flowers.
The team compared the eel grass genome to duck weed, one of the simplest flowering plants and Zostera marina’s closest sequenced relative. They noted differences in genes related to cell wall structure due to adaptations to freshwater or terrestrial conditions. For example, plants such as duckweed have seemingly lost genes that help plants retain water in the cell wall, while eel grass has regained these genes to better deal with osmotic stress at low tide.
“They have re-engineered themselves,” said Olsen of the changes affecting the eelgrass cell walls. “Crop breeders may benefit from lessons on how salt tolerance has evolved in these plants.”

With Zostera marina meadows stretching from Alaska to Baja California, and from the White Sea to southern Portugal, Olsen noted that these ecosystems afford researchers “a natural experiment to investigate rapid adaptation to warmer or colder waters, as well as to salinity tolerance, ocean acidification and light.”
Eel grass endangered
Jeremy Schmutz, head of the US Department of Energy’s genetic plant program, emphasized that while eel grasses are key players in coastal marine ecosystem functions and considered the “lungs of the sea,” they are also endangered. “There are estimates that nearly a third of the eel grass meadows worldwide have been destroyed by runoff into the ocean,” he said, “reducing their potential capabilities as carbon sinks. Thus, studying the adaptive capacity of eel grass is urgent to assist conservation efforts.”
An overarching question for Olsen’s team is how quickly eel grass can adapt to rapid climate change. The fact that Zostera marina grows along the coastline from Portugal to Scandinavia is being used as a natural experiment to investigate adaptation to warmer or colder water, as well as to salinity, ocean acidification and light.
That’s one of the predictions from a new study from the University of British Columbia, looking at the future of the fishery on the coast.
The study concentrates on the First Nations fishery and warns that aboriginal people could face a catastrophic decline in the harvest of traditional species, especially salmon and herring roe on kelp over the next thirty years, a decline that will also have an equally devastating effect on commercial and recreational fishing.
The main cause of the decline is climate change and the warming of the coastal waters. The study projected “modest to severe declines in catch potential” for all current commercial fisheries along the coast.
The study says that for the First Nations the between $28 million to $36 million in revenue they got from fishing between 2001 and 2010 could fall by up to 90 per cent depending on how the climate changes.
A chart from the UBC study shows possible decline in fish species under different climate scenarios. (PLOS1)
One scenario calls for a decline of up to 40 per cent in chinook and pink salmon.
If there is any good news, if you can call it that, the decline will be not as bad in northern coastal waters as it will be the warmer waters near the Lower Mainland and southern Vancouver Island. The range of some species, including salmon, herring, halibut and possibly oolichan will move to farther north along the BC Coast and into Alaskan waters.
That means in time the warming waters will also encourage an increase in other species, including sardines and some clams.
The changing oceans mean that “an increase in the relative abundance of warmer-water species was projected to lead to new or increased opportunities for commercial harvests by 2050.”
The study is urging the First Nations and other stakeholders in the British Columbia fishery to start long term planning immediately to anticipate changes in the coming decades.
The team of scientists led by Lauren Weatherdon, a graduate student at UBC, noted that while previous studies have looked at the impact of climate change on large-scale commercial fisheries, “few efforts have been made to quantitatively project impacts on small-scale subsistence and commercial fisheries that are economically, socially and culturally important to many coastal communities.”
The study was conducted in cooperation with the BC First Nations Fisheries Council and looked its seven coastal administrative regions “forming a sample of groups with diverse marine resources, geographical locations, territorial sizes, and treaty statuses.”
Within those regions 16 First Nations participated in the study, some under their treaty councils, including the Council of the Haida Nation, the Tsimshian Nations Treaty Society (including the Gitga’at at Hartley Bay and the Kitselas and Kitsumkalum near Terrace) and the Maa-nulth First Nations. The Heiltsuk First Nation at Bella Bella participated as an independent group.
The FNFC’s administrative regions intersect with five distinct ecological regions: the North Coast, comprising the Hecate Strait and Dixon Entrance; Haida Gwaii, which includes the waters surrounding the islands; the Central Coast, including Queen Charlotte Sound, Queen Charlotte Strait, and the southern tip of Hecate Strait; the Strait of Georgia; and the west coast of Vancouver Island (WCVI) .
The study says First Nations are likely to be exposed to different climate-related impacts on fisheries due to the differing ecological and biogeographical characteristics of these regions and to differing traditional and commercial harvests.
The study used a “dynamic bioclimate envelope” computer model to look at the changes to the distribution and relative abundances of the BC coastal species under two climate change scenarios, a high greenhouse gas model where society can’t curb emissions and a low greenhouse gas emission scenarios, depending on how society is able to curb the increase.
The study looked at ocean properties—including sea surface temperature, sea bottom temperature, salinity, oxygen concentration, surface action, and net primary production—using data from the US National Ocean and Atmospheric Administrations’ climate-related earth system model.
Climate change will mean that current species on the BC coast will “shift polewards.”
The study showed that by 2050, there could be declines in 87 of the 98 species in the study.
Greater losses in what the study calls “species richness” is likely to occur towards the southern coast of British Columbia, falling primarily between 48°N and 51°N. But, overall, species richness along coastal BC will continue—only with different species.
Most significantly the study projects a decline in the overall salmon catch from 17.1 per cent to 29.2 per cent, depending on the region and climate.
All aspects of the herring fishery, including roe herring, spawn-on-kelp, and the food and bait fishery could decline between 28.1 per cent and 49.2 per cent depending on the region.
The future of the oolichan is the most uncertain. One of the models studied projected a further 37.1 per cent decline in the oolichan, while other models called for for a decline between 5 per cent and 6.8 per cent. That will depend on how well, the oolichan already threatened in most regions of British Columbia are able to adapt to warmer waters or find a way to move their range northward.
The study says white sturgeon and Pacific sardines were projected to increase in abundance under both climate change scenarios, while manila clams were projected to increase in abundance by 14.5 per cent in one of the models. The eight remaining species showed little change.
The study suggests that the southern territories (Tsawwassen, Tla’amin, and Maa-nulth First Nations) will likely see a reduction in catch potential between -15.2 per cent and -27.8 per cent depending on how the climate changes.
On the north coast. The Haida and Tsimshian First Nations and those situated along the central or north-eastern coasts of Vancouver Island (Heiltsuk and ‘Namgis First Nations) would likely see smaller reductions in relative catch for each territory, with estimates falling between -3.2 per cent and -8.2 per cent.
The study shows that for the First Nations along the North and Central Coasts of British Columbia (Gitga’at and Haida, and Heiltsuk and ‘Namgis) there will be neutral or positive shifts in catch potential for white sturgeon, kelp greenling, and two species of perch under both scenarios.
While varying regionally, both scenarios also suggested either a slight cumulative decline or negligible change in catch potential for clams, rockfish, lingcod, and sculpins across the North and Central Coast.
One potential problem the study suggests is that fishers in southern British Columbia may, in the future, try to move north to follow the harvest, leading to potential conflicts. The cost of travel, may, however, discourage that.
One of the recommendations from the study is that First Nations revive the traditional clam gardens.
Traditional clam beds serve as an ideal example of a method that could be applied to offset climatic impacts through internalized mechanisms, using local cultivation to generate increased productivity by enhancing native habitat rather than redirecting extraction efforts towards other regions or species. Clam gardens constructed in a manner akin to those situated near ancient settlements of the Northern Coast Salish and Laich-kwil-tach First Nations have been found to generate higher clam densities, biomass, and growth rates than non-walled beaches . These benefits were observed for Pacific littleneck clams and butter clams , two clams that are of cultural, economic, and ecological importance to the region Reinstating clam beds in First Nations’ territorial lands has been suggested as a means of simultaneously achieving local conservation and cultural objectives and may thereby provide a politically and ecologically viable option for mitigating climate-related impacts.
The most important recommendation is that the First Nations and other stakeholders start cooperating immediately to offset how the changing climate with affect the fishery:
Management of salmon and herring stocks has been highly contentious due to the myriad of stakeholders who depend upon them, which include First Nations, recreational fisheries, and commercial fisheries….
Aside from fulfilling societal needs, salmon serve as key ecological components of the Pacific Northwest Coast, functioning as the mechanisms by which nutrients are transferred from the ocean to freshwater and terrestrial ecosystems
It says the projections show that a “redistribution of fishing effort” will not “fully offset declines in salmon and herring”
attaining a state of collaboration between First Nations, DFO, and other sectors has the potential to yield beneficial ecological and political results, if implemented correctly. Parallels exist between First Nations’ traditional fisheries management approaches and “modern” approaches (e.g., spatial management, mariculture, selective fishing, fishing closures), with differences arising primarily due to diverging worldviews.
It recommends local application of First Nations’ traditional management strategies to “provide opportunities to collaboratively engage in adaptive ecosystem-based management and to coordinate efforts to attain conservation objectives.”
They give an example of how the Nisga’a Nation have ensured their equal partnership in management by employing traditional fish wheel technology to monitor and assess stocks and by leveraging traditional ecosystem-based management practices that could be applied to plan long-term objectives and management approaches.
It concludes by saying that joint-management will not only work to reduce the impact of climate change but also head off potential conflict.
Through such joint-management regimes, traditional fisheries management strategies could be applied to advance localized research directives and to reduce impacts on stocks under unprecedented environmental change. Moreover, the risk of conflict over declining resources underlines the need to establish common and equitable ground to ensure successful joint management of fisheries, and to leverage collective expertise.

“Very low levels” of crude oil from the 1989 Exxon Valdez spill in Prince William Sound, Alaska, are a threat to the survival of herring and pink salmon that spawn in the region, according to a study released today by the US National Oceanic and Atmospheric Administration.
The study shows that embryonic salmon and herring exposed to very low levels of crude oil can develop hidden heart defects that compromise their later survival.
That means that the Exxon Valdez spill on March 24, 1989 may have had much greater impacts on spawning fish than previously recognized, according to the study published in Nature’s online journal Scientific ReportsVery low embyronic crude oil exposures cause lasting defects in salmon and herring.
“These juvenile fish on the outside look completely normal, but their hearts are not functioning properly and that translates directly into reduced swimming ability and reduced survival,” said John Incardona, a research toxicologist at NOAA Fisheries’ Northwest Fisheries Science Center (NWFSC) in Seattle. “In terms of impacts to shore-spawning fish, the oil spill likely had a much bigger footprint than anyone realized.”
This is a juvenile pink salmon exposed to low levels of crude oil as an embryo. While these fish appear outwardly normal, they nevertheless developed heart defects that compromised their ability to swim. Fish that are less able to forage and avoid predators are much less likely to survive to adulthood. (NOAA)
Previous research has shown that crude oil disrupts the contraction of the fish heart muscle cells. Embryonic fish exposed to trace levels of crude oil grow into juveniles with abnormal hearts and reduced cardiorespiratory function.
“With this very early impact on the heart, you end up with an animal that just can’t pump blood through its body as well, which means it can’t swim as well to capture food, form schools, or migrate,” said Mark Carls, toxicologist at the Alaska Fisheries Science Center. “Crude oil is changing basic physiology, or what makes a fish a fish.”
The research builds on earlier work by the Auke Bay Laboratories, part of NOAA Fisheries’ Alaska Fisheries Science Center, which found much reduced survival of pink salmon exposed as embryos to polycyclic aromatic hydrocarbons (PAH) from crude oil.
“Our findings are changing the picture in terms of assessing the risk and the potential impacts of oil spills,” said Nat Scholz, leader of the NWFSC’s ecotoxicology program and a coauthor of the new study. “We now know the developing fish heart is exquisitely sensitive to crude oil toxicity, and that subtle changes in heart formation can have delayed but important consequences for first-year survival, which in turn determines the long-term abundance of wild fish populations.”

The Exxon Valdez spill was the largest in U.S. history, with extensive oiling of shoreline spawning habitats for Pacific herring and pink salmon, the two most important commercial fish species in Prince William Sound.
Herring larvae sampled in proximity to oil were visibly abnormal, and mortality rates were higher for pink salmon embryos at oil spill sites than unaffected regions.
The herring fishery collapsed three to four years after the spill, when the herring spawned in oiled areas reached reproductive maturity.
The paper notes that the contribution of the spill to the herring population collapse, if any, was never determined and remains controversial.
Other studies, however, tend to confirm the findings, including heart problems for fish exposed to the Gulf of Mexico Deepwater Horizon spill and even fish exposed to naturally occurring oil seeps.
The new findings suggest that the delayed effects of the spill may have been important contributors to the declines.

Scientists from the Northwest Fisheries Science Center and Alaska Fisheries Science Center temporarily exposed embryonic salmon and herring to low levels of crude oil from the North Slope of Alaska and found that both absorbed chemicals at similar concentrations in their tissues. The embryos were then transferred to clean seawater and raised as juvenile fish for seven to eight months.
Few of the exposed embryos were outwardly abnormal in any way. However, closer examination of the fish revealed subtle defects that could reduce their long-term survival.
Juvenile salmon exposed to oil grew more slowly, with those exposed to the highest concentrations growing the slowest. For salmon, early survival in the ocean is strongly influenced by juvenile growth, with smaller fish suffering higher loss to predators.
Scientists used swimming speed as a measure of cardiorespiratory performance and found that fish exposed to the highest concentrations of oil swam the slowest. Slower swimming is an indication of reduced aerobic capacity and cardiac output, and likely makes fish easier targets for predators.
Exposure to oil as embryos altered the structural development of the hearts of juvenile fish, potentially reducing their fitness and swimming ability. Poor swimming and cardiac fitness is also a factor in disease resistance.
Earlier studies on the ecosystem-scale crash of the Prince William Sound herring population several years after the Exxon Valdez spill were based on higher levels of exposure to the oil. The new study shows that that cardiac injury occurs in normal-appearing fish that survive even lower level exposures.
The scientists reviewed data on measured oil concentrations in surface water samples collected in Prince William Sound after the oil spill and during the 1989 herring spawning season. Most of the 233 samples contained less oil than was believed to be toxic to herring at the time, based on visible gross developmental abnormalities. However, nearly all of the samples contained oil at or above concentrations shown in the new study to alter heart development.
If the Exxon Valdez spill impacted heart development among a large majority of fish that were spawned in proximity to oiled shorelines, the subsequent losses of juveniles to delayed mortality would have left fewer adults to join the population. Although not direct proof, this provides a plausible explanation for the collapse of the Prince William Sound herring stock four years later, when fish spawned during the oil spill would have matured.
The study concludes that the impacts of the Exxon Valdez spill on near shore spawning populations of fish are likely to have been considerably underestimated in terms of both the geographic extent of affected habitat and the lingering toxicity of low levels of oil. The findings will likely contribute to more accurate assessments of the impacts of future oil spills, Incardona said. “Now we have a much better idea of what we should be looking for,” he said.
That means, according to the study “that the impacts of the Exxon Valdez oil spill on populations of near shore spawning fish are likely to have been considerably underestimated, in term of both the geographic extent of affected habitats and the lingering toxicity of low levels of residual oil.”
The report calls for more studies of the sensitivity of the developing fish heart since the vulnerability “also has implications for other pollution sources in marine ecosystems, including increasing maritime vessel traffic and expanding land-based urban runoff.”
Scientific studies after the Exxon Valdez spill indicated that the vast majority of species recovered following the spill and that functioning ecosystems, similar to those existing pre-spill, were established.
Species for which recovery is not fully apparent, such as Pacific herring, killer whales, and pigeon guillemots, appear to have been affected by other environmental factors or human influences not associated with the oil spill. Insufficient pre-spill baseline data on these species contributed to difficulties in determining the extent of spill effects.
Based on the evidence, the Panel finds that natural recovery of the aquatic environment after an oil spill is likely to be the primary recovery mechanism, particularly for marine spills. Both freshwater and marine ecosystem recovery is further mitigated where cleanup is possible, effective, and beneficial to the environment.
Natural processes that degrade oil would begin immediately following a spill. Although residual oil could remain buried in sediments for years, the Panel finds that toxicity associated with that oil would decline over time and would not cause widespread, long-term impacts.
Diluted bitumen, also known as dilbit, a mixture of oil sands bitumen and natural gas dilutants can seriously harm fish populations, according to research study at Queen’s University and the Royal Military College of Canada published this week.
At toxic concentrations, effects of dilbit on exposed fish included deformities and clear signs of genetic and physiological stress at hatch, plus abnormal or uninflated swim bladders, an internal gas-filled organ that allows fish to control their buoyancy. Exposure to dilbit reduces their rate of survival by impairing their ability to feed and to avoid predators.

Among the other findings from the study were
Embryo toxicity of dilbit was comparable to that of conventional oils.
Developmental malformations increased with increasing dilbit concentrations.
Chemical dispersion broadened the genotoxic effects of dilbit
“This new study provides a clearer perspective on the potential risks to Canada’s aquatic resources of dilbit spills, and a technical basis for decisions on dilbit transportation within Canada,” says Peter Hodson Environment Studies, Biology at Queens. “It reduces some of the uncertainty and unknowns about the hazards of dilbit.”
This study characterized the toxicity and physiological effects of unweathered diluted bitumen (Access Western Blend dilbit; AWB) to a fish used for laboratory studies. Embryos of Japanese medaka (Oryzias latipes) were exposed for 17 days to dilutions of dilbit physically-dispersed by water and chemically-dispersed by dispersants
AWB dilbit exposure was not lethal to medaka, but resulted in a high prevalence of blue sac disease (BSD), impaired development, and abnormal or un-inflated swim bladders. Blue sac is a disease of young trout and other salmonid species; usually caused by unsuitable hatchery water. It turns the yolk sac bluish and is thought to be caused by a lack of oxygen.
The research was funded by Fisheries and Oceans Canada’s National Contaminants Advisory Group and the next stage will determine whether fish species native to Canada will be affected by dilbit exposure. The work also includes the development of genetic markers of exposure to dilbit and toxicity that could be used to assess whether wild fish that survive a spill are still affected.
The research team includes Dr. Valérie Langlois (Environmental Studies, Royal Military College of Canada) and Dr. Barry Madison (Royal Military College of Canada).
Dr. Hodson is also a member of a Queen’s research team tasked to determine whether dilbit spilled into rivers would contaminate bed sediments, specifically areas where fish such as salmon, trout, chars, whitefish and graylings spawn, to the extent that the survival of their embryos would be affected.
The research was published in ScienceDirect and is one of the first studies of dilbit on young fish.
The finding could be significant because both the proposed Northern Gateway pipeline and the proposed Kinder Morgan expansion will cross areas near spawning streams.
Haisla Nation Chief Counsellor spoke at Mt. Elizabeth Theatre on June 9, 2015, introducing David Suzuki who was on a speaking tour. This is a lightly edited report on his remarks that outline some of the dilemmas facing the Haisla and the Kitimat valley in an age that needs development but faces climate change.
Good evening.
Among chiefs, I am elected, not hereditary, you are born into that position, I wasn’t born into it.
I am basically a regular commoner just like you guys with a high school education and one year of college and a lot of experience outside my community that I bring back.
These topics about climate change locally, provincially, nationally and worldwide, they’re complicated topics.
Haisla Chief Counsellor Ellis Ross speaks at Mt. Elizabeth Theatre, June 9, 2015 (Robin Rowland/Northwest Coast Energy News)
There’s no one true fix for all of it. The problem is that the Haisla have been thrust into the middle of it and we have to answer it, which is very unfair.
So when we’re talking about what really is a Haisla value, a west coast, a British Columbia value. I must tell you I value the Haisla people, my people, that land, the territory, I think about the Haisla people because I don’t think anyone has given the Haisla people a priority in the last 40 to 50 years.
All the decisions that were made about Haisla territory, that affected out people, were made without us.
The result was that we ended up with 80 per cent unemployment, historically over the last 40 years we have ended up with cancer and we can’t get rid of it.
Poverty, people couldn’t get enough money to fix their bathrooms when the floor was rotting out.
The saying is that you can always tell when the reserve starts is when the pavement ends is true. Unless there’s a political agenda to actually pave the road to the village. The environmental questions that have been raised over the past ten years are not new to the Haisla.
In the 70s it was the Haisla alone who tried to battle emissions when nobody even knew what emissions meant. They tried to stop the effluent dumping into the river that killed off the river they tried to stop the diking of the river so parts of the land could be protected, parks.
When the Haisla knew that the oolichan that was estimated to be hundreds of thousands of tons, were dying off quickly in the span of five years. Nobody listened.
Now the DFO and Canada is realizing that the demise of the oolichan is a signal that something is wrong with the ecosystem.
I would love that someone would come around to the idea of thanking the Haisla people for all the work that they did and went and unheard even in meetings like this today.
And we’re not even talking about salmon.
In all this time, I’ve read all the documents, all the speeches and listened to all the promises of a better tomorrow for all the people but nobody delivered it.
Countless academic papers have been written about Indian poverty.
Nothing was done.
Non-profit organizations used the Haisla to further their cause and left town when they had achieved what they had achieved.
At the same time all the decisions continued to be made without us. And everybody benefited except us.
What happened in the end and the corporations made their billions and made enough money to pay off the mortgage and move down south, the Haisla were left with the mess to clean up. Today we’re still battling to get some of these sites cleaned up and we’re still not getting help.
I don’t blame anyone for this. Whether you’re am environmental organization, a government or a corporation or a non-profit organization, I don’t blame you for this because you have a mandate, you have a special interest. That’s what you’re trying to achieve.
I have a mandate. I do have an organization now that is fully equipped to look at every single permit that comes from the provincial government and the federal government and try to mitigate it given our capacity and our lack of funding.
But some of that benefit has to flow to the Haisla people. It’s our territory.
When you think about what has happened to us, the Haisla, we think about residential schools and I’ve been reading the debate on whether or not it’s genocide or not and I think people are missing the point.
Residential schools were only 10 per cent of a larger program to get rid of the Indian.
The ninety per cent was what was stolen from us as well. The land was taken away and we were put on a chunk of land across the Channel, that was described by the Indian Agent as worthless, it’s not even good for agriculture so give it to the Indians. We had to get permission from the federal government to leave that reserve. We had to get a piece of paper that said he’s allowed to leave the reserve and go pick berries.
We also have had no help other than some academic programs and some sort of study to deal with our suicides. I’m not just talking Haisla here. I really thought that one suicide every five years was really a bad thing. But finding out that my neighbors down the road from here to Prince George are dealing with ten suicides in the first quarter of this year.
It breaks my heart.
Who is responsible for that? If it’s not the government, if it’s not the non-profits, if it’s not corporations, who is it?
I stepped up and said I’ll take full responsibility for this but that means I have a hard message to deliver and I will deliver it on behalf of the Haisla people.
When it comes to climate change, we are living at a very unfortunate time, because finally we’re accepted at the provincial table, at the federal table, the corporate table.
We’re being included but unfortunately, we have to look at climate change as well. It’s a very tough position to be in when you’ve got a Grade 12 education from 1984 and one year of college education in 1985.
It’s a very tough topic, I can tell you. I’ve been to China, I’ve been to Korea and no matter what you say about the emissions there, Canada and BC have no problems with emissions here until you visit China.
They’re not going to get off crude oil, they’re not going to get off diesel fuel, they’re not going to give up coal because a billion people there want the same standard of living that you have in Canada. And I’m talking about India as well. They want the same standard. They want good houses; they want to own a car. They are not going to stop their thirst for energy.
I don’t have the answers.
I still believe that natural gas is a lot cleaner than coal and even if you put a small dent in it, it’s not enough to get these guys off nuclear power.
And the solar power you’re talking about, they do it for show but that’s not going to meet the energy needs of China. We’re not even talking about India; we’re not even talking about Korea.
You say can you help get China off dirty fuel, but all their pollution keeps getting dumped on South Korea.
I represent 1700 people, how am I going to do that?
We’re being asked to do a near impossible task while I’m trying to dig my people out of poverty. At the same time, when we get this opportunity we’re giving our members very mixed messages, including our young people which is heart breaking for me.
Because we’re telling them get an education, don’t be a burden on society, get a job, but by the way there are no jobs here, there’s no way to get into existing industries so you better go to the oil fields of Alberta to get a job. A lot of our people head over there or to Vancouver.
I’ve been following this debate on climate change for quite a while now, for over six years. I’ve been listening to everybody, I’ve been listening to corporations, being listening to governments, been listening to non-profits, but on behalf of the Haisla Nation Council, I’m here to tell you, that when it comes to the future of the Haisla I have very little patience with this. I don’t want to see another essay about what to do about Indian suicides.
I believe that our people are being sick and tired of being left out and left behind, while everyone else is moving on with their lives. I do want to what’s best for the region I do want to do what’s best for the province and Canada and the world. But I will not do it at the expense of the Haisla people. We’ve been at the dirty end of the tick for the last 40 years. It’s going to stop. Thank you very much and enjoy your evening.

If anyone wanted a snapshot (or for younger folks a selfie) of why the Harper government grounded out at home, never even getting to first base with northwestern British Columbia on Northern Gateway and other resource projects, it can be found in about sixty pages of documents, obtained by Northwest Coast Energy News under the Access to Information Act, documents that outline the planning for former Natural Resources Minister Joe Oliver’s first visit to Terrace in March 2013
The documents reveal the priority for Natural Resources communications staff was mainly finding an appropriate First Nations visual backdrop for Oliver’s speech announcing the appointment of Douglas Eyford as special representative to First Nations, the Harper government’s attempt to smooth relations as it dawned on the government that opposition to Northern Gateway wasn’t just going to disappear.
Despite years of media coverage from both those opposed to and even those who support the Northern Gateway project that highest priority issue was preventing oil spills whether from tankers or pipelines, the Ottawa-based communications planners in Natural Resources Canada were talking about how aboriginal and non-aboriginal communities could respond to oil spills.
For an event that was supposed to engage the First Nations of coastal British Columbia and gain their support for resource projects, all the economic examples are about Alberta First Nations who are working the extraction of bitumen in Alberta, there are no example of how BC First Nations might profit from Northern Gateway (that is if any BC First Nations actually wanted to do so)
When Natural Resources Canada started planning Joe Oliver’s announcement they created what was called a “Message Event Proposal” which even in its title shows how the government and the communications staff think. The message is more important than the event.
Finding a background with a First Nations focus was a high priority for Natural Resources Canada in choosing Northwest Community College in Terrace for an announcement by Minister Joe Oliver on March 19, 2013. (Robin Rowland/Northwest Coast Energy News)
The planning documents from Natural Resources, starting on March 5, 2013, indicate that from the beginning the announcement was being treated as a photo op. Invitations to or participation by “stakeholders” are listed as N/A “not applicable,” which meant that meetings, even private meetings, with representatives of northwestern First Nations and other communities either weren’t considered or the communications staff weren’t informed. (If there were such plans they were not part of the access documents released and as far as Northwest Coast Energy News can find out no meetings took place since Oliver left for Ottawa immediately after the announcement)
The documents show that there were no plans to involve “stakeholders” in Joe Oliver’s announcement.
The Natural Resources communications staff were working on multiple angles in March, as part of what the planning documents call “a suite of events in Vancouver on marine and pipeline safety.”
The first set of those events would eventually take place on March 18, 2013, in Vancouver, and included the announcement, without consulting either Rio Tinto Alcan or the District, that Kitimat’s private port run by Alcan since it was first built would be turned in a federal public port.
That location certainly wasn’t clear at first. The first documents suggested the announcement take place in Vancouver, and then a day later on March 6, the proposed venue, according to the staff, was in either Prince Rupert or Prince George.
According to the internal e-mails, sometime that week what Ottawa bureaucrats call MINO — the minister’s office– decided that the venue should be Terrace. On March 11, e-mails among Natural Resources staff show that the choice had changed to either Terrace or Prince George.
Since the “special representative” whom we now know would be Douglas Eyford, would report directly to Prime Minister Stephen Harper, the political level was involved. MINO took over writing Oliver’s speech and the arrangements were copied to the Privy Council Office, the civil service branch that has overall supervision of the federal bureaucrats and works directly with the Prime Minister. So the speech that the communications branch had drafted for Oliver became “can please turn the one we had done for him into the remarks for the new guy?”
Plan B in Prince George
The choice of Terrace left the Natural Resources Ottawa staff hedging their bets, looking for a “potential plan B” in Prince George. The e-mails indicate that Ottawa asked Natural Resources west coast communications officer for a list of suitable locations in Prince George.
The communications officer replied with three locations at the University of Northern British Columbia “a moving bear totem on campus” the main administration building which the e-mail said “ has a strong First Nations focus,” adding “Environment Canada has done…events there. Strong FN visuals.” The third choice was “a new bio energy facility that looks industrial.”
Backups were The College of New Caledonia trade centre and the Prince George industrial park.

E-mails from the staff on Wednesday, March 14 and Thursday, March 15, showed while they were now aware the event would be in Terrace, and probably at Northwest Community College, there was still a lot of uncertainty. “We haven’t been able to contact them to confirm, but as soon as we do, we will let you know the exact details as well as what is required in terms of logistics.”
Remembering that Natural Resources and Transport Canada were also planning the Vancouver event on Monday, March 18, it appears that even as Oliver arrived on the morning of March 19, the minister’s staff both political and bureaucratic were still scrambling.
On March 19, the NWCC staff on site were complaining that as soon as the Ottawa delegation saw the standard arrangements for an event at the Waap Galts’ap community long house they ordered the NWCC staff to immediately rearrange the room, so that the podium was in front of one wall with what Oliver’s staff thought was a better First Nations painting. That rearranging was still going on when I arrived to cover the announcement.

Even after the furniture was rearranged, the start was delayed as Oliver and his staff disappeared into an upstairs room for a meeting before the news conference began, and Oliver announced Eyford’s appointment.
During the question and answer session with the media during the news conference, the students that had essentially been brought in as props for the photo op and to help promote Northwest Community College’s industrial training program, began to ask questions.

One student asked Oliver if Eyford’s appointment was going to replace “all talks” with First Nations about resource projects. The Natural Resources public relations staff tried to cut off one student, since the national media were waiting on a telephone conference call. To his credit, Oliver did answer the student’s question, saying Eyford’s appointment was not intended to “replace the independent, regulatory review.” He went on to explain the Northern Gateway Joint Review would continue its work and report at the end of 2013.
What was Ottawa thinking? You too, can respond to an oil spill.
If the aim was to engage the First Nations and other residents of northwestern BC, it is clear that the concerns of this region hadn’t reached out Ottawa.
It appears from the planning documents for Joe Oliver’s trip to Terrace, that a main concern of everyone in the northwest, aboriginal and non-aboriginal, opponents and supporters of the Northern Gateway pipeline, preventing oil spills also wasn’t on the government radar, rather it was preparing and responding to oil spills.
Guess who would respond?
As part of the measures to strengthen Canada’s Marine Oil Spill Preparedness and Response Regime, the Government of Canada will strengthen the engagement and involvement of Aboriginal and non-aboriginal communities in preparing for and responding to oil spills.
When it comes to a key section on benefits from the Northern Gateway and other resource projects, there is no mention of benefits to British Columbia; rather it appears all the examples of benefits for aboriginal communities come from Alberta, including $1.3 billion in contract work for oil sands companies not including construction, for the year 2010, and $5 billion since 2001. The Message Event Proposal also cites a joint venture between the Bigstone Cree and Bronco Energy, “the biggest oil sands project every undertaken on First Nations reserve lands.”
Overall the plan was to “Promote Canada’s commitment to achieving its goals under its plan for Responsible Resource Development, including increased consultations with Aboriginal peoples.”
The “media lines’ issued by Natural Resources also outlined the Harper government’s attitude to the Northern Gateway, noting that Eyford’s appointment was independent of the Northern Gateway Joint Review, and went to indicate that the JRP was “conducting a rigorous, extensive, open, science-based assessment.” It adds that “we will continue to rely on the integrity of this process,” again showing how out of touch Natural Resources was (at least in talking points) since by March 2013, there was growing consensus in the northwest that the JRP had lost its credibility.
The media lines also show that the Harper government believed that “Aboriginal consultations are fully integrated into the review process to ensure meaningful consultation occurs,” a position that most First Nations in British Columbia reject, insisting on meaningful consultations between the Crown and the First Nation.
When Eyford presented his report to the Prime Minister in December, 2013, Eyford called for stronger action to engage First Nations opposed to new oil and gas pipelines.
“It’s never too late to engage and do so in a process of good faith negotiations… “This won’t be an easy process. I hope my report is perceived as providing objective and blunt advice to all the parties engaged in this process.’’
The 53 page report contained dozens of recommendations mainly concerned with a more open and principled dialogue with First Nations.
“The development of West Coast energy infrastructure provides an opportunity to forge partnerships and build relationships. There is a strong interest and real opportunity for Canada and aboriginal Canadians to more effectively collaborate to address their respective interests.’’
Editor’s note: On the port issue, an RTA spokesperson noted that talks with the federal government are continuing. He noted that all the Kitimat port facilities are privately owned, by Rio Tinto Alcan or by LNG Canada and there are “multiple stakeholders” involved.
The United States says acidification of the oceans means there is an already growing risk to the northwest coast fishery, including crab and salmon, according to studies released by the National Oceanic and Atmospheric Administration.
As more carbon dioxide is released into the atmosphere and absorbed by the oceans, the water is becoming more acidic and that affects many species, especially shellfish, dissolving the shells.
A NOAA study released today of environmental and economic risks to the Alaska fishery says:
Many of Alaska’s nutritionally and economically valuable marine fisheries are located in waters that are already experiencing ocean acidification, and will see more in the near future…. Communities in southeast and southwest Alaska face the highest risk from ocean acidification because they rely heavily on fisheries that are expected to be most affected by ocean acidification…
An earlier NOAA study, released in April, identified a long term threat to the salmon fishery as small ocean snails called pteropods which are a prime food source for pink salmon are already being affected by the acidification of the ocean.

NOAA says:
The term “ocean acidification” describes the process of ocean water becoming more acidic as a result of absorbing nearly a third of the carbon dioxide released into the atmosphere from human sources. This change in ocean chemistry is affecting marine life, particularly the ability of shellfish, corals and small creatures in the early stages of the food chain to build skeletons or shells.
Today’s NOAA study is the first published research by the Synthesis of Arctic Research (SOAR) program, which is supported by an US inter-agency agreement between NOAA’s Office of Oceanic and Atmospheric Research and the Bureau of Ocean Energy Management (BOEM) Alaska Region.
Des Nobles, President of Local #37 Fish [UFAWU-UNIFOR] told Northwest Coast Energy News that the fisheries union and other fisheries groups in Prince Rupert have asked both the Canadian federal and the BC provincial governments for action on ocean acidification. Nobles says so far those requests have been ignored,
Threat to crabs
The studies show that red king crab and tanner crab grow more slowly and don’t survive as well in more acidic waters. Alaska’s coastal waters are particularly vulnerable to ocean acidification because of cold water that can absorb more carbon dioxide and unique ocean circulation patterns which bring naturally acidic deep ocean waters to the surface.
“We went beyond the traditional approach of looking at dollars lost or species impacted; we know these fisheries are lifelines for native communities and what we’ve learned will help them adapt to a changing ocean environment,” said Jeremy Mathis, Ph.D., co-lead author of the study, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle, and the director of the University of Alaska Fairbanks School of Fisheries and Ocean Sciences Ocean Acidification Research Center.
As for Dungeness crab, Sarah Cooley, a co-author of the Alaska study, who was with the Woods Hole Oceanographic Institution at the time, told Northwest Coast Energy News, “The studies have not been done for Dungeness crab that have been done for king and tanner crab, that’s something we’re keenly aware of. There’s a big knowledge gap at this point.” She says NOAA may soon be looking at pilot study on Dungeness crab.

Risk to Salmon, Mackerel and Herring
In a 2011-2013 survey, a NOAA-led research team found the first evidence: “that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring.”
The survey estimated that the percentage of pteropods along the west coast with dissolving shells due to ocean acidification had “doubled in the near shore habitat since the pre-industrial era and is on track to triple by 2050 when coastal waters become 70 percent more corrosive than in the pre-industrial era due to human-caused ocean acidification.”
That study documented the movement of corrosive waters onto the continental shelf from April to September during the upwelling season, when winds bring water rich in carbon dioxide up from depths of about 120 to 180 metres to the surface and onto the continental shelf.
“We haven’t done the extensive amount of studies yet on the young salmon fry,” Cooley said. “I would love to see those studies done. I think there is a real need for that information. Salmon are just so so important for the entire Pacific Northwest and up to Alaska.”
In Prince Rupert, Barb Faggetter, an independent oceanographer whose company Ocean Ecology has consulted for the fisherman’s union and NGOs, who was not part of the study, spoke generally about the threat of acidification to the region.
She is currently studying the impact of the proposed Liquified Natural Gas terminals that could be built at Prince Rupert near the Skeena River estuary. Faggetter said that acidification could affect the species eaten by juvenile salmon. “As young juveniles they eat a lot of zooplankton including crustaceans and shell fish larvae.”
She added, “Any of the shell fish in the fishery, including probably things like sea urchins are all organisms that are susceptible to ocean acidification because of the loss of their capacity to actually incorporate calcium carbonate into their shells.”
Faggetter said her studies have concentrated on potential habitat loss near Prince Rupert as a result of dredging and other activities for liquified natural gas development, She adds that ocean acidification “has been a consideration that climate change will further worsen any potential damage that we’re currently looking at.”
Her studies of the Skeena estuary are concentrating on “rating” areas based on the food supply available to juvenile salmon, as well as predation and what habitat is available and the quality of that habitat to identify areas that “are most important for the juvenile salmon coming out of the Skeena River estuary and which are less important.”
She said that climate change and ocean acidification could impact the Skeena estuary and “probably reduce some of the environments that are currently good because they have a good food supply. If ocean acidification reduces that food supply that will no longer be good habitat for them” [juvenile salmon].
Bongo nets are deployed up to 200 meters deep to catch marine snails (pteropods), which are indicators of the progress of ocean acidification. The pteropod samples were collected during the U.S. West Coast survey cruises in 2011 and 2013. Unlike the US, Canada’s DFO is using models to track what’s happening to pteropods. (NOAA)
The August 2011 NOAA survey of the pteropods was done at sea using “bongo nets” to retrieve the small snails at depths up to 200 metres. The research drew upon a West Coast survey by the NOAA Ocean Acidification Program in that was conducted on board the R/V Wecoma, owned by the National Science Foundation and operated by Oregon State University.
Nina Bednarsek, Ph.D., of NOAA’s Pacific Marine Environmental Laboratory in Seattle, the lead author of the April pteropod paper said, “Our findings are the first evidence that a large fraction of the West Coast pteropod population is being affected by ocean acidification.
“Dissolving coastal pteropod shells point to the need to study how acidification may be affecting the larger marine ecosystem. These near shore waters provide essential habitat to a great diversity of marine species, including many economically important fish that support coastal economies and provide us with food.”
Ecology and economy
Today’s study on the effects of acidification on the Alaska fishery study examined the potential effects on a state where the fishing industry supports over 100,000 jobs and generates more than $5 billion in annual revenue. Fishery-related tourism also brings in $300 million annually to the state.

The study also shows that approximately 120,000 people or roughly 17 percent of Alaskans rely on subsistence fisheries for most, if not all of their dietary protein. The Alaska subsistence fishery is open to all residents of the state who need it, although a majority of those who participate in the subsistence fishery are Alaska’s First Nations. In that way it is somewhat parallel to Canada’s Food, Ceremonial and Social program for First Nations.
“Ocean acidification is not just an ecological problem—it’s an economic problem,” said Steve Colt, Ph.D., co-author of the study and an economist at the University of Alaska Anchorage. “The people of coastal Alaska, who have always looked to the sea for sustenance and prosperity, will be most affected. But all Alaskans need to understand how and where ocean acidification threatens our marine resources so that we can work together to address the challenges and maintain healthy and productive coastal communities.”
The Alaska study recommends that residents and stakeholders in vulnerable regions prepare for environmental challenge and develop response strategies that incorporate community values and needs.
“This research allows planners to think creatively about ways to help coastal communities withstand environmental change,” said Cooley, who is now science outreach manager at Ocean Conservancy, in Washington, D.C. “Adaptations can be tailored to address specific social and environmental weak points that exist in a community.
“This is really the first time that we’ve been able to go under the hood and really look at the factors that make a particular community in a borough or census are less or more vulnerable from changing conditions resulting from acidification. It gives us a lot of power so that we don’t just look at environmental issues but also look at the social story behind that risk.”
As for the southern part of the Alaska panhandle nearest British Columbia, Cooley said, “What we found is that there is a high relative risk compared to some of the other areas of Alaska and that is because the communities there undertake a lot of subsistence fishing, There tend not be a whole lot of commercial harvests in the fisheries there but they are very very important from a subsistence stand point… And they’re tied to species that we expect to be on the front line of acidification, many of the clam species that are harvested in that area and some of the crab species.”
Long term effects
Libby Jewett, Director of the NOAA Ocean Acidification Program and author of the pteropod study said, “Acidification of our oceans may impact marine ecosystems in a way that threatens the sustainability of the marine resources we depend on.
“Research on the progression and impacts of ocean acidification is vital to understanding the consequences of our burning of fossil fuels.”
“Acidification is happening now,” Cooley said. “We have not yet observed major declines in Alaskan harvested species. In Washington and Oregon they have seen widespread oyster mortality from acidification.
“We don’t have the documentation for what’s happening in Alaska right now but there are a lot of studies staring up right now that will just keep an eye out for that sort of thing, Acidification is going to be continuing progressively over the next decades into the future indefinitely until we really curb carbon dioxide emissions. There’s enough momentum in the system that is going to keep acidification advancing for quite some time.
“What we need to be doing as we cut the carbon dioxide, we need to find ways to strength communities that depend on resources and this study allows us to think differently about that and too really look at how we can strengthen those communities.
Faggetter said. “It’s one more blow to an already complex situation here, My study has been working particularly on eel grass on Flora Bank (pdf) which is a very critical habitat, which is going to be impacted by these potential industrial developments and that impact will affect our juvenile salmon and our salmon fishery very dramatically, that could be further worsened by ocean acidification.”
She said that acidification could also be a long term threat to plans in Prince Rupert to establish a geoduck fishery (pronounced gooey-duck).
The popular large 15 to 20 centimetre clam is harvested in Washington State and southern BC, but so far hasn’t been subject to commercial fishing in the north.
NOAA said today’s study shows that by examining all the factors that contribute to risk, more opportunities can be found to prevent harm to human communities at a local level. Decision-makers can address socioeconomic factors that lower the ability of people and communities to adapt to environmental change, such as low incomes, poor nutrition, lack of educational attainment and lack of diverse employment opportunities.
NOAA’s Ocean Acidification Program and the state of Alaska are also developing tools to help industry adapt to increasing acidity.
The new NOAA study is the first published research by the Synthesis of Arctic Research (SOAR) program. which is supported by an inter-agency agreement between NOAA’s Office of Oceanic and Atmospheric Research and the Bureau of Ocean Energy Management (BOEM) Alaska Region.
Tropical fish are migrating into what were once temperate water as a result of ocean warming and that poses a serious threat to the areas they invade, because they overgraze on kelp forests and seagrass meadows, according to a new study from the University of New South Wales in Australia
The study says the harmful impact of tropical fish is most evident in southern Japanese waters and the eastern Mediterranean, where there have been dramatic declines in kelps.

There is also emerging evidence in Australia and the US that the spread of tropical fish towards the poles is causing damage in the areas they enter.
“The tropicalisation of temperate marine areas is a new phenomenon of global significance that has arisen because of climate change,” according to the study lead author, Dr. Adriana Verges, of the University of New South Wales.
“Increases in the number of plant-eating tropical fish can profoundly alter ecosystems and lead to barren reefs, affecting the biodiversity of these regions, with significant economic and management impacts.”
The study is published in the journal Proceedings of the Royal Society B.
As the oceans have warmed and the climate has changed, hotspots are developing in regions where the currents that transport warm tropical waters towards the poles are strengthening.
Increased flow of the East Australian Current, for example, has meant waters south-east of the continent are warming at two to three times the global average.
Tropical fish are now common in Sydney Harbour during the summer months.
Japan, the east coast of the US, northern Brazil and south eastern Africa are also strongly influenced by coastal currents that transport warm tropical waters.
“In tropical regions, a wide diversity of plant-eating fish perform the vital role of keeping reefs free of large seaweeds, allowing corals to flourish. But when they intrude into temperate waters they pose a significant threat to these habitats. They can directly overgraze algal forests as well as prevent the recovery of algae that have been damaged for other reasons,” Dr Verges said.
Tropical fish expanding their ranges into temperate areas include unicornfish, parrotfish, and rabbitfish.
The study authors include researchers from Australia, the US, Spain, Singapore, the UK and Japan.
Kelp disappears in southern Japan
The study reports that more than 40 per cent of the kelp and algal beds have disappeared since the 1990s, a phenomenon known in Japan as isoyake.
Tropical species including rabbitfish and parrotfish appear to be mainly responsible.
Although these fish have been present for a long time, their annual grazing rates have increased dramatically as ocean temperatures in winter have risen. Corals now dominate the ecosystem in many locations. The changes have led to the collapse of the abalone fishery.
Rabbit fish expand in eastern Mediterranean
Tropical fish moved into the eastern Mediterranean from the Red Sea after the opening of the Suez Canal. In recent decades, rabbitfish numbers have increased, resulting in hundreds of kilometres of deforested areas and a 40 per cent decrease in the variety of marine species.
As the Mediterranean warms the rabbitfish are expanding their range westward, putting other shallow ecosystems at risk.
Gulf of Mexico
There has been a more than 20-fold increase in the number of parrotfish in the Gulf of Mexico – a species which consumes seagrass at five times the rate of native grazers. The number of plant-eating green turtles and manatees has also increased.
Australia
In Western Australia, emerging evidence suggests that increases in the number of tropical fish are preventing the recovery of kelp forest damaged by a heat wave in 2011.
In eastern Australia, kelp has disappeared from numerous reefs in the past five years and Dr Verges’ research suggests intense grazing by tropical fish on the kelp preceded this.
Zone maps for the North Coast marine draft plan. (MAPP)
District of Kitimat Council has urged residents to turn out in large numbers for consideration of the North Coast Draft Marine Plan at the Kitimat Valley Institute Tuesday, May 13, from 5:30 to 8:30.
In introducing the motion, Mayor Joanne Monaghan said she was worried that not enough Kitimatians, especially charter operators, boaters and fishers were aware of the meeting.
Another council member privately said he was worried that the Open House and Forum weren’t publicized enough so that the town could be checked off as having “been consulted.”
MAPP stands for Marine Planning Partnership for the North Pacific Ocean.
According to the documents the purpose of the North Coast Marine Plan “is to provide recommendations for achieving a sustainable balance between ecosystem health, social and cultural well-‐being and economic development through an ecosystem-‐based approach to planning and management.”
The plan is all about managing “common First Nation and provincial interests related to marine areas.”
The parners include the province and the Skeena First Nations Stewardship Society (NCSFNSS), representing the Metlakatla, Kitsumkalum, Kitselas, Haisla, Gitga’at, and Gitxaala Nations.
According to the doucments the North Coast plan area covers 27,000 kilometres of coastline;
that is indented with deep fjords and dotted with thousands of islands. It is a region of profound beauty, significant ecological diversity and remarkable cultural richness. Prince Rupert, Terrace and Kitimat are the largest communities in the North Coast plan area, which supports an overall population of approximately 42,000.
According to the summary of the plan:
The physical complexity of the North Coast includes a range of ecosystem types, including important estuaries that support distinct marine ecosystems and species. A diverse range of economic and community activities occur within the North Coast plan area. Commercial fisheries and associated processing facilities and logging have supported communities along the coast since the early 1900s. These activities continue to be important to the well-‐being of coastal communities. Port activities centered around the communities of Prince Rupert, Kitimat and Stewart, and active recreational fishing and tourism sectors, continue to be strong economic drivers in the area. North Coast First Nations living in the region have distinct cultural and spiritual heritages that are intricately linked to the marine environment and the long-‐standing sustainable use and management of marine resources.
The plan appears to overlap some areas where there have been environmental assessments of the Northern Gateway and the numerous liquified natural gas proposals.
The plan summary goes on to say:
The draft plan brings together science and Aboriginal knowledge, input from the technical staff of NCSFNSS (representing the Gitga’at, Gitxaała, Metlakatla, Kitsumkalum, Kitselas and Haisla Nations) and the Province. Key information and direction was provided by First Nations strategic marine use plans and existing provincial planning and policy documents.
Ecological, cultural and social and economic data sources were compiled and analysed by the joint technical team and contract support. Relevant background scientific reports and technical documents from the Pacific North Coast Integrated Management Area (PNCIMA) process were also used, along with the BC Marine Conservation Analysis. Additional information was drawn from government reports and publications, academic literature, industry or sector publications, discussions with experts and local knowledge. Advice was also incorporated from the North Coast Marine Plan Advisory Committee and public and stakeholder engagement.
The Pacific North Coast Integrated Management Area process was killed by the Harper government in the fall of 2011 . The decision to kill the PNCIMA was officially for budget reasons, but general speculation at the time was that Harper and then Natural Resources Minister Joe Oliver wanted to kill PNCIMA as one way of ensuring the government could push through the Northern Gateway project. The MAPP program was set up by the province and First Nations as a reaction to Harper’s decision.
