Capitalism and an Impending Wild Salmon Apocalypse
|(by Kim Petersen) - That sea lice from salmon farming pens imperil wild salmon populations is known.1 A recent article in the respected academic journal Science has confirmed these earlier reports. 2 But more ominously, the article authors warn that the sea lice threaten a 99% collapse in pink salmon population
expected in four salmon generations.
The culprit is corporate salmon farming whose pens provide a platform where the sea lice can proliferate. The wild juvenile pink salmon that venture to the sea past these salmon farms are at risk of picking up sea lice.
"If nothing changes, we are going to lose these fish."
Martin Krkoek, lead author on Science
paper warning of impending collapse
of wild pink salmon population
Lead author Martin Krkoek and his colleagues concluded:
To isolate sea lice from other factors affecting pink salmon populations, the researchers used data from the Canadas Department of Fisheries and Oceans that enumerate adult salmon returning to BC rivers each year since 1970. The data allowed researchers to compare populations of pink salmon exposed and unexposed to salmon farms.
In a press release, Krkoek and his co-authors calculated that sea lice have killed more than 80 percent of the annual pink salmon (Onchorhynchus gorbuscha) returns to British Columbias Broughton Archipelago. 4
The authors results indicate wild salmon populations are endangered and suggest that large-scale aquaculture should be carefully considered for its effect on wild species.
The Broughton Archipelago has an 80-kilometer gauntlet of fish farms that juvenile salmon must negotiate on the way to the open ocean. Study co-author Alexandra Morton, director of the Salmon Coast Field Station, located in the Broughton said, Salmon farming breaks a natural law. In the natural system, the youngest salmon are not exposed to sea lice because the adult salmon that carry the parasite are offshore. But fish farms cause a deadly collision between the vulnerable young salmon and sea lice. They are not equipped to survive this, and they dont.
The cause, according to Krkoek is simple: In the Broughton there are just too many farmed fish in the water. If there were only one salmon farm this problem probably wouldnt exist.
What to do? Mark Lewis, a mathematical ecologist at the University of Alberta, identified two possible solutions: closed containment and moving farms away from rivers.
Daniel Pauly, Director of the University of British Columbias Fisheries Centre, put it in perspective: If industry says its too expensive to move the fish farms or contain them, they are actually saying the natural system must continue to pay the price. They are, as economists would say, externalizing the costs of fish farming on the wild salmon and the public.
Corporate-Government Collusion in Collapse of Pink Salmon
The BC Liberal [sic] Party has been supporting an increase in the number of salmon farm operations. 5 The salmon farming industry has reaped a whirlwind of criticism. Corporate salmon farming in BC is Norwegian dominated, and a section of the Norwegian media jumped to a nationalistic defense of the Norwegian concerns.
Overall, the Norwegian media reaction was mixed. Norways largest media house, NRK, headlined with Norwegian company wipes out wild salmon.6 Industry media portrayed the matter differently. Næringslivsavisen ran: Attack on Norwegian salmon giants. 7 Dagens Næringslivs headline was: Frontal attack against Norwegian salmon giants. 8 They attacked the prestigious Science journal and denounced the scientists as activists. Morton was labeled an environmentalist, as was Krkoek. One wonders about what is so objectionable about being an environmentalist. Nonetheless, one would hardly hurl the environmentalist label at the corporatists.
Marine Harvest Canada CEO Vincent Erenst complained the Science article authors are not independent researchers. 9 Erenst charged that the scientists are engaged in agenda research, which is not research. He further asserted, These researchers have made up their minds they would arrive at a predetermined result, then have ruled out everything that conflicts with their hypothesis. Nowhere in the interview is evidence provided to back up his allegations.
Ian Roberts, Marine Harvest Canadas communications director, chimed in, I believe people are starting to get a little weary of this type of Doomsday prophecy.9 These are sly digs bordering on ad hominem that do not address the scientists research results and conclusions.
The Pacific Salmon Forum responded, The extent of the impact of salmon farming on wild salmon is still not fully understood, nor is there a consensus of scientists on the best ways to minimize that impact.
This is an unsurprisingly wishy-washy statement coming from a panel of seven individuals appointed by the BC government, whose ruling Liberal Party is a major recipient of political contributions from the salmon-farming industry. 10 Presumably, the Pacific Salmon Forum holds that a looming 99 percent eradication of existing wild salmon stocks is worth the risk?
Mary Ellen Walling, executive director of the British Columbia Salmon Farmers Association (BCSFA) stated that Krkoek and Morton are well known for their hard line views about salmon farming. 10 One wonders if this is similar to the hard-line rejection of environmental concerns by the salmon-farming industry lobby.
The BCSFA once claimed it would like to work in partnership to ensure wild salmon are protected.11
Krkoek criticizes the salmon farming industry for lacking the competence to realize the problem. We have tried to co-operate for years, but it has been difficult. The salmon farming industry does not want to talk with environmentalists at all, and they are skeptical of the science around this, he said.12
Nevertheless, when criticisms were directed to the study, Krkosek compellingly refuted the criticisms.13
Given what is at stake, Morton called for public input: Wild salmon are enormously important to the ecosystem, economies, and culture. Now it is clear they are disappearing in place of an industry. People need to know this and make a decision what they want: industry-produced salmon or wild salmon.
