Interesting report on the effects of ISA on the Chilean Salmon farming industry.....  http://www.gaalliance.org/update/GOAL11/AdolfoAlvial.pdf

The last page contains a significant credit to Dr Kibenge. This is the same Dr. Kibenge that the DFO and CFIA suggested was doing bad science and that his diagnosis of ISA in wild BC salmon was a mistake.....  ???

Two of the fisheries that have been rated as sustainable might cause a little consternation among those who look a little closer. One is the Alaska ranched salmon program where hatchery reared fish are released to "pasture" on a free range basis. That fishery is considered by many to be upsetting the food web in the North Pacific and cause declines in many stocks among which are the wild salmon stocks. The other declared "sustainable" fishery is the BC sockeye fishery in it's entirety. Never mind that we are in a middle of a judicial inquiry investigating the precipitous decline of the largest of the stocks, the fishery proudly bears the label "sustainable" and can be sold to consumers by organizations like the one posted as an ecologically friendly choice.

Here is an interesting correlation between the Alaskan hatchery produced ranched salmon and Fraser River Sockeye returns. Interesting to note that the Alaskan hatcheries are now releasing more than 1.5 billion juveniles every year, mostly pink and chum.

Also interesting to note that the counting fences on the Columbia reported more than 1000 pinks returning this year. What makes that bit of data interesting is that there are no pink runs on the Columbia.

Also, for those interested in what was really said at the hearings, the last day's transcript was posted this morning so all the laundry is now hung out on the clothesline.

I'm not sure how to take your post....   The way that you either include or exclude information in order to make a point is hilarious!  ;D  ;D  On the other hand maybe you are just naive and really believe there is a correlation.... 

How do you explain the sockeye returns for 2010 ($35 million) and 2011 ($5 million)?  I also can't believe that you of all people are posting a chart containing data compiled by Alex Morton....  :o

If the fish farms were forthcoming with their sea lice and disease data then we could draw up a chart showing the correlation between sockeye returns and fish farms killing the fry off with their diseases and sea lice..   Unfortunately as long as the farms are keeping this data secret that won't be possible!

I'm beginning to think you intentionally miss the point just for the sake of having an argument and venting a bit of your seemingly limitless bile.

It's interesting how you change the subject and attack when you; 1) don't have the answer for a question you have been asked or 2) you realize that a point you were trying to make just doesn't stand up.

You suggest that there is an "interesting correlation" between Alaskan hatchery produced ranched salmon and Fraser River Sockeye returns as if that is the reason the Fraser sockeye have declined. Yet if you had of included current data it is obvious that there is no correlation whatsoever. In a previous post you seem to suggest that positive correlation is not science. "While attempting to find gross correlations is hardly "science" since a positive correlation doesn't establish causation, finding a lack of correlation is a more significant and meaningful result."

So what is the story.... from your "scientific" perspective?

A correlation is an observation of how two variables change relative to each other over time. It does not indicate a causative relationship. That chart compares the variance of Alaskan hatchery releases relative to variance in the returns of Fraser sockeye over a specified period. Whether you can understand the concept or not, it is an interesting correlation that is illustrated by that data set. Only a fool would attempt to argue the meaning of the correlation without extensive further understanding of the situation and only a fool would attempt to suggest that the illustrated correlation between those two variables doesn't exist. Is that what you are doing?

including from Stacey Gaiga writing in the Comox Valley Echo:

 

"As a salmon farming biologist, it's obvious Terry Neilsen couldn't care less what implications any job that sacrifices innocent lives has on the human condition, for a paycheque..... With his head in the sand, just as he is a salmon farming biologist, I imagine it took great courage to explain how short term monetary gain and subsequent pain and suffering is worth the sacrifice, for his lifestyle while he lives on this earth. He and the other ignoramus idiots that refuse to acknowledge, or care, that we need healthy land, air and water to survive as a species, like all the other species we share this life with."

 

From The Seattle Post-Intelligencer:

 

"Suspicious science award: When scientists detected the Infectious Salmon Anemia Virus in West Coast salmon, the Canadian Food Inspection Agency claimed they could find no evidence of same. E-mails revealed the CFIA treating a possible epidemic as a public relations problem. "It is clear we are turning the PR tide in our favor," said one leaked e-mail, which added a few lines later: "One battle is won, now we have to nail the surveillance piece, and we will also win the war."

 

And from the Burnaby News Leader interviewing Alan James of the Stoney Creek Environment Committee.

 

"Q:What do you think is the most pressing issue for the environment/streamkeeping right now and why?

In B.C., there is an outbreak of infectious salmon anemia (ISA) virus in B.C.’s wild salmon. The probable cause is that Department of Fisheries and Oceans allowed B.C. fish farms to import infected Atlantic salmon eggs from Europe, where the outbreak began and decimated Norwegian fish farms. The virus spread to Chile with similar consequences. Now it is here.

Q:What would be the best thing that could happen for the environment in 2012?

That DFO would take responsibility for the outbreak of ISA virus in B.C.’s wild salmon and require salmon farms to use closed ponds, not the open ocean."

Salmon cages drift away in Ireland

 

Officials attempt to reel in 30 meter-wide cages, which pose danger to boats.

 

Loose salmon cages in Ireland’s Shetland islands have sparked concern with

officials.

 

The Shetland Coastguard has appealed for help to reel in a dozen large salmon

cages which have broken free of their moorings in the North Sea, reports the BBC

News.

 

The 30 meter-wide cages could be dangerous to navigation around the south coast

of Unst.

 

It is unclear how many fish were in each cage, or how much the incident will

cost their owners, reports The Press Association. The cages are operated by

Lakeland Unst Ltd, which operates between the islands of Yell, Fetlar and Unst

in an area known as Bluemull Sound, which covers approximately 13 square miles.

 

"They are big cages and they are all attached to one another in one big lump,

although they are starting to break up now," a coastguard spokesperson told the

The Press Association.

 

"There was a boat out there that got a hold of it but he didn't have the power

to tow it. In fact, it was towing him. It is drifting around there so it is a

threat to navigation...I doubt very much that there's any fish left in them. It

will be a fair expense."

 

It is thought the cages, which should be filled with salmon ready for harvest

and sale, were cast adrift on Christmas Eve during high winds.

Columns: Alexandra Morton On Atlantic Salmon – How Did This Happen?
Posted on 26 December 2011
Tags: Alexandra Morton, Atlantic Salmon, DFO, Dr.Sally Goldes, Environment, environmentalist, fish, Pacific Salmon
By Alexandra Morton. There were large Atlantic salmon imports to BC from eastern Canada decades ago in a deeply misguided venture to establish Atlantic salmon among healthy Pacific salmon stocks. They did not survive for long, but could have left a legacy of pathogens.
This blog reports on a series of excerpts from provincial and federal documents chronicling the conversations around the more recent Atlantic salmon egg imports into BC waters for the purpose of salmon farming. Since the 1980s, people in government have voiced serious biological concerns, trying to defend BC. Most recently today Dr. Sally Goldes who worked for the Province of BC in fish health came forward, Times Colonist article. Despite their efforts the threat of trade sanctions appears to have dominated decision making. The source of eggs changes, suggesting problems, and each time it is preceded by industry pressure. The biology caved to the demands of commerce. But the irony is that the pristine, oxygenated, nutrient-rich waters of British Columbia – that the industry so desperately craves – has become the casualty. All our lines of defence against viral activity in salmon farms were removed one-by-one. There are some heroes in government who really tried and are still trying to protect BC wild salmon.

1982 – Canadian government and Norwegian and Canadian business interests meet:

• “have requested consideration of alternative approaches to inspection and certification of salmon culture facilities” (Tim Carey, DFO, Senior Program Advisor, Aquaculture and Fish Health, letter to Pritchard, DFO* Aquaculture & Resource Development re: importation of Atlantic salmon from Norway)

1984 – Fisheries and Oceans Canada (DFO) approves limited importation of Atlantic salmon, although this is not made public.

1985 – Draft Importation of Salmonids Policy states:
• Imports will cease March 1989
• Source hatcheries must meet Canadian Fish Health Protection Regulations
• 12 month quarantine
• 300,000 eggs per hatchery to maintain reasonable security

• “I am getting increasingly anxious about our importing of Atlantic eggs. My concern is shared by many of my colleagues in both provincial and federal agencies…The fish health measures agree-to jointly by DFO and ourselves in the fall of 1984 are not foolproof. They are based on statistical sampling, so we are taking a risk when it comes to the introductions of virus. That means a risk to the nearly one-billion-dollar wild salmonid fisheries of British Columbia” (Dave Narver, MOE* to Anthony ADM, MOE, Feb 26)

130,000 Atlantic salmon eggs imported from Scotland

1986 – Import policy remains unsigned and is not public

• “…We are deeply concerned with the fact that the risk of exotic diseases is dependent on both the number of imports and their size… Government has made a commitment to support aquaculture, but surely not at the risk of a nearly $1 billion resource in the wild salmon fisheries of British Columbia. The direction the aquaculture industry wants us to go will insure that we import unwanted diseases that can impact on government hatcheries and wild stocks” (Narver, MOE to Gunn, Pacific Aqua Foods, Nov 6).

• “…Imported fish could be more susceptible to local pathogens than native stocks. An outbreak of disease in an imported stock due to a local pathogen, as well as causing losses to that stock could result in a dramatic increase in the pathogen loads in the system to a level which otherwise refractory native fish may not be able to withstand.” (CFSAC Advisory Document 1986) This is an extremely important observation, the unnatural salmon farm environment can cause local pathogens to become dangerous to local stocks.

• “To start with a general comment, I am disappointed with what appears to be the prevailing attitude of a number for companies, that fish health regulations to protect wild stocks are great, but … If we continue the way the aquaculture industry seems to dictate, we can expect to introduce new diseases.” (Dave Narver, MOE to Dale Blackburn, Stolt Sea Farm Canada Inc.)

1,144,000 eggs imported from Scotland

1987 – Federal-Provincial Policy for the Importation of Live Salmonids was signed, but restrictions were lowered.

• quarantine reduced to 120 days to reduce industry cost of dealing with waste water
• suggestion egg imports continue until 1990 ( Davis, DFO to Chamut, DFO, Jul 23)
• “If challenged in court over denial of any imports, what is the legal likelihood we would be successful in denying imports?” (Chamut, DFO to Davis, DFO, June 27)

1,281,000 eggs imported from Scotland / Washington State

1988 – Davis, DFO’s Regional Director of Science for the Pacific Region suggests extension of egg import to 1991

2,700,000 eggs from Scotland / Washington State

Conti
1990 - U.S. salmon farmers claim Canada import restrictions are a trade barrier.

• “Continued large-scale introductions from areas of the world including Washington State, Scotland, Norway and even eastern Canada would eventually result in the introduction of exotic disease agents of which the potential impact on both cultured and wild salmonids in BC could be both biologically damaging to the resource and economically devastating to its user groups” (Chamut former ADM, DFO, to Sarna, Director of Pacific Rim & Trade, Policy Division, International Directories, DFO, 1990)

1991 – The threat of a “Free Trade Ruling” remains, fish farm industry pushes for use of known diseased stocks.

• “I am very concerned about the discussion which took place about the egg import policy and proposed changes… I think [they] have gone too far… The proposed revisions not only open the window indefinitely but essentially allow for unlimited numbers of eggs. I know your Department argues that this has to done to avoid a Free Trade ruling…” (Narver, MOE to Chamut, DFO, Sept 30)

• “As we have no other disease-free source available [other than Iceland] anywhere in the world, I am requesting that you reconsider your position, particularly in the light of the expected change in the DFO regulations” (Needham, Director Aquaculture, BC Packers, to Hoskins, DFO, Dec 3 )

• “DFO and MOE are responsible for the protection of wild and cultured salmonid stocks in British Columbia. Both…agencies firmly believe that repeated large scale shipments of salmonid eggs…expose BC’s wild and farm salmonid stocks to unnecessary disease risk.” (Ginetz, DFO to BC Trout & Char Producers, Jan 16)

• Document titled, The Need for Restrictions on the Importation of Atlantic Salmon into B.C. Atlantic salmon eggs “clearly carry the risk of the inadvertent introduction of exotic disease, or exotic strains of indigenous agents.” (Gary Hoskins, Scientist, DFO memo, Jul 13)

• “Perhaps most important is the fact that new diseases are continually surfacing – their dynamics…are totally unknown. To suggest therefore that vertical transmission should not be a concern would be irresponsible” (Chamut, DFO to Emberley, Director General, Inspection Services Directorate, Jun 11)

• “The proposed revisions not only open the window indefinitely but essentially allow for unlimited numbers of eggs. I know your Department argues that this has to done to avoid a Free Trade ruling.” (Narver, MOE to Chamut, DFO Sep 30)

• “I have the distinct feeling that the seriousness of the interaction between wild/farmed fish has been downplayed by some of your staff” (Narver, MOE to Chamut, DFO Sep 30)

• “I want to therefore emphasize that despite allegations that restrictions were introduced to limit trade for the benefit of BC producers, our foremost and only concern was to protect our wild and cultured stocks from exotic disease… There are a host of examples including cases in the US… where new diseases were accidentally introduced due to inadequate regard for fish health, resulting in significant economic losses to commercial and sport fisheries and more recently the salmon farming community.” (Chamut, DFO to Barrows, Free Trade Coordination Divisions, External Affairs & International Trade, Jan 23)

• “strongly urg[ing] DFO and BCMOE to modify existing policies to provide greater access to larger commercial quantities of Atlantic salmon eggs.” (BC Salmon Farmers Association to Chamut, DFO Jul 15).

735,000 eggs imported from New Brunswick / Ireland / Washington State

1992 – Importation Policy redrafted – signed by Pat Chamut

• No limit on number of eggs per license,
• quarantine reduced from 12 mos., to 120 days or body weight of 3g.

• BC Salmon Farmers Association: “imported fertilized eggs would be more competitive with domestically produced eggs if hatchlings did not have to be raised under quarantine conditions.”

640,000 eggs New Brunswick / Washington State

1993 – The Provincial and Federal government agencies (DFO, MAL*, MOE) Wild/Farmed Salmonid Interactions. Despite all the discusion above and no literature cited it reads:

• “There is also no evidence that wild fish in BC are placed at serious risk from disease occurrence in farmed fish.” (Apr 6).

• Washington State exports 47 million salmon eggs worldwide (10% to BC)

1,447,000 eggs from New Brunswick / Ireland / Washington State

1995 – Pressure from US for BC to relax egg/smolt import regulations

• “Major salmon egg exporters from Washington State agreed that there would be great market potential for their Atlantic salmon eggs in British Columbia if existing import restrictions were removed.” (International Trade – Canada’s Restriction on Certain Salmon Imports, Report to U.S. Senate Slade Gordon, April 1995, GAO/GGD-95-117)

• “Two BC salmon farming companies wish to import Atlantic salmon eggs from…Icelandic company which is not certified under the Canadian Fish Health Protection regulations (FHPR)
• Failure to provide permission for egg importation may trigger a trade challenge under the World Trade Organization…
• Additionally, DFO could also be viewed as causing a competitive disadvantage of the aquaculture industry by denying them access to alternate strains.”
