With thanks to Ironnoggin who posted this elsewhere............

Here are some further responses from Dr. Gary Marty with respect to that email conversation that AF posted but a small piece of.


Absolon, I hope you aren't implying that I posted only part of an email conversation, purposely leaving out the emails you posted..... because you know that the one I posted was the only one available when I posted it.

In Gary Marty's subsequent e-mails he appears to have backed down from his arrogant attitude, probably because he was made aware that his initial email was being circulated on a number of fishing forums. It's obvious that at that point he put on his salmon farming PR hat and lost the attitude...... I'm sure there is some truth in what he wrote, it's just that it's difficult sorting out the fish farm rhetoric from the facts....

The following article seems to refute your's, Gary Marty's, CFIA's and DFO's (the fish farm industry in general) stance that ISAV is only detrimental to Atlantic salmon and doesn't affect wild salmon. Of course the fish farm industry would be well aware of this publication. But then I guess the denial is just part of the PR campaign to "win the war". Science seems to be pretty irrelevant when it doesn't fit the industries agenda.

BC Fish feedlots are saying that ISAv does not affect Coho. Perhaps they should read this paper.

ABSTRACT: The isolation of infectious salmon anaemia virus (ISAV) from asymptomatic wild fish species including wild salmon, sea trout and eel established that wild fish can be a reservoir of ISAV for farmed Atlantic salmon. This report characterizes the biological properties of ISAV isolated from a disease outbreak in farmed Coho salmon in Chile and compares it with ISAV isolated from farmed Atlantic salmon in Canada and Europe. The virus that was isolated from Coho salmon tissues was initially detected with ISAV-specific RT-PCR (reverse transcription-polymerase chain reaction). The ability of the virus to grow in cell culture was poor, as cytopathology was not always conspicuous and isolation required passage in the presence of trypsin. Virus replication in cell culture was detected by RT-PCR and IFAT (indirect fluorescent antibody test), and the virus morphology was confirmed by positive staining electron microscopy. Further analysis of the Chilean virus revealed similarities to Canadian ISAV isolates in their ability to grow in the CHSE-214 cell line and in viral protein profile. Sequence analysis of genome segment 2, which encodes the viral RNA polymerase PB1, and segment 8, which encodes the nonstructural proteins NS1 and NS2, showed the Chilean virus to be very similar to Canadian strains of ISAV. This high sequence similarity of ISAV strains of geographically distinct origins illustrates the highly conserved nature of ISAV proteins PB1, NS1 and NS2 of ISAV. It is noteworthy that ISAV was associated with disease outbreaks in farmed Coho salmon in Chile without corresponding clinical disease in farmed Atlantic salmon. This outbreak, which produced high mortality in Coho salmon due to ISAV, is unique and may represent the introduction of the virus to a native wild fish population or a new strain of ISAV.

Well done AF! I am clear that you posted all that was available at the time and that you weren't editing. After seeing one of the emails sent to Marty that resulted in his responses, I'm surprised he responded in such a civil manner to some very ignorant attacks on his integrity by someone obviously very ill informed.

The conclusion to the paper you link to bears reading:



......It is not known when and how ISAV was introduced into Coho salmon in Chile. ISAV can infect a wide range of fishes (Nylund et al. 1994, 1995, 1997), but in wild fish species, it usually produces an asymptomatic infection (Nylund et al. 1999). Within Norway, Scotland and the Canadian east coast considered the normal geographic distribution), ISAV has been documented to cause disease outbreaks only in marine farmed Atlantic salmon. Wild fish with virus but no disease are common (Nylund et al. 1999, Devold et al. 2000), suggesting that asymptomatic or mild infection usually occurs among wild fish in those regions. Similarly, substantial virulence in any other farmed fish species has not been reported. Therefore, an outbreak producing high mortality in Coho salmon is unusual for ISAV and may represent introduction from a native wild fish population or a new strain of ISAV. In both of these cases, migratory wild fish and importation of commercial fish eggs may play important roles in the natural transmission cycles.

Also worth noting is that the virus discussed in the paper didn't affect Atlantics and is related to the North American strain. The particular strain hasn't been isolated again in Chile; the 2007 outbreak was associated with the European strain of the ISAV, and while it affected farmed Atlantics, it wasn't reported in the farmed coho.

May interest some, from facebook.

Excellent Environment Minister Erik Solheim – brave man - you're on track!

In a debate in Norway’s parliament January 19th, Mr Solheim compared today’s salmon industry to be in the same situation the heavy industry faced in the 70s. An increasingly strong opinion at that time, forced the heavy industry to take the challenges seriously and to stop finding excuses why not doing something about indu...strial pollution. Instead the industry used their creativity to solve challenges. Industrial pollution is in fact no longer a problem to talk about in the western world

This should be a guideline for today’s aquaculture industry. Instead of using energy to find some professor somewhere in the world who can create doubt that there are genuine environmental problems in the industry, one should rather do something.
Question that the industry must address are lice, escapes, and the immediate emissions from plants. The whole discussion in the parliament is her in norwegian, google translate might work good enough to get a brief picture on this:

From the Globe and Mail.

Free speech
Writers want Ottawa to let scientists ‘speak for themselves’
MARK HUME | Columnist profile | E-mail
VANCOUVER— From Monday's Globe and Mail
Published Sunday, Jan. 22, 2012 8:10PM EST
Last updated Sunday, Jan. 22, 2012 8:49PM EST
 
  Last year, Kathryn O’Hara, then president of the Canadian Science Writers’ Association, wrote an extraordinary letter to Prime Minister Stephen Harper and the leaders of the other national parties.

In that document – remarkable because it was written in a leading democracy not a paranoid dictatorship – she pleaded with government to unshackle its scientists by allowing them to speak freely with the media.

More related to this story
•Researcher suggests ‘salmon leukemia’ is to blame for decline of Fraser sockeye
•Mysterious infection is killing B.C. salmon
•Something fishy about scallop farm?
The CSWA represents more than 500 science journalists, publicists and authors in Canada. Ms. O’Hara recounted a series of incidents that occurred during the year leading up to her letter in which requests for interviews with researchers had been bluntly refused by public affairs handlers, or thwarted by them through endless bureaucratic delays.

Kristina Miller, a Department of Fisheries and Oceans scientist who has done groundbreaking work on emerging salmon diseases on the West Coast, was one of those who was denied permission to talk to the media, even though her research had just been published in the prestigious international journal, Science.

The government’s stifling of Dr. Miller was so extreme that she was even told by DFO officials not to attend workshops at which experts were discussing salmon issues, out of fear media might attend and hear what she had to say.

“We urge you to free the scientists to speak – be it about state of ice in the Arctic, dangers in the food supply, nanotechnology, salmon viruses, radiation monitoring, or how much the climate will change,” Ms. O’Hara wrote. “Take off the muzzles and eliminate the script writers and allow scientists – they do have PhDs after all – to speak for themselves.”

The government did not change its policy. The standard operating procedure still requires that all media requests for interviews be vetted through public affairs officials in Ottawa. Sometimes, scientists are cleared to speak – often they are not.

Contrast that with the “scientific integrity policy” adopted last month by the National Oceanic and Atmospheric Administration in the United States.

NOAA’s new guidelines – which make it clear scientists can speak about their work any time, to anyone – flowed from a memo President Barack Obama sent to the heads of executive departments in 2009. In that missive, he affirmed his support for transparency in government and urged directors to foster a culture of scientific integrity.

“The public must be able to trust the science and scientific process informing public policy decisions,” he wrote.

“Science, and public trust in science, thrives in an environment that shields scientific data and analyses from inappropriate political influence,” John Holdren, assistant to the President for science and technology stated in a later memo. He said the purpose of the initiative was to “strengthen the actual and perceived credibility of government research.”

NOAA’s response is an explicit policy that states “scientists may speak freely with the media and public about scientific and technical matters based on their official work without approval from the public-affairs office or their supervisors.”

Policy guidelines inform staff that if they wish to go beyond talking about their research, and express opinion, they have two choices. They can submit statements of opinion to NOAA’s legal and legislative affairs staff which may, after a lengthy process, issue it as government policy. Or they can simply put on the record that they are speaking as individuals.

“We all have the right to express our opinions publicly on our own time as private citizens. … Thus, your second option is that you will just need to provide a disclaimer indicating you are expressing your opinion and not the opinion of NOAA,” the agency guidelines state.

Talk about being unshackled. All a scientist has to do to express a personal view related to his or her research is to say, “this is my opinion, not government policy.”

The policy is now in force in the U.S.

In Canada, government scientists who want to talk to the media still have to get permission from public-relations officials, who can silence anyone they want.

As Mr. Obama made clear, such an approach calls into question the integrity of science – and the credibility of government

Thanks for posting that Chris!

The aquaculture industry needs to be absolutely transparent if they want to attain any sort of credibility with the public. DFO and CFIA must allow their scientists to speak freely about the science they are doing and the results of the tests without first sending it through their public relations department. The farms need to allow scientists like Miller access, so that they can test the farmed fish. Disease reporting for the farms must be mandatory and made available to the public. The public must be aware of not only what the farms are doing to the environment, but exactly what they are eating when they eat a farmed salmon.

Without transparency you can only assume the worst, because why else would they be hiding the information? Hearing that CFIA is waging a war of PR battles suggests they care about the feedlots a whole lot more than they care about wild salmon. Hearing the pro farmers suggesting we should trust them, because their science says everything is ok....   well how naive do they think we are?

pretty well my thoughts, especially so, the first paragraph. As for CFIA sounds like they have a couple Homeland Security wannabees in the mix instead of scientist/inspectors who are focusing on what is safe and what is not within the food industry.

You only need Spin Doctors if you are up to no good. Transparency is fair to all, it not like this is a national security issue!

They (CFIA) are duty bound to tell the general public what is in our food, all food!
What will happen when folks start buying farmed fish and sending the purchase to a lab for analysis?
Is the lab allowed to actually report back to us?
What if an angler catches a fish and legally keeps said fish, and sends it to a lab for testing of disease and chemicals? is that allowed?
What if analysis of the bought fish has elevated or even unsafe levels of dangerous chemical/s ? what then?

finding your limits is fun, it can also be VERY painful.

If you care about Canada's future, get involved by holding your MLA's & MP's accountable!! don't just be sheep!!

Background info to dangers of Importing Salmon Eggs for Fish Farms

The paper trail is growing that will prove the folly of net pen salmon farms!

Editor's note: In a letter to the editor in Wednesday's Courier-Islander Dr. Ian Alexander, Executive Director, Canadian Food Inspection Agency made the following statement: "I want to be very clear, that to date no trace of ISA has been detected in B.C. salmon."

Also, in another letter to the editor in Wednesday's Courier-Islander, Gary Marty, BC Ministry of Agriculture, made the following statement: "As part of my work as the BC Ministry of Agriculture's fish pathologist, last fall I reviewed... results in our diagnostic laboratory from five farmed chinook salmon re-tested for ISAV.

"Samples from all five fish yielded a band that was very similar to our ISAV-positive control, but when we sequenced the PCR product to determine its identity, it didn't match anything. The closest match was mouse (see Cohen Commission Exhibit #s 2079 and 2080.)
"I view mouse-like results in a test for a salmon virus as evidence of "nonspecific amplification." This means that the test did not work properly and needed to be redone; it is not grounds to report to OIE. The test was repeated several times, and all results were negative - no virus.")

The source of the suspected infectious salmon anemia virus (ISAv) that was reported to be found in BC's wild salmon would have almost certainly from imported Atlantic salmon eggs, the international trade that at one time provided coastal salmon farms with most of their stock. The salmon farming industry, of course, says that ISAv is not here, although evidence given at the Cohen Commission's extraordinary three days of hearings on Dec. 15, 16 and 19 suggests otherwise.

Of four labs testing for ISAv in wild fish samples, the only one seemingly unable to find it is the Canadian Food Inspection Agency's facility in Moncton, New Brunswick, that used degraded tissue samples.

Research tests by a reputable lab in 2004 found 100 per cent infection in Cultus Lake sockeye - inexplicably never pursued by federal agencies responsible for the health of wild salmon. Testimony from Dr. Kristi Miller showing genomic markers in archaic samples of BC wild salmon indicates that ISAv has been here since 1986.

Documents presented at the Cohen Commission suggest that the possible arrival of ISAv coincides with the early importation of Atlantic salmon eggs to West Coast salmon farms. Supporting this connection is a recorded litany of warnings from experts in BC's Ministry of Environment (MOE) and the federal Department of Fisheries and Oceans (DFO), all alarmed about the inherent danger of importing exotic diseases to the West Coast ecology through Atlantic salmon eggs. This evidence is worth noting.

. 1982: representatives of Canada's government meet with Norwegian and Canadian business interests to consider "alternative approaches to inspection and certification of salmon culture facilities" for the importation of Atlantic salmon material from Norway.

. 1984: Canada's DFO approves limited importation of Atlantic salmon material, an event that is not announced publicly.

. 1985: 300,000 eggs are imported, subject to a "Draft Importation of Salmonids Policy" requiring a 12-month quarantine. But Dave Narver of MOE expresses concern to his Assistant Deputy Minister about the policy.

"I am getting increasingly anxious about our importing of Atlantic eggs," he wrote. "My concern is shared by many of my colleagues in both provincial and federal agencies. The fish health measures agreed 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." An additional 130,000 Atlantic salmon eggs are imported from Scotland.

.1986: Narver reiterates his concerns to Pacific Aqua Foods about an unsigned and non-public policy. "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 sends a similar letter of concern to Stolt Sea Farm Canada Inc.

"To start with a general comment, I am disappointed with what appears to be the prevailing attitude of a number of 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." 1,144,000 eggs are imported from Scotland.

. 1987: Federal-Provincial Policy for the Importation of Live Salmonids is signed, but quarantine time is reduced to four months to reduce the industry's cost of dealing with waste water.

Pat Chamut of DFO expresses a trade concern. "If challenged in court over denial of any imports, what is the legal likelihood we would be successful in denying imports?"

1,281,000 eggs are imported from Scotland and Washington State.

. 1990: Salmon farmers in the US claim Canada's import restrictions are a trade barrier. Chamut reiterates his concerns to the Policy Division of Pacific Rim and Trade. "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."

. 1991: Numerous warnings are written by DFO and MOE officials, all concerning the dangers of importing diseases from foreign salmon eggs - a danger compounded by trade agreements allowing the salmon farming industry to import larger numbers of eggs. Narver's letter from MOE to DFO is typical for 1991. "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."

Subsequent to these warnings comes a 1991 letter from BC Packers' Director of Aquaculture to DFO. "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." Regulations are duly relaxed and from 1991 to 2010 at least 23 million eggs are imported into BC waters, mostly from sources other than Iceland.

This evidence from the Cohen Commission indicated that international sources of eggs could be diseased and that the aquaculture industry wanted to import eggs, despite the risks.

Given trade agreements and the political leverage of the salmon farming industry to reduce precautionary regulations - the direction it "seems to dictate," in Dave Narver's damning words - the arrival of ISAv and other exotic diseases in BC's marine ecology is inevitable.

The Cohen Commission: Following traces
By Ray Grigg, Special to Courier-IslanderJanuary 27, 2012

So, why did salmon farmers not find ISAv in their testing of more than 4,700 samples of farmed fish? The sole veterinarian testing their fish was Dr. Gary Marty, who noted more than 1,100 instances of lesions that were commensurate with ISAv, but he always recorded negative results for the viral infection. The industry, therefore, could confidently announce, as it frequently did, "that the ISA virus has never been found in British Columbia" (Times-Colonist, Dec. 16/11).

McDade and Glowaki explain this puzzle. First, not all ISAv strains are lethal so salmon farms might not notice high mortality. Like an influenza, it can exist as a low level infection that only becomes virulent when it mutates - particularly in high population densities at fish farms and hatcheries. But ISAv does impair fish health - especially wild fish in stressful survival conditions - and it leaves identifiable cellular markers. This is what the genomic specialists Drs. Kristi Miller, Fredrick Kibenge and Are Nylund found in their independent sampling of wild salmon tissue.

Was the salmon farming industry concealing evidence of ISAv? Not exactly. The following is the McDade and Glowaki technical explanation:

"The evidence is now clear that Dr. Marty was conducting PCR tests with no confirmed validity. His PCR test was developed in-house, by a master's student. This methodology used a primer that was different from that approved by the OIE or by the Moncton lab. It was a primer that had never been through the validation process, nor even apparently a peer-reviewed publication.
Dr. Kibenge testified that in his opinion this test would not be sensitive to finding ISA." So the "self-invented" test had no validity and "in our respectful submission, this 'non-disclosure' is tantamount to deliberate deception."
DFO had chosen to be "willfully blind" by relying only on the invalid testing of this single lab, and the CFIA was contented to avoid the complexities of discovering ISAv, no such disease was ever found by anyone responsible for detecting it.

Cooke Aquaculture responds quickly to suspicion of virus
February 17, 2012
Cooke Aquaculture has humanely euthanized two cages of fish in Nova Scotia
after routine testing raised suspicion of the Infectious Salmon Anemia (ISA) virus.
This voluntary action is considered as a proactive fish health management
strategy employed by salmon farmers around the world, one that has been taken
by Cooke Aquaculture after thorough risk evaluation.
On Feb 10th, 2012 the suspicion of ISA was raised during routine fish health
surveillance and testing at a salmon farm in Nova Scotia.
Infectious Salmon Anemia (ISA) is a naturally occurring virus that spreads slowly
and is present in wild fish in many parts of the world, including eastern Canada
and the United States. Because ISA is present in the natural environment,
salmon farmers have learned to manage it over many years.
The presence of ISA has NOT been confirmed and the Canadian Food
Inspection Agency is continuing its testing. While ISA is harmful to salmon, it
poses no risks to human health.
While this is only a suspect case of ISA, Cooke has taken the extremely
proactive fish health approach of euthanizing the affected fish immediately rather
than waiting for further testing results by the CFIA, which could take several
weeks.
Quick voluntary action on issues of a fish health nature is a standard operating
procedure for Cooke Aquaculture and these measures go above and beyond
regulatory requirements. These actions are viewed as extremely positive and
proactive measures in terms of animal welfare and virus control.
The suspect fish will not be sold for human consumption even though they pose
no human health risk. They have been disposed of in an approved manner in
compliance with the Province of Nova Scotia and CFIA

Canadian government is 'muzzling its scientists'
By Pallab Ghosh
 
Science correspondent, BBC News, Vancouver
  
The Canadian government has been accused of "muzzling" its scientists.

Speakers at a major science meeting being held in Canada said communication of vital research on health and environment issues is being suppressed.

But one Canadian government department approached by the BBC said it held the communication of science as a priority.

Prof Thomas Pedersen, a senior scientist at the University of Victoria, said he believed there was a political motive in some cases.

"The Prime Minister (Stephen Harper) is keen to keep control of the message, I think to ensure that the government won't be embarrassed by scientific findings of its scientists that run counter to sound environmental stewardship," he said.

I suspect the federal government would prefer that its scientists don't discuss research that points out just how serious the climate change challenge is."”

 "I suspect the federal government would prefer that its scientists don't discuss research that points out just how serious the climate change challenge is."

The Canadian government recently withdrew from the Kyoto protocol to reduce carbon dioxide emissions.

The allegation of "muzzling" came up at a session of the AAAS meeting to discuss the impact of a media protocol introduced by the Conservative government shortly after it was elected in 2008.

The protocol requires that all interview requests for scientists employed by the government must first be cleared by officials. A decision as to whether to allow the interview can take several days, which can prevent government scientists commenting on breaking news stories.

Sources say that requests are often refused and when interviews are granted, government media relations officials can and do ask for written questions to be submitted in advance and elect to sit in on the interview.

'Orwellian' approach

Andrew Weaver, an environmental scientist at the University of Victoria in British Columbia, described the protocol as "Orwellian".

 The protocol states: "Just as we have one department we should have one voice. Interviews sometimes present surprises to ministers and senior management. Media relations will work with staff on how best to deal with the call (an interview request from a journalist). This should include asking the programme expert to respond with approved lines."

Professor Weaver said that information is so tightly controlled that the public is "left in the dark".

"The only information they are given is that which the government wants, which will then allow a supporting of a particular agenda," he said.

The leak was obtained and reported three years ago by Margaret Munro, who is a science writer for Postmedia News, based in Vancouver. Speaking at the AAAS meeting, she said its effect was to suppress scientific debate on issues of public interest.

"The more controversial the story, the less likely you are to talk to the scientists. They (government media relations staff) just stonewall. If they don't like the question you don't get an answer."

Ms Munro cited several examples of what she described as the "muzzling" of scientists by the government.

 
Research on falling salmon stocks was published in a leading journal The most notorious case is of that of Dr Kristi Miller, who is head of molecular genetics for the Department for Fisheries and Oceans. Dr Miller had been investigating why salmon populations in western Canada were declining.

The investigation, which was published in one of the leading scientific journals in the world, Science, seemed to suggest that fish might have been exposed to a virus associated with cancer.

The suggestion raised many questions, including whether the virus might have been imported by the local aquaculture industry.

Requests denied

The journal felt this to be an important study and put out a press release, which it sent out to thousands of journalists across the world. Dr Miller was named as the principal contact.

However, the government declined all requests to interview Dr Miller. It said it was because she was due to give evidence to a judicial inquiry on the issue of falling fish stocks.

According to Ms Munro, because reporters were denied the opportunity to question Dr Miller about her work, important public policy issues went unanswered.

"You have a government that is micromanaging the message, obsessively. The Privy Council Office (which works for the Prime Minister, Stephen Harper) seems to vet everything that goes out to the media," she said.

A spokeswoman for Fisheries and Oceans Canada told BBC News: "The Department works daily to ensure it provides the public with timely, accurate, objective and complete information about our policies, programmes, services and initiatives, in accordance with the Federal Government's Communications Policy.

"In 2011, Fisheries and Oceans publicly issued 286 science advisory reports documenting our research on Canada's fisheries; our scientists respond to approximately 380 science-based media calls every year."

Fisheries and Oceans Canada declined a request by the BBC to interview Kristi Miller for this article. Dr Miller told us she would have been willing to be interviewed had her department given her permission.

The AAAS meeting's discussion on muzzling is organised by freelance science reporter Binh An Vu Van. She says fellow journalists across Canada are finding it "harder and harder" to get access to government scientists.

Ms Vu Van claims that as well as "clear-cut cases of muzzling", such as the one involving Dr Miller, media relations officers use more subtle methods. She said that when she requests an interview, she has to enter into prolonged email correspondence to speak to a scientist she knows is ready and willing to be interviewed, often to be declined or offered another scientist she does not want to interview.

"It's so hard to get hold of scientists that a lot of my colleagues have given up," she explained.

Ms Munro cited another example of research published in another leading scientific journal, Nature, that was published last October.

You have a government that is micromanaging the message, obsessively. It seems to vet everything that goes out to the media”

 An international team including several scientists from the government agency, Environment Canada, set out details of a hole that appeared in the ozone layer above the Arctic.

Ms Munro said she had called one of the scientists involved who she had dealt with several times in the past. He agreed to speak to her, but said that he had been told that her request had to be put to government media relations officials in Ottawa.

"So I phoned up Ottawa and they just said no you can't talk to the guy. A couple of weeks later, he was available but by then the story had been done. So they take them out of the news cycle," she said.

Ms Munro also claims that journalists were denied access to scientists working for the government agency Health Canada last year, when there was concern about radiation levels reaching the country's western coast from Japan following the explosion at the Fukushima nuclear power plant. Ultimately, journalists obtained the information they sought from European agencies.

The Postmedia News journalist obtained documents relating to interview requests using Canada's equivalent of the Freedom of Information Act. She said the documents show interview requests move up what she describes as an "increasingly thick layer of media managers, media strategists, deputy ministers, then go up to the Privy Council Office, which decides 'yes' or 'no'".

"The government has never explained what the process is. They just imposed these changes and they expected us to sit back and take it," she explained.

Professor Andrew Weaver believes that the media protocol is being used by the Canadian government to "instruct scientists to deliver a certain message, thereby taking the heat out of controversial topics".

He added: "You can't have an informed discussion if the science isn't allowed to be communicated. Public relations message number one is that you have to set the conversation. You don't want to have a conversation on someone else's terms. And this is now being applied to science on discussions about oil sands, climate and salmon."

Re: Lethal virus from European salmon found in wild BC salmon

From Alex.

Two outbreaks of ISA virus - in Nova Scotia Cooke Aquaculture says it was found in a routine surveillance which means there were not any obvious losses, a situation I believe similar to BC. They call it "suspect" ISAv but they destroyed two pens. This is a big response to "suspect" ISA, but if they actually have it, is killing just 2 pens enough? What about the rest of the farm? We will see. In Norway ISA has appeared on their central coast and they are harvesting the fish, which suggests they are going for human consumption and emptying the pens will take as long as it takes to process all the fish. In BC we are still not allowed access to the farm salmon to confirm government's position that ISA virus is not in their fish.

We can understand why no one is willing to admit that ISA is here in BC....
