Fisheries and Oceans Canada faces deluge of calls to improve ‘suspect’ science

Canada’s National Observer, Local Journalism Initiative Reporter

The Department of Fisheries and Oceans is being flooded with calls for change after a parliamentary committee examined how the federal agency conducts, interprets and acts on its own science. 

The investigation ended with 49 recommendations to address concerns about how DFO science is presented to the fisheries minister and the public before important political decisions are made — particularly those involving B.C. salmon farms or commercial fisheries on either coast.

Report of the Standing Committee on Fisheries and Oceans

Originally published by the Parliament of Canada

On 1 February 2022, the House of Commons Standing Committee on Fisheries and Oceans (the Committee) agreed to undertake a study to “examine how the Department of Fisheries and Oceans prioritizes, resources and develops scientific studies and advice for the department, how the results of scientific study are communicated to the Minister and Canadians, and how the minister applies data and advice provided by the department and other government departments to ministerial decisions.”The Committee heard from 57 witnesses over nine meetings held between 26 April 2022 and 7 October 2022.

16 scientists condemn ‘scientific failings’ of ‘flawed’ DFO report

Editor’s note: The following article is joint letter to the Honourable Joyce Murray, Minister of Fisheries, Oceans and the Canadian Coast Guard

Academic scientists’ critique of DFO Science Response Report 2022/045

Dear Minister,

We are a group of 16 professors and research scientists who, collectively, have extensive research expertise in fisheries, epidemiology, and the environmental consequences of aquaculture. We write to express our professional dismay at serious scientific failings in a recently published DFO Science Response Report (#2022/045) about sea lice on salmon farms and wild salmon in BC. We are deeply concerned with the report’s flaws and its main, unsupported conclusion: that the presence of parasitic sea lice on wild juvenile salmon is not significantly associated with sea lice from nearby salmon farms.

Tussle over sea lice science unfolds as a federal decision on Discovery Islands salmon farms looms

National Observer, Local Journalism Initiative Reporter

Critics and supporters of West Coast fish farms are at odds over a recent Fisheries and Oceans Canada (DFO) study suggesting sea lice infestations among juvenile wild salmon aren’t strongly tied to aquaculture operations. 

Using industry-reported data, the aquaculture division of DFO analyzed the likelihood that sea lice from salmon farms are causing sea lice outbreaks in wild fish in four areas on the coast.  

There’s a trend showing a positive relationship between the amount of sea lice on farms and on juvenile chum and pink salmon in those areas between 2016 and 2021, but it’s “statistically insignificant,” the study said.

70% of the fish farms sampled had PRV-1, study finds

1 Comment

A new study published by the Canadian Journal of Fisheries and Aquatic Sciences, states that 70% of the samples taken from 56 fish farms had PRV-1.

One of the co-authors is independent biologist Alexandra Morton, who explained, “The study was my concept and I funded a lot of the analysis and did a lot of the sampling myself. It was truly collaborative with Clayoquot Action sampling the Farms in Clayoquot Sound. An extraordinary man, Dr. Neil Fraser from Powell River got in his speed boat and went to the central coast. The Wild Fish Conservancy down in Washington State, sampled farms there. So it was  a sustained effort by a lot of people, and then Dr. Gideon Mordecai did the analysis of the relationship between the different strains that we picked up.”
