DFO Decision: Discovery Island Fish Farms remain closed

According to the Fisheries and Oceans (DFO) press release of February 18, 2022, “There are multiple stressors on wild salmon, including: climate change; habitat degradation and destruction; regulated fishing as well as illegal, unreported, and unregulated fishing. Given the state of Wild Pacific Salmon, the Government of Canada is taking a highly precautionary approach to manage Atlantic salmon aquaculture in the Discovery Islands area.”

Licenses for the 15 remaining fish farms in this region will not be reissued.

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.

Countdown for 79 salmon farms: new report says sea lice have developed resistance to SLICE

On Monday a new study confirmed what environmentalists have been saying for years, sea lice have developed a resistance to SLICE the treatment fish farms most often use against them.

The BC Salmon Farmers Association new ‘independent’ sea lice report 

The opinions that follow belong to the people expressing them and are not necessarily shared by Cortes Radio, its board, staff, producers or listeners.

The BC Salmon Farmers Association has just released what they claim is an independent study of ‘Sea lice in the Discovery Islands.’ 

Their study is filled with terms like – “independent data,” “independently collected data,” “independent professional biological consultants,” “independently collected and analyzed scientific data,” “independent monitoring,” “independent sampling,” and “independent biologists” – but does not say who actually did the research.

Fish farms underreport sea lice when not being audited, study says

1 Comment

“Our results suggest that sea-louse counts reported by the salmon farming industry are lower than the true abundance of parasites on their fish. When the federal government audited a sea-louse count, the industry’s mean counts for that month increased by a factor of 1.18 for L. salmonis and by 1.95 for C. clemensi.” – Sean Godwin et al, Bias in self-reported parasite data from the salmon farming industry.

Dr Sean Godwin is the lead author of eight of the fifteen scientific papers listed on his website. The bulk of these explore interactions between wild and farmed salmon. One of the most troubling, published in the journal Ecological Application, is a survey that showed fish farms underreport sea lice when they are not audited by Fisheries and Oceans Canada.
