Before the Standing Committee on Fisheries and Oceans: Was DFO’s ‘minimal risk’ assessment a cover-up?

At the May 12 session of the Standing Committee on Fisheries and Oceans, Stan Proboszcz, senior scientist at the Watershed Watch Salmon Society suggested that DFO covered-up some of its own research when it concluded fish farms pose ‘minimal risk’ to wild salmon. He said they appear to have reduced the number of science risk assessments from 10 to 9 because the evidence indicated sea lice harm wild sockeye.

47 days until a decision must be made: sea lice and pathogens

As we get closer to June 30, when the Department of Fisheries and Oceans (DFO) has to decide whether to reissue the licenses for 79 British Columbian salmon farms, independent biologist Alexandra Morton points to yet more problems. 

A recent Global and Mail article revealed the existence of a decade old Department of Fisheries (DFO) report about the ‘transmission of the PRV virus from farmed to wild salmon.’

Morton said the fish farm industry has exceeded the three lice per fish threshold every week since the out-migration season began on March first. Two to five active farms have exceeded that limit every week, for the past five weeks. Morton claims that no sooner had the industry brought the lice on one farm under control, than another exceeds the limit.

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

“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.
