Norwegian salmon farming giant Cermaq has a salmon lice problem on their Clayoquot Sound salmon farms. Documents released through Access to Information indicate Cermaq obtained an Emergency Drug Release to use the insecticide Lufenuron to control salmon lice in the Clayoquot Sound UNESCO Biosphere Region.
Last year saw salmon lice numbers in Clayoquot spike to levels never before seen in British Columbia, up to 55 lice per farmed fish—eighteen times the threshold for treatment set out by Department of Fisheries (DFO). Independent monitoring found wild salmon juveniles had lice counts as high as 50 per fish.
Cermaq is unable to control their salmon lice epidemic in Clayoquot Sound. Their 2018 lice outbreak likely devastated last year’s wild salmon cohort, and their 2019 numbers are already up to 5 times the DFO limit, right at the beginning of the wild salmon out-migration window. Continue reading →
The call came in at the end of a busy day last week: ‘Cermaq is experiencing a mass die-off at two of their farms in Clayoquot Sound’. By early morning the next day we had assembled a volunteer boat driver and photographer, sourced a donated water taxi, and raised the funds to fuel the boat and hire a videographer complete with drone. We set off in anticipation.
The first farm we got to didn’t seem to have any unusual activity, other than the whole Herbert Inlet was a weird murky turquoise. An employee boated over to photograph us, and a polite exchange followed. ‘We’re not sure what this colour is’, he said. ‘We’ve been seeing it for six weeks—could be Chryso’ (shorthand for Chrysochromulina, a species of algae).
The second farm we reached was the Millar Channel farm, just kilometres north of the site evicted by Ahousaht First Nations, after it was occupied by the Yaakswiis Warriors last September. There was a hum of activity: workers tossing dead salmon into totes, which were lifted and dumped into semi-trailers designed to haul away animal remains. The tubes sucking the dead fish (morts) from the pens were getting plugged up with the sheer numbers, and divers were in the pens unplugging them. Continue reading →
