Mass die off of salmon in fish farms, due to ‘toxic algae’ in British Columbia, Canada

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.
 
We observed the activity, documenting what was going on and taking video and photos. A fish farm boat then followed us to the Dixon Bay farm, which appeared to be dormant. Time to head back to Tofino to get the word out!
