Sea Lice Prevalent In Aquaculture Becoming Resistant To Pesticide; "Levels Never Seen Before" In BC

Who Could Have Predicted That?

Fisheries and Oceans Canada confirms the findings of independent research that says sea lice on salmon farms are becoming resistant to SLICE, a pesticide used to kill sea lice. It also confirms it is conducting a review of a Cermaq fish farm in Clayoquot Sound to determine whether the company properly followed the protocols for reporting and treating a sea lice outbreak in the spring.

Earlier this week, independent researcher Alexandra Morton and the Living Oceans Society published findings from research that highlights a sea lice outbreak earlier this year at a Cermaq salmon farm in Clayoquot Sound. The report, Lousy Choices: Drug Resistant Sea Lice in Clayoquot Sound, highlights the fact that sea lice are becoming resistant to SLICE, which is the only pesticide approved for sea lice control in Canadian fish farms.

“The spring of 2018 saw parasitic sea lice on both farmed and wild juvenile salmon in Clayoquot Sound reach levels never before seen in the province of B.C.,” the report states. It says DFO and the industry have known sea lice were becoming resistant to SLICE since 2014, but have “publicly and repeatedly denied this fact.”

According to the report, high levels of sea lice were found in both wild and farmed salmon in the Clayoquot Sound in the spring of this year. “Independent monitoring found 96 percent of wild juveniles carried lice, with an average of 8.04 per fish,” the report states.

That's pretty unfortunate. I like the natural predator idea Crutchez_CuiBono Nov 2018 #2

These floating fish pens gotta go. If we need to farm salmon that bad then take ‘em to land based tanks.

combined w the wash. Antibiotics seem to be failing an aging world. Dumping them in water in vast amounts can't be good.
The note in the comments that said that tiny (edit..Herring) was caught 20 km from a fish farm, is depressing. Good luck Canada. you are a beautiful country, and I'm honored to visit often. Keep your chins up.

That being said, I agree with BBG...the farms should be on land, not in the open ocean.

attributed to human action. Imo, it's irresponsible to continue the floating farm, off-shore cultivation practice. That's why gawd made things like petri dishes and fish tanks and best of all integrated recycling systems. The integrated systems are the most impressive and most logically appropriate to me.

Thanks for the post, hatrack.
