Canada: Activists distort data to attack B.C. salmon farmers

Published 2024년 11월 21일

Tridge summary

Anti-fish farming activists in British Columbia are spreading misinformation about the impact of salmon aquaculture on wild salmon populations, claiming that the removal of salmon farms leads to a decrease in sea lice and an increase in wild salmon numbers. However, data from the Broughton Archipelago and other scientific sources, including the Canadian Science Advisory Secretariat and a comprehensive literature review from Norway, contradict these claims, showing no significant impact of sea lice from salmon farms on wild juvenile salmon. The activists' claims are criticized for oversimplifying complex ecological dynamics and ignoring other factors such as ocean temperature, overfishing, and habitat degradation, which have a greater impact on wild salmon. The British Columbia Salmon Farmers Association is using the most up-to-date science, including traditional ecological knowledge from First Nations, to address these misconceptions and continue operating in a way that benefits both wild salmon and rural communities.

By Fabian Dawson SeaWestNews Anti-fish farming activists have long weaponized misconceptions to vilify salmon aquaculture, and the recent high returns of wild salmon in some British Columbia rivers have become another tool in their arsenal. By oversimplifying complex ecological dynamics, they perpetuate the myth that “when salmon farms are removed, sea lice numbers drop, and wild salmon populations numbers rise.” Years of continuous data collection on sea lice and wild stocks near salmon farms shows this isn’t true, said the B.C. Salmon Farmers Association. In the Broughton Archipelago, where salmon farms were removed under a phased withdrawal between 2019 and 2023, newly released data points to the activists twisting the facts to fit their agenda. The 2024 data from the Broughton Archipelago wild juvenile salmonoid monitoring program illustrates that salmon farms do not drive sea lice levels on wild salmon, as the variability in the percentage of sea lice on wild Pacific salmon ...
