Canada: Salmon farms do not impact sea lice levels on wild fish

Tridge summary

A recent study published in the Reviews in Aquaculture journal challenges the claims by activists that sea lice from salmon farms are causing a decline in wild salmon populations. The research, which examines regulatory management of salmon farming in Norway, suggests that there is no measurable impact of sea lice infections from farms on wild salmon. This finding is in line with Canadian government research and supports the idea that there are other factors contributing to wild salmon survival. The study's authors call for a broader understanding of the issue and criticize the government's decision to ban open-net salmon farming in British Columbia, which they argue is not supported by science.

New study and data counters the continued exaggeration by activists that wild fish populations are declining due to sea lice from salmon farms. By Fabian DawsonSeaWestNews A new and extensive literature review is challenging the assertions by activists that sea lice from fish farms significantly affect wild salmon populations. The study, published in the journal Reviews in Aquaculture, examined the regulatory management of salmon farming in Norway and found no measurable impact of sea lice infections from farms on wild salmon. This aligns with Canadian government research which found that sea lice on farm-raised salmon do not impact sea lice levels on wild juvenile salmon in British Columbia. The main findings of the new review are that: Simon Jones, Emeritus Scientist at Fisheries and Oceans Canada (DFO) and co-author of the study emphasized the need for a broader understanding of factors affecting wild salmon survival. “This is an important finding, as it aligns with the ...
