New Study on Impacts to Wild Fish from Salmon Farms

Thursday, 11th January 2018

A new report, commissioned by Salmon & Trout Conservation Scotland, tells a damning story about the impacts of salmon farms on wild salmon and sea trout. The first paragraph of the abstract reads

Results from scientific studies on the impacts of salmon lice on Atlantic salmon and sea trout are summarized [here]. Considerable evidence exists that that there is a link between farm-intensive areas and the spread of salmon lice to wild Atlantic salmon and sea trout. Several studies have shown that the effects of salmon lice from fish farms on wild salmon and sea trout populations can be severe; ultimately reducing the number of adult fish due to salmon lice induced mortality, resulting in reduced stocks and reduced opportunities for fisheries. Depending on the population size, elevated salmon lice levels can also result in too few spawners to reach conservation limits.

Damning indeed. The full report is available here
