I am bringing together a number of posts on the issue of fish farms killing wild salmon. If anyone tries to tell you different, just refer them to this post.
1. Fish Farms Kill More than 50% of Wild Salmon. In the presence of fish farms, 50% of wild salmon die: http://fishfarmnews.blogspot.ca/2013/01/fish-farms-kill-more-than-50-of-wild.html.This meta-data analysis examined Scotland, Ireland, Atlantic Canada and BC.
2. Fish Farm Lice Kills 34% of Wild Salmon: http://fishfarmnews.blogspot.ca/2015/12/fish-farm-lice-kill-34-of-wild-salmonids.html. The experts from Norway, Canada and Scotlandm reviewed more than 300 studies.
3. Fish Farms Lice Kill Wild Salmonids, 2015 literature review: http://fishfarmnews.blogspot.ca/2015/09/fish-farm-lice-kill-wild-salmonids.html.
4. The Atlantic Salmon Federation, 2016, highlights science that fish farms kill wild salmon: http://asf.ca/letter-you-cannot-dispute-the-evidence.html. They point out that DFO itself has noted genetic problems with escaped farmed fish and wild Atlantics: "Last month, DFO scientists revealed the results of a new study that
confirmed widespread mating between wild salmon and aquaculture escapees
in 17 south coast rivers, which they believe has led to reduced
productivity and abundance in those populations."
And also that the greater amount of science on the subject is conclusive: "After many years and hundreds of studies, we are past debate over
whether or not aquaculture has negative impacts on wild salmon stocks"
