Study: Salmon Farms Reduce Wild Pink Salmon Numbers
There’s been plenty of hemming and hawing about claims that salmon farms harm wild fish, but an extensive study released Monday by the American journal Proceedings of the National Academy of Sciences seems to prove that putting penned salmon in the migration path of juvenile fish is a bad idea. “‘The basic physics says this result should not be surprising,’ said Neil Frazer, a professor of physics at the University of Hawaii who worked on the mathematical modeling that went into the study. ‘When you put a bunch of farmed fish into a system of wild fish and parasites, you automatically are going to greatly increase the number of parasites, because you now have a much better chance of finding a host.'” AP’s Jeff Barnard in the Houston Chronicle.
