A new UC Davis study concludes that sea lice from salmon farms have no significant impact on the productivity of wild pink salmon populations. The research analyzed 10 years of farm fish counts and 60 years of wild fish counts, contradicting earlier reports linking farm salmon to the 2002 population crash in western Canada.
