yes - in the Atlantic - quite a bit of proof: IPN, ISA, PRV, parasites, etc. In the Pacific - CFIA still claims the weak positives are "false" positives - for the reasons outlined earlier in this thread. This despite the viruses found being closely related to the Norwegian strains. No big mystery how that happened.the question is not does or doesn't the fish farm have disease. any animal that lives in close quarters to one another is going to spread disease onto one another. the accusations are that fish farms spread disease onto wild stocks. i'm just asking if there is any proof of this..
