The weak sources you listed are WEBSITES - NOT academic literature - from salmon farming industry proponents, funded by Marine Harvest, Grieg, Cermaq, and likely other aquaculture conglomerates. Of course they are going to have a bunch of tripe on the internet denouncing the science and refuting all claims to the contrary of their industry. It would be suicidal for a business to not act in self defense if their money-making machines are being threatened to be shut down. There is no big room with a round table with devious scientists plotting the collapse of the fish farming industry so that Alaskan wild fish increase in value. This is hogwash, and you're beating around the bush by not outright declaring that is what you believe in. It's conspiracy-theorist nonsense.
The farm fresh salmon website is handled largely by Cory Percevault, Plant Manager at Noboco’s Coulter Road plant in Campbell River. Would it make sense for Mr. Percevault to potentially lose his job by not defending it? It's a cut-throat world. I imagine you've spent time working on the farms and have pent up resentment about the anti-farming activists and all these ridiculous references you're citing are your way of helping yourself sleep at night. Rationalize it to yourself all you want if it makes you feel better, but don't go spewing your corporate rhetoric as if it were even remotely honest and true because it's not. It's unscientific and completely dishonest.
Think for yourself, just like many of the independent scientists whose research indicates ecological problems with aquaculture. Many of these scientists were funded by NSERC (Natural Sciences and Engineering Research Council), which is about as independent as it comes.
