Pretty sure its massive commercial fishing outfits that are primarily to blame. Sea lice might have a small effect but nothing compared to what the large scale commercial fishing operations do.If you don't believe me take a look in your local supermarket or your nearest Red Lobster and then times what you see by 1000000 cuz those wild salmon products span several different chain supermarkets and restaurants.Whether the damage done is during the targeting of certain species or from by-catch its debatable.
When will they classify salmon as endangered ? When there is only a dozen left ? Is it too late already ?
