Canada's salmon farming industry over the past year has taken activists to task over claims that British Columbia's (BC) netpen salmon farms harm wild salmon.

It was through a carefully worded email sent to Pattison Media -- Canada's largest private western-based radio and television company and a division of the CDN15 billion ($10.8 billion/€10.1 billion) Jim Pattison Group -- that the BC Salmon Farmers Association (BCSFA) won a revision to an ad from the NGO Wild First  that initially stated "Canada must protect wild Pacific salmon by removing all ocean-polluting salmon farms."
