I can see only two ways to stop the fish farms from polluting: a crash in the financial market so huge that the exports stop, or encouraging artisan fishing with small fishing vessel to offer the people that work at this farms a better deal – make small fishing cooperatives – get the cooperatives to buy boats, educate the Fishing cooperatives to fish sustainable, when business become big the people investing in them become greedy and they forget anything else, nothing matters just to keep making profits
