It's not that fish farms are my interest. It's that I lived in a territory that the fish farms moved into and then I studied the impact of that. I think hatcheries are a serious problem. I think disease testing should be upped in those hatcheries.
As for the pinnipeds, removing the predators has never helped to release the prey, except maybe in very specialized situations, like what is probably happening in the Columbia River and other rivers in our area. You have to be very careful. If you remove the animal that is eating the hake, for example, and the hake prey heavily on juvenile salmon, you can actually have a reverse impact. These are questionable ways to go forward.
