Whales are probably one factor. It takes a lot of food to support a whale, which will reduce the fish available. There's probably more than one factor causing this. It will probably take action in more than one way to fix this problem.
Salmon (except landlocked) were all but wiped out in Vermont, in the 1800's by damming of rivers. But they were still abundant in Maine for a long time. Even now with considerable effort to let them come to our rivers few are returning here each year. Why? It's still being studied. And with Maine's salmon...there's more at play.
