Wonder what they do with the catch. If they are as good eating as any lakers we consumed, it seems there would be a market for canned lakers. They outta be at least as good as farmed salmon....and not nearly so controversial.
Ain't it just like humans, spend tons to try to eradicate or control something which has proven to have been detrimentally introduced into an environ which suits it (lakers in Yellowstone L and pike in Davis L) and we also spend tons to unsuccessfully try to retain fisheries in environs we have destroyed (salmonids on much of the west coast....Russian River).
