Sounds like feeding the bast*rds, then dropping a CROC LINE with meat on hooks strung on the bottom to drown 'em may get some of the bast*rds. Read somewhere were someone did something like that to thin 'em out. They are at the top of the food chain and no way to control them naturally.

Of course I would never do such a thing as it would be illegal-

Still got no use for the evil SOB's-
