They need to back up and start by getting the Menhaden situation under control - instead of inventing problems in other (healthy) fisheries.
Interesting article on the subject:

Now I don’t agree with all this article says, but I do believe Atlantic Menhaden are seriously overharvested - which causes ripple effects on all sorts of other fisheries.
