jw - your situation of too few forage fish is a common problem. Adding more forage is the same as having a bunch of, or actually, too many wolves in an enclosure or on an island. To fix it you want to add more sheep and deer to feed them. This makes the wolves healthier so they produce more wolves.
Bill are you sure your statement came out the way you wanted it to?
I figured the corrective method would be to reduce the wolf population so the sheep and deer could get established for a more balanced food source.
Or maybe I just read and took your statement incorrectly?
