While bluefishing, was talking to a hunter that he takes the whole bluefish and uses it for bait. I didn't ask him Where he hunts, but IF you were allowed to bait, I guess that would be adequate and cheap. When we finished bluefishing, he kept about 10 whole fish and freezes em. Not too many people were keeping theirs, just a couple filets. For me, it's not the best tasting fish. Maybe any kind of fish will do ?
