this past summer we got a few reds where the belly was torn up pretty bad. We saved them and tried them for Halibut. They were by far the best bait we have ever used. The would not touch the cod or pollock. We also never got a touch on the octopus we tried. we caught one and cut up part of a leg for bait. Herring was ok but they just pounded the bellies. a belly also lasted for more than one fish. they stayed on the hook forever. the only bad part is that its the best part on a salmon. On the grill or on the smoker you just cant beat them. As good as they are for bait i just could not bring myself to use them for bait when i can eat them. we also dug some out of the fish cleaning barrels. I cant see why anyone would throw the best eating part away. What is your favorite bait for Butts?
