SADLY YOU CAN THROW FISH GUTS BACK IN LAKE IN UTAH BUT YOU CANT USE THEM AS BAIT... NO GAMEFISH PARTS ALLOWED AS BAIT !!I want to tell you all the best crawdad bait for your traps I found quite by accident. It was the first Lake Trout I caught since moving to Co, some 35 yrs ago. We were camping for the weekend with half the town of Ridgway, at Mira Amonte Lake . Having never eaten a lake trout I took it with us. After filleting I had the carcass of backbones and skin. On a whim I broke it down and put it in 2 traps I had. When I retrieved the traps I was amazed because they were both stuffed and actually hanging on the outside of the trap. I found I wasn't to keen for the oily strong flavor of lake trout! But its the best crawdad bait I have ever found! Makes sense because its fatty and oily and milks well in the water. Try it..
Crawfish get all over the entrails and guts, they love them but Illegal to bait a trap with them.
