The Idaho Department of Game and Fish will investigate bait hooking mortality rates for wild Yellowstone cutthroat trout and rainbow trout when using circle hooks versus traditional hook types in river systems. Project will quantify the risk of allowing bait fishing in streams supporting native trout fisheries when captured using flies, lures, traditional J hooks with bait, and circle hooks with bait. Implicit in wild trout fisheries is the survival of fish released after capture. Gear types often affect survival of released trout. This project will enhance wild trout populations managed with special fishing regulations by helping managers institute appropriate gear restrictions. Project partners include local landowners and students.
