Utah Division of Wildlife Resources biologists and volunteers clip the adipose fins of Bear Lake cutthroat trout at the Utah State Fish Hatchery in Kamas on Friday. The fish will be stocked in Bear Lake later this spring, and the cut fins provide a visual way for biologists to identify which fish were raised in a hatchery. It also helps Bear Lake anglers know which cutthroat trout they are allowed to keep since they can only keep the hatchery-raised trout. Before the fins were clipped, the fish were anesthetized with clove oil. According to biologists, the fins typically heal within a day.
