What is being done to ensure that the Native Americans at the hatchery trim the dorsal fin of the salmon and steelhead?
Answer:
Fish released from native American hatcheries aren't required to have their adipose fin clipped - but they do clip a portion to help differentiate the released fish as "hatchery origin." The reason some of the hatchery fish are not clipped when they are released is to make sure enough adult return to a trapping site to assure there are plenty of brood stock for future generations. Numbers and release sites are coordinated with other regulatory agencies.
