Anglers are more likely to catch hatchery than wild steelhead in the Snake River Basin, according to a study by a University of Idaho graduate student.

The student, guided by a professor with the Idaho Cooperative Fish and Wildlife Research Unit, documented catch-and-release mortality rates to be less than the 5% level assumed by state and federal fisheries officials. Both findings could help fisheries managers justify sometimes controversial recreational fishing seasons that target hatchery fish but also involve the handling of protected wild steelhead.
