Idaho Fish and Game

Watch for Bull Trout This Season

idfg-staff
Anglers need to keep an eye out for bull trout, a fish native to most Idaho's clearest waters, as the general fishing season begins May 29. Bull trout are listed as threatened under the federal Endangered Species Act and are strictly protected by federal and Idaho law. These fish must be returned immediately and unharmed to the water whenever they are caught. Anglers unfamiliar with bull trout can see it pictured in color in the Idaho fishing rules brochure. Most areas where bull trout are likely to be encountered have signs that show the fish. Anglers are responsible for knowing the species they are catching. Bull trout is the only trout-like species in Idaho that has no spots or markings on its dorsal (back) fin. Be safe. If you don't know, let it go. The minimum fine for the illegal killing of a bull trout is $250 and it can be more depending on the case. A loss of fishing privileges for up to three years is also possible. Senior conservation officer Marshall Haynes said officers in Idaho's most populous region, the Southwest, will be emphasizing bull trout this season. Special attention will be on the Boise river drainage from Lucky Peak and Arrowrock reservoirs upstream. That includes waters on the Middle Fork and North Fork of the Boise River as well as the South fork of the Boise River including Anderson ranch reservoir.
