BigJoe's tip

'No black, put it back' — bull trout have no black spots and no black on the dorsal fin.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Grizzly and black bear country — carry bear spray.

Regulations

Listed as threatened in the lower 48 U.S. states; nearly all waters are closed to harvest, and some to targeting. Canada also protects many populations. Learn to tell it from brook trout and lake trout. Licenses, limits and seasons are set by each province, territory or state, and many lakes and rivers have special size limits, slot limits or closed spawning seasons — check the current regulations for the water you fish.

Conservation

Dams, warming water and competition from brook trout hurt bull trout across their range.
