Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Remote country: bears, cold water and long distances from help.

Regulations

Alaska and the Canadian territories set limits; the Kobuk has trophy rules. Check local rules. In Alaska, rules are set by the Alaska Department of Fish and Game (adfg.alaska.gov); in Canada, by each province and territory. Many trout and char waters are single-hook, artificial-lure or catch-and-release only — check before you go.

Conservation

Slow growing; release the big breeders.
