(c) Any fish caught that is not to be counted in the creel limit shall be immediately released to the water with as little injury to the fish as possible.

When length limits apply, the whole body shall remain intact (gills and entrails can be removed) while in transit or in the field. Where length limits do not apply, a piece of skin large enough to allow species identification (at least one (1) inch square) shall remain on all fish fillets while in transit or in the field, except as otherwise provided in Sections 22, 25 and 32 for walleye and sauger harvested in the Wind River, Big Horn River and Tongue River drainages and Glendo Reservoir and in Section 28 for lake trout harvested in Flaming Gorge Reservoir.
(e) There are no creel or possession limits on nongame fish. Nongame fish may be taken by the use of legal fishing methods during any season open for the taking of game fish.
