Stocked as a predatory fish to control suckers, these tiger muskies will provide an exciting challenge for anglers

Laramie - Although they are not yet the legal size of 36 inches for anglers to keep, tiger muskies in Upper North Crow Reservoir are getting big. The Game and Fish Department began stocking tiger muskies into Upper North Crow Reservoir in 2015 as a biological control to reduce the numbers of longnose suckers and white suckers. The tiger muskellunge (muskie for short) is a piscivorous fish, or one that eats other fish, and is the sterile hybrid offspring of the true muskellunge and the northern pike. Trout stocking was discontinued at Upper North Crow Reservoir to encourage the tiger muskie to feed on the suckers.
Sucker abundances have decreased since 2015 and so future management aims to resume stocking trout in 2020 as well as additional tiger muskies every third or fourth year as a predator for suckers. Trout stocking will include larger-sized fish that will be less susceptible to predation by tiger muskies.
Fish managers say tiger muskies are difficult to catch but will prove to be an exciting challenge for the determined angler. This particular fish measured 24.6 inches and weighed 3.9 lbs.
