In the U.S. state of Wyoming there are about 4,200 lakes (with over 333,000 acres (1,348 km2) of water) and over 27,000 miles (43,000 km) of fishable streams.
Wyoming game fish include bass (Micropterus and Ambloplites); sunfish (Lepomis); crappie (Pomoxis); walleye and sauger (Sander); yellow perch (Perca); trout, salmon, and char (Salmo, Oncorhynchus, and Salvelinus); whitefish (Prosopium); grayling (Thymallus), pike (Esox); catfish and bullheads (Ameiurus, Ictalurus, Noturus, and Pylodictis), burbot (Lota); sturgeon (Scaphirhyncus); and freshwater drum (Aplodinotus).
Threats to Wyoming game fish include the New Zealand mud snail, the common carp, and whirling disease.
In addition, the introduction of brook sticklebacks (Culaea incontans), walleyes, ling suckers, and white suckers have impacted the ecology of native game fish.
Conservation efforts to protect Wyoming game fish include licensing, creel limits, and issuing conservation stamps.
