There are conflicting ideas among experts as to whether the walleye is native to Montana or not. Regardless, it is one of the most important sport fishes in Montana's eastern drainage and elsewhere in the U.S. and in Canada, where the walleye is a much sought-after commercial fish as well. Its flesh is of the highest quality. In recent years some sportsmen's groups in Montana have aggressively pursued the increased planting of walleye and promoted walleye fishing tournaments. Sometimes walleye hybridize with sauger, producing sterile saugeye. Adult walleye largely eat fish and for the most part are lake and reservoir dwellers. Walleye are so named because of their large, reflective eyes which are very light-sensitive. They are very active at night.
Jaws and roof of mouth have large canine teeth. Anal fin has 2 spines and 11 to 14 (usually 12 or 13) soft rays. Body often has a golden hue.
