Species Characteristics

Long and cylindrical body, usually olive-gray. The back is crossed with 3 to 4 dark saddles, which extend down the sides. The white color of the belly extends to the tip of the tail, but the coloration does not spread out at the end of the tail and form a definite white tip as it does on Walleye. There are 2 or 3 rows of black dots on the first dorsal fin and a large black blotch at the base of the pectoral fin. There are 17 to 19 rays in the dorsal fin and 11 or 12 in the anal fin. The lateral line has 85 to 91 scales. About 15 rows of scales cover the cheeks. It does not reach the size of Walleye, seldom exceeding 2- to 4-pounds.
