White Bass - Morone chrysops
The white bass is an introduced, recent, and infrequent resident of Montana found only in the Missouri River below Fort Peck Dam and the very lower end of the Yellowstone River. These fish are upstream migrants from Lake Sakakawea in North Dakota where they were stocked. They are characterized by a spiny dorsal fin and horizontal stripes. They are spring, broadcast spawners, seldom exceed 1 pound in weight, and of little consequence in Montana fishery management. In other states they are important game fish.
Silvery with six to nine dark, narrow stripes on side. Eye tinted with yellow.
