Rock bass across North Carolina

“A member of the sunfish family, the rock bass has a short, robust body with an olive-green top and gold or brassy-colored sides. The scales along its sides have a dark spot, often forming a striped-like appearance. The anal fin has five to seven hard spines, and on adult rock bass, this fin has a dark outline. There is a dark spot on the ear flap, and the cheeks are scaled. The Roanoke bass, found with rock bass in some rivers of the northern Piedmont, is similar in appearance but does not have cheek scales or a dark margin on the anal fin. The warmouth is also similar in appearance to a rock bass but has only three hard anal spines.”

“Rock bass are native to the Mississippi River drainage and northern Atlantic drainages, such as the Connecticut and the Delaware rivers. In North Carolina, rock bass are native to rivers in the western part of the state that flow to the Mississippi, and they have been stocked into numerous rivers draining to the Atlantic Ocean. Rock bass are usually found near sheltered pool areas around rocks and woody debris in rivers in the mountains and foothills. They are occasionally found in lakes. Rock bass eat primarily aquatic insects, crayfish and small fish.”
