Bass Fishing: Rock Bass
AKA: Redeye, redeye bass, goggle eye, rock sunfish
This species of freshwater fish is not really a bass, but a member of the sunfish family, associated with bass because of its rocky habitat.
Rock bass have a very deep and laterally compressed body. They usually have red to orange eyes, large, terminal mouth, body coloring from golden brown to olive, with white to silver belly, and 5 to 7 spines in the anal fin and 12 in the dorsal. Rock bass are less colorful than the bluegill, but have the ability to rapidly change its color to silver or blackish to match its surroundings.
About 6 to 8 inches and weighing less than a pound.
Rock bass can be found in all the Great Lakes and Saint Lawrence River system, Wisconsin, the upper and middle Mississippi River, and down to Missouri, northern Alabama and Georgia in the south, as well as from Québec to Saskatchewan in Canada.
Rock bass prefer clear, vegetated and rocky lake margins and stream pools. Their favorite habitat is clear, cool to warm waters, with gravel or rocky bottoms, and some vegetation. Rock Bass species are usually found near stone-armored shorelines and breakwaters.
Rock bass species are carnivorous, eating insects, crustaceans and smaller fish and crayfish. Adult Rock bass may eat heavily, particularly in the evening and early in the morning. Younger species become food for larger predatory fish such as northern pike, muskellunge and large bass.
Rock bass mature in three years can live as long as 10 years. Spawning occurs from April to early June in warm waters ranging from 55 to 60 degrees F., with females laying from 2,000 to 11,000 eggs. Males can become aggressive defending their territory while they attract and hold females.
