Largemouth Bass
Micropterus salmoides

Family: Sunfish family (Centrarchidae)

Other Names: green bass, green trout, slough bass

Description: dark green back, greenish sides often with dark lateral band; belly white to gray; large, forward-facing mouth; lower jaw extends to rear margin of eye

Habitat: shallow, fertile, weedy lakes and river backwaters; weedy bays and extensive weedbeds of larger lakes

Range: southern Canada through central U.S. into Mexico; widely introduced; warmwater fisheries in Colorado

Food: small fish, frogs, crayfish, insects, leeches

Reproduction: matures at 3 to 5 years of age; spawns when water temperatures reach 60 degrees, male builds nest in 2 to 8 feet of water, usually on firm bottom in weedy cover; female deposits 2,000 to 40,000 eggs, which the male fans and guards; eggs hatch in about 3 to 4 days; male protects fry until the “brood swarm” disperses

Average Size: 12 to 20 inches, 1 to 5 pounds

Records: State—11 pounds, 6 ounces, Echo Canyon Reservoir, 1997; North American—22 pounds, 4 ounces, Montgomery Lake, Georgia, 1932

Notes: The Largemouth Bass was introduced to Colorado in 1878. From the time it begins feeding, 5 to 8 days after hatching, it is an aggressive predator. Young bass eat tiny creatures such as copepods, waterfleas and insect larvae. Before the end of the first growing season, fish are added to the menu. Biologists estimate a bass must eat 4 pounds of forage to produce 1 pound of body weight. Largemouths are typically uncommon in depths greater than 20 feet, but clear-water western reservoirs can provide exceptions.
