General Description: The elongate body is compressed from side to side, the upper jaw extends well beyond the rear edge of the eye in adults, the dorsal fin has two parts that are barely connected (front part is spiny and highest at the middle; rear part has soft rays), and the shortest spine in the dorsal fin is less than half as long as the longest spine. The overall color is silvery to brassy (brown in dark waters), with dark olive mottling; each side has a broad black stripe (continuous or broken into a series of blotches) that extends onto the snout. Maximum length is around 38 inches (97 cm).
Reproduction Comments: Spawning occurs mainly in spring or early summer after water temperatures have become sufficently warm. Spawning occurs mid-April to mid-June near the southern end of the range in Alabama, late April to early July near the northern range limit in Wisconsin. In Texas, spawning begins as early as February or as late as May, depending on water temperature. Eggs hatch in a few to several days, depending on water temperature. Males guard the eggs and hatchlings until the young bass disperse about a month after hatching. Individuals become sexually mature in 2-5 years, depending on growth rate, which increases with increasing temperature. See Moyle (1976), Becker (1983), and Scott and Crossman (1973).
Ecology Comments: May have small summer range or may wander widely (Moyle 1976). Young have strong schooling tendency (Becker 1983).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): BIG RIVER, CREEK, Low gradient, MEDIUM RIVER, Pool
Lacustrine Habitat(s): Deep water, Shallow water
Palustrine Habitat(s): FORESTED WETLAND
Special Habitat Factors: Benthic
Habitat Comments: Largemouth basses inhabit warm, quiet waters with low turbidity, soft bottoms, and beds of aquatic plants. Typical habitats include farm ponds, swamps, lakes, reservoirs, sloughs, creek pools, and river coves and backwaters. Many of the largest populations are in mesotrophic to eutrophic lakes or reservoirs. In lakes and reservoirs these fishes are usually close to shore. In general, they are in deeper water in winter than in summer.

Eggs are laid in shallow cleared depressions (nests) made by males in sand, gravel, or debris-littered bottoms, often at depths of 40-80 inches (1-2 meters) but up to at least 23 feet (7 meters) or as shallow as 8-12 inches (about 20-30 cm). Nests are often next to submerged objects and usually are more than 30 feet (9 meters) apart.

Adult Food Habits: Carnivore, Invertivore, Piscivore
Immature Food Habits: Carnivore, Invertivore, Piscivore
Food Comments: Fry feed mainly on zooplankton. Larger young eat insects, crustaceans, and fish fry. Adults eat mainly fishes, though sometimes prefer crayfish or amphibians (Moyle 1976, Smith 1979).
Phenology Comments: Largemouth basses may be active throughout most of the daylight hours and usually are relatively inactive at night and in winter; feeding is most intence near dawn and dusk in the warmer months.
Length: 70 centimeters

Economic Comments: Extensively cultured in U.S. since 1930s.

Population/Occurrence Delineation
Help
Group Name: Sunfishes (Centrarchids)

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Separation distance is arbitrary. Although members of this group vary in size and probably in typical movement distances, it is likely that even the smallest centrarchids occasionally disperse as far as do large centrarchids. Hence a single separation distance is used for all members of the family. Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.

Author: Hammerson, G.
Notes: Note that some species some species may at time be hard to detect. For example, nowhere is the Carolina pygmy sunfish known to be abundant. In addition, it is essentially an annual species, with adults dying soon after spawning, at an age of 12-15 months. In addition, young are so small that, for a several months, documentation of the species' presence at a particular locality might be almost impossible, at least without preserving specimens. Therefore, negative data at a known locality should be carefully interpreted (P. Shute).
