Taxonomic Comments
Formerly in genus Chaenobryttus. Reported to hybridize with Lepomis cyanellus, and L. macrochirus. Though the gender of the name Lepomis is feminine (see Bailey and Robins, 1988, Bull. Zool. Nomencl. 45(2):100), the 1991 AFS checklist (Robins et al. 1991) retained the masculine ending for gulosus and other species, pending a vote by the ICZN on a petition (by Etnier and Warren) to treat Lepomis as masculine for nomenclatural purposes.

Range Extent Comments
Native to Mississippi River and Great Lakes basins from western Pennsylvania to Minnesota, south to the Gulf Coast; Atlantic and Gulf drainages from Rappahannock River, Virginia, to Rio Grande, Texas and New Mexico (Page and Burr 1991). Known from a couple locations in southwestern Ontario, Canada (Crossman et al. 1996). Introduced widely in western U.S., including lower Colorado River drainage, and in portions of Atlantic slope.
Occurrences Comments
This species is represented by a large number of subpopulations and locations.
Threat Impact Comments
Localized threats may exist, but on a range-wide scale no major threats are known.
Ecology & Habitat

Habitat

Ponds, lakes, swamps, and streams of low gradient with mud or debris over bottom; a pool species in streams where it often is near beds of vegetation or other cover; weedy turbid areas of rivers and backwaters. Tolerant of low oxygen levels of polluted waters. Common in lowlands, uncommon in uplands (Page and Burr 1991). Eggs are laid in a bowl-like nest made by male often in sand or rubble bottom with thin covering of silt or detritus near a rock, stump, clump of vegetation, or similar object, at depths of 15 cm to 1.5 m. Nests usually are separated from one another.

Reproduction

Spawns in spring and summer. Eggs hatch in 34.5 hours at 25-26 C. Sexually mature usually in 2nd or 3rd summer. Male guards and fans eggs. May spawn 2 or more times per season. See Moyle (1976), Becker (1983), and Sublette et al. (1990).
