North and Central America: Mississippi River basin from central Indiana and Illinois in USA south to Gulf of Mexico and Gulf Slope drainages west to Mexico. One of the species with the widest range of introductions which acquired for itself a near pan-global distribution (Ref. 1739). Several countries report adverse ecological impact after introduction.

deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 7-9; Duri dubur 0; Sirip dubur lunak: 9 - 10. Origin of dorsal fin opposite 7th anal ray.

Biologi     Daftar kata (contoh epibenthic)

Most abundant in lower reaches of streams (Ref. 44091). Adults inhabit standing to slow-flowing water; most common in vegetated ponds and lakes, backwaters and quiet pools of streams. Found frequently in brackish water (Ref. 5258). Pelagic and surface predatory fish (Ref. 94816). Feed on zooplankton, small insects and detritus (Ref. 5258, 10294). Used as live food for carnivorous aquarium fishes. Viviparous (Ref. 5258, 30578). Effective in mosquito control and widely introduced, but found to compete with indigenous fish and to upset the ecological balance (Ref. 6351).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

The species is viviparous (Ref. 5258). Internal fertilization is possible because the anal fin of the male is modified into a copulatory organ. The females carries about 30 alevins and gestation lasts for a period of 24 days (Ref. 6348) to a month (Ref. 30578).
