Ecology
Habitat
Habitat Type: Freshwater
Comments: Pools, oxbow lakes, and deeper waters of large rivers; sometimes in backwaters and mouths of smaller rivers; reservoirs and lakes. Prefers clean to moderately turbid, deep, warm waters (Sublette et al. 1990). In Texas, habitats with abundant aquatic vegetation and silt bottom were most productive (see Sublette et al. 1990). Spawns in quiet pools, backwaters, flooded marshes and meadows. Eggs sink and adhere to objects.
Trusted
Migration
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
May sometimes migrate up small streams to spawn (Becker 1983)
Trusted
Trophic Strategy
Comments: Feeds opportunistically on benthic organisms, animal and plant (Becker 1983). Major foods of young include cladocerans, copepods, and algae; adults eats various insects, crustaceans, mollusks, other invertebrates, algae, and plant material. Feeds primarily in shallow shoreline areas in reservoirs. (Sublette et al. 1990).

Life History and Behavior
Life Cycle
Reproduction
Spawns in spring and summer, the date depending on locality. Eggs hatch in 1-2 weeks. Sexually mature in one to several years, at younger age in south than in north (Becker 1983).
