Rounded Global Status Rank: G5 - Secure
Habitat Type: Freshwater
Comments: This catfish is characteristic of deep areas of main channels and backwaters of medium to large rivers; it occurs on the bottom during daylight hours in deep areas and moves into swifter water at night to feed. In reservoirs, it occurs in deep water during the day, in the littoral zone at night. It also occurs in some fish-farm ponds. It tolerates salinities up to 22 ppt (Sublette et al. 1990). Eggs are deposited in nests under logs, brush, or riverbank (Manooch 1984); nest prepared by male often in pools or backwaters (Sublette et al. 1990).
Population
Total adult population size is unknown but presumably exceeds 10,000. This species is fairly common (Page and Burr 2011).
In Missouri, stocking of this species in small impoundments has not resulted in the establishment of self-sustaining populations (Pflieger 1997).
Trend over the past 10 years or three generations is uncertain but probably relatively stable or slowly declining.

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.
