Inhabits deep water of impoundments and main channels and backwaters of medium to large rivers, over mud, sand and gravel (Ref. 5723, 86798). Stays on the bottom during the day in deep areas and moves into swifter water at night to feed (Ref. 117513). Feeds on small aquatic invertebrates, clams and fishes (Ref. 93252). Prefers clear, strongly flowing water. Deposits eggs in nests under under logs, brush, or riverbank (Ref. 117513). Males build nest often in pools or backwaters (Ref. 117513). Marketed fresh and frozen. Eaten steamed, fried, broiled, microwaved and baked (Ref. 9988).
