Feeds on invertebrates, benthic species, mollusks and small crustaceans (Ref. 89972). Can tolerate oxygen poor water by inhaling air into a lung-like air bladder (Ref. 9710). Migrates to mass spawn at seaward mouths of channels on lunar cycle (Ref. 9710). Sold fresh in markets but seldom used for human consumption.
