Catfish

Distinct pairing. Mouth brooding may be employed as a parenting strategy (Ref. 205).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Inhabits coastal waters, as well as estuaries and tidal rivers. Feeds mainly on invertebrates and small fishes. The sharp dorsal and pectoral fin spines can inflict painful wounds. Sold mostly fresh and dried-salted in markets.
