The corvina, also known as the corvina drum (Cilus gilberti), is a saltwater fish of the Sciaenidae family (commonly called croakers or drums). It inhabits mostly tropical to temperate coastal waters of the southeastern Pacific along Central and South America. The corvina is highly prized in South America as a food fish.
The corvina is similar in appearance to its relatives the weakfish and spotted seatrout. Its body is blue-grey on top, silvery overall with small scales, and is elongated and somewhat compressed in shape. It has a large mouth and a dorsal fin that is deeply notched between spiny and soft parts. It reaches 75 cm (30 in) in length.
