Description

The blackspotted croaker is a large croaker (Sciaenidae) from turbid coastal and estuarine water of the Indo-West Pacific. The species can grow to about 1.5 metres and has an elongate body that in juveniles is dotted with black spots, and a large swim bladder with which it makes a loud drumming sound. As a predator it searches over sand and mud for fish, shrimp and crabs. It is a highly valued food fish, partly for its swim bladder. The fish is harmless to humans.
