Description

The freshwater drum (Aplodinotus grunniens) is the only freshwater drum of the family Sciaenidae, occurring in North and Central America. The species has a deep, silvery-grey body with an arched back and can reach about 95 cm. It inhabits the bottom of medium to large rivers and lakes. With powerful pharyngeal teeth it crushes mollusks and snails; it also eats aquatic insects, amphipods and fishes. The species owes its name to the deep, drumming sound that males make with special muscles against the swim bladder, especially in the spawning season. It is a valued sport fish and is eaten locally.
