The yellowfin croaker is a member of the family Sciaenidae (drum and croaker), known for the drumlike noises it makes when it raps a muscle against its swim bladder. The resulting distinctive drumming sound is amplified by the swim bladder and can be heard at some distance.
The sciaenids are one of the most important food fish in the world because nearly all species are good to eat and are harvested commercially. Found along the Pacific coast, the yellowfin croaker is a popular catch for light-tackle surf anglers.
Identification
The body of the yellowfin croaker is elliptical-elongate; the back is somewhat arched and the head blunt. Its coloring is iridescent blue to gray, with brassy reflections on the back, diffusing to silvery white below. Dark wavy lines streak the sides. The fins are yellowish, except for the dark dorsal fins. It has a small barbel on the chin tip and two strong anal spines; the barbel and the heavy anal spines distinguish the yellowfin from other California croaker.  |   |
