The Atlantic croaker is the smallest member of the Sciaenidae family of drums. The species gets its name from the croaking sound it makes from the voluntary contraction of muscles attached to the air bladder, which acts like a resonance chamber. It’s unclear whether the croaking is a form of communication within a school of fish, a means of depth sounding or a mating expression, but croakers tend to make the sound most often during breeding season. Though some 3- to 5-pound croakers are available, market size is 3/4 to 1 1/2 pounds. Atlantic croaker is found in the Atlantic and Gulf, from Cape Cod to Texas. The Chesapeake Bay region and Mississippi Delta are particularly productive areas. Croakers are caught with gillnets, pound nets and fish traps. In parts of the Gulf, Atlantic croaker is a bycatch of shrimp trawlers.
