== Description ==
The American silver perch has a moderately large, obliquely rising terminal mouth. The lower jaw projects further than the upper jaw. The chin does not bear a barbel but has three pairs of mental pores (the arrangement of the barbels and under-chin pores provides a means to distinguish between different members of the Sciaenidae family). The preopercle, the bony plate just in front of the operculum, bears a few spines set at an angle. The dorsal fin has ten to eleven spines and nineteen to twenty-three soft rays. The anal fin has two spines, the second of which is sharp and more than two thirds the length of the first soft ray, and eight to ten soft rays.
This fish has a two-chambered swim bladder which is connected to the inner ear. It has good hearing, on a par with the goldfish (''Carassius auratus'') which is renowned for its auditory ability. Its general color is silvery, greenish, or bluish on the dorsal surface and silvery or yellowish on the underside. The fins are yellowish or greyish.〔(【引用サイトリンク】title= ''Bairdiella chrysoura'' (Lacepède, 1802): Silver perch )〕
