Goldtail croaker
(Bairdiella chrysoura)

Bairdiella chrysoura, the American silver perch, silver croaker or goldtail croaker, is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers.

This species is widespread along the eastern cost of North America and is commonly caught by inshore anglers in search of larger species.

This fish is common up to 20 cm (7.9 in), but can be found uncommonly to 30 cm (12 in).

Bairdiella chrysoura 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 family Sciaenidae). 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 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.

Silver perch are similar in appearance to the sand seatrout or silver seatrout, two closely related species of weakfish. Seatrout usually have 1 or 2 prominent canine teeth at the tip of upper jaw and do not have chin pores.
