Yellow Perch - General Description

General Description

Yellow perch is often recognized by its dark vertical stripes and gold or yellow body color. Perca is derived from early Greek for "perch" and flavescens is Latin for "becoming gold" or "yellow colored". Adult sizes typically range from 3.9–11.4 in (10–30 cm); though have been known to grow larger. The yellow perch has a laterally compressed body with an oval,oblong shape. The anal fins are a green or yellow-orange, the dorsal fin is an olive color, and the belly is cream-colored. The vertical bands fade as they near the belly. Spawning intensifies the bands in males, and they can be nonexistent in juveniles. The spiny anterior dorsal fin has 13 to 15 spines. The soft rear fins also have one to two spines, but which are mostly made up of rays that range from 12 to 15 in number. The pelvic fins are close together, and the homocercal caudal fin is forked. The operculum tip has one spine, and the anal fin has two spines. There are seven to eight branchiostegal rays. Yellow perch has many fine and sharp teeth. Yellow perch are rough to the touch because of their ctenoid scales. Common names for the perch are yellow perch, American perch, and lake perch. Yellow perch are one of the smaller-sized members of the perch family (Percidae). Due to its ability to crossbreed and the similar morphology, the yellow perch is sometimes classified as a subspecies of the European perch. For over 100 years, Canada and the United States have been commercially harvesting yellow perch in the Great Lakes with trapnets, gillnets, and poundnets. In Canada, the estimated catch in 2002 was 3,622 tons with a value of $16.7 million, second only to pickerel at $28.2 million. The greatest demand in the United States is in the north central region, where nearly 70% of all yellow perch sales in the U.S. occur within 80 km (49.7 mi) of the Great Lakes. Yellow perch is one of the easiest fish to catch, and can be taken in all seasons, and tastes great. Therefore, it is a desirable sport fish in some locations of the US and Canada. It even makes up around 85% of the sport fish caught in Lake Michigan. A small aquaculture industry in the U.S. Midwest contributes approximately 90,800 kg (200180 lbs) of yellow perch annually, but the aquaculture is not expanding rapidly.
