Perch fish are a popular gamefish found in freshwater habitats worldwide. There are many types of fish with “perch” in their name, but not all of them are true members of the perch family. True perch are fast swimmers with a long and round body shape, and they have two dorsal fins that can either grow separately or joined.
Perch fish are mainly carnivorous, feeding on insects, crayfish, and other fish, but they are considered omnivores because adult perch will also eat freshwater vegetation and algae.

Within the family Percidae, there are three main species of perch fish: the European perch fish, the yellow perch fish, and the Balkhas perch fish. In this article, we will discover all types of perch fish, their characteristics, and where they can be found.
8 Types Of Perch Fish
European perch fish (Perca fluviatilis)
The European perch fish (Perca fluviatilis) is a predatory freshwater fish that lives in slow-flowing rivers, deep lakes, and ponds. They are greenish-yellow in color with five to nine dark vertical bars on their flanks and red pelvic, anal, and caudal fins. The first dorsal fin is gray with a black spot at the tip, while the second dorsal fin is greenish-yellow, and the pectoral fins are yellow.
The European perch is most abundant in relatively shallow lakes and lakes with deep light penetration, and less abundant in deep lakes and those with low light penetration. Juvenile perch feed on zooplankton, bottom invertebrate fauna, and other perch fry, while adults feed on both invertebrates and fish, mainly sticklebacks, perch, roach, and minnows.
The European perch is fished for food and as a gamefish, and its flesh is described as good eating, with a white, firm, flaky texture and well-flavored.
Yellow perch fish (Perca flavescens)
The yellow perch fish (Perca flavescens) is a freshwater perciform fish native to much of North America. It is also known as perch, striped perch, American perch, American river perch, or preacher.
The yellow perch was described in 1814 by Samuel Latham Mitchill from New York, and it is closely related and morphologically similar to the European perch (Perca fluviatilis).
The yellow perch is a schooling fish that inhabits lakes, ponds, pools of creeks, and rivers, and it is most commonly found in clear water near vegetation. Adult yellow perch are usually golden yellow, while young are usually more whitish, and they have six to eight dark vertical bars on the sides of their body.
The yellow perch has a spiny dorsal fin with 12-14 spines and a second dorsal fin with 12-13 soft rays plus 2-3 spines, and there is usually a blackish blotch on the membrane between the last 3 or 4 dorsal spines.

Yellow perch are relatively poor swimmers, and they do not accelerate quickly, but they are schooling fish, which may help overcome this poor swimming ability by providing protection for younger fish and easier prey capture for older fish. The yellow perch is a popular food and sport-fish, with good flavor, and easy to catch, but it is prone to overfishing in some areas.
Balkhas perch fish (Perca schrenkii)
The Balkhas perch fish (Perca schrenkii) is a species of perch endemic to the Lake Balkhash and Lake Alakol watershed system, which lies mainly in Kazakhstan. Here are some characteristics of the Balkhas perch fish:
– The Balkhas perch fish is similar to the European perch and the yellow perch in its general profile and modest size, reaching a maximum total length of 50 cm and weight of 1.5 kg.
– It has a slimmer build and is lighter in color than the other two species of perch.
– The Balkhas perch fish has spines on the tips of the opercula and in the dorsal, pelvic, and anal fins, as well as sharing a similar dentition with the other two species of perch.
– It has ctenoid scales that lend a rough texture to the fish when handled.
– The Balkhas perch fish is a predatory fish that feeds on small fish, crustaceans, and insects.
– The species has suffered a population decline which is blamed on introduced bream and predatory fish such as the Volga pikeperch.
Despite its adaptable external morphology and life strategy, the future of the Balkhas perch fish is uncertain.
White perch fish (Morone americana)
The white perch fish (Morone americana) is a freshwater fish that belongs to the temperate bass family, Moronidae, and is notable as a food and game fish in eastern North America. Here are some characteristics of the white perch fish:
– The white perch fish is not a true perch but is a member of the temperate bass family, Moronidae.
– The white perch fish is a small silvery, greenish-gray fish with a dark, highly domed back, and a whitish belly.
– The white perch fish has a spiny dorsal fin with 12-13 spines and a second dorsal fin with 1 spine and 12-13 soft rays.
– The white perch fish is a predacious and opportunistic feeder, with young feeding primarily on zooplankton and adults feeding on aquatic insect larvae, minnows, and fish eggs.
– White perch are primarily piscivorous, feeding on other fish such as those in the families Cyprinidae and Osmeridae.
– The white perch fish is normally found along the Atlantic coast of North America from New Jersey to South Carolina, but it has been introduced into Lake Erie and Lake Ontario, and many smaller lakes.
– White perch usually live in estuaries (such as the Chesapeake Bay), where the water is slightly salty, but they can also live in freshwater, as in Lake Erie and Lake Ontario.
– White perch are important to humans as a source of food and recreational fishing, with many millions caught each year, especially along the Atlantic coast from Massachusetts to North Carolina.
The white perch fish is not a true perch, but it is a popular gamefish and food source in eastern North America.
Silver perch fish (Bairdiella chrysoura)
The silver perch fish (Bairdiella chrysoura) is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. Here are some characteristics of the silver perch fish:

– The silver perch fish is a member of the drum and croaker family, and it has an oblong and laterally compressed body.
– The silver perch fish is found inshore in seagrass beds, tidal creeks and rivers, and marshes along the eastern coast of North America from New York to Mexico.
– The silver perch fish spawns in shallow, saline portions of bays and other inshore areas, peaking between May and September.
– Silver perch are rarely targeted as game fish due to their small size, though they are considered good eating and are most commonly caught as bycatch when fishing inshore or nearshore for species such as black drum and sheepshead.
The silver perch fish is a small, silvery fish that is commonly found in shallow waters along the eastern coast of North America.
