Would you be surprised to learn that although there are many types of fish with “perch” in their name, they aren’t all true members of the perch family? One example is the white perch fish. While its name is “white perch”, this fish is actually a member of the bass family and not a true perch at all.
Perch are a bony type of fish found in freshwater habitats. They’re a popular gamefish because they are not only easy to prepare and nutritious to eat, they are known to put up an exciting challenge for anglers when caught on a line.
Perch fish are of the genus, Perca, belonging to the family Percidae. Within this family are three main species of perch fish. Read on to discover the three types of perch fish below!
3 Types of Perch Fish
The three species of perch fish include the European perch fish, the yellow perch fish, and the Balkhas perch fish. True perch are fast swimmers with a long and round body shape. The three species are similar in appearance, with some variations. All three types are ray-finned with paired pectoral and pelvic fins. They have two dorsal fins that can either grow separately or joined.
Perch fish are found throughout the world. They are mainly carnivorous, feeding on insects, crayfish, and other fish. However, they are considered omnivores because adult perch will also eat freshwater vegetation and algae.
