The perch falls under the phylum Chordata, class Actinopterygii, subclass Neopterygii, and order of Perciformes. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. Even though Perch can be found all over the world, they are most likely found in the Great Lakes, Particularly in Lake Erie.
Perch are most commonly found in small ponds, lakes, streams, or rivers. These fish feed on smaller fish, shellfish, or insect larvae, but can be caught with nearly any bait. They commonly spawn during the spring, when the females lay strings of eggs in covered areas such as near branches or underwater plants.
The predators of the Perch are mostly larger fish such as Largemouth bass, Smallmouth bass, Channel Catfish, and Black Crappie.
