-To explore the environment, life, and role of a perch.
-To analyze the anatomy of a perch.
Most Perch species are adaptable to any form of habitat. However, a Perch, is best suited in clear water with moderate vegetation and lots of sand, mud, or gravel bottoms.
After hatching from eggs, perch larvae later grow into juvenile perches. At this stage, the perches migrate to riverine waterholes, where they stay until they are adults. After this, the perches travel upstream where they mate and lay more eggs, thus restarting the cycle.
Predators of the Perch
Predators of the perch include larger fish, such as Largemouth Bass, Smallmouth Bass, Black Crappie, Channel Catfish, Chain Pickerel, Walleye, Bluegill and other sunfish. Birds, including herons, gulls, eagles, hawks, kingfishers, and mergansers eat them as well.
Young Perch eat mostly algae and plankton. As they get older, they will begin eating aquatic insects. Larger Perch eat small fish, insects, crayfish, snails, mussels, leeches, fish eggs, and worms.
Perches enter the evolutionary cladogram fairly early, missing several features of those of their ancestors.
Perches are found mostly in the waters of North America.
