Perch are carnivorous fish found in ponds, lakes, streams, and rivers. They feed on smaller fish, shellfish, and insect larvae. Humans eat perch. Perch can be found all over the world, esp. in the Great Lakes. Their stripes are an adaptation for camouflage and help the perch hide in aquatic vegetation. Perch breed in the late spring, laying their eggs on soft vegetation. Perch have two dorsal fins, one spiny and the other soft-rayed.
