What is a perch?Perch are members of the Class
Osteichthyes, or bony fishes. Food enters the fish’s mouth and passes through the stomach and into the intestine. Digestion is aided by bile produced by the liver, which is attached to the intestine. Solid waste passes out through the anus.

MovementMovement is achieved by the action of muscles attached to the bony skeleton of the fish and is guided by the action of several types of fins. The fish has an air bladder in its body to help it stay afloat.
