freshwater drum

The freshwater drum (Aplodinotus grunniens) is a species of fish belonging to the Sciaenidae family, which are commonly known as drums or croakers. These fish are carnivorous and typically inhabit the bottom of freshwater environments, though some members of the broader drum family are marine.12

Freshwater drums are characterized by two dorsal fins and are usually silvery in color. They are known for their ability to produce sounds by vibrating their air bladder, which acts as a resonating chamber. This species can be found in the Great Lakes and Mississippi River valley and can grow to weigh 50 pounds (23 kilograms) or more. They are also sometimes referred to as sheepshead or white perch.12
