About Bowfin
Bowfin go by many names, including freshwater dogfish, beaverfish, grinnel, swamp trout, mudpike, and choupique, among others. They are sometimes referred to as primitive because they share certain morphological characteristics with their early ancestors. Bowfin are able to breathe both water and air. They use their gas bladders not only to aid in buoyancy, but also to breathe air from the surface.
Appearance and Size
Bowfin have a distinct appearance. They have long, cylindrical bodies and are generally mottled olive to brown with lighter bellies. Net-like patterns on their sides help them camouflage. Bowfin have very long dorsal fins and rounded tail fins, both of which feature stripes. They also have barbel-like tendrils at each nostril. Adult males can reach about 24 inches long, while females can grow as long as 30 inches. They typically reach weights of around 8.5 pounds.

Female bowfin typically grow larger than male bowfin.
Distribution and Habitat
Bowfin are widespread throughout North America, especially in the eastern United States. They can be found in southern Quebec and Ontario through the St. Lawrence River and Great Lakes regions. These fish can be found in the Mississippi River Basin from Minnesota to Louisiana, as well as across the Gulf Coast from Texas to Florida. There is also a population in the Appalachian Mountains.
Bowfin prefer deep, densely vegetated, slow-moving backwaters, lakes, and streams. They favor clear water, but they are also tolerant of silt and mud. These fish can often be found taking shelter under roots, logs, or fishing piers.
Diet
The diet of bowfin changes as they age. Young bowfin usually eat insects and other microscopic organisms. However, when they reach 4 inches or longer, they start eating small fish. Mature bowfin consume fish, frogs, aquatic insects, and fish eggs. They are excellent hunters and are opportunistic feeders. Sometimes, anglers use live bait such as minnows, salamanders, and frogs to capture bowfin.
Predators
The main predator of bowfin is humans; however, they are also hunted by larger fish, mammals, and birds. One of the most common bowfin predators is the American alligator when they live in the same body of water. Although bowfin meat is edible, many do not consider it suitable as table fare. Fishermen who do consume bowfin recommend keeping them on ice or alive until just before cooking.
