it is found from Nova Scotia and New Brunswick to Mobile Bay, Alabama, and in the Great Lakes, Hudson Bay, and Mississippi River basins (from Quebec to Saskatchewan, south to Louisiana, and west to Texas). However, there is evidence that the brown bullhead was historically absent from the Gulf Coast west of the Apalachicola River and east of the Mississippi River. The species is also abundant in many regions as a result of stocking for food or sport. These locations include Georgia, Alabama, Arizona, Arkansas, California, Colorado, Hawaii, Idaho, Kansas, Kentucky, Louisiana, Maine, Missouri, Nebraska, Nevada, New Hampshire, New Mexico, Ohio, Oklahoma, Oregon, Virginia, and Washington. Brown bullheads are a social non-migratory species that are known to form schools. Habitat The brown bullhead thrives in a variety of habitats, including lakes, ponds, and slow-moving streams with low oxygen or muddy conditions. In many areas of the United States, brown bullheads are opportunistic bottom feeders. The species has few natural predators and is not popular with fishermen, so it has thrived. Catfish are found in a variety of habitats, from lakes or murky ponds to drainage ditches. They are scarce during the day, but come out at night to feed, searching the bottom of a lake or river for food. They eat insects, leeches, snails, fish, clams, and many plants. They are also known to eat corn, which can be used as bait. Similarly to other catfish, they spawn only after the temperature of the water has reached in June and July. However, cooler temperatures are required before brown bullheads will spawn in the northern US. Brown bullheads can withstand a wide range of water temperatures and low oxygen levels. Brown bullheads can survive waters with heavy pollution and dissolved oxygen values as low as 0.2ppm. Because of bullheads' tolerance of low oxygen levels, they are less threatened by winterkill and are capable of surviving in relatively extreme environments. Fishing This catfish is easily caught with natural bait such as worms and chicken livers. They have a scrappy but not unusually strong fight. Anglers often catch them by fishing off the bottom. When caught in very clear water when the flesh is firm and reddish to pinkish, the hornpout is quite edible and delicious. Nevertheless, its genial cousins such as the channel catfish and the blue catfish are better known for their use as food. In most areas, they will not
