The blue catfish is the largest species of North American catfish with a typical length of about 2 feet (61 cm) and weight of about 30 lb (14 kg). The fish can live to 20 years. The native distribution of blue catfish is primarily in the Mississippi River and Louisiana drainage systems, including the Missouri, Ohio, Tennessee, and Arkansas Rivers, the Des Moines River in south-central Iowa, the Rio Grande, and south along the Gulf Coast to Belize and Guatemala. These large catfish have also been introduced in a number of reservoirs and rivers, notably the Santee Cooper lakes of Lake Marion and Lake Moultrie in South Carolina, the James River in Virginia, Powerton Lake in Pekin, Illinois, and Lake Springfield in Springfield, Illinois. This fish is also found in some lakes in Florida. The fish is considered an invasive pest in some areas, particularly the Chesapeake Bay. Blue catfish can tolerate brackish water, and thus can colonize along inland waterways of coastal regions.
The redtail catfish, Phractocephalus hemioliopterus, is a pimelodid (long-whiskered) catfish. In Venezuela, it is known as cajaro, in Guyana, it is known as a banana catfish, and in Brazil, it is known as pirarara, stemming from the Tupi language words pirá and arara. It is the only extant species of the genus Phractocephalus. This fish is common in the aquarium trade, although its massive adult size makes it unsuitable for all but the largest aquariums. They feed on fish, crustaceans and fallen fruits. They are not evaluated by IUCN.
