Channel Catfish: Life History and Biology

Thomas L. Wellborn


Opening Paragraph:
Channel cattish, Ictalurus punctatus (Rafinesque), is the most important species of aquatic animal commercially cultured in the United States. It belongs to the family Ictaluridae, order Siluriformes. Members of the order Siluriformes are found in fresh and salt water worldwide. There are at least 39 species of catfish in North America, but only six have been cultured or have potential for commercial production. They are the blue catfish, Ictalurus furcatus (LeSueur); the white catfish, Ictalurus catus (Linnaeus); the black bullhead, Ictalurus melas (Rafinesque); the brown bullhead, Ictalurus nebulosus (LeSueur); the yellow bullhead, Ictalurus natalis (LeSueur); and the flathead catfish, Pylodictis olivaris (Rafinesque).
