What prota
Fish, diverse group of animals that live and breathe in water. All fishes are vertebrates (animals with backbones) with gills for breathing. Most fish have fins for swimming, scales for protection, and a streamlined body for moving easily through the water.

CAT FISH
CAT FISH
Catfish, common name for about 2200 species of fishes, of which some 1200 are South American. Two families are primarily marine. All other families inhabit fresh water. Catfishes are mostly nocturnal scavengers, living near the bottom in shallow waters.
The name catfish is derived from the feelers, or barbels, that extend from each side of the upper jaw of the fish and, in some species, from the lower jaw also, suggesting the whiskers of a cat. The dorsal and pectoral fins are often edged with sharp spines, in some cases poisonous, which are used in defense and can inflict severe wounds. Members of several catfish families in South America are covered with bony plates. A European species, the sheatfish, or wels, is the largest catfish, reportedly reaching a weight of 290 kg (650 lb) and a length of almost 4 m (almost 13 ft).
The blind catfish, found in caverns in eastern Pennsylvania, has atrophied eyes, and the electric catfish of the Nile River and tropical central Africa is capable of giving an electric shock. Another odd catfish, the so-called walking catfish, originally occurred in eastern India and Southeast Asia. In 1968, it was discovered near Boca Raton, Florida, following its import by tropical-fish dealers. Its maximum length is 56 cm (22 in). In “walking” to areas of deeper water in dry spells, this catfish moves across land (between bodies of water) by a slithering motion combined with a thrashing of its tail. In addition, a stout spine in each pectoral fin digs into the ground to help balance and propel the fish. It is able to breathe air by means of a modified gill arch that forms an air chamber.
Some species of catfish are believed to be among the largest freshwater fish in the world. A specimen of giant catfish, (Pangasianodon gigas) netted in 2005 in the Mekong River in northern Thailand, reportedly weighed 293 kg (646 lb) and measured 2.7 m (9 ft) in length.
Of the numerous species of North American catfishes, the bullhead is commonly fished for eating. Of greatest commercial importance are fishes in the Mississippi River valley and the Gulf states, some of which weigh as much as 70 kg (as much as 150 lb). The blue catfish, or chucklehead, and the channel catfish, the flesh of which is esteemed as equal to that of black bass, form the major part of the harvest.
Catfishes currently account for about one-half of the aquaculture production in the United States. Mississippi, Alabama, Arkansas, California, and Louisiana all have extensive catfish farms; there are a total of about 60,700 hectares (about 150,000 acres) of catfish farms in these and other states. The United States production of farm-raised catfishes increased from less than 90 million kg (less than 200 million lb) in 1985 to more than 200 million kg (more than 450 million lb) in 1992, and commercial sales of farmed catfishes were estimated at about 200 million kg (about 450 million lb) in 1993. New technologies such as genetic improvement, recirculating systems, and control of diseases may continue to promote the growth of this industry.


SCIENTIFIC CLASSIFICATION:
Catfishes make up the order Siluriformes. The two marine families are Ariidae and Plotosidae. The sheatfish is classified as Silurus glanis, the blind catfish as Gronias nigrilabris, the electric catfish as Malapterurus electricus, and the walking catfish as Clarias batrachus. Bullhead belong to the family Ictaluridae. The blue catfish is classified as Ictalurus furcatus, and the channel catfish as Ictalurus punctatus.





Channel Catfish
The channel catfish is a commercially important food fish. Its tasty flesh has been compared to black bass. Originally found in freshwater streams and lakes in central and eastern parts of the United States and southern Canada, channel catfish have been introduced widely throughout the United States. Catfish farming, or raising catfish commercially in large ponds, is expanding rapidly in the southeastern United States.


Brown Bullhead
Valued for food and sport, the brown bullhead, a North American species of catfish, lives in many freshwater streams in the eastern United States. Usually measuring less than 46 cm (18 in) long, the brown bullhead exhibits the typical whiskerlike feelers that give the catfish its name. The brown bullhead is considered the most commercially important of all catfish.



Catfish Walking on Land
Catfish (named for whiskerlike feelers on their jaws) are a diverse collection of tenacious fish that have adapted to life in a variety of environments. There are more than 2000 different species. One type of catfish, Clarias batrachus, commonly known as the walking catfish, is native to shallow ponds in eastern India and Southeast Asia. When droughts cause shallow ponds to dry up, the walking catfish is capable of traveling across land to move to deeper ponds. It uses its pectoral fins and tail to slither across the ground, or “walk,” in search of a suitable new pond, surviving on oxygen stored in an air chamber in its gill arch.
