The blue catfish, or chucklehead, and also the network catfish, the flesh of which is esteemed as equal to that of black bass, create the huge part of the harvest.

Catfishes currently account for concerning half of the sustainable aquaculture production in the USA. Mississippi, Alabama, Arkansas, California, and also Louisiana all have comprehensive catfish farms; there are a total of concerning 60,700 hectares (concerning 150,000 acres) of catfish farms in these as well as other states. The United States production of farm-raised catfishes enhanced from less than 90 million kg (less than 200 million lb) in 1985 to greater than 200 million kg (greater than 450 million lb) in 1992, and also business sales of farmed catfishes were approximated at around 200 million kg (concerning 450 million pound) in 1993. New technologies such as genetic renovation, recirculating systems, and control of illness may continue to advertise the growth of this market.

Catfishes compose the order Siluriformes. The two marine family members are Ariidae and also Plotosidae. The sheatfish is categorized as Silurus glanis, the blind catfish as Gronias nigrilabris, the electric catfish as Malapterurus electricus, and the strolling catfish as Clarias batrachus. Bullhead belong to the family Ictaluridae. Heaven catfish is identified as Ictalurus furcatus, and the channel catfish as Ictalurus punctatus.

Channel Catfish
The channel catfish is a commercially vital food fish. Its delicious flesh has been compared to black bass. Originally located in freshwater streams as well as lakes in central and eastern parts of the USA and also southerly Canada, network catfish have been introduced widely throughout the USA. Catfish farming, or increasing catfish commercially in huge ponds, is broadening quickly in the southeastern United States.

Brown Bullhead
Valued for food and sporting activity, the brown bullhead, a North American varieties of catfish, stays in numerous freshwater streams in the eastern USA. Normally measuring less than 46 cm (18 in) long, the brown bullhead displays the typical whiskerlike feelers that offer the catfish its name.

One sort of catfish, Clarias batrachus, commonly referred to as the walking catfish, is belonging to shallow ponds in eastern India as well as Southeast Asia. When dry spells trigger shallow ponds to run out, the strolling catfish can taking a trip across land to relocate to much deeper ponds. It utilizes its pectoral fins and tail to wriggle throughout the ground, or “stroll,” looking for an ideal brand-new pond, surviving on oxygen kept in an air chamber in its gill arc.
