描述Although catfish have been farmed for about 30 years and catfish farm­ ing is the most successful aquacultural enterprise in the United States, there are those who contend that catfish farming is still as much of an "art" as it is a science. This position is difficult to refute completely, particularly considering that some practices used in catfish farming ap­ pear to have little scientific basis. Skill coupled with a small dose of mysticism certainly playa role in the culture of catfish, and the catfish producer is faced with the unenviable task of rearing an animal in an environment that requires considerable management. Certain aspects may still be an "art" because research and technical information needed to support the industry have lagged behind industry growth; however, the basic principles underlying catfish farming are based on sound scientific evidence whose foundation was laid in the 1950s by work conducted at state and federal fish hatcheries in the southeastern and midwestern United States. Since that time, several university and government laboratories have expanded the scientific base for catfish farming. As a result, considerable information is available, but it is

Genetics the same spawn and reared in the same environment. In nature, genetic variation is important because it enables populations to adapt to changing environments and survive. Genetic variation is important in channel catfish farming because the heritable component of variation can be exploited through

Environmental Requirementsm, the general well-being of the fish is affected. Fish respond to suboptimal conditions (stressors) by modifying metabolism or behavior in an attempt to adapt to the new conditions. Initial reactions (stress responses) include release of hormones that prepare the animal for emergency action by mobi

Breedingding programs based on genetic theory. Commercial channel catfish culture lags far behind most other farm animal culture in using genetic improvement programs to increase productivity, despite indications from research (summarized by Dunham and Smitherman 1987) that considerable progress can be made

Water Quality Management in Pondsish culture. Dissolved oxygen concentrations are near saturation, and the water contains negligible concentrations of carbon dioxide, ammonia, nitrite, or other toxic substances. When fish are stocked and fed, the environment immediately begins to deteriorate and becomes less fit for the fish. The d

The nutritional requirements of cultured catfish are met by using a feed that is formulated to provide all required nutrients (a complete feed) in the proper proportions necessary for rapid weight gain, high feed efficiency, and desirable composition of gain.
