Nutritional advances have greatly reduced the cost and improved the effiiency of channel catfish diets.
Importance of practical nutrition studies
Most commercial catfish feeds have been formulated based on nutrient requirements determined with young catfish raised under controlled environments in the laboratory, which is much different from the environment in which catfish are raised commercially.
Reducing diet cost
Early catfish feeds used for raising food fish often contained 35 percent or more protein and 12 percent to15 percent marine fish meal. Today 28 percent to 32 percent protein diets are commonplace, and they rarely contain more than 4 percent marine fishmeal and some do not contain any.
Feeding practices
In addition to diet development, considerable research effort has been expended on evaluating feeding practices for catfish. Even though catfish have been cultured for years and a considerable amount of information on nutrition and feeding is known, feeding catfish is still as much an art as it is a science.

What is catfish feed?
Commercial catfish feeds are a mixture of feedstuffs and vitamin and mineral supplements that provide adequate amounts of essential nutrients and digestible energy. To be suitable, dietary ingredients must be highly digestible, easily handled in the manufacturing process, able to withstand the rigors of the manufacturing process, available on a consistent basis, economical, and contain sufficient nutrients. Although all feedstuffs contain energy, protein, and other nutrients, they are usually classified as either protein or energy feedstuffs. In animal feeds, those containing 20 percent protein or more are generally referred as protein feedstuffs, and those containing less than 20 percent protein are energy feedstuffs. Protein feedstuffs are further divided by the source, either animal or plant. There are many feedstuffs that may be nutritionally suitable for use in catfish feeds, but relatively few are readily available on a timely basis and at reasonable cost. Although we will consider all types of feedstuffs, we will focus mostly on protein feedstuffs, as protein is the most costly fraction of catfish feeds.
