Feeding strategy for catfish production : Producers should consider that the catfish require different feeds at each stage of growth. It is best to feed a 40% protein feed in a crumble form to the smallest fingerlings. Catfish that are about 3 inches long can utilize a 3/17 inch floating pellet of 36-37% protein content. Once catfish fingerlings are stocked into food fish production tanks, the options for feed quality are more numerous. One of the recent options is whether to feed a lower protein feed of about 29% protein or the more customary 33% protein feed. Research with tank raised catfish reports that until the protein content is reduced to 25% the catfish production is comparable to when 33% protein feed is used.
Feeding times effect the weight gain of catfish but weight gain is usually not as important as labor and logistics on large catfish farms. For example, it has been reported that feed offered at two times each day will produce more weight gain than a single daily feeding. However, it has also been reported that offering feed when tank water dissolved oxygen concentrations are low is not advisable. So, feeding twice a day or morning and evening is difficult most of the year when dissolved oxygen levels are low in the morning. Aeration can be applied to boost the dissolved oxygen but at the added expense of the cost of electricity to run the aerator. For most producers, catfish in the fingerling stages are fed twice daily but catfish in food fish stages are only fed once daily.
Successful catfish farming generally requires constructing facilities, controlling water quality, rearing, stocking and feeding fish and harvesting and marketing the fish crop. A fish farmer can grow catfish in Cement Tank, ponds, cages or raceways. A well-balanced catfish diet consists of Sinking pellets or flake foods.
