Catfish: Feeds & Feeding

It is essential to provide a complete diet because catfish can synthesize only a small portion of the required nutrients and the quantity of nutrients from natural food organisms in the pond is relatively small.
Catfish feeds contain grain or grain by-products that are rich in starch. Starch helps bind feed ingredients together and increases expansion of extruded feeds so that the feed pellets are water stable and float in the water.
Catfish feed are generally supplemented with a vitamin premix to meet dietary requirements and to compensate for losses due to feed manufacture and storage.
Catfish feeds are also supplemented with phosphorus and a trace mineral premix.
In general, fish should be fed once a day as much feed as they will consume without adversely affecting water quality.
Most catfish producers feed once a day, 7 days a week during the warmer months. Although feeding twice a day may slightly improve growth of fingerlings, the logistics of multiple feedings on large catfish farms make it impractical.
Feeds should be scattered over as wide an area as possible to provide equal feeding opportunities for as many fish as possible.
Overfeeding should be avoided since wasted feed increases production costs.
