Attention should be given to feeding; it only increases production, it also helps the farmer to assess the behavior and health status of the fishes.
Supplemental fish feeds are usually obtained from agricultural by-products. They include oil cakes, industrial residue (e.g. brewers waste), animal by-products (like blood meal) and wastes (like chicken droppings). It is necessary to feed fishes with a balanced diet which is a combination of essential nutrients in different proportions.
The following are important during fish feeding:
- Use locally available foodstuff to reduce cost.
- Prepare feeds in small quantities to avoid loss and reduction in quality.
- Package and store feed properly in jute bags with polythene lining, bins with lids to avoid infestation. They should be stored in cool, dry places to avoid reduction in quality.
- Feed fish twice at specific times, usually 10 am and 5pm.
- Avoid overfeeding to prevent water pollution as unconsumed feed decomposes to release harmful gasses that can stunt fish growth.
- Monitor growth performance by visual observation during feeding
