Fish Feeds and Feeding
Fish feed
- Fish Feeds:
- Natural fish food:
(a) Phytoplankton (e.g. algae, rotifers, etc)
(b) Earthworms
(c) Insects and larvae
(d) Paw-paw leaves
(e) Maggot
Artificial fish food should be mentioned too
Fish feeding material
- Explain the feeding regime, such as 4% – 5% body weight for the fingerlings, juveniles and sub-adults, 2.5 – 3.5% body weight for adults.
- Period of feeding:
- Three times daily for fingerlings
- Two times daily for adults.
- Methods of feeding:
- Broadcasting
Fish Pond Preparation And Management
Fish Pond Preparation
- Preparation of new ponds:
- Flush in water and drain out after 21 days
- Check leakages
- Lime (for earthen ponds)
- Flush in water
- Fertilize
- Stock fingerlings
Pond Management
- Pond management are practices carried out to ensure optimum fish production
- Monitoring water quality.
- Daily checks of leakages/seepage.
- Stocking:
- Rate of stocking/stocking density (2 to 4 fish persquare meter depending on the culturing system)
- Method of stocking: lower the fingerlings with the container inside water to allow the fish to adjust to the new environment and swim out on their own.
- Period of stocking: early in the morning or late in the evening.
- Transportation of fingerlings should be done by using oxygenated bags or clean big containers.
- Feeding should be done daily.
- Sorting should be done monthly.
