Unit 3 - Nursery, Rearing and grow-out ponds
3.1. Preparation and Management of Nursery, Rearing and grow-out ponds The following definition will help to understand the concepts discussed in this units.
- Nursery ponds: Ponds where spawn are reared to fry stage. In carps it takes about 15-20 days to grow spawn to fry size
- Rearing ponds: These are ponds where fry are grown to fingerling size. In carps it takes about 2-3 months to rear fry to fingerlings size.
- Grow-out ponds: In these ponds fingerlings are stocked and grown to harvestable size. Carps grow from fingerlings to marketable size in about 10-12 months.
- Aquaculture as defined earlier is the Farming of aquatic organisms
- Farming implies intervention in the rearing processes to enhance production.
- Intervention strategies to enhance pond production of fish can be broadly classified as pre-stocking management stocking and post-stocking management
