Economics of fish hatcheries and grow out
- 1. ECONOMICS OF FISH HATCHERIES AND GROW-OUT
- 2. SYNOPSIS • Introduction • Important factors • Selection of site for Hatchery • Purpose • Outline • Grow out of hatchery • Conclusion
- 3. INTRODUCTION A fish hatchery is a "place for artificial breeding, hatching and rearing through the early life stages of animals,fin fish and shell fish in particular“. Hatcheries produce larval and juvenile fish primarily to support the aquaculture industry where they are transferred to on-growing systems i.e. fish farms to reach harvest size. Some species that are commonly raised in hatcheries include shrimp, Indian prawns, salmon, tilapia and IMC. The U.S. Fish and Wildlife Service have established a National Fish Hatchery System to support the conservation of native fish species.
- 4. Important factors • Following factors should considered before the construction of a fish hatchery. 1. Construction and lay out of fish hatchery and tanks. 2. The number of fish tanks and selection of the type of fish breeding. 3. Selection of suitable fishes for breeding. 4. Conditioning procedures of tank.

- 6. Selection of site for Hatchery • Topography • Soil Quality • Water supply & Quality • Electricity • Marketing • Transportation of fish Seeds. Fig.Transportation of fish seeds through 02.
- 7. Purpose • 1. Out of season production Supply can be further guaranteed by sourcing from hatcheries in the opposite hemisphere i.e. with opposite seasons. • 2. Genetic improvement Genetic improvement can be mediated by selective breeding, via hybridization, or other genetic manipulation techniques.

- 13. GROW OUT OF HATCHERY
- 14. GROW OUT OF HATCHERY
- 15. GROW OUT OF HATCHERY
- 16. Conclusion Hatcheries, nurseries, and grow-out of fish such as groupers provide potential sources for the diversification of rural livelihoods and poverty alleviation. These also provide a solution to the degradation of the environment attributed to destructive practices in the live food fish trade.
