Breeding techniques of common carp (Cyprinus carpio) using different approaches.

33 brood fish of Common Carp (Cyprinus carpio ) obtained from Panyam Fish Farm, was used to evaluate the percentage hatchability of Carp through un induced natural spawning in Outdoor Hapa Net System, induced natural spawning in Outdoor Hapa Net System, and induced breeding by stripping in Indoor Concrete Ponds. Spawning and fertilisation was natural for treatment 1. Ovaprim hormone was used to induce brood fish in treatment 2 and 3, but unlike treatment 3, treatment 2 was not stripped manually, as the induced female brood fish shed her eggs naturally. At the end of the experiment, the mean number of eggs in one gram was found to be (733.33 ± 3.53a) in treatment 3, as compared to that of treatment 2 (702.00 ± 3.21b) and treatment 1 (709.33 ± 4.91b), with a significant difference at (P<0.05). There was no significant difference (P<0.05) in fecundity (×103 )from the three treatments. Percentage fertilization was highest in treatment 2 (94.44 ± 0.40a). Percentage Hatchability was highest in treatment 3 (94.10 ± 0.85a). Number of Post Fry in one liter of water at day seven after hatching was found to be highest in treatment 3 (1896.30 ± 53.40a). In conclusion, the best method of Carp fish propagation for aquaculture is the synchronized propagation through stripping in indoor concrete ponds, which had 94% hatching rate.
