Artificial reproduction of royal carp (Cyprinus carpio)

The aim of this study was to establish an experimental protocol for the artificial reproduction royal carp ‘Cyprinus carpio’ with hormonal induction spawning. For purpose, we conducted at aquaculture farm in Khemis Meliana (Ain Defla, Algeria). included six broodstock, 4 females and 2 males. Hormone injection performed dorsal muscle under fin. done successively by GnRH a dose 3 mg/kg males hCG 500 IU per kg weight. Fertilisation artificially dry method. After incubation eggs, binocular magnifying glass used check condition eggs development embryos over time. results obtained show that species possible, success ovulation fertilisation, hatching growth larvae. Stripping after 24 h stimulation temperature 21°C. Disaggregation efficiently whole milk. total number 552,000 weight 1104 g. average latency time 22 hours. rate days on spawning grounds 21±1°C 441,600 larvae (80%). Larvae food follow-up started from 3rd day post-hatching combination natural (rotifers) food. At end experiment, can conclude it is possible improve through proper use techniques improving feeding abiotic factors are dominant fish farming.
