Out-of season induced spawning of the Cyprinus carpio in Basra-Iraq

The out-of season induced spawning of the Cyprinus carpio was done during period October 2009 to February 2010 (Autumn and Winter), in hatchery Marin Science Center. brooders average weight 1.700-4.000 kg for females 1.500-1.800 males. were acclimated on 22 °C, a 10 days. photoperiod 12-14 hour/day. results showed that this regime only one female 3males had positive reaction pituitary gland hormone injection. While 4 Ovaprim second regime, which 25 days, with same temperature photoperiod. It seen thermal acclimation long better maturation spawning, use give more response than PG extract. indoor rearing larvae gives 0.5 g after 6 weeks. These means we can produce fry common carp before month prior usual season, will prolong production Basra Province.
