Spawning induction of Capoeta capoeta gracilis using Ovaprim TM

Capoeta capoeta gracilis (Keyserling, 1891) as a commercial valuable species belongs to cyprinid fish is native to Iran. In this study, the possibility of inducing artificial reproduction of C. Capoeta gracilis was investigated using OvaprimTM hormone. For this purpose, four wild-caught females and one male were selected. Female fish were injected by OvaprimTM at doses of 0.1 and 0.4 mg/kg with 12 hours interval. At the time of the second injection, the male fish was injected at a dose of 0.2 mg/kg. Spawning occurred less than 48 h after the first injection. Maximum and minimum of working fecundity were 2473.17 and 23430.5 number. The male fish did not respond to hormone injection and all of the broodstock positively responded to the hormonal induction. These preliminary results revealed that OvaprimTM is a suitable synthetic hormone for reproductive induction in C. capoeta gracilis.
