Artificial reproduction of Siganus sutor using LHRHa2 and HCG in Hormozgan Province, south Iran

Abstract

Feasibility of reproduction of rabbitfish, Siganus sutor, using LHRHa2 and HCG hormones were carried out during the years 2003 and 2004. Thirteen fishes were injected in April and May 2004 with LHRHa2 and HCG hormones used for males and females respectively. Injection dosage was 200 mu g/kg of fish body weight amounting to 500 IU fish/day. Fish larvae were fed with rotifers which were themselves fed with cultured algae. Two injected female fish and four males responded to injection and spawned in April 2004. The total number of obtained eggs was 1,404,000. Fertilization and hatching rate were %100 and %98.5 respectively. Results revealed that reproduction of Siganus sutor is possible in Hormozgan Province, south Iran.
