Abstract :
The barbus fish is a genus of Cyprinidae in wet lands and rivers of Khuzestan Province. Barbus sharpeyi is a popular and good species for aquaculture. This study was done with the purpose of determination of bio technique of artificial breeding of Barbus sharpeyi in Khuzestan Province. In this study 400 female and 200 male broad stocks were injected and 346 of females and 144 of males were responded for breeding. The ratio of males to females was 1: 2. Fertilization percentage and hatch percentage were 65 + 2.76 and 62.2 + 2.25 and 65% of males & 70% of females were responded. The mean of fecundity of the whole fertilized egg were respectively 19856.56 + 988. 62 and 4823000 +1278.39. The number of cultured larvae and the survived fingerlings were 1600000 and 500000. The survival rates of the larvae with 1 and 7 gr weights were respectively 16% and 40%. At the end of the experiment, 3500 kg fingerlings were cultured. The results showed that the artificial breeding of Barbus sharpeyi can be done in Kkuzestan climate and this fish has a good resistance against the temperature and oxygen content changes during the breeding so artificial breeding of this species for aquaculture in Khuzestan province ponds is beneficial.
