The reproduction biology of Abudefduf sexfasciatus in the Persian Gulf (Larak Island)
The reproduction biology of A. sexfasciatus, one of the main and important ornamental fishes in the Persian Gulf were studied during 1997-98. For sampling, Larak island sited on south-eastern of Bandar-Abbas was chosen. The main fishing gear was hook for collecting samples. During this investigation, weight, length (FL & T.L), GSI, HSI, Kf, sex ratio, LM50 and sexual overlap zone were measured or calculated. Also, the histological studies were done on gonads. The results showed that this species is a protogenous hermaphrodite. A. sexfasciatus has an allometric growth and the results of GSI, HSI and Kf indicated that the spawning season occured in spring as a total spawner species. The sex ratio was found M:F=1.00:1.24 without any significant difference. The overlap zone was recongnized 30mm (with a range of 125-155mm). The LM50 was calculated 130-140mm for females and 160-170mm for males. The size at first maturity for females and males were determined 105 and 120mm, respectively.
