Abstract :

In this study, some parameters of reproductive biology of the Longnose trevally (Carangoides chrysophrys), gonadosomatic index, sex ratio, absolute fecundity and relative fecundity and gonadal development stages were investigated. Sampling in the waters of the Hormozgan Province from March 2013 to March 2014 with fishing vessels by trawl and gillnet was performed. In the study, a total of 376 specimens were investigated. Of this number 194 were male, 137 female and 45 immature. The femaleto-male sex ratio was 1.42. The maximum absolute fecundity for the period March 21st- April 20th was 479992 ovules and the maximum relative fecundity in the period October 23rd-November 21st was 354 ovules per gram. The minimum absolute fecundity computed was 98247 for the period June 22nd-July 22nd and the minimum relative fecundity was 125 ovules per gram for the period June 22nd- July 22nd. The mean Gonado-Somatic Index (GSI) computed for various months was 1.28 and the greatest gonadosomatic index was 2.86 for the period March 21st- April 20th and the minimum GSI was 0.43 for the period May 22nd-June 21st. The length at first maturity was 46 cm (LM 50).
