2000
I. Kamali
Golden snapper is a species of family LUTJANIDAE which is distributed in Hormozgan waters. Biological (especially reproductive) study of each species is necessary both for the cultivation and stock assessment of that species. 613 specimens were sampled monthly from May 1996 to July 1997 in Hormozgan waters, for determining some reproductive factors such as Lm50, spawning season, fecundity and ratio. Spawning season was determined based on GSI from April 10 July with a pick in August. Length of fish in which half of females were matured (Lm50) was obtained at length of 44cm. Fecundity range was calculated in each month. Maximum fecundity was 2539592 in July. This fish is a total spawner species. Sex ratio was 1.23 female to 1 male. Chi square test was applied to compare female and male frequency, and did not show a significant difference (p=0.012) yearly.
