The length-weight relationship, age, growth parameters, spawning, sex ratio, first maturity length and fecundity of gray triggerfish (Balistes capriscus G. 1789) were studied using 195 specimens from the Iskenderun Bay. Females made up 43% and males 57% of the individuals. The total length of females ranged from 8.0 to 24.5 cm and of males from 7.9 to 25.5 cm. The length-weight relationships for male and female were W=0.0386*L2.76 and W=0.0352*L2.78, respectively. The age data, derived from dorsal spin readings, were used to estimate the growth parameters of the von Bertalanffy equation. L8=39.0 cm, K=0.257, to=-0.79. The maximum age group determined was 3 for both sexes. The monthly values of gonadosomatic index (GSI) indicated that the spawning of gray triggerfish occurred mainly between May and July. Gray triggerfish attained first sexual maturity after 1 age (13 cm total length).
