|Abstract:||Present paper deals with several aspects of reproductive biology viz., maturity of gonads, gonado somatic index (GSI), size at first maturity and fecundity of striped grouper off Visakhapatnam, middle east coast of India. A few species of groupers follow a gonochoric sexual pattern where individuals function either as male or female without post-maturational sex change. Based on present study, striped grouper has been diagnosed as functionally gonochoric. 273 specimens were histologically tested for sex determination. Results of calculates gonadosomatic (GSI) index showed that maturation occurred from November to March with a peak in February. Size distribution and size at sexual maturity calculated as 660 mm TL for males and 610 mm TL for female. Fecundity was estimated from 37 specimens of length range 543 to 885 mm TL, number of ova ranged from 1,53,419 to 37,72,37,72,803 with an average of 18,68,589.|
