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.
