Description:
Studies indicated spawning season of Nemipterus japonicus off Bombay coast (Maharashtra, India), to be during July to December with peak breeding during November to December. Females attained first maturity at the length range 110-120 mm; 50% maturity and spawning occurred at 135 mm within one year of its age. Overall male: female ratio for the entire period of study was 1:1.01. Relationships of fecundity with total length of fish, total ovary weight and per g. fish weight were worked out as F=(-72674.33) L super(739.73); F =65.44 W super(807.33); F=3112.57 W super(22383.27) and F=467.85 W super(4.96) with coefficient of correlation values (r) 0.9090, 0.9443, 0.9911 and 0.8843 respectively.
