| Abstract/Description: | From the ova diameter measurements, it has been observed that O. ruber spawns only once a year during July to October, and /. dussumieri spawns twice a year, first between January and February and again between June and September. Indication of sexual maturity is observed in the 170 mm size group in O. rafieranda majority (62.86%) is mature at 200 mm. In /. dussumieri sexual maturity is manifest in the 140 mm size group and a majority offish (51.85%) is mature at 160 mm. Fecundity in the size range of 180-290 mm varies between 44,621 and 179,659 mature eggs in O. ruber, and in /. dussumieri of size range 195-235 mm the number of mature eggs varies between 142,005 and 225,988. |
