| Description |
The length weight relationship of Nemipterus japonicus from Veraval waters is derived to be Log W= -4.7338 + 2.9902 Log L (r =0.9786). Mature females appear in the fishery at 140 mm. The size at first maturity was estimated at 183 mm. Spawning occurs mainly from November to December and in Febru- ary. The females marginally dominated the fishery and the sex ratio between males and females was 1:1.01. The fecundity ranged from 14212 to 46387 and it increased depending upon the size of the fish. Fishes with empty stom- ach occurred in high percentage. This species is a carnivore and feeds on Acetes spp., penaeid prawns, crabs, squilla, squids, juvenile fishes and fish larvae in the order of preference. |
