Title Observations on the biology of Nemipterus
japonicus (Bloch) from Veraval
 
Creator Raje, S G
 
Subject Demersal Fisheries
 
Description The length-weight relationship for Nemipterus japonicus was not significantly
different between sexes, hence the common regression equation for the species
was calculated as log W = 4.88606 + 3.00437 log L. The Kn values were calculated
separately for males and females in relation to various months. Females
attain 50% maturity at 155 mm. Intraovarian investigations indicated that the
spawning period of this species extends from September to April, with a peak
during September-November. The fecundity ranged from 10,260 to 184,960 and
increased with the increase in the length and weight of fish. Sex ratio showed
preponderence of males, with a male to female ratio of 2.2:1. In general, feeding
intensity appeared to increase from September to May. This species is a carnivore,
feeding mainly on crustaceans, teleosts, annelids, molluscs and echinoderms.
