Abstract

Based on the biological data of Metapenaeus monoceros collected from shrimp
trawler landings at Cochin Fisheries Harbour during 1991-93, an account on
the reproductive biology of this species is given in this paper. The shrimp is a
continuous breeder with two major spawning periods during December - April
and August - September. The minimum size at maturity in females and males
was 114 and 95 mm respectively. Females in general, outnumbered males and
the average sex ratio of females and males during the period was 57.1 : 42.9.
The mature ova measured between 0.145 and 0.261 mm. Ovary weight in
comparision with total length and total weight was found to be the best fit
against fecundity in M. monoceros.
