Oratosquilla nepa (Latreilla) is one of the important species of stomatopods landed by the trawlers
at Madras as by-catch. The estimated Bertalanffy parameters of growth (Loc, K and t,) respectively
for males are 96 mm, 2.4871 and —0.07929. Mortality rates were calculated separately for males
and females. As the' b ' values for males and females were not significantly different, the combined
length-weight relationship could be expressed as log W = —4.8665 +2.9661 log L. The length
at first maturity was 73.2 mm for females. Maximum breeding activity was seen during March followed
by June, October, January and December. Estimates of total stock and standing crop are presented
in the paper.
