Abstract

Male and female Paiapenaeopsis sculptilis in the fishery registered monthly
average growths of 5.88 mm and 8.17 mm, respectively. The young prawns recorded
faster rate of growth, about 15 mm per month. In the inshore fishery the
smallest female with fully matured ovary measured 88 mm in length, whereas in
the Arnala creek the prawns measuring 71 mm and above were found to be mature.
Spawning is year-round with two peaks, one during February-March and
another during July-November. The chi-square values at 5% probability level
showed that the observed proportion of males in difi'erent months of the years
except 1969 were statistically significant. Sizewise distribution of sex ratio revealed
that males were predominant in the sizes within 78-98 mm and females outnumbered
males in the rest of the sizes.
