The males were more abundant in smaller size groups, but attained 1 : 1 sex ratio
with growth. The mean lengths at maturity for males and females were 16 and
21 cm respectively. The absolute fecundity was estimated to be 12300-955000 for
fish ranging in total" length from 16 cm to 30 cm. The food consisted mainly of
