Abstract
Fecundity indices were estimated in
order to find the trends in fecundity with
increase in length and weight of spawners.
The different indices calculated were relative
fecundity (Bagenal, 1957, De Silva,
1973), number of ova per gram ovary
weight, coefficient of maturity (Nikolsky,
1961) and gonosomatic index. The number
of ova per gram weight of fish varied from
287 to 587 with a mean value of 442, while
the number of ova per gram ovary weightranged between 3533 and 7659 with 6120
as average. The coefficient of maturity
values were found to vary from 5.72 to 9.07
(average 735) and gonosomatic index from
6.07 to 9.98 (average 7.95).
