The present study was conducted to investigate the fecundity and gonadosomatic index of a carp species, Cirrhinus mrigala (Hamilton)
reared under semi-intensive culture conditions in earthen pond. Mean
body weight of fish was 840.6+48.3g and mean total length of fish was
42.15+0.89cm (n=25). Mean ovary weight was 140.28+9.17g. Mean
number of eggs in ovary were 942.6+13.9. The absolute fecundity was
132,129+8481 which ranged from 34,122 (in 342g fish) to 228,000 (in
1133g fish). The relative fecundity was 155,879+ 6269. Eggs/kg ovary
were estimated as 942613. The relationships between fecundity and fish
total length, fish weight and ovary weight were linear. The correlation
coefficient (r) of fecundity and total length (0.543); fecundity and fish
weight (0.648) and fecundity and ovary weight was 0.950. The ovary
weight is better index of fecundity estimation than other body parameters. The GSI ranged from 9.65 to 22.62 observed in July.
