| Abstract: | Sillago sihama have a
prolonged breeding season from June to December, with spawning
activity peaked during the
period of September to November. Length at first
maturity stage was found to vary between 155-164 mm (total length) in both
sexes. Although overall sex ratio indicated predominance of female, Chi-square
test (x2) showed no significant difference
throughout the year. Fecundity varied from 11,376 to 103,695 per fish, is significantly
correlated with total length (r = 0.85, r < 0.01), body weight (r = 0.88, r < 0.01) and ovary weight (r = 0.87, r < 0.01). |
