Abstract: Observations on the sex ratio and fecundity of Sillago sihama have been made in this report. By the help of these observations we can say that the female to male ratio was found to be 1: 1.3 i.e. males are comparatively more abundant in small size groups. Mean fecundity was found to be 58781, the minimum and maximum being 5483 and 63244 from the fish measuring 180 – 189 mm T.L to 270 – 279 mm T.L respectively. Right lobe was found to be more fecund than the left one. The results will help to increase our knowledge of reproduction biology of Sillago sihama which can be utilize in aquaculture management and breeding programmes.
