Schizothorax niger and Schizothorax esocinus are of the cysto-ovarian type, the ova developing within an ovarian sac, and liberated directly to the exterior by means of a small oviduct. The ovaries are thin, small and wine coloured epithelial ridges, microscopic, transparent oogonia are present but not visible to the naked eye. At stage III, the ovaries are large and yellow in colour. The ova are large and at penultimate stage of maturity. The ova diameter varies in different specimens, but one third of the ova being small. In later stages Ovary was thick, translucent and slightly yellowish in colour. The diameter of the ova ranges between 0.5-2.5 mm. During the winter months of January February, March and even April no conspicuous changes are seen. No eggs are exuded by the application of slight pressure on the abdomen. The ovaries are large and jelly like, very much distended and speckled appearance due to large transparent ova. At stage VI. The ovaries are shrunken, flaccid, bag-like and blood-shot. Ovaries are much reduced in volume and thus occupy little space in the body cavity. Some hard, large pale yellow old ova may still persist in the ovary. Fecundity has shown wide fluctuation with time, age, feeding process and season. Absolute fecundity shown by S.niger and S.esocinus reared at site Beerwa under controlled conditions was 1292.5. Where as at Akad was 1328.75 and at Kokernag was 1242.5. On artificial S. niger has shown 1322.5, and S.esocinus has shown 1390.5, respectively.
