A 90 days study was conducted to explore the possibilities of breeding and seed production of Cyprinus carpio using inland saline water of different underground salinities (0, 5, 10 and 15 ppt) in earthen ponds as C. carpio is widely distributed and being a hardy fish able to tolerate salinities of various degree. In the present study, juvenile fishes (30±5.0g) were reared. At the end of trial, the highest weight of matured brooders was found 370±20.00g at 0 ppt followed by 342±26.05g, 275g±15.0g 167.5g±17.50g at 5, 10 and 15 ppt, respectively. The brooders in the ratio of 2 female: 1 male from the different ponds of different salinities were selected, and were placed in spawning tank of salinity regimes for artificial breeding through hypophysation by carp pituitary extract. The rearing medium osmolality and serum osmolality of male and female fish were found to be significant across all treatments at different salinities. The osmolality revealed a gradual increase with an increase in salinity. Maximum growth rate of broodstock, gonad weight, reproductive performance, fecundity, eggs and larvae development were observed at 0 and 5 ppt. The results showed that stripping response, fertilization and hatching rate were significantly (P<0.05) reduced at 15 ppt. Larvae showed high levels of deformity at salinity above 10 ppt (71.21±5.34%). The overall results of the experiment provide an insight that highest larvae survival percentage was 74.28±2.22% at 5 ppt followed by 69.40±1.76%, 49.98±2.04% and 28.78±5.34% at 0, 10 and 15 ppt, respectively. Thus it can be concluded that using 5 ppt of inland saline groundwater can provide the best results for the production C. carpio seed.
