Effect of different salinities on breeding and larval development of common carp, Cyprinus carpio (Linnaeus, 1758) in inland saline groundwater

Abstract A 90 days experiment was conducted to study the effect of different salinities (0, 5, 10 and 15 ppt) on breeding and larvae development of Cyprinus carpio using inland saline groundwater (ISGW). At the end of the experiment, average weight of the matured brooders were 370 ± 20 g, 342 ± 26 g, 275 ± 15 g, 167.5 ± 17.50 g at the salinities of 0, 5, 10 and 15 ppt, respectively. Among different salinities, relatively high gonad weight, fecundity, sperm motility, fertilization rate, embryonic and larval development was observed at the salinities of 0 and 5 ppt. The results showed that the stripping response, latency period, fertilization, and hatching rate were significantly (P
