Abstract

Aim: The present study was undertaken to investigate the influence of different salinity levels on gonadal tissue and serum biochemical parameters of Cyprinus carpio reared in inland saline groundwater to standardize the optimal salinity level for better maturation and seed production.

Methodology: A 90 days experiment was conducted in non-drainable rectangular earthen ponds (n= 8) to study the effects of different salinity (0, 5, 10 and 15 ppt) levels on distribution of lipid class profile in Cyprinus carpio reared in inland saline groundwater. Gonads and serum were collected on 15 days interval and lipid classes, cholesterol, phospholipid and triacylglycerol were analyzed by using extracted total lipid.??

Results: The concentration of different forms of lipids were significantly influenced by salinity and their concentration increased with development of maturity stages but lowest level was recorded at ovulation or spermiation stages. It was observed that significantly (p < 0.05) highest level of all lipids was found at 0 and 5 ppt compared to 10 and 15 ppt salinity. ??

Interpretation: The present study revealed that various lipid class fatty acids varied according to salinity and maturity stages of C. carpio in inland saline groundwater. Further, it also indicated that C. carpio has a tendency to adapt, survive, tolerate and reproduce in inland saline environment salinity ranging from 0-15 ppt and was found optimal at 5 ppt based on the reproductive ability. ?????

Key words: Cyprinus carpio, Environmental stress, Lipid profile, Salinity
