Online published on 14 August, 2019. Abstract The sperm quality of Cyprinus carpio var. communis in farmed conditions was undertaken by studying the physical and biochemical parameters which are taken as indicators of evaluating the good quality seed. The analysis of sperm characteristics also provides a reasonable basis for developing a strategy for maximizing the fertility of a fish. A total of 30 matured fish samples were taken for the present study. During the present study physical analysis showed a mean sperm volume of 1.486±0.17, mean sperm motility of 68.9± 2.27%, mean movement duration of 44.66±2.46s, mean sperm density of 3.84±0.031109/ml, and mean pH of 8.5±0.051. Glucose, total protein, triglyceride and urea were found to be 85.06 ± 9.29mg/dl, 0.917±0.62g/dl, 12.3±5.22 mg/dl and 28.4±4.47mg/dl respectively in the fish in captive culture conditions. A significant positive correlation was found between the sperm volume & motility and pH & motility. Higher concentration of glucose and urea in the farmed individuals is believed to be caused by a wide range of environmental stressors. This information will be of utmost importance in developing cryopreservation procedures, to meet species-specific extender requirements, and also to optimize artificial fertilization procedures in Common carp, Cyprinus carpio var. communis.
