Abstract


This study a high white Sailimu salmon sperm basic physiological characteristics , also studied under different osmotic conditions , Na , k , D-glucose , D-fructose , high white salmon sperm activation and rapid movement , the life the impact . System of different osmotic pressure , different solutes on the high white salmon sperm vitality . The test results show that : high white salmon sperm away from the body after 2 ~ 3 h , vitality began a sharp decline . 3 ℃ and 12 ℃ different storage conditions , low temperature 3 ℃ high temperature of 12 ℃ can be better to extend the sperm vitality times . Whitefish average sperm density of 2.78 × 1010 Wei · ml -1 , which is close to most freshwater fish . This requires that the artificial insemination , it is more appropriate to ensure that male and female ratio 1:1 ~ 1.5 . The osmotic pressure level suitable for high whitefish sperm motility at 395.7 kPa ~ 442.3 kPa. Na in the range of 395.7 kPa ~ 442.3 kPa osmotic pressure can significantly extend the time of the rapid movement of high white salmon sperm , significantly extend the life of the time , the maximum value respectively 96.32 s and 143.50 s . 229.4 × 10-3 kPa K can extend the time and the life time of the rapid movement of the white salmon sperm , respectively, while 46.11 s and 90.44 s . 458.8 × 10-3kPa effects substantially equivalent to the deionized water, the osmolality to rise further to start generating the inhibitory effect . In the case of presence of Na , K in the inhibition seems remission, but the data characteristics is not obvious . 395.7 kPa of D-glucose , D-fructose are effective in prolonging the time and the life time of the rapid movement of high white salmon sperm , and also extended compared with Na . This shows that : under suitable osmotic pressure conditions , the sperm can utilize exogenous nutrients for their own use . Sperm in the use of more than two monosaccharides , there are differences.
