 Abstract

The effects of short-term storage on the motility and fertilization rate of Barbonymus gonionotus semen were evaluated at different storage period. The best quality semen in terms of spermatological parameters were diluted with 5 different extenders viz. skim milk with fish ringer, glucose based extender, Alsever’s solution, egg yolk citrate and urea egg yolk at a ratio of 1:4, 1:6 and 1:9. Glucose based extender and skim milk with fish ringer solution at 1:4 and Alsever’s solution at 1:9 dilution ratios showed significantly the best equilibrium sperm motility (>80%). Similarly, the highest motility was obtained from semen stored for 30h with glucose based extender in portable ice box with ice at ~2°C. In fertilization trials, Alsever’s solution, glucose based extender and skim milk with fish ringer solution presented 5.85, 33.66 and 9.03% fertilization rate respectively after 24h of storage period compared to fresh sperm. Therefore, it can be concluded that glucose based extender is the best extender than the other extenders used in this study for the short term preservation of silver barb semen.


Key words: Barbonymus gonionotus, short-term preservation, cryo-diluent, equilibrium and post-thaw motility.
