The objective of this study was to investigate the effects of extenders and storage time on motility, viability and fertilization of preserved black sharkminnow, Labeo chrysophekadion spermatozoa. Sperm were diluted 1:3 in one of five extenders: modified Cortland solution (MC); Hanks' balanced salt solution (HBSS); 0.9% sodium chloride (NaCl); Kurokura solution (KU); and modified extender, and undiluted sperm samples were used as control and stored at 4°C for 5 days. Motility, viability and fertilization rates were evaluated every day. After a storage time of three days, the highest motility, viability and fertilization rates (61.27 ± 2.26%, 58.60 ± 2.29% and 40.58 ± 0.57, respectively) were achieved with sperm diluted with modified extender. Motility, viability and fertilization rates decreased significantly (P < 0.05) with increasing storage time in all treatments. In addition, this study found that motility, viability and fertilization had a positive significant correlation (P < 0.01). The results indicate that isotonic extender is suitable for the short‐term preservation of black sharkminnow spermatozoa. 相似文献
