چکیده انگلیسی
In addition, we determined the fertilization rate. Our results show that G. blacodes spermatozoa have a sperm density of 5.35â¯Â±â¯0.16â¯Ãâ¯109 spermatozoa/mL. Sperm motility is initiated on contact with a hyperosmotic swimming medium under normal conditions (1010 mOsm/kg, pH 8 and 8â¯Â°C). The longest motility duration (432.48â¯Â±â¯8.89â¯s) was recorded at 4â¯Â°C. The maximum percentage of motile cells was recorded at 8â¯Â°C (65.66â¯Â±â¯4.95) at osmolality 1010 mOsm/kg, whereas an optimum was observed at pH 8. The fertility rate was 73.9â¯Â±â¯17%. This is the first report on sperm motility of G. blacodes spermatozoa. In conclusion, the results of this study permit a baseline to be established for further research and protocols for artificial reproduction of this species to be developed and optimized. In addition, the information gathered in this research will be useful for developing the biotechnology of Genypterus blacodes.
