Abstract :

Abstract[1]Different factors such as the quality of ova and sperm are involved in propagation process. Mobility percentage, pH, mobility duration, compaction and osmolarity of sperm which affect the quality of sperm were tested in this research. This study was carried out in April 2011 in Shahid Ansari Bony Fishes Propagation and Rearing Center. According to the results, mean and standard deviation of ions in 3 and 4 years old fish were 329.6±11.9 and 343.4±11.9 osmolarity, 47.2±7.4 and 44.5±2.99 spermatocrit, 60.5±12 and 66.3±6.1 mobility duration, 80±6.7 and 83.5±3.9 mobility percentage, 17828750±3199657.8 and 18000000±2090454.5 compaction of sperm and 7.79±0.51 and 7.61±0.26 pH of sperm. The correlation between osmolality, mobility percentage, mobility duration and compaction of sperm with parameters of artificial propagation efficiency (fertilization percentage and hatching rate) was investigated positive, significant and direct.   * Corresponding Authors; Email: [e-mail]
