Abstract
Effects of coelomic fluid on spermatozoa mobility trait, in sturgeons, have not been known well. This research aims to determine the content of inorganic (magnesium, sodium, potassium and calcium) and organic ions (cholesterol and total protein) in coelomic fluid and to investigate the effects of different levels of coelomic fluid on some spermatozoa mobility traits (duration of sperm mobility and the percentage of motile sperms) in Persian sturgeon brood stocks. Hence milts have been sampled from several male brood stocks and have been mixed by oelomic fluid in different ratios (1 to 20, 15, 10, 7.5, 5, 2.5, 1, 0.5, 0.33, 0.25, 0.20 and 0), then mobility traits have been measured by stereomicroscope. Results of this research show that, if coelomic fluid is added to sperm more than 2.5 times, all sperms of Persian sturgeon brood stocks will perish and if coelimic fluid is added to sperm less than 2.5 times, the duration of sperm mobility and the percentage of motile sperms will increase significantly, comparing to controled group (which does not have coelimic fluid) (P<0.05). Besides, the maximum duration of sperm mobility and percentage of motile sperms was respectively observed among those treated groups in which the ratio of coelomic fluid to sperm equaled to 1:0.33 and 1:0.5 (P<0.05).
