| Abstract |
The goal of this research was to 1) determine the suitability of spermatocrit as a rapid estimator of sperm density and 2) determine whether sperm motility (quality factor) is influenced by sperm density in Atlantic halibut. Sperm density and spermatocrit were determined using hemocytometer and centrifugation, respectively, for 36 milt samples collected from 17 males. Sperm density ranged from 2.0x10 super(11) to 6.1x10 super(11) cells/ml. A relationship was established between sperm density and spermatocrit (r super(2)=0.89, p<0.001), but not between spermatocrit and motility (r super(2)=0.003, p=0.76). Motility ranged from 63 to 155 seconds at spermatocrits of 27 and 69%, respectively. |
