Özet
Gametes were collected by abdominal massage from 15 anesthesized male and female grass carp. In collected sperm samples the following mean spermatological properties were determined: sperm volume 15.64 +/- 5.39 mL, sperm motility 81.20 +/- 7.61%, motility duration 62.06 +/- 19.40s, density 17.88 +/- 5.48 x10(9) mL(-1), total density 428.90 +/- 302.05 x10(9), and pH 7.25 +/- 0.81. Also egg size (mm) and fecundity (egg/fish) were determined as 1.04 +/- 0.028 and 417867 +/- 36.274 respectively in female grass carp. The fertilization capacity of sperm was tested with the same egg pool. The insemination dosage was 2x10(5) spz/egg for each fertilization experiment. Fertilization rate was determined as mean 79.3 +/- 2.95% and positively correlated with sperm motility (r=0.932, p<0.01), egg size (r=0.513, p>0.05) and fecundity (r=0.539, p>0.05).
