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 x109 mL-1,
total density 428.90±302.05 x109, 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 2x105 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). |
