Determination of the best post-ovulatory stripping time for the common carp (Cyprinus carpio Linnaeus, 1758)

Popis výsledku v původním jazyce

To determine the best time interval between ovulation and controlled egg stripping in female common carp (Cyprinus carpio), ovulated eggs were retained at 20 degrees C inside the fish body until 12-14h post-ovulation (HPO). The eggs of four females werestripped with two-hour intervals after ovulation for 12-14 HPO and fertilized with mixed milt obtained from three males. Eyeing, hatching and eyed-egg mortality rates as well as the occurrence of larval malformations and ploidy anomalies were consideredas indices to assess egg quality. The results indicated that throughout 4-6 HPO the eyeing and hatching rates remained approximately 90 and 80% of the initial rates, respectively. Although not significantly different (P>0.05), the viability rates (eyeingand hatching percentages) increased to about 7.5% of the initial rates at 2-4 HPO compared with 0-2 HPO. Thereafter, the eyeing and hatching rates decreased over time linearly and finally dropped to 11 and 2.5% in eggs fertilized at 12-1
