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