The effects on reproduction were investigated in carp of the Hungarian strain 0 and the Yugoslavian strain J after CPH or Ovopel tratment. After hypophysation eggs were obtained from a similar percentage (~85%) of fish in both strains while after the Ovopel treatment from 100% of females in strain 0 and 50% in strain J. Interaction between the preparation and the provenance of the fish was statistically significant (P ≤ 0.05) for the weight of eggs (in grams and in percentage of female body weight). The highest weight of eggs was obtained after Ovopel treatment of females of strain J and the lowest after CPH application to fish of the same strain (1042.98 g, 15.60% and 746.49 g, 10.97%, respectively). The statistical significance (P ≤ 0.01) of the interaction was noted too for the fertilization percentage; the lowest quality characterized eggs obtained from females of strain J treated with CPH and the highest for eggs of the same strain treated with Ovopel (95.80% and 98.20%, respectively). The effect of latency as an important factor of quality of the eggs obtained after ovulation induction with CPH and with Ovopel from females of the strain 0 was determined. The comparison of reproduction effects of the investigated breeding strains of carp showed that these strains differently respond to the ovulation stimulators applied.

Badano wyniki rozrodu karpia węgierskiej linii 0 oraz jugosłowiańskiej linii J po podaniu samicom CPH lub Ovopelu. Po hypofizacji pozyskano ikrę od podobnego procentu (~85%) ryb z obu linii, natomiast po podaniu Ovopelu od 100% samic z linii 0 i 50% z linii J. Interakcja między podawanym preparatem a pochodzeniem samic była statystycznie istotna (P ≤ 0.05) dla masy ikry (wyrażonej w gramach i w procencie masy ciała samic). Najwyższą masę jaj pozyskano po podaniu Ovopelu samicom linii J, a najniższą po zastosowaniu homogenatu przysadki mózgowej u ryb z tej samej linii (odpowiednio 1042,98 g, 15,60% i 746,49 g, 10,97%). Statystyczną istotność (P ≤ 0,01) badanej interakcji odnotowano dla procentu zapłodnienia; najniższą jakością charakteryzowały się jaja pozyskane od samic z linii J, którym podano CPH, a najwyższą od samic z tej samej linii, którym aplikowano Ovopel (odpowiednio 95,80% i 98,20%). Odnotowano wpływ czasu latencji na jakość ikry otrzymanej po stymulowaniu owulacji CPH i Ovopelem u samic z linii 0. Porównanie wyników rozrodu badanych linii hodowlanych karpia pozwoliło wykazać, że linie te różnie reagują na podanie użytych stymulatorów owulacji.
