Název v původním jazyce

Growth performance of all-female and mixed-sex common carp (Cyprinus carpio L.) populations in the Central Europe climatic conditions

Popis výsledku v původním jazyce

The results of a 4-yr study focused on comparing growth performance in all-female and mixed-sex populations of common carp are presented. All-female and mixed-sex populations of purebred Northern mirror carp (M72) and scaly crossbreds of female Ropsha (ROP) and male/neomale M72 carp (ROP x M72) were used for this experiment. Average weight and survival after each growing season and slaughtering value after the third and fourth year of the study were measured. While after 8 wk of rearing no differences between all-female and mixed-sex populations were found, the 1-yr-old all-female mirror carp population (M72) gained 29.7% more weight (P < 0.0001) than the mixed-sex (68.5 +/- 15.8 g against 52.8 +/- 13.9 g; mean +/- S.D.) population. After the second, third and fourth year of rearing, live weight was 9.5% (P = 0.0062) and 6.8% (P = 0.0229) and insignificantly 5.1% higher, respectively, in the all-female population. There was no significant difference, even after the fourth growing seaso
