Description
| - První populace Carassius auratus, nepůvodního druhu, které postupně po roce 1976 obsadily vody České republiky, byly unisexuální a sestávaly pouze z triploidních samic. Rozmnožovaly se gynogenezí s použitím samců různých kaprovitých druhů. První samci C. auratus v povodí řeky Dyje byly zjištěni po roce 1990. V současné době zastoupení samců ve vzorcích z populací většinou nepřevyšuje 10%, a zdá se, že chybí v některých věkových skupinách. Většina samic je stále triploidních, menší část jsou diploidi a tetraploidní samice se vyskytují pouze ojediněle. Samci jsou většinou diploidní nebo vzácně i triploidní. C. auratus vytvořil v ČR stabilní populace a ve vhodných biotopech se stal dominantním druhem. (cs)
- Initial populations of Carassius auratus, a non-native species that has been increasingly colonising the waters of the Czech Republic since 1976, were unisexual, consisting of triploid females only. They reproduced through gynogeny, utilising males of various cyprinid species. The first males of C. auratus in the River Dyje drainage area were observed after 1990. At present, the representation of males in population samples mostly does not exceed 10% and they appear to be absent fom certain age groups. Most of the females are triploid, a minor proportion is diploid, and tetraploid individuals occur occasionally. The males are mostly diploid or, rarely, triploid. This species has produced stable populations and has become the dominant fish species in suitable habitats.
