| Description
| - In the course of the past two centuries, attempts were recorded at introducing over 35 non-indigenous fish species in the Czech Republic. Of that number, only 11 species have survived until present. The fully naturalised species that established natural populations include Ameirus nebulosus, Carassius auratus, Gasterosteus aculeatus and Pseurorasbora parva. Occasional and local stable populations are produced by Oncorhynchus mykiss and Salvelinus fontinalis. The occurrence of the remaining species (Aristichthys nobilis, Coregonus maraena, Coregonus peled, Ctenopharyngodon idella and Hypophthalmichthys molitrix) depends on their culture including hand-stripping. On a three-year annual average (2001-2003), the realised production of the alien species in the territory of the Czech Republic attained a total 2037 tonnes. Of the alien species, only C. carassius has shown to be an invasive taxon with a significantly negative impact upon the native ichthyofauna.

- V posledních dvou století byly učiněny pokusy o introdukci více než 35 nepůvodních druhů ryb do přírodních ekosystémů ČR. Z toho pouze 11 druhů se udrželo do současnosti. K úplné naturalizaci včetně vytvoření přírodních populací došlo u druhů Ameirus nebulosus, Carassius auratus, Gasterosteus aculeatus a Pseudorasbora parva. Stabilní přírodní populace lokálně vytváří Onorhynchus mykiss a Salvelinus fontinalis. Výskyt zbývajících druhů (Aristichthys nobilis, Coregonus maraena, Coregonus peled, Ctenopharyngodon idellus a Hypophthalmichthys molitrix) je závislý na jejich chovu včetně umělého výtěru. Produkce nepůvodních druhů dosahovala v tříletém průměru (2001-2003) za rok na území ČR celkem 2037 t. Z nepůvodních druhů se pouze C. auratus projevil jako invazivní taxon, který má negativní dopad na původní ichtyofaunu. V současnosti (s výjimkou Mylopharyngodon piceus) se s dalšími oficiálními dovozy nepůvodních druhů se neuvažuje. (cs)
