Description	Carassius gibelio is non-indigenous to the ichthyofauna of the Czech Republic. The first specimens penetrated into the area of confluence of the Morava and Dyje rivers in 1975-76. Over 15 years silver crucian carp populated all suitable aquatic habitats. Until the 1990s, the population this species consisted of females only and the reproduction was realised through so-called gynogeny connected with sexual parasitism against males of other cyprinids. First males we found in 1995, their representation in our samples varying between 0 and 18.5%. Our investigations have shown that, besides largely triploid individuals (almost exclusively females ones), there also occur diploid ones (males and some of females) and, occasionally, even tetraploid ones (females). In some habitats the high abundance and biomass of C. gibelio exerts a negative influence on the occurrence of indigenous species mainly, C. carassius and Tinca tinca.
