Popis: The trends in the distribution and occurrence of the freshwater crayfish in the water bodies of the Neman River basin are presents. It has been shown that both native species: the noble and the narrow-clawed crayfish are declined and/or are displaced with rapidly expanding its range the invasive spiny-cheek crayfish. In recent years the alien species was found in isolated gravel pits and lakes, where it could be transferred only by the human activity. These findings confirm the need of the education about the threats posed by the invasive species on the native biodiversity especially with the local community, which is an obligatory practice for protection the native species in the area expanded with non-native crayfish species. Further, to increase the likelihood of the local biodiversity conservation it is highly needed to undertake targeted actions aimed at resettling endangered populations into waterbodies unavailable for the invasive spiny-cheek crayfish expansion.
