Survey reveals new habitat for narrow-clawed crayfish in northwestern Russia, suggesting a broader distribution for the species.
The narrow-clawed crayfish, (Eschscholtz, 1823), has been recorded for the first time in the Vyg River basin, White Sea basin, Belomorsky District of the Republic of Karelia, northwestern Russia. The newly identified habitat is located at a considerable distance from the previously known ones in Karelia. The main pathway of river crayfish dispersal is primarily associated with migration activity along watercourses connecting water bodies, mainly during the flood period. A detailed survey of Lake Kosmyusozero is recommended to determine the population density and the survival success of the species in this reservoir.
