Paper deals with characteristics of populations of the narrow-clawed crayfish in the water bodies of Belarus and Armenia. The growth rate, beginning of the sexual maturation and average size of females at 50% maturity in the Belarusian lakes Gin'kovo and Sominskoye and Armenian Sevan Lake were found to be quite comparable. Coupling and oviposition onto the pleopods in the Belarusian population occur in late October − early November, in the Sevan population − in the early April; breeding power of the Sevan population is 1.5 times higher than those of Belarusian. In spite of the all-year intensive commercial catching, average size of the specimens of in the Sevan population is somewhat more than in Belarusian.
