An individual linear growth of 26 specimens of the Anodonta beringiana is studied by measuring of successive annual rings on the surface of the shells. It is shown that the growth of mollusks is well described by the Bertalanffy growth equation. The coefficients of this equation for different individuals do not differ significantly and are on average k = 0.062 ± 0.011 year–1 L∞ = 155.8 ± 19.5 mm. Species lifespan determined by the product of growth constant k and the maximum longevity of mussels in the population is 1.7. This value is close to the average species lifespan of other bivalve species.
