We studied changes in the respiration rate in five species of freshwater bivalves as a function of animal age and size. The species-specific lifespan was calculated on the basis of the obtained data: Rubner's constant (Ru) and lifespan at standard temperature 20°C (T_20). The longest and shortest lifespan among the studied mollusks was specific for the pearl mussel Margaritifera margaritifera(Ru= 37 kJ and T_20= 36 years) and the freshwater mussel Anodonta anatina(Ru= 8 kJ and T_20= 8 years), respectively.
