Cultivation of the flat oyster Ostrea edulis L., which has lost its commercial value due to reduction in abundance, is a relevant task. Simulation models of the flat oyster’s growth can be used to improve oyster cultivation methods. The proposed simulation model of the O. edulis growth dynamics is based on the principles of dynamic energy balance. The model uses approximations of the oyster’s physiological processes (filtration, respiration, excretion, growth, spawning) derived from published observational data. The paper determines functional dependencies of approximation parameters on the environmental conditions. The model was validated using in situ data on the linear and weight growth of the oyster O. edulis cultured in Donuzlav Bay for 30 months from April 2001 to October 2003. The model allowed us to obtain the dynamics of the energy balance components of the flat oyster at different life-cycle stages. The resulting quantitative distribution of growth energy between generative and somatic tissues of the oyster is confirmed by the qualitative description of the oyster’s tissue growth based on in situ measurements. The developed model reproduces well the qualitative and quantitative characteristics of the flat oyster functioning processes. The model of the oyster’s energy balance can be used as a block of a complex ecological model simulating the cultivation of mollusks on an oyster farm.
