This study aims to develop and apply a mathematical model for comprehensively assessing the ecological impact of an oyster farm on the coastal waters of the Black Sea through model experiments designed to investigate the interactions between marine farms and the environment. Methods and Results. The oyster farm in Donuzlav Bay was simulated using a two-dimensional chemical-biological object-oriented marine ecosystem model. Numerical experiments simulated the operation of an oyster farm (capacity: ~ 100 tons of wet weight, area: 80 hectares) located in the central part of Donuzlav Bay. Calculations related to oysters in their first, second and third year of cultivation were performed for the period from May to October. Results indicate that during the first year of cultivation, when oyster wet weight of soft tissues ranges from 1.2 to 4.5 g, the farm’s impact on the marine ecosystem is insignificant. In the second and third years of cultivation, an increase in the bottom sediments volume was observed, primarily attributed to the oyster plantation. Conclusions. The simulation results highlight the need to optimize farm configuration and the number of cultivated mollusks to minimize negative impacts on the water area. The qualitative and quantitative characteristics of flat oyster life obtained from the model are consistent with the data from a previously developed one-dimensional mollusk growth model and field data from monitoring the European oyster cultivation in Donuzlav Bay.
