In this context, carrying capacity (CC) evaluation of coastal ecosystems for bivalve culture became an important topic. Mathematical modelling is a common approach for CC estimation. The objective of this work is to evaluate the importance of spatial resolution of mathematical models for CC evaluation. Obtained results suggest that low resolution models may lead to CC overestimates.engjournal article
