Mussel farming is the main economic activity in Bizerte Lagoon, with a production that fluctuates depending on environmental factors. In the present study, we apply a bioenergetic growth model to the mussel Mytilus galloprovincialis, based on dynamic energy budget (DEB) theory which describes energy flux variation through the different compartments of the mussel body. Thus, the present model simulates both mussel growth and sexual cycle steps according to food availability and water temperature and also the effect of climate change on mussel behavior and reproduction. The results point to good concordance between simulations and growth parameters (metric length and weight) for mussels in the lagoon. A heat wave scenario was also simulated using the DEB model, which highlighted mussel mortality periods during a period of high temperature.
贻贝养殖是比塞大泻湖的主要经济活动，其产量随环境因素而波动。在本研究中，我们根据描述贻贝体内不同隔室能量通量变化的动态能量预算（DEB）理论，将一个生物能量生长模型应用于贻贝 Mytilus galloprovincialis。因此，本模型根据食物供应和水温模拟贻贝的生长和性周期步骤，同时还模拟了气候变化对贻贝行为和繁殖的影响。结果表明，模型模拟与泻湖贻贝的生长参数（度量长度和重量）之间具有良好的一致性。还使用 DEB 模型模拟了一个热浪情景，该情景突出了高温期间贻贝死亡的时期。
