This paper describes the first application of the end-to-end model Atlantis in the Strait of Sicily (SoS). The model is designed to simulate ecosystem dynamics under the influence of fishing activities. Model performance was evaluated by comparing predicted biomass and catch of target species against observed data, utilizing multiple quantitative metrics. It reproduces accurately trophic dynamics, and biomass and catch of main target species in the SoS. Sensitivity analysis of the key model parameters identified nutrient loading and fishing pressure as the major processes influencing the ecosystem trophic spectrum and generating bottom-up and top-down effects. The results also emphasized the importance of incorporating uncertainty estimation in model predictions and robust selection of key parameters. The SoS Atlantis represents a strategic tool for the application of Ecosystem Approach to Fisheries Management (EAFM) in the Strait of Sicily and for assessing the effect of alternative management scenarios under a holistic framework.

Atlantis 端到端建模，探索地中海中部西西里海峡的生态系统动态


本文介绍了端到端模型 Atlantis 在西西里海峡 （SoS） 的首次应用。该模型旨在模拟捕鱼活动影响下的生态系统动态。通过使用多个定量指标将目标物种的预测生物量和渔获量与观测数据进行比较来评估模型性能。它准确地再现了 SoS 中主要目标物种的营养动力学、生物量和渔获量。对关键模型参数的敏感性分析确定，养分负荷和捕捞压力是影响生态系统营养谱并产生自下而上和自上而下效应的主要过程。结果还强调了在模型预测中纳入不确定性估计和关键参数稳健选择的重要性。SoS Atlantis 代表了在西西里海峡应用渔业管理生态系统方法 （EAFM） 和在整体框架下评估替代管理方案效果的战略工具。
