Based on our discussions with fishermen and analysis of catches from professional fishing, this work confirms the presence of the American blue crab Callinectes sapidus in the southwest Mediterranean and highlights its invasion of Mellah lagoon in Algeria. The number and frequency of occurrence of this species in fishing gear (up to 10 individuals per fyke net), the presence of juveniles and ovigerous females as well as its presence in the local market, show that it is well established. The possible impact of C. sapidus on the local environment and native species, and the prospects for its fishing exploitation are discussed in the light of the current knowledge.
基于我们与渔民的讨论和对专业捕捞渔获物的分析，这项工作证实了美洲蓝蟹 Callinectes sapidus 存在于地中海西南部，并强调了它对阿尔及利亚 Mellah 泻湖的入侵。这种物种在渔具中的数量和出现频率（每只刺网多达 10 只）、幼体和抱卵雌体的存在以及它在当地市场上的存在，表明它已经很好地建立起来。根据目前的知识，讨论了 C. sapidus 对当地环境和本地物种的可能影响，以及对其捕捞利用的前景。
