In this study, we report the first occurrence of Callinectes sapidus in the rivers of ‘Oued Tani’ (Martil) and ‘Oued Negro’ (Fnideq), based on 127 individuals of the blue crab caught from November 2022 to August 2023. Additionally, we were able to determine the potential consequences of C. sapidus on the indigenous species as well as the socioeconomic implications on artisanal fisheries activities. This research highlights further data that reinforces recent findings on recorded blue crab from various locations along the Moroccan coastline.

入侵性蓝蟹 Callinectes sapidus Rathbun, 1896（十足目，梭子蟹科）正在摩洛哥地中海西北部海岸迅速扩大其分布范围

在这项研究中，我们根据 2022 年 11 月至 2023 年 8 月捕获的 127 只蓝蟹，报告了“Oued Tani”（Martil）和“Oued Negro”（Fnideq）河流中首次出现的 Callinectes sapidus。我们能够确定 C. sapidus 对本地物种的潜在影响以及对手工渔业活动的社会经济影响。这项研究强调了进一步的数据，这些数据强化了摩洛哥海岸线沿线不同地点记录的蓝蟹的最新发现。
