The present study was carried out at 22 stations located on the fringing reefs of the island of Mayotte inside the perimeter of the Marine Natural Park of Mayotte (PNMM). The average assessment of the number of samples of marine litter (ML) collected at these stations was 3.9 ± 1.3 ML per 500 m² in winter and 3.8 ± 1.1 ML per 500 m² in summer. Plastic ML was dominant, representing approximately 92% of the litter collected at the stations for the two seasons. The majority was plastic ML from fishing gear (lines, nets etc.). Station 18 presented remarkable average densities of 39 ± 4.2 ML per 500 m² for the two seasons and differed from the other stations in that the ML came solely from the catchment areas, with a majority of aluminium ML (56%). Approximately half the coral colonies coming into contact with ML presented an impact dominated by the category of “Broken or abraded colonies”, with 25% of the colonies being impacted. The colonies most severely impacted by ML were branch or table corals, with the greatest majority for the present study being of the genus Acropora.

本研究是在位于马约特岛海洋自然公园（PNMM）周边马约特岛边缘礁石上的22个站点进行的。在这些站点收集的海洋垃圾（ML）样本数量的平均评估是，冬天每500 m ²为3.9±1.3 ML ，夏天每500 m ²为3.8±1.1 ML 。Plastic ML占主导地位，约占两个季节在车站收集的垃圾的92％。大部分是来自渔具（线，网等）的塑料ML。18号工位的平均密度为每500 m ² 39±4.2 ML这两个季节与其他站点的区别在于ML仅来自集水区，其中大部分是铝ML（56％）。与ML接触的珊瑚群落中，大约有一半受到了影响，以“破碎或磨蚀性殖民地”类别为主，其中25％的殖民地受到了影响。通过ML受影响最严重的菌落是分支或桌面珊瑚，以最大的多数为目前的研究是属的鹿角。
