The existence of floating marine litter in marine environments enhances the potential for the transport of fouling organisms using these substrates as vectors. In this study, we examined the fouling organisms on different types of litter stranded on two beaches of the Moroccan Mediterranean. The study revealed 13 fouling species belonging to 8 phyla (Arthropoda, Bryozoa, Annelida, Mollusca, Cnidaria, Echinodermata, Chlorophyta, and Ochrophyta) on marine litter. Rafting vectors were almost exclusively made up of plastics and could mainly be attributed to land-based sources. The most common fouling species were the crustacean Lepas pectinata, Lepas anatifera, Perforatus perforatus, and bryozoan species. More taxa were found on large litter than on small litter. Relative substratum coverage was highest for bryozoan sp. (31.0 %), green algae (29.0 %), Lepas anatifera (21.42 %), Lepas pectinata (17.8 %), and Perforatus perforatus (17.46 %). Our results suggest that the growing generation of plastic litter may enhance the probability of the introduction of non-native species into the Moroccan Mediterranean. Therefore, monitoring efforts are needed to identify vectors and the arrival of novel invasive species in this area.
海洋环境中漂浮的海洋垃圾的存在增加了这些基质作为载体传播污损生物的可能性。在这项研究中，我们检查了摩洛哥地中海两个海滩上搁浅的不同类型垃圾上的污损生物。研究揭示了在海洋垃圾上有 13 种污损生物，属于 8 个门（节肢动物、苔藓动物、环节动物、软体动物、刺胞动物、棘皮动物、绿藻和黄藻）。漂流载体几乎完全由塑料组成，主要来自陆地。最常见的污损生物是甲壳类动物藤壶、鳞突滨螺、穿孔滨螺和苔藓动物。大型垃圾上的生物分类更多。苔藓动物 sp. 的相对基质覆盖率最高（31.0%），绿藻（29.0%）、鳞突滨螺（21.42%）、藤壶（17.8%）和穿孔滨螺（17.46%）。我们的研究结果表明，越来越多的塑料垃圾可能会增加非本地物种进入摩洛哥地中海的概率。因此，需要监测工作来识别该地区的载体和新入侵物种的到来。
