Artisanal fisheries, although considered less harmful, can still endanger marine ecosystems, especially in areas with long-standing tradition. In Cap de Creus, where artisanal fisheries has likely occurred for centuries, the status of benthic communities in fishing grounds was poorly understood. Through collaboration with local fishers, the benthic assemblages in three artisanal fishing grounds within Cap de Creus Marine Protected Area (MPA) were studied. Using video transects recorded by a remotely operated vehicle (ROV), the diversity and distribution of species were analysed in relation to substrate type, slope, and depth. The study also assessed the impacts on these communities by examining marine litter, lost fishing gear, and the condition of gorgonian populations. The findings identified three megabenthic assemblages and revealed higher fishing pressure and impact in the Maça d'Oros area, likely due to multiple fishing guilds converging. However, the study demonstrated lower impact in MPAs compared to unprotected Mediterranean areas, highlighting the importance of coastal management.
尽管手工渔业被认为危害较小，但仍可能危及海洋生态系统，特别是在那些具有悠久传统的地区。在可能已经存在数百年手工渔业的克德克鲁斯角，对渔业区底栖生物群落的状况知之甚少。通过与当地渔民合作，对克德克鲁斯海洋保护区（MPA）内的三个手工渔业区的底栖生物群进行了研究。使用遥控潜水器（ROV）记录的视频横剖线，分析了物种的多样性和分布与底质类型、坡度和水深的关系。该研究还通过检查海洋垃圾、丢失的渔具和柳珊瑚种群的状况，评估了这些群落所受到的影响。研究结果确定了三个大型底栖生物群集，并揭示了马卡多罗斯地区更高的捕捞压力和影响，这可能是由于多个捕捞行会集所致。然而，该研究表明，与无保护的地中海地区相比，MPA 的影响较低，这突出了沿海管理的重要性。
