Abstract

Small-scale recreational and artisanal fisheries are popular activities in the Autonomous Region of Madeira, and to date no information is available on their impact on regional coastal ecosystems. Through fishers’ surveys and official registers of fish landings, we described and characterized these fisheries in Madeira, comparing artisanal and recreational fisheries. In 2017, artisanal boats landed 91 species in fishing ports, while recreational catches landed 58 species. The most frequent catches were Dentex gibbosus, Phycis phycis and Pagrus pagrus for artisanal fishery and P. pagrus, Serranus atricauda and Diplodus spp. for recreational fishery. Comparing the same techniques, artisanal fishery always showed higher catch per unit effort values than recreational boat fishery. Nevertheless, the low number of artisanal fishery boats in comparison with the recreational ones reflected the lower total landings of the artisanal fishery, which in 2017 were 62.3 t, compared with the 509.8 t estimated catches for the recreational fishery. Though the estimated recreational fishing data were based on surveys and thus subject to various biases, this activity seems to negatively affect coastal ecosystems and, together with artisanal fishing, exerts a combined pressure on targeted species. Improved legislation for both fisheries is essential for an appropriate management of resources.
马德拉岛的小规模渔业:休闲渔业与手工渔业
小规模休闲渔业和手工渔业是马德拉自治区的流行活动,迄今没有关于其对区域沿海生态系统影响的资料。通过渔民调查和鱼类上岸的官方登记,我们描述和描述了马德拉群岛的这些渔业,比较了手工渔业和休闲渔业。2017年,手工渔船在渔港捕获了91个物种,而休闲捕捞捕获了58个物种。捕获最多的是手工渔业的长齿鲨、长齿鲨和长齿鲨,休闲渔业的长齿鲨、非洲Serranus和梁龙。在相同技术的比较中,手工渔业的单位努力渔获量始终高于休闲船渔业。然而,与休闲渔业相比,手工渔业渔船的数量较少,反映了手工渔业的总捕捞量较低,2017年为62.3吨,而休闲渔业的估计捕捞量为509.8吨。虽然估计的休闲捕鱼数据是根据调查得出的,因此受到各种偏差的影响,但这种活动似乎对沿海生态系统产生了负面影响,并与手工捕鱼一起对目标物种施加了综合压力。改善这两种渔业的立法对于适当管理资源至关重要。
