Small-scale fisheries of the Brazilian Atlantic Forest Coast (BAFC) depend on fish resources for food and income. Thus, if the catch diminishes or if fish species that are a target for fishers are overexploited or impacted, this could affect fishers' livelihoods. The exclusion of threatened fish species from the catch is believed to be a threat to small-scale fisheries, which is likely to be the case along the BAFC. Many fish species are currently listed as threatened or vulnerable, whereas there is not enough biological information available to determine the status of the majority of the other species. Failure to protect the BAFC biodiversity might negatively impact fishers' income and the regional economy of local small-scale fisheries. We collected data from 1986 to 2009 through 347 interviews and 24-h food recall surveys at seven southeastern coastal sites of the Atlantic Forest. We show that important species of consumed fish are currently threatened: of the 65 species mentioned by fishers as the most consumed fishes, 33% are decreasing and 54% have an unknown status. Thus, biological and ecological data for BAFC marine species are urgently needed, along with co-management, to promote fish conservation.
巴西大西洋森林海岸(BAFC)的小规模渔业依赖鱼类资源获取食物和收入。因此,如果渔获量减少,或者渔民的目标鱼类物种被过度开发或受到影响,这可能会影响渔民的生计。将受威胁的鱼类物种排除在渔获物之外被认为对小规模渔业构成威胁,BAFC沿岸可能就是这种情况。目前许多鱼类物种被列为受威胁或易危物种,而对于大多数其他物种,没有足够的生物学信息来确定其状况。未能保护BAFC的生物多样性可能会对渔民收入和当地小规模渔业的区域经济产生负面影响。我们通过在大西洋森林东南沿海的七个地点进行347次访谈和24小时食物召回调查,收集了1986年至2009年的数据。我们发现,目前食用的重要鱼类物种受到威胁:在渔民提到的65种最常食用的鱼类中,33%的数量在减少,54%的状况不明。因此,迫切需要BAFC海洋物种的生物学和生态学数据,以及共同管理,以促进鱼类保护。
