Abstract

The Acoupa weakfish, Cynoscion acoupa, is an important fishery resource of the Brazilian North coast that is commercially valuable, particularly for its gas bladder (fish maw), which is exported to Asian markets. However, because of intensive fishing and lack of reliable data, the Acoupa weakfish is classified as Vulnerable by the IUCN. We used Fisheries Performance Indicators (FPIs) to evaluate C. acoupa fisheries on the Amazon continental shelf, to inform management actions. The ecological indicator had the lowest score due to increased fishing effort associated with high demand for the fish maw, and the co-management indicator was also unsatisfactory due to the predominance of fishing entrepreneurs and a lack of sustainable management practices. Our findings showed that the C. acoupa fishery is precarious in its sustainability, mainly because of harvest and co-management which were the least satisfactory metrics.

亚马逊大陆架大型阿库帕弱鱼渔业的性能指标

阿库帕弱鱼(Cynoscion Acoupa)是巴西北海岸的一种重要渔业资源，具有商业价值，特别是其气囊(鱼鳔)出口到亚洲市场。然而，由于密集的捕捞和缺乏可靠的数据，阿库帕弱鱼被世界自然保护联盟列为易危物种。我们使用渔业绩效指标(fpi)来评估亚马逊大陆架上的双鳗渔业，为管理行动提供信息。生态指标得分最低，这是由于对鱼肚的高需求增加了捕捞努力，而共同管理指标也不令人满意，因为渔业企业家占主导地位，缺乏可持续的管理做法。我们的研究结果表明，库柏渔业的可持续性是不稳定的，主要是因为收获和共同管理是最不令人满意的指标。

期刊介绍： Fisheries Management and Ecology is a journal with an international perspective. It presents papers that cover all aspects of the management, ecology and conservation of inland, estuarine and coastal fisheries. The Journal aims to: foster an understanding of the maintenance, development and management of the conditions under which fish populations and communities thrive, and how they and their habitat can be conserved and enhanced; promote a thorough understanding of the dual nature of fisheries as valuable resources exploited for food, recreational and commercial purposes and as pivotal indicators of aquatic habitat quality and conservation status; help fisheries managers focus upon policy, management, operational, conservation and ecological issues; assist fisheries ecologists become more aware of the needs of managers for information, techniques, tools and concepts; integrate ecological studies with all aspects of management; ensure that the conservation of fisheries and their environments is a recurring theme in fisheries and aquatic management.
