Fisheries resources of the Benguela Current Large Marine Ecosystem (BCLME) are critically important to the socio-economic well-being of the people of Angola, Namibia and South Africa. Their high degree of environmental vulnerability underscores the importance of maintaining a healthy ecosystem by increasing its resilience to the impacts of anthropogenic and natural forcing. Conflicting objectives in fisheries management processes between the biological sustainability of the stocks and socio-economic gains of the fishers and the economy in general, are some of the challenges facing the BCLME. In this paper, an overview and description of the fisheries yields from major resources of the BCLME is provided, using time series catch data, with discussions on how these are affected by climate variability and/or change. Data were sourced from previous syntheses, reports on the state of fisheries resources, and various national databases. Results indicate that, although major fisheries yields in the BCLME are currently much lower than their historical past, catches have in general been stable during the past two decades. Currently, there appears to be no clear evidence of the impacts of climate change on the fisheries resources in the BCLME, although some changes have been observed, but such impacts may be masked by highly variable and complex nature of this LME. However, through the Benguela Current Convention (BCC), the three coastal states are focused on ensuring that the shared commercially important fish stocks are jointly monitored, assessed and managed, through the implementation of adaptive fisheries management plans for priority shared fish resources based on ecosystem approach to fisheries (EAF) principles.

本格拉当前大型海洋生态系统的渔业产量,气候变化和基于生态系统的管理

Benguela当前大型海洋生态系统(BCLME)的渔业资源对于安哥拉,纳米比亚和南非人民的社会经济福祉至关重要。它们高度的环境脆弱性强调了通过增加其对人为和自然强迫影响的适应力来维持健康的生态系统的重要性。BCLME面临的一些挑战是种群的生物可持续性与渔民社会经济收益之间的渔业管理过程目标矛盾。在本文中,使用时间序列捕获数据,对BCLME主要资源的渔业产量进行了概述和描述,并讨论了它们如何受到气候多变性和/或变化的影响。数据来自以前的综合资料,有关渔业资源状况的报告以及各种国家数据库。结果表明,尽管目前BCLME的主要渔业产量远低于其历史过去,但在过去的二十年中,总体上捕捞量保持稳定。目前,虽然没有观察到气候变化对BCLME渔业资源的影响的明确证据,但已观察到一些变化,但这种影响可能被LME高度可变和复杂的性质所掩盖。但是,通过《本格拉现行公约》(BCC),三个沿海州都致力于确保共同监控,评估和管理共有的具有商业意义的鱼类资源,
