海山、深海珊瑚和渔业——普遍存在的海底特征、重要的海洋生态系统和重要的人类活动:它们共同造成了最关键的海洋问题之一。该报告揭示了全球范围内海山栖息地石珊瑚以及相关海洋生物多样性和组合对拖网捕捞影响的脆弱性,特别是在国家管辖范围以外的区域。它提供了迄今为止最好的一些科学证据,支持在公海采取协调一致的紧急行动的呼吁,以保护海山群落及其相关资源免受深海捕捞的不利影响。报告介绍了数据分析的结果,这些数据分析用于了解深海珊瑚在海山上的全球分布、模拟石珊瑚适宜栖息地的分布以及了解国家管辖范围以外区域海山拖网渔业的范围。将这些结果与拖网捕捞对珊瑚和其他海山物种影响的知识结合起来,以确定因当前和未来拖网捕捞对公海的影响而面临风险的主要区域。特别是,印度洋、北大西洋、南大西洋以及南太平洋的海山生态系统受到金目鲷(250-750 米)和橙罗非鱼(750-1200 米)渔业扩张的威胁。
Seamounts, deep-sea corals and fisheries - an ubiquitous ocean floor feature, a key marine ecosystem, and an important human activity: together they have created one of the most critical ocean issues. The report reveals the global scale of the vulnerability of habitat-forming stony corals on seamounts, and that of associated marine biodiversity and assemblages, to the impacts of trawling, especially in areas beyond national jurisdiction. It provides some of the best scientific evidence to date to support the call for concerted and urgent action on the high seas to protect seamount communities and their associated resources from the adverse effects of deep-water fishing. The report describes the results of data analyses that were used to understand the global distribution of deep-sea corals on seamounts, to model the distribution of suitable habitat for stony corals, and to appreciate the extent of the trawl fisheries on seamounts in areas beyond national jurisdiction. These results were combined, along with knowledge of the effects of trawling on corals and other seamount species, to identify the main areas at risk from the impact of current and future trawling on the high seas. In particular, seamount ecosystems in the Indian, North and South Atlantic, and the South Pacific Oceans, are threatened by the expansion of alfonsino (250-750 metres) and orange roughy (750-1200 metres) fisheries.;
