摘要

全球鲨鱼和鳐鱼种群面临的人为压力不断增加,由于缺乏有关其多样性和物种状况的信息,它们的保护和管理可能受到损害。本研究报告对帕劳共和国的鲨鱼和鳐鱼进行了全面审查,利用公民科学、渔业数据和其他科学文献记录了它们的多样性、经济和文化价值以及影响其种群的压力。关于帕劳鲨鱼和鳐鱼的报告包括根据现有的风险评估和它们的生物生产力对风险的初步评估。在帕劳发现了56种鲨鱼和鳐鱼的记录:31种被认为是“确认和验证的”,10种被认为是“需要验证的”,11种被列为“可能的”。另外两个物种被列为“不太可能”,还有两个物种由于分类不清楚而被列为“未知”。生物生产力分析表明,姥鲨(Cetorhinus maximus)的生产力是帕劳鲨鱼和鳐鱼中最低的,而蓝鲨(Prionace glauca)的生产力是最高的。从历史上看,捕鱼死亡是帕劳鲨鱼和鳐鱼面临的最严重威胁,但最近的保护举措有可能大大减少这一威胁,因为在2020年全面实施帕劳国家海洋保护区之后,大片地区已禁止捕鱼。帕劳的鲨鱼具有广泛的社会和文化价值,对旅游业很重要。本研究对包括公民科学在内的现有信息进行了新的综合和概述,但也强调了进一步的地方分类工作和研究的必要性。

The sharks and rays of Palau: biological diversity, status, and social and cultural dimensions
Anthropogenic pressures have been increasing on shark and ray populations globally, and their conservation and management can be compromised by lack of information on their diversity and status of species. This study presents a desktop review of the sharks and rays of the Republic of Palau, drawing on citizen science, fisheries data and other scientific literature to document their diversity, economic and cultural values, and pressures affecting their populations. This account of Palau’s sharks and rays includes a preliminary assessment of risks based-on existing risk assessments, and their biological productivity. Records were found documenting 56 sharks and rays in Palau: 31 species are considered here as ‘confirmed and verified’, 10 species as ‘requires verification’, and 11 species listed as ‘plausible’. An additional two species are listed as ‘unlikely’, and two species is ‘unknown’ due to the taxonomy being unclear. The biological productivity analysis showed that the basking shark (Cetorhinus maximus) had the lowest productivity of Palau’s sharks and rays, while the blue shark (Prionace glauca) showed the highest productivity of species examined. Historically, fishing mortality presented the most significant threat to Palau’s sharks and rays, but recent conservation initiatives have the potential to significantly reduce this threat as large areas are closed to fishing following the full implementation of the Palau National Marine Sanctuary in 2020. Palau’s sharks have a wide range of social and cultural values and are important to tourism. This study presents a new synthesis and overview of available information including citizen science, but also highlights the need for further local taxonomic work and research.
