项目摘要

The angel shark family (Squatinidae) is one of the most threatened chondrichthyan families globally, and Squatina squatina (Angelshark) is listed as Critically Endangered on the IUCN Red List of Threatened Species. Once widespread across the northeast Atlantic and the Mediterranean and Black Seas, overexploitation and coastal habitat degradation have driven drastic range contractions. Angelsharks are now limited to a few small, fragmented populations. Due to their low numbers, there remains a distinct lack of data on the life history, distribution, movement ecology and habitat requirements of Angelsharks, and further research is essential and urgent to guide policy and support conservation decision making. This project will address critical knowledge gaps in the spatial and behavioural ecology of adult Angelsharks in the Canary Islands, a unique stronghold for this species. Acoustic telemetry will be utilised in order to provide detailed, long-term and round-the-clock ecological data from La Graciosa Marine Reserve. Spatial network analyses will be used to investigate site fidelity, space-use, habitat preference and distribution drivers. Crucially, the data and findings from this project will be used to inform effective protection of Angelsharks, with the aim of securing the future of the species in the Canary Islands and further afield.

天使鲨科（Squatinidae）是全球最受威胁的软骨鱼科之一，而天使鲨（Angelshark）在国际自然保护联盟濒危物种红色名录中被列为极度濒危物种。曾经广泛分布于东北大西洋、地中海和黑海，但过度开发和沿海栖息地退化导致范围急剧缩小。天使鲨现在仅限于少数小而分散的种群。由于数量较少，有关天使鲨的生活史、分布、运动生态和栖息地要求的数据仍然明显缺乏，进一步的研究对于指导政策和支持保护决策至关重要且紧迫。该项目将解决加那利群岛成年天使鲨空间和行为生态学的关键知识差距，加那利群岛是该物种的独特据点。将利用声学遥测技术提供来自拉格拉西奥萨海洋保护区的详细、长期和全天候的生态数据。空间网络分析将用于调查场地保真度、空间利用、栖息地偏好和分布驱动因素。至关重要的是，该项目的数据和调查结果将用于为天使鲨的有效保护提供信息，以确保加那利群岛和更远地区该物种的未来。
