Acoustic tracking and population assessment of White Sharks (NESP MBH A3)

White sharks are listed as vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and actions to assist their recovery and long-term viability are prescribed in a national recovery plan for the species.A priority action is to develop an effective means of estimating the size of white shark populations and monitor their status (population trend). This would provide a scientific basis for assessing recovery actions, and for local policies governing human-shark interactions: an issue of significant public concern.NESP Project A3 provides a national assessment of the southern-western adult white shark population abundance and an update of the total eastern Australasian white shark population abundance and status in order to establish the efficacy of existing recovery actions and provide a scientifically sound and rational basis from which to inform policies that aim to balance conservation objectives and public safety.This record describes white shark distribution and movement through the use of acoustic and electronic tags fitted to approx. 70 animals.Tag detection data are continually uploaded to the IMOS Animal Tracking Facility (ATF) database. This data collection has been granted Protected Species Status and access to the data is currently restricted.

根据《1999年联邦环境保护与生物多样性保护法》，大白鲨被列为易危物种，针对该物种的国家恢复计划中已明确助力其种群恢复与长期存续的相关行动方案。当前的一项优先行动是研发有效的大白鲨种群规模估算方法，并对其种群状态（种群趋势）开展监测。此举可为评估恢复措施以及制定管控人鲨互动的地方政策提供科学依据——人鲨互动是广受公众高度关注的议题。NESP项目A3针对澳大利亚西南部成年大白鲨的种群丰度开展全国性评估，并更新澳大利亚东部海域大白鲨的总种群丰度与种群状态，旨在验证现有恢复措施的有效性，并为制定兼顾保护目标与公共安全的政策提供科学合理的决策依据。本数据集通过为约70头大白鲨植入声学与电子标签的方式，记录其分布与移动轨迹。标签检测数据会持续上传至IMOS动物追踪设施（Animal Tracking Facility, ATF）数据库。该数据集采集工作已获得保护物种资质，当前数据访问权限受到限制。如需了解数据获取的更多相关信息，请查阅本记录中列出的联系人详情。
