NESP MB Project A14 - Identification of near-shore habitats of juvenile white sharks in Southwestern Australia

本记录概述了国家环境保护计划海洋生物多样性中心项目A14--“确定澳大利亚西南部幼年白鲨的近岸栖息地”的范围和研究成果。有关此项目的特定数据输出，请参阅与此元数据关联的子记录。<br/> <br/> <br/> 2018年初，CSIRO提供了西南部成年白鲨数量的第一次估计。由于缺乏关于澳大利亚西南部青少年生活史阶段的信息，无法确定总丰度的估计值。成人丰度的估计也包括趋势(基本上为零或略为负)，但有人指出，要确认这一趋势，还需要十年的抽样。如果我们确定近岸栖息地，在那里可以很容易地接触到西南部种群的幼年白鲨，这种情况就可以减少。<br/> <br/> 这个试点项目将调查有关幼年白鲨利用大澳大利亚湾源头附近近岸栖息地的可靠轶事证据，并为未来的项目开发步骤提供信息。试点项目将包括与亚塔拉土地管理小组的合作和能力建设机会。该试点项目的结果将通知是否继续进行未来的(水上)活动。<br/> <br/> 计划产量<br/> ·显示幼年白鲨聚集区的空间地图，包括澳大利亚海洋公园的边界和jpeg格式的分区<br/> ·向Erin提供幼年白鲨聚集区的shapefile<br/> ·适合通信目的的高质量和与项目相关的图像(静态和视频)<br/> ·大澳湾海洋公园(英联邦水域)内的投机性野生动物观察摘要(和图片)<br/> ·最终报告

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A14 - "Identification of near-shore habitats of juvenile white sharks in Southwestern Australia". For specific data outputs from this project, please see child records associated with this metadata.<br /> <br /> --------------------<br /> <br /> In early 2018, the CSIRO provided the first estimate of abundance for the southern-western adult white shark. Establishing an estimate of total abundance was not possible due to the lack of information of the juvenile life history stage in south-western Australia. The estimate of adult abundance also included trend (essentially zero or slightly negative), however, it was noted that to confirm the trend, a further decade of sampling would be required. This can be reduced if we identify near-shore habitats where juvenile white sharks from the southern-western population can be readily accessed. <br /> <br /> This pilot project will investigate credible anecdotal evidence of juvenile white sharks using near-shore habitat near the head of the Great Australia Bight, and inform future project development steps. The pilot project will include collaboration and the opportunity for capacity building with the Yatala Land Management group. The outcome of this pilot project will inform whether or not to proceed to future (on-water) activities.<br /> <br /> Planned Outputs<br /> • Spatial maps showing juvenile white-shark aggregation areas that include Australian marine park boundaries and zoning in jpeg format<br /> • Shapefile of juvenile white-shark aggregation areas provided to ERIN<br /> • High quality and project relevant images (still and video) suitable for communications purposes<br /> • Summary (and images) of opportunistic wildlife observations within the Great Australian Bight Marine Park (Commonwealth waters)<br /> • Final report
