This record provides an overview of the NESP Marine and Coastal Hub study - Project 3.11 - Multi- fishery collaboration to assess population abundances and post release survival of threatened sawfish in northern Australia. For specific data outputs from this project, please see child records associated with this metadata.<br /> <br /> To improve sawfish reporting and obtain an estimate of sawfish abundance and stock structure, a large-scale collaborative project is proposed between industry, State and Commonwealth agencies and lead research institutions to gather tissue samples from across northern Australia. The project will have a focus on developing trust between research and the commercial fishing industry that will achieve the following:<br /> <br /> - Industry led reporting and sampling programs will be established throughout Australia’s northern fisheries. <br /> - Tissue samples will be used to assess sawfish abundance and stock structure using Close-Kin Mark-Recapture (CKMR). <br /> - Estimates of post-release survival will be obtained from satellite tagging and improved reporting. <br /> - Data on abundance and post release survival will be used to assess the sustainability of sawfish bycatch. <br /> <br /> The research also aims to improve reporting of sawfish along with other EPBC listed species in northern Australian fisheries. If enough tissue samples are collected, close kin mark recapture will enable estimates of adult population size for four species of sawfish. Post release survival and abundance estimates will be used to determine the sustainability of sawfish captured as bycatch in state, territory and Commonwealth Fisheries. Improved estimates of bycatch, population connectivity, adult abundance and post release survival were identified as the highest research priorities in the Sawfish and River Shark multispecies recovery plan. <br /> <br /> Within Australia, three out of the four occurring species are listed as Vulnerable and Migratory under the EPBC act (Pristis pristis, P. zijsron and P. clavata). The fourth Australian species, narrow sawfish (Anoxypristis cuspidata) is listed as a Migratory species. Both A. cuspidata and P. pristis are currently under nomination to be up-listed to Endangered under the EPBC act. The Freshwater Sawfish Pristis pristis is also listed in the Threatened Species Strategy - 100 priority species for fish. <br /> <br /> Planned Outputs<br /> • Sawfish catch data [spatial dataset]<br /> • Tissue samples and sequencing data <br /> • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written]

该记录概述了 NESP 海洋和沿海中心研究 - 项目 3.11 - 评估澳大利亚北部受威胁锯鳐的种群丰度和释放后生存情况的多渔业合作 有关该项目的具体数据输出，请参阅与相关的子记录。此元数据。<br /> <br/> 为了改进锯鳐报告并获得锯鳐丰度和种群结构的估计，行业、州和联邦机构以及主要研究机构提出了一个大型合作项目，从澳大利亚北部收集组织样本。发展研究与商业捕鱼业之间的信任，这将实现以下目标：<br /> <br/> - 澳大利亚北部渔业将建立行业主导的报告和采样计划<br /> - 组织样本将用于使用近亲标记重新捕获 (CKMR) 评估锯鳐丰度和种群结构<br /> - 释放后生存率的估计将通过卫星标记和改进的报告来获得。 - 丰度和释放后存活率的数据将用于评估锯鳐兼捕的可持续性<br /> <br/> 该研究还旨在改善锯鳐以及澳大利亚北部渔业中其他 EPBC 列出的物种的报告，如果收集到足够的组织样本，近亲标记重新捕获将能够估计四种锯鳐的成年种群规模。将用于确定州、领地和联邦渔业中作为兼捕捕获的锯鳐的可持续性。改进对兼捕、种群连通性、成年丰度和释放后存活率的估计被确定为锯鳐和河鲨多物种恢复的最高研究优先事项。计划。 <br/> 在澳大利亚，根据 EPBC 法案，四种现存物种中的三种被列为易危和迁徙物种（Pristis pristis、P. zijsron 和 P. clavata）。第四种澳大利亚锯鳐 (Anoxypristis cuspidata) 被列为迁徙物种。目前，A. cuspidata 和 P. pristis 均已根据《淡水锯鳐》法案被提名为濒危物种。 pristis 也被列入受威胁物种战略 - 100 种优先鱼类物种<br /> <br/> 计划产出<br /> • 锯鳐捕获数据[空间数据集]<br /> • 组织样本和测序数据<br /> • 最终技术报告，其中包含分析数据以及针对主要发现的政策制定者的建议简短摘要[书面]
