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]

本记录概述了NESP海洋和沿海枢纽研究-项目3. 11-多渔业合作，以评估人口丰度和释放后生存的受威胁的锯鳐在北方澳大利亚。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 /> 为了改进锯鳐报告和获得锯鳐丰度和种群结构的估计，提议在工业、州和联邦机构之间开展一个大规模的合作项目，并牵头研究机构从澳大利亚北方各地收集组织样本。该项目将侧重于发展研究与商业捕鱼业之间的信任，以实现以下目标：<br /> <br /> - 将在整个澳大利亚北方渔业建立行业主导的报告和取样方案。<br /> - 组织样本将用于评估锯鳐丰度和股票结构，使用近亲属标记-重新捕获（CKMR）。<br /> - 将通过卫星标记和改进的报告来估计释放后的存活率。<br /> - 关于丰富度和释放后存活率的数据将用于评估锯鳐副渔获物的可持续性。 <br /> <br /> 该研究还旨在改善沿着其他EPBC列出的物种在北方澳大利亚渔业的报告。如果收集到足够的组织样本，近亲标记重捕将使四种锯鳐的成年种群规模的估计。释放后的生存和丰富的估计将用于确定可持续性的锯鳐捕获作为副渔获物在国家，领土和英联邦渔业。改进对副渔获物、种群连通性、成鱼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计划的最高研究优先事项。<br /> <br /> 在澳大利亚境内，四个物种中有三个被EPBC法案列为易危和迁徙物种（Pristis pristis，P. zijsron和P. clavata）。第四个澳大利亚物种，窄锯鱼（Anoxypristis cuspidata）被列为迁徙物种。A.目前，根据EPBC法案，尖吻和P. pristis被提名为濒危物种。淡水锯鱼Pristis Pristis也被列入受威胁物种战略- 100种优先鱼类。<br /> <br /> 计划产出<br /> ·锯鳐渔获量数据[空间数据集]<br /> ·组织样本和测序数据<br /> ·最后技术报告，包括分析数据和为决策者提供的关键调查结果的建议的简短摘要[书面]
