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 Marine和Coastal Hub研究 - 项目3.11-多渔业合作，以评估澳大利亚北部受威胁的锯鱼的人口丰度和后发行后的生存。有关此项目的特定数据输出，请参阅与此元数据相关的子记录。<br /> <br /> 为了改善锯鱼的报告并获得对锯鱼抽象和库存结构的估计，提出了一个大规模的合作项目，在行业，州和联邦机构之间，以及领导研究机构，以收集来自北澳大利亚北部的组织样本。该项目将着重于在研究和商业捕鱼行业之间发展信任，这将实现以下各个方面：<br /> <br /> - 行业领导的报告和抽样计划将在整个澳大利亚的北部渔业中建立。 <br /> - 组织样品将用于使用近亲标记重新调整（CKMR）评估锯鱼抽象和库存结构。 <br /> - 释放后存活率的估计将从卫星标签和改进的报告中获得。 <br /> - 关于抽象和发布后生存的数据将用于评估锯鱼兼例的可持续性。 <br /> <br /> 该研究还旨在改善北澳大利亚渔业中其他EPBC列出的物种的锯鱼报告。如果收集了足够的组织样品，近亲马克的重新捕获将使四种锯鱼的成人人口大小估计。释放后的生存和抽象估计将用于确定在州，领土和联邦渔业中被捕获为副捕捞的锯鱼的可持续性。改进的旁观估计值，人口连通性，成人抽象和释放后生存量被确定为Sawfish和River Shark Multispecies恢复计划中最高的研究优先事项。 <br /> <br /> 在澳大利亚，根据《 EPBC法》（Pristis Pristis，P。Zijsron和P. clavata）列出了四个发生的物种中的三个。第四种澳大利亚物种，狭窄的锯鱼（Anoxypristis cuspidata）被列为迁徙物种。根据《 EPBC法》，cuspidata和P. pristis目前都被提名为濒危。威胁物种策略中还列出了淡水锯鱼pristis pristis-鱼类的100种优先物种。 <br /> <br /> 计划输出<br /> •Sawfish捕获数据[空间数据集] <br /> •组织样品和测序数据<br /> •最终技术报告，分析的数据和对关键发现的政策制定者的建议简要摘要[书面]
