NESP MBH A1 Euryhaline Elasmobranchs Fishing Database

This database contains sampling effort, catch records, biological data, and water quality data for sampling and catches of elasmobranchs in northern Australian rivers, estuaries and coasts undertaken under the National Environmental Research Program (NERP) Marine Biodiversity Hub Project 2.4 'Supporting Management of Listed and Rare Species'. and the National Environmental Science Program (NESP) Marine Biodiversity Hub Project A1 'Northern Australian Hotspots for the Recovery of Threatened Euryhaline Elasmobranchs'. Surveys using gillnets and rod-and-line were undertaken in the Top End region of the Northern Territory and the Kimberley region of Western Australia. Selected animals were tagged for movement ecology, habitat use and mortality estimates (acoustic telemetry), and tissue samples were collected from all fish for molecular analyses (population genetics and close-kin mark-recapture).

本数据库收录了澳大利亚北部河流、河口及近岸海域板鳃类（elasmobranchs）的采样强度（sampling effort）、捕捞记录、生物学数据与水质数据，相关采样与捕捞工作依托两项课题实施：其一为国家环境研究计划（National Environmental Research Program, NERP）海洋生物多样性中心项目2.4《受保护与稀有物种管理支撑》，其二为国家环境科学计划（National Environmental Science Program, NESP）海洋生物多样性中心项目A1《澳大利亚北部受胁广盐性板鳃类恢复热点区域》。本次调查采用刺网（gillnets）与手竿钓法开展，实施区域涵盖北领地（Northern Territory）的顶端地区（Top End region）以及西澳大利亚州的金伯利（Kimberley region）地区。研究人员对选取的个体进行标记，以开展运动生态学、栖息地利用及死亡率估算研究（声学遥测（acoustic telemetry））；同时从所有采集的板鳃类个体中获取组织样本，用于种群遗传学与近亲标记重捕法相关的分子分析。
