NESP MaC Project 3.14 - Assessing changes in black rockcod abundance and size

该记录概述了NESP海洋和沿海枢纽研究计划2023项目“评估黑岩鳕丰度和大小的变化”。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 /> 该项目将评估受威胁的黑岩鳕（Epinealus daemelii）的相对丰度和大小，以告知该物种如何应对保护和管理行动。2010年，在新南威尔士州北方和豪勋爵岛进行了一次大规模调查（81个地点），随后大约每4-5年对这些地点的一个子集进行一次调查。该项目提议对最初的81个基线地点重复进行调查，以评估海洋保护区保护区等保护措施是否有助于恢复黑鳕鱼。总的来说，这将提供一个13年的时间序列（2010 - 2023年），将用于表明黑鳕鱼是否在数量上增加，变得更大，和/或变得更广泛，所有指标都可用于评估正在实施的恢复行动是否有效。<br /> <br /> 输出<br /> ·黑岩鳕鱼的水下视觉普查（UVC）数据[数据集]<br /> ·最终项目报告[书面]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Assessing changes in black rockcod abundance and size". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> This project will assess the relative abundance and size of the threatened black rockcod (Epinephelus daemelii) to inform how the species is responding to conservation and management actions. In 2010, a broadscale survey (81 sites) was undertaken in northern NSW and Lord Howe Island, followed by subsequent surveys of a subset of these sites approximately every 4-5 years. This project proposes to repeat the surveys of the initial 81 baseline sites to assess if protection measures, such as marine protected area sanctuary zones, are assisting in recovery of black rockcod. Overall, this will provide a 13-year time series (2010 – 2023) that will be used to indicate if black rockcod are increasing in abundance, getting larger, and/or becoming more widespread, all indicators that can be used to assess if recovery actions being implemented are effective.<br /> <br /> Outputs<br /> • underwater visual census (UVC) data for black rock cod [dataset]<br /> • Final project report [written]
