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

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. -------------------- 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.
