For specific data outputs from this project, please see child records associated with this metadata.\nThe Black Rockcod (Epinephelus daemelii) is a large, reef-dwelling species that can live for more than 60 years. In Australia it occurs along the coast of New South Wales, including at Lord Howe Island. Black Rockcod populations have been significantly reduced here due to overfishing, accidental hooking, and loss or degradation of estuarine and intertidal nursery habitats. As a result, the species is listed as Vulnerable under Commonwealth and NSW legislation.\nDespite having been protected from fishing in NSW since 1983, Black Rockcod are still taken illegally, or caught incidentally and released, which can lead to mortality post-release from embolism. Long-term population monitoring is a high priority identified by the species\u2019 recovery plan and the NSW Fisheries Scientific Committee.\nIn 2010, a broadscale baseline survey (81 sites) was undertaken in northern NSW and Lord Howe Island, followed by smaller surveys every four to five years. This project repeated the initial 81 baseline site surveys to assess if protection measures, such as marine protected area sanctuary zones, are assisting in recovery of black rockcod. This contributed to a 13-year time series (2010 \u2013 2023) that was used to examine distribution and population structure of rockcod to assess if recovery actions being implemented are effective.\nOutputs\n\u2022 underwater visual census (UVC) data for black rock cod [dataset]\n\u2022 Final project report [written]", "num_resources": 11, "num_tags": 5, "organization": {"id": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "name": "australian-ocean-data-network", "title": "Australian Ocean Data Network", "type": "organization", "description": "Harvester for Australian Ocean Data Network", "image_url": "", "created": "2025-06-23T12:29:10.320926", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://catalogue.aodn.org.au", "href": "https://catalogue.aodn.org.au/geonetwork/srv/eng/csw/dataset/nesp-mac-project-3-14-assessing-changes-in-black-rockcod-abundance-and-size", "title": "Australian Oceans Data Network"}, "owner_org": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "private": false, "promotion_level": "0", "spatial": "Australia", "state": "active", "temporal_coverage_from": "2023-01-10 00:00:00", "temporal_coverage_to": "2024-06-30 00:00:00", "title": "NESP MaC Project 3.14 - Assessing changes in black rockcod abundance and size", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "670b5af7-d19f-4a10-8759-7b3471b77e98"}, {"key": "harvest_source_id", "value": "a2216e59-91ec-48b1-83cc-d35d9f09fcec"}, {"key": "harvest_source_title", "value": "Australian Oceans Data Network"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-06-23T15:27:19.399913", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Harasti, D., & Malcolm, H.
