Black rockcod Underwater Visual Census (UVC) data from northern NSW and Lord Howe Island 2023-24 (NESP MaC 3.14), Tasman Sea, Australia

Broadscale surveys of black rockcod were first conducted using the diver Underwater Visual Census (UVC) technique in 2009-11 when 83 sites were sampled from Port Stephens to Cook Island in far northern NSW, including the waters of Lord Howe Island. The NESP Marine and Coastal Hub project 3.14 (https://www.nespmarinecoastal.edu.au/project/3-14/) funded the repeat of these broadscale surveys in 2023, with 8 additional sites (91 total) sampled using the same technique.
