Estimating abundance of fish associated with structured habitats by combining acoustics and optics

Data from an acoustic-optical survey conducted from the 14th to 22nd July 2020 onboard the 26.2 m commercial hook and line fishing vessel (FV) Ada Clara. The survey took place within an area closed to fishing for Chrysophrys auratus north of Bernier Island, Shark Bay, focusing on a sub-region in 20-70 m depth, which produces high catches of C. auratus as they migrate inshore to spawn. The collection includes .raw active-acoustic files recorded by a SIMARD WBT mini connected to a 38/200 Combi transducer and video data from and unbaited remote underwater videos (RUV) and drop cameras.
