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.\n

本数据集的数据来源于2020年7月14日至22日期间，在总长26.2米的商业钩钓渔船‘阿达·克拉拉号’（Fishing Vessel，FV）上开展的声光调查。本次调查区域位于鲨鱼湾伯尼尔岛北部的金鲷（Chrysophrys auratus）禁渔区内，重点聚焦于水深20至70米的子区域——该区域因金鲷向近岸洄游产卵时可形成较高渔获量，故而被选为核心调查区域。本次采集的数据包含：由连接至38/200组合换能器的SIMARD WBT mini型设备录制的.raw格式主动声学文件，以及无诱饵式水下远程视频（Remote Underwater Video，RUV）和下放式相机采集的视频数据。
