WAMSI Node 3.1.1b and 3.2.2 - Ecosystem Effects of Fishing: finescale coral reef fish surveys Ningaloo Reef, Australia (2006)

From 2006 to 2007 at northern Ningaloo Reef, stereo Baited Remote Underwater Video (stereo-BRUVs) and stereo Diver Operated Video (stereo-DOVs) were used to measure fish assemblages across shallow coral reef lagoon habitats. Four areas were identified including Osprey and Mandu Sanctuary, and Osprey and Mandu Reference Areas which were studied with stereo-BRUV and stereo DOV transects, during two successive summer and winter periods. Each time, six stereo BRUVs and 5 stereo-DOV transects were collected from within 6 coral reef lagoon habitats at 2 well established sanctuary zones and adjacent areas. The video footage was used to create the raw abundance and length data of different fish species.

2006年至2007年，研究团队于宁格罗北礁（northern Ningaloo Reef）开展鱼类群落调查，采用立体诱饵式遥控水下摄像系统（stereo Baited Remote Underwater Video, stereo-BRUVs）与立体潜水员操控式水下摄像系统（stereo Diver Operated Video, stereo-DOVs），对浅海珊瑚礁潟湖生境中的鱼类群落进行量化研究。本次研究共划定4处研究区域，分别为鹗鹰保护区（Osprey Sanctuary）、曼杜保护区（Mandu Sanctuary）、鹗鹰参照区（Osprey Reference Areas）与曼杜参照区（Mandu Reference Areas）；在连续两个夏冬调查周期内，通过stereo-BRUV与stereo-DOV样带完成采样工作。每次调查均在2处既定保护区及其邻近区域内的6个珊瑚礁潟湖生境中，布设6组stereo-BRUV采样单元与5条stereo-DOV样带。所采集的视频影像被用于提取不同鱼类物种的原始丰度与体长数据。
