Standardised sampling protocols for monitoring fish stocks are essential to assess changes in stock status and provide a means to evaluate the effectiveness of fisheries management measures, such as marine protected areas (MPAs). This study aimed to optimise two standard sampling methods, namely underwater visual census (UVC) and controlled angling ...

Abstract Estimates of reef fish densities made by divers visually censusing 5 m wide strip transects were compared with capture–resight estimates calculated independently using data on the resighting frequencies of fish marked with colour-coded tags.

Accurate, precise, and efficient underwater visual censuses (UVc) are vital for detecting and monitoring range shifts of reef fishes. The present study compared the utility of time-equivalent belt transects and Global Positioning system (GPs)-tracked roaming surveys for assessing populations of range-expanding tropical fishes off southeastern Australia.

Comparing BRUVS and Long-Distance Underwater Visual Census for Monitoring Coastal Fish Assemblages
Coastal ecosystems are subject to intense anthropogenic pressures, requiring robust and efficient monitoring tools to assess fish assemblages and inform conservation strategies. This study evaluated and compared the performance of Baited Remote Underwater Video Systems (BRUVS) and a recently developed Mapping-Tracked Roaming Transect visual census (M ...Alejo J.
