ABSTRACT :

The Chagos Marine Reserve, central Indian Ocean, was declared in part to convey protection to large migratory fish including tuna. In order to determine the extent to which this objective can be met, it is necessary to evaluate the abundance of such inside the Reserve. Fishing methods are inappropriate inside a Marine reserve, so alternative fisheries-independent methods are required. Here we report on cross-comparison studies with baited remote underwater cameras (BRUVs) and scientific echosounders conducted around Chagos in January 2015. Our analyses show close agreement between techniques, which opens the way for continuous acoustic-based monitoring of fish throughout the archipelago from the Pacific Marlin support vessel undertaking logistic and patrol duties.
