The use of echo-sounder buoys in Mediterranean Sea: A new technological approach for a sustainable FADs fishery

No clear correlation was found between the number of anchored FADs and biomass, while the drifting FADs showed a greater power of attraction than the anchored FADs. Anyway, the echo-sounder buoys may be suitable for future studies. It was highlighted that their simple use in the Mediterranean FADs fishery could facilitate a reduction of the high number of anchored FADs.
