Description
Created in November 2020, this infographic explains our research on how acoustic technology like echosounders could be used by purse-seine vessels to fish more selectively at fish aggregating devices (FADs).
Echosounders can be used to identify the acoustic signatures of different tuna species, allowing FAD fishers before they make a set to better target the tuna species whose stocks are at healthy levels — reducing overfishing and bycatch of non-target tuna and other marine species.
