Here we analysed more than 80,000 dFAD trajectories (56,263 tracking buoys) in the Indian and Atlantic oceans from 2012 to 2018. We found that more than 40% of dFAD trajectories ultimately drifted away from fishing grounds, becoming ALD. About 20% of these lost dFADs passed within 50 km of major ports, indicating that port-based programmes could be effective in collecting ALD dFADs at sea. We also identified areas within the fishing grounds where most dFADs exit and where high-seas recovery could be valuable. For example, most dFADs leaving Indian Ocean fishing grounds along their eastern border at similar to 70 degrees E, particularly in October-December, do not return to fishing grounds. Despite considerable logistical challenges, at-sea dFAD recovery offers promising options for reducing the ecological footprints of purse-seine fisheries. specialized OCEAN INDIEN ATLANTIQUE 040 038 [Early access] [12 ] 2022 2398-9629 https://www.documentation.ird.fr/hor/fdi:010084720 10.1038/s41893-022-00883-y 2398-9629 [F B010084720] https://www.documentation.ird.fr/hor/fdi:010084720 https://www.documentation.ird.fr/intranet/publi/2022-06/010084720.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-06-03 2025-02-24 fdi:010084720 fre
