The use of remote sensing to detect illegal, unreported, and unregulated (IUU) tuna fishing activities in the Peruvian Exclusive Economic Zone

Supporting information from the manuscript: The use of remote sensing to detect illegal, unreported, and unregulated (IUU) tuna fishing activities in the Peruvian Exclusive Economic Zone (EEZ). The main goal of the study propose the complementary use of AIS and VMS with satellite imagery to detect and characterize IUU activities of foreign fishing vessels targeting the tuna in the Peruvian EEZ. Furthermore, the fishing effort was quantitatively characterized according to full compliance with granted permits, considering three types of IUU activities: fishing beyond the permit timeframe, inside a marine protected area (MPA), or without a valid permit. dataset-1: Operational details for the assessment of the 61 foreign-flagged tuna-targeting vessels evaluated in the Peruvian EEZ during 2022. dataset-2: Quarterly fishing effort detected within the Dorsal de Nasca MPA during 2022, disaggregated by geolocation source. dataset-3: Historical cumulative catches for tuna species in the Eastern Pacific Ocean (EPO), 2011–2022 by species in metric tons. dataset-4: Sanctions imposed by the Peruvian Ministry of Production (PRODUCE) on foreign tuna-targeting vessels for infractions committed between 2011 and 2022.
