These datasets were manipulated and produced in aggregated maps by showing the intensity of VMS (and not the effort) by a methodology used in the Department of Fisheries and Aquaculture. Since most of the vessels are under 12 m and have no VMS, these maps represents only a fraction of the Drifting Long Lines vessels - 59.1% of the vessels targeting Tuna.For this dataset of tuna 2-3 knots for hauling and speed were taken into consideration. This data was funded by of one of the co-financed EU LIFE+ Funding Programmes - LIFE BaĦAR for N2K project.
