Vessels are listed according to an ascending order of vessel length overall (LOA). Daily (dFC) and annual fuel consumption (yFC), annual GHG emission (yGHG), annual landings, fuel use intensity (FUI, litres of fuel per ton of landed fish) and carbon footprint (CF, kg of CO2-eq per ton of landed fish) are reported for common sole fishery (Northern Adriatic) and fishery targeting both common sole and purple dye murex species (Central Adriatic). The data source can be either the current on-site investigation (AUDIT) or the logbooks and landing declarations (DCF). See Table 3 for specifications of the parameters and metrics. Regardless target species, landings refer to the overall catch (e.g., all landed species). Vessel length segment (VL) is assigned based on LOA (VL0612: vessel between 6 and 12 m; VL1218: vessel between 12 and 18 m; VL1824: vessel between 18 and 24 m; VL2440: vessel between 24 and 40 m). See Supplementary Information for details on the landings by main species.
