Cross-analysis of fuel data with the scientific Fisheries Dependent Information (FDI) dataset

The theoretical LOA-based fuel use model was applied to the Scientific Fisheries Dependent Information (FDI) effort dataset to infer specific fuel consumption per fishing day (including steaming and towing) for each fishery and vessel segment. National FDI landings were matched to the effort data, hence fuel consumption, to allow the computation of FUI and CF at the entire fleet and vessel segments level. Annual fishing fleet effort and landing 2019 data of the entire national trawl fleet were obtained from the FDI database, made freely available in aggregated form for ease of access by the Joint Research Centre (JRC) data dissemination tool, with detailed landings by gear, species and area of capture. The FDI database is updated annually and published at https://stecf.jrc.ec.europa.eu/dd/fdi together information on the data-handling procedures. The JRC data dissemination tool provides access to data submitted by EU Member States to the European Commission under the provisions of the Data Collection Framework (DCF). Fishery data are collected by EU Member States on the basis of national sampling programmes.
