Although the data mainly contains information on vessels with length above 12m, fishing effort of some parts of the inshore fleet and international vessels are included where data were available. Grid cells in which 3 or less vessels were fishing are suppressed to acknowledge commercial sensitivity of the information.

Report produced for The Crown Estate, OWEC funded project: FiSMaDiM, 11 pages. Doi: `https://doi.org/10.14465/2024.OWEC.003`_ Within the FiSMaDiM (Fisheries Sensitivity Mapping and Displacement Modelling) project, a method was developed to estimate fishing effort information derived from VMS (Vessel Monitoring System) data augmented by AIS (Automatic Identification System) data. Based on information provided by MMO (Marine Management Organisation), MCA (Maritime and Coastguard Agency), fleet register, global fishing watch and marine traffic, AIS (UK and non-UK-flagged vessels) data was added to augment information on fishing effort within the UK EEZ (Exclusive Economic Zone) as derived from VMS (only UK-flagged vessels) data provided by MMO. .. _`https://doi.org/10.1093/icesjms/fsad209`: https://doi.org/10.1093/icesjms/fsad209 .. _`https://doi.org/10.14465/2024.owec.003`: https://doi.org/10.14465/2024.OWEC.003 MEDIN 3.1.1
