The dataset on marine finfish aquaculture in the EU was created in 2017 by AND-International for the European Marine Observation and Data Network (EMODnet). The dataset provides information about the location of marine finfish farms in the EU and partner countries where data are available. There is an obligation for EU MS to inventory all authorized aquaculture sites under the Council Directive 2006/88/EC on animal health requirements. Despite this obligation, the availability of data varies among MS from no data available at all to a complete regularly updated dataset. As far as partner countries are concerned, data have been collected only in Norway and the UK (Scotland only), where detailed data are provided online. Data provided here cover Cyprus, Denmark, Estonia, Finland, Greece, Ireland, Malta, Norway, Spain and the United Kingdom (Scotland only). Data collection is still undergoing in other EU MS and neighbouring countries. Each point has the following attributes (where available): Country, Owner name, Status (Active, n.a.), Farm type (Salmonids, Flatfish, Seabass-seabream and other coastal fish, Tuna, Other, n.a.), Production method (Sea cages, Saltwater tanks/raceways, Saltwater ponds, Saltwater closed (recirculation), Quarantine, Other, n.a.), Production stage (Grow out for human consumption, Hatchery, Nursery, Broodstock, Reproduction, Restoration of wild stock, Put and take fisheries, Processing facility, Slaughtering facility, Research facility, Sea ranching, Other, n.a.), Purpose (Commercial, Display, Education, Research, Capture-based aquaculture, Fishing park, Other, n.a.), Species_source (detailed information on species names as presented in the source and translated to English), Point information (Polygon centroid, Original) depending on how the information is provided in the source (polygons or points), Site_ID, the distance to coast (in meters), the position from Coastline (At sea or Within the coastline), the ID from the source to facilitate traceability, and the year the data was updated in the source. The farm type relies on a typology established by AND-International, based on available information on species grown. A relational table provides harmonised information about species grown using Eurostat nomenclature for the Species Group, the species name (commercial and scientific) and the Eurostat code (ALPHA-3 code for species). The data has been updated for all countries available and additional fields were added to improve traceability (ID from source and Year updated in the source). Data from Spain are available for viewing but not for download. Data from other countries are available for viewing and download.
