Shellfish production in kilograms in 2010-2015 in geometry form: area (polygon). Swedish data covers only the permitted production in year 2015 (Swedish data in the point dataset). The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Denmark (area), Germany (points) and Sweden (points). The activity was declared as not relevant in Estonia, Finland, Latvia, Lithuania, Poland and Russia. Attribute specification and units ID: Mariculture identification (DK) NR: Identification number (DK, mariculture permits) Country: Country AVG_all: A calculated average of production in 2010-2015 (Kg/year) AVG_11_15: A calculated average of shellfish production in 2011-2015 (Kg/year) 2010_Kg – 2015_Kg: An annual shellfish production (Kg) Area: Area of the shellfish mariculture (km2)

The dataset contains the location of shellfish mariculture sites from EMODnet (https://www.emodnet-humanactivities.eu/search-results.php?dataname=Shellfish+Production). Data from HOLAS 2 was used to complement the dataset (https://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/21efdecc-2fd7-4bfb-9832-68c995291bf7). Each point has the following attributes (where available): status (active, inactive, licensed) country owner name area name farm type (Mussels, Oysters, Mussels-Oysters, Clams, Specialised (other), Mixed (other)) production method (Beds, Long lines, Rafts, Saltwater closed (recirculation), Saltwater ponds, Saltwater tanks/raceways,Trestles or trays, Other) production stage (Grow out for human consumption, Hatchery, Nursery, Broodstock, Reproduction, Harvest, Other) purpose (Commercial, Research, Education, Display, Other) products detailed (English translation of the information provided on species grown or authorised in the source) point information (Polygon centroid, Original) depending on how the information is provided in the source (polygons or points) site_id distance to coast (meters) position from coastline (At sea, within the coastline) notes: indication of HOLAS 2 data
