Description

Aquaculture sites where shellfish production occurs in tanks or cages.

MSP Challenge

Shellfish production sites are editable and add to the following pressures in the ecosystem:

• Surface disturbance
• Artificial substrate

Description

Abstract as in EMODnet (retrieved on 2022-05-23):

"The database on shellfish aquaculture in the EU was created in 2014 by AND-International for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by national sources across the EU (plus Norway and the UK) and by the project Euroshell." (...) "The database contains points representing shellfish farms or shellfish production areas (depending on available data) in the following countries: Bulgaria, Denmark, France, Greece, Ireland, Italy, Netherlands, Norway, Slovenia, Spain and United Kingdom. Data from Bulgaria, Denmark, Greece, Ireland, Norway, Spain and Scotland come from the official lists of registered aquaculture sites. Data from France relies on cadastral data. Data from the Netherlands, Italy and England and Wales come from the Euroshell project. Data is missing for Germany, Portugal, Sweden and Croatia. Except for Germany, the shellfish production remains limited in those MS. There is no production in other MS. Each point has the following attributes (where available): status (active, inactive, licensed), country, owner 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 (metres), position from coastline (At sea, within the coastline). The farm type relies on a typology established by AND-International, based on available information on species grown or authorised. A relational table provides harmonised information about species grown or authorised using Eurostat nomenclature for the Species Group (Mussels; Oysters; Clams, cockles, arkshells; Scallops, pectens; Abalones, winkles, conchs; Sea-urchins and other echinoderms) and when available the species name (e.g. Blue mussels - Mytilus edulis). The distance to coast (EEA coastline shapefile) has been calculated using the original data map projections, where available. In the other cases it was used the UTM WGS84 Zone projected coordinate system where data fall in. Compared with the previous version this new version includes updated data for Denmark, Greece, Ireland, Norway and Scotland and new data from Slovenia and Spain."

Methodology

Selected features in the North Sea region, within 10km from the coast and within 2km from a river. The layer was styled according to the Farm Type attribute and the farm types "mixed (other)", "specialised (other)" and "n.a." where merged into a type called "other".

Shellfish mariculture points

Description

"Shellfish production in kilograms in 2010-2015 in geometry form: points. Swedish data covers only the permitted production in year 2015.

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."
