Data for Furcellaria harvesting presenting the amount of dredged tonnes per unit area per year. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia. The activity was declared as not relevant in Denmark, Germany, Finland, Latvia, Lithuania, Poland, Russia and Sweden. Attribute specification and units: Dredged_ar: Furcellaria dredging area (km2, ND = no data available) Area: Area (fishing area) within dredging occurs (km2), area do not represent actual dredging area. 2011 - 2015: Amount of dredged Furcellaria (tonnes / year) Total: Amount (Sum) of dredged Furcellaria during 2011-2015 (tonnes) Average: Calculated annual average of the amount of dredged Furcellaria (tonnes/year)

Furcellaria areas of production remained the same since the HELCOM Second Holistic Assessment of the Ecosystem health of the Baltic Sea (HOLAS 2). The production figures were extracted from EUROSTAT. Data contain data for the period 2016-2020 for Estonia. Attribute specification and units: Dredged_ar: Furcellaria dredging area (km2, ND = no data available) Total: Amount (Sum) of dredged Furcellaria during the period (tonnes) Average: Calculated annual average of the amount of dredged Furcellaria (tonnes/year) Area_km2: Area (fishing area) within dredging occurs (km2), area do not represent actual dredging area. F2016 - F2020: Amount of dredged Furcellaria (tonnes / year)
