This core indicator evaluates the abundance of typical species of fish, such as perch and flounder, in the coastal areas of the Baltic Sea, to assess environmental status. Quantitative thresholds are used to evaluate core indicators status in "Achieve", "Fail" or "Not assessed". As a rule, good status is achieved when the abundance is above a set site- and species-specific threshold value. This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas). Attribute information: "HELCOM_ID" = ID of the HELCOM scale 3 assessment unit "Country" = Country/ Opensea "level_2" = Name of scale 2 HELCOM assessment unit "level_3" = Name of scale 3 HELCOM assessment unit "Area (km2)" = Area of the HELCOM scale 3 assessment unit "Coastal" = Code of scale 3 HELCOM assessment unit "Open sea" = Name of the open sea area "Coast_Code" = Code of scale 3 HELCOM assessment unit "Indicator" = indicator and species name "Unit" = Unit of the indicator "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "AULEVEL" = Assessment unit level used for the indicator "Type" = 1 = boundary values increase/decrease monotonically, 2 = optimum range indicator "Threshold" = Threshold value of indicator "Indicator value" = Result for the indicator "ConfA" = Confidence of classification "ConfT" = Temporal confidence of classification "ConfS" = Spatial confidence of classification "ConfM" = Methodological confidence of classification

This core indicator evaluates the status of coastal sea areas of the Baltic Sea based on the abundance of sea trout parr in rivers where they breed. The determination of whether good status is reached is based on a comparison of the observed parr densities in rearing habitats with the reference potential parr densities in the specified habitats. This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas). Attribute information: "HELCOM_ID" = ID of the HELCOM scale 3 assessment unit "level_2" = Name of the HELCOM scale 2 assessment unit "level_3" = Name of HELCOM scale 3 assessment unit "ICES Subdivision" = ICES assessment unit number "Area (km2)" = Area of the HELCOM scale 3 assessment unit "Indicator_" = Name of the indicator "Unit" = Unit of the indicator "Type" = 1 = boundary values increase/decrease monotonically, 2 = optimum range indicator "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "ConfA" = Confidence of classification "ConfT" = Temporal confidence of classification "ConfS" = Spatial confidence of classification "ConfM" = Methodological confidence of classification "notes" = additional info "AULEVEL" = Assessment unit level used for the indicator

HELCOM Coastal fish core indicator database (COOL) contains updated data used in coastal fish core indicators for every current monitoring station in the Baltic Sea and information on the latest status assessment for the two coastal fish indicators: http://www.helcom.fi/baltic-sea-trends/indicators/abundance-of-coastal-fish-key-functional-groups/ http://www.helcom.fi/baltic-sea-trends/indicators/abundance-of-key-coastal-fish-species The collection of monitoring data is described in the Monitoring guideline: http://www.helcom.fi/Documents/Action%20areas/Monitoring%20and%20assessment/Manuals%20and%20Guidelines/Guidelines%20for%20Coastal%20fish%20Monitoring%20of%20HELCOM.pdf The database was developed in BalticBoost project (http://www.helcom.fi/helcom-at-work/projects/completed-projects/baltic-boost/) Theme 1: Biodiversity, which focused on developing a biodiversity assessment tool and improving data arrangements for the biodiversity elements where this is limited (e.g. coastal fish, birds and seals) so that a comprehensive assessment of biodiversity in the Baltic Sea can be carried out by 2018. The monitoring data is reported by HELCOM Contracting Parties and reported data is verified annually by HELCOM FISH-PRO group.

This indicator evaluates the status of the Baltic Sea area based on salmon smolt production in rivers flowing into the sea, also making use of additional supporting data on numbers of adult spawners. Determination of whether the threshold value that determines good status is achieved is based on a comparison of estimated smolt production with an estimated potential smolt production capacity. This dataset displays the result of the indicator in HELCOM Assessment Scale 2 (Division of the Baltic Sea into 17 sub-basins). Attribute information: “SB_Code” = Code of the Helcom subbasin "Name" = Name of the Helcom scale 2 assessment unit "AREAKM2" = Area of the Helcom scale 2 assessment unit HELCOM_ID = Helcom id of the Helcom scale 2 assessment unit ICES_AU = ICES assessment unit number Threshold = Threshold Threshold_v = Threshold value for this indicator "Ind_value" = Value for the indicator in Helcom scale 2 assessment unit Status = Status of the indicator (“Good”, “Not good” or “Not assessed”) comment = additional info

The data set is showing nursery areas for fish in the shallow waters of the Baltic Sea area as polygons used for the BRISK project (Sub-regional risk of spill of oil and hazardous substances in the Baltic Sea, http://www.brisk.helcom.fi/). This dataset has been produced by COWI (http://www.cowi.dk) based on data collected from Poland and Russia and by COWI from polygons created from 10 m depth curve. The dataset includes data provided by the BRISK Project Partner organisations. The detailed documentation of what partner provided what data is given in the Annex of the document: 70618-3.1.2.2 Data Collection Report. Shallow water areas are nursery areas for a long list of fish. Particularly during summer these areas are vulnerable.
