Abundance of key coastal fish species 2018 HOLAS 2
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

The raw data on which this assessment is based, are stored in national databases. Each country has its own routines for quality assurance of the stored data. From 2017, each country calculates indicator values for their monitoring locations from the raw data from fish monitoring. The indicator data and values are then during the first half of the year uploaded to the HELCOM database for coastal fish core indicators, COOL ( http://bio.helcom.fi/coastalfish) as hosted by the HELCOM secretariat. Indicator data for status assessments are extracted from the COOL database, and the assessment undertaken by the lead country (Sweden) according to the assessment protocol outlined in this report.
This indicator uses two different approaches for evaluating whether good status is achieved. The approach used depends on the data used for the evaluation. If certain criteria are met, then the baseline approach is used. If not, then the trend based approach is used.
