Abundance of coastal fish key functional groups - piscivores 2018
This core indicator evaluates the abundance of selected functional groups of coastal fish in the Baltic Sea. Quantitative thresholds are used to classify core indicators status in "Achieve", "Fail" or "Not assessed". As a rule, good status is achieved when the abundance of piscivores (i.e. fish that feed on other fish) is above a site-specific threshold value, and the abundance of cyprinids or mesopredators (i.e. mid trophic-level fish) is within an acceptable range for the specific site. The status of functional groups of coastal fish in the Baltic Sea has been evaluated by assessing the status of piscivores and cyprinids/mesopredators during the period 2011-2016.
This dataset displays the result of the indicator for piscivores in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas).
Attribute information:

"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
"Subbasin code" = Code of the HELCOM subbasin (scale 3)
"Indicator" = Name of the indicator
"Unit" = Unit of the indicator
"Type" = 1 = boundary values increase/decrease monotonically, 2 = optimum range indicator
"Threshold" = Threshold value of indicator
"Indicator value" = Result value for the indicator
"Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)
"AULEVEL" = Assessment unit level used for the indicator
"ConfA" = Confidence of classification
"ConfT" = Temporal 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 (HELCOM Coastal Fish database) 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.
The level of confidence of the assessment differs across areas and regions as a result of differences in monitoring methodology as well as in some countries poor temporal and spatial coverage of monitoring due to poor financial support for monitoring.
This indicator uses two different approaches for evaluating whether Good Environmental Status is achieved. The approach used depends on the availability of data. If there is sufficient data (at least 15 years’ time series), then the baseline approach is used. If the criteria for applying the baseline approach are not fulfilled, then the trend based approach is used.
