Abundance of key coastal fish species 2018 HOLAS 2
Description
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
