Abundance of coastal fish key functional groups - cyprinids mesopredators 2018 (HOLAS 2)
Description
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 cyprinids/ mesopredators 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
"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 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
"ConfS" = Spatial confidence of classification
"ConfM" = Methodological confidence of classification
