Abundance of coastal fish key functional groups - cyprinids results HOLAS 3
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 2016-2021.
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:

"coast" = Code of scale 3 HELCOM assessment unit
"open_sea" = Name of Open sea HELCOM assessment unit
"SAUID" =
"SAUlevel" =
"Indicator" = Name of the indicator
"ECID" = Ecosystem component ID
"EClevel" = Ecosystem component level
"EcosystemC" = Ecosystem Component
"EQR" = Ecological Quality Ratios
"Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)
