Abundance of salmon spawners and smolt 2018
收藏资源简介:
This indicator evaluates the status of the abundance of salmon spawners and smolt in the Baltic Sea based on salmon smolt production in rivers flowing into the sea, also making use of additional supporting data on numbers of adult spawners. Determination of whether the threshold value that determines good status is achieved is based on a comparison of estimated smolt production with an estimated potential smolt production capacity. This dataset displays the result of the indicator in HELCOM Assessment Scale 2 (Division of the Baltic Sea into 17 sub-basins). Attribute information: "HELCOM_ID" = ID of the HELCOM scale 2 assessment unit "Subbasin code" = Code of the HELCOM subbasin "Name" = Name of the HELCOM scale 2 assessment unit "ICES_AU" = ICES assessment unit number "Threshold" = Threshold for good status (75% of potential smolt production capacity (PSPC)) "Threshold value" = Threshold value for the assessment unit "Indicator value" = Indicator result value 2016 for HELCOM scale 2 assessment unit "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "Comment" = Additional info "Area (km2)" = Area of the HELCOM scale 2 assessment unit "AULEVEL" = Assessment unit level used for the indicator "indicato_1" = Indicator result value 2011-2016 "ConfA" = Confidence of classification "ConfT" = Temporal confidence of classification "ConfS" = Spatial confidence of classification "ConfM" = Methodological confidence of classification
