Clupeids and stickleback biomass, fishery landings, and hydrographic variables from the Baltic Sea

• Insamlingsmetod: Kompilering/Syntes
• Beskrivning av insamlingsmetod:
  The data on fish biomasses were collected via hydroacustic surveys, coupled with information on species and size distributions from trawl hauls.
  Commercial landings of herring and sprat expressed as tons per ICES rectangle were provided by the Scientific, Technical and Economic Committee for Fisheries (STECF, https://stecf.jrc.ec.europa.eu/dd/effort/graphs-quarter) for the years 2003–2015, and by the Joint Research Centre (JRC, https://jeodpp.jrc.ec.europa.eu/ftp/jrc-opendata/FAD/fdi2020/) for the years 2016–2019.
  Data on water temperature, salinity and nutrient concentrations for the period 2001–2019 for each ICES rectangle were extracted from Copernicus Marine Service Information. The nutrient concentration data were produced using the biogeochemical model ERGOM one-way online-coupled with the ice-ocean model system NEMO (doi.org/10.48670/moi-00012). The salinity and temperature data were produced by DMI (Danmarks Meteorologiske Institut) using NEMO (doi.org/10.48670/moi-00013).
  
  All analyses were conducted in R Statistical Software version 4.2.0 (R Development Core Team 2020). We used the mgcv package (version 1.8-40) for specifying, fitting, and visualising the GAMs (Wood 2011), and the nlme package (version 3.1-162) for fitting generalized least square models (Pinhero et al. 2016).
