Clupeids and stickleback biomass, fishery landings, and hydrographic variables from the Baltic Sea
https://doi.org/10.5878/ka8r-8e34
Description of the data and file structure: data on fish biomass, fishery landings and hydrographic variables from the Baltic Sea. The data were used to explore the relationships between clupeids and three-spined stickleback, specifically whether reduced predation from herring and competition from both sprat and herring may have contributed to the recent increase of three-spined stickleback in the Baltic Sea.
The data is structured in six separate datasets. Each record report values of fish biomass or abiotic variables related to a specific ICES statistical rectangle (ca. 55 × 55 km size, corresponding to 0.5 degrees in latitude × 1 degree in longitude) and a specific year. The datasets can be merged using the field "year" and "ICES". The files have the following dimensions: ICES_Hydrographic_data_by_year.csv, 4465 rows × 20 columns; herring_biomass.csv, 2056 rows × 5 columns; landings_herring.csv, 2867 rows × 3 columns; landings_sprat.csv, 2108 rows × 3 columns; sprat_biomass.csv, 2042 rows × 4 columns; stic

Description of the mode of collection:
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).
