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

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
Beskrivning av data och filstruktur: data om fiskbiomassa, fiskelandningar och hydrografiska variabler från Östersjön. Datan användes för att undersöka sambanden mellan sillfiskar och storspigg, särskilt om minskad predation från sill och konkurrens från både skarpsill och sill kan ha bidragit till den senaste tidens ökning av storspigg i Östersjön.
