| Summary: | Data and custom codes from Czorlich, Y., Aykanat, T., Erkinaro, J., Orell, P. & Primmer, C.R. (2021) Rapid evolution in salmon life-history induced by direct and indirect effects of fishing. Science. Codes: The R file "Fishing_effort_parallel.R"was used to estimate fishing effort/intensity (beta in equation 8) given the length distribution, the gear-specific catchabilityand harvest rate "Fishing_selection_estimate.R" wasused to estimate fishery-induced selection at vgll3. Datasets: Genetic_phenotypic_data.xlsx: Genetic and phenotypic data about salmon from the Teno mainstem population sonar_data.xlsx: Number of salmon per length classentering the river in 2018 and 2019. The length classes of salmon caught in those years by one of the fishing methods are also included annual_catch_data.xlsx: Total mass (kg) of salmon caught by each fishing method between 1975 to 2014. Environmental_data.xlsx: Data about Barents Sea temperature, biomass of key species, fishing data individual_weight_salmon_catches.xlsx: Individual weight of salmon caught with different fishing gears in the last decades Data sources: - Genetic data (Tenojoki population, random sampling): From Czorlich et al. 2018,https://datadryad.org/stash/dataset/doi:10.5061/dryad.7hm4708 -Data about krill biomass (1980 – 2013) were taken from ( 1 , 2 ). - Capelin biomass estimated from acoustic survey and the landed capelin catches were derived from ( 3 ) for 1973 – 2013. - Herring biomass data were retrieved from ( 4 ) for the 1973-1998 period. Herring biomass was calculated from the number of 1-2 year old herring and the mean weight per age as reported in ( 3 ) for 1988 – 2013. - The annual biomass of cod (a predator of forage fish) was derived from VPA analyses (( 5 ), table 3.24). Landed cod biomass was also taken from ( 5 ). - An index for mesozooplankton (a forage fish food source) corresponding to the sum of Calanus biomass indices from different parts of the Barents Sea was used ( 6 ). - The annual sea temperature in the Kola section of the Barents ...
