Visual and genetic stock identification of a test fishery to forecast Columbia River spring chinook salmon stocks 2 weeks into the future

# Visual and genetic stock identification of a test fishery to forecast Columbia River spring Chinook salmon stocks 2 weeks into the future This is a data file containing the individual metadata and genotypic data required to analyze the test fishery mixtures from 2017 - 2022 and the mixture data from the Adult Fish Facility at Bonneville Dam for the same time series. The genotypic data were used to perform parentage and genetic stock identification analyses, and the metadata are needed to recreate the weekly strata used in the abundance estimation. ## Description of the data and file structure This is an excel file containing three tabs: "BONAFF_IndData", "TestFishery_IndData", and "Chinook sorted_genotypes". The "BONAFF_IndData" is the individual metadata for Chinook salmon collected at Bonneville Dam. The 18 field headings include "Order" (unique number to sort the individuals to correspond with the genotypes), "Rear" (H, HNC, W corresponds with clipped and unclipped hatchery fish and natural-origin as described in methods), Fork length in mm, Adult size categories based on fork length as defined in methods, statistical "Week", hatchery broodstock "GenParentHatchery" assigned by PBT, broodyear "BY", expected GSI reporting group "GenStock_exp", observed GSI reporting group "GenStock_obs", Genetic sex from sex marker genotype, AdClip = AD for adipose clipped and AI for adipose-intact, Physical Tag "PhysTag" indicates other visual marks aside from adipose clips, Management "Period", "Method" contains categories GSI, PBT, failed, or duplicate to indicate whether a fish was successfully genotyped (either GSI assigned or PBT assigned) or failed to genotype for >90% of all loci and whether it represents a unique genotype, and finally "WeekNumber" is the category of week within management period to stratify the sample. The "TestFishery_IndData" tab has similar field headings as the Bonneville sample but also includes "Visual Stock" (Lower or Upriver). Weeknumber in the Test Fishery data codes AD and AI fish and Lower and Upriver VSI fish into different categories of statistical weeks for stratifying the sample. "NA" indicates the data are not applicable and were used in cases when a sample failed to genotype (shown in "Method) which excludes the individual from analysis, or in cases where an individual was unassigned with PBT and the information that would normally be available with a hatchery fish is not available (e.g., broodyear "BY"). The "Chinook sorted_genotypes" has individual genotypes for 343 genetic markers (bi-allelic SNPs) in rows of data corresponding to each unique individual listed in the metadata tabs. "Order" and "CollectionName" and "Individual Name" are the same as those listed in the metadata tabs. Each SNP locus has two alleles listed as "-A1" and "-A2" suffixes. These data can be analyzed using the methods in the publication.
