Abstract
Harvest in walleye Sander vitreus fisheries is size-selective and could influence phenotypic traits of spawners; however, contributions of individual spawners to recruitment are unknown. We used parentage analyses using single-nucleotide polymorphisms to test whether parental traits were related to the probability of offspring survival in Escanaba Lake, Wisconsin. From 2017-2020, 1339 adults and 1138 juveniles were genotyped, and 66% of the offspring were assigned to at least one parent. Logistic regression indicated the probability of reproductive success (survival of age-0 to first fall) was positively (but weakly) related to total length and growth rate in females, but not age. No traits analyzed were related to reproductive success for males. Our analysis identified the model with the predictors growth rate and year for females and the models with year and age and year for males as the most likely models to explain variation in reproductive success. Our findings indicate that interannual variation (i.e., environmental conditions) likely plays a key role in determining the probability of reproductive success in this population and provide limited support that female age, length, and growth rate influence recruitment.

Data includes genotypes of adult and juvenile walleye used in this study, and phenotypic information for the adults and juveniles.
Description of the data and file structure
In the file "phenotype_data.csv", the following variables are:
- gen_id: individual identification numbers for this project
- year: calendar year the individual was captured
- size class: either adult or juvenile, see manuscript for descriptions
- sex: male or female
- length: total length in mm
- weight: total weight at time of capture in grams
- age: age in years at time of capture.
Cells with NA indicate that the fish was not aged.
The file "escanaba_walleye_genotypes.gen" contains the genetic data in "Genepop" format. The sample identifier (matches "gen_id" in the phenotypic data) is in the first column upon loading in R.
