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