| Species | Development state | Trait | Primary Data | Secondary Data |
| Sander vitreus | Egg | Oocyte diameter | The mean diameter of ripe walleyes was 1.72 (range 1.40-2.04), earlier description was 2.12 [Not specified] | 1.72 mm |
| Sander vitreus | Female | Age at sexual maturity | Not females mature before age III and all matured by age V. Females from the eastern basin were about 50 and 92% mature at ages III and IV, respectively. Females from the western basin were about 85% mature at age III and almost 99% mature at age IV. Females from Lake Erie matured primarily at ages IV and possibly at V and few fish were mature at age II | 3.0 year |
| Sander vitreus | Female | Length at sexual maturity | The total length of the smallest mature female from the eastern basin was 433 mm; about 50% were mature at 450 mm and all were mature at 540 mm. The smallest mature female from the western basin was 378 mm long; 50% were mature at 430 mm and all were mature at 510 mm | 433.0 cm |
| Sander vitreus | Female | Absolute fecundity | 48-614 | 331.0 thousand eggs |
| Sander vitreus | Male | Age at sexual maturity | All age-II males were mature in the eastern basin but only 96% of those in the western basin were mature | 96.0 years |
