Species | Development state | Trait | Primary Data | Secondary Data |
Sander vitreus | Egg | Egg adhesiveness | Soon after fertilization the eggs were treated with a weak tannic acid solution to reduce adhesion and rinsed twice. Water was then added gradually and eggs were stirred with a feather occasionally to further reduce adhesion | Non-Adhesive |
Sander vitreus | Egg | Temperature for incubation | Incubated in seperate chambers at 12°C | 12.0 °C |
Sander vitreus | Spawning conditions | Spawning season | Ripe ova were collected from individual females on 5 May and 6 May | ['May'] |
Sander vitreus | Female | Length at sexual maturity | Fork length, population of Manitoba 625 +/-15, and Ontario 663 +/-12 | 625.0 cm |
Sander vitreus | Larvae | Initial larval size | 8.53 +/- 0.05 mm at hatching | 8.53 mm |
Sander vitreus | Female | Age at sexual maturity | Females ranged in age from 5 to 18 years, and from 6 to 18 years in the Lake Manitoba and Lake Ontario trials. For both populations, this age range covered the majority of spawning females seen in recent spawning runs | 5.0 year |
