This dataset describes the diameter, shape, settling velocity, and specific gravity of eggs from 9 female pallid sturgeon and 14 female shovelnose sturgeon as determined in laboratory studies. Pallid sturgeon and shovelnose sturgeon are believed to broadcast demersal eggs in the current, near the river bed over coarse substrate. It is hypothesized that eggs settle immediately following fertilization, but field conditions preclude direct observation. The dispersal of sturgeon eggs is affected by physical properties of the eggs and hydraulic conditions at the spawning location.
