Physical characteristics of pallid sturgeon and shovelnose sturgeon eggs
April 7, 2020
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.

Physical characteristics and simulated transport of pallid sturgeon and shovelnose sturgeon eggs
The imperiled pallid sturgeon (Scaphirhynchus albus) and closely related, but more common, shovelnose sturgeon (S. platorynchus) are believed to broadcast adhesive, demersal eggs in the current and over coarse substrate in turbid rivers of the North American midcontinent. It has been hypothesized that eggs settle immediately following fertilization, but field conditions preclude direct...
