Physical characteristics of pallid sturgeon and shovelnose sturgeon eggs 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.

Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

In the field study, we measured number of eggs collected on mats and with bottom drift nets in the Detroit River to compare capture effectiveness. The field collection data describe the number, date of collection, and exact collection location of target species (walleye and lake whitefish). The flume trial data include number of eggs retained or collected, water velocity,...

However, little is known about the collection techniques efficacy and bias when collecting fish eggs. We conducted a literature review to assess egg collection methods and evaluate egg retention and capture on egg mats. The literature review provided a summary of different gear types used to collect fish eggs, possible bias from the gears, and egg 'abundance' reporting strategies.
