Physical characteristics of pallid sturgeon and shovelnose sturgeon eggs

This dataset describes the diameter, 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 fertiliza...

Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River, 2009-2015-Data

The data was collected at two lower Mississippi River sites and consists of year round pallid sturgeon Scaphirhynchus albus capture attributes (including habitat type at capture location) from 116 telemetry-tagged fish and habitat area estimation for the sites.

Pallid Sturgeon Spawning Habitat in the Lower Missouri River

Lack of reproduction has been hypothesized to be a factor in the decline of the pallid sturgeon (Scaphirhynchus albus) through much of its range. Spawning habitat and behavior have only recently been documented on the Lower Missouri River, which comprises over 1,300 river kilometers of undammed river. This data consists of present habitat measurements for ten pallid sturgeon spawning even

Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon, USA, 2007-2009

Mercury flux and fate (whether mercury was retained in the aquatic ecosystem or exported to the riparian ecosystem via blackfly emergence) was calculated based on animal consumption rates and total mercury concentration of diet items. Consumers and their gut contents were collected at six sites on the Colorado River in the Grand Canyon. Sites ranged from 0-367 river kilometers downstream of L...

Semi-automated and manual enumeration of bigheaded carps from recreational-grade side-scan sonar imagery, Perche Creek, MO, 2018

The dataset consists of count data derived from a series of sonar images. The data are fish counts per image from 1) a computerized process to extract fish counts, and 2) three manual assessors. Each image has a total of four associated fish counts.

Segment-scale classification, large rivers of the Upper Midwest United States

This dataset is part of a multi-scale assessment and classification for segments of 15 rivers of the Upper Midwest United States that meet various criteria for largeness. All rivers are tributary to the Mississippi River system. The 11,600 kilometers (km) that qualified as large were parsed into 10-kilometer-long segments and classified by major alterations (free-flowing, navigation poo
