Comprehensive Sturgeon Research Project (CSRP)

Science Center Objects

The Comprehensive Sturgeon Research Project (CSRP) is a multidisciplinary project conducted in cooperation with the U.S. Army Corps of Engineers, Missouri River Recovery Program–Integrated Science Program.  CERC scientists are working with river scientists and man­agers to develop methods, baseline information, and research approaches that are critical contributions to recovery success of the pallid sturgeon.

CERC research examines the linkages among flow regime, re-engineered chan­nel morphology, and reproductive success and survival of pallid sturgeon within the Missouri River Basin. Specific research objectives include the following:

 

Pallid sturgeon free embryo at approximately 2 days post-hatch

Pallid sturgeon free embryo at approximately 2 days post-hatch, approximately 11-12 mm (about 0.45 of an inch) in length.

Pallid Sturgeon Early Life

Principal Investigators – Aaron DeLonay, Kim Chojnacki 

CERC biologists focus on improving understanding of biomechanics of eggs, free embryos, and larvae through direct observation and measurement. An improved understanding of biomechanics – how biotic conditions and processes interact with physical processes to result in changes in survival – is necessary to create quantitative links between management actions and population-level results.

Adult Pallid Sturgeon Reproductive Ecology

Principal Investigators - Pat Braaten, Ph.D., Aaron DeLonayCaroline Elliott, and Kim Chojnacki

CERC fish biologists study migrations, reproductive cues, and spawning behaviors of reproductive wild and hatchery-origin pallid sturgeon (HOPS) in the Missouri River Basin.

Pallid Sturgeon Habitat Dynamics 

Principal Investigators Robert Jacobson, Ph.D., Susannah O Erwin, Ph.D.Caroline Elliott, and Ed Bulliner

CERC scientists apply advanced measurement and modeling approaches to quantifying habitats in large rivers. Our research has been applied to improving the understanding of the reproductive ecology of the endangered pallid sturgeon (Scaphirhynchus albus) in the Missouri River.

Missouri River Recovery Implementation Committee (MRRIC) and Adaptive Management 

Principal Investigators Robert Jacobson, Ph.D.

This project centers on assimilation of data, interpretation of results, updating quantitative models, and providing policy-neutral, high-quality information to the agencies and stakeholders in the Missouri River Basin.
