This report provides a synthesis of results obtained between 2005 and 2008 from the Comprehensive Sturgeon Research Program, an interagency collaboration between the U.S. Geological Survey, Nebraska Game and Parks Commission, U.S. Fish and Wildlife Service, and the U.S. Army Corps of Engineers’ Missouri River Recovery―Integrated Science Program. The goal of the Comprehensive Sturgeon Research Program is to improve fundamental understanding of reproductive ecology of the pallid sturgeon with the intent that improved understanding will inform river and species management decisions. Specific objectives include:

• Determining movement, habitat-use, and reproductive behavior of pallid sturgeon;

• Understanding reproductive physiology of pallid sturgeon and relations to environmental conditions;

• Determining origin, transport, and fate of drifting pallid sturgeon larvae, and evaluating bottlenecks for recruitment of early life stages;

• Quantifying availability and dynamics of aquatic habitats needed by pallid sturgeon for all life stages; and

• Managing databases, integrating understanding, and publishing relevant information into the public domain.
