Symposium Summary: Understanding Pallid Sturgeon Population Dynamics and Stressors in the Missouri and Mississippi Rivers

15-pallid-sturgeon-hatchery-pallid1-usacePallid Sturgeon Scaphirhynchus albus occupy some 4,500 miles of Missouri and Mississippi rivers and Kansas City was a fitting location to host a symposium for this endangered fish, as the Missouri River flows just minutes from the conference site. This full-day session featured over 20 speakers representing a wide range of state and federal agencies and universities. The purpose of this symposium was to promote collaboration among a multitude of entities that are currently working towards Pallid Sturgeon recovery throughout the central United States. This session provided a forum to discuss hypotheses and management actions related to Pallid Sturgeon recovery and other information that could be used to improve the effectiveness of restorative efforts. A variety of presentations were given on research on Pallid Sturgeon, as well as the closely-related Shovelnose Sturgeon Scaphirhynchus platorynchus, ranging from early-life history to adult stages. Topics included larval drift dynamics, habitat use, prey consumption and condition, genetics and hybridization, population modeling, spawning habitat and behavior, and post-stocking monitoring of hatchery-reared individuals, just to name a few. The U.S. Army Corps of Engineers was pleased to organize this event and we thank all of the presenters for their time and expertise. Read the abstracts here.
