Abstract

The U.S. Geological Survey (USGS) in partnership with the Nebraska Game and Parks Commission (NGPC) and the U.S. Army Corps of Engineers have confirmed spawning of two female pallid sturgeon in the upstream reaches of the lower Missouri River in May 2007. Combined with supporting research in reproductive physiology, identification of spawning habitat, and early life history this result provides new understanding of environmental factors (for example, photoperiod, temperature, water quality, and flow regime) that might affect reproduction of this endangered species. The purpose of this fact sheet is to provide stakeholders, scientists, and managers with some of the preliminary results from the 2007 field assessment of sturgeon reproduction in the lower Missouri River.
