Columbia NFWCO Begins Winter Gill Netting for Pallid Sturgeon Population Assessment.
Midwest Region, November 1, 2007

On November 5th, a gill netting crew from Columbia National Fish and Wildlife Conservation Office (NFWCO) bravely embarked on a mission to catch the elusive pallid sturgeon.  Working around holidays, fog, rain, snow, and freezing cold, the crew managed to sample nine bends of the Missouri River resulting in the capture of seven pallid sturgeon.  Five volunteers from the University of Missouri have assisted in the sampling and proved to be good luck.  Two pallid sturgeon have already been taken to Neosho National Fish Hatchery for propagation efforts. 


This sampling is part of a basin wide effort to monitor the pallid sturgeon population in the Missouri River.  Crews from other agencies along the entire river will be sampling until early spring or until ice flows shut them down.  We have experienced a drop in water temperature from 12.8 °C to 7.0 °C in the month of November and fully expect to see ice flowing sometime soon.


Monitoring fish populations accomplishes the Service’s native species conservation and management goal.  The pallid sturgeon monitoring program also provides useful data on the other species in the Missouri River.
