Long term monitoring of Missouri River fish populations remains an important component of pallid sturgeon recovery efforts. We who work at the Columbia Fish and Wildlife Conservation Office monitor the lower 250 miles of the Missouri River as part of the larger basin-wide Pallid Sturgeon Population Assessment Project. We deploy a suite of gears designed to catch pallid sturgeon of all sizes, as well as other species of the fish community. Unusually persistent ice on the Lower Missouri River prevented sampling during much of this past winter - which made for an extra busy spring. By the end of May, we had completed our standard gill net and trotline efforts for the 2014 season.

This year was notable for the relatively high gill net catches of Pallid Sturgeon and the overall strong representation of the 2011 pallid sturgeon hatchery year class. Once again, shovelnose sturgeon was the most common species collected in both gill nets and trotlines, and blue sucker catches appeared to be promising. This year represents the 12th year Columbia FWCO has fully implemented the Pallid Sturgeon Population Assessment Project.
