Pallid Sturgeon Population Assessment and Associated Fish Community Monitoring for the Missouri River: Segment 13

Pallid Sturgeon (Scaphirhynchus albus) have declined throughout the Missouri River since dam construction and inception of the Bank Stabilization and Navigation Project in 1912 (Carlson et al. 1985). Loss of habitat, reduced turbidity, increased velocity, loss of natural flows, reduction in forage, hybridization and inadequate reproduction and recruitment are factors contributing to the decline of the Pallid Sturgeon and other native species (Pflieger and Grace 1987). Surveys conducted throughout the Missouri and Mississippi rivers have found evidence of hybridization between Pallid and Shovelnose Sturgeon and a continued decline of wild Pallid Sturgeon relative abundance (Schrey et al. 2011, Grady et al. 2001, Doyle and Starostka 2003, Doyle and Starostka 2004).
