Abstract: Sediment resuspension is among the most widely cited concerns that lead to restricted dredging timeframes. Protection of fish species is a primary concern regarding the effects of dredging operations, yet experimental data establishing thresholds for uncontaminated suspended sediment effects are largely lacking. We conducted research to determine suspended sediment effects on walleye (Sander vitreus) egg hatching success and gross morphology following exposures mimicking sediment resuspension during dredging operations.
