Shovelnose sturgeon from the Marias River, MT

Our goal is to determine the fate and behavior of larval pallid sturgeon and shovelnose sturgeon in a reservoir headwater. The results from this study will address the contemporary theory that sturgeon larvae drift in to reservoirs and succumb to mortality, thus the lack of sturgeon recruitment is a function of drift distance and reservoir headwater environments.
