Lake Sturgeon (Acipenser Fulvescens) Trophic Position And Movement Patterns In The Lower Niagara River, Ny, Eric Bruestle
Great Lakes Center Masters Theses
Lake sturgeon Acipenser fulvescens were once widely distributed throughout the Laurentian Great Lakes. However, widespread overharvest and habitat degradation has diminished their numbers. The lower Niagara River, NY contains one of the few remaining recovering populations of lake sturgeon in New York State. The goal of this study was to characterize the trophic position of lake sturgeon in the context of an invasive species dominated food web and to describe their movement patterns and residency within the lower Niagara River. Stomach content analysis and stable nitrogen (δ15N) and carbon (δ13C) isotope analysis of tissue was used …
