The spatial extent of Walleye and Lake Sturgeon spawning migrations below a dam in the lower Black Sturgeon River, Lake Superior

Ecology of Freshwater Fish, Volume 33, Issue 4, October 2024.
Abstract In the Laurentian Great Lakes, the issue of barrier removal is complicated by the presence of non‐native species below barriers. A fish tracking study was conducted to guide efforts for barrier remediation decisions for the restoration of fish populations with a focus on Walleye (Scander vitreus) and Lake Sturgeon (Acipenser fulvescens) in the
