Wisconsin Department of Natural Resources Lake Sturgeon Movement within the Black River, WI (WIDNRBRF)

Over the past decade there has been a noticeable increase in lake sturgeon activity within the Lower Black River and it seems that the population has been steadily increasing. Wisconsin DNR Black River Falls Fish Management Crew is interested in the life history, movement and population characteristics of the Black River lake sturgeon and began acoustically tagging and tracking lake sturgeon in 2022. To date we have acoustically tagged 20 lake sturgeon (10-year tag life). Initial results are showing seasonal use and movement between the Black River and Mississippi River by some fish while others choose to reside solely in the Black River.
