Lake Superior South Lake Sturgeon
Lake Sturgeon Movement Along Lake Superior's South Shore
April 2016 - October 2028
Lake sturgeon (Acipenser fulvescens) rehabilitation in Lake Superior has become a priority over the last 20 years, building off recommendations from A Lake Sturgeon Rehabilitation Plan for Lake Superior. Effective rehabilitation and management is dependant on a basic understanding of movement and dispersal patterns of all life stages. However, attempts to track movement through tag recaptures and returns has provided insufficient data. Up to 200 lake sturgeon will be acoustically tagged during spawning runs and index surveys in 2016-2018. Movement will be detected by acoustic receiver arrays deployed along the shoreline and in spawning tributary mouths.
