"Evaluation of lake sturgeon (Acipenser fulvescens) populations in the St. Clair River and Lake St. Clair, Michigan"
Supported by a Federal Aid in Sport Fish Restoration Grant
Annual trawl assessment for lake sturgeon on Lake St. Clair, Michigan
Co-principle Investigators: Michael Thomas and Robert Haas, Michigan DNR
(1) determine spawning period, area distribution of spawning activity, and characterize spawning habitat in the St. Clair River; (2) determine early (juvenile) life history of lake sturgeon in the St. Clair River and Lake St. Clair and identify habitat requirements of young lake sturgeon; (3) document lake sturgeon population parameters for Lake St. Clair and the St. Clair River, including estimated abundance, exploitation, age composition, growth rate, and age/sex composition of the spawning stock.
The study is a cooperative effort between MDNR, USFWS Alpena FRO (Jerry McClain), and USGS-BRD Great Lakes Science Center (Tom Edsall). USFWS staff at the Alpena FRO coordinate tag return data collection with other fisheries research agencies and commercial fishing operations in Lakes Huron and Erie. USGS staff characterize spawning habitat using remote underwater video, side-scan sonar, and acoustic doppler current profiler.
