"Evaluation of lake sturgeon (Acipenser fulvescens) populations in Northern Michigan"
Supported through a Federal Aid in Sport Fish Restoration Grant
Principle Investigator: Edward A. Baker, Michigan DNR
Cooperator: Nancy A. Auer, Michigan Technological University
(1) Verify presence of spawning and/or larval lake sturgeon in rivers that are suspected of supporting spawning runs; (2) Determine early (larval and juvenile) life history of lake sturgeon in various waters and identify habitat requirements of young lake sturgeon; (3) Tag adult lake sturgeon in spawning runs to determine lake sturgeon movement, composition of spawning stock, and degree of homing.
This study is primarily focused on determining the current distribution and status of populations in northern Michigan by capturing adults and larvae during the spring spawning period. The study has been expanded to include lake sturgeon tagging by commercial fishers when fish are incidentally captured in commercial fishing gear. Juvenile lake sturgeon work has included tagging and radiotelemetry in Portage Lake and the Michigan DNR began stocking lake sturgeon fingerlings in the Ontonagon River in an effort to reestablish a self sustaining population in that river system.
Two of nearly 3,000 lake sturgeon released into the Ontonagon River, MI in October, 1999.
