"Evaluation of lake sturgeon (Acipenser fulvescens) populations in
Northern Michigan"
Supported through a
Federal Aid in Sport Fish Restoration Grant
Bucket of juvenile lake sturgeonPrinciple Investigator:
Edward A. Baker, Michigan DNR
Cooperator: 
Nancy A. Auer, Michigan Technological University
Study Objectives:
(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.
