Lake sturgeon (Acipenser fulvescens) have successfully returned to the waters of Green Bay and Lake Michigan after years of stocking efforts.  During Spring, spawning runs of lake strugeon occur in the Menominee, Oconto, Peshtigo, and Fox Rivers where the fish typically swim up to the first barrier to find suitable spawning habitat; small, well aerated rock.  AEFL students have monitored larval drift events in the Menominee and Oconto Rivers to assess recruitment and to determine what environmental variables are associated with the onset of larval drift.
