Nicholas S Johnson, PhD
Nicholas Johnson is a Research Ecologist based in Millersburg, MI.
I study fisheries with a focus on invasive species control and native species restoration in the Great Lakes. My work links the experimental sciences of sensory ecology, physiology, and behavior with applied fish population dynamics and adaptive management to inform policy. I became a research ecologist with USGS, Great Lakes Science Center, Hammond Bay Biological Station in 2009, serve in adjunct appointments at several universities in Michigan, and am an assoicate editor of the Journal of Great Lakes Research. My research is mostly in collaboration with the Great Lakes Fishery Commission where I am a member of several Task Forces and Coordinator of the Supplemental Sea Lamprey Control Initative. Research brings me the most joy when done with students and when my neighbors in Northern Michigan understand why it matters.

Survival and metamorphosis of Sea Lamprey in Lake Erie tributaries
Adult sea lamprey abundance in Lake Erie increased during the past decade, exceeding pre-control levels and causing extensive mortality on some strains of stocked lake trout (Markham 2015). Control agents speculate that this increase may be due to an uncontrolled larval sea lamprey population in the St. Clair River because other known sources of larval sea lampreys are regularly treated with...
