March 21 Speaker Mark Luttenton to Review Au Sable Trout Movements

Mark Luttenton will present his findings from a large-scale study of trout movement and habitat use in Michigan’s Au Sable River. Using radio telemetry, Mark’s group tracked more than 50 trout over two years to determine their daily and seasonal movements, and what types of habitat trout prefer.

Mark is the Associate Dean of the Graduate School, professor of biology, and research associate at the Annis Water Resources Institute, Grand Valley State University in Michigan. During his nearly 30 years at GVSU, he has conducted research on fish, aquatic insects, clams, zooplankton, phytoplankton, and benthic algae. His research has included examining the impacts of invasive species (e.g. New Zealand mud snails), community metabolism, stream food webs, salmonid population genetics, juvenile steelhead survival in the Muskegon River, trout movement, and aquatic fungi as a source of compounds to control pediatric cancer.
