All our invited to the next installment of our popular monthly lecture series. We are excited to welcome Dr. Ellen Marsden as our featured speaker in September with her lecture entitled, "Lake Trout Restoration in Thunder Bay."
In 2010, a team of fisheries researchers, managers, and other collaborative partners, including Thunder Bay National Marine Sanctuary, built a series of 29 rock piles to serve as artificial reefs in Lake Huron's Thunder Bay. After the loss of some natural habitat due to cement kiln dust, the constructed reefs were intended to give lake trout a place to spawn, although several other fish species such as bass, walleye, and whitefish are also attracted to the reefs.
Dr. Ellen Marsden was part of this large effort. In this lecture she will explain the background behind the reef project. She will also share how scientists have been using scuba diving, fish tracking, and underwater videos to study fish behavior and how the reefs benefit fish populations.
Sanctuary divers and vessels supported this effort, contributing to the overarching goal of preserving the Great Lakes for this and future generations. There is an exhibit in the Great Lakes Maritime Heritage Center that highlights this impactful project.
Dr. Ellen Marsden received her doctorate in Fisheries in 1988 from Cornell University. In 1990, she joined the Illinois Natural History Survey as director of the Lake Michigan Biological Station, then moved to the University of Vermont in 1996. She studies restoration, ecology, behavior, and genetics of fishes in the Great Lakes, primarily focused on lake trout.
This event is free and will take place in the theater of the Great Lakes Maritime Heritage Center in downtown Alpena. Doors will open at 5:30pm.
