On Tuesday, April 28 at 7:00 PM, GBA invites you to go beneath the surface for a comprehensive look at the shifting ecology of Lake Huron and Georgian Bay.
Join us for an exclusive 90-minute webinar with Arunas Liskauskas — renowned biologist featured in the documentary All Too Clear — for an in-depth look at the fish populations of Georgian Bay. From walleye and trout to pike, salmon, and channel catfish, Arunas will walk us through the latest data on each species and explore what’s driving population changes across the Bay.
Arunas’s life and career have been defined by the waters he protects. He spent his youth learning to fish the waters of Severn Sound near Waubaushene, a passion that led him to pursue an Hon. BSc. in Fisheries Science and an MSc. in Fish Genetics at the University of Guelph.
He eventually returned to his “home waters” of Georgian Bay and Lake Huron, serving for over 35 years as a Management Biologist with the Ontario Ministry of Natural Resources (MNR). Having just retired this past March, Arunas is starting a new chapter of discovery—one that continues his lifelong mission to understand and protect the “everything fishy” in our Great Lakes.
In his presentation, “The Changing Ecology and Fish Communities of Lake Huron Including Georgian Bay,” Arunas will share decades of insights and data on:
Key Invasives – a look at the invasive species currently re-engineering the Bay’s ecology
Prey Fish – an update on the foundation of the food web—the small species that sustain the Bay’s top predators
Deep Water Fish – the latest trends and population data for Lake Trout, whitefish, and salmon
Near Shore Fish – insights into the species most familiar to coastal residents, including walleye, pike, muskie, and bass
Whether you are an avid angler, a shoreline resident, or a passionate conservationist, this is a rare opportunity to hear directly from a biologist who has spent 35 years monitoring our shoals and channels.
