Isle Royale

The 85,000-gallon Isle Royale exhibit contains fish found in the Great Lakes. This exhibit is a two story tank divided into 3 sections.

The largest of the tanks features native fish found swimming in colder, deeper waters of Lake Superior such as coaster brook trout, lake trout, lake sturgeon, burbot, long nose suckers, and walleye, as well as introduced species such as Kamloops and Steelhead rainbow trout, brown trout, and salmon.

Just around the corner is a warmer tank where you will find muskies, carp, and bass alongside fish that represent the Lake Michigan aquatic community.

The final tank features additional temperate species such as pan fish that call Lake Erie home.
