Invasive Species – Great Lakes Superior Aquarium

Invasive Species Game

Terminology

Educational displays at Aquarium

Keeping our water and land free of invasive species takes all of us doing our part. Considering what we dump into the waterways and ground before hand can make all the difference.

Visiting the Great Lakes Aquarium helpedĀ  us learn more about native vs. invasive fresh water aquatic plants and fish. Through games students simulated how aquatic invasive plants and fish change the natural balance. They either eat too much of a plant needed by another native fish or grow too fast overtaking other plants that would typically grow in that environment. Any change affects everything. Eventually the native species can not compete and either die away or move.

It was particularly interesting to learn that gold fish dumped into a small pond negatively affects the pond tremendously. Goldfish eat a lot, changing the vegetation and ability for other animals to breed and grow. If you have a goldfish and are unable to care for it it is best to give it to someone else to take care of rather than a near by pond. A pond near to UMD had to be drained completely , cleaned and refilled because of theĀ  of gold fish population taking over the native species and the connection of the pond stream feeding into Lake Superior.

Release Tanks at Fishery, Bad River Reservation, Odanah, WI

About 2,000 Coastal Brook Trout are raised from eggs and released when a year old into rivers and streams.

The health of our water and land was part of each lesson and activity. While visiting in Odanah we toured the reservations fishery. The fishery raises Walleye and Coastal Brook Trout from eggs for up to 7 years and then releases them. Each tank held a specific species and age of fish.

We also spent time swimming in Lake Superior. As expected it was cold and refreshing.
