Accu Weather offers this basic article that explains what zebra and quagga mussels are doing to the Great Lakes ecosystem.
Here is the most important paragraph:
“The invasive species are doing significant damage on the ecosystem, particularly for native mussels. The zebra and quagga mussels anchor themselves onto the native mussels, which hinders their ability to function. The waters in the affected lakes are so clear because the algae and other organisms are being wiped out, which are supposed to provide a food source to many other aquatic creatures.”
During my years as a conservation writer, I’ve learned that too many people mistakenly associate clear water with a healthy ecosystem. Even worse, they think “the clearer, the better.”
Actually, ultra clarity indicates the base of the food chain is weak or nonexistent, and, as a result, fish and other aquatic creatures will have a tough time surviving. That’s why sport fisheries all over the Great Lakes are declining.
The same could happen in some inland fisheries as zebra and quagga mussels become established and their populations explode.
