Why are zebra mussels a problem in the Great Lakes?

zebra mussels are a huge problem because they harm Native Species. In order for a zebra mussel to live, it must attach itself to a hard object. ... Zebra mussels contribute to biomagnification—the toxins that they filter out of the water are concentrated in their bodies, and passed on to their predators.

How did zebra mussels make it to the Great Lakes?

The zebra mussel is native to Eastern Europe and Western Russia. The species was unintentionally introduced into the United States' Great Lakes through the discharge of contaminated cargo ship ballast water.

Do zebra mussels bite?

Just like many other bivalves, zebra mussels are filter feeders. They eat by sucking in water, filtering out all the particles, and spitting out what they do not want (along with the water). For us, it would be like turning a piece of cake into crumbs and “breathing” them in instead of just taking a bite.

Do zebra mussels hurt fishing?

Zebra mussels are one of the most devastating invasive species in North America. When they become established in an environment, they alter food webs and change water chemistry, harming native fish plants and other aquatic life. They clog pipelines used for water filtration, render beaches unusable, and damage boats.
