Last Seen:

❋ The Zebra Mussels were originally from the Caspian Sea in Europe. Arriving in the late 1980s, Zebra Mussels were first seen in the ballast water of ships. However, now they can be found in the United States and Canada. They have even spread south of the Gulf of Mexico!

Identifying Characteristics:

❋ The zebra mussel us identified by the striped pattern of its shell. Color patterns can vary to the point of having only dark or light colored shells and no stripes. It is typically found attached to objects, surfaces, or other mussels by threads extending from underneath the shells.

Police Attempts:

❋ A test using liquid fertilizer to kill the invasive species was successful.

❋ Some lakes have been drained to allow frost to get all the way down into the mud to kill  them.

❋ Lakes that are infested with this species have been put under quarantine.

❋Citizens are told to clean, drain and dry their boat and equipment after boating in an area infested with these mussels.

Suspected Hideouts:

The Zebra Mussel tends to stay in the area of waterways.

Crimes Committed:

❋ Zebra Mussels eat lots of plankton, which means competing for food with fish every single day.

❋ Zebra Mussels colonize inside pipes and can clog them up, making it difficult for water to filter through.

❋ Every year it costs the Great Lakes $250 million to control zebra mussels in water intake pipes.


❋ If this species get eliminated recreational activity in lakes increase.

❋ The food chains that are being disrupted by this species can go back to normal.

❋ Native mussel species will begin to thrive again.
