How do zebra mussels affect walleye fishing?
These results demonstrate that zebra mussels and spiny water flea influence the growth rates of age-0 walleye and that a wide range of food resources and habitats support walleye in these lakes. Declines in growth rates of young walleye are an early signal of potential negative effects on walleye.
How many Minnesota lakes are infested with zebra mussels?
How many lakes and rivers are listed as infested? About 8% of Minnesota’s more than 11,000 lakes are on the infested waters list. Less than 4% of Minnesota lakes are listed as infested with zebra mussels. As of November 2021, we have confirmed zebra mussels in 270 lakes and wetlands.

How did zebra mussels get into Minnesota lakes?
People spread zebra mussels primarily through the movement of water-related equipment. Mussels attach to boats, docks, swim rafts and boat lifts. They can also attach to aquatic plants.

How long does it take zebra mussels to ruin a lake?

Currently, there are more than two hundred and thirty lakes that have zebra mussels. Much of this recent dispersal can probably be attributed to recreational activities such as boating and fishing.

Zebra mussels can render beaches unusable, clog water filtration pipes, and destroy boat engines such as in example pictured above. Although small, zebra mussels cause big trouble.
How do lakes get rid of zebra mussels?
A 2% chlorine bleach solution is effective at killing zebra mussels when cleaning boating equipment or other gear away from waterbodies. A bacterial formulation is currently being researched, which uses a native soil bacterium to kill zebra mussels without causing other damage to the ecosystem.
