Water recreationists, property owners asked to help search for aquatic nuisance species

News

Zebra mussels and other aquatic nuisance species may be on your boat lifts and docks, so the North Dakota Game and Fish Department is asking water recreationists and property owners to check before removing their equipment from area lakes.

Zebra mussels attach to hard surfaces that are left in the water for long periods of time, first settling in tight spaces and areas that are protected from sunlight, said Aquatic Nuisance Species coordinator Jessica Howell .

This can make searching for them in the lake difficult when there are few mussels present, Howell said.

“It makes it easier to do a thorough search on equipment when it’s taken out of the water in the fall,” Howell said. “Pay special attention to wheel wells, right angles on frames, and areas that are otherwise protected from sunlight. Feel for attached organisms that have small hair-like structures holding them in place. Small mussels can feel like rough sandpaper, and adults can be as large as two inches long.”

If you think you’ve found a zebra mussel, take pictures, write down any relevant information such as how many were found and where and report it online at the Game and Fish website at gf.nd.gov/ans, or email Howell at jmhowell@nd.gov, Howell said.

Zebra mussels are native to the Black and Caspian seas and were introduced to the U.S. in the mid-1980s. Since then, they have caused massive damage to infrastructure, increased costs to electric and water users, and altered the ecosystems into which they were introduced.

They were first discovered in North Dakota in the Red River in 2015 as a result of downstream drift from infested Minnesota lakes. Most recently, zebra mussels were discovered earlier this year in Lake Ashtabula. 

“Help stop the spread by reporting anything that seems out of place, and remember to clean, drain and dry equipment before moving between waters,” Howell said.
