The Department of Natural Resources says it is serious about stopping the spread of aquatic invasive species.
“We are setting the expectation of the angling and boating public that they will follow the laws to prevent the spread of aquatic invasive species, that they will be checked for AIS violations and that they will cited if a violation is found,” Lt. Col. Rodmen Smith, DNR enforcement division assistant director.
Increased patrols were set to begin during the weekend walleye opener.
Minnesota law prohibits the possession or transport of any invasive species, even if a boat owner does not know about a hitch hiker.
Such species include zebra mussels, Eurasian watermilfoil and spiny waterfleas.
Fines can range up to $1,000.
