MINNEAPOLIS (AP) - More boat inspectors are on patrol at Minnesota lakes and rivers to help stop the spread of invasive species, including zebra mussels.

Counties are reportedly beefing up inspections, thanks to $10 million in state funds.

Greg Salo, of the Department of Natural Resources' enforcement division, says state inspectors will also be more aggressive this year. Instead of warnings, they'll give out more citations. He says that has to be done to change boaters' behavior.

More than 500 Minnesota rivers, lakes and wetlands are listed as infested, including more than 200 with zebra mussels.
