Just in time for Minnesota's warm-weather boating season, state conservation officials Thursday released a list of waterways newly discovered to be infested with invasive species such as Asian carp, zebra mussels and Eurasian milfoil. Added were nearly two dozen lakes and stretches of the Mississippi and St. Croix rivers.

The new $3.8 million center at the University of Minnesota would focus on developing ways to fight aquatic species like zebra mussels and Asian carp.

Minnesota's fight against invasive species such as zebra mussels and Asian carp includes mandatory boat inspections and fines for failure to clean boats. To State Rep. Steve Drazkowski it's more government that takes away individual liberties.

Tougher laws aimed to prevent the spread of aquatic invasive species, like zebra mussels and spiny waterfleas, go into effect Sunday, July 1 -- doubling fines for Minnesota boaters who are caught violating the rules. The Department of Natural Resources says about 20 percent of boaters are not taking the basic precautions to comply with the laws. The new fines range from $100 to $500 dollars.

A new report, commissioned by The Nature Conservancy, says Minnesota spends nearly $8 million a year fighting aquatic invasive species. Minnesota Public Radio notes the fight is complicated because there is no single method to control all the different types of invasive species.

Got aquatic weeds hanging off your boat or trailer? The fine goes from $50 up to $100 on July 1. The DNR says it'll have 140 inspectors out checking compliance with the boating laws meant to limit the spread of invasive species such as zebra mussels and Eurasian watermilfoil.

The bill allows the DNR to setup inspection stations and issue tougher fines to help prevent the spread of aquatic invasive-species. Minnesota's 800,000 boaters would also be required to pass a training course. House lawmakers okayed the legislation Friday and Senators could vote on it this weekend.

The Army Corps of Engineers wants authority to close the lock and dam at Minneapolis' St. Anthony Falls at a moment's notice if invasive carp are found nearby. Supporters of the idea include the Minnesota DNR and Sen. Amy Klobuchar, who say stopping the migration of Asian carp up the Mississippi is needed to protect northern Minnesota waters.
