Montana Warden Stops Tugboat Carrying Invasive Species Near Anaco

A Montana Fish, Wildlife & Parks warden stopped a driver transporting a mussel-infected tugboat close to Anaconda last week and discovered a large amount of Aquatic Invasive Species (AIS). The boat, which had most recently launched in Lake Michigan, was headed for Puget Sound in Washington.

According to FWP officials, not only were a large number of mussels discovered but also barnacles, suggesting the boat was likely in salt water prior to Lake Michigan.

The warden ordered the driver to return to the inspection station. The boat spent two days out of the sea; hence, some of the mussels might have been still viable.

With the size of the vessel, everything was decontaminated except for the engine. A follow-up examination will be required since the boat was locked to the trailer.

The driver also bypassed inspection facilities in Hardin and Broadus. This makes the tugboat the sixth watercraft this year to be found infected with invasive species.

FWP is reminding everyone that all watercraft must stop at all inspection sites they encounter in the Treasure State.

Before launching in Montana, non-residents and returning citizens must have their watercraft inspected. Before transportation, watercraft also have to be drained of all water.

"AIS enforcement continues to be a priority for Montana game wardens. We will continue to do our part in this ongoing fight," said FWP Game Warden Chief Ron Howell.
