Invasive mussels found on boat at CSKT AIS check station

Second infested boat seized at Ravalli station this year

Thursday, October 10, 2019/Categories: AIS News, Watercraft Inspection Stations/Tags:

A boat from Chicago bound for Seattle was quarantined and decontaminated at the Ravalli watercraft inspection station operated by the Confederated Salish & Kootenai Tribes (CSKT). An inspection conducted by Lacey Burke, Mitch Parker and JaBlue Arlee found adult zebra mussels attached to the vessel.  The boat came from mussel-infested waters and had been out of the water for less than two weeks. 

The Chicago boat stopped at watercraft inspection stations in Wibaux and Anaconda but the mussels were not detected.  Montana AIS protocol requires a contaminated vessel to be quarantined and decontaminated with hot water to remove and kill invasive species prior to being released from an AIS check station.  It is illegal to transport mussels, dead or alive, into or within the state of Montana. This is the second mussel-infested vessel that has been seized at the Ravalli AIS check station this year and the 15th mussel boat intercepted in Montana.  

Montana Fish Wildlife and Parks (FWP) and partner organizations operate watercraft inspections state-wide to prevent the transport of aquatic invasive species (AIS). Stations increasingly are operated through contract with local entities to provide increased local oversight and local community involvement. The watercraft inspection station at Ravalli is a partnership between CSKT and FWP and has been very successful operating the inspection station this year. As preparations are made for the 2020 season FWP and partners are working together to identify strategies to increase oversight, management and enforcement at inspection stations to ensure boats like this are not missed in the future.

An adult female zebra mussel can release a million eggs each year.  Mussels have detrimental impacts on recreation and infrastructure when they attach to underwater surfaces.  Flathead Lake is one of the largest and cleanest freshwater lakes in the country.  Boaters can stop the spread of aquatic invasive species by making sure watercraft is clean, drained and dry. Let’s work together to help stop the spread of invasive mussels. (https://vimeo.com/224323940)
