AIS News Releases

Prevent the Spread

June 20, 2018

Announcing 6 new PSA’s on Aquatic Invasive Species
A creative series of six, 30-second public service announcements and accompanying social media posts have been professionally produced to gain attention on aquatic invasive species while sharing actions people can take to stop the spread. The videos and social media posts are available for download to be used and shared across Minnesota and the Midwest.

This video series is available as a free resource thanks to funding from the Minnesota counties of Douglas, Pope, Otter Tail, Cass, Becker, and Aitkin along with the Crow Wing County Lakes and Rivers Alliance and the Pelican Lakes Association in Crow Wing county.

The impacts from aquatic invaders like Eurasian watermilfoil, starry stonewort, zebra mussels,and spiny waterflea are hitting home in Minnesota. The quality of Minnesota lakes and rivers is threatened by these invasive species that hurt enjoyment of our lakes, property values, tourism, fish populations, cause algae blooms, fouled beaches, and wreak economic havoc by clogging boat motors and water supply and drainage systems.

It is vital to our current and future local, state and regional economy to greatly increase our education efforts to inform the public about aquatic invasive species and steps to prevent their spread. To receive files to download and share or learn more, please contact Erika Gilsdorf at the contact information above.

“As a former AIS inspector, it was my goal with this project to provide a fresh and creative ‘hook’ around aquatic invasive species messaging and the actions people can take to stop the spread. The response with this series has already been phenomenal. We’re excited to be part of a multi-county project that can offer these videos and social media posts at no charge to lake associations, organizations, businesses, government agencies, and individuals to share.”

Erika Gilsdorf, Producer

The videos were produced in Detroit Lakes, Minnesota by LB Video Productions, a division of Leighton Broadcasting.

Fall Prevention of the Spread of Aquatic Invasive Species
Green and Calhoun Lakes in Kandiyohi County are now designated by the Minnesota DNR as infested with zebra mussels, an aquatic invasive species (AIS). This year, a decontamination unit for watercraft and water-related equipment was available from May through September at the County Park 4 (Saulsbury) public water access, and staff members provided decontamination services free-of-charge. The decontamination unit has now been winterized and placed in storage until next spring, although there’s still a significant risk of spreading AIS during the fall and winter months. As water equipment (e.g. docks, rafts, lifts) are removed for the season, inspect and remove any attached invasive species. It may be necessary to run your hand over smooth surfaces to detect juvenile mussels which may feel like gritty sandpaper under your fingertips. It is illegal to transport AIS, dead or alive, and may result in a fine. If you find invasive species on your equipment, you have two options. You may download a transport permit from the MN DNR, which allows you to move the equipment to a single location where it can be decontaminated and must be completed, signed, and kept in possession during travel to avoid a citation. Or, allow equipment to dry for 21 days and decontaminate before leaving the property. 

Fall hunting activities may also pose a risk of spreading AIS. Although natural resource professionals do not view the smooth exterior of decoys as a significant risk, damaged decoys that leak should be drained completely. Zebra mussel larvae (veligers) and adults can survive in these wet and humid environments for up to 27 days. Lowering your boat’s motor to drain water helps, but the only way to flush remaining water is with a decontamination unit. Ensuring waders, anchors, boat trailers, and all water-related equipment is drained and free of mud, plants, and water will help prevent your favorite hunting grounds from becoming infested with AIS. Be safe, responsible, and enjoy the season!
