MINNESOTA DEPARTMENT OF NATURAL RESOURCES Feasibility Study to Limit the Spread ofZebra Mussels from Ossawinnamakee Lake monitoring procedures, specific objectives. that relate to management of the current lake population are recommended in Section VI. Table V-2. Summary of Potential Management Alternatives Type of Management Alternative Prevention through Education and Public Outreach Detection and Monitoring Rapid Response Alternatives Tolerance ofANS Implementation ofControl Methods Impletmentation and/or Maintenance Issues It is important to educate the public and recreational users about the impacts ofzebra mussels and guidelines that can be followed to aid in prevention ofspreading. Proper equipment and training must be provided for appropriate personnel to facilitate early detection and regular monitoring procedures. A coordinated rapid response plan must be developed that can aid management personnel in the event ofdetection or establishment ofzebra mussels. Management plans must address the systems tolerance of zebra mussels in order to determine ifprevention or elimination procedures are required. Specific technological, physiological, or biological control methods can be implemented to control the spread of zebra mussels. Prevention through Education and Public Outreach It is important to promote public awareness and understanding of zebra mussels and their potep.tial impacts to the ecological and economic health of Ossawinnamakee Lake, Pelican Brook, Pine Brook, and the Upper Mississippi River. Outreach programs that promote commercial and recreational practices to prevent the spread of zebra mussels are also important. These practices include the proper disposal of live bait, inspection of any boats or other equipment that is placed in infested waters, and proper cleaning procedures for removal ofzebra mussels. In addition, frequent boaters should be educated on anti-fouling paints and coatings that can be utilized to prevent zebra mussel attachment. The ANS Task Force public awareness campaign in an effort to control recreational spread of aquatic nuisance species has initiated the program entitled "Stop Aquatic Hitchhikers." This program encourages recreational users to not only identify ANS present in their surroundings, but also follow a short list of guidelines every time they leave a lake, stream or coastal area. Figure V-3 gives a short de,scription ofthese guidelines. V-16 Review oCPotential Control Methods

Clean all recreational equipment. www.f'roteetYourWaters.llet hen you leave a body of water: • Remove any visible mud, plants, fish or animals before transporting equipment. • Eliminate water from equipment before transporting. .. Clean and dry anything that comes into contact with water (boats, trailers, equipment, clothing, dogs, etc.). • Never release plants, fish or animals into a body of water unless they came out of that bod of water. Figure V-3. Stop Aquatic Invaders Graphic (courtesy of www.protectyourwaters.net) The Model Rapid Response Plan for Great Lakes Aquatic Invasions (Draft: July 17, 2003) represents the development of a model rapid response plan for Great Lakes aquatic invasions. The goal ofthis project was to develop a model rapid response plan as part of an overall regional effort to enhance ability to anticipate, prevent and respond to new aquatic invasions of nonindigenous species in the Great Lakes-St. Lawrence region and could be modified and adapted for limiting the movement ofzebra mussels into the Upper Mississippi River System. Integral to rapid response planning is a communication and organizational structure that determines how to disseminate information, as well as authority and leadership roles, coordination, cooperation and partnerships. Legislative authority and policy also need to be taken into consideration under this component. A clearly defined communication structure will facilitate timely information exchange among the appropriate entities in the rapid response network. If a rapid response is deemed appropriate, information needs to be communicated to appropriate stakeholders to engage them in the process. Other states, provinces, agencies, the media and the public need to be made aware of the situation and associated activities as appropriate. Detection and Monitoring Early detection and monitoring efforts are critical to the discovery ofnew introductions ofzebra mussels and in accurately tracking the spread of existing invasions. Detection of this nonindigenous aquatic species is essential because zebra mussels have rapid dispersal and growth rates that could inhibit control strategies if not implemented promptly. Monitoring can be utilized to determine the specifications for developing control methods, such as frequency and urgency of necessary treatments.
