Funding was appropriated in 2012 for the MInnesota Aquatic Invasive Species Research Center (MAISRC). Dr. Peter Sorensen is the researcher heading up this center.  The focus will be on Carp and Zebra Mussel research.

Using Innovative Science to Identify Solutions to Minnesota’s AIS Problems

Minnesota’s lakes and streams are increasingly threatened by aquatic invasive species (AIS) and we have few ways to address these threats. In 2012, the Minnesota legislature appropriated funds to create an Aquatic Invasive Species Cooperative Research Center at the University of Minnesota, in collaboration with the Commissioner of Natural Resources (DNR).

The Center’s mission is to develop biologically and economically sound solutions to control key aquatic invasive species affecting Minnesota’s waters.  Our strategy is to develop an in-depth understanding of the biology and ecology of key AIS to determine if there are weaknesses in their life histories that can be targeted for control and eradication. The Center will also use modeling and risk analysis to help state AIS managers determine the most efficient and effective application of any of the Center’s findings.

Quagga Mussel Veliger Research by Dr. David Wong :: Published January 2013


Some notable items in the findings and conclusions:

  1. Veligers can survive up to 27 days in any wet or damp portions of a boat.
  1. After draining, watercraft coming from infested waters should be quarantined long enough to kill veligers in any retrained residual water before launching in another water body particularly during cooler seasons if residual water cannot otherwise be decontaminated.
  1. Veligers are potentially a greater threat than adult mussels to uninfested waters as they are invisible to the eye and can be transported in even small volumes of retained water in trailered watercraft.
  1. Veligers may survive overland transport in residual water of trailered boats during transport to any location in the continental 48 states that could be reached within < 5 days in summer and <27 days in autumn and spring in MN.
  1. Veligers can be overlooked even during the most careful of boat inspections.
  1. Most areas inside a boat cannot be fully drained since the drain openings are above the lowest level of bilge, ballast tank or other containment areas.  Even when an opening is at the bottom of the tank, there is still a flange on the inside of the tank that can prevent complete drainage.
  1. If a boat were efficiently drained but not dried of residual water, an estimated 8 L of water may be retained on board based on the vessel decontamination experience of Utah's Aquatic Invasive Species Biologists for more than 30,000 inland boats.
  1. Any veligers retained in undrained residual water could then be released after launching and infest a new water body.
  1. Because it is impossible to drain all sources of standing water in many recreational boats without extreme effort, the risk of survival of veligers in retained water is high regardless of spring, summer or fall temps in MN.
