Researchers from the Minnesota Aquatic Invasive Species Research Center periodically present on their research findings via webinar. View recent webinars below, and stay tuned for more in the future!
We estimate willingness to pay for local aquatic invasive species lake management in the form of a daily lake access fee by conducting summer lake surveys in Minnesota, USA. We also examined recreationists’ visit motivation, and aquatic invasive species perceived risk, knowledge, and awareness of problem. We estimate mean willingness to pay to be $10.41 per day, which did not differ significantly by lake. Perceived risk, awareness of problem, and visit motivation were significant in predicting willingness to pay, which could have important ramifications for aquatic invasive species management. All questions that were asked during the live session were saved and answered by Dr. Levers and Dr. Pradhananga in this document.
Common Carp Control
Common carp are one of the most widespread invasive fish globally. In this talk, Przemek Bajer, a MAISRC Research Assistant Professor presents a brief history of common carp introductions around the world, explains their impacts on lake ecosystems and shows some of the new and innovative tools we use in carp management. These tools will include autonomous systems for removing carp during spawning migrations, and conditioning strategies that exploit carp’s social behaviors to train them with food and remove.
Spiny waterflea in Lake Mendota
MAISRC postdoctoral research fellow Jake Walsh presented the results of his study of the ecological and economic impacts of spiny water flea on Wisconsin’s Lake Mendota. Additional resources provided during the webinar can be found here.
