Hello,

Thank you for using MSU Extension Ask-an-expert with your invasive species question.  several lakes in the state have used diver assisted harvesting services to remove invasive species from lakes with varying degrees of success. One thing I do know is that this process does require an EGLE permit because of its lake bottom disturbance activities.  

You can get some more information about the process at these websites: Management of Aquatic Invasive Species Using Diver Assisted Suction Harvesting (DASH) (uprcd.org) http://www.uprcd.org/downloads/diver_assisted_suction_harvesting_of_aisgajewski.pdf
