How do lakes get rid of large carp populations?



  1. 0 Votes

    Common carp are known to cause problems in lakes because, as bottom-feeders, they stir up the lake bottoms, affecting water clarity and rooting up plants, and ultimately destroying marshland habitats. In Illinois, where Hennepin and Hopper lakes are severely affected by carp, the Department of Natural Resources and the Wetlands Initiative have launghed a year-long rehabilitation project to rid the lakes of these troublesome fish. By draining the lake, the other water-faring and marshland creatures will migrate into the Illinois river while workers remove the carp, treat the soil with a tropical plant extract called rotenone (commonly used to manage invasive fish populations). Once the lake is refilled, the displaced salamanders, fish, frogs, and turtles will return.

    This method has been used in the past in other areas and has proven to be successful so far, with no resurgence in carp populations to date.
