Grass Carp Removal in Lake Erie: Lessons from a Five-Year Control Plan
Abstract
"Invasive grass carp (Ctenopharyngodon idella) were discovered to be reproducing in Lake Erie tributaries in 2015, prompting management agencies to develop an adaptive control plan. The action plan is aimed at preventing grass carp from attaining densities which could adversely affect Lake Erie ecosystems. Initial control began in 2017 and has increased to form a multiagency, interjurisdictional team of managers and researchers. Since implementation, over 800 adult grass carp have been removed from Lake Erie waters. A modeled abundance estimate for the Sandusky River shows no increase since implementation of control in this important spawning location. Mortality rate has increased over the same time period, suggesting that removal is having an impact. The early success of the program rests on cooperation across participating management and research organizations, allowing for a larger scale response than any one organization could deploy.
