The release indicates that in addition to the Rotenone action, simultaneous electrofishing and commercial netting will take place between the downstream block net and Acme Bend. Electrofishing and netting will allow for an expansion of the area sampled and a comparison of conventional methods with Rotenone sampling. The waterway will be treated in one day, and the fish recovery phase of the operation will last for four to five days. During that time, the FWS, Illinois DNR, and other participating agencies will aim to recover as many fish in the application area as possible to determine the abundance and type of fish present in the treated area.
The release says, "Knowledge of the population size and location of possible Asian carp in CAWS is important data that will inform biologists and decision makers on selecting and prioritizing appropriate future actions to keep Asian carp from moving into Lake Michigan." The RCC includes representatives from the City of Chicago, Illinois Department of Natural Resources, Metropolitan Water Reclamation District, U.S. Army Corps of Engineers, U.S. Coast Guard, U.S. EPA, U.S. Fish and Wildlife Service, U.S. Geological Survey, the Great Lakes Fishery Commission and the Indiana Department of Natural Resources.
