Development of Operational Protocols for Electric Barrier Systems on the Chicago Sanitary and Ship Canal: Induction of Passage-Preventing Behaviors in Small Sizes of Silver Carp.

摘要

The Chicago Ship and Sanitary Canal (CSSC) is a navigable channel that connects Lake Michigan to the Mississippi River Basin. Electric barrier systems have been constructed to create waterborne electric fields within the CSSC to prevent Asian carp from swimming from the Mississippi River basin through the canal into the Great Lakes. A laboratory study was conducted to determine which characteristics of the waterborne electric fields of pulsed direct current (pulsed DC) are effective at immobilizing (preventing passage of) small Asian carp that enter the electrified zone. This experiment was the first step in a comprehensive study to determine optimum operating parameters for electric barrier systems in operation to prevent dispersal of aquatic nuisance species -- including Asian carp -- through the CSSC and other aquatic systems.
