Comparison of Four Electroshocking Procedures for Assessing the Abundance of Smallmouth Bass in Wisconsin Streams

摘要

The Upper Midwest region of the United States contains many streams with smallmouth bass (Micropterus dolomieu) populations. Many of these streams provide excellent fishing opportunities. But fisheries management of them is hampered by inadequate data on smallmouth bass population characteristics. In the paper, the authors compare results from four popular sampling approaches that involved sampling smallmouth bass with a 'stream shocker' (also known as a 'tow barge shocker'), a type of electroshocker widely used in Wisconsin and other States.
