ABSTRACT. Electrofishing has been a common fisheries tool in Missouri since the early 1970s. While electrofishing is a common tool, there has been little done in Missouri to standardize our fleet so consistent results are achieved. Two state-wide projects sampling smallmouth bass and big river catfish led to researchers attempting to standardize methods and equipment to hopefully standardize survey results. This effort led to a realization of deficiencies in our other equipment’s ability to replicate sampling results, operate safely, and even document the actual electrofishing settings in use during collections. In 2014, a committee was formed to address electrofishing equipment and safety and the committee decided that an attempt at standardization of equipment was appropriate at this time as well. The resulting electrofishing manual provides recommendations for control box and backpack shocker brands, wiring configuration, safety standards and anode resistance goals. The committee has also developed training to help biologists standardize their equipment, map their electrical fields, inspect boats for safety issues, and calculate anode resistance. Biologists are also provided information on power goals based on conductivity for consistent power usage to collect fish. Additional work is being conducted to determine electrofishing power thresholds for smallmouth bass, blue catfish and flathead catfish.
