Our MBS™ and Trident Boat Electrofishing Series are 240 VAC generator-powered electrofishing systems that are a powerful tool for accurate sampling over a wide range of water conductivity. Proven and trusted performers, ETS equipment was developed with technical support from the University of Wisconsin, U.S. Fish & Wildlife Service, Wisconsin Department of Natural Resources, and many other federal and state agencies.
ETS Electrofishing Systems has provided quality boat, stream barge, and backpack electrofishing units to federal, state, and private agencies for over 25 years. We offer customized equipment with short lead times at the most competitive prices in the industry.
More than 900 of our systems are in service in the United States, Canada, Mexico, and Australia, including over 300 boat systems. ETS control boxes are fully and quickly repairable. We offer a RUSH REPAIR OPTION at no added cost.
The USFWS completed a comparative evaluation of electrofishing control boxes, available online. Based upon that evaluation and recommendations from other agencies, a consortium of three western states have standardized on our unit for the Colorado River Recovery project. They currently have 28 boxes in use. The states of Illinois , Wisconsin, and other states have also standardized on our boxes for most regions.
All ETS Electrofishing systems are customizable to meet your organization’s needs. See detailed specifications and descriptions of our lake electrofishing equipment below. Boat hulls, booms, droppers, generators, and more are available through our custom boat manufacturers – we can supply a total system. All systems include a limited one-year parts and labor warranty.
