Electrofishing plays a vital role in surveying fishes, monitoring and determining the size of fish population and species. This study entails the procedure for the design and construction of an electrofishing equipment. The study highlights the consistent and harmless efficient capture method that electrofishing constitutes. It highlight the growing endorsement of electrofishing as a safe and cost-saving fish sampling gear and method for degrading the incidence of inadequacies, fatalities and economic loss in fisheries management. The study derives its impetus from “local action paradigm” which has its principles hinged on galvanotropisms to the action of electricity on local nerves and muscle fibers of the target population.
