Page 4: Introduction
Our years of experience in manufacturing electrofishers has helped us to produce the most complete line of generator powered electrofishers ever offered. Ranging from 1.5 to 9kW, Smith-Root manufactures electrofishers to handle all fresh or brackish water conductivities. A complete electrofishing system consists of an engine, a generator, an electronic pulsator, an anode, a cathode, cables, and switches. -

Page 20: Introduction To Electrofishing
GPP ELECTROFISHER USER’S MANUAL INTRODUCTION TO ELECTROFISHING For many years it has been known that fish react to electric current passed through water. Electricity was first used for fishing in 1863 when a British patent was granted. Major efforts to apply electricity as a tool in fisheries management did not occur until after 1950. Since then detailed studies have been made on the physiological effects of electricity on aquatic organisms. - Page 21 The current passing through the larger model GPPs. effective. a fish decreases as the power The Smith-Root 7.5 GPP flow decreases.
