Development of Electrofishing for Fisheries Management, Electrofishing, broadly defined as the use of electricity to capture or control fish, was envisioned in an 1863 British patent applica-tion by Isham Baggs Not until the 1920s, when large, stationary generators were available, did electrofishing applications (ie, fish , trol of circuit resistance A precursor of modern pulsed direct current ,Longline fishing gear, This completes the electric circuit which is operated by the individual at his convenience One simple discharge is enough to stun the animal The raising of a large fish is easy and safe The first advantage is operational The raising and manipulation on board of these large species is both complicated and dangerous for the crewAUSTRALIAN CODE OF ELECTROFISHING PRACTICE, grounds the frame to the output circuit The frame however must still be earthed via an earth stake for shore mounted units, or by grounding to all other metal objects within a boat, whether the boat is metal or non-metal In non-metal boats, the outboard motor must be grounded as well Electrofishing generators must be clearly labelled and mustELECTROFISHING POLICY, S Lighting circuit shall be 120 volts or less (prefer 12 volts) Spotlamps must be shielded by a sturdy, non-conductive cage and it is recommended that they be covered by a removable face guard 60 All branch circuits must be equipped with a fuse and/or circuit breaker enclosed in a weatherproof enclosure per NECA standards44 Use of Electrofishing for Capturing Invasive Fish, Electrofishing captures only some of the fish encountered by the electric field because a proportion display the primary avoidance response before encountering the ranges of voltage gradients that produce galvanotaxis, narcosis, forced swimming or tetany (Figure 45).
