摘要：

An electrofishing power supply was developed to deliver up to 4. 5 kW to stun fish. Electrofishing makes use of electrical fields in the water to stun fish so they can be netted, examined, counted, and returned to the water as part of a fish census. It is important that the fish not be injured in the process. The control makes it possible to use a 3 phase 230 V, 4. 5 kVA, 0. 9 PF, 180 Hz alternator and deliver an output to the electrodes of up to 500 V and up to 15 amperes as ac, dc, or as a pulse train with a frequency from 5 to 120 Hz and with an ″on time″ from 10 to 50% of the period. Electrical safety was carefully considered in the design. The system is mounted in a 16 or 18 foot aluminum flat bottom boat with electrodes at the bow and sides of the boat.
