Description
Дл направлени рыбы к аноду используют переменный ток с посто нной составл ющей , дл отпугивани рыбы в зону облова и от охран емого участка воды используют переменный электроток.To direct the fish to the anode, an alternating current with a constant component is used, and an electric current is used to scare away fish into the zone of fishing and from the protected part of the water.
Одновременное воздействие на рыбу импульсного электротока и потока акустических колебаний отпугивает рыбу из зоны воздействи при весьма слабых напр женност х пол электрического тока, иногда лежащих за пределами болевого раздражени рыб.The simultaneous effect on the fish of a pulsed electric current and a stream of acoustic oscillations scares the fish out of the zone of influence with very weak voltages of the electric current, sometimes lying outside the limits of pain stimulation of the fish.
