Description

(54) СПОСОБ НАПРАВЛЕННОГО ПЕРЕМЕЩЕНИЯ РЫБЫ(54) METHOD OF DIRECTED FISH MOVEMENT

продолжительности в пределах 1-3 мин, что создало возможность уменьшить в несколько раз величину тока посто нной частоты.duration within 1-3 min, which made it possible to reduce the magnitude of the current constant frequency by several times.

Подача в воду такого импульсного тока сопровождалась иривлечением рыб к аноду и удерживанием их у него.The flow of such a pulsed current into the water was accompanied by the ignition of the fish to the anode and holding them to it.

Способ будет наиболее эффективным дл  скоплени  рыб, характеризуемого различным видовым составом и некоторым разбросом размеров и состо ний, так как он основан на использовании полей электрического тока, характеризуемых изменением частоты в области наибольшей раздражаемости рыб, производимым ступенчато и нерегул рно за заданное врем .The method will be most effective for the accumulation of fish, characterized by different species composition and some variation in size and condition, since it is based on the use of electric current fields, characterized by a change in frequency in the region of greatest irritability of fish, produced stepwise and irregularly over a given time.

4 Предмет изобретени 4 Subject of the invention

Способ направленного перемеш,ени  рыбы путем воздействи  на нее периодическим импульсным электрическим током, подаваемым в виде отдельных циклов, отличаюшийс  тем, что, с целью уменьшени  адаптации рыб и повышени  эффективности воздействи  иа них электрического тока, ступенчато измен ют частоту иодачи импульсов тока от 1 до 1000 Гц, а в процессе подачи тока измен ют очередность ступеней частот внутри каждого цикла и длительность подачи частоты иа каждой ступени, при этом продолжительность цикла составл ет 1-10 мин.The method of directional mixing of fish by acting on it with a periodic pulsed electric current supplied in the form of separate cycles, characterized in that, in order to reduce the adaptation of the fish and increase the efficiency of their electric current, the current pulse iodine frequency changes from 1 to 1000 Hz, and in the process of supplying current, the sequence of frequency steps within each cycle and the duration of the frequency supply at each stage are changed, the cycle duration being 1-10 minutes.
