How Much Electricity Does It Take To Shock A Fish: A Voltage Mystery Unveiled

To determine the voltage required to immobilize fish, it’s important to consider the type of electric current being used. When using direct current (DC), fish can be immobilized at voltage gradients as low as 1.0 volt per centimeter. However, when utilizing pulsed direct current (PDC), fish can be immobilized at even lower voltage gradients, as low as 0.6 volts per centimeter. This information sheds light on the varying electrical conditions necessary to safely and effectively immobilize fish, highlighting the advantage of PDC for this purpose.

Is it possible for fish to be fatally affected by electricity? Electrocution in fish results in the complete dysfunction of their brain, rendering the breathing reflex inactive. Consequently, fish perish due to a lack of oxygen, even while they remain unconscious. This process disrupts their normal physiological functions, ultimately leading to their demise. Understanding the mechanism behind how electricity affects fish can shed light on the potential environmental consequences and the importance of fish protection measures when dealing with electric sources in aquatic ecosystems.
