If you want to shock fish, you can do so by using a car battery. Just be sure to use the correct size battery and make sure the terminals are properly insulated. Here’s how:

  1. Park your car near a body of water with plenty of fish in it.
  2. Connect the positive terminal of the battery to one side of the fish’s head and connect the negative terminal to its tail.
  3. Turn on your car and wait until the engine is running smoothly before driving away. The sudden noise and vibration will startle the fish, causing it to swim away in surprise. ..
