A Step-by-Step Tutorial Building Your Own DIY Fish Shocker Machine

Section 1: Conceptual Understanding of Electrofishing

Understanding electrofishing is a prerequisite to beginning the building process. Fish can be stunned with an electric current, making them easier to catch or study, in a process known as electrofishing. The fish shocker machine is the heart of this method since it produces the electrical field.

Section 2: Materials Collection

Let’s begin by gathering the components for your homemade fish shocker machine. You’ll require:

  • Choose a 12-volt DC power supply for reliability and portability.
  • In order to increase the voltage of your power source, you will need a step-up transformer.
  • Capacitors: for efficient storage and release of electrical energy, select capacitors designed for use with high voltage.
  • Copper wires, preferably insulated ones, to make the connections and complete the circuit.
  • Connectors and switches: Pick reliable connectors and switches to manage electricity and ensure safe connections.
  • Incorporate a resistor to control the amount of current flowing across the circuit for operational security.
  • Insulating and soldering require the use of electrical tape, a soldering iron, and other common household items.

Step 1: Put Security First

First, guarantee that your workplace is risk-free by eliminating any potential dangers. Protect yourself on the job site by donning safety equipment including gloves and glasses.

Step 2: Circuit Assembling

Please refer to the schematics we have included. First, ensure proper polarity when connecting the power source to the step-up transformer. To prevent a short circuit, solder or use connectors on insulated copper wires.

Step 3: Adding Capacitors and Resistors

Incorporate the capacitors into the circuit in the right way by wiring them in parallel. The power to generate the electric field comes from electrical energy stored in capacitors. Add a resistor to the circuit to keep current low and prevent damage.

Step 4: Insulate the Connections

Once you’ve finished wiring the circuit, you can insulate the connections with electrical tape or heat-shrink tubing. This is a necessary precaution to extend the life of your fish shocker machine by eliminating the possibility of electrical shorts.

Step 5: Put the Device Through Its Paces

Make sure your do-it-yourself fish shocker works before heading out into the field. Verify the integrity of the circuit by checking its components and making sure all connections are tight. Avoid mishaps by being cautious and following safety procedures during testing.

Section 4: Precautions and Safety Measures

Safety should be your number one concern while you build and use your fish shocker machine. Some safety measures to take into account are as follows.

  1. Keep away from electrical lines and bad weather when using the fish shocker equipment.
  2. If there are any endangered or protected species in the water, you should not use the machine.
  3. When going electrofishing, make sure you have the proper permissions and always respect local laws.
  4. Keep away from the water while using the equipment.
  5. It’s dangerous to use the fish shocker machine by yourself. Have someone else there to help and watch your back for safety’s sake.


Congratulations! You have created a fish shocker machine in the comfort of your own home. By adhering to these instructions,
