This is the simple electric fish shocker circuit or fish stunner. It helps in catching fish easier. It uses a 12V battery to convert to 220V AC or 110VAC. We use few parts so easy and cheap.
How it works
This circuit converts voltage from 12V battery to AC 220 volts. Both transistors will alternately work ON and OFF. Because the above phase of the transformer has the same phase as below there.
For example, the top transistor conducts current first. Then, the voltage from 12 volts will be sent to the center trap OV to go to the up terminal. It makes the center is positive and up terminal is negative. And other of the 12V terminal is also negative. Then, the negative voltage below the terminal. So, make lead B of all the above transistors is bias current.
When the above transistors stop conduct current. The magnetic field collapses causing a reverse-phase induction center to be negative. The positive terminal is 12 volts.
Next, the positive voltage will flow to R to bias lead B of the below transistor (Q1, Q2). It causes it switches to connect the circuit. And then induction the 12V to the coil of the lower switch like this forever.
How to builds
Look at the circuit diagram above. We use: the 12-0-12 volts, 3A transformer = 1 pcs. (the general power transformer) Then, bring the 2N3055 transistor to screw at the large heat sink.
Next, connect R-470 ohms, C-0.1uF, and Diode-1N4007 as Figure circuit. You may use the universal board and connect the battery to input.
And the output to wires into the prongs to shock the fish.
The current that will flow from the second terminal of the wire determines the cause of the shorting it.
It does not shock me. Because it does not a full circuit. Unless you hold both ends only.
Let the fish cook delicious things from this project.

I love electronics. I have been learning about them through creating simple electronic circuits or small projects. And now I am also having my children do the same. Nevertheless, I hope you found the experiences we shared on this site useful and fulfilling.
Thanks.
diode connected mistake
Hi hakan,
Thanks for your feedbacks.
Hy … I want schematic of 12 to 600 700 for electro fishing please thanks
how to made or rewind that 12-0-12 transformer ..thanks..bsee student me.!
this circuit is funchional
do you have a full circuit for electrofishing .? i have a privat pound with fish … thanks you are the best
where should I connect tne battery
Seems fish got dead at higher frequency.What is the output frequency of this circuit?
Would you build me one and ship it to me? I don’t know how. Would gladly pay all cost.
Hello,
I am an amature to these kind of stuff. Please tell me whether we could use a 12v DC output to stunn fish. I am worried to play with high volts. Pls advice me with a safe current to play with.
when i put 2wires in water ,voltage drop from 300 to zero.
How many turns of primary and secondary windings are used?
I was getting a bit frustrated because there was a output but no input on the schematic. I kept looking for the “12v+” and “12v-“. Then I gave up and started looking at the components. Don’t worry I took an asprin for the headache I got from the smack on the forehead I gave myself when I saw the battery symbol. (DUH!!) To be fair a battery symbol is not “12v+” or “12v-“, and that is Exactly what I was looking for. It never occurred to me to include the battery after watchung so many vids of partial schematics. Though the battery should be marked with a value. I just hope I’m never looking for a cigarette lighter in a forest fire.

Please how do I lean how to find short circuit & more in inverter 1000watt
Thanks for the circuit. everything works fine.
Hi, Lanutemsu
Thanks for your feedback.
Glad with a good project.
How can i make a fish stunner circuit with variable voltage and frequency, with 100 w power
Is it shock proof, how much distance , what is the frequency
hello i need ur reply admin…. can i use 3.3uf capacitor instead of 0.1uf?? what is the function of the capacitor on that circuit???
Hi jayram,
It affects the output frequency and voltage. Capacitor 0.1uF 250V, it is good.
Your Comment Here…
hello guys can i used complementary capacitor for this diagram?
can you share.
for me
thanks
How can increase the out put voltage from 220 v to above
