electrofishing Answered

can someone post an instructable on how to do electrofishing with just a car battery and a switch and wires, without a samus module or a susan module that you buy off of ebay?


In some of the Asian countries, people use wild indigo plant (Tephrosia purpurea) which contains tephrosin and stuns fish but not harmful to humans. This method is simpler than electrofishing

A 12V battery alone will not stun fish*. You need high voltage (kilovolts, maybe tens of kilovolts), and a pulse in the current to induce the stunning effect.

*Unless you're just going to throw the battery at the fish...
