Fishing is a beautiful thing. Some cast nets into the water, some sling a fishing rod with a bait attached. But fishing in some states in India is way different (and more brutal?) than anywhere else.
In these states, mostly northeastern, fishes are electrocuted before they are caught.
This battery is used to generate the electricity needed to kill the fish. Reddit
They dip electrified rods into the pool of water where the fishes are. The shock either stuns or kills the fishes and they float up.
Using the same technique, they kill fishes in steady streams. The dead fishes float down the stream where they are collected in a net.
Such a practice is not without risks. It is obvious that immersing electric rods into the water while entering it without safety gear could be fatal.
The problem is that in India, such fishing is done using anything from overhead electrical lines to back-mounted car batteries for generating the current needed to kill the fish.
That current could be strong enough to kill a man, as has been documented by Ajay Balachandran, Krishnan B., and Liza John in their case study
on similar fishing practice in Kerala.
