Study: Fish Endure Prolonged Pain During Air Asphyxiation

A new study found that fish feel pain when they are killed using a common method called air asphyxiation.

This method involves taking fish out of water so they can't breathe.

The study showed that fish like rainbow trout experience pain for about 10 minutes during this process.

Animal welfare groups think this is a cruel way to kill fish because it takes a long time for them to stop feeling pain.

The study also found that putting fish in ice can make the pain last longer.

Scientists suggest using a method called electrical stunning, which could make the process less painful for the fish.
