Researchers in a recent study have concluded that fish do not feel pain. According to research by an international team, fish do not even suffer when they are hooked and fighting for their lives, the Daily Mail reported.
Researchers say fish do not have a brain system or enough sensory receptors in the nerve cells to experience suffering.
AdvertisementWhile fish may struggle to get free, the scientists say this does not mean they are in pain, instead, they show 'little effect' from injuries and toxins that would leave humans in agony.
In their experiments, researchers inserted needles into the jaws of rainbow trout.
Jim Rose, the study leader from the University of Wisconsin, said that in spite of large injections of acid or bee venom, that would cause severe pain to a human, the trout showed remarkably little effect.
Fish also resumed normal activity within minutes of surgical procedures, as well as after being caught and released back into the water.
Prof Rose added that it is highly improbable that fish can experience pain.
The study has been published in the journal Fish and Fisheries.
