Scientists: Fish Do not Feel Pain At Fished


When viewing the fish hooked and then stretched, sometimes we think of how sick fish. However, that opinion was wrong. Fish do not feel pain while they are hooked and torn mouth.

A study conducted by a team of seven scientists from the University of Wyoming in the United States, have concluded that fish impervious to pain. Why? Because of these aquatic animals do not have the ability to respond to brain pain.


According to the study, the reaction of the fish and looks like a writhing in pain, just a subconscious reaction to fish, not a response to pain.


After investigation, it turns out the fish do not have the sensor receptors as humans. These receptors respond to sensors that impair functioning and sending signals to the brain. In humans, the receptor that create pain.


Denies Previous Studies
The findings contradict previous research, which suggests that allows the creatures nociceptor more reflexive and able to feel pain.


In a previous study, conducted by the University of Edinburgh, on the lips of fish Rainbow trout (species of salmon) injected acid solution. Then there is a change of behavior like brushing up on fish gravel and move with the rocking motion similar to mammalian stress. Then, the reaction was summed up as evidence of pain.However, the latest research found that there is little 'fiber C', which is found in fish species of trout and other fish. Fiber is a type of nociceptor C that causes pain.


Meanwhile, recent research leader, Professor James Rose of the University of Wyoming in the United States, also found that the fish does not contain neocortical brain enough to respond to pain. The neocortex is the part of the brain that functions as a sensor perception, generate motion commands, and the ability to recognize objects outside.


Rose said, the fish may experience fainting or basic instinctive response, but it does not cause conscious or ill feelings. Reaction to the trout, because the fish is more uncomfortable.


"There's a lot of conflict surrounding the issue of whether fish feel pain and can feel the fish. Anglers often stigmatized the sadistic and cruel. This is an unnecessary social conflicts," said Professor Robert Arlinghaus, a team of researchers at the Telegraph.
