Fish can not feel pain.

[tangledline]

Fish are cold blooded and cold blooded animals can not feel pain.
If pain was felt would you stop or move in the direction your pulled to relieve the pain?
Or like a carp bolt at full speed and strength against the pressure and increase the pain?
i feel like fish are using the fight and or flight instinct against the pressure of the line or that something is not right with the situation....if you scare carp they take off like they are hooked...
if the fish felt pain it would swim to a point in the water where the hook pressure caused less pain....towards you.
