Decapitation.
All higher vertebrates need the brain in order to process painful stimuli.
Freezing is the method of choice for people using fish for experimental purposes...it is the only guaranteed way of killing a fish without dismembering or deforming the fishs tissues. Also, it is the best way to kill them without introducing foreign chemicals to their body which may affects laboratory studies, depending on what you are doing with the animal.
So...freezing isnt the most humane method at all...it is simply the best way to kill a fish that needs to remain intact.
Decapitation is the fastest and most humane way of euthanasia for any higher vertebrate.
