Also to know is, what is the most humane way to kill a fish?
Humane killing requires that the fishisstunned (rendered instantaneously insensible) before beingbledout. Fish should remain in water until immediately priortostunning. There are two methods that can be used tostunfish caught by hand: percussive stunning and spiking(alsoknown as pithing or iki-jime).
Fish died in shock because there is a suddenlargechange in water temperature, PH, hardness, etc. when thefishowner put them in the fish tank. Since fisheshave no bodyheat, they are sensitive to sudden changes in watertemperature.Most of the quick deaths of fish are due tothisreason.
