Dispatch Method:
Beware of the sharp teeth of all mackerel when handling them, even after they are dead. Shark mackerel fillets can have a "sharky" ammonia-like smell but their eating qualities can be greatly improved if they are killed immediately by iki jime or a firm knock to the head before placing them in an ice slurry after bleeding. A firm knock on the head may be easier to implement to stun the fish first before attempting iki jime.
