Dispatch Method:

These fish should be killed humanely by iki jime, or a firm knock to the head, before being placed in an ice slurry after bleeding. Large mulloway can be energetic and therefore hard to handle. A firm knock on the head may be easier to implement to stun the fish first before attempting iki jime.

  • Mulloway are silvery grey above, sometimes with a bluish bronze or coppery sheen, and bright silver along the flanks with reflective areas from the lateral line.
  • Juveniles live in estuaries and grow fast, reaching around 25 cm in the first year, and 45 cm in 2 years.
