Dispatch Method:

Beware of the sharp teeth of sharks when handling them. The eating qualities of bull sharks less than 120 cm (4 feet) long can be improved by killing them humanely by iki jime or a firm knock to the head before placing them in an ice slurry after bleeding. Bull sharks larger than around 120 cm (4 feet) long should be dispatched with a captive bolt tool or firearm (with appropriate safety precautions).

Fish Description:

  • A robust shark with a stout body and a short, blunt snout. Teeth triangular and dorsal fin broad with a curved tip.
  • Grey, greyish-brown to very dark steel-grey colour above, whitish or yellowish below with dark margins to the pectoral fin and tail.
  • Bull sharks can have bald patches on their upper body between the first and second dorsal fins, due to infection with the monogenean fluke Dermophthirius spp.
  • Females mature at between 10-15 years old and 180-230 cm/6-8 feet long. They can live for at least 32 years, producing litters of one to 13 young.

  • This species is dangerous and responsible for many fatal attacks on humans.

  • Bull sharks occur worldwide throughout tropical and warm temperate waters from estuaries and close inshore to about 150 m (500 feet) depth.
