Dispatch Method:

Beware of the sharp gill covers and dorsal spines of estuary cod when handling them. Estuary cod and other rock cods have similar brain locations and all can be very tolerant of air exposure. To maximise their eating qualities they should be killed humanely by iki jime, or a firm knock to the head before placing them in an ice slurry after bleeding.


Fish Description:

  • Juveniles live near snags and other structure in rivers, estuaries, and inshore reefs.
  • Larger specimens move to offshore reefs as they mature to depths of around 100 m.
