Stonefish - Cleaning
The stonefish should be alive. Insert the knife at the point where the head meets the body and cut through the joint.
Blood will pour out, so place it in water immediately to drain the blood.
Lay the fish with its head toward you and insert the knife above the dorsal fin.
Cut as deeply as in the photograph.
Next, turn the fish around so that the tail is toward you. Cut along the other side of the dorsal fin as before.
Pin down the tail end of the dorsal fin with the heel of the blade. Grasp the tail fin with your left hand and pull it away from the dorsal fin.
This enables you to remove the dorsal fin neatly. The dorsal fin contains poison, so grill it before discarding to prevent injury.
The fish should now look like this.
Lay the fish with its head to the right and the ventral side up. Insert the knife at the lower jaw.
Cut off the head at this point.
Cut between the fins.
Cut open the belly.
Remove the innards.
The fish should be divided into sections as shown here.
Remove the gills from the head section.
