A step by step guide on how to make a half fillet mackerel bait

1 - Cut the tail of the mackerel off at the root.

2 - Put the knife across the side of the fish just behind the mackerel’s pectoral fin and cut though in a straight line until you feel the bone.

3 - Now angle the knife towards the tail and slice one fillet free of the back bone to leave a whole head and body, minus one fillet.

4 - The hook simply goes through both jaws halfway in front of the eyes.
