Filleting your own fish is one of the most valuable skills any angler can learn. Done properly, it means:

  • More usable meat from your catch
  • Cleaner, boneless fillets
  • Better eating quality

Whether it’s snapper, kahawai, or tuna, the same basic principles apply.

Before you start, get your setup right.

Essential Tools:

  • Sharp fillet knife (flexible blade is best)
  • Cutting board (non-slip if possible)
  • Fish scaler (optional, depending on species)
  • Cloth or glove (for grip)
  • Bucket for waste

💡 NZDiver Tip:
A razor-sharp knife makes filleting easier, safer, and cleaner.


✂️ Step 1: Make the First Cut

  • Lay the fish flat on its side
  • Insert your knife just behind the gill plate
  • Cut down until you hit the backbone

👉 Don’t cut through the backbone—this is your guide.


🪶 Step 2: Follow the Backbone

  • Turn the blade and run it along the backbone toward the tail
  • Use long, smooth strokes
  • Keep the knife angled slightly downward

🎯 The goal is to stay tight to the bones to maximise meat.


🧴 Step 3: Remove the Fillet

  • Gently lift the fillet as you cut
  • Slice through the rib cage to free it completely

You should now have one clean fillet removed.

👉 Flip the fish and repeat on the other side.


🦴 Step 4: Remove Rib Bones

  • Lay the fillet skin-side down
  • Carefully slice under the rib bones
  • Remove them in one clean section

🧼 Step 5: Skin the Fillet (Optional)

  • Start at the tail end
  • Hold the skin firmly
  • Slide the knife between flesh and skin

💡 Keep the blade flat to avoid wasting meat.

  • Remove any remaining bones (pin bones)
  • Trim off excess fat or bloodline
  • Rinse lightly and pat dry

Your fillets are now ready to cook or store.


❄️ Storage Tips

To keep your fish in top condition:

  • Chill immediately on ice
  • Store in the fridge and eat within 1–2 days
  • Or vacuum seal and freeze

🍽️ Bonus: Best Way to Cook Fresh Fish

Simple is best:

  • Lightly season
  • Pan fry in butter or oil
  • Add lemon and herbs

Fresh, well-prepared fish doesn’t need much else.


🎣 Final Word from NZDiver

Filleting a fish might seem tricky at first, but with a bit of practice, it becomes second nature. Take your time, use a sharp knife, and focus on clean, controlled cuts.

Do it right, and you’ll get the most out of every fish you catch.
