Learn how to fillet a fish step by step with this easy NZDiver guide. From first cut to removing bones and skin, master the techniques to get clean, perfect fillets every time.
🐟 Why Learning to Fillet Matters
6
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.
🧰 What You’ll Need
5
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
8
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
6
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
6
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
7
Lay the fillet skin-side down
Carefully slice under the rib bones
Remove them in one clean section
🧼 Step 5: Skin the Fillet (Optional)
6
Start at the tail end
Hold the skin firmly
Slide the knife between flesh and skin
💡 Keep the blade flat to avoid wasting meat.
✨ Step 6: Final Trim & Clean Up
4
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.
