Shark/Tuna Hook sizes 1/0-15/0

📏 What the Sizes Mean

• 0–1–2–3…: Smaller freshwater or light inshore hooks

• 1/0, 2/0, 3/0… up to 15/0: Larger saltwater hooks—the higher the "#/0", the bigger and stronger the hook 

🦈 Shark & Tuna Hook Size Guide

🎯 How to Choose the Right Size

1. Match hook to bait: Bigger hooks needed for bigger chunks (menhaden, bonito head, crab…).

2. Match hook to fish size: Use 2/0–4/0 for moderate tunas; move up to 10/0–15/0 for sharks 

3. Hook style matters: Most shark fishing uses wide-gap circle hooks (7/0 to 12/0), depending on species and bait 

🛠️ Choosing the Right Hook for Your Target

• Tuna (smaller species): Circle or J‑hooks in 1/0–6/0

• Tuna (larger): 6/0–12/0 circle or heavy-duty offset hooks

• Big Game (e.g. marlin, large tuna, sharks): Use 12/0–20/0+

• Shark fishing (surf/drift): 7/0–12/0 circle hooks — 9/0 is often ideal for 3–4 ft sharks 

✅ Final Key Points

• The “/0” system means larger hook with bigger number (1/0 < 2/0 < 15/0).

• Start smaller for moderate fish, scale up by bite size and bait.

• Use wide-gap circle hooks for sharks to improve landing and release success
