Fishing Tips for Antarctic toothfish
- Use heavy‑duty gear with a 80–100 lb test line and a strong, fast‑action rod capable of handling deep‑water runs
- Employ large deep‑diving jigs or spoons tipped with fresh or frozen baitfish such as herring or squid
- Troll or bottom‑fish at depths of 400–1500 m, allowing the lure to sink slowly before a steady retrieve
- Stay patient and be prepared for long fights; the fish can make sudden, powerful runs even at great depths
