Fishing Tips for Yunnanilus niulanensis
- Use ultra‑light tackle; a 4‑6 inch ultralight spinning rod works best.
- Fish with a 2‑4 lb test line and small split‑shot weights to keep the presentation near the bottom.
- Bait with live micro‑invertebrates such as daphnia, mosquito larvae, or tiny chopped worms.
- Cast or drift slowly over gravel beds and retrieve gently; a slow, subtle jigging motion often provokes a bite.
