Fishing Tips for Halimochirurgus alcocki

  • Use light tackle (2‑4 lb test line) and a sensitive ultralight rod to feel the subtle bites.
  • Trolling small soft‑plastic minnows or live shrimp at 2‑4 knots works best over sandy flats.
  • Fish near the edges of sandbars where currents bring zooplankton, attracting the fish.
  • Keep the hook size small (size 8‑10) to match the fish’s mouth and avoid spooking it.
