The Spottedfin sole (Trinectes fonsecensis) is a small, camouflaged flatfish found in coastal marine and brackish waters. It grows up to about 25 cm (9.8 in) and is sought for its mild, flaky flesh rather than sport. Anglers target it using light gear and subtle techniques on sandy or muddy bottoms.

Fishing Tips for Spottedfin sole

  • Fish over soft, flat sand or mud flats during low tide when the fish are closer to shore
  • Use a light ledger or drop‑shot rig with a small hook and a piece of shrimp or sandworm as bait
  • Drift a slow‑moving bait or jig just above the bottom and keep the line tight to feel subtle bites
  • Stay quiet and avoid stirring up sediment, as the sole relies on camouflage to ambush prey
