Fishing Tips for Highfin lizardfish

  • Use a sturdy high‑test line and a strong leader to handle sudden runs at depth.
  • Deploy lures or bait on weighted rigs that can reach 200‑1500 m where the fish reside.
  • Operate at low light periods; the fish are more active when the deep‑sea light fades.
  • Monitor your depth sounder and target the continental slope or seamounts where lizardfish congregate.
