Diaphus diademophilus is a small lanternfish of the Myctophidae family, reaching just 4.9 cm in length. It inhabits the open‑ocean mesopelagic zone and performs nightly vertical migrations, making it a curiosity for night‑time light‑tackle anglers rather than a traditional sport fish.

Fishing Tips for Diaphus diademophilus

  • Use a strong headlamp or surface light to attract the lanternfish’s photophores.
  • Troll a line of ultra‑light 0.2 mm (4‑5 lb test) line with a tiny 1/64 oz jig tipped with minced krill or plankton.
  • Keep the retrieve slow (0.5–1 kt) and let the lure drift near the surface after sunset.
  • Handle the fish gently; they are delicate and have minimal fighting ability.
