Note: Large halibut are powerful and can injure anglers on a boat. Halibut rules are set by international and state managers. Size limits, bag limits, and seasons for this species change often, so check current state and federal rules before you keep one.

How to identify it

  • Both eyes on the right side of the body.
  • A dark olive-brown to nearly black upper side and a white underside.
  • A diamond-shaped, flat body with a large mouth.
  • A slightly forked, crescent tail.

Often confused with

Baits and lures

  • Herring and salmon heads
  • Octopus and squid
  • Large jigs and leadhead jigs with big plastic trailers

Techniques

  • Drop heavy baits or jigs to the bottom on sandy and gravel areas.
  • Fish tide changes and use enough weight to hold bottom.
  • Use strong gear and a plan for landing a large fish.
  • Be careful with big fish on deck, since they can thrash.

Field notes

Pacific halibut can live for decades and grow very large. Female fish are bigger than males, and managers set strict limits.
