Longtail Tuna

Thunnus tonggol · also known as Northern Bluefin, Longies

An inshore tuna that brings blue-water speed within reach of small boats, feeding hard on bait balls close to the coast.

Overview

Longtails patrol headlands, bays and shallow inshore reefs chasing whitebait, hardyheads and small pilchards.

They are notoriously fussy — matching the bait size closely is usually the difference between refusals and hook-ups.

A hooked longtail runs long and deep, testing drag settings and knots on light gear.

Where to find them

  • Surface bust-ups inside 5 km of the coast in summer.
  • Headlands and inshore reef holding bait.
  • Bay entrances with strong tidal flow.

Tackle

  • Rod: 8' spin rated 6–10 kg with a fast taper.
  • Line: 30–50 lb braid with 30–50 lb fluorocarbon leader.
  • Lures: 20–40 g slugs, small stickbaits and soft plastics matched to bait size.

Tips from the water

  • Cast ahead of the school's direction, never into the middle of it.
  • Retrieve at maximum speed — longtails rarely take a slow lure.
  • Bleed, ice and eat fresh; longtail is excellent raw when handled properly.

Regulations

Bag limits apply; recreational-only species in some jurisdictions.
