What to throw for Blackfin Tuna

Best first. The retrieve matters more than the lure, so each one says how to work it.

  • Vertical jig — Dropped and ripped through a marked school — deadly on blackfin.
  • Cigar minnow — Trolled small, or chunked in a slick behind an anchored boat over structure.
  • Ballyhoo — Small skirted ballyhoo in the trolling spread.

Where to find them

Look for bluewater, nearshore reefs.

Blackfin school over nearshore ledges and the break — look for birds and bait marks. A chunk slick or a fast vertical jig through a marked school gets bit. Great on the grill.

Tide and timing

Tide isn't the driver for blackfin tuna — dawn — the topwater and jig bite is best early.

Tackle

Medium-heavy jigging/spinning · 30–50 lb braid · 40–60 lb fluoro leader

Check the regulations

Size and bag limits change by state and by season, and they change more often than any article gets updated. Check your state agency before you keep anything.
