Blackfin Tuna

Thunnus atlanticus

Handling & regulations: A federal HMS Angling or Charterboat/Headboat permit is required to retain Atlantic tunas recreationally — see the federal permit link below; check current NOAA HMS bag/size rules before keeping one, since this project did not find a blackfin-specific limit distinct from the general Atlantic tunas permit framework.

Commonly confused with: Yellowfin Tuna. If you're not sure which one you've caught, treat it as the more restricted species and release it until you can confirm.

Identification

Second dorsal and anal fins are not elongated (unlike yellowfin tuna's sickle-shaped ones), Long pectoral fin reaches nearly to the start of the second dorsal fin — bluefin tuna's pectoral fin is noticeably shorter, Bronze stripe along the sides; finlets dark with white edges; grows much smaller than yellowfin or bluefin (commonly under 28 inches)

Typical season
Near the northern edge of this species' typical range in Virginia's offshore Gulf Stream-influenced waters — a documented but less common component of the regional tuna fishery than yellowfin.

NOAA Fisheries has no dedicated Atlantic blackfin tuna species page (confirmed via direct fetch attempts, all 404), so identification features here are sourced from Florida FWC's own species profile rather than a Virginia-specific or federal source — a real, named state wildlife agency, but not this project's usual first choice for a Virginia species. Regional (Virginia) occurrence and season are general knowledge, not individually fact-checked; the federal permit requirement is a well-established fact for all Atlantic HMS tunas, not blackfin-specific confirmation.
