Albacore

Albacore (Thunnus alalunga) are streamlined tuna with a deeply forked tail and exceptionally long pectoral fins; in fish about 50 cm and longer, the pectorals are roughly 30% of fork length or more. The body is covered with very small scales.

Streamlined fusiform tuna with very long pectoral fins, a deeply forked/lunate tail, small finlets behind the dorsal and anal fins, and very small body scales.

FishBase lists a common length of about 100 cm fork length (39 in).

FishBase lists a maximum published length of 140 cm fork length (55 in) and maximum published weight of 60.3 kg (about 133 lb).

Feeds on fishes, crustaceans and squids.

Highly migratory schooling tuna; concentrations can occur along thermal discontinuities and around prey or floating objects.

Puerto Rico occurrence is documented. Albacore are highly migratory open-ocean tuna; offshore temperature/current boundaries, bait concentrations and floating structure are useful search zones rather than guarantees of fish.

Marine, pelagic-oceanic tuna using epipelagic and mesopelagic open water. Juveniles favor warmer surface water; larger fish commonly use cooler, deeper water.

Published species depth range: 0–600 m (0–1,969 ft). This is occurrence depth, not a recommended trolling depth.

The species occurs from the surface to 600 m. Fish the depth where bait, temperature/current structure and sonar marks are active rather than assuming one fixed depth.

Marine, pelagic-oceanic open water; epipelagic to mesopelagic habitat.

Fish when local reports show bait and pelagic activity; in Puerto Rico these fisheries can be productive in multiple seasons rather than one universal peak.

Dawn through mid-morning and late afternoon are common starting windows, but active bait and current can produce throughout the day.

Offshore current edges, rips and convergences usually matter more than the tide table alone; fish the side holding bait.

Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.

Common starting baits are ballyhoo, sardines, flying fish, squid strips or other locally abundant forage matched to size.

Trolling heads, feathers, plugs, spoons and metal jigs are common; match lure size and color to local forage.

Start with a medium-heavy offshore outfit, 30–50 lb main line, 50–80 lb leader and a bait/lure matched to the forage; scale up for larger fish.

A practical starting range is roughly 5/0–9/0 for natural bait, scaled to bait size and the target; use strong, non-stainless hooks when release is likely.

30–80 lb class mono or braid is a common offshore starting range; scale heavier for large tuna or billfish and lighter for school-size fish.

40–100 lb mono/fluorocarbon is a common starting range; toothy species may need heavier abrasion-resistant or wire bite protection.

Troll, live-bait, cast to visible feeding fish or vertical-jig marked fish; prioritize bait concentrations and current edges.

Let it go quickly if you're not keeping it.

Albacore has documented food use in the BigJoe catalog/source set. Freshness matters — keep it on ice, and watch for any toxin or mercury advisory.

Widely marketed as food. Chill immediately because tuna can form histamine/scombrotoxin if temperature control fails.

Safety first: FOOD STORAGE HAZARD — if this fish is not promptly and properly chilled after catch, histamine/scombrotoxin can form. Cooking, freezing or smoking does not reliably destroy the toxin once formed. Ice it right away. Use a clean board and sharp knife; scale or skin only when appropriate, remove the viscera or fillet cleanly, trim damaged tissue/bloodline as desired, minimize warm-water exposure, and keep the edible portion cold. If the fish carries venomous spines, dangerous teeth or a toxin advisory, follow the safety warning before cleaning.

For routine cooked preparation, FDA seafood guidance uses 145°F (63°C) as the safe internal-temperature target for fish; flesh should be opaque and separate easily with a fork. Grilling, baking, broiling, steaming or pan-cooking can all work after the fish is positively identified, legally retained and cleared for applicable toxin/mercury advisories.

Rules: Current NOAA Atlantic HMS recreational rule: fishery open; no federal minimum size and no federal recreational bag limit for albacore. An HMS Angling or HMS Charter/Headboat permit is required to fish recreationally for Atlantic albacore.

Avoid needless kills and follow protected-species, area and season rules.
