Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 103.5, range 97 - 110 cm
Max length : 458 cm TL 雄魚/尚未辨別雌雄; (Ref. 26340); common length : 200 cm FL 雄魚/尚未辨別雌雄; (Ref. 168); 最大體重: 684.0 kg (Ref. 26340); 最大年齡: 32 年 (Ref. 5810)
背棘 (總數) : 12 - 14; 背的軟條 (總數) : 13 - 15; 臀棘: 0; 臀鰭軟條: 13 - 16; 脊椎骨: 39. A very large species, deepest near the middle of the first dorsal fin base. The second dorsal fin higher than the first; the pectoral fins are very short, less than 80% of head length. Swim bladder present. Lower sides and belly silvery white with colorless transverse lines alternated with rows of colorless dots. The first dorsal fin is yellow or bluish; the second reddish-brown; the anal fin and finlets dusky yellow and edged with black; the median caudal keel is black in adults. May be confused with several other tunas, these are typically much smaller and easily distinguished by specific patterns of stripes, bands or dots.
一個非常大的種, 深的在第一背鰭基底的中央的附近。 比第一個高的第二個背鰭; 胸鰭非常短, 少於 80% 的頭長。 有泳鰾。 下側與腹面銀白色有無色的與列的無色點一起輪流的橫切線。 第一背鰭是黃色或藍色的; 第二個紅褐色的; 臀鰭與離鰭暗黃色而且有黑色邊緣了; 中央的尾部龍骨脊是黑色的當成魚時。
Oceanic but seasonally coming close to shore. They school by size, sometimes together with albacore, yellowfin, bigeye, skipjack etc. Visual predators (Ref. 88866) preying on small schooling fishes (anchovies, sauries, hakes) or on squids and red crabs. Live up to 40 years in the western Atlantic (Ref. 88822). Weight up to 900 kg (Ref. 88823). Eggs and larvae are pelagic (Ref. 6769). Juvenile growth is rapid (about 30 cm / year) but slower than in other tuna
and billfish species (Ref. 88867). Adult growth is considerably slower, with about 10 years needed to reach two thirds of maximum length. Become rare because of massive overfishing (Ref. 35388).
大洋性的但是季節性地接近海岸而且能容忍寬範圍的溫度。 他們魚群依大小, 有時伴隨著巴鰹魚，黃鰭， bigeye, 縱帶鰺等等捕食小的群游性魚 (鯷魚，針魚, 鱈魚) 或在烏賊與紅色的螃蟹上。 商業地在日本養殖。 生鮮使用用作生魚片, 也將.裝於罐頭 (參考文獻 9988) 變成稀有的由於大量的過度捕撈。 (參考文獻 35388)
Oviparous batch spawner, with an inter-spawning interval of 1-2 days in the Mediterranean Sea (Ref. 88871). Females larger than 205 cm fork length are estimated to have a mean fecundity of 30-60 and 13-15 million eggs, in the western and eastern Atlantic respectively (Ref. 40805, Ref. 88871). Spawning occurs when sea surface temperatures are between 22.6-27.5 ºC and 22.5-25.5 ºC in the Gulf of Mexico and Mediterranean Sea respectively (88868). Spawning occurs between June and August in the Mediterranean Sea (Ref. 88868). Eggs are released directly to the water column and hatch after 2 days (Ref. 88823). At 24°C, embryo development lasts about 32 hours and larval stages about 30 days. Egg size 1.0 mm, larval length at hatching 2.8 mm.
Spawning grounds are mainly known from the Gulf of Mexico and the Mediterranean Sea, but the presence of mature individuals and larvae far from these areas (e.g. Bahamas and central North Atlantic Ocean) suggest that other spawning grounds may also be utilized (Ref. 88873, Ref. 88874, Ref. 88872). Appears to display homing behaviour with (western-tagged individuals migrating back to specific spawning sites either in the Gulf of Mexico or the Mediterranean Sea) (Ref. 88872, Ref. 88870). Fidelity to natal areas seem to occur once individuals reach maturity, i.e. after returning to either the western or eastern spawning grounds (Ref. 88868).
