Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 103.5, range 97 - 110 cm
Max length : 458 cm TL 雄鱼/尚未辨别雌雄; (Ref. 26340); common length : 200 cm FL 雄鱼/尚未辨别雌雄; (Ref. 168); 最大体重: 684.0 kg (Ref. 26340); 最大年龄: 32 年 (Ref. 5810)
背棘 (总数) : 12 - 14; 背的软条 (总数) : 13 - 15; 臀棘: 0; 臀鳍软条: 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.
一个非常大的种, 深的在第一背鳍基底的中央的附近。 比第一个高的第二个背鳍; 胸鳍非常短, 少于 80% 的头长。 有泳鳔。 下侧与腹面银白色有无色的与列的无色点一起轮流的横切线。 第一背鳍是黄色或蓝色的; 第二个红褐色的; 臀鳍与离鳍暗黄色而且有黑色边缘了; 中央的尾部龙骨脊是黑色的当成鱼时。
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).
大洋性的但是季节性地接近海岸而且能容忍宽范围的温度。 他们鱼群依大小, 有时伴随着巴鲣鱼，黄鳍， bigeye, 纵带鰺等等捕食小的群游性鱼 ( 鱼，针鱼, 鳕鱼) 或在乌贼与红色的螃蟹上。 商业地在日本养殖。 生鲜使用用作生鱼片, 也将.装于罐头 (参考文献 9988) 变成稀有的由于大量的过度捕捞。 (参考文献 35388)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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).
