Indo-West Pacific: in warm waters including oceanic islands and archipelagos. A few stray specimens have been collected in the Eastern Central Pacific. Highly migratory.
印度-西太平洋: 在溫暖的水域包括大洋性島嶼與群島中。 一些迷途的標本曾經在中太平洋東部收集。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139)
Length at first maturity / 大小 / 重量 / 年齡
成熟度: Lm 42.3, range 40 - 65 cm
Max length : 100.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 168); common length : 60.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 168); 最大體重: 14.0 kg (Ref. 30874); 最大年齡: 6 年 (Ref. 121508)
背棘 (總數) : 10 - 15; 背的軟條 (總數) : 11 - 15; 臀棘: 0; 臀鰭軟條: 11 - 15; 脊椎骨: 39. This species is distinguished by the following characters: medium-sized fish with a robust, elongate and fusiform body; teeth small and conical, in a single series; total gill rakers on first gill arch 29-34; D1 XI-XIV with both dorsal fins separated by only a narrow interspace (not wider than eye), anterior spines of first fin much higher than those midway, giving fin a strongly concave outline; D2 much lower than first and followed by 8-10 finlets; anal fin followed by 6-8 finlets; pectoral fins short, never reaching interspace between dorsal fins; 2 flaps (interpelvic process) between pelvic fins; very slender caudal peduncle with a prominent lateral keel between 2 small keels at base of caudal fin; body naked except for corselet and lateral line. Colour of back dark blue with a complicated striped pattern which does not extend forward beyond middle of first dorsal fin; lower sides and belly silvery white; several characteristic dark spots between pelvic and pectoral fins (but may not always be present) (Ref. 9684, 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
泳鰾不存在。 椎骨突起的沒有痕跡。 第一背鰭的前面棘比那些中間者高許多。 腹鰭間的突起小而兩裂的。 身體裸露的除了甲胄與側線。 背部的在後部部分具有一個斷掉斜的斑紋的圖案。
Occurs in open waters but always remains close to the shoreline. The young may enter bays and harbors. Forms multi-species schools by size with other scombrid species comprising from 100 to over 5,000 individuals. A highly opportunistic predator feeding indiscriminately on small fishes, especially on clupeoids and atherinids; also on squids, crustaceans and zooplankton. Caught in multispecies fisheries, mainly by surface trolling; also with gill nets. Generally marketed canned and frozen; also utilized dried, salted, smoked and fresh (Ref. 9684).
出現於開放的水域但是總是逗留在接近海岸線。 幼魚可能進入海灣與港灣。 形成多魚種的依大小形成魚群從 100 到超過 5,000個個體包含的與其它的鯖魚種在一起。 不加選擇地捕食小魚的一個高度隨機的掠食者, 尤其吃鯡魚與銀漢魚; 也吃烏賊，甲殼動物與浮游動物.(參考文獻 9684) 通常在市場上銷售罐裝及冷凍; 也利用乾燥的﹐鹽醃的, 煙燻 (參考文獻 9684) 與生鮮地.(參考文獻 9987)
