Etymology: Tenualosa: Latin, tenuis = thin + Latin, alausa = a fish cited by Ausonius and Latin, halec = pickle, dealing with the Greek word hals = salt; it is also the old Saxon name for shad = "alli" ; 1591 (Ref. 45335).

生态学
海洋; 淡水; 半咸淡水; 溯河洄游 (Ref. 51243); 深度上下限 0 - 50 m (Ref. 188). 熱帶; 31°N - 5°N, 95°E - 123°E (Ref. 188)
Northwest Pacific: China and possibly southward into South China Sea, but records uncertain. Eastern Indian Ocean: two specimens collected from Phuket Island, Andaman Sea. The species thus overlaps Tenualosa toli in range.
西北太平洋: 中國與可能在南方的進入南中國海之內, 但是記錄不確定的。 東印度洋: 二件標本採集自安達曼海的普吉島了。 此魚種在範圍中與. 托氏鰣〔Tenualosa toli〕 部分重疊。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 47.5, range 44 - 51 cm
Max length : 61.6 cm TL 雄鱼/尚未辨别雌雄; (Ref. 45563); common length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 27773); 最大体重: 5.0 kg (Ref. 47439); 最大年龄: 8 年 (Ref. 45563)
背棘 (总数): 3; 背的软条 (总数): 14-15; 臀棘 2; 臀鳍软条: 16 - 18; 脊椎骨: 44 - 45. Belly with 29 to 34 scutes. Head large; a median notch in upper jaw, which distinguishes it from other similar clupeids, except Hilsa kelee; with a well developed sebaceous eyelids. Gill rakers fine and numerous, each raker with scattered asperities. Caudal fin deeply forked with minute scales. A dark blotch behind gill opening and a series of spots along flank. Color: Metallic blue-green back that lightens to silver along the sides (Ref. 45563).
腹面有 31 到 32个鳞甲。 头部大的; 除了 Hilsa kelee 以外,在上颌中的一个中央的凹槽,可用来与其他的相似鲱鱼区别。 鳃耙细且多, 每个耙有分散的粗暴。 尾鳍中等的。 一个黑色斑块在后鳃裂与一系列的斑点沿着侧面。
Schooling in coastal waters and ascending rivers to breed. Adults are found near the surface at sea while larvae and juveniles spend the first two years of their life in river tide pools and estuaries (Ref. 57990). Feed on planktonic crustaceans like cyclopoids and other copepods, and rotifers (Ref. 45563).
群游于沿岸水域而且溯溪产卵。
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Ascend rivers to breed (Ref. 45563). After spawning, the adults go back to the sea while the larvae stay in river mouths during their first year. At the beginning of their second year, the juveniles swim to the sea (Ref. 45563).西北太平洋: 中國與可能在南方的進入南中國海之內, 但是記錄不確定的。 東印度洋: 二件標本採集自安達曼海的普吉島了。 此魚種在範圍中與. 托氏鰣〔Tenualosa toli〕 部分重疊。
