生态学
海洋 礁区鱼类; 深度上下限 0 - 50 m (Ref. 188). 热带; 17°N - 19°S, 75°E - 179°W (Ref. 188)
Indo-West Pacific: southern coasts of India, perhaps Bay of Bengal, and Indonesia eastward to Fiji. Reported from New Caledonia (Ref. 9070) and Tonga (Ref. 53797).
印度-西太平洋: 印度的南部海岸, 也许孟加拉国湾 , 与印度尼西亚向东至斐济。 记录来自新加勒多尼亚 (参考文献 9070) 与东加了。 (参考文献 53797)

Maturity: Lm ? range ? - ? cm
Max length : 27.6 cm TL 雄鱼/尚未辨别雌雄; (Ref. 126292); common length : 15.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188); 最大体重: 247.00 g (Ref. 126292)
背棘 (总数): 0; 背的软条 (总数): 13-21; 臀棘 0; 臀鳍软条: 12 - 23. Body moderately deep, belly rather rounded, scutes not prominent. Distinguished from A. sirm by the absence of spots along the flank (gold in life, black on preservation) and fewer lower gill rakers. Closely resembles A. leiogaster, which has more lower gill rakers. Round-bodied Sardinella species have i 8 pelvic fin rays and more than 100 lower gill rakers.
身体中等纵深的, 腹面相当圆的, 不突出的鳞甲。 与 A. sirm 区分了藉由缺少斑点沿着侧面 (活着时金色的, 标本黑色的) 与较少的下鳃耙。 非常近似 A. leiogaster, 有更多的下鳃耙。 圆-身体 沙丁鱼 种有 i 8个腹鳍鳍条与超过 100个下鳃耙。
Forms schools in coastal waters. Feeds on copepods, Mysis and other elements in the zooplankton. Used as bait in the tuna fishery.
在沿岸水域中形成鱼群。 吃桡脚类的动物， Mysis 与其他的浮游动物。 在鲔鱼业中当作鱼饵了。
