成熟度: Lm ? range ? - ? cm
Max length : 16.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188); common length : 13.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数) : 0; 背的软条 (总数) : 16 - 19; 臀棘: 0; 臀鳍软条: 16 - 21. Diagnosis: Body moderately deep, belly fairly sharply keeled (Ref. 188). Lower gillrakers 30-40 (Ref. 188). A black or golden spot behind gill opening; upper part of pectoral fin dusky; caudal fin pale yellow with dusky hind margin (Ref. 188). Sardinella rouxi resembles S. maderensis, which has more gillrakers and a grey caudal fin, its tips almost black (Ref. 188). It is distinguished from small S. aurita by having 1 unbranched and 7 branched pelvic fin rays vs. 1 unbranched and 8 branched in S. aurita, and no black spot on hind part of gill cover (Ref. 188).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
腹面相当锐利地龙骨。 (16-19 腹鳍前的,12-14 后) 在鳃裂后面的一个黑色或金的斑点; 胸鳍的上半部暗色的; 尾鳍白黄色的有暗淡的后缘。 与有更多的鳃耙 (70 到 166) 与灰色的尾鳍的小的 S. maderensis 相似, 与顶端几乎黑色的。 有别于 S. aurita 在鳃盖的后部部份上藉着具有 7个腹鳍鳍条而且没有黑色的斑点。
Sardinella rouxi is found in inshore waters and along beaches, forming schools (Ref. 188).
在近岸水域而且沿着海滩形成鱼群接近水表面。 时常捕捉伴随着幼鱼 S. maderensis. 在市场上销售生鲜地了或盐腌的。
