大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数): 0; 背的软条 (总数): 15-16; 臀棘 0; 臀鳍软条: 12 - 23. Belly sharply keeled. No distinct silver stripe along the flank and the first (anterior) supra-maxilla minute or absent (cf. Platanichthys platana). Distinguished from very similar R. arcuata of coastal waters by having fewer dorsal and pectoral fin rays and fewer gill rakers total; from small Sardinella and Harengula by the evenly rounded hind margin of the gill opening.
腹面锐利地龙骨。 没有明显的银色斑纹沿着侧面与第一个 (前面的) 上颚骨细小或不存在 (比较 孔头鲱［Platanichthys platana］ ). 与沿岸水域的非常相似 R. arcuata 藉着具有区分了比较少的背部与胸鳍鳍条与较少的鳃耙总数; 从小的 沙丁鱼 与 Harengula 藉由均匀地圆的鳃裂的后缘。
Apparently confined to freshwater at mouths of rivers and their lower reaches. Presumably schooling.
显然局限于淡水在河口与他们的下游。 推测为群游。
