简单描述 检索表 | 型态特徵 | 形态测量图

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 Harengula 藉由均匀地圆的鳃裂的后缘。

生物学特性     字汇 (例如 epibenthic)

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。

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00349 - 0.01438), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.1   ±0.1 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
