Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); atherinoides: From the words atherina, meaning silverside; and oides, Greek suffix indicating resemblance (Ref. 10294).

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 4.2 range ? - ? cm
Max length : 13.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5723); common length : 8.6 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 4 年 (Ref. 12193)
Adults inhabit lakes and pools and runs of medium to large rivers. Most common in clear water over sand or gravel. Form schools (Ref. 1998). Move to the surface at dusk to feed on microcrustaceans, midge larvae, and algae; descends to deeper waters at daybreak (Ref. 1998). Are preyed upon by birds (gulls, terns, mergansers, cormorants) and fishes (Ref. 1998). Oviparous (Ref. 205).
栖息于中型到大型河川的湖与水潭与急流。 清澈的水域在沙地或砾石上面常见于。 形成鱼群。 (参考文献 1998) 在薄暮移动到表面觅食小型甲壳类动物，蚊仔鱼与藻类; 在黎明对较深的水域下降。 (参考文献 1998) 被鸟 (鸥，燕鸥，秋沙鸭, 水老鸦) 与鱼捕食了。 (参考文献 1998)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00228 - 0.00799), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 2.8 ±0.29 se; based on food items.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
