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).
More on author: Rafinesque.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 0°C - 31°C (Ref. 35682); 64°N - 30°N
North America: widely distributed throughout Canada and south to Virginia and Texas, USA.
Length at first maturity / Size / Weight / Age
Maturity: Lm 4.2  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 5723); common length : 8.6 cm TL male/unsexed; (Ref. 12193); max. reported age: 4 years (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).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00227 - 0.00879), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (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.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tm=1; K=0.87; tmax=4; Fec=2,990).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (15 of 100).
