Ecology Summary - Notropis atherinoides

Language:

Main Ref.	Scott, W.B. and E.J. Crossman, 1973
Remarks	Inhabits lakes and pools and runs of medium to large rivers (Ref. 1998, 10294), reservoirs, and occasionally enters mouths of smaller creeks (Ref. 10294). Most common in clear water over sand or gravel. Forms schools (Ref. 1998). Moves to the surface at dusk to feed on microcrustaceans, midge larvae, and algae; descends to deeper waters at daybreak (Ref. 1998). Preyed upon by birds (gulls, terns, mergansers, cormorants) and fishes (Ref. 1998).
