Eastern Blacknose Dace in August 2022 by Cole Tiemann · iNaturalist
The blacknose dace prefers swift streams (Traver 1929; Harlan and Speaker 1951; Scarola 1973). Greatest densities of blacknose dace adults occur when surface water velocities are between 15 and 45 em/sec (Gibbons and Gee 1972). The species is common at gradients of 11.4 and 23.3 m/km, but almost entirely absent at 67.2 m/km (Burton and Odum 1945).
