Ecology Summary - Percina sciera

Language:

Main Ref.	Page, L.M. and P.W. Smith, 1970
Remarks	Inhabit fast gravel runs, sometimes riffles, of creeks and small to medium rivers. Often found near brush (Ref. 5723, 10294). The species was seldom found over bottom materials other than gravel and never found in quiet pools or shallow water. Accumulations of branches and leaves in the gravel of the channel often contained darters, suggesting that these were hiding or resting sites (Ref. 69400). The minnows, Pimephales vigilax, Notropis whipplei and Notropis spilopterus were the most abundant associated species (Ref. 69400). Juveniles feed on midge and blackfly larvae; adults consume caddisfly and mayfly larvae (Ref. 10294).
