Ecology Summary - Etheostoma maydeni

Language:

Main Ref.	Powers, S.L., B.R. Kuhajda and S.E. Ahlbrand, 2012
Remarks	The ecology of E. maydeni was described by Shepard & Burr (1984) along with the rest of the E. cinereum complex. Cumberland River system populations (i.e., E. maydeni) were noted as having slower growth than other populations, males outnumbering females rather than the opposite for other populations, and a greater reliance on burrowing mayflies (Ephemeroptera: Ephemera) and oligochaetes in their diet with a lower proportion of Chironomidae compared to other populations. Specimens for this study were collected largely in water approximately 0.5–1 m deep over large rocks and course woody debris with slow current adjacent to faster current.
