Abstract
The longnose dace Rhinichthys cataractae (Valenciennes) is a small, elongated, slightly dorsoventrally compressed minnow that possesses the widest distribution of any North American cyprinid. We repeated sampling methods used at three sites by a previous study to support or refute those previous data that suggest that longnose dace may also be herbivorous. Our stable isotope analysis results reported here show the diet of R. cataractae to be highly variable and that plant matter or primary producers in stream ecosystems may be consumed by the species.
