- Abstract
Little is known about prey use by the orangebelly darter, Etheostoma radiosum, and what is known has been described from relatively large river systems. We examined prey use by orangebelly darters from firstand second-order tributaries in the Lower Mountain Fork River of southeastern Oklahoma. Adult darters (n = 141) were captured from five tributaries in 2015, and stomach contents were examined to determine prey use. Aquatic isopods were the most frequently consumed organism. This differs notably from previous reports that insects, primarily dipterans, were the predominant prey for the species.
