Description
Summary:A first-order approximation for understanding how members of a fish community allocate available food resources can be achieved through an assessment of the degree of diet similarity found within the community. One method of studying this is to sample a discrete community over a collecting season and to evaluate the degree of diet overlap among the members. The purpose of this study was to examine the diet of concurrently collected fish from a single pool over a collecting season, in order to assess the degree of dietary overlap and similarity, and to evaluate this as a measure of the potential for competition among closely related species. To accomplish this, a section of the Waccabuc River in Westchester County, New York was chosen for the study.
