Abstract
Longnose dace and blacknose dace were collected from the Waccabuc River in Westchester County, N.Y. Stomach content analysis revealed that the diets of the two species were similar and dominated by hydropsychid larvae. Overlap calculations showed there was greater similarity in diet between the two species where they were found together than between different collections of the same species, indicating that diet was more a function of when and/or where specimens were collected than of species identity.This publication has 3 references indexed in Scilit:
