Description: The Rio Grande has been identified as one of the most endangered rivers in the United States by American Rivers. Water impoundment, water extraction, and point-source pollution have likely contributed to the decline of the federally endangered Rio Grande silvery minnow (Hybognathus amarus). The overall goal of this study was to locate, identify, and characterize food resources for H. amarus and the ichthyofauna of the Middle Rio Grande (MRG). After locating possible food resources (chapter 1) A single diatom cell was isolated from a mixed environmental collection and grown in monoculture. Unialgal cultures were used to assess H. amarus diatom preferences and conditioning response (chapter 2). An extended flood-pulse release from Cochiti Reservoir allowed me to investigate food resource usage during a flood event.
