24 <br />fish with stomach contents that contained debris but this may have been <br />the fragmented end product of other macro food items. <br />YOY and Adult N. lutrensis consumed most major invertebrate food items <br />and some plant macrofragments and seston° Red Shiners may have sought <br />active invertebrates, grazed on attached algae, and fed on drifting seston <br />(plankton) and plant fragments. <br />Adult N. stramineus was the dominant macrofragment consumer. The <br />number of macrofragments was low but the pieces were larger than those <br />consumed by other fish. Invertebrate remains comprised a significant <br />portion of the stomach contents. Sand Shiners may have selected larger <br />sized plant and invertebrate food items. <br />YOY and Adult Pimephales consumed seston, macrofragments, and inver- <br />tebrates. Though fish in both size groups consumed large numbers of <br />seston, YOY Pimephales consumed more invertebrates. <br />YOY Ictalurus fed on most major food item categories ranging from <br />small particulates (seston) to larger invertebrates. They consumed <br />significantly more Diptera, Coleoptera, and Hemiptera than other fish. <br />By Strata <br />At Strata IV and V no endangered species were collected. The most <br />abundant fish at Stratum IV, YOY Pimephales, consumed seston and plant <br />macrofragments and at Stratum V, Adult N. lutrensis, consumed primarily <br />invertebrates. <br />At Stratum VI, Adult N. lutrensis consumed 80.20%, 78.62%, and <br />95.02% of the invertebrate remains, Diptera, and Ephemeroptera consumed
