dc.description.abstract	Changes in consumption of benthic invertebrates by yellow perch, Perca flavescens, in Oneida Lake during 1958-1973 were similar to changes in the bottom fauna of the lake from 1956 to 1974. The burrowing mayfly, Hexagenia limbata, which declined to extinction following severe oxygen depletions, was replaced in the diet by chironomids and amphipods and, to a lesser extent, by isopods and trichopterans. A slight decline in the growth rate of older perch occurred in recent years, which may be related to the disappearance of the mayfly. No obvious change in abundance of perch was evident.	en_US
