been a reduction in floodplain habitat, as well as the decline of the native fishes,
notably the razorback sucker. Evidence now suggests that microcrustaceans and other
planktonic organisms may be important foods for the fry and adult razorback suckers
(Marsh 1987, Mazsh and Langhorst 1988, Papoulias and Minckley 1990). If the
densities of microcrustaceans presented here aze reflective of those in historical
riverine habitats it appears that the control of floods has also reduced the total food
resource available for the native fishes.
