Grazing rates of several abundant zooplankters in
Kaneohe Bay, Hawaii were measured at different concentrations
of natural phytoplankton. The concentration by
volume of suspended particles, as determined with an
electronic particle counter, was used as the estimate of
food concentration. The relationship between grazing rate
per animal and concentration of particulate food conformed
closely to a hyperbolic model widely used to describe an
organism's rate of uptake of food or other needed substrate
as a function of the concentration of the substrate.
Maximum observed grazing rates in the eutrophic south
sector of the bay are near the maximum rates predicted by
the model. The concentrations of particles in other areas
of Kaneohe Bay do not appear to be high enough to permit
grazing rates to approach their maximum levels. There
appears to be no preference by the grazers for particles
of a size other than the size most abundant in the
environment. / Typescript. Bibliography: leaves 23-26.
