Zooplankton grazing rates and life history stage densities for secondary
production estimates were determined in three lakes in the Cedar River
watershed, Washington. Eight copepod species, seven cladoceran and nine
rotifer species were identified in the three lakes. No one species of
cladoceran or copepod occurred in all the lakes,...
Grazing rates and density of the crustacean zooplankton were measured
in Findley and Chester Morse Lakes and Lake Sammamish, Washington.
Sample analysis is incomplete at reporting time, thus estimates of
production from examination of life stage biomass changes was not possible.
Maximum density of crustacean zooplankton was about 10/1 in...
