Two diets were compared for the cladoceran, Ceriodaphnia reticulata for use in culturing and life-cycle toxicity tests. One diet is a suspension of dry yeast dissolved in distilled water and fed at a rate of 250 microgram per animal. The other diet is prepared from frozen adult brine shrimp and distilled water. The aged supernatant is fed using 0.05 mls per animal. The young production per female of surviving adults is comparable but the longevity of the animals fed the yeast diet was considerably greater than the animals fed the shrimp diet.
