- Abstract
Seasonal changes of seston were monitored in the pearl cultivation area of Uchiumi Bay, Ehime Prefecture, Japan, where the pearl oyster Pinctada fucata martensii is cultivated. The concentrations of chlorophyll a and particulate carbon, nitrogen and phosphorus were measured and the community structure of the phytoplankton investigated. The dominant size fraction during the study period is consumed by oyster larvae, but is too small for the adult pearl oyster. Nitzschia spp. became dominant but is indigestible for the oyster, which was thus subjected to food limitation. The authors suggest monitoring the composition of seston and phytoplankton for evaluation of the food environment of the pearl oyster.
