| Outline of Final Research Achievements |
Totally 516 natural bivalve larvae collected from Matsushima Bay were isolated and identified by molecular methods. A multiplex PCR assay has been developed that enables simultaneous detection of seven bivalve larvae species on the basis of differences in the lengths of the PCR products. The gut contents were analyzed to clarify the potential food sources of the adult oyster. Using universal primer and gene cloning, sequences of suspended phytoplankton, such as diatom Thalassiosira spp. and dinoflagellate Scrippsiella trochoidea, were mainly detected with other sequences of Bolidophyceae, sea squirts, red algae, ciliates, and copepoda.
