The biodiversity in the shallow sand beach is less than that in a reef. However, there are also many benthoses, small arthropod, fish and shellfish in shallow sand beach. Both water quality and subsoil affect the revolution of the bio-community. Yano (1997) proposed ecological blocks that are fit to fish spawn to improve the progeniture environment from the awful environmental change due to stacked armor units. This example reveals that the marine structures do some helps with the coastal ecology and provides with a good education function. A research base is located in the north beach beyond An-ping harbor breakwaters. Beach nourishment began in the September this year and will last until July next year. We have carried out two marine measurements on seawater and organisms in this year. According to the resulting organism recognition, we can choose bivalve that exists more than the other creatures to be the index organism for the beach. Therefore, this investigation is to breed the bivalve in an artificial shallow zone and to know the growth of the bivalve in site. From the instantaneous measurements on water quality and subsoil associated with numerical calculation on wave and current field, the effects of waves and current field on bivalve will be studied in the project. We also inspect the growth of the bivalve in site and compare with that in farm. The results of this project can provide the bivalve breeding in site in an artificial shallow zone.
