Distribution of the bivalve resorves in Deukryang Bay was investigated in May, August and November, 1995 and February, 1996. Seasonal sampling was carred out from 29 stations in Deukryang Bay. The bivalve resouces in the bay consisted of 10 species nd mean density in individuals and biomass was 3 inds./$m^2$ and 211g/$m^2$ in May, 3 inds./$m^2$ and 185g/$m^2$ in August, 2 inds./$m^2$ and 379g/$m^2$ in November, 2 inds./$m^2$ and 305g/$m^2$ in February. The dominant bivalve species in Deukryang Bay was pen shell (Atrina pectinata) through the year. Species composition and abundance of the bivalve resources were closely related to station. The stock density was high at inner stations in the bay. G1 station showed the highest density among 29 stations.
