Introduction Along the coast of the Sea of Okhotsk of Hokkaido, there are many lagoons such as the Saroma and Notoro lagoons, which are directly connected to the sea by a waterway. In these lagoons, fish culture is popular and many fishery harbors have been constructed. Of all the lagoons, Saroma Lagoon is especially large and deep enough for scallop and oyster culture, which is very popular there. In 1989 the value of the total catch of scallop and oyster amounted to 3.1 billion yen. Ice sea formed in the northwestern region of the Sea of Okhotsk is carried to the coast of the Sea of Okhotsk in Hokkaido
