最近几年,日本养殖珍珠的經营单位、設备和生产量等都有所增加。但是,养殖珍珠主要产地的三重县,却因密养引起珍珠質量的降低和养育期的延长。自1960年以来,向瀨戶內海、四国、九州方面发展的珍珠养殖业正在逐漸增加、又加上其他府县开拓了新养育海区,因此,日本府县的最高产量正从三重县向其他府县轉移。 In recent years, Japan’s cultured pearl business units, equipment and production have increased. However, Mie County, the main producing area for pearl farming, has been affected by the reduction of pearl quality and prolongation of its growing period. Since 1960, pearl aquaculture development to the Seto Inland Sea, Shikoku and Kyushu has been gradually increasing and, together with other prefectures, new sea-raising areas have been opened up. Therefore, the highest output in Japan’s prefectures is shifting from Mie Prefecture to other Prefecture transfer.
