Abstract

The present paper presents the findings of field surveys conducted at Southern Primorye and Sakhalin, far-eastern Russia, and northern Hokkaido, Japan, to supply information of the present situation of saccharinian kelp species in southern Primorye, far-east Russia, and describes geographical size variation of the first- and second-year kelp S. japonica in the Sea of Japan. The study examined the relationship between environment and kelp forest using satellite imagery, and the effects of coastal topography. Appearance and density of major saccharinian kelps in three sampling stations of Vladivostok were influenced by topographical environment (inner, mid, and mouth part of bay), and growth of sea urchins was dependent on the standing crop of these major saccharinian kelps. The mouth part of bays in Vladivostok and Nakhodka commonly faced the open Sea of Japan, so topographical condition was similar, but occurrence of both kelp and sea urchin in these two areas were remarkably different. Growth of first- and second-year kelp individuals showed geographical difference, suggesting that the growth of first year S. japonica was controlled by lower temperature, and inhibited growth of first year kelps may be related to higher growth of second year individuals.
