Research Abstract	Population of upper reaches in Isite dam in Rhinogobius LD were confirmed landrocked form. Genetic differentiations were suggested for influence of dividing into parts cause of artificial structure between upper reaches of Ishite populations and Shigenobu populations. Population of just under the dam inhabited the individuals originate from upper dam populations.
