Abstract
Recently, the golden mussel Limnoperna fortunei, an alien species, has invaded the Tenryu, Yahagi and Toyo rivers in Central Japan. This has raised concerns about the impact it may have on hydraulic power generation facilities. We investigated the period of occurrence and attachment of its planktonic larvae, and their growth. The purpose was to understand the current status of their distribution and consequently develop control methods. The results indicate a clear correlation between water temperature and the period of occurrence of planktonic larvae and the growth of this species.
