| Research Abstract |
Larvae of Ruditapes philippinarum was revealed to widely spread in Lake Nakaumi and Honjo Area, affected by wind and tidal flow. They supposed to be spread into Honjo Area from Sakai Channel through the opening of Moriyama Dike. Micro-satellite analysis of this species revealed genetic isolation between the populations of Lake Nakaumi and Honjo Area before the opening of Moriyama Dike, while they have been made homogeneous within a year after the opening.
