Abstract

Gamō Lagoon, which is well known as a resting and feeding place of migratory birds such as waders, snipes and plovers, is subjected to human impacts such as urbanization, construc tion of harbour, industrialization and fish culture. With the aim of the conservation of the ecosystem, an ecological survey was undertaken. The present survey revealed a large accumulation of organic polutants along the bottom of the interior region due to the lack of proper water exchange with the sea water, which may be a factor to lead the extinction of the benthic fauna. Though the water exchange in this region can be increased by a connection of the lagoon to the open sea, it may also have an undesirable effect on the available fauna due to an increase of salinity of lagoon water and a lack of organic substances in the tidal flat.
