Overview
The surveys have been proceeding to clear the status of fishery resources and environmental conditions in the Natori River estuary and support the construction for the fishery. 1. Monitoring of physical environments (Salinity, Temperature, Depth and Bottom sediments) 2. The survey on the Manila clam population status (population density , size composition) 3. The survey on the Brackish water clam population status (population density , size composition) 4. The survey on the Ayu population status.
