Phytopigment and suspended solid concentrations in bottom seawater with tidal rhythm at estuary of a Manila clam Ruditapes philippinarum farming ground were investigated. Chlorophyll α in the bottom seawater increased at flood and high tide, and decreased at ebb and low tide. Fine particles in the bottom seawater had a high ratio of chlorophyll α and phaeo-pigments. Chlorophyll α in the sediment flux increased from flood to high tide, and decreased from ebb to low tide. Fine particles in the sediment flux had a high ratio of chlorophyll α and phaeo-pigments. These results suggest that phytoplankton and sediment are supplied mainly from offshore to the estuary with the tide during flood to high tide periods. Phytopigment contents in the digestive diverticula of Manila clams increased rapidly from flood to high tide. These results indicate that algal diet of Manila clam may be supplied mostly during the flood to high tide period and Manila clam actively digest algal diets during these periods.
