The bottom sea water suspending sediment and the detoritus on the bed sand was analyzed for phytopigments (chlorophyll-a and pheo-pigments) collected using the core-sampler on 4 different tidal flats, Monzen, Imazu, Heta and Kurokata in 2002, 2003 and 2005. Stocked short necked clam Ruditapes philippinarum from the tidal flats where phytopigments were abundant showed better results in fattnes confficient and survival than those from the poory distributed tidal flats, suggesting the usefulness of the present method to evaluate the food environment for the short necked clam on tidal flats.
