 note = {application/pdf, Although a diversified supply of fish is now required to support the recent increase in fish demand, fish culture, which is the second largest source of supply for fisheries, is facing a serious eterioration of water quality due to material loading by fish feeding. Establishment of fish feeding culture with least material loading has been tried by recovering the loaded materials with the help of useful organisms in Uranouchi Inlet, Kochi Prefecture, in the present study. Loaded dissolved matter, 62 % of total feed, is expected to beabsorbed directly by phytoplankton, and loaded particulate organic matter, 28 % of total feed, will also be absorbed by phytoplankton in epilimnion during the period of vertical water mixing after decomposition to inorganic nutrients in hypolimnion. Phytoplankton are then fed to a filter feeder, the Japanese littleneckclam, followed by harvesting 3rd year clams over 30 mm in shell length from autumn to the next spring in order to establish a zero-emission type of fish feeding culture by recovering the loaded materials. It isestimated that loaded materials by current fish culture can be removed by maintaining an individual (ind)density of 2nd year or older clam such as about 1,000 ind･m-2.},
