• Primary production of phytoplankton and macrophytes are measured in a eutrophic lagoon, Lake Kyungpo, where 86% of the lake is inhabited by macrophytes. Phytoplankton standing crop was high, 40-130 mgChl/m³, but productivity per unit area was suppressed low by the light deficiency due to high content of inorganic suspended particles. Contribution of phytoplankton and macrophytes to the total annual production was 55% and 45%, respectively. Allochthonous organic input estimated from BOD was 36% of total organic matter supply. Nitrogen seems to be the limiting nutrient for phytoplankton, since nitrate is often depleted in the water column of macrophyte-growing region and N/P ratio is low. Turbulence and the vertical transfer of oxygen and nutrient are strongly suppressed by the dense population of macrophytes and the chemocline of high stability caused by saline bottom water.
