This experiment was carried out to estimate biological water purification by cultured Laminaria japonica influenced upon light intensity, dissolved inorganic nutrients and water temperature. Samples of Laminaria japonica were cultured in coastal fish farms from December, 2000 to July, 2001. Blade length and blade width reached to 160-250 cm and 7-10 cm in enlargement phase from January to April, respectively. Wet weight reached to 100-190 g in substantialization phase from May to June. N, P average contents reached to 4.4 mg N/g dry and 0.74 mg P/g dry on June, respectively. N, P maximum uptake rates in enlargement and substantialization phase were 1.2 mg N/m2/day, 0.23 mg P/m2/day and 2.9 mg N/m2/day, 0.43 mg P/m2/day, respectively. Michaelis-Menten's constants of N, P uptake rates in enlargement and substantialization phase were l8 μg N/l, 3.9 μg P/l and 29, μg N/l, 8.7, μg P/l, respectively. Downward irradiance at the N, P maximum uptake rates in enlargement and substantialization phase were 1, 020 μmol/m2/s and 720 μmol/m2/s, respectively. Uptake rates of N and P at 20°C were 2.0 mg N/m2/day and 0.32 mg P/m2/day, respectively. Water temperature coefficients of N, P uptake rates were 1.071 and 1.062, respectively.
