The relationships between the dominant phytoplankton and the water quality factors were examined at seven stations in Osaka Bay and Harima-nada (1995-1996).<br>Monthly changes of water quality factors in Osaka Bay and Harima-nada showed that DIN (dissolved inorganic nitrogen):DIP (dissolved inorganic phosphorus) and TP (total phosphorus):DIP ratios were high in May and June, while DIN:DIP ratio was low and TN (total nitrogen):DIN ratio was high in August and September.<br>The relationships between the dominant phytoplankton and the water quality factors were considerably variable and complex. <i>Skeletonema costatum, Pseudonitzschia</i> spp., <i>Rhizosolenia fragilissima</i>, and <i>Eucampia zodiacus</i> occurred in waters with high DIN:DIP ratio (>100), <i>Ceratium furca, Noctiluca scintillans, Prorocentrum micans, Leptocylindrus danicus, Gyrodinium spirals, Mesodinium rubrum</i>, and <i>Prorocentrum triestinum</i> did with moderate DIN:DIP ratio, and <i>Gymnodinium mikimotoi, Rhizosolenia setigera, Chaetoceros curvisetum</i>, and <i>C. affinis</i> did with low DIN:DIP ratio (<10). DIN:DIP ratio in waters where dominant phytoplankton occurred increased with increased TN×TP, TN:TP, and TP:DIP ratios, whereas it did not decrease with increased TN:DIN ratio.
