The relationship between salinity and the algal growth was investigated by algal assay procedure and by field survey in Lake Koyama-ike, Lake Togo-ike and Nakaumi which are located in Tottori prefecture.<br>From the field investigation the following results were obtained. Water bloom of Microcystis spp. and Anabaena spp. were observed at less than 1200mg·l-1 of Cl- concentration and at more than 23°C and 18°C of water temperature, respectively. Red tide of Prorocentrum minimum occured at levels higher than 3500mg·l-1 of Cl- concentration and was observed between 5°C and 27°C.<br>From the flask experiment significant negative correlation was observed between Microcystis aeruginosa or Anabaena affinis growth and Cl- concentration. M. aeruginosa growth was hindered at levels above 2300mg·l-1 of Cl- concentration and Anabaena affinis growth at levels above 2700mg·l-1.<br>The yields for both species were halved at 1500mg·l-1 of Cl- concentration. A good positive correlation was observed between growth of both species and water temperature. Positive correlation was observed between P. minimum growth and Cl- concentration.<br>It seemed that Cl- concentration and water temperature were very important factors to controlling the algal succession. There is a posibility that water bloom and red tide are hindered by controlling the Cl- concentration of brackish lakes.
