Field surveys and indoor experiments were conducted to prevent the outbreak of green tide by Ulva pertusa at Osaka Nanko Bird Sanctuary. Reduction of biomass of Ulva pertusa was observed at stations where exposure rate to the air was from 30 to 40%. In addition, the exposure rate of 30 to 40% to the air showed no negative impacts on the benthic microalgae and macro-benthic animals. Laboratory experiments revealed that photosynthesis activity of Ulva pertusa decreased when exposed to air for 4 to 7 hours at 25- 35℃. Salinity decrease from 30 to 25 or 20 psu in accompanied with exposure to the air drastically inhibited the photosynthesis of this species. These results suggest the possibility of controlling a green tide of Ulva pertusa without any damage to benthic microalgae and macro-benthic animals by a combination of ground level and low salinity.
