Abstract.Research buoy fills the air in the water, solar energy has the following objectives 1. To build float fills the air in water, solar 2. To upgrade the quality of the water better. The population is The staff of the establishment of trade and distribution of aquatic animals, the number of 7 instrument used in this study to float in the water, solar energy, air refueling Questionnaires and statistical comparison X "," ̅ S.D. And the results of measurement DO with air Dissolved Oxygen Meter. It was found that the researchers can build a float in the water, solar energy, air refueling And three can be used to improve the water quality of cesspools in the establishment of trade and distribution of aquatic animal among the 3 District District, some flippers Chachoengsao province to offer better quality by experimental DO value measured is 1.8 ppm and after use for a period of 1 months respectively. DO increased 3.5 ppm. Analysis of the data from the questionnaire and satisfaction to use float fills the air in the water, solar energy. Mean of population are satisfied at the highest level, the average 4.32.
