Analysis of wind powered aerator on water quality in shrimp farming

Abstract

Aim: This paper presents the analysis of wind powered aerator on water quality in shrimp farming. Methodology: To study the effect of wind powered aeration on water quality parameters, three tanks of 12m x 4m x 1m each were selected. One tank was kept as a control (T1). In the second tank (T2) windmill operated aerator was installed. In third tank (T3) electric powered paddle wheel aerator (1hp) was installed and the aerator was run between 01.00 and 06.00 hours. The water quality parameters such as DO, Temperature and pH were recorded daily. Results: The highest value of DO obtained was 6.21 and 6.25 mg/l with wind powered aerator aqua tank and electric powered aerator tank respectively. The differences in temperature values of the three experimental tanks were not appreciable. The pH values of the experimental tanks were in the range of 7.8 to 8.7. Conclusion: The dissolved oxygen (DO), dawn DO values in the wind powered aerated tank were within the standard limit of shrimp production.
