This study had conducted to research the novel sediment removing machine to reduce the bottom pollution of fish ponds during the farming period. In this experiment, we carried out the comparing of the ponds which working with the sediment removing machine with the control ponds. This experiment were executed at 4 shrimp ponds each was constructed a central concrete platform for drain and placement with a waterwheel for sludge collection. Two of these ponds-A1,A2 were device with sediment removing machine, while the others-B1,B2 were drain as usually. The result showed that the peak period of sludge drainage within 15~60 sec. from beginning, afterward the sludge drainage tended to slight, however applied the sediment removing machine could drain sludge continuously. In addition when the machine worked one circle a week, the average sediment removing rate of central concrete platform of ponds A1,A2 were 94.8 and 82.3% respective, while those of the ponds B1,B2 were 0 and 5% respective. The effect of sludge removing technique had been proved in this study, such as ensuring the sediment removed quickly, keep not only the stable water quality but also to reduce the use of labor.
