摘要： The invention has the purpose of improving and maintaining the water quality inside bays where fish are cultivated, and achieving a habitat that is amenable for fish and other marine life. The supply of seawater from the open ocean into bays is controlled more by the tides than by the currents, and while oxygen-deficient marine areas occur near the ocean floor, the oxygen content in the seawater near the surface is held comparatively high by the photosynthesis of phytoplankton and dissolution from the atmosphere. Therefore, oxygen-deficient and oxygen-less areas can be easily dissipated and eliminated by stirring the sea floor, especially the water of the bottom layer, by means of a seawater pump. The system comprises a seawater pump 100 provided underwater and an oxygen concentration sensor provided near the sea floor, the system being capable of eliminating oxygen-deficient areas by operating the seawater pump 100 and stirring the water of the bottom layer when the measured oxygen concentration goes below a predetermined value.
