摘要：
The present invention relates to an oxygen supplying system of a shellfish farm which includes a dissolved oxygen concentration detecting unit which detects the dissolved oxygen concentration of water stored inside a water tank farming shellfish； an oxygen supplying device supplying oxygen inside the water tank according to control signals； and a control unit which controls the on/off operation of the oxygen supplying device according to the detection information of the dissolved oxygen concentration outputted by the dissolved oxygen detecting unit. The dissolved oxygen concentration detecting unit includes a housing unit which is inserted into the inside of the water tank； a temperature sensor which is installed on the housing unit and which detects the temperature of water inside the water tank； an optical sensor film body which is installed on the housing unit to be in contact with the water inside the water tank and which varies the intensity of fluorescence emitted by being reacted to lights incident according to the concentration of the oxygen and excited； a light source unit which is installed inside the housing unit and which emits lights toward the optical sensor film body； a light detecting unit which is installed inside the housing unit and which detects the fluorescence emitted from the optical sensor film body and outputs electrical signals corresponded to the detected fluorescence； and a dissolved oxygen measuring unit which calculates the dissolved oxygen concentration inside the water tank based on the temperature information detected by the temperature sensor and the electrical signals outputted by the light detecting unit and outputs the calculated dissolved oxygen concentration information to the control unit. According to the oxygen supplying system of a shellfish farm as described above, the accuracy of measuring the dissolved oxygen concentration can be improved so that oxygen supply to the inside of the water tank is efficiently controlled.
