How to determine in real time the level of dissolved oxygen in aquaculture water has always been a problem that plagued farmers. They can only rely on their own experience to determine whether the pond will lack oxygen, fish, shrimp and crabs should be floating heads. When the floating head of aquaculture is not serious, the growth of fish, shrimps and crabs is constrained by the lack of oxygen and is slow or multi-pathological. In the midst of carelessness, flooding occurs, causing great losses.
In order to improve the regulation level of dissolved oxygen in aquaculture water, and effectively enhance the preventive measures against hypoxia, the Pukou District of Nanjing’s aquatic products station is located in the joint village, Houyi Village and Susheng Cooperative, part of the green shrimp main (mixed) ponds, and Tangquan Farm. Some fish ponds are equipped with the "Kodak" brand dissolved oxygen control meter. By presetting the upper and lower limits of dissolved oxygen, the water probe monitors the dissolved oxygen changes in real time, and automatically starts when the dissolved oxygen content falls below the lower limit value. Microporous (impeller) aeration machinery, when the dissolved oxygen is higher than the upper limit, the microporous (impeller) aeration machinery is automatically shut down to ensure that the dissolved oxygen in the aquaculture water is always within a suitable range, thereby further improving the water quality. For the healthy growth of fish, shrimp and crabs to create a good environment.
Through the use of nearly half a month, farmers have gained new experiences in increasing efficiency and income, which means “new handsâ€. The first hand is the variety, technology and model to be updated, and the other is a new breed of aquaculture facilities. After the installation of the dissolved oxygen control device in the pond, the biggest experience of these farmers was their practicality and their sense of sleep.
