In nature, all oxygen-consuming organisms cannot survive, grow and reproduce without the participation of oxygen. The oxygen content in ordinary air is high and stable, accounting for about 21% of the gas composition of air. Therefore, animals on land rarely suffer from hypoxia, while dissolved oxygen in water is small and unstable. The oxygen content in air is 20 times that in fresh water, and the dissolved oxygen content in seawater is even less. Therefore, the dissolved oxygen content in water becomes a limiting condition for the life activities and growth of aquatic animals, and is also one of the important water quality monitoring parameters that people pay most attention to in the process of aquaculture.
However, in the practice of aquaculture, for a long time, aquaculture farmers generally lack the means and awareness of timely and effective monitoring of dissolved oxygen in water, and lack of understanding of the potential harm of changes in dissolved oxygen in water to aquatic organisms, many farmers worry about the cost of increasing oxygen and water quality monitoring. The phenomenon of no floating head of aquaculture organisms is regarded as the criterion to judge whether dissolved oxygen in water is sufficient or not, and oxygen-increasing measures are taken only after the floating head of aquatic organisms is seen, which actually takes oxygen-increasing as a "life-saving" measure. Some farmers also worry about the impact of water hypoxia on aquaculture organisms. Without considering the actual dissolved oxygen status, the water environment of aquaculture plants will continue to increase oxygen, so that the dissolved oxygen content of water has been in a high concentration state, which will cause harm to aquaculture, lead to unnecessary losses or reduce potential benefits.
With the continuous expansion of aquaculture scale now, especially the coastal and inland lakes near the area, the people engaged in aquaculture industry is increasing, aquaculture factories can be seen everywhere. But now water pollution is also more serious, the water quality situation can not be compared with the past, modern aquaculture can not only rely on artificial, should also rely on advanced Internet of things technology. A dissolved oxygen analyzer can be used to monitor the amount of dissolved oxygen in water.
Benefits of using a dissolved oxygen analyzer:
With the rapid development of Internet of Things technology, intelligent and automated aquaculture has become a development trend of large-scale aquaculture in the future. Use iot wisdom aquaculture technology, through the water quality sensor gathering water quality monitoring data in aquaculture farms, for example through the use of dissolved oxygen analyzer to monitor the content of dissolved oxygen in water, and then back to the control center through the cloud platform, management and guidance in time according to the data model and improvement measures to aquaculture, increase the income of the aquaculture.
