The necessity of water quality monitoring in aquaculture

Most of the aquatic products in the market are farmed, which has led to people paying more and more attention to the growth environment of aquatic products, and in the aquaculture industry, it is also necessary to analyze the water quality on a regular basis. The bad situation leads to the death of aquatic products, and to a certain extent, it also ensures the health of people who eat the products. In order to improve everyone's protection of aquaculture water quality, let's talk about the necessity of aquaculture water quality monitoring. The necessity of aquaculture water quality monitoring Generally, when monitoring water quality in the aquaculture industry, several important indicators need to be analyzed: 1. Water quality PH: When the PH value in the aquaculture water quality is too low, it will cause fish to have breathing difficulties and slow production, etc. However, when the PH exceeds the standard and becomes alkaline, the gill tissue of the fish will be corroded, resulting in respiratory obstruction. In severe cases, the fish will suffocate. The water quality of strong alkali is also one of the main factors that reduce the microbial activity of the water body. 2. Water quality nitrite: nitrite is an intermediate product produced during the process of replacing ammonia with nitrate. It exists in an unstable state. In the case of sufficient oxygen, it can be converted into a substance with low toxicity to fish by microorganisms. nitrate, but it can be converted into highly toxic ammonia nitrogen in the absence of oxygen. Water quality Increased nitrite concentration will lead to reduced fish feeding, dark purple gills, breathing difficulties, slow swimming, and restless state. And when the concentration is too high, it will cause the fish to move weakly, the fish body will be soft, the bottom of the buttocks will turn yellow, and it will cause organ failure. In severe cases, it will lead to large-scale death of fish. 3 Ammonia nitrogen in water quality: Ammonia nitrogen will cause some harm to fish. When the concentration of ammonia nitrogen is in an elevated state, it will have a slight impact on fish, and it is more prone to disease. If the concentration of ammonia nitrogen is too high, it will cause greater damage to fish. Toxic effects can easily lead to fish poisoning. 4. Phosphate in water quality: Generally, phosphate does not cause toxicity to fish. However, in the case of high phosphate, it will lead to a large number of algae in the water body, and it will also indirectly lead to the normal growth of fish. The existence of a large number of algae in the water body will consume a lot of oxygen in the water, which is not good for fish production. Phosphate is better than nitric acid. Compared with salt, it is more conducive to the growth of algae. The main source of phosphorus in water is the leftover feed of fish, so it is necessary to adjust the amount of fish feed according to the phosphate data index. The normal phosphate level is below 0.05mg/L. 5. Dissolved oxygen in water quality: When there is sufficient dissolved oxygen in the water, toxic substances can be produced, and when there is insufficient dissolved oxygen, ammonia and hydrogen sulfide are not easy to decompose and transform, which will easily affect the healthy growth of fish. The above is the introduction of the necessity of aquaculture water quality monitoring. Since aquatic products are indispensable commodities in our normal life, in order to ensure a healthy life, some aquaculture water quality online monitoring systems should be installed as much as possible in the aquaculture industry, which can play a real-time role. Analyze the effect of water quality, and facilitate the staff to take abnormal handling measures in time.
