The importance of dissolved oxygen in aquaculture
Among many water quality indicators, dissolved oxygen always runs through the whole process of aquaculture, which is a very important factor in the success of breeding, and is a decisive factor in the occurrence of diseases. The most feared thing in aquaculture is lack of oxygen, which produces excessive harmful bacteria, ammonia nitrogen, nitrite, and hydrogen sulfide, causing slow growth, death, and even outbreaks of fish and shrimp. At the same time, dissolved oxygen also directly affects the therapeutic effects of diseases in farmed animals, as well as a series of problems such as dosage. So it is not too much to think of dissolved oxygen as the soul of aquaculture! Mastering the changing law of dissolved oxygen can greatly reduce the risk of breeding and increase the success rate of breeding. Like people, aquatic animals must survive under aerobic conditions. Hypoxia can cause them to float, and in severe cases, the pan-pools die. Generally speaking, the dissolved oxygen in the culture (bred) water should be kept at 5-8mg / L, at least should be kept above 4 mg / L. Dissolved oxygen in ponds is mainly caused by photosynthesis of phytoplankton, mechanical aeration and the dissolution of oxygen in the air into the water. The consumption of dissolved oxygen is mainly the respiration of plankton and the decomposition of organic matter in water. In addition, dissolved oxygen in ponds is also affected by various factors such as light, wind, air pressure, plankton, and water quality. Since dissolved oxygen is invisible, it is difficult to grasp whether or not oxygen is lacking. The best way is to use a dissolved oxygen meter to monitor. An Lai Li Si is now launching two professional dissolved oxygen meters, desktop and portable. The models are DO410 and DO300 respectively. The operation is simple, easy to use and accurate. I hope to contribute to our aquaculture industry. The power of people!
