Background
With the development of aquaculture, water quality problems are increasingly prominent. The problems of aquatic diseases and aquatic quality caused by water quality are increasing. The cause of deterioration of water quality is mainly: (1) improper disinfection results in contaminated water quality; (2) The water becomes thin due to untimely nutrition supply, the nutrition is lost, and the yield of the aquatic products is reduced; (3) The microbial flora is unbalanced, beneficial microorganisms in water are reduced, and harmful microorganisms are dominant; (4) The water body is overnutrition, so that water body plants and microorganisms are expanded, and the living space of the aquatic products is occupied; (5) The high-temperature storm causes the hypoxia of water, blue algae burst and fish choking death.
Currently, methods for improving or maintaining aquaculture water quality mainly include physical methods, chemical methods and biological methods. Wherein, the physical method comprises proper water injection and water change, thus keeping the water fresh; proper oxygenation is carried out, and the water body is kept rich in dissolved oxygen. The chemical method comprises the steps of regularly applying limestone, adjusting the pH value of the water body, and keeping good pH; the water disinfectant is applied regularly.
