In recent years, scholars at home and abroad have proposed that fisheries have entered the era of ecology, and traditional experience management will gradually give way to ecological management. The combination of fishery and ecology is the inevitable trend of fishery development. We should change or even end the backward situation of fishery production solely managed by administration and experience as soon as possible, and use ecological theories and methods to carry out extensive and in-depth research on the increase and cultivation of freshwater fishery, so as to continuously improve the scientific and production level of fishery. Specifically, the relationship between water quality analysis and freshwater fishery growth and aquaculture is as follows.
Medical sewage refers to the sewage discharged by hospitals (general hospitals, professional hospitals and other types of hospitals) to the natural environment or urban pipelines. In addition to the general domestic sewage, the water quality also contains chemicals, radioactive waste water and pathogens. Therefore, it can only be discharged after treatment, especially the sewage discharged from infectious disease wards such as hepatitis can only be discharged after disinfection and sterilization.
Ammonia nitrogen refers to the nitrogen in the form of free ammonia (NH3) and ammonium ion (NH4 +). The nitrogen content of animal organic matter is generally higher than that of plant organic matter. At the same time, the nitrogen-containing organic matter in human and animal feces is very unstable and easy to decompose into ammonia. Therefore, when the ammonia nitrogen content in water increases, it refers to the combined nitrogen in the form of ammonia or ammonium ion. The following problems should be paid attention to during the determination of ammonia nitrogen in water quality:
