The management of fish species in autumn is the direct means to improve economic benefits. The author thinks that the management technology of fish species in autumn should pay attention to the following work. I. Clear the pond in time. After 23 months of breeding fish, the water quality will generally age, natural food will decrease, harmful substances such as hydrogen sulfide and pathogenic bacteria will increase.
