Traditional fish ponds are mostly integral ponds with different volumes formed by field transformation or rough excavation. The breeding methods are mostly mixed with a variety of fish. This kind of breeding technology has many defects: 1. There are many kinds of fish. The situation of competing for survival resources will easily lead to the lack of good aquaculture development of each type of fish; 2. Traditional fish ponds mostly adopt a structure of one water inlet and one water outlet, and the water inlet and water outlet are often set symmetrically, resulting in only one water inlet and one water outlet. Oxygen is abundant at the water inlet, while oxygen is scarce in other places, which is prone to problems such as uneven feeding, uneven and thorough sewage discharge, and poor water quality. In fish ponds, in fact, the external water sources include clear water bodies in the middle and upper layers and turbid water bodies in the middle and lower layers. Different water bodies are suitable for the breeding of different fish. Such undifferentiated use actually results in a lot of waste of resources and Can not get better breeding effect.
