Embodiment 1

[0030] An ecological fish and shrimp polyculture method, comprising the following steps:

[0031] S1. Pond site selection, renovation and pond clearing: Select a location with abundant water sources, high terrain, flat and open to carry out pond renovation. The pond renovation is specifically: 8-10m from the outer edge of the pond to the field, excavate an annular ditch , the distance between the bottom of the ditch is 2-3m, the vertical depth of the ditch is 2.4-2.5m, and no field ditch is dug in the middle of the pond; the pond can be several units, and the area of ​​one unit is 30-50 mu; then add anti-escape The anti-escape facility is specifically: adding a 60-mesh mesh of 0.3 to 0.4 m at the ridge, and adding a plastic film of 0.1 to 0.2 m above the mesh; then adding an intake and drainage facility, and the intake and drainage facility is specifically: : Add two layers of filters to the water inlet to remove impurities, choose a 20-mesh net for the inner net and extend 1m...

Abstract

The invention discloses an ecological fish and shrimp polyculture method. The method comprises the following steps of S1, pond site selection, transformation and pond cleaning, S2, aquatic plant planting, S3, shrimp seed putting and feeding management, S4, fry putting and feeding management, S5, water level adjustment and water quality management and S6, fish and shrimp fishing. The three kinds of aquatic plants can serve as bait of fishes and shrimps and are sequentially distributed on the upper portion, the middle portion and the lower portion of the water surface of the pond, so that the fishes and the shrimps can well eat the bait anytime and anywhere, growth of the fishes and the shrimps is greatly promoted, the diversity of biocenosis is enriched through the mixed aquatic plants, and the mixed aquatic plants play a certain role in reducing occurrence of diseases; in addition, the pond water body space is fully utilized, biological diversification is formed, bait is fully utilized, pollution is reduced, the water body tends to be stable, disease transmission is reduced through biological prevention and control, and the culture success rate is increased; good ecological benefits can be brought, and industrial economic development can be promoted.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to an ecological fish and shrimp polyculture method. Background technique [0002] In recent years, the development of China's crayfish industry has accelerated. The breeding area has exceeded 10 million mu, the output has exceeded 1 million tons, and the total economic output value has exceeded 260 billion yuan. Crayfish farming has become one of the main models of ecological circular agriculture development. [0003] The fish and shrimp polyculture technology is a kind of biological prevention and control technology, in which farmers mix fish and shrimp for breeding. When shrimp disease occurs, the fish can eat the dead shrimp, eliminate the source of infection, and cut off the transmission route. The purpose of preventing shrimp disease, thereby promoting the high and stable yield of aquatic products. In recent years, there have been many studies on the polyculture model of ...
