Do you know what is the polyculture mode of fish and shrimp in Longyingwei, Lianjiang, Zhanjiang, Guangdong?

In recent years, fish and shrimp polyculture is more common in Lianjiang, Leizhou, Xuwen, Potou, Nansan and Donghai, and the harvest effect is better. Today, the author will introduce the polyculture model to you with the example of boss Sun's shrimp pond farming business model in Longying, Lianjiang.

General situation of farm

Lianjiang Longyingwei Aquaculture Base is dominated by earthen ponds. The farm has corresponding testing instruments and equipment, general feed reprocessing equipment, more reasonable water exchange and sewage treatment system, and the sewage treatment system is under planning. These farms mainly rely on natural seawater, and the salinity of water can be adjusted according to the needs of aquaculture.

The following is the introduction of boss Sun's breeding base.

Boss Sun's shrimp pond culture time has been as long as 1 1 year, and his fish and shrimp polyculture mode started from 20 10, with a total area of 1300 mu and 50 ponds. According to him, in the past two years, the fish and shrimp polyculture model has been more than 90% profitable, 1% is flat, and its survival rate is about 80%. In the past few years, when operating intensive shrimp culture mode, 90% lost money, only 10% made a profit, and its survival rate was only 3%. Therefore, at present, the polyculture mode of fish and shrimp is more favored by farmers.

Daily management of aquaculture

Due to the biological control of fish and shrimp, there are relatively few diseases in polyculture ponds, and daily management is relatively easy. The transfer of water is not maintained by putting live bacteria into an intensive culture pool, but by natural fungi in seawater (the investment in daily management of drugs is very small). Mainly according to the tidal cycle, the monthly water exchange rate is different, with running water in 15 days and running water in 7-8 days, and the water exchange rate depends on the water color. If there is no tidal period to replace it, calcium peroxide and other aeration methods will be used to change it (one aerator is equipped with 1.5 kW and six aerators are equipped with 20 mu).

Attention problem

Pay attention to changing the bottom, poor bottom is easy to get insects. Golden pomfret is easy to produce mucus when the environment is poor, so it is easy to lack oxygen when changing water frequently.

label

Fish and shrimp polyculture model has high success rate, low risk, low investment and stable income. In recent years, the success rate of intensive shrimp ponds is generally less than 20%, and the polyculture model is a good reference. Bian Xiao believes that the polyculture model of Longyingwei is a real business model, which is suitable for large-scale promotion, stable, not profiteering but profitable for a long time, and can change the polyculture density according to the situation without overdrawing resources. The most important thing is that most people can make money in the difficult environment of raising shrimp.
