Uzbekistan


   


Uzbekistan is located in the hinterland of Central Asia, bordering Afghanistan to the south, Kazakhstan to the north and northeast, Kyrgyzstan and Tajikistan to the east and southeast, and Turkmenistan to the west. Fishery is one of the important economic sectors of Uzbekistan. Uzbekistan has about eight states developing fish farming, including the Republic of Karakalpakstan, Bukhara, Surhan, and Samarkand.

This case sharing is about a Uzbekistan customer farming carp. In recent years, Uzbekistan's fish stock situation has undergone tremendous changes. The ecological status of the water body has a greater impact on the number of fish resources, especially the ecological status of the reservoir. The water intake of the reservoir has reached its limit. In the absence of protection facilities, organisms (fish, zooplankton) are also lost with the water. As a result, the growth of fish was slow, and some even died, which caused certain economic losses to Uzbekistan customers. Therefore, the fish resources in Uzbekistan's reservoirs are decreasing every year, and the amount of fish caught in the reservoirs is not very large. Since the fishing industry in Qashqadaria and Surhan River States is based on reservoirs, their catches are not large. The situation of the lake fishing industry is a little better, but if you want to increase the number of fish resources here, you have to take corresponding regeneration and protection measures.


In order to meet the needs of agricultural production, a large amount of water is drawn from some reservoirs, the water level of which has reached the lowest level, and the fish in the reservoirs are facing the threat of a large number of deaths. Taking into account the current status of fishery production in the country, in order to increase the development level of the pond fish farming industry and promote a significant increase in fish production, Uzbeks customers must take the following measures: Carry out water environmental improvement work, increase water biological production and fish production the amount.

In May 2020, customers contacted AVIC through the Internet to learn about the circulating water system equipment. Customers fully understand the characteristics of each equipment and have certain recognition of our company's production technology. After various exchanges, the customer finally reached an agreement with us, and then the production department immediately went into production.

System process flow: The typical process and equipment of the factory circulating water aquaculture system is based on physical filtration combined with biological filtration, which deeply purifies the aquaculture water body, and integrates an automatic water quality monitoring system to monitor and control the quality of the aquaculture water body in real time and can be traced . The system has the advantages of complete process technology, good water treatment effect, stable water quality, comfortable production operation, simple equipment maintenance, low operating cost, and low system investment.


   This is a simple and effective process technology route: the effluent from the fish pond flows into the microfilter pond to remove residual bait and fish manure and other solid suspended matter with a particle diameter greater than 60 microns, which is lifted by a water pump into the biological filter, and on the one hand, small particles are intercepted. Suspended matter, on the other hand, degrades the ammonia nitrogen in the water body, and the purified water flows back to the fish pond by itself. Parallel bypass is used when the water body needs to be sterilized, temperature adjusted or the water body tends to be turbid.

To sterilize and adjust the temperature of the water body. Controlling the living environment of farmed organisms and conducting scientific management to get rid of the constraints of natural resources such as land and water. It is a high-density, high-yield, high-input and high-efficiency breeding method.

2. Characteristics of factory-based circulating aquaculture The essence of factory-based circulating aquaculture is the industrialization of aquaculture production. The production process is controllable and can be farmed across seasons. The products can be marketed in a planned and balanced manner like industrial products. Its characteristics:


One is that the water consumption is small, lower quality water sources can be used, and the requirements for water resources are low;


Second, it occupies less land and has low requirements for land resources;


Third, the breeding density is high, and the unit water consumption is large;


Fourth, it is easy to control the growth environment, fish (and other cultured species) grow fast, and the growth cycle is short;


Fifth, the feed utilization rate is high;


Sixth, the water is recycled and the utilization factor is high;


Seventh, there is less waste water and waste, which can be treated in a centralized manner, and has no pressure or little impact on the environment;


Eighth, it is not affected by the external climate and can achieve year-round production.

Nowadays, customers have been able to operate the circulating aquaculture system stably, and the profits are constantly increasing. Solve the improvement of the customer's water environment and increase the biological output and fish production of the water body.


Customers are now planning large-scale breeding to further expand the scale of breeding. We also hope that the system can bring more benefits to customers and move towards large-scale farming. Thank you for your strong support and trust in AVIC.
