Low-Emission Factory Shrimp Farming System

Abstract

The invention discloses a low-emission industrialized shrimp culture system. The system includes a culture pond, a microfilter buffer tank, a microfilter and a dissolved oxygen container, and the culture pond is connected to a water inlet pipe; the microfilter buffer pond is provided with an overflow port, and the overflow port is connected to the main discharge pipe through a water exchange pipe; The microfilter is installed above the microfilter, and the microfilter is connected to the bottom of the culture pond through a main pipe, and the water outlet of the microfilter is connected to the buffer tank of the microfilter; the top of the dissolved oxygen container is provided with a jet, and the jet is The main pipeline communicates with the second water inlet pump to communicate with the buffer tank of the microfilter, and the bypass of the ejector communicates with an oxygen intake pipe to mix oxygen into the water; the dissolved oxygen container communicates with the culture tank near the top through a loop water pipe. The low-emission industrialized prawn culture system of the present invention adopts a small water body circulation system, on the basis of ensuring the water quality of the culture water body, reduces the water demand of the whole culture system, reduces the operating cost of the system and the overall equipment investment in the culture process, and Can meet high-density farming.

Description

technical field [0001] The invention relates to the field of culture technology, in particular to a low-emission industrialized shrimp culture system. Background technique [0002] China is the largest shrimp farming country in the world, with a farming area of ​​more than 4 million mu. The average annual shrimp consumption in China is 2 million tons. Around 2013, China changed from a shrimp exporter to a shrimp importer. It is estimated that the shrimp import will exceed 1 million tons in 2017, and the overall demand for shrimp is strong. [0003] There are currently several modes of shrimp farming: [0004] Earthen pond farming, the most traditional shrimp farming model, directly uses external seawater. During the breeding process, the water is not changed or is rarely changed. The breeding pond is equipped with water truck oxygenation equipment. The soil pond farming mode cannot be controlled during the breeding process, and it is completely dependent on the weather. Th...

Problems solved by technology

Shrimp industrialized farming includes two forms of industrialized flowing water aquaculture and industrialized full-circulation aquaculture. Industrialized flowing water aquaculture ensures the clean water in the system, but consumes a lot of water resources and the aquaculture wastewater has not been treated; industrialized full-circulation Aquaculture, although the consumption of water resources is small, but a large number of various equipment are used in the aquaculture system, which consumes a lot of energy and costs, and is not easy to promote

At present, there are two main problems in this mode: First, the current so-called factory farming mode comes from the abalone and sea cucumber farming mode in northern my country. After years of development, it still has not completely broken away from the basic concept of cement pool + greenhouse

Second, full-cycle aquaculture has been proven in practice. The overall cost of a complete set of equipment is high, and the initial investment in equipment is huge; the energy consumption of equipment operation is huge, and the cost of breeding is more than double the cost of traditional farming; there is basically no water change during the entire growing cycle , there are many problems such as ion imbalance in the aquaculture water body, and various supplementary reagents need to be put in, but it is still difficult to achieve the effect of natural seawater, which affects the growth of prawns; practice shows that the current full-circulation aquaculture model has low economic indicators and does not have large-scale Possibility of popularization and application. The factory-like full-circulation aquaculture farms currently in operation mainly focus on demonstration breeding and leisure tourism.
