Ecological engineered litopenaeus vannamei breeding facility system

Abstract

The invention relates to an aquaculture system, in particular to a high-density litopenaeus vannamei ecological engineered healthy breading system. An ecological engineered litopenaeus vannamei breeding facility system is characterized in that: a plastic-covered tunnel (5) which takes a metal rod as a bracket and is covered by a plastic film is arranged above a breeding pool (7), a biological cleaning pool (1), and a biochemical treating pool (2); the breeding pool (7) is spaced by water guide walls (6) in parallel arrangement to form an S-shaped annular flow channel; an outlet of the annular flow channel is communicated with inlets of the biological cleaning pool (1) and the biochemical treating pool (2); the biological cleaning pool (1) and the biochemical treating pool (2) can be opened at the same time, so that water can flow through the biological cleaning pool (1) and the biochemical treating pool (2); or one of the two is opened, and the water just flows through one of the two, and the flow rate of the two is adjustable; the outlets of the biological cleaning pool (1) and the biochemical treating pool (2) are communicated with an air-floating purifying device (3); and an outlet of the air-floating purifying device (3) is communicated with an inlet of the annular flow channel of the breeding pool (7) through a flow device (4). The system provides a good environment and a good condition for the litopenaeus vannamei, saves water resource and energy resource, and is also environmentally-friendly.

Description

technical field [0001] The invention relates to an aquaculture system, in particular to a high-density Penaeus vannamei ecologically engineered healthy culture system. Background technique [0002] The current culture of Penaeus vannamei in my country is generally in the form of pond culture. Whether it is traditional pond culture or high-level pond culture, it is necessary to install multiple aeration machines and change water in large quantities to maintain a high culture density. This farming method has the problems of energy consumption, water consumption and serious pollution, which seriously restricts the development of Penaeus vannamei farming industry. According to survey data, in freshwater ponds where Penaeus vannamei is mainly cultured, the annual displacement per unit of shrimp farming is 3.0-4.5 meters. 3 / kg of shrimp, the input amount of nitrogen and phosphorus per hectare is about 600 kg and 250 kg, except that about 27% of nitrogen and about 24% of phospho...

AI Technical Summary

Problems solved by technology

These facility systems have a certain effect on increasing the production of Penaeus vannamei, improving the effect of farming, and reducing the discharge of pollutants from farming, but there are still many problems in the operability of the system and the stability of the farming environment.
