Problems solved by technology

[0003] However, with the expansion of Penaeus vannamei aquaculture scale and the improvement of aquaculture density, problems such as environmental pollution and economic constraints are becoming more and more serious, which greatly limits the development of aquaculture industry.
Especially in the intensive aquaculture process, a large amount of residual bait and feces are discharged into the aquaculture water body, causing the rapid accumulation of toxic substances such as ammonia nitrogen, resulting in the deterioration of the aquaculture water quality and potential environmental pollution.

Embodiment 1

[0016] The construction of embodiment 1 phase zero discharge Penaeus vannamei culture system

[0017] (1) The phased zero-discharge Penaeus vannamei culture system can be constructed on a site with a natural slope or on a flat site.

[0018] (2) Determine the construction site of the staged zero-discharge Penaeus vannamei culture system, as well as the elevation of the bottom of the pond and the overflow weir. The elevation of the overflow weir is 2.0 meters to ensure the same mud discharge pressure. The bottom elevations of the front pond (1), middle pond (2) and rear pond (3) are 1.5m, 1.0m and 0.0m in turn, and the depths of the ponds are 0.5m, 1.0m and 2.0m in order to meet the requirements of Penaeus vannamei. Requirements for water depth in different growing seasons; the width of the front pool (1), the middle pool (2) and the back pool (3) are all 5.0 meters, the lengths of the pools are 10.0 meters, 30.0 meters and 70.0 meters in turn, and the area ratio is 1 :3:7, to...

Abstract

The invention discloses a staged zero-emission culturing system for penaeus vannamei boone. The system is composed of a front pond (1), a middle pond (2), a rear pond (3), a purifying trench (8), an electromagnetic valve (5), a settling pond (6), triangular overflow weirs (10), a mud bucket (13), a water storage reservoir (15) and a filtering and disinfecting device (16). The area proportion of the front pond (1) to the middle pond (2) to the rear pond (3) is 1:3:7, the bottom elevation of the overflow weirs (10) of the front pond (1), the middle pond (2) and the rear pond (3) is 2.0 m, the bottom elevation of the front pond (1) is 1.5 m, the bottom elevation of the middle pond (2) is 1.0 m, and the bottom elevation of the rear pond (3) is 0.0 m, the depth of the front pond (1) is 0.5 m, the depth of the middle pond (2) is 1.0 m, the depth of the rear pond (3) is 2.0 m, the width of the front pond (1), the width of the middle pond (2) and the width of the rear pond (3) are all 5.0 m, the length of the front pond (1) is 10.0 m, the length of the middle pond (2) is 30.0 m, and the length of the rear pond (3) is 70.0 m. The staged zero-emission culturing system has the main advantages that high-density different-pond culture of penaeus vannamei boone in different culture stages is achieved, and culture management is easy; a biofloc system can be easily structured, the water purification capability is high, and zero water emission is achieved; the structure is compact, and land is saved.

Description

technical field [0001] The patent of the invention belongs to the technical field of aquaculture and water environment protection, and specifically relates to industrialized circulating aquaculture of Penaeus vannamei, and is especially suitable for industrialized aquaculture of Penaeus vannamei in high-density circulating water in inland areas. Background technique [0002] Penaeus vannamei has delicious meat, high processed meat, and wide temperature range. It can grow at 18-32°C and at a salinity of 1-40‰. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in my country. [0003] However, with the expansion of Penaeus vannamei aquaculture scale and the improvement of aquaculture density, problems such as environmental pollution and economic constraints are becoming more and more serious, which greatly restricts the development of aquaculture industry. Esp...
