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

[0017] Example 1 Construction of stacked fish and shrimp circulating water polyculture system

[0018] (1) Construct culture pond I1, culture pond II3, culture pond III5, and culture pond IV6. First build the breeding pond IV6, which can be built as an above-ground or semi-underground type, which is a steel-concrete structure; then, build up the cultivation pond III5, the cultivation pond II3, the cultivation pond I1, the cultivation pond III5, the cultivation pond II3, and the cultivation pond Ⅰ1 is a steel plate structure, and its vertical distribution is supported by a steel structure frame.

[0019] (2) Construct sedimentation tank I8, purification tank I10, clear water tank I11, sedimentation tank II17, purification tank II26 and clear water tank II23, all of which are steel concrete structures; The elevation of the top of II26 is 0.5 meters lower than the top of sedimentation tank II17, and the water inlet at the top of purification tank II26 is connected to the outlet ...

Abstract

The invention discloses a layered fish and shrimp circulating water polyculture system. The system is composed of a culture pond I (1), a culture pond II (3), a culture pond III (5), a culture pond IV (6), a settling pond I (8), a purifying pond I (10), a clear water pond I (11), a settling pond II (17), a purifying pond II (26) and a clear water pond II (23), wherein the culture pond I (1), the culture pond II (3), the culture pond III (5), the settling pond II (17), the purifying pond II (26) and the clear water pond II (23) are connected in series to form a penaeus monodon culture system, and the culture pond IV (6), the settling pond I (8), the purifying pond I (10) and the clear water pond I (11) are connected in series to form a tilapia mossambica culture system. The system mainly has the advantages that high-density culture of penaeus monodon is achieved; water purifying capacity is high, and drainage rate is low; synchronous culture of penaeus monodon and carnivorous fishes is achieved; separate control of fish and shrimp circulating water can be conducted easily.

Description

technical field [0001] The patent of the invention belongs to the technical field of aquaculture and water environment protection, 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 areas where land resources are tight. 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 aquacu...
