Embodiment 1

[0018] The construction of embodiment 1 stacked fish and shrimp circulating water polyculture system

[0019] (1) Build the culture pool I (1), culture pool II (3), culture pool III (5), and culture pool IV (6). First build the culture pool IV (6), which can be built as an above-ground or semi-underground type, which is a steel concrete structure; then, build up the culture pool III (5), the culture pool II (3), and the culture pool Ⅰ(1), culture pond Ⅲ(5), culture pond Ⅱ(3), culture pond Ⅰ(1) are steel plate structures, and their vertical distribution is supported by steel structure frames.

[0020] (2) Build sedimentation tank I (8), purification tank I (10), clean water tank I (11), sedimentation tank II (17), purification tank II (26) and clean water tank II (23), all of which are steel concrete Structure; the elevation of the bottom of the sedimentation tank II (17) is the same as the ground elevation of the culture pond IV (6), the elevation of the top of the purificati...

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...
