Layered fish and shrimp circulating water polyculture system

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...

AI Technical Summary

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.
