Description

Spiral zero-emission culture of Penaeus vannamei system
Technical field
Patent of the present invention belongs to aquaculture and water environment protection technical field, is specifically related to Penaeus Vannmei batch production and followsRing water cultivates, and is particularly useful for the high density recirculated water industrial aquaculture of hinterland Penaeus Vannmei.
Background technology
Penaeus Vannmei delicious meat, processes meat high, and suitable temperature range is wide, can be 18-32 DEG C of growth, and can be at salinity 1-Under 40 ‰ conditions, growing, is a kind of good desalination cultivation kind. Penaeus Vannmei growth is fast, and resistance against diseases is strong, becomes graduallyFor the main cultivation shrimp species of China.
But, along with the expansion of culture of Penaeus vannamei scale and the raising of cultivation density, environmental pollution and economic constraintsDay by day serious etc. problem, greatly limit the development of culture fishery. Particularly in intensive aquaculture process, residual in a large numberBait ight soil is discharged in breeding water body, and the noxious materials such as ammonia nitrogen are accumulated rapidly, causes cultivation water to worsen, and produces potentialEnvironmental pollution. In a very long time, the effective method that solves water quality deterioration is to carry out in time draining to change water, but, onlyThe water consumption that is only small-sized or medium-sized aquaculture system every day just reaches hundreds of side, the every growth of Penaeus Vannmei 1kg, at leastNeed the quantity of exchanged water of 20t. Therefore, eliminate breeding water body by the circulating water culture system based on difference biological treatment patternPollutant, development high density industrial aquaculture, accomplishes that economic benefit synchronizes and develop simultaneously with environmental protection, has become Penaeus Vannmei fosterGrow technical problem in the urgent need to address.
Summary of the invention
The present invention is directed to the habit of Penaeus Vannmei, the production cycle of Penaeus Vannmei industrial aquaculture, Yi JinanThe product blowdown feature of different phase in penaeus vannamei production process, proposes a kind of spiral zero-emission culture of Penaeus vannamei systemSystem.
