Zero-emission Fish-shrimp mix-culture system
Technical field
The invention patent belongs to aquaculture and water environment protection technical field, and in particular to Penaeus Vannmei batch production follows
The cultivation of ring water, is particularly suitable for the high density recirculated water industrial aquaculture of hinterland Penaeus Vannmei.
Background technique
Penaeus Vannmei delicious meat processes meat height, and suitable temperature range is wide, can grow at 18-32 DEG C, can be in salinity 1-
It is grown under the conditions of 40 ‰, is a kind of excellent desalination cultivation kind.Penaeus Vannmei growth is fast, and disease resistance is strong, gradually at
For the main cultivation shrimp species in China.
However, with the expansion of culture of Penaeus vannamei scale and the raising of cultivation density, environmental pollution and economic constraints
The problems such as get worse, strongly limit the development of culture fishery.It is a large amount of residual especially during intensive aquaculture
Bait excrement is discharged into breeding water body, accumulates the noxious materials such as ammonia nitrogen rapidly, cultivation water is caused to deteriorate, and is generated potential
Environmental pollution.In a very long time, the most efficient method for solving water quality deterioration is to carry out draining in time to change water, however, only
It is only that the daily water consumption of small-sized or medium-sized aquaculture system just reaches several hundred sides, the every growth 1kg of Penaeus Vannmei, at least
Need the quantity of exchanged water of 20 t.Therefore, by eliminating breeding water body based on the circulating water culture system of different biological treatment modes
Pollutant develops high density industrial aquaculture, accomplish economic benefit and environmental protection synchronize develop simultaneously, it has also become Penaeus Vannmei is feeding
Grow technical problem in the urgent need to address.
