Abstract
The invention provides a low-temperature multistage circulating water temporary culturing method of crayfishes, and relates to the technical field of aquaculture. The method comprises the steps that the circulation rate is calculated; the crayfishes are put in a seafood temporary culturing barrel; coarse precipitation is conducted through a vertical flow precipitator; a water body is transported through a water pump; microparticles are removed through a sand filter tank; toxic and harmful organic matter and inorganic salt in the water body are removed through a biological filter; bacteria, toxins, yeast, mould and alga living creatures in the water are killed through an ultraviolet sterilization device; the water temperature is lowered through a water-cooling machine, constant temperature is maintained, and the water temperature is controlled to 2 DEG C; the bottom of the biological filter is subjected to aeration. According to the low-temperature multistage circulating water temporary culturing method of the crayfishes, the environment is improved, physiological changes of living bodies are reduced in the transportation process, the survival rate of the living bodies can be increased in the transportation process, the temporary culturing cycle is long, and the condition that seasonal demands exceed supply can be solved.
Description
Technical field
The present invention relates to technical field of aquaculture, be specifically related to Procambarus clarkii low temperature multistage recirculated water method for temporarily cultivating.
Background technology
The demand of Procambarus clarkii gradually drives the step of China's Procambarus clarkii cultivation, and according to expert opinion, Procambarus clarkii is supported following
Grow value and will exceed several times of other culture fisheries.The present aquaculture model of Procambarus clarkii is in semi-artificial intervention states, and per unit area yield carries
Rise difficulty relatively big, domestic area, basic realize fishing for, short-term storage (1 2 days), bubble chamber automotive on the rocks, wholesale market fast
Disappearing is main supply chain pattern.In view of domestic Procambarus clarkii supply persistently reduces, price increase is too fast, seasonal price is poor greatly, in short-term
Between the problems such as demand is big occur, and Procambarus clarkii is as strategic kind, it is ensured that stable persistently supply significant, foreign resources
Introducing becomes first-selected solution.Africa Procambarus clarkii resource is in state to be developed, and it is excellent to have that price is low, specification matching degree is high etc.
Gesture, but transportation range far becomes short slab.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of improve in live transport survival rate,
Support the cycle temporarily long, it is possible to resolve the Procambarus clarkii low temperature multistage recirculated water method for temporarily cultivating of the seasonal situation that supply falls short of demand.
For achieving the above object, the technical solution used in the present invention is: Procambarus clarkii low temperature multistage recirculated water method for temporarily cultivating, its bag
Containing following steps:
1, cycling rate is calculated；
According to cultivation density, ammonia nitrogen generation amount, sterilizing and the most foster bucket plug-flow link, it is computed, determines system design cycle rate,
Casing need to be overflowed the factors such as loss and takes into account by circulating load；
2, use seafood to support bucket temporarily and place Procambarus clarkii；
Support temporarily every layer of bucket sieve and can place 20kg Procambarus clarkii, water circulation bottom in and top out, bottom blowdown, can fix, logistics transportation；
3, perpendicular stream depositor is used slightly to precipitate；
4, water pump is utilized to transport water body；
5, sandfiltration pot is used to remove microparticle；
Positive backwash operation is controlled, and pressure high filtration capacity is strong, and degree of purification is high, belongs to advanced treating, for filtering 70 μm once
Microparticle；
6, biofilter is used to remove poisonous and hazardous organic matter and inorganic salt in water body；
According to the difference of system, biofilter material filling rate is different, and substantially about 60%, biofilter material selects ∮ 25mm filtrate；Root
According to Procambarus clarkii ammonia excretion amount, nitrogen-removing rate etc. calculates, and determines the volume of biofilter；
7, ultraviolet sterilization apparatus is used to kill antibacterial in water, toxin, yeast, mycete and algae bio；
8, water cooling unit is used to reduce water temperature so that it is to maintain constant temperature, water temperature controlled at 2 DEG C；
9, by aeration bottom biofilter.
What the present invention produced has the beneficial effect that Procambarus clarkii low temperature multistage recirculated water method for temporarily cultivating of the present invention, improves environment,
Reducing live body physiological change in transportation, can improve the survival rate in live transport, it is long that it supports the cycle temporarily, it is possible to resolve season
The joint property situation that supply falls short of demand.
Detailed description of the invention
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below by detailed description of the invention pair
The present invention is further described.
This detailed description of the invention adopts the following technical scheme that Procambarus clarkii low temperature multistage recirculated water method for temporarily cultivating, and it comprises following step
Rapid:
