Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of crab pool multi items polyculture method.
Background technology
Aquatic products are the important sources of mankind's high-quality protein, and it is rich in high-quality protein, amino acid, vitamin and mineral
Deng, and quantity and ratio meet human body needs, particularly containing human body requirements amount larger leucine and lysine.With people
Income level raising, increasing people starts the primary need using trophism demand as food consumption, aquatic products
The trend risen year by year is presented in consumption proportion.At this stage, China carries out the aquatic products species of large-scale cultivation up to kind more than 50, work
Factoryization cultivation, deep-water net cage culture, ecologic breeding etc. are quickly grown.Aquaculture had turned into the important composition portion of China's agricultural already
Divide one of main growth factor with Rural Areas at Present economy.
In recent years, the fresh water pearl market price was relatively low, and the cultivation of fresh water pearl freshwater mussel has been enter into meagre profit or even the condition lost, very
The aquaculture cost of more fresh water pearl freshwater mussel culturing areas is high, benefit is low, causes cultured area atrophy serious.In order to tackle market
The low impact to water pearl culture industry, by ecological with breeding water body, exploration is a kind of on the basis of main foster freshwater mussel
Upper set supports the Novel cultivation method of other a variety of aquatic products, to increasing benefit, drives band water pearl culture industry living, carries
High numerous fishmen cultivate enthusiasm, and tool is of great significance.
The content of the invention
To solve above-mentioned the shortcomings of the prior art, the present invention provides a kind of crab pool multi items polyculture method, the cultivation
The method whole culture-cycle does not have to use medicine substantially, and the Product quality and safety to breed variety provides sound assurance, and
And water ecological setting is made full use of, mixed breeding technology is novel, and operation is scientific and normal, not only increases the quality of aquaculture, more
Considerably increase the economic benefit of aquaculture.
To achieve these goals, the following technical scheme of present invention offer, a kind of crab pool multi items polyculture method, including with
Lower step：
（1）Pond prepares：In December last year, water is drained, allow bottom of pond to freeze and shine a winter, the mid-February in the coming year, every mu with life
Full pool spilling head after lime 70~100kg slurryings；Clean up the pond after end, throw organic fertilizer 150~200kg/ mus after applying fermentation, then turn over
Plough smooth；50~70cm of water filling is deep after 7d, is enclosed with 5 window screenings twisted in bottom of pond and sets fence, bottom of pond is divided into pasture and water protection zone and ring
Two pieces of Gou Zanyang areas, waterweed, pasture and water protection zone plantation hydrilla verticillata, water filling after plantation, water filling are transplanted in circular groove Zan Yang areas
When, water inlet is filtered with 20 mesh mesh sheet；After water filling terminates, spiral shell living is sprinkled into pond successively, average of the whole year mu throws spiral shell
500kg；

Per tail 0.25kg bighead, specification is the silver carp per tail 0.1kg；Early June, put a length of more than the 5cm of body mandarin fish seedling in a suitable place to breed；
（3）Feedstuff feeding：The river crab season of growth, day feeding volume are controlled the 4% ~ 10% of full pond crab shrimp body weight；Feeding time is every
Its 8-9 point, 17-18 points are respectively fed once, and feed in the morning feeds the 30% of total amount day, feeds remaining 70% at dusk；
（4）Regulating and controlling water quality：Early stage is cultivated, holding water transparency is 25-35cm；The middle and later periods is cultivated, by filling new water, discharge
Old water, increase water transparence to more than 50cm, more than dissolved oxygen amount 5mg/L；Every 15 ~ 20d, 1 water splashing is used alternatingly
Quick lime or using photosynthetic bacteria, both use more than interval time 72h, adjust the pH value of water between 7 ~ 8.5；Every 10~
15d changes water 1 time, and quantity of exchanged water is the 1/3 of breeding water body；6~August part changes water 1 time per 7d, and quantity of exchanged water is the 1/3~2/3 of water body,
And time opening micro-pore oxygenation equipment；
（5）Disease control：Rotation carries out disease control using quick lime and photosynthetic bacteria, kills water only using fine worm mid-September
The infusorian of body.
Further, the pond depth is 2.5-2.8m, and pond periphery is provided with wide 8m, deep 1.2m circular groove, in pond
Centre is provided with the platform for accounting for pond area 1/2.
Further, anti-escape wall is built from calcium-plastic board around the pond, calcium-plastic board is earthed interior 15cm, and top is higher by the pool
Ridge 60cm, calcium-plastic board corner are done in the arc-shaped.
Further, the pond bottom is provided with micro-pore oxygenation equipment, Roots's drum of pond pool mouth 7.5 kilowatts of power of configuration
Blower fan 1, average every mu of water surface laying 90m microporous pipelines are placed in above bottom of pond at 15~20cm.
Further, the density of the waterweed plant is：Spacing in the rows × line-spacing=1m × 1m, dosage are 200kg/ mus, plantation
Area accounts for the 60% of pond area.
Further, the hydrilla verticillata gemma dosage is 1kg/ mus.
Further, first 5-15min is embathed with 3 ~ 5% salt solutions when the crab, shrimp, fingerling stocking.
Further, the freshwater shrimp injected volume is 7.5kg/ mus, and crab species injected volume is 800/mu, and bighead injected volume is
8 tails/mu, silver carp injected volume are 10 tails/mu, and mandarin fish seedling injected volume is 12 tails/mu.
In summary, the present invention has the advantages that as a result of such scheme：
1st, polyculture method of the present invention has the advantages that reliability is high, green, yield is high, quality better, high financial profit, simultaneously
There are extensive market prospects in the application and popularization of aquaculture.
2nd, various pasture and water are not only the bait of river crab, and its hidden and habitat, pasture and water in polyculture method of the present invention
The ammonia nitrogen in water body can be absorbed, regulation pH values, dissolved oxygen, reduces harmful substance；Pond suitably set, which supports mandarin fish and can eat to work as, to be close on
The shrimp inferior of parent's breeding, reaches the purpose saved feed and reduce pond load capacity, and can also improve into shrimp specification and support
Grow benefit.
