Description
Technical field
The present invention relates to river crab son's crab Cultivating techniques fields, and in particular to a kind of son crab cultivation water level water quality kinetic controlling equation
Method.
Background technology
River crab is that China is distinctive famous-brand and high-quality and foreign exchange earning aquatic products, and river crab benefit per mu, that the gross output value has become China is light
Outstanding person in water breed variety, crab farming have become one of the fresh water fishery pillar industry to show unique characteristics in China.For many years
Development, river crab meets the different needs of people's life as one of high-grade aquatic products horn of plenty fishery market, is the fishman people
Increase wealth plays positive promotion and facilitation for foreign exchange earning.
Anhui is China's river crab advantage culturing area, and river crab is Anhui advantage aquatic products.It is riverine, along Huaihe River Lake Area, pond
Pool star sieve gathers, and is the major production areas of river crab, and be included in by the Ministry of Agriculture《National Regional Distribution of Superior Agriculture Products's planning》.In recent years
To come, Anhui river crab industry flourishes, the whole province's year more than 400 ten thousand mu of cultured area, occupies national forefront, 3000 tons of annual export volume,
As the mainstay of aquaculture, yield, the output value, scale and benefit etc. locate national leading position.The annual crab of our province
Kind cultivates area up to more than 100,000 mus, launches about 12 kilograms of juvenile crab.Conventional juvenile crab breeding method, to III phase son crab cultivate at
Motility rate generally only 25% or so, causes the significant wastage of juvenile crab resource.
Invention content
The purpose of the present invention is to provide a kind of young crabs to cultivate water level water quality dynamic control method, significantly improves III phase son
The survival rate that crab is cultivated, while this method is simple and clear, easy to operate practicality, is pure physical method, medicine-less pollution, cultivate at
This is low.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of son crab cultivation water level water quality dynamic control method, includes the following steps：
(1) water quality dynamic control：30 days before juvenile crab pond-inputting, the pond 6~7 days of being exposed to the sun, 5~6cm of then intaking；Juvenile crab pond-inputting
First 19~22 days, eyebright and rye grass were sowed in pond, per acre 67~75g of sowing quantity eyebright, 28~33g of rye grass；Juvenile crab
8~11 days before pond-inputting, increases water level to 9~10cm, do not flood eyebright and rye grass toothed burclover；2 days before juvenile crab pond-inputting, increase water
Eyebright and rye toothed burclover are flooded in position to 20~25cm；
(2) Water level trend controls：When the rigid pond-inputting of juvenile crab, the depth of water is maintained at 20~25cm, when juvenile crab shell metamorphosis was I phase
After young crab, add 4~5cm of water, metamorphosis is after II phase son crab plus 5~6cm of water, and metamorphosis is to add water 10~15cm after III phase son crab；
From III phase son crab to V phase son crab, culture pond water level control is in 40~50cm；It is filtered using the mesh sheet of 55~80 mesh when water inlet.
Preferably, in the step (2), after juvenile crab shell metamorphosis is I phase son crab, full pool spilling head while adding water
The photosynthetic bacteria aqueous solution of 1.5wt%, dosage is 2~3kg per acre.
Preferably, in the step (2), metamorphosis is after II phase son crab, full pool spilling head 1.5wt%'s is photosynthetic while adding water
Bacterium aqueous solution and 1.5wt%EM bacterium aqueous solutions, the photosynthetic bacteria aqueous solution+1.5wt%EM bacterium aqueous solution of 1.5wt% is per acre
Dosage is 3~4kg.
Preferably, in the step (2), metamorphosis is after III phase son crab, full pool spilling head 1.5wt%'s is photosynthetic while adding water
Bacterium aqueous solution and 1.5wt%EM bacterium aqueous solutions, the photosynthetic bacteria aqueous solution+1.5wt%EM bacterium aqueous solution of 1.5wt% is per acre
Dosage is 4~5kg.
Preferably, in the step (2), from III phase son crab to V phase son crab, the photosynthetic bacteria water of full pool spilling head 3.5wt%
The dosage per acre of solution and 2.5wt%EM bacterium aqueous solutions, the photosynthetic bacteria aqueous solution+1.5wt%EM bacterium aqueous solutions of 1.5wt% is
5~6kg.
Preferably, in the step (2), the mesh sheet of 60 mesh should be used to filter when water inlet.
Preferably, in the step (1), sowing quantity eyebright 70g, rye grass 30g per acre.
Preferably, torrential rain is met in cultivating process, suitably deepens water level, prevents water temperature and water quality mutation, causes dead seedling.
The beneficial effects of the invention are as follows：
The present invention uses water filling by stages, and water filling by stages can force the young crab for digging cave under waterline to abandon hole and seek food, prevent
Lazy crab.Mesh sheet should be used to filter when water inlet, to prevent harmful organisms from entering culture pond.Eyebright and rye grass are sowed in pond,
The society of the planktonic organism centered on eyebright and rye grass can be formed, can be provided for the juvenile crab in rigid lower pond abundant agreeable to the taste
Natural bait biology.When the rigid pond-inputting of juvenile crab, the depth of water is maintained at 20~25cm, juvenile crab can be along eyebright and rye grass at this time
Stalk up and down creep, seek food or creep into water body bait and the most suitable water layer of oxygen.
The present invention is further in cultivating process in photosynthetic bacteria aqueous solution of splashing in culture pond, EM bacterium aqueous solutions, favorably
In inhibiting pathogenic microorganism and harmful substance, breeding ecological environment is adjusted, improves dissolved oxygen in water, and promotes normal flora and has
Beneficial algae activated growth；Excreta and residual bait that simultaneously can also be in purifying aquaculture pond, improve water quality, reduce young crab disease.It is photosynthetic
The addition of bacterium and EM bacterium can enhance the diseases prevention anti-adversity ability and absorption function of young crab, be allowed to faster grow,
The present invention is by implementing high-quality crab species large-scale cultivation project, and the experiment of logical multiple spot too much, III found out
Phase son crab cultivates water level water quality dynamic control method.This method is according to the physiology and biological characteristics of young crab different times, by stages
Water filling, and strictly filter, significantly improve the survival rate of III phase son crab cultivation.It is that juvenile crab is cultivated from megalops larva to III phase son crab
The application of one of critical period, this method can provide solid foundation for the cultivation of high-quality crab species.Meanwhile this method is simply bright
, easy to operate practicality is pure physical method, and medicine-less pollution is cultivated at low cost.
