Description
Technical field
The present invention relates to crayfish breeding technique field, more particularly to a kind of aquaculture method of cray.
Background technology
In recent years, cray market is economic freshwater shrimps, because meat flavour is delicious wide welcomed by the people.Because of its omnivorousness, life
Long speed is fast, adaptable and absolute competitive advantage is formed in local environment.Its scope of ingesting includes water plant, algae
Class, aquatic insect, spoil etc., food are also killed each other when deficient scarce.Cray has become important warp in China in recent years
Help breed variety.
With the continuous improvement of people's living standards, people are higher and higher to quality of life requirement, to food quality requirement
Also very high, the demand for the cray that people enrich nutritive value is also in very fast growth, but small dragon currently on the market
Shrimp yield can not meet the active demand of people, since current Water quality is subject to different degrees of pollution so that cray
Living environment constantly deteriorates, and causes cray easily to catch, meanwhile, cray living environment has limitation, current
There are certain drawback for freshwater crayfish artificial breeding, it is impossible to which the meat that cray is effectively ensured is full, it would be highly desirable to improves.
The content of the invention
A kind of the defects of the object of the invention is exactly to make up prior art, there is provided aquaculture method of cray.
The present invention is achieved by the following technical solutions：
A kind of aquaculture method of cray, comprises the following steps：
（1）Pond condition：Selection is had abundant water resources, irrigation and drainage are convenient, water holding capacity is strong, water quality is good, fertile soil, 3-5 mus of area
Pond, depth of water 1m or so, along pond ridge on the inside of dig for the place inhabited of burrowing, the outer ridge around pond will have 1：2.5 slope
Degree, outer high more than the 2m in the ridge, pond stalk width sets 0.5m high in more than 1.5m, and in surrounding, and one layer is done on the inner wall around pond
Smooth anti-escape measure, sets oxygenation measure, and eel grass, hydrilla verticillata, Eichhornia crassipes, water lettuce, spray are in addition planted in pond
The plant such as raw；
（2）Water quality adjustment：Put preceding strict sterilization in a suitable place to breed, control water quality pH, improve water body acid-base value using quick lime, water temperature control exists
20 DEG C, dissolved oxygen should be in 20cm or so in 3-5mg/L, transparency；
（3）The selection of shrimp seedling：When launching shrimp seedling, the consistent seed of same pond selection size specification, will disposably put foot, select
Select that physical strong, appendage is complete, disease-free shrimp seedling carefree, vitality is indomitable；
（4）Shrimp seedling is launched：
A, summer is put in a suitable place to breed based on first the young shrimp hatched then with putting, puts the time in a suitable place to breed in mid or late July, and stocking size is per acre
Young ten thousand tails of shrimp 3-4 of more than 0.8cm；
B, autumn is put in a suitable place to breed based on the big specification shrimp seedling cultivated then with putting or shrimp species, puts the time in a suitable place to breed in mid-August to September, shrimp seedling
Specification is 1.2cm or so, puts ten thousand tails of 2.5-3 in a suitable place to breed per acre, and shrimp species specification is 2.5-3 centimetres, puts ten thousand tails of 1.5-2 in a suitable place to breed per acre；
C, Winter-Spring is put in a suitable place to breed generally in December or March in next year-April, is not met with putting in a suitable place to breed based on the shrimp of listing specification then, per acre
Put -2 ten thousand tail of 1.5 ten thousand tail in a suitable place to breed, cultivated by winter and spring, to June-harvesting listing in July；The saline solution medicine of 3-5% is used before putting in a suitable place to breed
10min is bathed, is carried out disinfection before putting in a suitable place to breed with quick lime to pond；
（5）Bait feeding：Daily daily ration, feeding quantity, which is subject to, has enough, eats up, not staying residual bait, feeds daily 2 times, each 1 time sooner or later, because
Cray mainly feeds at night, and evening feeding volume accounts for the 70%-80% of full-time bait, and bait will be thrown in pool side shallow water, large quantities of
Thrown less during shrimp shell, it is after shell to throw more；
（6）Daily management：A, Water-quality control：Photosynthetic bacteria is used alternatingly and quick lime carries out full pool spilling head to improve water quality, adjust
Water pH value is saved, reduces ammonia-nitrogen content in pond, 1 new water, each quantity of exchanged water are changed every 10-15 days notes when there is allogenic water note to change
For the 1/3 of former pond water, when bad weather, to reduce daily ration, feeding quantity or stop bait throwing in, skim in time in pond residual bait and
Debris, keeps pond cleaning, if finding, lobster is slow in reacting, when trip collection to bank swashes, then illustrates anoxic, to open oxygenation in time
Machine oxygenation or the new water of filling, water transparence are controlled in more than 35cm, when weather overheats, suitably to deepen water, with stabilization
Water water temperature；
B, disease control：While periodically carrying out disinfection to water body, multiannensional-sine, calcium tablet, lactic acid bacteria etc. are added in feed
To strengthen the immunity of cray, monthly splashed with the full pool of 15-20g/m3 tea seed cake leachates, and monthly using once fine worm
Only, while interval uses the prophylactic generations such as water quality improvement king in one week；
C, shell period management：When a large amount of crays shell, hypocalcia is to meet the needs of cray duricrust in water body, so will
Artificially replenish the calcium, the shelling phase is taken orally using ionized calcium using 0.5% additive amount spice, or is directly splashed water using calcium dihydrogen phosphate
Body, during which keeps water body to stablize, forbids using dripping of irritant drugs；
（7）Fishing in due course：Adhere to patrolling the pool within 15 days before fishing, the growth tendency of cray is grasped in time, when cray weight reaches 50g
Caught in due course during the above, vying each other between reduction causes death.
A kind of aquaculture method of cray, step（1）Described in the cultivated area of water plant be to account for pond area
30-35%。
A kind of aquaculture method of cray, step（2）Described in pond water quality pH value be 7-8.
A kind of aquaculture method of cray, step（4）Described in shrimp seedling launch in when putting shrimp species in a suitable place to breed with 3-4%'s
Salt water washing bath 6-10min is sterilized.
A kind of aquaculture method of cray, step（5）Described in bait be after spiral shell or freshwater mussel are crushed and
Dregs of beans class, mixing dish leaf class, wheat, wheat bran be stirred, the shrimp seedling phase based on vegetal bait, according to the 15-20% of weight
Feeding volume is fed, and into shrimp based on animal bait, is fed into shrimp according to the feeding volume of weight 5-10%.
A kind of aquaculture method of cray, step（6）Described in water quality management in water inlet screen filtration, prevent
Harmful organisms enter, and water temperature control is at 20 DEG C ± 2 DEG C.
