Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of green grass or young crops that can improve shrimp culture yield and quality
The high-efficient ecological cultivation method of shrimp.
Background technology
Freshwater shrimp, also known as river prawn, scientific name Macrobrachium nipponensis (Macrobrachium nipponense), category shell-fish, Decapoda,
Swimming suborder, Eucyphidea, long-armed section, pond crayfish category, are a kind of Main economic shrimps for being distributed widely in freshwater.Freshwater shrimp nutrition
Value is abundant, fine and tender taste delicious flavour, is a kind of rare aquatic products being loved by people.The economic value of freshwater shrimp is very high,
It is one of traditional economy shrimp species in China's freshwater aquaculture industry.But at present, due to existing in shrimp culture, the speed of growth is slow, feed
Cost is high, yields poorly, the shortcomings of specification is small, causes the enthusiasm for cultivating freshwater shrimp not high, shrimp culture industry slower development, it is impossible to full
The consumption demand in sufficient market.
The content of the invention
The present invention solves the technical problem of a kind of high-efficient ecological cultivation method of freshwater shrimp is provided, this method can solve
Problem present in certainly current shrimp culture, improve the yield and quality of shrimp culture.
The technical solution adopted by the present invention is:
A kind of high-efficient ecological cultivation method of freshwater shrimp, comprises the following steps:
(1) shrimp ponds prepare：Pond area is maximum to be no more than 5 mu, depth of water 0.8-1m；Pond four forms certain slope towards bottom of pond
Degree, slope ratio are 1:2-3, and tilted to discharge outlet one side；Pond Silt thickness is no more than 10cm；Water inlet is installed by screen pack；
(2) shrimp ponds sterilize：In above-mentioned shrimp ponds elder generation water filling 10-20cm, then using quicklime slurrying full pool spilling head, after 24h
Bed mud is stirred, is then filled to 30-50cm；
(3) pasture and water plantation and management：Shrimp ponds bottom waterline position after sterilization, along pond periphery, apart from pond bank
Pasture and water are planted at 2-5m；Pasture and water are not planted in pond periphery at interval of a segment distance, reserve the region for not planting a pasture and water band (i.e.：Just
In freshwater shrimp ingests and catches " shrimp road "), for placing cage net and feeding bait；After decomposed fermentation being discharged after plantation pasture and water
Farm manure afterwards, fills new water 10-15cm as base fertilizer；Pasture and water density is controlled, pasture and water area is no more than pond area
30%；Pasture and water growth district is controlled, thoroughly pasture and water of the removing in the 1.5m regions of bank, the pasture and water among pond highly keep
The 10-20cm below the water surface；
(4) seed is put in a suitable place to breed and managed：At the beginning of late July to August, body is launched into shrimp ponds by the quantity of every mu of tail of 7-8 ten thousand
A length of more than 2cm shrimp seedling；2-3 weeks after shrimp seedling pond-inputting, a small amount of silver carp fry and variegated carp fry are launched；Between the 9-10 months, Shi Shengshi
Grey 10-15kg/ mus, it is numerous to suppress the autumn；
(5) water quality management and oxygenation：After shrimp seedling pond-inputting, once new water was filled per 5-7 days, until depth of water 0.8-1.0m；It is high
Warm season supplements 1-2 new water；The shrimp pool configures aerator oxygenation；
(6) management is fed：Feed is that pond crayfish mixed feed and dregs of beans mix in proportion, and is once fed at dusk daily,
The next morning checks feed residual volume, and feeding volume is adjusted daily according to the situation of change of the situation of ingesting and water temperature weather；
(7) caught into shrimp：As shrimp seedling length 5cm more than a length of to body, listing is caught with cage net wheel.
Currently preferred technical scheme is as follows：
(1) shrimp ponds prepare：Pond area is 2-3 mus；Pond type is rectangle, east-west；Pond slope ratio is 1:3；Water inlet
The bolting silk mesh bag filtering of 60~80 mesh is installed at mouthful；
(2) shrimp ponds sterilize：In above-mentioned shrimp ponds elder generation water filling 15cm, then using quicklime slurrying full pool spilling head, iron is used after 24h
Rake stirs bed mud, is then filled to 30cm；The release amount of quick lime is 100-120kg/ mus；
(3) pasture and water plantation and management：Shrimp ponds bottom waterline position after sterilization, along pond periphery, apart from pond bank
The small ring of the circle of plantation two at 2-5m, line-spacing and spacing in the rows are 2m；The pond both sides of pond North and South direction, one is reserved at interval of 5m
Wide 2m or so the region band for not planting pasture and water is (i.e.：It is easy to " the shrimp road " that freshwater shrimp ingests and caught), for placing cage net and throwing
Feed bait；The farm manure is muck；The release amount of the farm manure is 120-150kg/ mus；
(4) seed is put in a suitable place to breed and managed：At the beginning of late July to August, body length is launched into shrimp ponds by the quantity of every mu of 70,000 tails
For more than 2cm shrimp seedling；2 weeks after shrimp seedling pond-inputting, every mu is launched the tail of silver carp summer flower seedling 10, launches the tail of variegated carp summer flower seedling 4；Under September
In ten days, every mu is applied 10-15kg quick limes once, and it is numerous to suppress the autumn；
(5) water quality management and oxygenation：After shrimp seedling pond-inputting, once new water was filled per 5-7 days, until depth of water 0.8-1.0m；It is high
Warm season supplements 1-2 new water；Shrimp pool configuration 1.5kw paddle aerators one, are opened before fair weather, morning to sunrise
Aerator, extend the aerator available machine time in rainy weather；
(6) management is fed：Feed is pond crayfish mixed feed and dregs of beans in mass ratio 1:1~3:7 ratio is well mixed, often
It once feeds at dusk, and the next morning checks feed residual volume, daily according to the situation of change of the situation of ingesting and water temperature weather
Feeding volume is adjusted, each feed increase and decrease control is in 250g or so；
(7) caught into shrimp：As shrimp seedling length 5cm more than a length of to body, listing is caught with cage net wheel.
In the step (4), at the beginning of shrimp seedling puts time preferred August in a suitable place to breed；In the step (5), preferred sieve of pond crayfish mixed feed
Family name's pond crayfish mixed feed；The blend proportion preferred mass of pond crayfish mixed feed and dregs of beans is than 3：7；The method for checking feed residual volume
For：Using the sediments of special close eye diddle-net scraping bottom of pond, whether inspection wherein has the fresh or feed remnants that go mouldy.
The beneficial effects of the invention are as follows:The Dianshan Lake freshwater shrimp high-efficient ecological cultivation method of the present invention, it is simple and easy；Pass through kind
Plant pasture and water, ichthyophagy (silver carp seedling) is filtered in collocation, reduce mixed feed ratio, rationally effectively feed, controls pasture and water density, aerator to increase
The management methods such as oxygen, the content of poisonous and harmful organic matter and remaining bait etc. can be farthest reduced, reduce cost input, protected
Water holding matter is pure and fresh；The time is put in a suitable place to breed by postponing shrimp seedling and generation that applying quick lime can suppress autumn breeding seedlings；By every on pond side
Be spaced a distance and reserve one and do not plant " shrimp road " that pasture and water are easy to freshwater shrimp to ingest and catch, can promote freshwater shrimp ingesting and it is raw
It is long；Small this pasture and water of ring are planted in shrimp ponds, can not only be purified water, increases dissolved oxygen, sunshading and temperature reducing, bait is provided to lobster,
And the four seasons can also be kept evergreen, build good ecological environment, for lobster it is movable, it is hiding, shelling, it is grown quickly,
The incidence of disease is reduced, improves survival rate.The freshwater shrimp cultivated in the present inventive method, yield is high, quality is good, big standard commodities shrimp ratio
Height, single batch of cultivation per mu yield reach more than 110kg, and for commodity rate up to more than 60%, culture benefit is good, promotes shrimp culture production
The sound development of industry.
