Description
Technical field
The invention belongs to technical field of aquaculture more particularly to a kind of Eriocheir sinensis winter protect cream temporarily support equipment and its
Using.
Background technique
Currently, the prior art commonly used in the trade is such that the market price of Eriocheir sinensis has a feature: mid-autumn,
National Day, New Year's Day, these red-letter days in the Spring Festival, the market price is relatively high.Especially the Spring Festival when, river crab market price is very high, and supplies
It should not ask.But it is not also very mature that Eriocheir sinensis winter, which temporarily brings up on fertilizer technology, at present, on the one hand, survival rate can not protect
There is the problems such as cream of losing flesh, fall in card, another aspect river crab, and quality not can guarantee.
In conclusion problem of the existing technology is:
It is not also very mature that Eriocheir sinensis winter, which temporarily brings up on fertilizer technology, at present, on the one hand, survival rate not can guarantee, separately
There is the problems such as cream of losing flesh, fall in one side river crab, and quality not can guarantee.
Solve the difficulty of above-mentioned technical problem:
Problem above to be solved must set about from following several respects: first is that how to select energetic river crab；Second is that how to adjust
Good temporarily feeding river crab water quality, third is that how river crab bait is arranged in pairs or groups and fed to science；Fourth is that the layering in view of temperature in the water in winter is poor
It is different, the temporarily feeding position of net cage in water how is adjusted, builds a suitable growing environment to river crab.
Solve the meaning of above-mentioned technical problem:
During river crab winter temporarily supports, under the premise of guaranteeing river crab quality, river crab survival rate is improved, during compensating for the Spring Festival
The blank in river crab market extends river crab living body Time To Market, improves the Additional Value of Commodities of river crab.Meanwhile it being supported for vast river crab
The river crab for growing family offer cost efficiency temporarily supports solution.
Summary of the invention
The characteristics of for present river crab market, the present invention provides a kind of Eriocheir sinensis winters to protect the equipment that cream is temporarily supported
And its application can promote the motility rate of temporarily forming of river crab to 90% or more while guaranteeing river crab quality.
The invention is realized in this way a kind of Eriocheir sinensis winter, which protects cream, temporarily supports equipment, the Eriocheir sinensis winter

Without crab net cage: whole lift-off waters surface；Net cage pulley is inspected periodically, whether net cage balances, and whether there is or not breakage, ropes for net cage
Whether tie firm.
Administration of health: floating on water weeds, divine force that created the universe salvaging in time are handled, hygiene on boardwalk.
The casualties checks: each net cage is checked, is recorded.
In the embodiment of the present invention, temporarily support the selection technique of feeding river crab: should select to turn over it is fast, creep that fast, four limbs are sound, step
Energetically, the river crab caught is not changed hands as temporarily feeding object.3-5 river crab is respectively chosen by requirements above male and female, by one piece 0.5 meter of block of light
Slide plate material tilts 45 °, sees whether river crab can rush forward, appropriate to increase and reduce plate angle, can rush forward to most of river crab,
Fixed angle position.Erect at the same angle equipped with river crab frame in, it is suitable for reading to connect empty frames, can be escaped from by plate come river
Crab, the exactly energetic river crab for being suitble to overwintering fattening.
Put technology in a suitable place to breed: male crab mother crab divides cage temporarily to support；Temporarily feeding initial time is generally annual December, and water temperature is lower than 10 DEG C
When；Every cage breeding density is 70-85Kg.
Feeding technology: the public every 50Kg of crab feeds the chilled fish of 1Kg daily, and female every 50Kg of crab feeds the chilled fish of 500g daily.When nursing
It can take the circumstances into consideration to increase and decrease by food amount.When feeding, net cage is left the water 50cm, and the sufficient depth of water is stayed, to buffer, to prevent net cage to crab
The unnecessary injures and deaths of excessively high crab mentioned.
Soil water regulation: noon, 12:00-1:00 detected water quality, observed the algae phase in water, suitably supplement algae, EM
Bacterium.Real-time monitoring dissolved oxygen, especially attention night dissolved oxygen, dissolved oxygen are lower than 3mg/L, open matched bottom oxygenation or waterwheel increases
Oxygen machine.Cage is mentioned when necessary goes out the water surface or timely medication.
Daily management: (1) net cage management: there is crab net cage: having to daytime fully fall in the water surface or less (3-5cm), energy
It sees crab gold pawl, white tripe, guarantees superficial water circulation；Net cage goes out water surface 5-8cm after night feeding.No crab net cage: it all mentions
From the water surface, without chilled fish in net cage.Net cage pulley is inspected periodically, whether net cage balances, and for net cage whether there is or not breakage, whether knot is firm
It leans on.(2) administration of health: floating on water weeds, divine force that created the universe salvaging in time are handled, and keep hygiene on boardwalk.(3) casualties inspection
Look into: each net cage is checked that special messenger's record pays attention to the food amount of feeding, the big attention tracking of mortality.
When progress river crab winter guarantor cream is temporarily supported, mating nano oxygen enriching system and waterwheel aerator play circulating water flow and increasing
The effect of solubilization oxygen.By river crab according to different size, male and female is separated, and each net cage is temporarily supported according to 70-85Kg.The public every 50Kg of crab is every
It feeds the chilled fish of 1Kg, and female every 50Kg of crab feeds the chilled fish of 500g daily.It can take the circumstances into consideration to increase and decrease by food amount when nursing.Noon 12:00-
1:00 detects water quality, observes the algae phase in water, suitably supplement algae.Real-time monitoring dissolved oxygen, especially attention night dissolved oxygen,
Dissolved oxygen is lower than 3mg/L, opens matched bottom oxygenation or water-mill oxygen increasing machine in time.From mid-December to mid-March in next year, 2.5
Two -3.5 liang of female crab, 3.0 liang -5.0 liang of male crab, survival rate can reach 90% or more, and cream Man Huangfei, best in quality.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
