Abstract
The invention discloses a kind of American shad stereo ecological cultivating systems, it is launched including 1. new meters of shrimps and plants three steps such as liana outside stable 3. greenhouse of the ecosystem of 2. creations, it solves the problems such as American shad is difficult to clear up in Summer High-Temperature Times residual bait, ecology is difficult to balance, water body transpiration hilsa herring is difficult to adapt to through the invention, provides a kind of American shad stereo ecological cultivating system.
Description
Technical field
The present invention relates to aquaculture field, specially a kind of hilsa herring cultural method.
Background technique
In China, the Changjiang river hilsa herring, hairtail and globe fish simultaneously be known as " the Changjiang river three delicacies ", but the eighties due to overfishing,
The reasons such as environmental disruption, wild the Changjiang river hilsa herring almost become extinct.Short in the market to make up the Changjiang river hilsa herring, China is from 20
Start to introduce American shad the nineties in century and carries out large-scale artificial propagation, the fish and the Changjiang river hilsa herring shape is very much like, taste
Road is close, on the market the deep favor by consumer.
In the breeding process, American shad is edgy, stress reaction is strong, and accommodative ability of environment is poor.After long-term cultivation just
The corrupt deposit such as a large amount of residual bait, excrement can be generated in bottom, then meet summer high temperature season, this kind of deposit will ferment
Harmful substance is generated, water body environment is destroyed, causes to bear, leads to fish body poisoning or dead.Usual raiser can be in aquaculture pond
Street cleaner is added to clear up excrement, residual bait, but street cleaner likes boring the low soil layer in pond, be easy to make generally in cultivation bottom of pond portion activity
At water pollution, if a large amount of launch, extremely strong viability and fertility are easy to compete living environment with American shad, break
Bad breeding ecological balance.Summer high temperature in order to prevent, water body are rising, and raiser can hide sunshade net outside greenhouse or with spraying
Mode sprays water to greenhouse and carries out Physical temperature-lowering, but such processing mode can also generate drawback, as sunshade net heat absorption can be in greenhouse
Upper layer formation temperature area will also result in larger impact to water temperature in aquaculture pond；The water of sprinkling can be drenched to greenhouse bottom, be gone down for a long time
The loosening that will cause greenhouse bottom cement, influences stability of the greenhouse structure, at the same the engineering extremely labor intensive, material resources and when
Between, effect and effect are also limited.Therefore, how to allow American shad to spend Summer High-Temperature Times safely to cultivate at hilsa herring
It has to solve the problems, such as in journey.
Summary of the invention
It is difficult to clear up in Summer High-Temperature Times residual bait it is an object of the invention to solving American shad, ecology is difficult to balance, water
The problems such as body transpiration hilsa herring is difficult to adapt to provides a kind of American shad stereo ecological cultivating system.
To achieve the above object, the invention provides the following technical scheme: in summer high temperature season, first in aquaculture pond
Algae is added and carries out rich water, generates a large amount of wheel animalcules, cladocera, launches new rice shrimp secondly to decompose residual bait, excrement etc., finally launches
Such as black carp, grass carp, crucian, mandarin fish fish form algae, wheel animalcule cladocera, shrimp, such a stable ecosystem of fish,
Promote substance circulation and energy flow.It, can be periodically in culturing pool simultaneously to prevent the excessive breeding for stablizing flora in aquaculture pond
Middle that suitable sea salt is added, adjusting salinity to 6 ‰ -10 ‰ launches new microorganism formulation, and aquaculture pond is made to have purification function,
Flora continuous updating.Liana, such as sponge gourd, Boston ivy, grape are planted outside greenhouse simultaneously, carries out three-dimensional culture, is utilized
Solid space stops strong light direct beam, absorbs heat, forms natural protective umbrella, creates the environment for being conducive to hilsa herring life.
Specifically, a kind of American shad stereo ecological cultivating system, includes the following steps.
(1) new rice shrimp is launched in aquaculture pond, the residual bait and excrement of exploded bottom accumulation: the throw-in density of new rice shrimp is
0.5—1kg/m3。
(2) it creates the stable ecosystem: launching algae and carry out rich water, so that water body is generated a large amount of wheel animalcule cladocera raw
Object is added seawater and adjusts salinity, eliminates the stabilization flora in aquaculture pond, suitable microorganism formulation is then added, purifies water,
New flora is generated, the flora in aquaculture pond is updated, finally launches the fish such as black carp, grass carp, injected volume is 1-2/m3, shape
At the stable ecosystem.
(3) liana is planted outside greenhouse, absorbs heat, form natural protective layer: liana can be most common
Sponge gourd, Boston ivy, grape etc., one layer of natural protective umbrella can be formed outside aquaculture pond with three-dimensional culture, stop summer
Qiang Guang absorbs heat, blocks heat-conduction effect, can make at a temperature of reaching under the more original sunshade net of temperature in culturing pool
4-5 DEG C of drop.
Preferably, a kind of above-mentioned American shad stereo ecological cultivating system, in step (2), seawater adjusts salinity
Range varies with temperature control 6 ‰ -10 ‰, and salinity increases with the rising of temperature, reduces again later.
Preferably, a kind of above-mentioned American shad stereo ecological cultivating system, in step (2), the microorganism that is added
Preparation is mainly the microorganism formulation of 3 class of bacillus subtilis, Bacillus acidi lactici and photosynthetic bacteria, and launching dosage is respectively 15-30g
/m3、10-20g /m3、1-2L/ m3, every 15 days supplements using once, dosage is identical as using for the first time.
Beneficial effect
1. launching, new rice shrimp effectively decomposes residual bait in aquaculture pond, excrement is accumulated.2. residual bait, wheel animalcule, rice shrimp, black carp etc. are cultivating
The stable ecosystem and food chain are formd in pond, and energy is made to have carried out maximum utilizationization.3. being stood using liana
Body cultivation, absorbs heat, reduces the temperature of aquaculture pond, improves the survival rate of the American shad in summer high temperature season.
