Abstract
The invention discloses a kind of method for being combined cultivation Macrobrachium rosenbergii with gas stone oxygenation using aeration oxygen replenishing, removed the evil using ozone as sterilization material, oxygen atom with strong oxidizing property can reach the purpose of sterilizing, and another product oxygen of ozone decomposed, water body will not be polluted, the dissolved oxygen concentration of water body can also be increased；Acted synergistically using water-bed aeration oxygen replenishing and gas stone oxygenation two ways, effectively improve the dissolved oxygen concentration of culture pond water bottom, reached and improve the activity of Macrobrachium rosenbergii and the purpose of survival rate.
Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to one kind is combined foster using aeration oxygen replenishing with gas stone oxygenation
Grow the method for Macrobrachium rosenbergii.
Background technology
Ozone has very strong sterilizing, taste removal, discoloration, the characteristic of degradation of organic substances as a kind of strong oxidizer, and will not
Residual is produced, is had been widely used in sea, freshwater aquiculture and nursery production.Research shows, breeding water, energy are handled with ozone
Effectively suppress the pathogenic microorganism in the cultivation of the aquatic animals such as fish, Shrimp waste, shellfish, remove harmful bacteria, debirs, oxygen
Change nitrite nitrogen and ammoniacal nitrogen.
Macrobrachium rosenbergii Burden-Swimming Ability of KM is poor, and typical case battalion dwells life at bottom, its consumption rate height, to low dissolved oxygen stress ability very
Difference.When bottom dissolved oxygen will death by suffocation less than 1mg/L.In 25-30 DEG C of water temperature, dissolved oxygen content must not be less than 3mg/
L, being not so easy to stress be dead.The survival rate highest in 25-29 DEG C of water temperature.Dissolved oxygen is that influence aquatic animal existence is most direct
The factor.Macrobrachium rosenbergii lives in bottom in itself, excreta substantially also in bottom, therefore bottom is particularly easy to accumulate organic matter,
In addition the oxygen of redox reaction consumption bottom water, bottom hypoxgia influence normal bacteria nitration reaction, cause vibrios, thermophilic aqueous vapor
The anaerobic bacterias such as monad grow, therefore how to keep water bottom dissolved oxygen all the time in more than 3mg/L, and this is cultivation Roche natural pond
A difficult point for shrimp.
The content of the invention
The present invention provides a kind of method for being combined cultivation Macrobrachium rosenbergii with gas stone oxygenation using aeration oxygen replenishing, improves cultivation
The dissolved oxygen concentration of pool water body, improve shrimp body yield and survival rate.
A kind of method for being combined cultivation Macrobrachium rosenbergii with gas stone oxygenation using aeration oxygen replenishing, including step in detail below：
（1）Pond condition：
Pond depth of water average out to 1.6-1.8 rice, bottom of pond is flat, enters draining conveniently, and each pond configures waterwheel aerator 2,
2, bottom aerator, pond low setting have the disk of nanometer aeration pipe 8 being connected with air compressor, the low laying 80-100 mesh gas stones in pond；
（2）Clean up the pond and training water：
Use pond cleaning with bleaching powder, 10-20 centimetres of water of band, with 30-50mg/kg water concentration full pool spilling head；
After cleaning up the pond, Ozone Water is used as pond waters, is started to intake putting seedling the last week, can first be intake after 40-50cm, use life
Thing rich water treasured 75kg/hm2, slowly water inlet adds biological rich water treasured to water level 80-120cm, and according to water colour and transparency afterwards；
（3）Shrimp seedling is selected with putting in a suitable place to breed：
Opening aerator makes dissolved oxygen in pond be not less than 5mg/L, and the pH value for adjusting culturing pool exists in 7.5-8.5, control water temperature
25-30 DEG C, shrimp seed of macrobrachium rosenbergii is launched, throw-in density is in 15-20 tails/m2；
（4）Feedstuff feeding：
Put in a suitable place to breed in latter week, do not feed feed, feed 2-4 time daily afterwards, uniformly splashed feed along pond surrounding, often 3-4
Hour feeds once, and basic feeding volume is the 8-15% of body weight, and according to weather and the appropriate increase and decrease of situation of ingesting；
（5）Daily management：
1., per spilled once within 6-10 days bacillus subtilis microbial agent, launch dosage in 0.8-1.2g/m3, high temperature period is every 4-7
It spilled once microbial inoculum, control 25-30 DEG C of water temperature；
2., daily noon open aerator 1-2 hours, and according to weather condition open aerator, put 1-2 Zhou Houkai in a suitable place to breed in shrimp seedling
Open air compressor, daily oxygen determination 2-3 times, ensure that Dissolved Oxygen in Water maintains more than 4.0mg/L all the time, while control water body
PH value is in 7.6-8.5.
Wherein, the step（1）Middle gas stone layout density is 5-10/m2。
Wherein, the step（2）In by train water make water present yellow green, light brown, brown, 30-40 lis of transparency
Meter Wei Yi.
Wherein, the step（2）Middle Ozone Water water source is fresh water, comes from stream, after precipitation, sand filter, ozone machine
It is re-introduced into culture pond, the content of ozone in water is 0.2-0.5mg/L.
Compared with prior art, the present invention has advantages below：
（1）The present invention use ozone to be removed the evil material as sterilization, securely and reliably, efficient, ozone decomposed into there is strong oxidizing property
Oxygen atom can reach the purpose of sterilizing, purify water, and another product oxygen of ozone decomposed, dirt will not be caused to water body
Dye, the dissolved oxygen concentration of water body can also be increased；Discontinuity adds bacillus subtilis during cultivation, can directly utilize nitric acid
Salt and nitrite, the organic matter macromolecular such as the residual feed and excreta in shrimp-cultivation pool, spoil can be resolved into small molecule has
Machine thing, promote hydrogen sulfide, the oxidation of nitrite and the decomposition of ammonia nitrogen in water body, stable water body environment, water body ring can be improved
The dissolved oxygen in border.
（2）Using water-bed aeration oxygen replenishing and gas stone oxygenation two ways in the present invention, air is compressed by compressor, led to
Piping enters diffuser -- the aeration tube being positioned in water body, then is diffused into by the micropore of diffuser in water body, while gas
By the way that gas stone can be entered after pipeline, microporous bubble is produced in water, bubble is soluble in water, so as to reach the increasing to pool bottom water body
Oxygen purpose, the synergy of two kinds of oxygenation ways, the contact area of water body and air in culturing pool is increased, so as to add sky
Oxygen enters the amount of water body in gas, as this effect of the propulsion of culturing time is more obvious, reaches the activity for improving Macrobrachium rosenbergii
And the purpose of survival rate.
