Abstract

The invention discloses a kind of prawn culturing method using ozone combination microbial technique, removed the evil using ozone as sterilization material, oxygen atom with strong oxidizing property can reach the purpose of sterilizing, afterwards efficient probiotics is launched in the breeding water body after ozone processing, on the one hand later stage can eliminate ammonia nitrogen in breeding water body by discontinuity photosynthetic bacteria of splashing, the harmful substance such as hydrogen sulfide and organic acid, improve water body, on the other hand the breeding of blue-green algae can be suppressed, and green alga, diatom has but obtained effective breeding, water colour is in pale green, the kilters such as yellowish-brown, positive role is served to pond algae structure regulating, it compensate for the influence that the processing of single use ozone is brought to aqueous bio, add aqueous bio vigor and shrimp seedling resistance against diseases.

Description

A kind of prawn culturing method using ozone combination microbial technique
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of prawn using ozone combination microbial technique is supported Grow method.
Background technology
China is prawn producing country maximum in the world, and the occurrence degree of disease of prawn has what is constantly strengthened to become in recent years Gesture, shrimp culture industry face bottleneck.In prawn culturing water body, planktonic algae is the main body bait in shrimp ponds, its species, density Maintenance to Shrimp pond ecosystem plays a crucial role, and there is extremely close relation between being grown with prawn.How to maintain Good water colour, the excellent planktonic microalgae of culture, the generation that reduces vibrios disease are always to receive much concern during prawn culturing One of subject matter.
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.
Although the effect that ozone is handled breeding water is preferable, ozone has also been eliminated all in water while sterilization Food organisms, such as nitrobacteria, algae beneficial organism.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of prawn culturing using ozone combination microbial technique Method, using Ozone Water cultured prawn, probiotics is launched with reference to reasonable, promotes beneficial microbe and algae in breeding water body Growth, increase aqueous bio vigor and shrimp seedling resistance against diseases.
A kind of prawn culturing method using ozone combination microbial technique, including step in detail below:
(1)Pond disinfection:
Put before seedling 20-30 days, thorough disinfection is carried out to band water pond bottom and surrounding with bleaching powder, dosage presses 20g/m3 Concentration Full pool spilling head, drain within second day water, exposure 7 days;
(2)Pond culture food organisms and rich water:
Ozone Water is used as pond waters, starts to intake putting seedling the last week, can first intake after 40-50cm, use biological rich water Precious 75kg/hm2, slowly water inlet adds biological rich water treasured to water level 80-120cm, and according to water colour and transparency afterwards;
(3)Apply microorganism formulation:
Putting 2-6 days of before seedling, high-efficiency microorganism preparation of uniformly being splashed into pond, viable bacteria concentration it is stable every milligram 2,000,000,000 with On, dosage stirs water 2-3 hours splashing while opening aerator, is uniformly distributed strain in 1.0-2.0mg/L;
(4)Seedling is selected to put in a suitable place to breed:
The health young shrimp that body long size is 0.8-1cm is chosen to be put into culture pond, when putting seedling, 22-26 DEG C of water temperature, pH 7.5- 8.5, breeding density is ten thousand tails of 2-4/mu;
(5)Aquaculture management:
A pond water was handled using ozone generator per 4-7 days, per the photosynthetic bacteria for adding 10ppm concentration for 2-4 days, at ozone Reason is launched to stagger one day and launched with bacterium, while controls water pH value in 7.6-8.5;Change water once daily, add ozone concentration The water body after 0.2mg/L processing, quantity of exchanged water is the 10-20% in former pond, and every blowdown in 2 days is once;
(6)Feedstuff feeding:
Shrimp seedling starts to feed feed after launching 3-6 days, from 6 points to 21 points, is fed once per 3-4 hours, feeding after afternoon Amount accounts for the 50-60% of whole day feeding volume.
Wherein, the step(2)In by rich water make water present yellow green, light brown, brown, 30-40 lis of transparency Meter Wei Yi.
Wherein, the step(2)Pond water water source come from beach sand filter phreatic water, through precipitation, sand filter, ozone machine After be re-introduced into culture pond, the content of ozone in water is 0.2-0.5mg/L.
Wherein, the step(3)Middle microorganism formulation refers to photosynthetic bacteria, bacillus amyloliquefaciens, denitrifying bacteria Mix bacterium agent.
Compared with prior art, the present invention use ozone to be removed the evil material as sterilization, securely and reliably, efficient, ozone decomposed Into the oxygen atom with strong oxidizing property can reach the purpose of sterilizing, launched afterwards in the breeding water body after ozone processing efficient Probiotics, early stage blue-green algae account for main advantage, middle and later periods green alga turns into sociales, and blue-green algae is referred to as having in aquaculture Evil algae, therefore carries out shrimp seedling after microorganism formulation is launched and puts in a suitable place to breed again in a few days, now exist in water body substantial amounts of boat-shaped algae, Melosira, crisp bar algae etc. and green alga and desmids with flagellum, can directly as the high-quality bait of shrimp seedling, water stabilization, after On the one hand phase can eliminate the nuisances such as ammonia nitrogen, hydrogen sulfide and organic acid in breeding water body by discontinuity photosynthetic bacteria of splashing Matter, improve water body, on the other hand stabilizing water quality can suppress the breeding of blue-green algae, and green alga, diatom obtained it is effective numerous Grow, water colour serves positive role to pond algae structure regulating, compensate for single make in kilters such as pale green, yellowish-brown The influence brought to aqueous bio is handled with ozone.
