Embodiment
Present invention is disclosed a kind of loach microorganism cultivation method, comprise pond and do water, fish fry mark seedling, spice nursing and water quality improvement step:
Step one, pond do water: comprise and cultivate algae and cultivate aquatic bait, wherein:
Cultivate algae: standby 2-3 mu soil one, the pool, utilizes sunshine to be exposed to the sun more than 3 days, utilize solar UV sufficiently sterilised at the bottom of the pool, then be spread on soil surface, the pool with quicklime is evenly dry, then intake 30 centimeters, wait for for subsequent use after 3 days; Comprise afterwards and add microbial bacterial agent and cultivate the algae bio factor, wherein:
Add microbial bacterial agent: add complex micro organism fungicide 20 kilograms and photosynthetic bacteria 10 kilograms by every mu of water surface, evenly splash to water surface for aquaculture, at the bottom of the bubble Neng Shi pool, the pool, organic matter ferments, and is converted into nutrient source, thus enhances natural, ecological water environment; After 3-5 days, water is filled into 60 centimeters for subsequent use; Described complex micro organism fungicide is made up of the microorganism of following mass percent: lactic acid bacteria 70%; Saccharomycete 25%; Bud is satisfied bacillus 2%; Symbiosis beneficial bacterium 3%; Wherein, lactic acid bacteria contains acetic acid bacteria and Bifidobacterium Bifidum; Symbiosis beneficial bacterium contains photosynthetic bacteria and actinomycetes;
Cultivate the algae bio factor: prepare 100 one, kg capacity white plastic bucket or transparent plastic bags, get fresh cow dung 30 kilograms, chicken manure 5 kilograms, complex micro organism fungicide 3 kilograms, 0.5 kilogram, brown sugar, add water 40 kilograms, sealing sunlight bottom fermentation 3 days, when temperature is high, sunny, fermentation is hurry up, otherwise more slowly, notice that airtight container will leave sufficient space, otherwise round can be risen brokenly; After fermentation, filter with 120 eye mesh screens, cow dung fiber is removed, Wei Shengwupeiyangshui after filtration evenly splashes in the water surface by 40 kilograms every mu, and Main Function cultivates algae phase, and the feature playing algae is that water colour is vivid light green, transparent cool and refreshing air, ph value 6-8, the most applicable temperature about 25 degree;
The cultivation of algae is the basis of doing water, algae is not only rich in the protein of 50-60%, the fat of about 10%, rational amino acid ligand ratio, the unsaturated fatty acid required for loach growth and vitamin etc., but also be for cultivating or the primary condition of the animality biological feed such as wheel animalcule, cladocera, copepoda in hot housing breeding water body, algae is under photosynthesis simultaneously, release oxygen, and absorb eutrophy composition in water, play the effect purified water.
Cultivate aquatic bait: biological algae water is the prerequisite of culture of living feeds, culture of living feeds is again the important step of loach breeding.After aqueous phase plays algae, just can set about cultivating biological feed.Biological feed refers to after manually cultivating, and the living bait eaten to loach of throwing something and feeding, primarily of animality biological feed compositions such as wheel animalcule, cladocera, copepoda.It is the best opening material of the fry young, is also the key affecting loach larva survive ratio.In natural culture pond, biological feed and water symbiosis, but content is very low, can not meet the needs to biological feed, and for this reason easier method is:
Get each two groups of the silver carp 3-4 of about 1 kilogram, be placed in 20 kilograms of complex micro organism fungicides and soak 2, fish protein is undecomposed, take out and be contained in mesh bag, and diagonal angle is placed on pond, can turn out large number of biological bait after 7 days; The standard of gathering is, every about 10, order under microscope, visually observe 500 milliliters of measuring cups and have 15-20, the method of gathering is, lay floating pump one on one jiao, the native pool; establish 200 order nylon to block two in 120 degree of angles before floating pump, arrange 15 meters long after floating pump, diameter 30 centimeter of 200 order biological feed receives one, worm net; Within 1 hour, biological feed 5-8 kilograms can be gathered in the crops under normal circumstances, under beating oxygen situation after these biological feed water outlets, 5 hours can be survived, the local distance needs to biological feed can be met.
Step 2, fish fry mark seedling:
Also claim spray at the so-called fish fry of aquaculture, the general reference fry young, from spawning and hatching to formation fish fry about about 5 days, is the commodity seeding stage from fish fry to 3.5 centimeters of Changyu bodies, about needs about 20 days under normal circumstances.Wherein about 10 days time be cun seedling stage, the most key, person consumption seedling stage.Period confesses alimentary egg flavine totally in fish carcass, and fish body will be looked for food at natural world voluntarily, finds opening material.In natural environment, high-density breeding loach cannot meet under ecotope biological feed demand at all, people start with artitificial food as prawn slice, egg yolk, eel powder, mixed feed etc., and what have also splashes in seedling pond with soya-bean milk, its result not very people's wills.Over 2 years, the present inventor adheres to feeding with biological feed, obtains outstanding effect.
One is throw something and feed for 2-3 times in loach seedling culturing pool every day by the biological feed of gathering, supply young living bait; Two is the trophisms giving full play to photosynthetic bacteria: by photosynthetic bacteria bacterium liquid with 1%-5% water body proportioning to throw something and feed the young, a young cun seedling nurturing period can be made to shorten to 7 days by 10 days, and growth of seedling is to more than 3.5 centimeters, and larva survive ratio reaches 92%;
Step 3, spice are fed:
Former 60 centimeters of pond waters are filled into 90 centimeters, to throw before seedling 5-7 days, first throw in complex micro organism fungicide and photosynthetic bacteria, ratio is 2:1, consumption every mu 20:10 kilogram, throw seedling and add complex micro organism fungicide the same day, throw in microbial inoculum region corresponding with throwing seedling place, this is because loach seedling can produce collision and scratch in transport packing, and composite microbial bacteria has anti-inflammatory and skin repair effect, seedling also has because the stress reaction first ring change border a few days is not from the feature of original position simultaneously, throw seedling and within second day, press normal artificial forage feed, get complex micro organism fungicide 2% to stir with feed mixed proportion, because feed is dry shape particulate material, in advance microbial inoculum to be annotated pond water when microbial inoculum stirs with material, and then mix with feed, microbial inoculum batch mixing evenly and can be impregnated in feed completely, mixing time controls before nursing, be no less than 30 minutes, feeds 2 every day, morning and afternoon 9 every day and 4 each once, the Main Function of use complex micro organism fungicide is: after complex microbial community enters fish body digestive tract, surely grow at enteron aisle rapidly with the useful bacterial strain of advantage, Tiny ecosystem in fish body is made to maintain balance on the one hand, resist adventitious viruses on the other hand to infect, strengthen antibody, play the effect that early stage strong sprout, mid-term disease-resistant, later stage fattens.Again because bacterium liquid itself has stronger wine flavour, very agreeable to the taste after spice, significantly improve feed conversion rate.
Step 4, water quality improvement: due to loach breeding, to compare the shrimp culture cycle long, add difficulty therefore to the management of water quality.At present, aquaculture controls water quality with chemobiotic medicine per family, brings high risks undoubtedly to healthy aquaculture.The loach breeding cycle is divided into three section type by the present invention: in earlier stage, mid-term and later stage;
Early stage be Seedling Stage, and temperature is not high, and the little input feed of seedling is few, and fish excreta is few, and water quality relatively better, now mainly safeguards water body based on photosynthetic bacteria, and the every 10 days waters surface are splashed a photosynthetic bacteria, mu consumption 10 kilograms;
Mid-term, temperature increased gradually, nursery fast growth, and appetite increases, and the various microorganism of water body also accelerates breeding, and fish body excreta sinks at the bottom of the pool with the residual bait do not eaten up, and started fermentation, and water quality moves towards management difficulty; Complex micro organism fungicide and photosynthetic bacteria liquid are used simultaneously, two bacterium ratio photosynthetic bacterias: composite microbial bacteria is 2:1, also can be used alternatingly by two bacterium, within every 15 days, be watered and evenly splash the water surface once, when being used alone composite microbial bacteria, after throwing in 24 hours, thickness pollutant corrupt at the bottom of the pool can be got to the water surface, should it be skimmed with screen cloth in lower air port in time, being conducive to the end changes;
Later stage temperature raises, temperature can reach 35 degree, fish body has started to grow up, and appetite increases, various microorganism amount reproduction, the excreta of residual bait and fish precipitates accumulation at the bottom of the pool, water quality starts to get worse, and some fish pond occurs blue-green algae, if process not in time because of eutrophy water quality in addition, can turn black at the bottom of the pool fouling, ammonia nitrogen and nitrite very easily exceed standard; Simultaneously, the common disease such as fish body bubble, gill rot, parasite, rotten tail, skin starts to occur, at this moment except normal use complex micro organism fungicide and photosynthetic bacteria liquid, also will increase biological water-bed modifying agent, described biological water-bed modifying agent is the mixture of bacillus licheniformis and zeolite powder, evenly throws in the water surface, sink to after at the bottom of the pool and can deodorizing detoxify, again because it has stronger protease, lipase and diastatic activity, promote the degraded of the residual bait nutrient of feed, and strengthen fish body immunity; But notice that this bacterium has stronger oxygen consumption effect, during use, avoid using when weather is sultry, in case reduce water body dissolved oxygen amount; Answer more options fine, throw in during some gentle breeze, throw in after terminating, open aerator better effects if; If blue-green algae appears in pond, also can select bacillus subtilis, mixing sodium humate uses, and also has better effects, should avoid using the chemicalss such as copper sulphate, with tamper-proof biomechanism environment.
The loach kind that the present invention breeds, head is large, and color is golden yellow, and build is big and fleshy, and meat is plump, and particularly growth is fast, and the culture-cycle is short, and general 6-8 months monomer loach are heavy reaches 2-3 liang, high financial profit, the dark welcome by raiser.
In a word, the present invention adopts microorganism cultivation method, select the effective microorganism preparation of independent research, mainly contain lactic acid bacteria, saccharomycete, actinomycetes and bacillus etc., whole-process control is carried out to culture-cycle ecotope, is mainly reflected in pond and does the primary biological sport technique segments such as water, fish fry mark seedling, spice nursing, water quality improvement.Adhere to control of microorganisms in cultivation, substitute chemicals with effective microorganism preparation, this adheres to that not medication succeeds, also for loach ecologic breeding has walked out the first step under the aquaculture overall background condition of high density, heavy medicine.
