Abstract
The invention discloses a farming method for improving a prawn survival rate. The method comprises the following steps: fully airing the pond and disinfecting before releasing young prawns, filtering the water source, and fertilizing water; sprinkling high-efficacy EM and beneficial bacteria shrimp seed health medicines during releasing young prawns, wherein the dosage of the high-efficacy EM and beneficial bacteria shrimp seed health medicines is 1 kg per mu; feeding powdery high nutrient feed three times per day during seedling management, quantitatively feeding in fixed time, and observing the feed and prawn body length condition on the stock table; spreading mixed solution of lactic acid bacterial liquid and photosynthetic bacteria liquid into a culture pond according to a dosage of 10 liters per mu in the prawn farming period, keeping 3-7 days, starting a waterwheel aerator every day, starting on each rainy day for 4-5 hours, and starting the aerator on each sunny day for 2-3 hours. Compared with the prior art, the farming method disclosed by the invention has the advantage that the prawn survival rate is greatly improved.
Description
Technical field
The present invention relates to technical field of aquaculture, a kind of cultural method improving prawn survival rate.
Background technology
Prawn, formal name used at school oriental prawn, also known as Chinese prawn, spot joint shrimp.Arthropoda, Crustachia, ten
Foot mesh, Penaeidae, Penaeus.Penaeus is individual big, is generally called prawn.Prawn to pass through in growth course
Tens of times cast off a skin, often sloughs off a skin, just obtains the biggest growth；Casting off a skin is the important of prawn growth
Mark, is directly affected by external environmental condition.Prawn is because the custom of fisherman in history is by " a pair " product pin
Selling calculating and gain the name, be distributed in the littoral shallow water along the coast of seawater water temperature more than 20 DEG C, prawn is extra large shrimp, is me
The special product that state is exclusive, belongs to senior seafood, and the most rare, China's export is earned foreign exchange, and there is now and propagates artificially,
But due to the change of water quality, Dissolved Oxygen in Water gas ability declines, and extreme weather frequently occurs, and the duration is long,
Causing prawn culturing the most difficult, often due to the difference of feeding environment such as at the bottom of water quality and the pool, it is right to easily cause
The problem that shrimp survival rate is the highest.
Summary of the invention
The invention aims to solve the deficiency of prior art problem, it is provided that a kind of prawn survival rate of improving
Cultural method.
For reaching above-mentioned purpose, the present invention implements according to techniques below scheme:
A kind of cultural method improving prawn survival rate, comprises the following steps:
A, the most neutral soil property pool of selection 3-5 mu, be shaped as square circular arc dihedral, be provided with central blow-down system
System, the every 2 mu of waterwheel aerators of aerator, and it is provided with bottom nanometer micropore aerator aeration plate；
B, di-bromonitrilopropiona,ide and water are mixed and made into bactericidal liquid by the weight ratio of 1: 200, use bactericidal liquid
Cleaning culturing pool, after the culturing pool clean water after sterilization, be exposed to the sun 6-10 days, Xiang Chizhong discharges water to water
Face height, when the degree of depth at the bottom of pond being 30-40cm, stops discharging water；
C, in water, uniformly it is sprinkled into primitive ocean crystalline substance salt, makes brine strength at 12%-15%；Shrimp seedling can be improved
Survival rate, the later stage is gradually lowered by salinity, it is possible to heighten the yield of prawn；
D, in culturing pool, it is sprinkled into plant ash 5-6kg/ mu, dregs of linseeds or sesame seeds 1-2kg/ mu, amino acid 0.02-0.03kg/
Mu, guano 2-3kg/ mu, ca and mg fertilizer 0.01-0.015kg/ mu, keep 30-35 days；
E, to sprinkle potent EM and benefit vaccine health medicine when put seedling, potent EM+ benefit vaccine health consumption is
1kg/ mu；
F, select health young shrimp energetic, without pathogenic bacteria, throw in 3-3.5 ten thousand tail prawn seedling for every mu；
G, seedling management, powder of throwing something and feeding height nutrient fodder, every day, breakfast, lunch and dinner, regularly, quantitatively, observed material platform
Material and prawn height situation；Described feed shrimp med, dregs of beans, peanut drum, squid viscera powder, shrimp chaff,
High refined flour, soybean lecithin, fish oil, Choline Chloride, stable vitamin, multidimensional, Duo Kuang, di(2-ethylhexyl)phosphate
Hydrogen calcium, sodium alginate are by 100: 200: 200: 150: 70: 90: 50: 40: 20: 30: 20: 20:
The weight ratio of 30: 30 is mixed；
H, during prawn culturing, in culturing pool, be sprinkled into the mixed liquor of lactobacillus suspension and photosynthetic bacteria liquid,
Consumption is 10 liters/mu, keeps 3-7 days, and every day opens waterwheel aerator, overcast and rainy every day the 4-5 that starts shooting little
Time, start shooting 2-3 hour when becoming a fine day.
As present invention further optimization scheme, described lactic acid bacteria be Lactobacillus plantarum, Lactobacillus casei,
Condense the one or more combination in bud pole bacterium, enterococcus faecalis, VREF.
As present invention further optimization scheme, described photosynthetic bacteria is Rhodopseudomonas palustris, dark red red
The combination of one or more in spirillum, Spherical red antibacterial, capsula Rhodopseudomonas.
Compared with prior art, the present invention fully shines the pool and sterilization before putting seedling, then filters water source, rich water,
Then throw seedling, with potent EM and benefit vaccine health medicine during throwing seedling, can effectively regulate water pH value, eliminate bubble
Foam, survival rate 10%-20% of the raising young, the promotion speed of growth, powder of then throwing something and feeding height nutrient fodder,
Growth can be effectively improved and strengthen spot joint immunologic function；Lactobacillus suspension and the mixed liquor of photosynthetic bacteria liquid,
Due to lactic acid bacteria and the effect of photosynthetic bacteria, it is possible to control eutrophication, change compound microecological system simultaneously
Lactic acid bacteria in agent can also prevent disease, promotes the digestion of gut of shrimp, promotes prawn growth；And it is newborn
The mixed liquor of acid bacterium solution and photosynthetic bacteria liquid can also improve water quality, need not every day during prawn culturing
Change water.Summary, the present invention is greatly improved prawn survival rate.
