Description

Penaeus Vannmei high-efficient ecological cultivation method
Technical field
The present invention relates to a kind of culture of Penaeus vannamei method.
Background technology
The cultivation of existing South America great Bai shrimp, the defects such as ubiquity survival rate is low, and the culture-cycle is long, require further improvement.
Summary of the invention
The object of the present invention is to provide a kind of survival rate high, easy to operate Penaeus Vannmei high-efficient ecological cultivation method.
Technical solution of the present invention is:
A kind of Penaeus Vannmei high-efficient ecological cultivation method, is characterized in that: comprise the following steps:
(1) cultivation greenhouse is set up
Cultivation base adopts the shale pond of high density temperature canopy intensive culture mode, and bank protection is carried out in pond, and the area of each pool mouth is 4 ~ 6 mu, the depth of water is 1.0m ~ 1.5m, the upper hot house for steel frame construction, has independently irrigation channel, and each growing pond water inlet in base is independent, unimpeded; Draining adopts the mode arranging bottom discharge system, and pool mouth is equipped with oxygen transfer 2 kilowatts/mu;
(2) selection of seed and the preparation before putting in a suitable place to breed
(1) shrimp seedling put in a suitable place to breed before preparation
1. pond disinfection: adopt the bleaching powder of effective chlorine >=28% or sodium dichloro cyanurate to carry out pond disinfection; Every mu, bleaching powder uses 15 kilograms, and be watered the full pool and splash, residue does not sprinkle in pond; Sodium dichloro cyanurate is used 5 kilograms and is watered full pool spilling head;
2. pond water inlet: pond disinfection is after 2 days, before shrimp seedling is put in a suitable place to breed 15 days, with sleeve-like screen filtration water inlet 50 ~ 60cm more than 60 orders, reuse bleaching powder and carry out water body disinfection, concentration was 2mg/kg, the sterilization cultivation underlying biological bait that applies fertilizer afterwards for five days;
3. fertilising training bait: use bio-fertilizer, consumption is 1-2kg/ mu; Also spraying fertilizer, topdress and adopt amino acid rich water element, consumption is at 0.5-1kg/ mu;
(2) shrimp seedling is put in a suitable place to breed: pond depth of water 60cm ~ 80cm, and water temperature more than 22 DEG C carries out putting seedling; Put seedling at late March for first batch, every mu of 80,000 tails; Second time puts seedling in early August, every mu of 100,000 tails; After seed puts 20 days in a suitable place to breed, put into the Silurus Soldatovi Meridionalis of 10-20 tail/mu to pond, the specification of Silurus Soldatovi Meridionalis is 20 tails/kg, or puts into the Pelteobagrus fulvidraco of 15-25 tail/mu, and Pelteobagrus fulvidraco is specification is 20 tails/kg;
(3) feeding and management: it is 3% ~ 8% of shrimp body weight that day throws the rate of raising; Seedling stage dietary protein level 42%, fat content 6-8%; Dietary protein level about 40%, fat content 6-10% after the long 6cm of shrimp body;
(4) water quality management: change water once in 5 ~ 15 days, each quantity of exchanged water, at 5 ~ 8 centimetres, makes breeding water body meet following water quality index: transparency 25cm ~ 40cm, pH value 7.5 ~ 8.6, more than dissolved oxygen 5mg/L, ammonia nitrogen (NH 4-N) below 0.3mg/L, below nitrite 0.05mg/L, sulfide below 0.1mg/L.
The technology of the present invention is advanced and applicable, workable, reduces the cultivation risk of Penaeus Vannmei.Decrease the generation of disease.Improve the dissolved oxygen amount of each water layer in warm canopy, improve the situation of bottom water, be conducive to the appetite increasing Penaeus Vannmei, improve the digestive utilization ratio of feed.Achieve the object reducing costs, increase economic efficiency.During the gap of two generations breeding, by removing the plastic sheeting covering warm canopy, putting at the bottom of the pool, aeration, pond and tanning by the sun, oxidation, can decompose the Eutrophication materials in bed mud in time, has positive role to improvement soil, reparation ecological environment; Also the safety in production of next batch is conducive to.Fishery economic remarkable benefit, mu benefit is turned over.
The present invention be advantageous in that:
1, warm canopy quick heating, the culture-cycle is short, and the whole year can support two batches.
The first half of the year puts seedling in late March ~ early April, the fine day of continuous 2 ~ 3 days, and the water temperature in warm canopy just can rise to more than 28 DEG C, and white shrimp can normally eat food growth, through the cultivation of 60 ~ 70 days, about white shrimp just can reach per kilogram 100 tail.In July then, pond is shone through desilting, Loss-on-drying, and water body disinfection, early August can be thrown again seedling and be carried out second batch of cultivation.
2, adopt bottom oxygenation and bottom blow-down, guarantee cultured output.
Along with the increase of daily ration, feeding quantity, the cumulative deposition of the harmful substance such as ight soil, residual bait, pool bottom environment runs down, and opens bottom discharge system in time, discharges bottom sewage, guarantees to be conducive to white shrimp healthy growth by the bottom environment that pond is good.
3, after booth seedling puts 20 days in a suitable place to breed, Xiang Chizhong puts into appropriate Silurus Soldatovi Meridionalis, for the shrimp seedling of dying of illness of ingesting in pond, prevents germ from working the mischief to health young shrimp.
4, fine day can by the area coverage of the warm canopy film of adjustment, and the water temperature in basic controlling pond remains between 28 ~ 32 DEG C, has both saved the energy, is conducive to again white shrimp and grows fast.
The culture-effect comparison of this patent cultural method and conventional cultivation method
Below in conjunction with embodiment, the invention will be further described.
