Abstract
The invention relates to a method for cultivating highly-healthy young penaeus vannamei. The method is characterized by comprising the following steps of: establishing a young penaeus vannamei cultivating shed; preparing a cultivating feed: smashing a penaeus vannamei 0# material, and adding compound vitamin & amino acid soluble powder; stocking young penaeus vannamei: before stocking young penaeus vannamei, scattering Sanbao high-stability VC (Vitamin C) into a pond; stocking young penaeus vannamei at the density of 1,000-1,500 young penaeus vannamei per square meter; after stocking young penaeus vannamei, starting a bottom layer automatic aerator, and feeding the cultivating feed; gradually adding water in a shed cultivating period according to the conventional feeding cultivating period, adding Sanbao high-stability VC and rhodop seudanonas palustris every three days, and scattering EM (Effective Microorganisms); disinfecting: disinfecting with Sanbao organic iodine once every week in a young penaeus vannamei cultivating period; and cultivating young penaeus vannamei for 25-30 days till the young penaeus vannamei grow to 8-9 centimeters, wherein the survival rate of young penaeus vannamei is 70-85 percent. Due to the adoption of the method, the survival rate of young penaeus vannamei can be increased, and the cultivated young penaeus vannamei are larger than ordinary young penaeus vannamei.
Description
Technical field
The present invention relates to the breeding method of a seed shrimp seedling, especially a kind of breeding method of high healthy Penaeus Vannmei seedling, belongs to technical field of aquaculture.
Background technology
Penaeus Vannmei Penaeus Vannmei (
penaeus vannamei) formal name used at school is all receives prawn, is wide temperature eurysalinity torrid zone shrimps, belongs to Arthropoda, Crustachia, Decapoda, swimming suborder, originates in waters, pacific rim, South America, is one of three universally acknowledged large good shrimp species.Exactly like Chinese prawn, banana prawn, mean lifetime at least can be over 32 months.The longest 24cm that reaches of adult, crust is thinner, and normal body colour is shallow cinerous, and whole body is not had a speckle.Step is often chalk shape, therefore there is the title of white limb shrimp.The thin body of Penaeus Vannmei shell is fertile, and delicious meat is high, nutritious containing meat rate.
China is since introducing the nineties in last century, and rapidly, cultivation scale and output constantly increase in the cultivation development of Penaeus Vannmei.Particularly in recent years, constantly perfect along with cultural technique and auxiliary facility, the intensive degree of culture of Penaeus vannamei has had large increase.According to the statistics according to Fishery Bureau of the national Ministry of Agriculture, 2007,70.99 ten thousand tons of Chinese seawater culture shrimp output, accounted for 37.6% of Chinese shrimps in culture total amount, and wherein the white shrimp output in South America is 50.99 ten thousand tons, accounts for the total proportion of mariculture shrimp 71.82%.Within 2011, Chinese mariculture prawn output is 89.5 ten thousand tons, and wherein Penaeus Vannmei output accounts for 73%, and export volume is 21.6 ten thousand tons, and export amount is 18.87 hundred million dollars, accounts for 10.6% of aquaculture product export amount, becomes the first kind of product water outlet.China's mariculture Penaeus Vannmei main producing region is in the coastal Guangdong of southern china, Guangxi, Hainan Province.
South America is not low temperature resistant from prawn, and water temperature stops growing during lower than 15 ℃, and in China, In Middle And Lower Reaches of Changjiang River culturing time only had about 4 months.In order to extend the cultivation phase of Penaeus Vannmei, improve Penaeus Vannmei output, we utilize boiler booth temperature control to cultivate juvenile prawn in Penaeus Vannmei pond culture in earlier stage, early numerous shrimp seedling makes its specification reach 6cm left and right through 25-30 days left and right time reinforced cultivatings, put into again pond and cultivate, not only improved shrimp shoot survival percent, for pond high yield is laid a good foundation, and make into shrimp and go on the market in advance, greatly improved culture benefit.But in actual production process, often find that Penaeus Vannmei seedling, in booth cultivating process, puts in a suitable place to breed after 10-20 days, occur large quantities of death.
Summary of the invention
The object of the invention is in order to solve Penaeus Vannmei seedling problem of " difficulty of growing seedlings; Miao Nanyu " during raise seedling in greenhouse, thereby provide a kind of simple and easy to do, can improve Penaeus Vannmei shoot survival percent, and the breeding method of the Penaeus Vannmei seedling of the cultivating a kind of high healthy Penaeus Vannmei seedling larger than common specification.
According to technical scheme provided by the invention, a kind of breeding method of high healthy Penaeus Vannmei seedling, comprises the following steps:
1, build Penaeus Vannmei seedling booth; Build Tu Chi, area 200-300m2, degree of depth 1m, builds booth framework with mao bamboon or steel above, covers plastic film; Coverage of water: 80-100 cube water body; Depth of water 40cm;
2, feed is cultivated in configuration: Penaeus Vannmei 0# material is pulverized, add amino and tie up mend more, per kilogram Penaeus Vannmei 0# material interpolation amino dimension mends 2 grams;
3, put shrimp seedling in a suitable place to breed: put shrimp seedling in a suitable place to breed first 1 hour, the high steady V of the 250g Triratna of first splashing in the pool
c; With 1000-1500 tail/square metre density put shrimp seedling in a suitable place to breed; After throwing in foster shrimp seedling, drive bottom aerator, should continue oxygenation, dissolved oxygen is the most suitable more than 5mg/L; The Penaeus Vannmei 0# that needs to throw something and feed after the foster shrimp seedling of throwing expects, feeding volume 10 grams/ten thousand tail seedlings, and 5-7 days throws something and feeds; The Penaeus Vannmei 0# that throws something and feeds afterwards material, every 1,000,000 tail shrimp seedlings 0# material 3Kg that throws something and feeds, throws something and feeds 2-3 every day;
4, the nurturing period: the booth nurturing period, add gradually water, the 40cm of water level when putting seedling adds gradually and is deep to 60-80cm; Within every three days, throw in the high steady V of Triratna
cand the red spiral shell pseudomonad in marsh, the high steady V of Triratna
cinjected volume is 0.1-0.2g/m
3; Marsh red spiral shell pseudomonad injected volume is 2g/m
3; The every three days EM bacterium of splashing, EM bacterium is 0.12g/m
3;
5, sterilization: during shrimp seed rearing, with the sterilization of Triratna organic iodine once, sterilization amount is 0.045mL/m weekly
3;
6, shrimp seedling is after 25-30 days cultivate, the long 8-9cm of shrimp body, shrimp shoot survival percent: 70%～85%.
Nurturing period shrimp seedling of the present invention shells to reduce and feeds intake; When rainy day, cooling, reduce and feed intake; When water is dense, suitably stop material.
The present invention has the following advantages:
The present invention can improve Penaeus Vannmei shoot survival percent, and the Penaeus Vannmei seedling of cultivating is larger than common specification; Shrimp seedling after 25-30 days cultivate, the long 8-9cm of shrimp body, than the long 6-7cm growth of original body 1-2cm, shrimp shoot survival percent is increased to 70%～85% by original 65%-70%, has improved 15%-20%.
