Description
Technical field
The present invention relates to aquaculture technical field, especially a kind of artificial breeding of Penaeus vannamei method.
Background technique
For Penaeus Vannmei adult longest up to 24cm, crust is relatively thin, and normal body colour is shallow cinerous, and whole body does not have speckle.
Step is often in chalk shape, therefore has the title of white limb shrimp.It is wide warm eurysalinity torrid zone shrimps.
Penaeus Vannmei is the highest shrimp species of single rate in three big cultured prawns.It is mainly distributed on US West Pacific Ocean edge
Bank tropical waters, from the Gulf of Mexico to Peru, middle part is all distributed, and is more concentrated with the sea area near Ecuador, is that the world is supported
Grow one of big excellent variety of yield highest three.Penaeus Vannmei shell is relatively thin, and normal body colour is cyanic colours, and whole body does not have speckle,
Form is similar to Chinese prawn (Penaeus chinensis)；Naturally the sea area in depth of water 0-70m is inhabited, belongs to omnivorousness, has
Adaptable, the three big features such as the speed of growth is fast, disease resistance is strong, can give birth to as long as protein rate in bait accounts for 20% or more
It is long；Its delicious meat, dressing percentage are high, eurysalinity, high temperature resistant, and the thin body fertilizer of Penaeus Vannmei shell, delicious meat, dressed fish is high, battalion
It supports abundant.However cultured prawn technology domestic at present, it is not appropriate for culture of Penaeus vannamei, even if cultivation comes out, South America is white
Prawn is at covering with, and meat is poor, and problems above just needs to improve traditional Cultivating techniques, thus herein I
Propose a kind of artificial breeding of Penaeus vannamei method, improve the production of salmon.
Summary of the invention
It is biggish to improve Penaeus Vannmei the purpose of the present invention is to provide a kind of artificial breeding of Penaeus vannamei method
Yield.
The present invention is to solve above-mentioned phenomenon, using the technical solution of following modification, a kind of artificial breeding of Penaeus vannamei side
Method, specific artificial breeding include the following steps,
A builds nursery pond, and nursery pond pond shape is preferably rectangle, and pond is 1.5 meters -2 meters deep, and pool wall can use reinforced concrete
Perfusion is applied with cement, non-leakage, do not crack, and 24 centimetres of tank block wall thickness, pond is 36 centimetres thick every brick wall；
B, parent shrimp rearing, selection is physical strong, and weight is used as seed shrimp in 0.25~0.35kg or more, and body is then by seed shrimp
Female-male proportion is put into nursery pond according to 5: 1, and the Suitable Density of parent shrimp rearing is 5~100 tails/m2, water temperature control is 8~17
DEG C, dissolved oxygen 8mg/L or more, 30~50L/s of flow；
C starts the breeding period that mates in seed shrimp, carries out ovum artificial collection, the ovum adopted need to use isotonic solution, they are successively molten
In 10L water, pH value 7, and adjust the temperature to 4 DEG C or more and rinse, the Yolk flowed out in ovum is washed away, and remove excessive
Bad ovum, ovum skin, clot etc. after the complete water swelling of fertilized eggs, then move into incubator and hatch；
D, hatching management should be protected from light ventilation during entire hatching, prevent vibration and mechanical stimulus；Dead ovum is easily grown simultaneously
Unboiled water is mould, therefore needs to arrange to pick ovum operation several times in hatching process；
E puts the seed shrimp after hatching in a suitable place to breed, and pond is put in selection in a suitable place to breed, and the water body of putting in a suitable place to breed is 2.0 meters deep with each Chi Chi,
20~50 cubic metres of water body are advisable；
F, the feeding management of young shrimp and water-changing tube reason.
It further include that antibacterials are added in nursery water, mainly in step b as present invention further optimization mode
Antibacterials include 0.5~1ppm of terramycin, 1~10ppm of chloramphenicol, nitrofurazone 1ppm, 30~200ppm of nystatin, dysentery
Trane 1ppm.
As present invention further optimization mode, the isotonic solution is set as NaCl, KCl, CaCl2Mixture, system
Making ratio is 14:6:1.8.
As present invention further optimization mode, in step f, shrimp seedling is controlled in nauplius stage, water temperature 19.5
Add 10 centimetres of water between~22 DEG C daily simultaneously, after nauplius metamorphosis to zoea, water temperature is gradually by the 22 of one phase of flea shape
28 DEG C of three phase of flea shape DEG C are raised to, when arriving the flea shape second phase, changes water 1/3 or so daily, aeration quantity is increased to fluidized state, and water colour is protected
Yellowish-brown is held, the main bait of this phase has soya-bean milk, and microparticle eats female life and olaquindox, paedomorphosis to flea shape the second stage of later period
When, the tooth worm's ovum of decladding, shellfish ovum and trochophora are put into right amount, and nauplius or the wheel for throwing tooth worm are added by three phase of flea shape
Worm.
As present invention further optimization mode, in step f, shrimp seedling when the young is changed into mysis, feeding habits oneself
Switch to based on animality, this phase should feed the tooth worm young, and the trochophora and tooth worm's ovum of shellfish feed yolk or manually do particle
Bait is removed contamination in time, and daily quantity of exchanged water is deep 1/2 in pond, and water temperature guarantees the method that heating and cooling can be used between 28~30 DEG C
Mysis is stimulated to cast off a skin, the amplitude of heating and cooling is between ± 0.5 DEG C daily, and the young enters post larval, and food ration significantly increases,
Early period son shrimp (phase of P1~2) every tail can throw the tooth worm young 70~100 daily, when tooth children is insufficient, can feed rubbing and clean
Cockles or artificial micro-pellets gradually to cool down daily, daily quantity of exchanged water is no less than 1/2 to young three phase of shrimp.
As present invention further optimization mode, in step e, the method for the shrimp seedling put in a suitable place to breed includes breeding density
150~200 tails/m2, water source is brackish water, water flow velocity 0.15m3/ s, water quality is limpid pollution-free, pH value 7.2, dissolved oxygen 11.5mg/L,
15.5~21.5 DEG C of water temperature；Using at protein feed, the protein content of feed is 40%~45%, wherein animal protein
Matter should not be less than 40%~45%, and day feeds 2-4 times.
Beneficial effects of the present invention are as follows: the present invention improve by the method for artificial propagation the survival rate of juvenile prawn, and
And different cultivations is carried out according to juvenile prawn different times, and the growth rate of juvenile prawn is substantially increased, the Penaeus Vannmei cultivated out,
Meat is delicious, and volume is larger, and protein content is high, and whole breeding method is simply scientific, is worthy to be popularized.
Specific embodiment
