Description
Technical field
The invention mainly relates to cultural technique field, particularly relate to the high-efficiency breeding method of a kind of Lobster juvenile prawn.
Background technology
At present, in the breeding process of Lobster juvenile prawn, in order to improve survival rate and the growth rate of juvenile prawn, before juvenile prawn is put in a suitable place to breed
Substantial amounts of preparation can be done, the adaptability of itself from water quality to juvenile prawn, but the survival rate of juvenile prawn is the lowest, typically exists
About 60%, it is extremely difficult to 80%, brings the biggest economic loss to peasant household, therefore, the survival rate improving juvenile prawn is current Lobster
Breeding process is needed badly the significant problem of solution.
Summary of the invention
In order to make up the defect of prior art, it is an object of the invention to provide the high-efficiency breeding method of a kind of Lobster juvenile prawn.
The high-efficiency breeding method of a kind of Lobster juvenile prawn, specifically includes following steps:
(1) shrimp pond is built: the Chi Geng in shrimp pond cement is built, and Chi Geng sets up medicine hole, and the mud ridge is set up along Chi Geng, distance Chi Geng
1.6 ~ 1.8m, placing particle diameter in medicine hole is the zeolite of 1.2 ~ 1.4cm, adsorbs noxious substance, cleans water quality；
(2) water sterilization: juvenile prawn is put in a suitable place to breed first 2 ~ 3 days, injects river, the depth of water 0.7 ~ 0.9m, water temperature 28 ~ 30 DEG C, dissolved oxygen in shrimp pond
Amount is 7 ~ 8mg/L, cleans up the pond once every 30 ~ 35 days later, is sprinkled into the dry lime of 22 ~ 24kg/ mu after cleaning up the pond, to dry pool sterilization 20
Being washed on the dry pool after ~ 22 hours, during water filling, aperture is the strainer filtering of 0.2 ~ 0.4cm, is uniformly sprinkled into every 5 days in water
Once sterilizing agent, the amount of being sprinkled into is 10 ~ 12g/ mu, periodically sterilizes, suppression pathogenic microorganism growth；
(3) juvenile prawn is put in a suitable place to breed: select the juvenile prawn of a length of 1.2 ~ 1.4cm, and juvenile prawn specification is consistent, and body constitution is healthy and strong, anosis without wound, puts in a suitable place to breed
Before, take a certain amount of water, be configured to the edible alkali solution that mass fraction is 0.6 ~ 0.8%, juvenile prawn is placed in edible alkali solution
Soaking 6 ~ 8 minutes, take out, put in a suitable place to breed in shrimp pond, breeding density is 1.2 ~ 1.4 ten thousand tails/mu；
(4) throwing something and feeding feedstuff: do not carry out plankton cultivation, from the beginning of juvenile prawn is thrown in, Lobster juvenile prawn of all throwing something and feeding cultivation is special
Mixed feed, throws something and feeds 3 every day, throws something and feeds for the first time: morning 5:30 ~ 6:30, inventory accounts for the 25 ~ 30% of whole day inventory, second
Secondary throw something and feed: afternoon 15:30 ~ 16:30, inventory accounts for the 20 ~ 25% of whole day inventory, and third time is thrown something and fed: night 21:30 ~ 22:30,
Throwing something and feeding remaining whole feedstuff, whole day inventory is the 10 ~ 11% of juvenile prawn body weight, and every natural gift mornings, afternoon and night throw something and feed and raise
Material, meets the growth rhythm of Lobster, promotes growth, saves feedstuff, keeps water cleaning；
(5) daily management: throw something and feed in every morning and afternoon while feedstuff, carry out patrolling the pool, and the shrimp that finds to die of illness to be carried out in time
Cleaning, is down to minimum by loss.
The medicine hole of described step (1), the hole in medicine hole far from 0.4 ~ 0.6m at the bottom of pond, under barrel deviation horizontal alignment 40 ~ 45 °,
Being easy to medicament place, the deep 12 ~ 15cm in hole, be spaced apart 2.2 ~ 2.5m between two holes, aperture, hole is the steel wire of 0.3 ~ 0.5cm
Net covers, and prevents Lobster from entering, it is to avoid medicament is rushed out by water.
The mud ridge of described step (1), builds and adds the Maifanitum soil that mass fraction is 8 ~ 10% in the earth used by the mud ridge,
The particle diameter of Maifanitum soil is 0.6 ~ 0.8cm, reduces the harmful substance in the mud ridge.
The river of described step (2), during injection, first via hole diameter is the strainer filtering of 3 ~ 4mm, then through 5000 ~ 6000 μ W/
cm2Ultra-vioket radiation 25 ~ 30 minutes, last via hole diameter is the strainer filtering of 0.6 ~ 0.8mm.
The disinfectant of described step (2), is made up of the raw material of following weight portion: Cortex Acanthopanacis Radicis 27 ~ 29, Radix Sanguisorbae 27 ~ 29, sugarcane 23
~ 25, Herba Sophorae alopecuroidis 23 ~ 25, Salvia japonica Thunb. 23 ~ 25, Rhizoma polygoni vivipari 20 ~ 22, Herba Galii Teneri 20 ~ 22, Radix Hydrangeae Strigosae 20 ~ 22, Herba Peristrophes 20 ~
22, Symphytum officinale 19 ~ 21, Herba Buddlejae Lindleyanae 19 ~ 21, clean above raw material, pulverizes, and crosses 80 ~ 100 mesh sieves, obtains Chinese medicine powder, adds Chinese medicine
The water of grain weight amount 4 ~ 5 times amount, mix homogeneously, add the cellulase of Chinese medicine powder weight 1 ~ 2%, be placed in 40 ~ 42 DEG C of enzymolysis 90 ~ 100
Minute, after heated and boiled, filtering, obtain filtering residue A and extracting solution A, add the boiled water of filtering residue A weight 10 ~ 12 times amount, 34 ~ 36kHz surpasses
Sound 25 ~ 30 minutes, filters, and obtains filtering residue B and extracting solution B, adds the wine that volume fraction is 67 ~ 69% of filtering residue B weight 8 ~ 10 times amount
Essence solution, in 40 ~ 42 DEG C, ultrasonic 25 ~ 30 minutes of 35 ~ 37kHz, filters, merges all extracting solution, crosses 120 ~ 140 mesh sieves, 80 ~
100m/s is spray-dried, and obtains disinfectant.
The mixed feed of described step (3), protein content is 22 ~ 24%, and zinc content is 10 ~ 12mg/100g, selenium content
It is 11 ~ 13 μ g/100g, without any hormone and antibiotic, it is ensured that juvenile prawn takes in the nutrition of equilibrium, strengthens resistance against diseases.
The invention have the advantage that the high-efficiency breeding method of a kind of Lobster juvenile prawn that the present invention provides, it is possible to strengthen juvenile prawn and exempt from
Epidemic disease power, prevalence is down to 3%, survival rate 92%；From shrimp pond build, water sterilization, juvenile prawn put in a suitable place to breed, feedstuff of throwing something and feeding, daily management
Five aspects carry out comprehensive control, and shrimp pond is provided with medicine hole, place zeolite, add Maifanitum soil, it is possible to absorbing toxin, cleaning in the mud ridge
Water quality, cleans up the pond within the set time and sterilizes, and thoroughly kills pathogenic bacteria, and juvenile prawn puts prospective adaptation water in a suitable place to breed, and sterile-processed,
Every natural gift are thrown something and fed for 3 times Lobster special feed, do not carry out plankton cultivation, the most efficiently, it is ensured that the proportioning science of juvenile prawn feedstuff,
Promoting juvenile prawn growth promoter, water quality is limpid, suppression pathogenic microorganism breeding, carries out patrolling the pool every day, finds symptom, and early treatment,
Avoiding producing bigger loss, income improves 16.4%.
