Description
Technical field
The present invention relates to a kind of lead and cadnium seed good quality and high output mating system, belong to technical field of aquaculture.
Background technology
Lead and cadnium, has another name called cray, is the crayfish the widest, cultivation is the most general that distributes in the world.This shrimp delicious, unique flavor, nutritious, high protein, low fat, is rich in calcium, phosphorus, iron etc., has become the ticbit on urban and rural residents' dining table, is day by day subject to domestic and international market favor, one of main aquatic products that Ye Shi China exported goods and earned foreign currency in recent years.The discovery that lead and cadnium is worth, lures that people fish in a large number into, causes wild lead and cadnium resource day by day exhausted.Increasing raiser starts to propagate lead and cadnium artificially now; but because artificial propagation techniques is immature, cause that the seedling cultivated is unstable and output is lower, supply falls short of demand to make seedling; lead and cadnium large-scale cultivation cannot be realized, have impact on the development of lead and cadnium industry.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of lead and cadnium seed good quality and high output mating system is provided, improve the Quality and yield of shrimp seedling, for lead and cadnium large-scale cultivation provides a good technical foundation.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of lead and cadnium seed good quality and high output mating system, comprises the following steps:
(1) close shrimp is selected
Parent shrimp requires that appendage is complete, and vivaciously healthy and strong, body colour is bright-coloured, glossy, and physique is healthy and strong, and gonad development is good, body weight 35-50g, the long 7-8.5cm of body;
(2) close shrimp reinforced cultivating
Close shrimp is dropped in the cultivation pond of being stamped puggaree the reinforced cultivating carried out 1 month by a definite date, nurturing period regularly sterilizes 2-3 time to cultivation pond with disinfectant, disinfectant consumption is 5-10g/m3, and every day, 17:00 to throw something and feed meat grain feed by the 2-4% of close shrimp body weight, every day, 19:00 washed by water once to close shrimp, and every 4-6 days changes water once, and each quantity of exchanged water is the 1/3-1/2 of the pond depth of water, parent shrimp to be put in the ratio of male and female 2-3:1 after stablizing and breeds pond, strengthens daily management;
(3) daily management
1. water quality management
Every day, 19:00-7:00 established aerator newly, ensured that in water body, dissolved oxygen is sufficient; 5-7 days every day changed water once to pond, and each quantity of exchanged water is the 1/3-1/2 of the pond depth of water;
2. water temperature management
Water temperature 19-31.5 DEG C, day water temperature 19-29.1 DEG C, average temperature 24.5 DEG C;
3. plant disease management
Every 10-15 days with disinfectant to breeding pond disinfection once, disinfectant consumption is 10-15g/m3;
4. pasture and water and cave are arranged
Arrange weter hyacinth or water peanut pasture and water, pasture and water area coverage accounts for 2/3 of water body, breeds period, every 3-5 days inspection once, keep pasture and water area coverages be pond 2/3, go few benefit more; Arrange asbestos shingle cave, the asbestos shingle of 3 pieces of 60m × 70m is settled in each pond, and cave height is 5-6cm, and asbestos shingle arrangement mode is sunflower type, and space is left as feeding point in center;
5. to throw something and feed management
Every day, 17:00 threw something and fed meat grain feed, and feeding volume accounts for the 3-5% of whole shrimp body weight, and each pond adopts 4 fixed points to throw something and feed method, and namely asbestos shingle center slot is a bit, and other 3 is the outer rim of every block asbestos shingle, requires that feed is stolen at the bottom of pond.
The preparation method of described disinfectant is as follows: a, take the raw material of following weight portion: the withered powder 10-15 of rhizome of cyrtomium 2-4, Inula britannica chinensis 1.5-2.5, gall nut 3-5, calamus 1-2, coptis 2-3, leaf of Chinese ilex 1.5-2.5, Herba Andrographitis 2-3, castor bean leaf 2.5-4.5, wolf's milk 1-2, Chinese tallowtree leaf 2-3, pulverized limestone 15-20, tea, crab shell powder 5-10; B, get rhizome of cyrtomium, Inula britannica chinensis, gall nut, calamus, the coptis, leaf of Chinese ilex, Herba Andrographitis, castor bean leaf, wolf's milk, Chinese tallowtree leaf mix, add 5-10 times of water gaging, micro-boiling decocts 1-2h, filter, filter residue adds 4-8 times of water gaging again, and micro-boiling decocts extraction 0.5-1h, filter, be concentrated into appropriate, freeze drying powdered, then mixes with pulverized limestone, the withered powder of tea, crab shell powder.
The preparation method of described meat grain feed is as follows: a, take the raw material of following weight portion: flesh of fish 40-60, freshwater mussel meat 30-50, earthworm powder 15-20, snail powder 10-15, soyabean protein powder 5-10, rice wine grain 4-8, residue of monosodium glutamate 3-6, beet pulp 2.5-4.5, limonite 3-5, medical stone 2-4, asafoetide 1-2, Fructus Hordei Germinatus 2-3, stevia rebaudian leaf 3-4, daghestan sweetclover herb 1.5-2.5, dried orange peel 2-3, sorrel 1-2, Chinese hawthorn root 2-3, anise 1.5-2.5, cape jasmine 1-2; B, get limonite and medical stone mixes, putting into concentration is that the acetum of 10-15% soaks 1-2h, and filter, mixes after drying with rice wine grain, residue of monosodium glutamate, beet pulp, pulverizing, sieves, stand-by; C, get asafoetide, Fructus Hordei Germinatus, stevia rebaudian leaf, daghestan sweetclover herb, dried orange peel, sorrel, Chinese hawthorn root, anise, cape jasmine mix and be ground into meal, add 4-6 times of water gaging, 1-2h is extracted in distillation, and collect distillate, namely centrifugation obtains volatile oil; Then get the dregs of a decoction slow fire boiling twice after distillation, first time adds 8-12 times of water gaging, and second time adds 5-10 times of water gaging, filters, merges twice filtrate, is concentrated into appropriate, the concentrate obtained and volatile oil is merged, stand-by; D, the flesh of fish and freshwater mussel meat put into after meat grinder slightly twists, meat mincing are dropped in cutmixer, add the mixed liquor that step c is obtained again, cut and mix rotten shape, then the powder that earthworm powder, snail powder, soyabean protein powder and step b are obtained is added in meat gruel knead, make it be uniformly dispersed, then granulate, 85-95 DEG C of baking 2-3h, often, meat grain moisture is made to control, at 2-4%, to be cooled to normal temperature.
Beneficial effect of the present invention:
The present invention, by adopting the measures such as water temperature management, water quality adjustment, feed enhancement, Improvement of Ecological Environment, impels lead and cadnium sexual gland synchronously to grow, and induction lead and cadnium synchronous spawning, reaches biological control, improve the object of seedling output; Reserved and the strange land male and female proportioning by rational high-quality population, the merit of Optimal culture shrimp, is formed and is applicable to zonal lead and cadnium high-quality seed standardization raising technology.5 mu of lead and cadnium seed breeding bases can reach the ability of more than juvenile prawn 1,500,000 tail producing 1-2cm per year, and the juvenile prawn produced can meet 100 mu of pond cultures.
