Abstract
The invention relates to a giant freshwater prawn breeding method. The giant freshwater prawn breeding method comprises the steps that giant freshwater prawn zoea nauplius larva offspring seeds cast skins eleven times to grow into shrimps with the length of 0.7-1.0cm. According to the giant freshwater prawn breeding method, giant freshwater prawns of a good stock are selected, and the zoea nauplius larva offspring seeds of the giant freshwater prawns are bred and cast skins eleven times to grow into the shrimps with the length of 0.7-1.0cm. By the adoption of the giant freshwater prawn breeding method, the rate of emergency of an offspring seed field is high, good breeding economic benefits are generated, it is guaranteed that the rate of survival of sold shrimps is greatly improved, the bait efficiency is improved, the grown giant freshwater prawns are large in size, delicious and free of pollution, and therefore both production and income of a prawn breeder are increased.
Description
Technical field
The present invention relates to a kind of mating system of fresh water shrimp, relate in particular to a kind of Macrobrachium rosenbergii mating system.
Background technology
Since whole nation outburst Macrobrachium rosenbergii larvae syndrome in 2010, there is childlike phenomenon in the filial generation breeding then in breeding production process, and raiser is referred to as " iron-clad shrimp ", " under long pawl " or " stone shrimp ".Be that juvenile prawn grows to 5cm～6cm and just stops growing, but foot of a chela president very long on the contrary, the existence of normally ingesting of this seed shrimp, can be dead, thereby cause the waste of feed, and then cause the decline of output, to raiser, brings serious loss.The appearance of these phenomenons and nursery are not focused on seed shrimp and are cultivated, the good seed shrimp of not seed selection, and drug use is improper or excessive use antibiotic is closely related.
Numerous studies have shown that, it is the important source of infection that parent shrimp is carried virus, with the trans-regional transportation of viral seed and the use of seed culture of viruses shrimp in spite of illness, close shrimp difficult quality is controlled, cause growing seedlings in producing and occur the problems such as lethality is high, the differentiation of larval growth speed is serious, cause the breeding coverage rate in Macrobrachium rosenbergii breeding production low, seriously hindered the sound development of Macrobrachium rosenbergii aquaculture industry, germplasm is degenerated has become the bottleneck of restriction Macrobrachium rosenbergii industry sustainable development, perplex vast Macrobrachium rosenbergii raiser, affecting the steady and sound development of Macrobrachium rosenbergii aquaculture.These phenomenons are with part nursery seedling growing process is lack of standardization closely related at present.Some nurseries are profit-push, generally adopt high temperature to grow seedlings, and in seed produces, use forbidden drug, parent are strictly selected, more without selected technology standard.
In brief, Macrobrachium rosenbergii mating system is science not, can cause nursery emergence rate low, the shrimp seedling of selling away, and lethality is high, and not dead is also childlike, causes shrimp agriculture underproduction loss of capital.
Summary of the invention
The present invention provides the Macrobrachium rosenbergii that a kind of emergence rate is high, survival rate is large, feed efficiency is high, stature is large, increase economic efficiency mating system in order to overcome the above problems.
Technical scheme of the present invention is: this mating system comprises that Macrobrachium rosenbergii flea shape nauplius seed, through 11 decortications, grows up to the process of 0.7～1.0cm shrimp seedling, specifically comprises the harmless processing of breeding pond before Macrobrachium rosenbergii seed breeds; Simulated seawater preparation; The harmless processing of fresh water before simulated seawater preparation; Harmless processing after simulated seawater preparation; Seed enters physical property buffering temperature differential method, the water environment difference buffer method of breeding pond to breeding field; The bait of breeding the stage regulates method; Breed the management in pond; And the temperature adjusting of breeding rear desalination process.
Described harmless processing of breeding pond will be bred pond and will be constructed to east-westly, and each pool area is about 11.5m
2; Breed on the ceiling above pond, be provided with packaged type black sun-shading mesh, corresponding light source is also set, during can making to breed, intensity of illumination is controlled at 2000LX; Breeding pond sterilizes with the lime water of high temperature before use; Alternately sterilizing with mist formula disinfectant or ultraviolet ray in the whole space, chamber of breeding, within 7-10 days before breeding, completes.
The Main Ingredients and Appearance of described simulated seawater preparation comprises NaCl, MgSO
4, CaCl
2, KCl, NaBr, H
3bO
3, Na
2siO
3, Al
2cl
6, each component content ratio is: 26553:3252:1651:713:51:57:41:13.
Described physical property buffering temperature differential method, water environment difference buffer method are by the flea shape nauplius seed oxygen bag of transporting to, by quantity, first directly put into the pond of breeding separately, Macrobrachium rosenbergii flea shape nauplius seed (ten thousand tails) with breed pond area (square metre) ratio: 10:1 to 10.5:1, after 2 hours, then open bag; While opening bag, level slowly to open, allow Macrobrachium rosenbergii flea shape nauplius seed slowly swim voluntarily to breeding in pond, this process is 0.5～1 hour, and the last horizontal back curve of elder generation gently is upwards mentioned bag.
Described bait adjusting method of breeding the stage comprises first uses palatability biological feed fairy shrimp, throws something and feeds; After within 7 days or 4-5 time, peeling, the egg root of throwing something and feeding; After 11 days, the agreeable to the taste micro-material bait of the Combination of throwing something and feeding.
Described management of breeding pond comprises the management of water temperature, dissolved oxygen, water quality, illumination and water flow velocity, and described water temperature is controlled at 27-28 ℃; Dissolved oxygen is controlled at 6.0～6.9ppm; Water quality is mainly salinity and ammonia-nitrogen content, and salinity is controlled at 8～9%, and ammonia control is below 0.1ppm; Illumination is controlled at 2000LX left and right; The flow control of water is at 10-15m/ hour; Macrobrachium rosenbergii flea shape nauplius seed, through after 11 days breed, remove pond, adds water and after 20%, 17 day, change water and after 40%, 18 day, change water 50% after 15 days.
Described temperature adjusting of breeding rear desalination process is in Macrobrachium rosenbergii flea shape nauplius seed, through 19 days breed or completed after the decortication of 10-11 time and operate and carry out, the fresh water carrying out during desalination does not need sterilization, filtration, dosing and heat treatment, directly from sedimentation basin, aspirate, give to deliver to and breed pond; Now will control temperature: temperature remains on 27-28 ℃, the temperature difference is less than 0.5 ℃/h, notes the balance of Inlet and outlet water simultaneously, finally realizes salinity below 2 ‰, and this process is about 2 days, and the water temperature after desalination should be 26 ℃～27 ℃.
The present invention includes the Macrobrachium rosenbergii of selecting improved seeds, cultivate this seed and peel through 11 times from flea shape nauplius, grow up to the process of 0.7～1.0cm shrimp seedling, realize nursery emergence rate high, produce the good economic benefit of breeding; Can guarantee the shrimp seedling of selling away, survival rate improves greatly, and bait efficiency improves, and grows up to stature large, and the nuisanceless Roche of delicious flavour becomes shrimp, makes shrimp agriculture increasing both production and income.
