Abstract
The invention provides a method for cultivating shrimp seeds of macrobrachium rosenbergii. The method comprises: selection and processing of a parent shrimp holding pond, selection of a parent shrimp, feeding pretreatment of the parent shrimp, feeding of the parent shrimp, requirements on a nursery pond, water conditioning of the nursery pond, observation of parent shrimp mating, cultivation of larva, daily management of the nursery pond and other contents. In the water conditioning, an environment-friendly Chinese herbal medicine powder fungicide is adopted to treat the water source, so that the morbidity of the parent shrimp and the seedlings is reduced. The shrimp seed individuals cultivated according to the method of the invention has small difference and good quality. Moreover, a high survival rate of the shrimp seeds is obtained, so that the economic benefit of culturists is improved.
Description
Technical field
The present invention relates generally to the method for shrimps genetic breeding., particularly relate to a kind of breeding method of Macrobrachium rosenbergii shrimp seedling.
background technology:
macrobrachium rosenbergii also claims white pin shrimp, Malaysian prawn, money shrimp, Penaeus vannamei etc., have fresh water shrimp king's title.Original producton location concentrates on Ecuador bank, is one of three large shrimp species that cultivation amount is in the world the highest at present.The thin body fertilizer of its shell, Fresh & Tender in Texture, delicious flavour, nutritious.Except being rich in the local flavor of general Freshwater shrimps, in ripe Macrobrachium rosenbergii carapace, be full of gonad, there is the taste of the special deliciousness that is similar to crab oil.Every hectogram shrimp shrimp is containing 20.6 grams, protein, 0.7 gram, fat, and contain multivitamin and the necessary trace element of human body, be high-protein nutrient aquatic products, it is the main Freshwater shrimps kind of current China cultivation, the shrimp seedling great majority of Macrobrachium rosenbergii are that Tu Chi cultivates at present, cause shrimp seedling emergence rate low, and quality is unstable, in process of growth, survive rate variance, problem that growth rate is slow etc., therefore, in the urgent need to a kind of new Macrobrachium rosenbergii factorial seedling growth mode.
summary of the invention:
The invention provides a kind of breeding method of Macrobrachium rosenbergii shrimp seedling, the inventive method has overcome that the shrimp seedling emergence rate existing in existing breeding method is low, and quality is unstable, and in process of growth, survival rate is not high, the defect that growth rate is slow.
The present invention adopts following technical scheme for achieving the above object:

(2) close shrimp is chosen: select size in different water systems even, energetic, healthy female, male shrimp is as close shrimp, more than the long 3.5cm of female shrimp body; More than the long 4cm of male shrimp body;
(3) the raising pretreatment of close shrimp: female, the male shrimp of the same water system that step (2) is chosen separately, then, by the female shrimp of different water systems and male shrimp, is put into same brackish water pond and raises;
(4) close shrimp is raised: every morning and afternoon respectively throw something and feed once, and the manufactured feed of throwing something and feeding the morning accounts for the 2-3% that raises close shrimp body weight, and the fresh small fish of throwing something and feeding afternoon accounts for the 2-3% that raises close shrimp body weight; In pond, add fresh water 30-50m every day
3;
(5) nursery pond requires: select the indoor cement pit of 4m × 5m × 1.2m as nursery pond, lay gas stone in pond, gas stone density is 9-11/m2, and nursery pond top covers movably puggaree, for regulating illumination;
(6) nursery pond water quality processing: grow seedlings before beginning, need sterilize thoroughly to nursery pond, will be after 80 order nets, pass through again fine sand, then in water, add 3 kilograms/100L of pulverizing Chinese medicine material insecticide 0.2-0., the part by weight of the raw material components of traditional Chinese medicine insecticide is: david poplar root-bark 8-10, Chinese wild pepper 8-10, Lindley Butterflybush Herb 8-10, Embelia subcoridcea (C. B. Cl.) Mez 8-10, cassia twig 8-10, windproof 8-10, elscholtiza 8-10, chrysanthemum 8-10, schizonepeta 8-10, purple perilla 8-10, field pennycress 8-10, Sargent gloryvine 8-10, Radix Isatidis 8-10, Herba Andrographitis 8-10, rhizoma zingiberis 8-10, mulberry leaf 8-10, kuh-seng 8-10, the old 8-10 of bacterium, rheum officinale 8-10, loguat leaf 8-10, print chinaberry fruit 8-10, Chinese violet 8-10, folium isatidis 8-10, tarragon 8-10, juglandis folia 8-10, frutus cnidii 8-10, tuber of stemona 8-10, rhizome of cyrtomium 8-10, soak after 3-4 hour, use again activated carbon filtration, relief disinfectant enters the nursery pond of sterilizing, water level is used 30 milliliters/meter after reaching requirement again
3formalin is processed water for larval nursing 22-26 hour, and then aeration 2-3 days, finally adds chitin, makes concentration in its pool water within reach 0.8-1 gram/meter
3,
(7) observe the mating of close shrimp: the mating situation of routine observation brackish water pond Prawn, when after female shrimp oogenesis, check ovum grain developmental state, when ovum grain bleach, move into nursery pond, close shrimp enters before pond with 20 milliliters/meter

test data
The method of the inventive method being cultivated to Macrobrachium rosenbergii shrimp seedling and existing Macrobrachium rosenbergii cultivation shrimp seedling contrasts, and cultivates and the results are shown in following table:
? | Shrimp shoot survival percent | With the individual difference of a collection of shrimp seedling | Sign |
Factory culturing method of the present invention | 90% | Individual difference is little, and quality is good | Shrimp seedling appendage is complete, N/D |
Existing native pond cultivating method | 40% | Individual difference is large, poor quality | Shrimp seedling appendage has damaged |
The inventive method is cultivated shrimp seedling as can be seen from the table, and shrimp shoot survival percent is high, and little with a collection of shrimp seedling individual difference, quality is good, and shrimp seedling appendage is complete, N/D.The survival rate of shrimp seedling brings up to 90% by 40% of traditional seedling rearing in earth ponds, has solved the nonsynchronous problem of the growth of Macrobrachium rosenbergii larvae in seedling rearing in earth ponds simultaneously.
