Description
Technical field
The present invention relates to a kind of artificial fecundation method of economic freshwater shrimps.
Background technology
Procambius clarkii is commonly called as freshwater crayfish, belongs to Arthropoda Crustacea Malacostraca Decapoda thorn mqb section in classification, belongs to the economic freshwater shrimps, is alien species, originates in North America, and nineteen twenty-nine is introduced into China through Japan.Because Procambius clarkii meat flavour deliciousness, nutritious, the shrimp shell can be used as industrial chemicals, and therefore wild Procambius clarkii is suffered artificial fishing in a large number, and quantity sharply reduces.Wild in recent years Procambius clarkii resource can't satisfy the needs that people produce, live, cultures Procambius clarkii by the method for artificial propagation, and the quantity that increases Procambius clarkii has become common recognition.At present, the Procambius clarkii artificial fecundation method generally includes the mating of the cultivation of close shrimp, close shrimp, the cultivation three big steps of the young.Wherein the breeding method of first step parent shrimp is: adopt 3-5% to disinfect with salt solution, then close shrimp is raised in fresh water until sexual maturity; Second step mating method of close shrimp is: natural mating in former water body, lay eggs, hatch; The 3rd breeding method that goes on foot the young is: execute manure of livestock and poultry fertile and throw something and feed artificial feed, pasture and water in former water body, when treating that the young reaches 3-5 centimetre of specification, become the commercial sized prawn seedling.The characteristics of this artificial fecundation method are that whole reproductive process is finished in same water body, and its advantage is the saving of labor, save time, resource-saving.Its defective is: 1, use 3-5% to disinfect with salt solution, to close shrimp, the close shrimp that the particularly dried up time is long injures bigger; 2, natural mating in fresh water, lay eggs, hatch, the egg laying rate of red swamp of close shrimp is not high; 3, the young of different size and close shrimp are grown in same water body, the rate of killing each other height, and survival rate is low; 4, directly execute the fertile and artificial feed of throwing something and feeding of manure of livestock and poultry during the larval culture in water body, manure of livestock and poultry fertilizer ferments at the bottom, mainly plays rich water, seldom utilized by shrimp, and cause serious water pollution, influenced the feed of Procambius clarkii to normal feed, efficiency of feed utilization reduces greatly.Because the existence of above-mentioned defective causes existing Procambius clarkii artificial fecundation method seedling cost height, of poor benefits.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide a kind of and kill each other, improve a series of measures such as efficiency of feed utilization, the industrial artificial propagation method of the Procambius clarkii of reduce seedling cost, increasing economic efficiency by the injury, raising egg laying rate of red swamp, the minimizing that reduce close shrimp.
Technical solution of the present invention is: the industrial artificial propagation method of a kind of Procambius clarkii comprises mating of the cultivation of close shrimp, close shrimp and the cultivation three big steps of the young.Wherein the step of parent shrimp rearing is: 1. sterilization, and 2. fresh water is supported temporarily; The step of parent's shrimp mating is: 1. the artificial induction, accelerate the ripening, 2. mating, lay eggs; The step of larval culture is: the feed that 1. applies fertilizer, throws something and feeds, 2. larval culture to the III phase is caught out other pond cultivation, when 3. III phase larval culture is to the long 3-5 of body centimetre of specification, becomes the commercial sized prawn seedling.
Described disinfectant method is to use the liquor potassic permanganate of 10-30 mg/litre concentration to soak 5-10 minute.
Described artificial induction's method is to be that the artificial seawater of 0.5-2.0 ‰ or the natural sea-water close shrimp before to mating is induced mating and lays eggs with concentration.
Described method of accelerating the ripening is to remove the optic stalk of close shrimp one side.
The method of described fertilising is to the water body biological organic fertilizer of splashing.
Described to the water body biological organic fertilizer of splashing, its consumption is the 5-30 mg/litre.
Use method provided by the present invention to have following advantage: 1, the liquor potassic permanganate immersion is used in close shrimp sterilization instead, not only can kill the lung fluke and the bacterium that colonize in the Procambius clarkii carapace, and avoided the side that disinfects with salt solution with traditional concentration 3-5%) to the injury of close shrimp, make close shrimp put survival rate in a suitable place to breed and be improved.2, close shrimp mating adopts the artificial seawater or the natural sea-water of low salinity to induce, and the egg laying rate of red swamp of close shrimp is greatly improved than natural mating in fresh water; Excise the one-sided optic stalk of close shrimp and accelerate the ripening, make the X-organ-sinus gland complex in the optic stalk reduce by 50%, accelerated the gonad development of close shrimp the inhibitory action of close shrimp gonad development.3, larval culture is except that the artificial feed of throwing something and feeding, and also to the water body biological organic fertilizer of splashing, this not only can cultivate a large amount of biological feeds, and the probio in the fertilizer can make the water quality of Chi Shui keep benign cycle, improved the availability of feed.4, during the phase young is caught out other pond to III when paedomorphosis in the pond from the breeding pond and cultivate or sell, massacre the generation of little young phenomenon, survival rate of seedling is greatly enhanced to have reduced big specification shrimp seedling.Because this method has above-mentioned four advantages, therefore use this method artificial propagation Procambius clarkii seedling cost low, good in economic efficiency.
