Abstract
The invention provides a method for preventing and treating black spermatophore disease of Litopenaeus vannamei, falling into the field of aquaculture disease prevention and treatment. The method is mainly realized through technical measures including aquaculture water treatment, aquaculture environment control, feeding of high-quality baits, drug application and artificial black spermatophore removal by extrusion. The method has convenient application, curative rate up to above 90%, low death rate of male prawn, and no need of cooperation with ripened female prawn. Female prawn ripening and spawning can be performed after re-culture and ripening of diseased male prawn. The method can realize reasonable production arrangement and save production cost.
Description
Technical field
The present invention relates to a kind of sick method of the black spermatophore of Environment of Litopenaeus vannamei Low of preventing and treating, belong to aquatic products disease control field.
Background technology
Black spermatophore disease is meant the spermatophore blackening of the male shrimp of Environment of Litopenaeus vannamei Low, and the sperm fertilizing ability in the spermatophore is low or lose a kind of disease of fertility.After ill, it is poor that the sperm in the black spermatophore is not had fertility or a fertilization ability, causes Environment of Litopenaeus vannamei Low artificial propagation failure.
At present, black spermatophore sick mainly through with the method for the female shrimp mating of maturation, migrate out from spermatophore sac deceiving spermatophore in the male shrimp, form new spermatophore again at spermatophore sac, thereby reach the purpose of control.But this method needs ripe female shrimp to be cooperated; Because sperm fertilizing ability is poor in the black spermatophore, the ovum of output be nonfertilization or fertilization rate extremely low, and male shrimp post-coitum; Again form spermatophore and need the 8d left and right sides time to maturation; During this period, ripe 1-2 time of female shrimp possibility has been wasted the ovum that female shrimp produced; Incur loss through delay the production time simultaneously, consumed water power, manpower, the energy (heating) etc., improved production cost greatly.Therefore, need not use under the prerequisite of the female shrimp of accelerating the ripening, the male shrimp that suffers from black spermatophore is being cured, could guarantee carrying out smoothly of artificial propagation, practice thrift cost.
Summary of the invention
The objective of the invention is to have expensive deficiency to the generality and the sick existing method of preventing and treating of the black spermatophore of Environment of Litopenaeus vannamei Low of the sick morbidity of the black spermatophore of Environment of Litopenaeus vannamei Low; Provide a kind of through handle to cultivate water, control nurturing an environment, the high-quality of throwing something and feeding bait; Drug administration and the artificial comprehensive technical measure of extruding black spermatophore are prevented and treated the sick method of the black spermatophore of Environment of Litopenaeus vannamei Low.
In order to address the above problem; The technical scheme that the present invention adopted is following: a kind of sick method of the black spermatophore of Environment of Litopenaeus vannamei Low of preventing and treating comprises following technical measures: handle and cultivate water, control nurturing an environment, the high-quality of throwing something and feeding bait, drug administration and manual work extrude black spermatophore.
The method that water is cultivated in said processing is: extract the natural waters seawater, the natural waters seawater is used further to suffer from the cultivation of the sick Environment of Litopenaeus vannamei Low of black spermatophore after through the husky filter of one-level, chlorine-containing disinfectant sterilization, the husky filter of secondary.
The method of said control nurturing an environment is: keep salinity 28-35, illumination 200-500lx, pH are 7.9-8.2, water temperature 28-29 ℃; Total ammonia nitrogen < 0.5 mg/>L, nitrite nitrogen < 0.1 mg/>L.
Said high-quality bait be in four types of clam worm, shellfish, squid and the swimming crabs more than 3 kinds or 3 kinds; Feeding method is: the above-mentioned high-quality bait that will choose every day is thrown something and fed once for every kind; Wherein the clam worm feeding volume accounts for 30% of total feeding volume, and the bait of all the other kinds accounts for 70% of total feeding volume.
The method of said drug administration is: at the bottom of the pond, pond is cultivated in cleaning with soil pick-up, change water after the chlorine dioxide 1-1.5mL/m of application concentration 5% in cultivating water body immediately
3, after the chlorine dioxide 6h of application concentration 5%, in cultivating water body, use Norfloxacin 2 mg/L again; The chlorine dioxide of concentration 5% is used once every other day, and continuous administration 7-10 days, Norfloxacin was used once every day, and continuous administration 7-10 days, said two kinds of medicines were when using on the same day, and must be 6h blanking time.
Said manual work is extruded black spermatophore and is meant: when cultivate water through handling, control nurturing an environment, the high-quality of throwing something and feeding bait, four kinds of technical measures of drug administration handles; Also there is the black spermatophore Environment of Litopenaeus vannamei Low of not curing; Then by hand method or electric shocking method extruded its black spermatophore; The Environment of Litopenaeus vannamei Low behind the black spermatophore is extruded in acquisition; By handle cultivating water, controlling nurturing an environment, after the technical measures of the high-quality of throwing something and feeding bait handle, the Environment of Litopenaeus vannamei Low of extruding behind the black spermatophore cultivated, formed the high spermatophore of sperm quality again through 7-10 days again.
Said chlorine-containing disinfectant is a kind of in clorox, chloride of lime, calcium hypochlorite, the sodium trichloro-isocyanurate.
Said clam worm is multiple tooth clam worm or the perinereis aibihitensis Grube of enclosing, and said shellfish is pleat oyster or Ruditapes philippinarum.
Manual work according to the invention is extruded black spermatophore and is meant that manual method or electric shocking method extrude black spermatophore.Manual method is extruded black spermatophore method: 2 people operation, and a people puts on cotton gloves, catches the disease shrimp, exposes the spermatophore position, and another human thumb will be deceived spermatophore and from gonopore, released gently; Electric shocking method takes out black spermatophore method: prepare one of charger; Call in the test test pencil that two red-black universal meters are used, be linked on the charger both positive and negative polarity, be transferred to 3A and 4V to current/voltage; The negative pole pen is placed on abdominal ganglion; Anodal pen is placed on the below of black spermatophore, shocks by electricity 1-2 second, and black spermatophore is gone out from gonopore; If black spermatophore is not hit, available manual method will be deceived spermatophore and released gently.
It is sick that the present invention is used to prevent and treat the black spermatophore of Environment of Litopenaeus vannamei Low, but inapplicable to black spermatophore downright bad, that form lump.
The present invention with respect to the beneficial effect of prior art is: the method convenient in application of preventing and treating of the present invention; The sick cure rate of the black spermatophore of Environment of Litopenaeus vannamei Low is reached more than 90%; Male shrimp lethality is low, does not need ripe female shrimp to cooperate, and can the male shrimp of deceiving spermatophore be cultivated maturation again and carry out the cultivation of accelerating the ripening of female shrimp again; The method of preventing and treating of the present invention can realize the reasonable arrangement to producing simultaneously, saves production cost.
