Abstract
The invention discloses a biological prevention and control method for controlling prawn diseases through grass carps. In the method disclosed by the invention, grass carps are thrown in prawn culture zones, thereby realizing the prevention of communicable diseases of prawns and improving the survival rate of the prawns. The method disclosed by the invention can avoid propagation and spread of prawn diseases in healthy prawn groups, thereby reducing the workload of artificially clearing diseased prawns and dead prawns, improving the clearing efficiency and culture success rate, and bringing greater economic benefit for culturists.
Description
Technical field
The present invention relates to aquaculture field, be specifically related to a kind of biological preventing control method by grass carp control shrimp disease.
Background technology
Prawn is the pillar kind of China's culture fishery, and development in recent years is rapid, and to 130.3 ten thousand tons of cultured outputs in 2009, the output value is above 30,000,000,000 yuan; Foreign exchange earning occupies the Export of Chinese Aquatic Products amount of money the first, up to 12.3 hundred million dollars.Shrimp culture industry has become the target industry that China's agricultural structure is adjusted.
Yet the shrimp disease problem remains the main bottleneck of shrimp culture industry development.The habit that the outbreak of epidemic of prawn communicable disease and prawn kill and devour mutually itself has certain relation.In the prawn culturing process, indivedual physique are weak because the environmental condition deterioration causes, the prawn of premunition difference at first falls ill even death, the latter is preyed on by healthy individual, thereby causes infectious agent (bacterium/virus) to be propagated in prawn colony, finally causes the disease of prawn outbreak of epidemic.How in time, thoroughly remove sick shrimp in the shrimp culture pond and become one of key technology that the control disease of prawn breaks out.
The shrimp disease problem remains the main bottleneck of shrimp culture industry development.The major measure of current solution shrimp disease problem comprise improve the prawn resistance against diseases, improve the prawn culturing environment and cut off the route of transmission etc. of disease of prawn cause of disease several.But, since prawn white spot syndrome outbreak of epidemic in 1992, worldwide still do not found a kind of practical ways thoroughly to prevent the outbreak of epidemic of disease of prawn.The outbreak of epidemic of disease of prawn has caused serious economy loss for the shrimp culture industry of China, and according to estimates, annual economic loss is up to 3,000,000,000 yuan.
The sick shrimp of removing in the shrimp culture pond is a kind of method that prevents that disease of prawn from propagating.But, the method for the sick shrimp of present artificial removing exist find untimely, remove not thorough etc. limitation, be difficult to breaking out of control prawn communicable disease.In addition, the method that also has some prawn culturing patterns to adopt fishes and shrimps to raise together with is in the industry carried out the prevention and control of prawn disease.But, owing to, often can not receive desirable effect to not taking correct method in the selection of fish species, quantity, specification and release time.
Summary of the invention
The objective of the invention is to according to existing shrimps infectious disease transmission soon, problem such as the removing of sick shrimp is thoroughly not untimely provides a kind of cultural method that improves the prawn survival rate.
The object of the invention is achieved by the following technical programs:
A kind ofly carry out the method for prawn culturing, comprise the steps: by adding grass carp
(1) in the culture shrimp pond, throws in the shrimp seedling of 5 ~ 100,000 tail/mus;
(2) prawn culturing after 20 ~ 30 days every mu throw in 30 ~ 60 tail grass carps;
(3) the conventional cultivation.
As a kind of preferred version, in the said method, the body weight of described grass carp is more than the 1kg.
As a kind of preferred version, in the said method, the water in the described culture shrimp pond is degree of saltiness water, and salinity is 0 ~ 7.5.
As a kind of preferred version, in the said method, the shrimps of described shrimp seedling for being suitable in salinity 0 ~ 7.5, culturing.Further, described shrimps are that Environment of Litopenaeus vannamei Low, Penaeus monodon, Chinese prawn, Macrobrachium rosenbergii or base enclose shrimp.
The present invention has taken all factors into consideration the feeding habits of grass carp by a large amount of experiments, and factors such as the transmissibility of prawn disease and current prawn culturing technology, has determined said method.
Compared with prior art, the present invention has following beneficial effect:
(1) experiment showed, grass carp more than the heterophagous 1kg shrimp that dies of illness that only ingests by a large amount of in the shrimp culture pond, healthy shrimp does not ingest.This advantage of grass carp has solved other violent predacious fish because the healthy shrimp of hunting is caused the low problem of shrimps in culture survival rate;
(2) grass carp is cruised in the shrimp pond, can find and feed into the shrimp that dies of illness prior to healthy shrimp, can have to stop the healthy shrimp disease shrimp that ingests, thereby avoid prawn disease spread and epidemic in healthy shoal of shrimps;
(3) the grass carp shrimp that dies of illness of in time finding and ingest has reduced and has manually patrolled the workload that the shrimp that dies of illness is removed on the pool, has improved the efficient of removing the shrimp that dies of illness, has improved the breed success rate;
(4) utilize the outbreak of epidemic of grass carp prevention and control disease of prawn, reduced the use of various control shrimp disease medicines.Help the protection of ecotope on the one hand, help the raising of prawn quality on the other hand;
(5) grass carp itself also is a kind of economic fish, throws in grass carp provisions shrimp person in the shrimp pond and brings bigger economic benefit.
Embodiment
Further explain the present invention below in conjunction with embodiment, but embodiment does not do any type of qualification to the present invention.
Embodiment
1, according to the normal management method of prawn culturing, trained water after, throw in the shrimp seedling about 1.0cm, every mu 5～100,000 tails.Because grass carp is unsuitable for surviving in greater than 7.5 water body in salinity, so the salinity of breeding water body of the present invention is in 0～7.5 scope.If the salinity of breeding water body is greater than 7.5, the method for available interpolation fresh water reduces salinity, and salinity is controlled in the above-mentioned scope.
2, throw in grass carp in good time.About prawn culturing to 20～30 day, before breaking out, shrimp disease throws in grass carp.Often because shrimp seedling itself is just extensive dead early stage in breed, need not throw in grass carp before this in the breeding process.So when generally culturing 20～30, after the shrimp seedling is stable, throw in grass carp again; The grass carp quantity of throwing in can not be less than 30 tail/mus, and can suitably increase according to the density of putting the shrimp seedling in a suitable place to breed, but need not surpass 60 tail/mus; The specification of grass carp can not be less than the 1kg/ tail, because the grass carp appetite of small dimension is limited, if the shrimp that dies of illness, under the situation of existing prawn disease transmissibility, the small dimension grass carp can not in time be removed the disease shrimp, does not reach expected results.
The 6-7 month in 2010 began, 7 raisers have been selected on Ping Gang farm, Guangdong Province, 222 mu of the pond gross areas, the breeding density of Environment of Litopenaeus vannamei Low is 50,000 tail/mus, cultures 20-30 days, throws in the above grass carp 30-50 tail of body weight 1kg/mu when the body of prawn is about to 3-5cm, cultured 90-110 days, guttate morphea syndrome (WSS) outbreak of epidemic does not take place, and cultured prawn reaches 70-100 tail/kg specification of going on the market during October, cultures success rate 100%.Simultaneously, 363 mu of traditional fishes and shrimps of peripheral 14 raisers of investigation are raised together with pattern, and WSS outbreak of epidemic area 19.4%, 33% is cultured unsuccessful, form the onsite acceptance that this achievement of listing success rate 66.7%(has been organized by Guangdong Province Science and Technology Department).
