Abstract
The invention discloses an ecological Australia murray cod ichthyophthiriusmultifiliis preventing technology. When the ichthyophthiriusmultifiliis occurs on Australia murray cod, sea water is added into a water body where the Australia murray cod is located, detecting is conducted timely through a salinity meter, the salinity is controlled to be 8 thousandths to 10 thousandths, soaking is conducted for 48h, and the ichthyophthiriusmultifiliis is killed. After conducting some deep and basic research on the ultrastructure, the infection mechanism, pathogenesis and immunoreaction and the like of the ichthyophthiriusmultifiliis, the fact that a life cycle of the ichthyophthiriusmultifiliis is divided into stages of trophozoite, cyst and predation is found out. An ichthyophthiriusmultifiliis body is weak during the predation stage and can be restrained effectively by changing the environment, bad effects of pesticide on fish can be avoided, and meanwhile the ichthyophthiriusmultifiliis can be killed thoroughly and effectively.
Description
Technical field
The present invention relates to a kind of cultivation Prevention Technique, be specifically related to the technology of the little melonworm of a kind of bionomic control Australia dragon design spot.
Background technology
Dragon design spot formal name used at school worm line river blackfish, have another name called unauspicious cod, river cod, worm hamlet, Australia fresh water river blackfish.Original producton location is one of warm water fish of the fresh water of unauspicious Darling R. basin, Australian southeast ，Wei Australia four large artificial propagations, because of its unique profile, delicious mouthfeel, adds quantity rare, therefore the laudatory title of " Australia national treasure fish " is arranged; The dragon design spot is again the high fish of a kind of nutritive value simultaneously.In the flesh of fish, amino acid content can reach 20%, be rich in necessary amino acid, and fat content is only 2%, the dietetic requirement of very applicable modern's health.
Ich is again " ichthyophthirius ", is the freshwater fish that caused by ichthyophthirius multifiliis and a kind of common parasitosis of fancy fishes.This disease is widely distributed, and harm is serious, is the large illness of one in aquaculture, if treatment not in time after morbidity, the lethality of fingerling can reach 60 %～70 %, reaches 80 %～90 % when serious, causes serious economic loss.At present, this disease of medical treatment faces day by day serious two puzzlements greatly: 1. can effectively kill the medicine of little melonworm such as malachite green, mercurous nitrate, mercurous acetate etc. and be prohibited for the aquatic products disease prevention and cure owing to having significantly carcinogenic, teratogenesis characteristic, and other medicines such as copper sulphate, formalin, methylene blue etc. are invalid to polypide in vesica.In the U.S., 3 kinds of chemicalss food fish and the fish-egg parasitosis be used to preventing and treating cultivation, i.e. formalin, salt and acetic acid are legally arranged.But except little water body, it is unpractical using these 3 kinds of chemicalss, because they are difficult to use at large water body, and expensive, the development speed of new drug is unable to catch up with the speed that polypide produces drug resistance far away simultaneously; 2. the expense of developing new drug is extremely expensive.In the U.S., only register one just up to 7,000 ten thousand dollars, 9a that the time of examining of united states drug and food control office (FDA) is also spun out 1978 from the 3a in generation nineteen sixty.Some major companies also hope and halt the development of new drug.Residual and the problem of environmental pollution of medicine is outstanding in addition, and some developed countries are more and more tighter to the medicament residue examination criteria of aquatic products, stopped the use of some original common drugs.These reasons force people to turn on to seek to be cut off little melonworm with ecology regulation and control and prevents and treats ich the history of life.Research is found, by immunization route, prevent and treat ich and have certain effect, but this is also just rested on laboratory stage.
Summary of the invention
Goal of the invention: the present invention, in order to solve the deficiencies in the prior art, provides the technology of the little melonworm of a kind of bionomic control Australia dragon design spot.
Technical scheme: the technology of the little melonworm of a kind of bionomic control Australia dragon design spot, when finding that Australia dragon design spot little melonworm occurs with it, at this moment in the water body at dragon design spot place, described Australia, add seawater, with salinometer, detect in time, salinity is controlled to 8 ‰-10 ‰, soak 48h, thereby kill little melonworm.
Beneficial effect: the technology of the little melonworm of a kind of bionomic control of the present invention Australia dragon design spot, after by the ultra microstructure to little melonworm, infection mechanism, pathogenesis and immune response etc., doing some in depth basic research, find, little melonworm is divided into trophozoite, packing, grazing eclipse stage the history of life, wherein polypide is comparatively fragile the theront stage, now change environment polypide is had to good inhibitory action, the harmful effect of deinsectization medicine to fish can be avoided, little melonworm can be thoroughly effectively killed simultaneously.
Embodiment
The invention will be further described below in conjunction with specific embodiment:
Embodiment 1:
The technology of the little melonworm of a kind of bionomic control Australia dragon design spot, when finding that Australia dragon design spot little melonworm occurs with it, at this moment add seawater in the water body at dragon design spot place, described Australia, with salinometer, detect in time, salinity is controlled to 8 ‰, soak 48h, thereby kill little melonworm.
Embodiment 2:
The technology of the little melonworm of a kind of bionomic control Australia dragon design spot, when finding that Australia dragon design spot little melonworm occurs with it, at this moment add seawater in the water body at dragon design spot place, described Australia, with salinometer, detect in time, salinity is controlled to 9 ‰, soak 48h, thereby kill little melonworm.
Embodiment 3:
The technology of the little melonworm of a kind of bionomic control Australia dragon design spot, when finding that Australia dragon design spot little melonworm occurs with it, at this moment add seawater in the water body at dragon design spot place, described Australia, with salinometer, detect in time, salinity is controlled to 10 ‰, soak 48h, thereby kill little melonworm.
The above is only the preferred embodiment of the present invention, is noted that the common skill for the art
Art personnel, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
Claims (1)
1. the technology of the little melonworm of bionomic control Australia dragon design spot, it is characterized in that: when finding that Australia dragon design spot little melonworm occurs with it, at this moment in the water body at dragon design spot place, described Australia, add seawater, with salinometer, detect in time, salinity is controlled to 8 ‰-10 ‰, soak 48h, thereby kill little melonworm.
