The pathogene of sessilinasis is modal is Zoothamnium, single contracting worm, microsporidian, worms on a sucker, tired branch worm and vorticella etc.They all belong to ciliates, take the fragment of bacterium and other microorganisms or epidermal cells of host as food, directly do not encroach on host's tissue, and just with the base of host as its epiphytism.When these colonies grow nonparasitically upon another plant in a large number on the crust of shrimp crab, with the naked eye can see one deck suede hair.If these colonies and mold fungi or filamentous algae occur roughly the same the time, its pathogenic will being enhanced is particularly adhered on the gill filament of shrimp crab, can affect the gill filament to the exchange of oxygen, and the shrimp crab is descended to the endurance of anoxic.When colony adhere to quantity when few, its harm is little because the shrimp crab is once shell, these colonies will disappear thereupon.When adhering in a large number, will hinder the shrimp crab eupnea, swim, ingest, simultaneously also the difficult disease that shells can appear, stop growing.Indivedual successful shellers, due to infusorian parasitic site chitin calcification, new and old shell adhesion is and injured, and often the secondary bacterium infects and death.In addition, commercial sized prawn crab body surface is attached with infusorian, and body surface will produce obvious white cotton floccule, and being placed in water also can be movable, has a strong impact on the commodity of shrimp and crab.Owing to striving in the market ciliophoran medicine, main take single zinc sulphate as main, and zinc sulphate causes infusorian to produce serious pesticide resistance to it due to the long-term use through the more than ten years, the raiser does not reuse by dosage and has effect.
The strong chlorine oil Main Ingredients and Appearance is sym-closene, is a kind of extremely strong oxidant and chlorinating agent, has efficient, wide spectrum, safer disinfective action, and bacterium, virus, fungi, gemma etc. are had killing action, and coccidian oocyst is also had certain killing effect.These product are widely used in food processing, drinking water disinfection.Be mainly used in swimming sterilizing abroad; The domestic aspects such as culture fishery, sericulture and waste water treatment that are mainly used in.
Summary of the invention
The purpose of this invention is to provide a kind of control freshwater shrimp and the ciliophoran method of river crab, adopt zinc sulphate and high concentration strong chlorine oil (sym-closene), fundamentally solve all kinds of problems that caused by infusorian in shrimp crab breeding process under the acting in conjunction of two kinds of medicines, thereby improve the survival rate of shrimp crab cultivation and the quality of commercial sized prawn crab.
To achieve these goals, the technological means of the present invention's employing is:
A kind of method of preventing and treating freshwater shrimp fibre and river crab caterpillar comprises the steps:
1) check shrimp or crab body: fish for part freshwater shrimp or river crab, check whether surface or the gill filament have infusorian;
2) change water: if infusorian is arranged, change the water body in pond 1/3 ~ 1/4;
3) mixed medicine: with zinc sulphate and strong chlorine oil (sym-closene), mixing is soluble in water, and the amount of water is according to the pond size, is advisable Yi Bian splash with enough whole ponds just in time;
4) splash: step 3) in the liquid full pool spilling head that mixes in the pond;
5) check shrimp or crab body: splash medicine after 5～7 days, fishing freshwater shrimps or river crab, as remaining in also having infusorian again, repeating step 3) and 4).Thoroughly kill and paying on freshwater shrimp or river crab and the infusorian in water.
Described step 3) in, the consumption of zinc sulphate is that each Mi Shuishen of every mu of pond uses 600～750g, and the consumption of strong chlorine oil is that each Mi Shuishen of every mu of pond uses 300～400 g.
Beneficial effect: the present invention has certain strong oxidizing property of killing ciliophoran effect and high concentration strong chlorine oil (sym-closene) according to zinc sulphate, has the effect of sterilization and purifying water body, in conjunction with the acting in conjunction of two kinds of medicines; Solve the balantidiasis problem in freshwater shrimp and culture of Chinese mitten crab process, realize healthy ecology cultivation freshwater shrimp or river crab, improve survival rate and the commodity of cultivation.
