Hom ntses kab mob hauv cov pas dej thiab lawv txoj kev tiv thaiv: Kab mob kis kab mob thiab tiv thaiv lawv

Cov kab mob ntses feem ntau tuaj yeem muab faib ua kab mob, kab mob kab mob, kab mob fungal, thiab kab mob parasitic. Kev kuaj mob thiab kho cov kab mob ntses yuav tsum nruj me ntsis ua raws li cov lus qhia kho mob, ua tib zoo saib xyuas cov tshuaj noj tshuaj yam tsis muaj kev txiav txim siab nce lossis txo qis.

Cov kab mob sib kis muaj xws li kab mob hemorrhagic ntawm nyom carp, hematopoietic kab mob necrosis ntawm crucian carp, herpesviral dermatitis ntawm carp, caij nplooj ntoos hlav viremia ntawm carp, kis kab mob pancreatic necrosis, kis kab mob hematopoietic nqaij necrosis, thiab viral hemorrhagic septicemia.

Kab mob Hemorrhagic ntawm Nyom Carp feem ntau tshwm sim los ntawm nyom carp reovirus. Tus kab mob no zuj zus nrog cov dej tsis zoo thiab yog qhov hnyav tshaj plaws nyob rau hauv lub caij nyoog tsis tshua muaj oxygen. Kev tiv thaiv thiab kev kho mob muaj xws li kev tua kab mob hauv pas dej, da dej ua ntej tso tshuaj, tshuaj tiv thaiv kab mob, tshuaj kho mob, tshuaj tua kab mob, thiab tshem tawm cov kab mob kis hauv dej.

Kev txhim kho thiab tshuaj tua kab mob hauv qab dej hauv qab feem ntau yog tshem tawm cov av ntau dhau, txhim kho lub pas dej hauv av, thiab siv cov kua qaub thiab tshuaj dawb rau tshuaj tua kab mob.

Cov tshuaj da dej ua ntej tuaj yeem siv 2% ~ 3% ntsev rau 5 ~ 10 feeb lossis 10 ppm polyvinylpyrrolidone-iodine tov rau 6 ~ 8 feeb, lossis 60 mg / L polyvinylpyrrolidone-iodine (PVP-I) da dej li 25 feeb.

Kev txhaj tshuaj tiv thaiv yog tsom rau kev sib cais ntawm cov noob kom nruj kom tsis txhob kis tus kabmob.

Kev kho tshuaj tuaj yeem suav nrog tooj liab sulfate. Copper sulfate tuaj yeem siv tau ntawm qhov concentration ntawm 0.7 mg / L hla tag nrho lub pas dej, rov ua dua txhua hnub rau ob daim ntawv thov.

Cov kev siv tshuaj tua kab mob muaj xws li kev siv cov pas dej ua kom sai rau kev tua kab mob thiab kev txhim kho dej zoo, los yog potassium hydrogen sulfate complex yaj thiab thov rau dej tua kab mob.

Txhawm rau tshem tawm cov kab mob kab mob hauv dej, kev npaj iodine tuaj yeem txau. Rau cov pas dej uas muaj kab mob hemorrhagic hauv cov nyom carp, polyvinylpyrrolidone-iodine lossis quaternary ammonium iodine complexes (0.3-0.5 ml ib cubic dej) tuaj yeem txau 2-3 zaug txhua hnub.

Hematopoietic Organ Necrosis Disease ntawm Crucian Carp yog tshwm sim los ntawm koi herpesvirus II. Kev tiv thaiv thiab kev kho mob muaj xws li:

(1). Tsis tu ncua cais niam txiv ntses ntawm cov ntses ua liaj ua teb kom tiv thaiv kev yug me nyuam ntawm niam txiv kab mob. Thaum muas crucian carp seedlings, xyuas kom meej tias lawv tau soj ntsuam los yog nug txog cov kab mob keeb kwm ntawm cov yub qhov chaw kom tsis txhob yuav cov noob kab mob.

(2). Kev siv cov kab mob photosynthetic, Bacillus spp., thiab denitrifying cov kab mob ua cov kab mob microbial, nrog rau kev hloov pauv hauv substrate, kom muaj txiaj ntsig zoo nyob rau hauv thaj chaw dej aquaculture. Tsis tas li ntawd, kev tswj xyuas cov dej kom txaus, ua kom cov dej ntshiab ntshiab, thiab ua kom cov dej ntws mus rau tus kheej thiab sab nraud yog qhov muaj txiaj ntsig zoo rau kev tuav dej ib puag ncig kev ruaj ntseg.

Herpesviral Dermatitis ntawm Carp yog lwm yam kab mob los ntawm herpesvirus. Kev tiv thaiv thiab kev tswj xyuas muaj xws li:

(1) Txhim kho kev tiv thaiv kev tiv thaiv thiab kev tswj hwm nruj. Cais cov ntses muaj kab mob thiab tsis txhob siv lawv ua cov ntses niam txiv.

(2) Kev siv tshuaj tua kab mob hauv lub pas dej kom zoo siv ceev ceev hauv cov pas dej ntses, thiab tua kab mob hauv dej nrog cov ntses kab mob los yog cov kab mob yuav tsum tau kho kom zoo, zoo dua tsis txhob siv los ua dej.

(3) Kev txhim kho dej zoo tuaj yeem koom nrog kev kho dej hauv pas dej pH nrog ceev ceev kom tswj tau nws saum toj no 8. Daim ntawv thov puv pas dej ntawm dibromide lossis bromide tuaj yeem siv rau kev tua kab mob hauv dej. Xwb, daim ntawv thov puv pas dej ntawm povidone-iodine, compound iodine tov, 10% povidone-iodine tov, los yog 10% povidone-iodine hmoov tuaj yeem ua tiav cov dej tua kab mob.

Caij nplooj ntoos hlav Viremia ntawm Carp yog tshwm sim los ntawm lub caij nplooj ntoos hlav viremia virus (SVCV), uas tam sim no tsis muaj kev kho mob zoo. Txoj kev tiv thaiv muaj xws li kev siv cov kua qaub los yog tshuaj dawb rau lub pas dej kom puv, tshuaj tua kab mob chlorinated, lossis cov tshuaj tua kab mob zoo xws li povidone-iodine thiab quaternary ammonium ntsev rau cov tshuaj tua kab mob los tiv thaiv kev sib kis.

Kab mob pancreatic necrosis yog tshwm sim los ntawm tus kab mob pancreatic necrosis, feem ntau cuam tshuam rau cov ntses dej txias. Kev kho mob thaum ntxov muaj kev noj zaub mov nrog povidone-iodine tov (xws li 10% zoo iodine) ntawm 1.64-1.91 g ib kg ntses lub cev hnyav txhua hnub rau 10-15 hnub.

Kab mob Hematopoietic Tissue Necrosis yog tshwm sim los ntawm cov kab mob hematopoietic necrosis, feem ntau cuam tshuam rau cov ntses dej txias. Kev tiv thaiv yuav tsum nruj me ntsis tshuaj tua kab mob ntawm aquaculture chaw thiab cov cuab yeej. Cov qe ntses yuav tsum tau hnia ntawm 17-20 ° C thiab ntxuav nrog 50 mg / L polyvinylpyrrolidone-iodine (PVP-I, muaj 1% zoo iodine) rau 15 feeb. Concentration tuaj yeem nce mus rau 60 mg / L thaum pH yog alkaline, vim tias qhov ua tau zoo ntawm PVP-I txo qis hauv cov kab mob alkaline.

Viral Hemorrhagic Septicemia yog tshwm sim los ntawm Novirhabdovirus hauv tsev neeg Rhabdoviridae, ib tus kab mob RNA ib leeg. Tam sim no, tsis muaj kev kho mob zoo, yog li kev tiv thaiv tseem ceeb heev. Thaum lub sij hawm lub qhov muag qe, soak qe nyob rau hauv iodine rau 15 feeb. Thaum ntxov ntawm tus kab mob, kev noj zaub mov nrog iodine tuaj yeem txo qis kev tuag.
