Zvirwere Zvehove Zvakajairwa Mumadziva uye Kudzivirira Kwazvo: Zvirwere zveBhakitiriya uye Kutarisira Kwazvo

Zvirwere zvebhakitiriya zvakajairika muhove zvinosanganisira bacterial septicemia, bacterial gill disease, bacterial enteritis, red spot disease, bacterial fin rot, white nodules disease, and white patch disease.

1. Bacterial Septicemiainonyanya kukonzerwa neRenibacterium salmoninarum, Aeromonas, uye Vibrio spp. Kudzivirira uye nzira dzokurapa dzinosanganisira:

(1) Kunyatsochenesa dziva kuderedza kushandiswa kweokisijeni nedhaka rakawandisa.

(2) Kugara uchitsiva nekuwedzera mvura yakachena, kuisa lime kuvandudza kunaka kwemvura uye nzvimbo yemadziva, uye kupa zvakakosha calcium zvinhu.

(3) Kusarudza mhando dzehove dzemhando yepamusoro uye chikafu chine hutano.

(4) Kugara kuuraya utachiona hwehove, chikafu, maturusi, uye zvivakwa, kunyanya kushandisa mishonga yekudzivirira mukati memwaka wechirwere chepamusoro, uye kuongororwa nekukurumidza uye kurapwa.

(5) Kushandisa bromine-based disinfectants yekuuraya utachiona hwemvura kana kugadzirira gadziriro dzine iodine kuhove.

2. Bhakitiriya Gill Chirwereinokonzerwa necolumnaris bacteria. Matanho ekudzivirira anosanganisira kunyudza hove dzakakangwa mumvura ine munyu panguva yekupatsanurwa kwedhamu kuitira kuderedza kutapurirana kwebhakitiriya. Kana pakaitika denda, zvinokurudzirwa kushandisa lime kana chlorine agents seTCCA kana chlorine dioxide pakubvisa utachiona mudhamu rose.

3. Bhakitiriya Enteritisinokonzerwa ne enteric Aeromonas. Zvinowanzoitika nekuderera kwemhando yemvura, sediment kuunganidzwa, uye yakakwira organic zvinhu zvirimo. Kudzora kunosanganisira kuuraya hutachiona hwedhamu nechlorine-based agents, zvakasanganiswa nekudyisa chikafu chinowedzerwa neflorfenicol.

4. Red Spot Diseaseinokonzerwa neFlavobacterium columnare uye inowanzoitika mushure mekuchengetedza kana kukohwa, zvinowanzoitika pamwe chete nechirwere chegill. Matanho ekudzora anosanganisira kunyatsochenesa dziva, kudzivirira kukuvara kwehove panguva yekubata, uye kushandisa mabhati ekugezera panguva yekuisa. Kugara dhamu rese disinfection zvichienderana nemhando yemvura inorairwa zvakare.

5. Bhakitiriya Fin Rotinokonzerwa necolumnaris bacteria uye inowanikwa muchirimo, chirimo, uye matsutso. Kudzora kunosanganisira kudzivirira disinfection yemvura uchishandisa chlorine-based agents.

6. White Nodules Diseaseinokonzerwa ne myxobacteria. Kudzorwa kwechirwere kunoda kusimudzirwa kwekutonga kwekudya kuti ive nechokwadi chekudya chakaringana uye nharaunda yakanaka, pamwe neapo neapo mudhamu rekuuraya hutachiona uchishandisa chlorine-based agents kana lime.

7. White Patch Diseaseinokonzerwa neFlexibacter uye Cytophaga spp. Kudzivirira kunosanganisira kuchengetedza mvura yakachena uye kupa chikafu chakakwana chakakwana, pamwe chete ne periodic yese yekuuraya utachiona padziva uchishandisa trichloroisocyanuric acid, bleach, kana Terminalia chebula zvinyorwa.

Aya matanho anobatsira zvinobudirira kubata zvirwere zvebhakitiriya mumadziva emvura, kuve nechokwadi chehuwandu hwehove dzine hutano uye nharaunda dzemadziva dzakavandudzwa.
