MPT [Ibiranga]:

Iki gicuruzwa kibereye kuroba umwaka wose, kandi kibereye cyane ahantu hafite umuvuduko muke n'ahantu ho kuroba mu mazi akonje.

Iyo nta mwuka urimo mu mazi, ni byiza guhitamo icyambo cya DMPT. Kibereye ubwoko bwinshi bw'amafi (ariko ubushobozi bwa buri bwoko bw'amafi bushobora gutandukana), hamwe n'umubare munini w'amafi aterana kandi amara igihe kirekire, kandi akora neza cyane mu bice bifite umwuka muke. Bishobora kongera ibyishimo n'ibyishimo ku bakunda kuroba.

Ikintu cy'ingenzi:

Dimethyl-β- Propiothetin, ubuziranenge burenga 98% cyangwa 85%.

[ikoreshwa n'igipimo]:

1. Bikwiriye amafi yo mu bwoko bwa omnivorous (crucian carp, carp, bream), ayo mu bwoko bwa grass carp, ayo mu bwoko bwa filter (silver carp, bighead carp), n'ayo mu bwoko bwa catfish (catfish, yellow catfish, nyuma yo kumva uburyohe bw'ibyari byazo, agomba kumanika ibiryo by'amatungo ku rushundura), ndetse n'amafi yo mu bwoko bwa crustacean nka shrimp na turtles mu mazi meza. Ibiryo byo mu mazi yo mu nyanja bigomba kubanza kunyobwa n'uyu muti.

2. Kuroba nijoro, kuroba muri Tayiwani ni byo byiza kurusha ibindi, kandi bishobora no gukoreshwa nk'inkoni yo kuroba ku biribwa bike.

3. Ibidendezi, ibiyaga, imigezi, ibigega, inyanja ntoya. Koresha amazi afite ubwinshi bwa ogisijeni burenga miligarama 4 kuri litiro nta mpungenge ya ogisijeni ihagije.

4. Ni byiza kongeramo garama 0.5-1.5 za DMPT mu gihe cyo gutera amafi mu cyaro kugira ngo amafi yihute ajye mu cyaro. Mu gutegura icyambo, igipimo cy'ibiryo byumye ni 1-5%, bivuze ko garama 5 za DMPT na garama 95 kugeza kuri garama 450 z'ibiryo byumye bishobora kuvangwa neza.

5. DMPT ishobora gushonga mu mazi yaciwe cyangwa asukuwe, hanyuma igashyirwa mu mazi afite ubunini bwinshi kugira ngo ivange n'umutego. Gukoresha umutego n'umutego ni bimwe, ku buryo DMPT ingana mu mutego iba iri hejuru. Byongeye kandi, DMPT ishobora kuvangwa mbere n'ibikoresho fatizo by'ifu mu bikoresho fatizo by'umutego ishyirwa mu mifuka ya pulasitiki ifunze neza cyangwa mu mifuka y'icyitegererezo hanyuma ikazunguruka kugira ngo ivange neza kandi ihuze. Hanyuma, hashobora kongerwamo 0.2% by'umuti w'amazi wa DMPT kugira ngo uhindurwe.

Byongeye kandi, kugira ngo hirindwe kuvanga n'ibindi bigega by'ubucuruzi no guhindura imiterere yabyo n'impumuro yabyo, ni byiza ko inshuti z'abarobyi zigerageza gukoresha ibigega by'ingano gusa. Birumvikana ko niba ibigega by'ingano gusa bitaboneka, ibigega by'ubucuruzi nabyo bishobora gukoreshwa.

Ushobora guteka ibiryo by’ibinyampeke cyangwa ibiryo by’ibinyampeke byo mu rugo. Urugero, igipimo cya DMPT kiri hejuru ni iki gikurikira: garama 5 za DMPT, zishongeshejwe mbere ya mililitiro 100 z’amazi meza, zivanze neza kandi zigashonga neza mbere yo kuvanga na garama 95 z’ibiryo byumye, hanyuma igipimo cya 0.2% cy’umuti uvangwa wongerwaho hakurikijwe urwego rw’umuma n’ubutose. (5%) Urugero rw’igipimo cya DMPT kiri hasi: garama 5 za DMPT, zishongeshejwe mbere ya mililitiro 500 z’amazi meza, zivanze neza kandi zigashonga neza, zikoreshwa mu kuvanga na garama 450 z’umuti wumye, kandi zongeweho igipimo cya 0.2% cy’umuti uvangwa neza hakurikijwe urwego rw’umuma n’ubutose. (1%) Gutegura umuti uvangwa na DMPT: garama 2 za DMPT, zishongeshejwe mbere ya mililitiro 1000 z’amazi (0.2%), ziteguwe nk’umuti uvangwa neza kugira ngo zizakoreshwe mu gihe kizaza. Gutegura DMPT n'umuyoboro wumye (1%): Fata garama 5 za DMPT na garama 450 z'ibindi bikoresho fatizo ubishyire mu ishashi ya pulasitiki ifunze neza, uzunguze irya n'ino, hanyuma uvange neza. Umaze kubikuramo, ongeramo ingano ikwiye ya 0.2% ya DMPT dilute kugira ngo utegure umuyoboro ukenewe. Gutegura DMPT n'umuyoboro wumye (2%): Fata garama 5 za DMPT na garama 245 z'ibindi bikoresho fatizo ubishyire mu ishashi ya pulasitiki ifunze neza, uzunguze irya n'ino, hanyuma uvange neza. Umaze kubikuramo, ongeramo ingano ikwiye ya 0.2% ya DMPT dilute kugira ngo utegure umuyoboro ukenewe. Gutegura DMPT n'umuyoboro wumye (5%): Fata garama 5 za DMPT na garama 95 z'ibindi bikoresho fatizo ubishyire mu ishashi ya pulasitiki ifunze neza, uzunguze irya n'ino, hanyuma uvange neza. Umaze kubikuramo, ongeramo ingano ikwiye ya 0.2% ya DMPT dilute kugira ngo utegure umuyoboro ukenewe.

6. Ni byiza gutegura icyambo cyawe bwite, kuko DMPT ikwirakwira neza mu cyambo, ifite umuvuduko umwe wo kurekura mu mazi kandi igakomeza igihe kirekire. Iyo ari icyambo cyakozwe, gishobora no kwinjizwa mu ijoro ryose mu gikoresho cya DMPT cyuzuyemo ingano.
