Mu buhinzi bw’isambaza zo muri Amerika y’Epfo, abahinzi benshi basanga isambaza zabo zirya buhoro buhoro kandi ntizikura inyama. Impamvu ni iyihe? Gukura guke kw’isambaza biterwa n’imbuto z’isambaza, ibiryo byazo, n’imicungire yazo mu gihe cy’ubworozi bw’amafi.Potasiyumu ihindukabishobora gukemura ikibazo cyo kugabanya indyo y’inyama no kubura ikura ry’inyama mu bworozi bw’isambaza. Bamwe mu borozi bavuze ko bariye ibiryo bisanzwe mu kwezi kwa mbere, ariko ntibarye cyane mu kwezi kwa kabiri, bituma aborozi benshi batekereza ko ari ikibazo cy’icyo cyambo kandi bakeka ko ubwiza bw’ibiryo by’isambaza ari bwo bwatumaga habaho kugabanuka k’ubushake bwo kurya isambaza no guhinduka k’ubwoko bw’ibiryo. Kubera iyo mpamvu, uburyo bwo kugabanya indyo y’isambaza ntibwarushijeho kuba bwiza, ndetse n’ibidendezi bimwe na bimwe byarushijeho gukomera.

Dukurikije ibi bibazo, impamvu zituma isambaza zo muri Amerika y'Epfo zigabanuka zishobora gusobanurwa muri make ku buryo bukurikira:

1. Impamvu y'imbuto z'isambaza:

Imbuto zimwe na zimwe z'ibishishwa zisanzwe zifite ingano zitandukanye, kandi imikurire yazo izatandukana mu gihe cyo guhinga nyuma. Hariho kandi imbuto z'ibishishwa ziva ahantu hatandukanye, akenshi zikura buhoro buhoro cyangwa zikareka gukura mu gihe cya nyuma.

2. Ubwiza bw'amazi:

Urugero rwinshi rwa azote ya amoniya, nitrite, na pH mu mazi rushobora gutera impinduka mu miterere y’isambaza zo muri Amerika y’Epfo, bityo bigira ingaruka ku mirire yazo.

3. Hari udukoko twinshi mu kidendezi:

ishobora gutanga ibinyabuzima byinshi byo kurya isambaza, kandi uburyo bwo kuzigaburira buzatinda muri iki gihe.

4. Ibintu bireba imicungire:

Ubucucike bwinshi bw'ibiryo, amazi make cyane, guhinduranya amazi adahagije, no kugaburira bidahagije (muri rusange bigenzurwa ku kigero cya 6-8% by'uburemere bw'umubiri) byose bishobora gutuma isambaza zitinda kugaburira.

 

Uretse ibintu byavuzwe haruguru bitera kororerwa isambaza buhoro, hari n'indwara za bagiteri na virusi. Isambaza zifite indwara zizarya buhoro.

Ingaruka za potasiyumu mu guhindura imiterere y'umusaruro w'isambaza zo muri Amerika y'Epfo:

Potasiyumu ihindukaIshobora kugabanya igipimo cy’indwara ya enteritis muri Penaeus vannamei. Potasiyumu diformate ntishobora gusa kunoza uburyo amara yinjira, guteza imbere igogora no kwinjiza poroteyine, guteza imbere ikura rya shrimp, ahubwo inateza imbere ukwiyongera no kwiyongera kwa bagiteri nziza mu mara, ikabuza bagiteri mbi mu mara, ikagenzura PH mu mara, igateza imbere iterambere ry’amara, ikabungabunga ubuzima bw’amara ya shrimp, ikagabanya cyane igipimo cy’indwara ya enteritis muri Penaeus vannamei, yongera cyane ubudahangarwa bw’ishrimp, yongera ubudahangarwa bw’indwara za shrimp, kandi ikanoza imbaraga za shrimp. Ingaruka zo kongeramo ingano zitandukanye za potassium diformate kugira ngo itange umusaruro wa shrimp y’umweru yo muri Amerika y’Epfo. Kongera 0.8% ya potassium diformate mu ndyo byongera uburemere bwose bwa shrimp y’umweru yo muri Amerika y’Epfo ku kigero cya 20.6%, ibiro byiyongera ku kigero cya 26% ku munsi, n’igipimo cyo kubaho ku kigero cya 7.8%. Ibisubizo by’igerageza bigaragaza ko kongera 0.8% bya potassium diformate mu biryo bya shrimp y’umweru yo muri Amerika y’Epfo bishobora kunoza cyane imikurire ya shrimp no kongera igipimo cyo kubaho kwazo.

Akamaro k'ingenzi ka potasiyumu diformate ni ukugira ingaruka zo kurwanya bagiteri na bagiteri, ibyo bikaba byakongera ubushobozi bwo kurwanya indwara z'isambaza no kongera ubuzima bwazo. Ibice by'ingenzi bigizepotasiyumu diformateishobora kugenga imiterere ya mikorobe zo mu mara no kubungabunga uburinganire bwa mikorobe zo mu mara, ibi bikaba bishobora kunoza uburyo amara y’isambaza yinjira, kongera imikorere ya poroteyine, kongera igogora n’ikoreshwa rya poroteyine y’ibiryo, kugabanya igipimo cy’ibiryo, kunoza uburyo isambaza zigaburira, no guteza imbere imikurire y’isambaza.
