Kudzidza kutsva kunoratidza kugona kweTrichloroisoisoCocyanuric Acichic acid mune shrimp yekurima

Ongororo ichangobva kuitika inoitwa neiyo aquaculture research Institute yakaratidza kuvimbisa mhedzisiro yekushandiswa kwetrichloroisocyanuric acid(Tcca) mu shrimp yekurima. TCCA izere inoshandiswa zvakanyanya uye kurapwa kwemvura kwemakemikari, asi kugona kwayo kwekushandiswa mukukatyamadzwa hakuna kunyatsoongororwa kusvika zvino.

Chidzidzo ichi, icho chakapihwa mari yeNyika Science, chinangwa chekuongorora mhedzisiro yeTCCA pakukura uye hutano hwePacific chena Vaongorori vakaedza kusiyana kwakasiyana kweTCCA mumvura, kubva pa0 kusvika ku5 ppm, uye kutariswa shrimp kwenguva yemavhiki matanhatu.

Mhedzisiro yacho yakaratidza kuti shrimp mumatangi eTCCA-akarapwa yaive yakakwira zvakanyanya kupona mitengo uye kukura kwemitero kupfuura avo vari muboka rekutonga. Iyo yepamusoro yepamusoro yeTCCA (5 PPM) yakanakira mhedzisiro, neyekupona kwe93% uye uremu hwekupedzisira hwe77, uchifananidzwa nehuwandu hwe73 uye uremu hwekupedzisira hwe5,6 muboka revashanu.

Pamusoro pemhedzisiro yayo yakanaka pakukura kwayo uye kupona, Tcca zvakare inoshanda mukudzora kukura kwehutachiona hunokuvadza uye zvipembenene mumvura. Izvi zvakakosha pakurima kweshiri, sezvo aya matanda anogona kukonzeresa zvirwere zvinogona kuparadza vanhu vese vetsvina.

Kushandiswa kweTccaMukukara haina kana pasina gakava, zvisinei. Mimwe mapoka epakatiripiti akaratidzira kunetseka nezve mukana weTCCA kuti igadzire zvinokuvadza zvinokuvadza pazvinhu zve organic mumvura. Vatsvagiri kumashure kwekudzidza vanobvuma izvi, asi vanoratidza kuti mhedzisiro yavo inoratidza kuti TCCA inogona kushandiswa zvakachengeteka uye zvinobudirira mukukara kwekukatyamadza.

Nhanho inotevera kune vaongorori ndeyokuitisa zvimwe zvidzidzo kuti vaongorore miganho yeTCCA pane shrimp kukura, hutano uye nharaunda. Vanovimba kuti zvavakawana zvichabatsira kutanga TCCA sechishandiso chevarimi vegwende kutenderera nyika, kunyanya mumatunhu kune hosha uye zvimwe zvinhu zvezvakatipoteredza zvinyadzo kutyisidzira kwehuwandu hweshiri.

Zvakawanda, ichi chidzidzo chinomiririra nhanho yakakosha yekumberi mukushandiswa kweTCCA mune aquaculture. Nekuratidza kugona kwavo kugadzirisa kukura kweshiri uye kupukunyuka, apo zvakare vanodzora hutachiona hunokuvadza, vaongorori vakaratidza kuti TCCA inokosha kutamba mune ramangwana rekurima shrimp retimp.
