Phuputso ea morao tjena e entsoeng ke Aquaculture Research Institute e bontšitse liphello tse tšepisang bakeng sa tšebeliso eaasiti trichloroisocyanuric(TCCA) temong ea li-shrimp.TCCA ke sebolaya ditwatsi le khemikhale e hlwekisang metsi ka bongata, empa bokgoni ba yona ba ho sebediswa temong ya metsing bo ne bo eso hlahlojwe ka botlalo ho fihlela jwale.
Boithuto bona, bo neng bo tšehelitsoe ka lichelete ke National Science Foundation, bo ne bo reretsoe ho batlisisa litlamorao tsa TCCA kholong le bophelo bo botle ba li-shrimp tse tšoeu tsa Pacific (Litopenaeus vannamei) tsamaisong e potolohang ea metsi.Bafuputsi ba ile ba lekola likarolo tse fapaneng tsa TCCA ka metsing, ho tloha ho 0 ho isa ho 5 ppm, mme ba beha leihlo shrimp nako ea libeke tse ts'eletseng.
Liphello li bontšitse hore li-shrimp tse ka har'a litanka tse tšoaroang ke TCCA li ne li e-na le litekanyetso tse phahameng haholo tsa ho pholoha le litekanyetso tsa kholo ho feta tsa sehlopha sa taolo.Tekanyo e phahameng ka ho fetisisa ea TCCA (5 ppm) e hlahisitse liphello tse molemo ka ho fetisisa, ka tekanyo ea ho pholoha ea 93% le boima ba ho qetela ba ligrama tsa 7,8, ha li bapisoa le tekanyo ea ho pholoha ea 73% le boima ba ho qetela ba ligrama tsa 5,6 sehlopheng sa taolo.
Ntle le litlamorao tse ntle tsa kholo ea li-shrimp le ho phela, TCCA e boetse e ipakile e sebetsa ho laola kholo ea libaktheria tse kotsi le likokoana-hloko metsing.Sena se bohlokoa temong ea li-shrimp, kaha likokoana-hloko tsena li ka baka mafu a ka senyang bongata bohle ba li-shrimp.
Tšebeliso eaTCCAka aquaculture ha ho na khang, leha ho le joalo.Lihlopha tse ling tsa tikoloho li bontšitse ho tšoenyeha ka monyetla oa hore TCCA e hlahise lihlahisoa tse kotsi ha e sebetsana le lintho tse phelang metsing.Bafuputsi ba ts'ebetsong ea phuputso ba amohela lipelaelo tsena, empa ba supa hore liphetho tsa bona li fana ka maikutlo a hore TCCA e ka sebelisoa ka mokhoa o sireletsehileng le ka katleho temong ea metsing libakeng tse nepahetseng.
Mohato o latelang bakeng sa bafuputsi ke ho etsa lithuto tse ling ho batlisisa liphello tsa nako e telele tsa TCCA mabapi le kholo ea shrimp, bophelo bo botle le tikoloho.Ba tšepa hore seo ba se fumaneng se tla thusa ho theha TCCA e le sesebelisoa sa bohlokoa bakeng sa lihoai tsa shrimp lefatšeng ka bophara, haholo-holo libakeng tseo mafu le lintho tse ling tsa tikoloho li bakang tšokelo e kholo ho batho ba li-shrimp.
Ka kakaretso, thuto ena e emetse mohato oa bohlokoa oa ho ea pele ts'ebelisong ea TCCA temong ea metsing.Ka ho bontša bokhoni ba eona ba ho ntlafatsa kholo ea shrimp le ho phela, ha e ntse e laola likokoana-hloko tse kotsi, bafuputsi ba bontšitse hore TCCA e na le karolo ea bohlokoa eo e lokelang ho e bapala nakong e tlang ea temo e tsitsitseng ea shrimp.
