UHung wavula ngokushesha umoya ophuthumayo futhi waqala ukushintshana ngamanzi okuyingxenye. Ngemva kwamahora angamashumi amane nesishiyagalombili, amapulazi amathathu ezinhlanzi aseduze angenalo uhlelo abhekana nezigameko zokufa kwabantu abaningi okwabangela ukulahlekelwa okungaphezu kwesigidi samaRandi, kuyilapho ukulahlekelwa kwakhe kwancishiswa kwaba ngaphansi kuka-5%.
“Inzwa yendabuko yabonisa umoya-mpilo oncibilikile ojwayelekile ngaleso sikhathi,” kukhumbula uHung.
Iphepha elimhlophe lango-2023 elikhishwe yi-Asian Aquaculture Society lembule iqiniso elimangazayo: cishe ama-85% ezifo ezinkulu zasemanzini aqala ngenxa yokungalingani kwemingcele yamanzi, okuvame ukuphuthelwa ngenxa yezindlela zokuqapha.
“Inkinga ukunganeli kokuqapha,” kusho uSolwazi Li Minghao, uMqondisi weSikhungo se-Aquatic Biotechnology eNational University of Singapore. “Ukwehla komoya-mpilo oncibilikisiwe kuvame ukuba umphumela, hhayi umsuka, wokwehla kwekhwalithi yamanzi. Izimpawu zesixwayiso zangempela zivame ukufihlwa ezinguqukweni ezihlobene zamapharamitha afana ne-COD ne-pH.”
Izindawo Ezine Ezinkulu Zokuqapha Ezingaboni Amapulazi Abhubhisa Buthule
1. Indawo Engaboni Ye-COD: 'Umbulali Othule' Wokungcola Kwezinto Eziphilayo
Esimweni saseVietnam, ukwanda kwe-COD okungakatholakali kwabonisa ukunqwabelana kwemfucuza yokudla kanye nokukhishwa kwayo. Njengoba lezi zinto eziphilayo zibola, zidla umoya-mpilo futhi zikhiqize ubuthi obufana ne-ammonia ne-nitrite. Abalimi bendabuko bavame ukuqaphela inkinga kuphela lapho izinhlanzi zibonisa izimpawu zobuthi.
2. Ukuzinza Okukhohlisayo kwe-pH
Ucwaningo oluvela ku-UC Davis lubonisa ukuthi izinguquko ezincane ze-pH (±0.3) zingandisa ubuthi be-ammonia ngokuphindwe ka-3-5. Izinzwa eziningi ze-pH zasepulazini azinawo ukunemba noma ukulinganiswa ngesikhathi, okushiya izinhlanzi zisengozini ngaphansi "kokufundwa okuvamile."
3. Ugibe Lokushisa Kwesizini
Ngokwanda kwezinga lokushisa elingu-1°C, i-metabolism yezinhlanzi ikhuphuka ngo-10%, okwandisa isidingo se-oxygen. Uma abalimi bengalungisi amazinga okuphakela ngesikhathi sokufudumala kwentwasahlobo, ukudla okweqile kuholela ekukhuphukeni okukhulu kwe-COD. Izinhlelo ezingu-5-in-1 zibala ngokuzenzakalelayo izici zokunciphisa izinga lokushisa, zinikeze imikhawulo yesixwayiso esiguquguqukayo.
4. Ukuqhuba: I-Sentinel Yokungcola Kwangaphandle
Esigamekweni sokungcola eGuangdong ngo-2023, inzwa yokudlulisa amanzi yaqala ukubona ukuvuza kwamanzi amdaka evela efektri eseduze, yanikeza umlimi isikhathi esiphuthumayo samahora angu-8 futhi yavimbela ukufa kwamathani angu-200 e-perch.
Ukuthuthuka Kwezobuchwepheshe: Indlela Izinzwa Ezi-5-in-1 Ezakha Kabusha Ngayo I-Logic Yokuqapha Ukufuywa Kwezinhlanzi
Kusukela Kumaphuzu Edatha Awodwa Kuya 'Ezimpawu Ezibalulekile' Zesistimu Yezinto Eziphilayo
Isizukulwane esisha sezinzwa ezingu-5-in-1 akusikho ukuhlanganiswa nje; zisebenzisa ama-algorithms alungiselelwe ukufuywa kwezinhlanzi ukuze kufezwe ukuhlangana okuhlakaniphile phakathi kwamapharamitha:
I-Algorithm Eyinhloko: Inkomba Yengozi Yamanzi (i-WRI)
umbhalo
I-WRI = 0.35×COD_Trend_Coefficient + 0.25×DO_Decline_Rate +
0.20×pH_Anomaly_Score + 0.15×Ukwehluka_Kwezinga Lokushisa +
0.05 × Ukuqhuba_Ukuhamba_Kwe-Spike_Coefficient
Uma i-WRI > 0.7, uhlelo lucindezela ngokuzenzakalelayo izaziso ezinobungozi obukhulu ngemininingwane ethile.
Idatha yokuhlolwa kwensimu evela enkampanini yezobuchwepheshe bezolimo zaseNorway i-AquaSense ikhombisa ukuthi le algorithm inikeza isikhathi sokuxwayisa esimaphakathi samahora angu-38 ezifweni ezivamile, kanye nokucaciswa kwezifo zamagciwane (njenge-vibriosis) kufinyelela ku-89%.
Ukusekelwa Kwezinqumo Zesikhathi Sangempela Zokulima Okunembile
Epulazini lezinhlanzi eziqinile ePattaya, eThailand, uhlelo lwe-5-in-1 luvumela impendulo yezigaba ezintathu:
Isexwayiso Esiphuzi (WRI 0.5-0.7): Lungisa umoya, nciphisa ukudla
Isexwayiso Esiwolintshi (WRI 0.7-0.85): Ukushintshana kwamanzi okuyingxenye, engeza ama-probiotic
Isexwayiso Esibomvu (WRI > 0.85): Ukushintshana kwamanzi okuphuthumayo, qala ukwelashwa
Lolu hlelo lusize ipulazi ukunciphisa ukusetshenziswa kwama-antibiotic ngo-67% futhi lwandise ukusinda kwezithombo ze-shrimp ngo-22% phakathi nesizini ka-2023-2024.

Amacala Okusetshenziswa Komhlaba Wonke: Impumelelo Kusukela Ku-Salmon Kuya Ku-Eel
Ukulawulwa Okunembile Ekulimeni Kwe-Norwegian Deep-Sea Salmon
Isikhulu se-salmon emhlabeni wonke iMowi sathumela izinhlelo ezingu-5-in-1 emapulazini angu-20 ngo-2023. Ngokuqapha isilinganiso esithile phakathi kwe-COD ne-DO, uhlelo lubikezele ngempumelelo u-93% wezehlakalo zenhlekelele yomoya-mpilo, kunciphisa ukufa kwe-salmon kusuka esilinganisweni semboni esingu-3.2% kuya ku-1.4%. Lokhu kukodwa kusindisa inkampani cishe u-$45 million ngonyaka ekulahlekelweni okugwenywe.
Impumelelo Ekulimeni Ama-eel Fry aseJapan
Ama-eel fry azwela kakhulu ezinguqukweni zemvelo, kanti amazinga okusinda endabuko avame ukuba ngaphansi kuka-35%. Ngemva kokwethula uhlelo lwe-5-in-1, i-Nagasaki Prefectural Fisheries Research Institute ithole izinga lokusinda elingu-61% ngokugcina ngokunembile i-COD ngaphakathi kuka-8-15 mg/L kanye ne-DO ngaphakathi kuka-6.5-7.2 mg/L—“uhla lwegolide”—ukubeka irekhodi elisha lemboni.
Ukuthuthukiswa Kwekhwalithi Yenkala YamaShayina
Izilingo ezenziwe yiYangcheng Lake Crab Farmers Association zibonise ukuthi amachibi aqashwe ngohlelo lwe-5-in-1 akhiqiza izinkalankala ezinobukhulu obuphakathi obungu-18% kanye nesilinganiso sokugcwala kwenyamazane esingaphezulu ngo-27%. Ngo-2023, lezi nkalankala “ezifuywa ngedatha” zathola iprimiyamu yentengo engu-32% endalini.

Ukungena Kwemakethe
Izindleko zezinzwa ze-5-in-1 kulindeleke ukuthi zehle ngo-15-20% minyaka yonke.
Ngo-2028, ama-50% amapulazi omhlaba wonke azosebenzisa ukuqapha kwamapharamitha amaningi.
Amamodeli e-Sensor-as-a-Service (SaaS) azokwehlisa isithiyo sokwamukelwa kwabalimi abancane.
Imibono Yochwepheshe: 'Isikhathi Esisha Sedijithali Sokuzulazula' Kwezolimo Zasemanzini
“Singena ‘eNkathini Entsha Yedijithali Yokuzulazula’ kwezolimo zasemanzini,” kusho uGeorge Chamberlain, uMongameli we-World Aquaculture Society. “Esikhathini esidlule, besizulazula emanzini ngokuhlangenwe nakho. Manje, izinzwa ezi-5-in-1 zisinika ‘amashadi ekhwalithi yamanzi’ aqondile kanye ‘namakhampasi esixwayiso sakuqala.’ Lokhu akusikho nje ukusungula izinto ezintsha kwezobuchwepheshe kodwa kuyinguquko yezindlela zokukhiqiza izolimo zasemanzini.”
UDkt. Alisha Chen, usosayensi oyinhloko e-TurtleTree Aqua Lab yaseSingapore, wanezela: “Umncintiswano eminyakeni emihlanu ezayo ngeke usaphathelene nobukhulu kodwa uzophathelene nokunemba kwedatha kanye nesivinini sokuphendula. Abalimi abakwaziyo futhi benze ukungenelela okunembile bazowina imakethe kanye nenzuzo.”
Isiphetho: Ukushintsha Kwendlela Yokuphila Kusukela 'Ekwelapheni Ukulima' Kuya 'Ekulimeni Okuvimbelayo'
Izinhlelo zokuqapha ezihlakaniphile, eziboniswe yinzwa ye-COD engu-5-in-1, ziphawula ukuguquka kokufuywa kwezinhlanzi kusukela “ekwelashweni kwezifo” okungenamsebenzi kuya “ekuvimbeleni impilo” okusebenzayo. Yonke into engavamile yekhwalithi yamanzi kanye nenkinga ngayinye yezolimo egwenywe ngempumelelo ibumba kabusha ikusasa lale mboni yasendulo.
Uma abalimi bekwazi “ukuqonda” ukukhishwa kwamanzi, abasabi “izimpumputhe” ezilwa kodwa “abaholi” abakwazi ukubona izinguquko kusengaphambili nokuhamba ngokunembile. Kulesi sikhathi sokungaqiniseki, ukuphathwa kokunemba okuqhutshwa idatha sekuba ithuluzi elithembeke kakhulu kwezolimo zasemanzini lokunciphisa ubungozi kanye nokuphepha kokudla.
Singaphinde sinikeze izixazululo ezahlukahlukene ze
1. Imitha ephathwayo yekhwalithi yamanzi enamapharamitha amaningi
2. Uhlelo lwe-Floating Buoy lwekhwalithi yamanzi enamapharamitha amaningi
