ISixeko saseMexico, nge-24 kaJulayi 2025 – Njengoko ukunqongophala kwamanzi kwihlabathi liphela kusanda, icandelo lezolimo laseMexico lisebenzisa izinzwa ze-optical dissolved oxygen (DO) ukuze kuphuculwe ulawulo lwe-aquaculture, kuncitshiswe ukusetyenziswa kwamandla, kwaye kuphuculwe amazinga okusinda kweentlanzi. Le teknoloji intsha isasazwe ngempumelelo kwiifama ezininzi, nto leyo ephucula kakhulu imveliso kunye nokuzinza kokusingqongileyo.
Isishwankathelo seTekhnoloji: Iingenelo zeeSensors ze-Optical DO
Ukufuywa kwezilwanyana zasemanzini kwendabuko kuxhomekeke kuvavanyo olwenziwe ngesandla okanye kwiinzwa ze-electrochemical ukujonga amanqanaba eoksijini enyibilikisiweyo, afuna ukulinganiswa rhoqo kwaye asengozini yokungcola. Ngokwahlukileyo koko, iinzwa zeoksijini enyibilikisiweyo ezibonakalayo zisebenzisa itekhnoloji yokucima i-fluorescence, ezibonelela ngeenzuzo eziphambili:
- Ukuchaneka okuphezulu: Uluhlu lokulinganisa oluphakathi kwe-0-50 mg/L kunye nomda wempazamo we-±0.1 mg/L kuphela (kwizinga eliphantsi), oluhambelana kakuhle neemeko zamanzi eziguquguqukayo zaseMexico.
- Ulondolozo oluphantsi: Izivalo zesensor zihlala ukuya kuthi ga kwiminyaka emi-2 ngaphandle kokulungiswa rhoqo, kwaye imisebenzi yokuzicoca inciphisa ukungcola.
- Ukubeka esweni ngexesha langempela: Ixesha lokuphendula ngokukhawuleza (T90 < imizuzwana engama-45), okuvumela ulawulo oluzenzekelayo lweenkqubo zomoya.
Isifundo seTyala: Ukuphunyezwa kwiifama zezilwanyana zasemanzini zaseMexico
Kwimisebenzi enzima yokulima iintlanzi kulo lonke elaseMichoacán naseSinaloa, kuye kwasetyenziswa iinkqubo zokubeka esweni i-DO engenazingcingo, eziquka ii-buoys ezisebenza ngamandla elanga, abalawuli bomoya, kunye nesoftware esekelwe efini. Iziphumo eziphambili ziquka:
- Ukonga amandla: Ulawulo lomoya oluzenzekelayo lunciphise ukusetyenziswa kombane ngama-30%.
- Ukusinda kweentlanzi okuphucukileyo: Amanqanaba e-oksijini azinzileyo (agcinwe kwi-5-7 mg/L) anciphise amazinga okufa ngama-20% kwaye andise ukusebenza kakuhle kokuguqulwa kokutya nge-15%.
- Ulawulo olukude: Abalimi bafumana izilumkiso ngexesha langempela ngezixhobo eziphathwayo, nto leyo enciphisa amaxesha okuphendula ngexesha likaxakeka ukusuka kwiiyure ukuya kwimizuzu eli-10 kuphela.
Impembelelo yoMgaqo-nkqubo kunye noQoqosho
Urhulumente waseMexico udibanise ukujonga umgangatho wamanzi akrelekrele kwiSicwangciso sakhe soPhuhliso lwezoLimo lweSizwe sika-2024-2030, enika izibonelelo zerhafu zokusetyenziswa kobuchwepheshe. Umzekelo, ifama yetilapia eJalisco ibike ukunyuka kwe-12% kwinzuzo yonyaka emva kokusebenzisa izinzwa ze-optical, ngelixa ikwanciphisa ilahleko ezivela ekuncipheni kwe-oxygen ngequbuliso.
Imbono Yekamva: Iingcali zicebisa ukudibanisa idatha yesathelayithi (njengokubeka esweni i-infrared thermal) kunye netekhnoloji yedrone ukuphuhlisa inethiwekhi yolawulo oludibeneyo "lwamanzi-umhlaba-imozulu", nto leyo eqhubela phambili ukufuywa kweentlanzi ngokuchanekileyo.
