Iyini Ithangi Lokufuya Izinhlanzi? Umhlahlandlela Wobunjiniyela Nokukhetha Kwe-Aquaculture Yesimanje
Ithangi lokufuya izinhlanzi (elivame ukubizwa ngokuthi i-aquaculture tank noma i-culture tank) liyisitsha esikhethekile esisemhlabathini esiklanyelwe ukuzalanisa, ukukhulisa, nokuvuna izinhlobo zasemanzini ngaphansi kwezimo zemvelo ezilawulwayo. Kusukela emathangini amancane okufukamela kuya emathangini amakhulu asezingeni lezohwebo asetshenziswa ezinhlelweni eziphambili zokuphinda usebenzise amanzi (RAS), lezi zitsha zinikeza ikhwalithi yamanzi elungiselelwe, ukulawula izinga lokushisa ngokunembile, nokususa udoti ngendlela efanele ukuze kukhiqizwe izinhlanzi ngendlela eqhubekayo.
Iqhaza Lamathangi Ezinhlelweni Zokuphinda Usebenzise Amanzi (RAS)
Ukufuya izinhlanzi ngendlela evamile emanzini avulekile kuziveza izinhlanzi ekungcoleni kwemvelo, izinambuzane (ezifana nezintwala zasolwandle), kanye nokushintshashintsha kwezinga lokushisa kwamanzi. Ngokuphambene, amathangi esimanje asemhlabathini okufuya izinhlanzi asebenza ngaphakathi komjikelezo ovaliwe lapho amanzi okufuya angaphezu kuka-90% ehlanjululwa, ehlanzwa, futhi ephinde asetshenziswe.
Ngaphakathi kwalolu hlelo oluhlanganisiwe, ithangi lezinhlanzi liyisikhungo esiyinhloko lapho ukondla, ukukhula, nokuqoqwa kukadoti kokuqala kwenzeka khona ngaphambi kokuba amanzi ampontshwe ngezihlungi zemishini yamadrum, izinqaba ze-biological nitrification, kanye nama-UV sterilizer.
Ukuqhathaniswa Kwezinto Zokwakha Zamathangi Okufuya Izinhlanzi
Ukukhetha into efanele yethangi kuthinta ngqo impilo yezinhlanzi, izindleko eziyimali, kanye nokuphila isikhathi eside kwesakhiwo:
Into Yethangi | Ukumelana Namakhemikhali Nokugqwala | Isikhathi Sokuphila | Ukukhula & Ukwakhiwa | Okufaneleka Kakhulu |
Ingilazi Ehlanganiswe Nensimbi (GFS) / Insimbi Ebotshiwe | Ubude besikhathi (Ingilazi engangenwa lutho imelana nosawoti kanye nama-asidi) | Iminyaka engu-30–50+ | Ukuhlanganiswa okusheshayo kwe-modular ngamabhawodi endaweni | Izindawo ezinkulu zokukhulisa ezentengiselwano kanye nezindawo ze-RAS |
IPlastiki Eqiniswe Nge-Fiberglass (FRP) | Phezulu (Alinakugqwala ngokuphelele) | Iminyaka engu-20–30 | Ukubunjwa okuyingxenye noma okwenziwe ngaphambilini | Izindawo zokufukamela, izindawo zokukhulisa izinhlanzi ezincane, kanye nokufuywa kwezinhlanzi zasolwandle |
Ukhonkolo Oqinisiwe | Okulingene (Idinga izinto zokuvikela ezingaphakathi) | Iminyaka engu-30+ | Ukuthululwa okudinga umsebenzi omningi endaweni (Okungashintshi) | Amafama ezilwane zasemanzini amakhulu kamasipala noma ezimbonini ezisindayo |
I-HDPE / Izinto Zokufaka Iplastiki | Kuhle (Kumelana namakhemikhali, kuyaguquguquka) | Iminyaka eyi-10–15 | Ukusetha okusheshayo; ukuqina okulinganiselwe | Imisebenzi emincane namachibi esikhashana |
Izici Eziyinhloko Zomklamo Wamathangi Okufuya Izinhlanzi Asebenza Kahle
Amathangi okufuya izinhlanzi ezentengiselwano kumele afake izinto ezithile zokwakheka nokuhamba kwamanzi ukuze kugcinwe impilo yezinhlanzi nokusebenza kahle:
● Izansi Eziyizingqungqulu Eziyihlanza Ngokwazo: Zakhiwe ngezansi elithambekele noma eliyikhoni engu-60-degree elisebenzisa ukugeleza okuzungezayo ukuze kugxilwe udoti oqinile (indle kanye nokudla okungadliwanga) uye emgodini ophakathi ukuze kukhishwe ngokushesha.
● Izindawo Ezingaphakathi Ezibushelelezi Ezingenazo Izimbotshana: I-vitreous enamel noma i-gel-coat finishes ivimbela ukunamathela kwe-algae, iqede izikhala ezincane lapho amagciwane anda khona, futhi ivimbele ukuklwebheka kwezikele zezinhlanzi.
● Ukuhlelwa Kwemigudu Yokungena Nokuphuma Okwenziwe Ngokwezifiso: Kuhlonyiswe ngamabhokisi okuvuna asemaceleni, izihluzi ezigcwele amanzi, nezihluzi eziphikisana ne-vortex ezilungiselelwe ukuminyana kwesitokwe kanye nezinhlobo zezinhlanzi.
● Ukunwetshwa Kwe-Modular: Imiklamo yamathangi ahlanganiswe ngamabhawodi avumela izikhungo ukuthi zikhuphule kalula umthamo wokukhiqiza noma zihambise amathangi njengoba izidingo zebhizinisi zishintsha.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo 1: Ithangi lokufuya izinhlanzi lisetshenziselwani?
Impendulo: Ithangi lokufuya izinhlanzi lisetshenziselwa ukufuya izinhlanzi emhlabathini nokutshala izinhlanzi. Linikeza indawo elawulwayo yokuchanyusela, ukunakekela, nokukhulisa izinhlobo zezinhlanzi ezithengiswayo (ezifana ne-tilapia, i-salmon, i-shrimp, ne-trout) ngenkathi kulawulwa ukuhlungwa kwamanzi, ukufakwa komoya-mpilo, kanye nemijikelezo yokondla.
Umbuzo 2: Yiziphi izinzuzo zamathangi e-Recirculating Aquaculture System (RAS)?
Impendulo: Amathangi e-RAS anikeza indawo elawulwa ngokuphelele enciphisa ukusetshenziswa kwamanzi (kusetshenziswa kabusha amanzi angaphezu kuka-90%), avikela izinhlanzi ezifweni nasezilwaneni eziyingozi zangaphandle, athuthukise ukusetshenziswa kokudla, futhi avumele ukufuywa kwezinhlanzi emaphandleni ngaphandle kokubheka izimo zezulu zendawo.
Umbuzo 3: Kungani amathangi e-Glass-Fused-to-Steel (GFS) ethandwa kakhulu ekufuyweni kwezinhlanzi okuhweba?
Impendulo: Amathangi e-GFS ahlanganisa amandla okuqina kwensimbi nokungasebenzi kwamakhemikhali engilazi encibilikisiwe. Anikeza ukumelana nokugqwala okungavamile emanzini ahlanzekile nawanosawoti, awadingi ukulungiswa (akudingi ukuphintwa upende), futhi ahlanganiswa ngokushesha ngamaphaneli e-bolted amojula.
UMBUZO 4: Imfucumfucu eqinile ikhishwa kanjani emathangini okufuya izinhlanzi?
Impendulo: Amathangi asebenzisa izindlela zokugeleza kwamanzi eziphucukile—ngokuvamile zisizwa ukuma okuyindilinga kwethangi kanye nezansi ezinethambeka—ukususa imfucumfucu eqinile iye emseleni ophakathi. Amanzi angcolile abe esedluliswa ngezihlungi eziyidrum ezisebenza ngomshini noma emabhasini okuhlala ukuze kugcinwe ikhwalithi yamanzi emsulwa.
