La ukuqhuba lisebe le lwamanzi, ekhethekileyo ekufuyweni kweentlanzi. Lo msebenzi unokwenziwa kumanzi olwandle kunye nakumanzi acwengileyo, ngokusetyenziswa kwamachibi okanye iminatha edadayo, ukunika enye indlela ezinzileyo yokuloba ngokwesintu. ukufuya iintlanzi Ivumela iintlobo ezahlukeneyo ukuba zikhuliswe kwiindawo ezilawulwayo, ukuphucula imveliso kunye nokuqinisekisa impendulo eyaneleyo kwimfuno ekhulayo yeentlanzi.
Ukufuywa kweentlanzi kubandakanya iintlobo ngeentlobo zeentlobo, ezifana ne-sea bream, i-sea bass, isalmon, kunye nenyamakazi. Ngaphezu koko, iintlobo ezifana ne-tuna zityetyiswa ekuthunjweni, nangona zingalinywanga ngendlela efanayo, ngenxa yokungabikho kobuchule bokulawula ukuzala kwezi ntlobo. Ukwenza oku, imizekelo yasendle iyabanjwa kwaye emva koko ivalelwe ukuze ityetyiswe de ifikelele kubungakanani obunqwenelekayo ukuze ithengiswe kamva.
Imbali yokuLinywa kweentlanzi
Ukufuya iintlanzi a uqheliselo lweminyaka eliwaka, eyayisele isetyenziswe kumaXesha Aphakathi, xa yamkelwa yimizi yeemonki yaseYurophu ukuqinisekisa ukunikezelwa kweentlanzi ngexesha leentsuku xa ukutya inyama kwakungavumelekanga, njengoLwesihlanu olungileyo. Ngaphaya kwemvelaphi yako yonqulo, ukufuywa kweentlanzi kwasasazeka, yaye namhlanje kuyinxalenye ebalulekileyo yemveliso yasemanzini yale mihla.
Namhlanje, le ndlela ibonelela ngesisombululo kwimfuno ekhulayo yeentlanzi, ngaloo ndlela ithintela ukuloba ngokugqithisileyo nokukhusela ubutyebi bendalo. Ukufuywa kweentlanzi kule mihla iye yahlukahlukana, iphuhlisa ubuchule bokuqhuba ukulima kwiindawo ezahlukeneyo, emanzini kunye namanzi ahlambulukileyo, kugxininise ekuzinzeni kunye nokunakekelwa kokusingqongileyo.
Iindlela zale mihla zoBuchule bokuFama iintlanzi
Namhlanje, ukufuywa kweentlanzi kusetyenziswa iindlela ezahlukeneyo ezithe zaqhelaniswa neemfuno zecandelo kunye neenkcukacha zeentlobo ezahlukeneyo zeentlanzi. Phakathi kweendlela eziphambili, sifumana oku kulandelayo:
- Iinkqubo zeCage: Isetyenziswa kumachibi, emilanjeni okanye elwandle, apho iintlanzi zivaleleke kwiindlwana ezintywilayo xa zikhula. Le ndlela ivumela iimeko zendalo zentlanzi ukuba zixeliswe ngokuchanekileyo, nangona ivelisa inkunkuma kwaye inokuchaphazela kakubi i-ecosystem engqongileyo.
- Iinkqubo zamachibi ezilawulwayo: Aquka ukufakwa kwamachibi angengowamvelo apho iintlanzi zilinywa phantsi kolawulo olungqongqo lwezinto ezifana nokutya nomgangatho wamanzi. Le ndlela inokugcinwa ngakumbi, kodwa idinga umthamo omkhulu wamandla kunye nezixhobo zokusebenza.
- Recirculation Systems: Kwezi nkqubo, amanzi ajikeleza kumachibi apho iintlanzi zinyuswa khona ahlala ehluzwa kwaye asetyenziswe kwakhona. Yindlela ye-ecological ngakumbi, ngokunciphisa ukusetyenziswa kwamanzi, nangona ukuphunyezwa kwayo kufuna iteknoloji enzima kunye neendleko eziphezulu zokuqala.
UkuLinywa kweentlanzi kunye noZinzo
Enye yeenzuzo eziphambili zokufuywa kweentlanzi kukukwazi ukuba negalelo kwi nokuzinza. Ngokunika enye indlela yokuloba ngokwesithethe, kunciphisa uxinzelelo kwi-ikhosistim yokuloba, inceda ekulondolozeni izilwanyana ezisengozini yokuphela ngelixa ibonelela ngomthombo oqhubekayo weprotheyini kubemi behlabathi. Ngokukodwa, ukufuya iintlanzi ezilawulwa kakuhle kunokuba neenzuzo ezifana nezi:
- IsiZukulwana seNgqesho: Inceda uphuhliso loluntu oluselunxwemeni nolwasemaphandleni, apho iaquaculture inokunika imithombo emitsha yengqesho.
- Ukukhuthazwa koQoqosho lwaseKhaya: Ngokwakha ishishini eliphumelelayo nelizinzileyo, uqoqosho lwasekhaya nolwesizwe luyaxhaswa, ngakumbi kumazwe apho ukuloba ngokwemveli kungaseyiyo indawo enokusebenziseka ngokwezoqoqosho.
- Ukhuseleko lokutya: Ngokunyuka kwemveliso yeentlanzi zokusetyenziswa kwabantu, umthombo oqhubekayo wokutya okuneprotheyini uqinisekisiwe.
Izinto ezingeloncedo ngokuLinywa kweentlanzi
Nangona kukho iingenelo ezininzi, ukufuya iintlanzi kuneengxaki. Njengalo naluphi na uhlobo lwemveliso enzulu, ibandakanya uthotho lwe imiceli mngeni ezinokuba neziphumo ezibi kuzo zombini iintlanzi kunye nokusingqongileyo. Phakathi kweengxaki eziphambili sifumanisa:
- Ukusasazeka kweZifo: Ukukhulisa iintlanzi kwiindawo ezivaliweyo, ezinabantu abaninzi kunceda ukusasazeka kwezifo kunye nezifunxi-gazi. Oku kuyingxaki ngakumbi kwimeko ye-salmon kunye nosulelo lweentwala zolwandle.
- Ungcoliseko lwaManzi: Inkunkuma yeentlanzi, kunye nokusetyenziswa kwemichiza efana namayeza okubulala iintsholongwane, inokuphumela emanzini akufutshane, ibangele i-eutrophication, ephelisa ioksijini emanzini ize ibulale izinto eziphilayo zaselwandle.
- Impembelelo kubemi basendle: Iintlobo ezikhuliswa kwiifama zeentlanzi zinokubalekela kwiindawo zokuhlala zendalo, zikhuphisane neentlobo zendalo kunye nokuguqula inkqubo yendalo. Ukongezelela koku kukho imingcipheko yokungcoliseka kwemfuza okubangelwa kukunqumlana kwezilwanyana zasendle nezilinywayo.
Imingeni yokuLinywa kweentlanzi kwiNkulungwane yama-21
Owona mceli mngeni wokufuywa kweentlanzi kule mihla kukuhlanganisa ukukhula kwecandelo ngolawulo olunenkathalo lokusingqongileyo. Ukwamkelwa kobuchwephesha obutsha kubalulekile ukuphepha iingxaki ezivela kusetyenziso olumandla lwemithombo yobutyebi kunye nongcoliseko. Ezinye zezisombululo eziqwalaselwayo ziquka ukuphuculwa kweenkqubo zokujikeleziswa kwamanzi ukuze kuphuculwe ukusetyenziswa kwamanzi nokuqinisekisa ukuba inkunkuma ayichaphazeli indalo esingqongileyo.
Enye into ebalulekileyo yile ukuzinza kokutyiswa kweentlanzi, ekubeni iintlobo ezininzi ezikhuliswa kwiifama zeentlanzi zidla inyama kwaye zifuna ukusetyenziswa kweentlanzi zasendle njengokutya. Lo mjikelo unokunyuka kunokunciphisa uxinzelelo kushishino lwendalo lokuloba. Ke ngoko, kufunwa ukutsha kuphuhliso lokutya okusekelwe kwizityalo kunye nezinye izixhobo ezizinzileyo.
Ukufuywa kweentlanzi kubekwe njengempendulo esebenzayo kwimfuno yehlabathi yeemveliso zokuloba, kodwa kuyimfuneko ukuphumeza imilinganiselo yokunciphisa impembelelo yako engalunganga kokusingqongileyo nokuqinisekisa uzinzo lwexesha elide lwecandelo.
