Izinhlanzi nezilwane zasemanzini

Izinhlanzi nezinye izilwane zasemanzini zakha iqembu elikhulu lezilwane ezibulawelwa ukudla, nokho ngokuvamile yizo ezinganakwa kakhulu. Izigidigidi ziyabanjwa noma zilinywe unyaka ngamunye, ezedlula kude izinombolo zezilwane zasemhlabeni ezixhashazwayo kwezolimo. Naphezu kobufakazi obandayo besayensi bokuthi izinhlanzi zizwa ubuhlungu, ukucindezeleka, nokwesaba, ukuhlupheka kwazo akunakwa noma azinakwa. I-Industrial aquaculture, evame ukubizwa ngokuthi ukufuywa kwezinhlanzi, ifaka izinhlanzi ezibayeni noma emakhejini aminyene lapho izifo, ama-parasites, nezinga eliphansi lamanzi lidlangile. Izinga lokufa liphezulu, futhi labo abasindayo babekezelela izimpilo zokuvalelwa, bencishwa ikhono lokubhukuda ngokukhululeka noma ukuveza ukuziphatha kwemvelo.
Izindlela ezisetshenziswayo ukubamba kanye nokubulala izilwane zasemanzini ngokuvamile zinonya ngokwedlulele futhi zithatha isikhathi eside. Izinhlanzi ezibanjiwe zasendle zingase ziminyaniswe kancane ezitezini, zichotshozwe ngaphansi kwamanetha asindayo, noma zife ngenxa yokuwohloka njengoba zidonswa emanzini ajulile. Izinhlanzi ezifuywayo zivame ukuhlatshwa ngaphandle kokumangalisa, zishiywe ukuze ziphefumule emoyeni noma eqhweni. Ngaphandle kwezinhlanzi, izigidigidi zama-crustaceans nama-mollusk—njengezimfanzi, izinkalankala, nezingwane—nazo zingenwa imikhuba ebangela ubuhlungu obukhulu, naphezu kokuqashelwa okwandayo kwemizwa yazo.
Umthelela wemvelo wokudotshwa kwezimboni kanye nokufuywa kwezilwane zasemanzini ulimaza ngokufanayo. Ukudoba ngokweqile kusongela zonke izimiso zemvelo, kuyilapho amapulazi ezinhlanzi anengxenye ekungcoleni kwamanzi, ekucekeleni phansi kwezindawo ezihlala kuzo, nasekusakazekeni kwezifo kubantu basendle. Ngokuhlola usizi lwezinhlanzi nezilwane zasemanzini, lesi sigaba sinikeza ukukhanya ezindlekweni ezifihlekile zokusetshenziswa kwezilwane zasolwandle, sikhuthaza ukucatshangelwa ngokujulile kwemiphumela yokuziphatha, imvelo, kanye nezempilo yokuphatha lezi zidalwa ezizwelayo njengemithombo engasetshenziswa.

Ukulima kwasefekthri sekuyindlela ehamba phambili yokukhiqiza inyama, eqhutshwa isidingo senyama eshibhile nenala. Kodwa-ke, ngemuva kokunethezeka kwenyama ekhiqizwa ngobuningi kukhona iqiniso elimnyama lonya nokuhlupheka kwezilwane. Esinye sezici ezicindezela kakhulu zokulima efektri ukuvalelwa ngonya kwezilwane eziyizigidi ngaphambi kokuba zibulawe. Lesi sihloko sihlola izimo ezinonya ezibhekene nezilwane ezifuywa efekthri kanye nemithelela yokuziphatha yokuvalelwa kwazo. Ukwazi izilwane ezifuywayo Lezi zilwane, ezivame ukufuyelwa inyama yazo, ubisi, amaqanda, zibonisa ukuziphatha okuhlukile futhi zinezidingo ezihlukile. Nakhu okufingqiwe kwezilwane ezifuywayo ezivamile: Izinkomo, njengezinja esizithandayo, zijabulela ukutotoswa futhi zifuna ukuxhumana nabanye izilwane. Endaweni yazo yemvelo, zivame ukwakha ubuhlobo obuhlala njalo nezinye izinkomo, njengobungane bokuphila konke. Ukwengeza, baba nothando olujulile ngamalungu omhlambi wabo, babonise usizi lapho ...

Izinhlanzi ziyizidalwa ezifunwa zikwazi ukuzwa izinhlungu, iqiniso liyaqhubeka liqinisekiswe ubufakazi besayensi bokuthi basuse izinkolelo eziphelelwe yisikhathi. Ngaphandle kwalokhu, izimboni zasemanzini nasezindlandla zasolwandle zivame ukungakunaki ukuhlupheka kwazo. Kusuka emapulazini ezinhlanzi axutshwe nezindlela zokubulala ngesihluku, izinhlanzi ezingenakubalwa zikhuthazelela usizi olukhulu nokulimaza impilo yazo yonke. Lo mbhalo wembula amaqiniso angemva kokudla kwasolwandle - ukuhlola isayensi yokuqonda izinhlanzi, izinselelo zokuziphatha zezenzo zokulima ezijulile, kanye nemiphumela yezemvelo eboshelwe kulezi zimboni. Icela abafundi ukuthi baphinde bacabange izinqumo zabo kanye no-Advocate ukuthola izindlela eziningi ezinobuntu nezizinzile empilweni yamanzi

Izigidi zezidalwa zasolwandle zibhajwe emjikelezweni wokuhlupheka embonini eyandayo ye-aquaciulture, lapho izimo eziningi kakhulu futhi zinganaki inhlala-kahle yazo. Njengoba ukufunwa kwasolwandle kukhula, izindleko ezifihliwe - izinkinga zokuziphatha okuhle, ukonakaliswa kwemvelo kanye nemithelela yezenhlalo - ziya ngokuya zibonakalayo. Lo mbhalo usikhanyisela ngokoqobo okunzima okubhekene nempilo yasolwandle engozini, kusuka ezindabeni zempilo yomzimba ekucindezelekeni kwengqondo, ngenkathi kufonela ushintsho olunenjongo ukudala i-aquaculture futhi eqhubekayo ye-aquaculture

Esikudlayo kungaphezu nje kokukhetha komuntu siqu - kuyisitatimende esinamandla mayelana nokuziphatha kwethu kokuziphatha, umthwalo wemfanelo wezemvelo, kanye nendlela esiphatha ngayo ezinye izidalwa eziphilayo. Izinkinga zokuziphatha zokudla imikhiqizo yezilwane nezilwandle zisiphoqe ukuba sihlole izindaba ezinjenge-Factory Farming, ukulimala kwemvelo yasolwandle, nokushintsha kwesimo sezulu. Ngokuqwashisa okukhulayo ezungeze inhlala-kahle yezilwane kanye nemikhuba esimeme, eceleni kokukhuphuka kwezindlela ezisekelwe kwezitshalo, le ngxoxo isikhuthaza ukuthi sicabange kabusha ukuthi imikhuba yethu yokudla ithonye nezethu seplanethi yethu kanye nenhlala-kahle yethu

Isidingo esikhulayo sokudla kwasolwandle siligqugquzele i-aquaculture embonini echumayo, kepha inhlala-kahle yezinhlanzi ezilimazeke ivame ukuhlala yanda kwande. Ihlanganiswe namathangi agcwele kakhulu ngokucebisa okulinganiselwe, lezi zilwane zibhekene nengcindezi, ukuqubuka kwezifo, kanye nempilo ehlehlisiwe. Lo mbhalo usikhanyisela ngesidingo esicindezelayo sezindinganiso ezingcono ekulimaleni kwezinhlanzi, uqokomisa izinselelo zemikhuba yamanje ngenkathi uhlola ezinye izindlela ezizinzileyo nezokuziphatha. Thola ukuthi izinketho ezinolwazi kanjani neziqondiso ezinamandla ezingasiza ekuguquleni i-waquaculture ibe umzamo onobuhlungu obuningi nomthwalo wemfanelo

Uma kukhulunywa ngokuzitika ngemikhiqizo yasolwandle ewubukhazikhazi njenge-caviar nesobho lika-shark fin, intengo idlulela ngalé kwalokho okuhlangabezana nokunambitha. Eqinisweni, ukudla lezi zibiliboco kuza nesethi yezimiso zokuziphatha ezingenakuzitshwa. Kusukela kumthelela wemvelo kuya onyameni lokukhiqizwa kwazo, imiphumela emibi ifinyelela kude. Lokhu okuthunyelwe kuhlose ukuhlolisisa izimiso zokuziphatha eziphathelene nokusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi, kukhanyiselwe ngesidingo sezinye izindlela ezisimeme kanye nokukhetha okufanele. Umthelela Wezemvelo Wokudla Imikhiqizo Yasolwandle Ewubukhazikhazi Ukudoba ngokweqile kanye nokucekelwa phansi kwemvelo okubangelwa ukusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi njenge-caviar nesobho lika-shark fin kunemithelela enzima yemvelo. Ngenxa yesidingo esikhulu salezi zinto zokudla zasolwandle eziwubukhazikhazi, izinhlanzi ezithile kanye nemvelo yasolwandle kusengcupheni yokuwa. Ukusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi kunomthelela ekuncipheni kwezinhlobo zezilwane ezisengozini futhi kuphazamisa izinto ezithambile…

Ukulima kwasefekthri kuyimboni efihlwe kahle, embozwe imfihlo futhi evimbela abathengi ukuthi baqonde izinga langempela lonya olwenzeka ngaphandle kweminyango evaliwe. Izimo zamapulazi ezimboni zivame ukuminyana, azihlanzekile, futhi zingenabuntu, okuholela ekuhluphekeni okukhulu kwezilwane ezihilelekile. Uphenyo kanye nezithombe eziqoshiwe ziveze izehlakalo ezishaqisayo zokuhlukunyezwa kwezilwane nokunganakwa emapulazini efektri. Abameli bamalungelo ezilwane basebenza ngokuzikhandla ukuze baveze iqiniso elimnyama lokulima kwasefekthri futhi bamelele imithetho eqinile kanye nezindinganiso zenhlalakahle yezilwane. Abathengi banamandla okwenza umehluko ngokukhetha ukweseka izindlela zokulima ezinokuziphatha nezisimeme esikhundleni sokulima kwasefemini. Izingulube emapulazini ezimboni zivame ukuhlala ngaphansi kwezimo ezizibeka ekuhluphekeni okukhulu ngenxa yengcindezi, ukuvalelwa, kanye nokuntuleka kwezidingo eziyisisekelo. Ngokuvamile zigcinwa ezindaweni eziminyene, ezingenalutho ezingenazo izingubo zokulala ezifanele, umoya omncane, noma igumbi lokubonisa impatho yemvelo efana nokuqeda izimpande, ukuhlola, noma ukuzijabulisa. Lezi…
