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.

Ukudla kwasolwandle sekunesikhathi eside kuyinsakavukela umchilo wesidwaba emasikweni amaningi, okuhlinzeka ngomthombo wokudla nokuzinza kwezomnotho emiphakathini egudle ugu. Kodwa-ke, ngokukhula kwesidingo sokudla kwasolwandle kanye nokwehla kwezinga lezinhlanzi zasendle, imboni isiphendukele ekulimeni izilwane zasemanzini - ukulima kwezilwane zasolwandle ezindaweni ezilawulwayo. Nakuba lokhu kungase kubonakale kuyisixazululo esimeme, inqubo yokulima ukudla kwasolwandle iza nesethi yayo yezindleko zokuziphatha nezemvelo. Eminyakeni yamuva nje, kuye kwaphakama ukukhathazeka mayelana nokuphathwa kahle kwezinhlanzi ezifuywayo, kanye nemithelela engemihle engaba khona ezinhlelweni zemvelo ezithambile zasolwandle. Kulesi sihloko, sizongena emhlabeni wokulima kwezilwane zasolwandle futhi sihlole izindaba ezahlukahlukene eziwuzungezile. Kusukela ekucatshangelweni kwezimiso zokuziphatha zokukhulisa izinhlanzi ekuthunjweni kuye emiphumeleni yemvelo yokusebenza kwezilwane zasemanzini ezinkulu, sizohlola iwebhu eyinkimbinkimbi yezinto ezidlalwa ohambweni olusuka olwandle luye kwelinye. …

Ulwandle luhlanganisa ngaphezulu kwama-70% omhlaba futhi luyikhaya lokuhlekisa ngempilo yasemanzini. Eminyakeni yamuva nje, isidingo sokudla kwasolwandle siholele ekukhuphukeni kwamapulazi olwandle namapulazi ezinhlanzi njengendlela yokudoba okuqhubekayo. Lawa mapulazi, abizwa nangokuthi ama-aquaculture, ajwayele ukubonwa njengesixazululo sokudoba ngokweqile nendlela yokuhlangabezana nesidingo esikhulayo sokudla kwasolwandle. Kodwa-ke, ngaphansi kobuso kukhona iqiniso elimnyama lomthelela lawa mapulazi anawo endalini yemvelo yasemanzini. Ngenkathi zingabonakala njengesixazululo ebusweni, iqiniso ukuthi amapulazi olwandle nama-fish angaba nemiphumela emibi emvelweni nasezilwaneni ezibiza ulwandle ekhaya. Kulesi sihloko, sizokwehla ngokujulile emhlabeni wolwandle kanye nokulima izinhlanzi futhi siveze imiphumela efihliwe esisongela imvelo yethu engaphansi kwamanzi. Ukusuka ekusetshenzisweni kwama-antibiotic nama-pesticides ku ...

I-Aquaculture, yayivame ukugujwa njengesixazululo sokudla okukhulayo komhlaba kwezindawo zasolwandle, kufihla okungaphansi kwangaphansi okudinga ukunakwa. Ngemuva kwesithembiso sezinhlanzi eziningi futhi ukuncipha kokudoba amanga akhona imboni ehlushwa ukubhujiswa kwemvelo nezinselelo zokuziphatha. Amapulazi agcwele kakhulu akhuthaza ukuqubuka kwezifo, kanti imfucuza kanye namakhemikhali angcolisa imvelo ethambile. Le mikhuba ayigcini ngokufaka engcupheni ukuhlukahluka kwezinto eziphilayo zasemanzini kodwa futhi iphakamise ukukhathazeka okukhulu ngenhlala-kahle yezinhlanzi ezifuywayo. Njengoba izingcingo zokuguqula izinguquko zikhula, le ndatshana ikhama ngamaqiniso afihliwe e-aquaculture futhi ihlole imizamo yokusimama okuwumpetha, ububele, kanye noshintsho olunenjongo yokuthi sixhumana kanjani nolwandle lwethu

Ukudla kwasolwandle kuyisisekelo sokudla komhlaba jikelele, kepha uhambo lwalo lokuya kwamapuleti ethu luvame ukuza ngezindleko ezifihliwe. Ngemuva kwesabelo se-sushi rolls kanye nezihlungi zezinhlanzi kulele embonini egcwele ukuxhashazwa, lapho ukwenziwa ngokweqile, imikhuba ebhubhisayo, nokuphathwa ngonya kwezilwane zasemanzini kuyinto evamile. Ukusuka emapulazini aqashile agcwele e-aquacauldies ku-bycatch ngokungakhethi amanetha amakhulu okudoba, izidalwa ezingenakubalwa ezinamandla zikhuthazelela ukuhlupheka okukhulu ngaphandle kokubona. Ngenkathi izingxoxo zezenhlalakahle zezilwane zivame ukuba phakathi kwezinhlobo ezisuselwa emhlabathini, impilo yasolwandle ihlala inganakwa kakhulu yize kubhekene nemibandela embi ngokulinganayo. Njengoba ukuqwashisa kukhula ngalezi zinkomba ezinganakwa, kukhona ucingo olukhuphukayo lwamalungelo ezilwane zasemanzini kanye nezinqumo zokudla kwasolwandle okuthe xaxa - ukunikela ngethemba kuzo zombili izimpilo zolwandle kanye nezimpilo abasekelayo

Isikhathi eside kakhulu, insumansumane yokuthi izinhlanzi azinakukwazi ukuzwa izinhlungu zilungiselele isihluku esisakazekile ekudobeni nasezindaweni ezifuywayo. Kodwa-ke, ukufaka ubufakazi besayensi ekwakhekeni okuhluke ngokuphelele: Izinhlanzi zinezinhlaka zemizwa kanye nezimpendulo zokuziphatha ezidingekayo zokubhekana nobuhlungu, ukwesaba, kanye nosizi. Emisebenzini yokudoba yokudonswa kwezentengiselwano ehlukumeza ama-aquacauture ahlala isikhathi eside agcwele izingcindezi nezifo, izigidigidi zezinhlanzi zikhuthazelela ukulimala okungacabangeki unyaka nonyaka. Le ndatshana ingena kwisayensi ngemuva kokudunwa kwezinhlanzi, iveze amaphutha okuziphatha kwalezi zimboni, futhi inselele ukuthi siphinde sicabange ubuhlobo bethu nokuphila kwasemanzini okubeka phambili inhlala-kahle yezilwane ngokuxhashazwa kwezilwane ngokweqile

Emthunzini wokulima efektri, inkinga efihlekile yenzeka ngaphansi kwezinhlanzi zamanzi, izidalwa ezinobuhlakani kanye nezinto ezihlakaniphile, zikhuthazele ukuhlupheka okungacabangeki ngokuthula. Ngenkathi izingxoxo eziphathelene nenhlalonhle yezilwane zivame ukugxila ezilwaneni zomhlaba, ukuxhashazwa kwezinhlanzi ngokudotshwa kwezimboni kanye ne-aquaculture kuhlala kunganakwa kakhulu. Uboshelwe ezimweni ezigcwele kakhulu futhi wavezwa amakhemikhali ayingozi kanye nokubhujiswa kwemvelo, lezi zidalwa zibhekana nonya olungapheli olunganakwa ngabathengi abaningi. Lo mbhalo uhlola ukukhathazeka ngokuziphatha, umthelela wemvelo, kanye nocingo oluphuthumayo ukuze aqaphele inhlanzi njengokufanele ukuvikelwa nobubele ezinhlelo zethu zokudla. Ushintsho luqala ngokuqwashisa-ake silethe usizi lwabo

I-Octopus Farming, impendulo ekufuneni kwasolwandle okukhuphuka kwasolwandle, iye yaveza impikiswano enkulu ngeMvelo yayo yokuziphatha nezemvelo. Lawa ma-cephalopods athakazelisayo awawumiswa kuphela ngokudluliswa kwawo kwe-Cullinary kodwa futhi ahlonishwa ubuhlakani bayo, ukuxazulula izinkinga, kanye nokujula ngokomzwelo - izimfanelo eziphakamisa imibuzo ebucayi ngokuziphatha okuhle. Ukusuka ekukhathazekeni ngenhlalonhle yezilwane ekucindezelweni okubanzi kwamalungelo ezilwane zasolwandle, le ndatshana ihlola ubunzima obuzungezile i-Octopus Aquaculture. Ngokuhlola umthelela wayo kwimvelo, ukuqhathanisa nemikhuba yokulima esekwe emhlabeni, futhi kudinga amazinga okulashwa okunobuntu, sibhekane nesidingo esiphuthumayo sokulinganisa ukusetshenziswa kwabantu ngenhlonipho yempilo yasolwandle enobuhlakani

Uhlelo lwethu lwamanje lokudla lunembangela yokufa kwezilwane zasemhlabeni ezingaphezu kwezigidi eziyisi-9 ngonyaka. Kodwa-ke, lesi sibalo esishaqisayo simane nje sikhomba ububanzi bokuhlupheka ohlelweni lwethu lokudla, njengoba sikhuluma ngezilwane zasemhlabeni kuphela. Ngaphezu kwamanani asemhlabeni, imboni yokudoba ibangela umonakalo odabukisayo ezilwaneni zasolwandle, ezibulala izigidi zezigidi zezinhlanzi nezinye izilwane zasolwandle unyaka ngamunye, ukuze zidliwe abantu ngokuqondile noma njengezingozi ezingahlosiwe zokudoba. I-Bycatch ibhekisela ekubanjweni kwezinhlobo okungahlosiwe ngazo ngesikhathi sokudoba ngenjongo yokudayisa. Lezi zisulu ezingahlosiwe zivame ukubhekana nemiphumela emibi, kusukela ekulimaleni nokufa kuya ekuphazamisekeni kwesimiso sezinto eziphilayo. Lesi sihloko sihlola izilinganiso ezihlukahlukene zokudotshwa kwezinhlanzi, okusikhanyisela ngomonakalo wesibambiso odalwe izinqubo zokudoba zezimboni. Kungani imboni yokudoba imbi? Imboni yokudoba ivamise ukugxekwa ngemikhuba embalwa enomthelela omubi kuzinto eziphilayo zasolwandle kanye…

Ekulimeni kwasefekthri, ukusebenza kahle kubekwa phambili ngaphezu kwakho konke okunye. Izilwane zivame ukukhuliswa ezindaweni ezinkulu, ezivalekile lapho zihlanganiswe ngokuqinile ukuze kwandiswe inani lezilwane ezingakhuliswa endaweni ethile. Lo mkhuba uvumela amazinga aphezulu okukhiqiza kanye nezindleko eziphansi, kodwa ngokuvamile kuvela ekulahlekelweni kwenhlalakahle yezilwane.Kulesi sihloko, uzothola konke odinga ukukwazi mayelana nemikhuba yokulima efekthri. Ukulima kwasefekthri e-United States kuhlanganisa izinhlobonhlobo zezilwane, ezihlanganisa izinkomo, izingulube, izinkukhu, izikhukhukazi nezinhlanzi. Izinkomo Izingulube Izinhlanzi Izikhukhukazi Izinkukhu Factory Farmed Chickens & Hens Factory ukufuywa kwezinkukhu kubandakanya izigaba ezimbili eziyinhloko: lezo ezikhuliselwa ukukhiqizwa kwenyama kanye nalezo ezisetshenziselwa izinjongo zokuzalela amaqanda. Impilo Yezinkukhu Zenyama Emapulazini Emboni Izinkukhu ezifuyelwa inyama, noma izinkukhu zenyama, zivame ukubekezelela izimo ezinzima empilweni yazo yonke. Lezi zimo zihlanganisa izindawo zokuhlala eziminyene futhi ezingahlanzekile, ezingase…

Izilwandlekazi, zigcwele impilo futhi zibalulekile ekulinganiseni kweplanethi yethu, zivinjezelwa ekushisweni ngokweqile nangamandla abhubhisayo - amabutho amabili abhubhisayo ashayela izinhlobo zasolwandle ekuweni. Ukudoba ngokweqile kuchithe izinhlanzi zabantu ngamanani angenakuvikeleke, ngenkathi u-bycatch ngokungabonakali izicupho ezibuthakathaka njengefudu lwasolwandle, amahlengethwa kanye nezinyoni zasolwandle. Le mikhuba ayiphazamisi kuphela i-Marine Ecosystems yaseManzini kodwa futhi isongela imiphakathi yasogwini okuncike ekujuleni kwezimpilo zokuziphilisa. Lo mbhalo uhlola umthelela omkhulu wale misebenzi ezinhlanganweni zezinto eziphilayo kanye nemiphakathi yabantu ngokufanayo, ebiza isinyathelo esiphuthumayo ngokusebenzisa izindlela zokuphatha zomhlaba kanye nokubambisana komhlaba wonke ukuvikela impilo yolwandle lwethu
