Ingabe enye inempilo kunomunye?
Unyaka ngamunye, i-United States ingenisa cishe amaphesenti angama-90 ezinhlanzi esizidlayo. Lokhu kusho ukuthi iningi lezinhlanzi ozibonayo etafuleni lakho livela kwenye indawo futhi kungenzeka ukuthi ungazi ukuthi ngabe kuhlwanyelwe yini noma kubanjwe zasendle. Kusukela ekuboneni okunomsoco, akekho umehluko omkhulu phakathi kwezinhlobo ezimbili zezinhlanzi, ngakho-ke ukukhetha kwakho phakathi kwezinhlanzi ezifakiwe noma zasendle ezizobanjwa kuzoba nezindaba eziphathelene nezomnotho noma ezemvelo.
Ukubukwa Kwezinhlanzi Zama-Wild Caught
Izinhlanzi ezibanjwe zasendle zihlanganisa zonke izinhlanzi nezilwane zasolwandle ezitholwe ngamanetha, izicupho, noma ngemigqa yokudoba. Abantu baye bavuna izinhlanzi zasendle nezilwane zasolwandle iminyaka eyizinkulungwane, futhi empeleni, izinhlanzi nezigobolondo zibhekwa njengezinsiza ezivuselelekayo ngoba ngaphansi kwezimo ezijwayelekile zingakwazi ukugcwalisa izilwane zazo ngokwemvelo.
Kodwa-ke, inkinga ukuthi ukunyuka kwesidingo sezinhlanzi nezilwane zasolwandle kubangela ukudoba ngokweqile kwenzeke. I-Oceanic ne-Atmospheric Administration ibuka ama-fishery e-United States futhi isebenzisa izindlela zesayensi zokuphatha izinhlanzi ukuvimbela ukudoba. Ngokuqinisekile lokho kuyinto enhle, futhi enye indlela yokusiza ukusekela izinhlanzi zasendle ukukhulisa ukutholakala kwezinhlanzi ezilinywa.
Izinzuzo Zezinhlanzi Ezihlanziwe
Izinhlanzi ezihlwanyelwe zikhuliswe ezindaweni ezihlanganisiwe noma amathangi. Cishe isigamu sezilwane zasolwandle esidliwe emhlabeni jikelele sivunyiwe epulazini. Ngokusho kwe-Eat Wisconsin Fish, inhlangano yokuhweba yabalimi bezinhlanzi zaseWisconsin, i-aquaculture (igama elipholile lokulima izinhlanzi) yindlela ekhula ngokushesha yokukhiqiza ukudla emhlabeni.
I-China ibamba inamba eyodwa ekukhiqizeni kwamanzi kanye nama-US angu-13, kanti i-catfish ne-trout yiyona inhlanzi enkulu yaseMelika ehlwanyelwe.
Ukudoba okulimalayo kungase kuzuze ngoba kungathatha izingcindezi ezindaweni ezingaphezu kwezinhlanzi futhi kuvumele ukubuya kwezinhlanzi zasendle eziphelile. Izinhlanzi ezifuywayo, njenge-saumoni, zingaba zikhudlwana kuma-omega-3 fatty acids uma kuqhathaniswa nomzala wabo wesango, uma nje besondla kuqukethe izinhlanzi ze-omega-3.
Iyini i-Downside ye-Fish Farm?
I-Aquaculture ingasenomthelela emvelweni. Nakuba ukulima kwezinhlanzi e-US kulawulwa, akusilo iqiniso kuwo wonke amanye amazwe. Njengoba i-US ingenisa izinhlanzi eziningi, kunzima ukwazi ukuthi inhlanzi oyithenga ivela 'epulazini' eqhubekayo noma cha. Kuze kube khona ukunambitheka nokuthungwa, kungase kube khona umehluko omncane ngenxa yezinhlobo zokudla ezinikezwa inhlanzi ehlwanyelwe, kodwa lokho akusiyo impela, umahluko nje.
Ukuqhathanisa okunempilo
Kungase kube khona umehluko omncane wokudla okunomsoco phakathi kwezinhlanzi ezifakiwe nezilwane zasendle, kodwa hhayi okwanele ukumemezela owodwa noma omunye okunye okungahambi kahle. Isibonelo, uma uqhathanisa iphrofayili yokudla okunomsoco wezinhlanzi ezisetshenziselwa ukulimala, uzothola i-catfish yasendle ine-vitamin D engeziwe ne-potassium, kodwa inhlanzi ehlwanyelwe inamafutha amaningi e- polyunsaturated . I-catfish yasendle ine-protein encane kakhulu futhi ifama inezinhlamvu eziningana, kepha kuzo zonke, inhlanzi yinto enhle enempilo yokudla ukudla.
Endabeni ye-saumoni, i-saumon eluhlaza e-Atlantic ehlwanyelayo inamafutha amaningi we-polyunsaturated, kuhlanganise ne-eicosoapentaenoic acid (i-EPA) encane kune-salmon eluhlaza. Ibuye ibe nama-calories ambalwa.
I-salmon yasendle engama-3 inezingqikithi ezingu-121 uma kuqhathaniswa nama-ounces amathathu e-salmon epulazi enama-177.
Yikuphi Ukudoba Okuphephile?
Enye yezinto ezibaluleke kakhulu ekudleni ukudla kwezinhlanzi kungabangela ukungcola kwe-mercury. Kodwa izinhlobo ezithandwa kakhulu ezinkingeni ze-mercury zinkulu, izinhlanzi ezindala. I-Swordfish, i-tilefish, i-shark, ne-king mackerel yizinhlanzi okungenzeka zibe nezinqwaba ze-mercury, kuyilapho ipulazi ephakamisa i-fishfishfish, i-salmon, ne-trout ingase ingakhathazeki.
Izwi elivela
Ngaphandle kokuthi ungumuntu we-vegan noma wemifino, kubalulekile ukufaka inhlanzi nezinhlanzi eziningi ekudleni kwakho ngoba ziphezulu amaprotheni, i- zinc , namafutha enempilo ngaphandle kokuphakama kwamakholori namafutha agcwele.
Zombili izinhlanzi ezivuthwe futhi zasendle ezibanjwe zasendle ziyizinqumo ezinhle zokudla okunomsoco, ukukhetha okungahle ufune ukukwenza kuyobe kuncike emibonweni yakho emvelweni nokusimama. I-Monetary Bay Aquarium Seafood Watch iyinhlangano enhle kakhulu yokuncoma izinhlanzi zasolwandle kanye nemvelo.
