Okuphakelayo esikhundleni salmon!! Lesi yiseluleko sezazi

Ososayensi banikeze iseluleko esiyinqaba kubathandi bokudla izinhlanzi, ikakhulukazi i-salmon, ukuba badle ukudla kwayo, ikakhulukazi njengoba iqukethe izinhlanzi ezincane ze-salmon.

Ososayensi baseNyuvesi yaseCambridge bahlaziye idatha evela ekukhiqizeni ama-salmon afuywa ngo-2014 eScotland ukuze baqhathanise usayizi wezinhlanzi ezibanjwe endle nosayizi we-salmon efuywayo evunwa, kubika i-New Atlas.

Bathole ukuthi ngo-2014, amathani angu-460 ezinhlanzi zasendle asetshenziselwa ukukhiqiza amathani angu-179 e-salmon.

Ngaphezu kwalokho, amaphesenti angu-76 ezinhlanzi ezidotshwa endle ayeyizinhlobo ezivame ukudliwa abantu, njengama-anchovies namasardine.

Ngokuhlaziya lezi zibalo emhlabeni wonke, ososayensi balinganisela ukuthi uma izinhlanzi ezidotshwa olwandle nezilwandle zingase zisetshenziswe njengokudla kwabantu esikhundleni sokuba zisetshenziswe njengoba kwenzeka manje ekuphakeleni ama-salmon, cishe amathani ayizigidi ezine ezinhlanzi, okuyizinto ezisetshenziswayo. okwamanje zibanjwa olwandle unyaka ngamunye, zingashiywa unyaka, bese zizoba zikhudlwana futhi zibe umthombo otholakala njengokudla komuntu.

ezokudoba emhlabeni jikelele

Kulolu cwaningo, imiphumela yalo eshicilelwe kuphephabhuku i-PLOS Sustainability and Transformation, abacwaningi bayavuma ukuthi izibalo zabo zisekelwe ekukhiqizeni ama-salmon ezweni elilodwa esikhathini esingangonyaka owodwa, ngakho ucwaningo oluningi luzodingeka lwenziwe ngezinga elikhulu, nakuba wayekholelwa ukuthi izifundo ezilandelayo zizopenda isithombe esifanayo.

Baphinde bangeza ngokuthi "ukuvumela ukwanda kokukhiqizwa kwe-salmon ngokusebenzisa indlela yamanje kuzobeka ingcindezi engavamile esitokweni sezinhlanzi emhlabeni wonke."

Imiphumela iphakamisa ukuthi ukunciphisa umthamo wezinhlanzi zasendle ezisetshenziselwa ukukhiqiza ukudla kwe-salmon efuywayo kungase kunciphise ukucindezela kwezinhlanzi zasendle kuyilapho kwandisa ukutholakala kwezinhlanzi zasendle ezinomsoco ukuze zidliwe abantu.
