Sekuyisikhathi eside ososayensi bekhathazekile ngokuthi i-goldfish ne-carp yegolide ehlobene nazo zingaphila kanjani isikhathi eside ngokungabikho okuphelele komoya-mpilo. Ekugcineni, impendulo yatholakala: iqiniso, njengoba kwavela, "linecala."
Njengoba wazi, i-goldfish, naphezu kwesimo sayo se-aquarium, ingeyenhlobo ye-carp. Ngasikhathi sinye, ukubukeka "okukhazimulayo" akubavimbeli ekuboniseni ukukhuthazela nobungqabavu obumangalisayo. Isibonelo, bayakwazi ukuhlala amasonto phansi kwesiziba esimbozwe yiqhwa, lapho umoya-mpilo ucishe ungabikho ngokuphelele.
I-carp yegolide, engahlala ezimweni ezinjalo izinyanga ezingaphezu kwezintathu, inekhono elifanayo. Ngasikhathi sinye, i-lactic acid kufanele iqoqane emzimbeni wazo zombili izinhlanzi, ezikhiqizwa ngobuningi ezimeni ze-anoxic, okufanele ziholele ekufeni kwasekuqaleni kwezilwane. Lokhu kufana nesimo lapho kushiswa izinkuni ngaphandle kokukhipha intuthu noma ukushisa.
Manje ososayensi bathole ukuthi lezi zinhlobo ezimbili zezinhlanzi zinekhono eliyingqayizivele elivame kakhulu phakathi kwamagciwane afana nemvubelo, kepha hhayi ejwayelekile yama-vertebrate. Leli khono kube yikhono lokucubungula i-lactic acid ibe ama-molecule otshwala, abese edonswa angene emanzini ngezinsimbi. Ngakho-ke, umzimba ulahla imfucuza ebeka impilo engcupheni.
Njengoba inqubo yokwakhiwa kwe-ethanol yenzeka ngaphandle kwe-mitochondria yeselula, utshwala bungasuswa masinyane emzimbeni, kepha busangena egazini, ngaleyo ndlela kube nomthelela ekuziphatheni kwezinhlanzi zegolide kanye nezihlobo zazo - i-crucian carp. Kuyathakazelisa ukuthi okuqukethwe utshwala egazini lenhlanzi kungadlula okujwayelekile, okuthi kwamanye amazwe kubhekwe njengomkhawulo wabashayeli bezimoto, okufinyelela kuma-50 mg we-ethanol nge-100 ml yegazi.
Ngokusho kososayensi, isixazululo esinjalo senkinga ngosizo lwendlela yokuqala yokuphuza sisengcono kakhulu kunokuqongelela i-lactic acid kumaseli. Ngaphezu kwalokho, leli khono livumela izinhlanzi ukuba ziphile ngokuphepha ezimweni ezinjalo, lapho ngisho nezilwane ezifuna ukuzuza ku-carp crucian zikhetha ukungabhukudi.
