Kwa nthawi yaitali asayansi akhala akuda nkhaŵa za momwe nsomba za golide ndi nsomba zawo zagolide zimakhalira kwa nthawi yayitali mulibe mpweya. Pomaliza, yankho linapezeka: chowonadi, monga momwe zinachitikira, "chiri cholakwa."
Monga mukudziwa, nsomba zagolide, ngakhale zili ndi aquarium, ndizamtundu wa carp. Nthawi yomweyo, mawonekedwe owoneka bwino samawalepheretsa kuwonetsa kupirira komanso mphamvu. Mwachitsanzo, amatha kukhala milungu ingapo pansi pa dziwe lodzaza ndi madzi oundana, momwe mpweya umasowa.
Golide wa carp, yemwe amatha kukhala m'malo oterewa miyezi yopitilira itatu, ali ndi kuthekera kofananako. Nthawi yomweyo, lactic acid iyenera kudziunjikira mthupi la nsomba zonse ziwiri, zomwe zimapangidwa mochuluka mikhalidwe yazowautsa, zomwe zimayenera kuyambitsa kufa kwa nyama. Izi zikufanana ndi momwe nkhuni zimawotchera popanda kutulutsa utsi kapena kutentha.
Tsopano asayansi apeza kuti mitundu iwiriyi ya nsomba ili ndi kuthekera kwapadera komwe kumakhala kofala pakati pa mabakiteriya monga yisiti, koma osakhala ofanana ndi mafupa am'thupi. Kutha kumeneku ndikuti ndikotheka kupanga ma lactic acid kukhala mamolekyulu a mowa, omwe amatulutsidwa m'madzi kudzera m'mitsempha. Chifukwa chake, thupi limachotsa zonyansa zomwe zimaika pachiwopsezo ku thanzi.
Popeza njira yopangira ethanol imachitika kunja kwa mitochondria yam'manja, mowa umatha kutulutsidwa m'thupi nthawi yomweyo, koma umalowabe m'magazi, motero umathandizira machitidwe a nsomba zagolide ndi abale awo - crucian carp. Ndizosangalatsa kuti zakumwa zoledzeretsa zomwe zili m'magazi a nsomba zimatha kupitilira muyeso, womwe m'maiko ena amawerengedwa kuti ndi malire a oyendetsa magalimoto, omwe amafikira 50 mg ethanol pa 100 ml yamagazi.
Malinga ndi asayansi, yankho lavutoli mothandizidwa ndi mtundu woyambirira wakumwa ndilabwinoko kuposa kupezetsa asidi wa lactic m'maselo. Kuphatikiza apo, kuthekera uku kumalola kuti nsomba zizikhala motetezeka m'malo otere, momwe ngakhale adani omwe akufuna kupindula ndi carp crucian sakonda kusambira.
