Ukusabela okuhlukahlukene kokucindezeleka kuthinta kakhulu ukuphakelwa nokukhula kwezilwane zasemanzini, kunciphisa izinga lokusinda, futhi kubangele nokufa. Ukwengezwa kwe-betaine ekudleni kungasiza ekuthuthukiseni ukwehla kokudla kwezilwane zasemanzini ngaphansi kwezifo noma ingcindezi, ukugcina ukudla okunomsoco futhi kunciphise izimo ezithile zezifo noma ukusabela kokucindezeleka.

I-Betaine ingasiza i-salmon ukumelana nengcindezi ebandayo engaphansi kuka-10 ℃, futhi iyisengezo sokuphakelayo esifanelekile kwezinye izinhlanzi ebusika. Izithombo ze-carp zotshani ezithuthwa ibanga elide zafakwa emachibini A no-B anezimo ezifanayo ngokulandelana. I-0.3% ye-betaine yengezwe ekudleni kwe-carp yotshani echibini a, futhi i-betaine ayizange yengezwe ekudleni kwe-carp yotshani echibini B. Imiphumela yabonisa ukuthi izithombo ze-carp zotshani echibini zazisebenza emanzini, zidla ngokushesha, futhi azifanga; Ukuthosa echibini B kudle kancane futhi ukufa kwaba ngu-4.5%, okubonisa ukuthi i-betaine inomphumela wokulwa nokucindezeleka.

I-Betaine iyisivikeli sento yokucindezeleka kwe-osmotic. Ingasetshenziswa njenge-ejenti yokuvikela i-osmotic yamaseli. Ingakwazi ukuthuthukisa ukubekezelelana kwamangqamuzana e-biological esomiso, umswakama ophezulu, usawoti ophezulu kanye nemvelo ye-hypertonic, ivimbele ukulahlekelwa kwamanzi e-cell kanye nokungena kukasawoti, ithuthukise umsebenzi wepompo ye-Na-K ye-cell membrane, iqinise umsebenzi we-enzyme kanye nomsebenzi we-biological macromolecular, ukuze ulawule izicubu kanye ne-cell osmotic ingcindezi kanye nebhalansi ye-ion, Gcina izakhi zofuzo lapho izinhlanzi zishintsha, zithuthukise ukumuncwa kwezinhlanzi, zithuthukise ukumuncwa kwezinhlanzi, futhi zithuthukise ukumuncwa okubukhali kwezinhlanzi. thuthukisa izinga lokukhuluma.

Ukugcwala kosawoti wezinto ezingaphili emanzini olwandle kuphezulu kakhulu, okungakukhuthazi ukukhula nokuphila kwezinhlanzi. Ukuhlolwa kwe-carp kubonisa ukuthi ukwengeza i-1.5% ye-betaine / i-amino acid ku-bait kunganciphisa amanzi emisipha yezinhlanzi zasemanzini ahlanzekile futhi kubambezele ukuguga kwezinhlanzi zasemanzini ahlanzekile. Uma ukugcwala kukasawoti wezinto eziphilayo emanzini kukhuphuka (njengamanzi olwandle), kuyasiza ukugcina ibhalansi ye-electrolyte ne-osmotic pressure yezinhlanzi zasemanzini ahlanzekile futhi wenze uguquko lusuka ezinhlanzini zasemanzini ahlanzekile luye endaweni yamanzi olwandle ngokushelela. I-Betaine isiza izidalwa zasolwandle ukuthi zigcine usawoti omningi emizimbeni yazo, zigcwalise amanzi ngokuqhubekayo, zibambe iqhaza ekulawuleni i-osmotic, futhi zenze izinhlanzi zasemanzini ahlanzekile zikwazi ukuzivumelanisa nokushintsha kwendawo yamanzi olwandle.
