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 yokubanda engaphansi kuka-10 ℃, futhi iyisengezo sokuphakelayo esifanelekile kwezinye izinhlanzi ebusika.Izithombo zotshani ze-carp 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 a zazisebenza emanzini, zadla ngokushesha, futhi zadla. ungafi;Ukuthosa echibini B kudle kancane futhi ukufa kwaba ngu-4.5%, okubonisa ukuthi i-betaine inomphumela wokulwa nokucindezeleka.

I-Betaine iyinto eyisivikelo yengcindezi ye-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 eseli kanye nokungena kukasawoti, ithuthukise umsebenzi wepompo ye-Na-K ye-cell membrane, iqinise umsebenzi we-enzyme kanye nomsebenzi we-biological macromolecular, ukuze ukulawula izicubu kanye ne-cell osmotic pressure kanye nebhalansi ye-ion, Gcina umsebenzi wokumuncwa izakhi, uthuthukise ukubekezelelana kwezinhlanzi nezimfanzi lapho ingcindezi ye-osmotic ishintsha kakhulu, futhi ithuthukise 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.
