Ukusabela okuhlukahlukene kokucindezeleka kuthinta kakhulu ukondliwa nokukhula kwezilwane zasemanzini, kunciphisa izinga lokusinda, futhi kubangele nokufa.i-betaineUkudla okuphakelayo kungasiza ekuthuthukiseni ukwehla kokudla kwezilwane zasemanzini ngenxa yesifo noma ukucindezeleka, ukugcina ukudla okunomsoco futhi kunciphise ezinye izimo zesifo noma ukusabela kokucindezeleka.

I-Betaineingasiza i-salmon ukumelana nokucindezeleka okubandayo ngaphansi kuka-10 ℃, futhi iyisengezo sokudla esifanele sezinhlanzi ezithile ebusika. Izithombo ze-carp zotshani ezithuthwa ibanga elide zafakwa emachibini A no-B ngezimo ezifanayo ngokulandelana. I-0.3% ye-betaine yengezwe ekudleni kwe-carp yotshani echibini A, kanti i-betaine ayizange yengezwe ekudleni kwe-carp yotshani echibini B. Imiphumela ikhombisile ukuthi izithombo ze-carp zotshani echibini A zazisebenza emanzini, zidla ngokushesha, futhi azifanga; Ama-fry echibini B adla kancane kanti ukufa kwaba ngu-4.5%, okubonisa ukuthi i-betaine inomphumela wokulwa nokucindezeleka.

I-Betaineiyisithako esivikela ukucindezeleka kwe-osmotic. Ingasetshenziswa njengesivikelo se-osmotic samaseli. Ingathuthukisa ukubekezelelana kwamaseli ezinto eziphilayo nesomiso, umswakama ophezulu, usawoti omningi kanye nendawo ezungezile ene-hypertonic, ivimbele ukulahleka kwamanzi esisele kanye nokungena kukasawoti, ithuthukise ukusebenza kwephampu ye-Na-K ye-membrane yesisele, izinzise umsebenzi we-enzyme kanye nomsebenzi we-macromolecular wezinto eziphilayo, ukuze ilawule ingcindezi yezicubu kanye ne-cell osmotic kanye nebhalansi ye-ion, igcine umsebenzi wokumuncwa kwezakhamzimba, ithuthukise ukubekezelelana kwezinhlanzi kanye ne-shrimp lapho ingcindezi ye-osmotic ishintsha kakhulu, futhi ithuthukise izinga lokukhuluma.

Ukuhlushwa kukasawoti ongaphili emanzini olwandle kuphezulu kakhulu, okuyinto engavumeli ukukhula nokusinda kwezinhlanzi. Ukuhlolwa kwe-carp kukhombisa ukuthi ukwengeza i-1.5% ye-betaine / i-amino acid esithelweni kunganciphisa amanzi emisipheni yezinhlanzi zamanzi ahlanzekile futhi kulibazise ukuguga kwezinhlanzi zamanzi ahlanzekile. Lapho ukuhlushwa kukasawoti ongaphili emanzini kukhuphuka (njengamanzi olwandle), kusiza ukugcina ibhalansi ye-electrolyte kanye ne-osmotic pressure yezinhlanzi zamanzi ahlanzekile futhi kwenze ushintsho oluvela ezinhlanzini zamanzi ahlanzekile luye endaweni yasemanzini olwandle lube lula. I-Betaine isiza izinto eziphilayo zasolwandle ukugcina ukuhlushwa kukasawoti ophansi emizimbeni yazo, igcwalise amanzi njalo, idlala indima ekulawulweni kwe-osmotic, futhi ivumele izinhlanzi zamanzi ahlanzekile ukuthi zivumelane nokuguqulwa endaweni yasemanzini olwandle.
