Iindlela ezahlukeneyo zokusabela kuxinzelelo zichaphazela ngokunzulu ukondla nokukhula kwezilwanyana zasemanzini, zinciphisa izinga lokusinda, zide zibangele nokufa.Ukongezwa kwe-betaine ekutyeni kunokunceda ekuphuculeni ukwehla kokutya kwezilwanyana zasemanzini phantsi kwesifo okanye uxinzelelo, ukugcina ukutya okunomsoco kunye nokunciphisa ezinye iimeko zesifo okanye ukusabela koxinzelelo.

I-Betaine inokunceda i-salmon imelane noxinzelelo lwengqele engaphantsi kwe-10 ℃, kwaye sisongezo sesondlo esifanelekileyo kwiintlanzi ezithile ebusika.Izithole zengca zecarp ezithuthwe umgama omde zafakwa kumachibi A kunye no-B aneemeko ezifanayo ngokulandelelanayo.I-0.3% ye-betaine yongezwa kwi-carp feed yengca echibini, kwaye i-betaine ayizange ifakwe kwi-carp feed yengca echibini B. Iziphumo zabonisa ukuba izithole zengca ye-carp echibini zazisebenza emanzini, zatya ngokukhawuleza, kwaye zenza ungafi;I-Fry kwidama B itye kancinci kwaye ukufa kwaba yi-4.5%, ebonisa ukuba i-betaine ine-anti stress effect.

I-Betaine sisithinteli soxinzelelo lwe-osmotic.Ingasetyenziswa njengesixhobo sokukhusela i-osmotic kwiiseli.Inokuphucula ukunyamezela kweeseli zebhayoloji kwimbalela, umswakama ophezulu, ityuwa ephezulu kunye ne-hypertonic environment, ukukhusela ukulahleka kwamanzi eseli kunye nokungena kwetyuwa, ukuphucula umsebenzi we-Na-K pump ye-cell membrane, ukuzinzisa umsebenzi we-enzyme kunye nomsebenzi we-biological macromolecular, ukuze ukulawula izicubu kunye ne-cell osmotic pressure kunye ne-ion balance, Gcina umsebenzi wokufunxa izondlo, ukwandisa ukunyamezela kweentlanzi kunye ne-shrimp xa uxinzelelo lwe-osmotic lutshintsha ngokukhawuleza, kwaye uphucule isantya sokuthetha.

Ingxubevange yeetyuwa ze-inorganic kumanzi olwandle iphezulu kakhulu, nto leyo engabangeli ukukhula kunye nokuphila kweentlanzi.Uvavanyo lwe-carp lubonisa ukuba ukongeza i-1.5% ye-betaine / i-amino acid kwi-bait inokunciphisa amanzi kwi-muscle yentlanzi yamanzi kunye nokulibazisa ukuguga kweentlanzi zamanzi ahlambulukileyo.Xa ukuxinana kwetyuwa ye-inorganic emanzini kunyuka (njengamanzi olwandle), kuyanceda ukugcina i-electrolyte kunye ne-osmotic yoxinzelelo lwe-osmotic ibhalansi yoxinzelelo lwamanzi ahlambulukileyo kwaye wenze utshintsho olusuka kwiintlanzi zamanzi ahlaziyekileyo ukuya kwindawo yamanzi olwandle kakuhle.I-Betaine inceda izinto eziphilayo zaselwandle zigcine ityuwa ephantsi emizimbeni yazo, ngokuqhubekayo izalisa amanzi, idlala indima kulawulo lwe-osmotic, kwaye yenza ukuba iintlanzi zasemanzini ahlaziyekileyo ziqhelane noguquko kwimekobume yamanzi olwandle.
