Kuita kwakasiyana-siyana kwekushushikana kunokanganisa zvakanyanya kudya nekukura kwemhuka dzemumvura, kuderedza huwandu hwekupona, uye kutokonzera rufu. Kuwedzerwa kwebetaine muchikafu kunogona kubatsira kuvandudza kudzikira kwekudya kwemhuka dzemumvura pasi pechirwere kana kushushikana, kuchengetedza kudya kunovaka muviri uye kuderedza mamwe mamiriro echirwere kana kusagadzikana.

Betaine inogona kubatsira salmon kudzivirira kutonhora kuri pasi pe10 ℃, uye inodiwa yekuwedzera chikafu kune dzimwe hove munguva yechando. Mbeu dzehuswa dzecarp dzakatakurwa kureba dzakaiswa mumadziva A neB nemamiriro akafanana. 0.3% betaine yakawedzerwa kune uswa hwecarp chikafu mudziva a, uye betaine haina kuwedzerwa kune uswa carp chikafu mugomba B. Migumisiro yakaratidza kuti uswa carp mbesa mudziva a yaishanda mumvura, yakadya nokukurumidza, uye haina kufa; Fry mudziva B yaidya zvishoma nezvishoma uye kufa kwaive 4.5%, zvichiratidza kuti betaine ine anti stress effect.

Betaine chinhu chinodzivirira kune osmotic stress. Inogona kushandiswa se osmotic inodzivirira mumiriri wemasero. Inogona kuvandudza kushivirira kwemasero ezvisikwa kusvika pakusanaya kwemvura, kunyorova kwakanyanya, munyu wakawanda uye hypertonic nharaunda, kudzivirira kurasikirwa kwesero mvura uye kupinda mumunyu, kuvandudza basa reNa-K pombi ye cell membrane, kudzikamisa enzyme basa uye biological macromolecular basa, kuitira kutonga matishu uye cell osmotic kumanikidza uye ion chiyero, Chengetedza zvinovaka muviri kunyura kwehove, kusimudzira kunyura kwehove uye kusimba kwehove. kunatsiridza mwero wekutaura.

Kuwanda kwemunyu mumvura yegungwa kwakakwira zvakanyanya, izvo zvisingakodzeri kukura uye kurarama kwehove. Kuedza kwecarp kunoratidza kuti kuwedzera 1.5% betaine / amino acid kune chirauro kunogona kuderedza mvura mumhasuru yehove dzemvura yakachena uye kunonoka kuchembera kwehove dzemvura yakachena. Kana huwandu hwemunyu mumvura huchiwedzera (semvura yegungwa), zvinobatsira kuchengetedza electrolyte uye osmotic pressure balance yehove dzemvura yakachena uye kuita shanduko kubva kuhove dzemvura yakachena kuenda kunharaunda yemvura yegungwa zvakanaka. Betaine inobatsira zvipenyu zvemugungwa kuchengetedza munyu wakaderera mumiviri yavo, ichiramba ichizadza mvura, ichiita basa mukutonga kweosmotic, uye kugonesa hove dzemvura yakachena kuti dzienderane neshanduko kunharaunda yemvura yegungwa.
