Maikutlo a fapaneng a khatello ea maikutlo a ama ka botebo ho fepa le ho hōla ha liphoofolo tsa metsing, ho fokotsa lebelo la ho phela, esita le ho baka lefu. Ho eketsoa ha betaine lijong ho ka thusa ho ntlafatsa phokotso ea lijo tsa liphoofolo tsa metsing tlas'a lefu kapa khatello ea maikutlo, ho boloka phepo e nepahetseng le ho fokotsa maemo a mang a mafu kapa khatello ea maikutlo.

Betaine e ka thusa salmon ho hanela khatello ea maikutlo e batang e ka tlase ho 10 ℃, 'me ke motsoako o loketseng oa lijo bakeng sa litlhapi tse ling mariha. Lipeo tsa joang ba carp tse tsamaisoang sebaka se selelele li ile tsa kenngoa matangoaneng A le B a nang le maemo a tšoanang ka ho latellana. 0.3% betaine e ile ea eketsoa lijong tsa joang ba carp ka letamong la a, 'me betaine ha ea ka ea kenngoa lijong tsa joang ba carp letamong la B. Liphello li bontšitse hore lipeo tsa joang ba carp ka pond a li ne li le mafolofolo metsing, li ja kapele, 'me ha lia shoa; Fry ka letamong la B e ne e ja butle mme lefu e ne e le 4.5%, ho bonts'a hore betaine e na le phello e thibelang khatello ea maikutlo.

Betaine ke ntho e thibelang khatello ea kelello ea osmotic. E ka sebelisoa e le ntho e sireletsang osmotic bakeng sa lisele. E ka ntlafatsa mamello ea lisele tsa likokoana-hloko ho komello, mongobo o phahameng, letsoai le phahameng le tikoloho ea hypertonic, ho thibela tahlehelo ea metsi a sele le ho kena ha letsoai, ho ntlafatsa ts'ebetso ea pompo ea Na-K ea lera la sele, ho tsitsisa ts'ebetso ea enzyme le ts'ebetso ea likokoana-hloko tsa macromolecular, e le ho laola lik'hemik'hale le sele ea osmotic khatello le ion ho leka-lekana, ho boloka limatlafatsi ha li ntse li sebetsa, ho boloka limatlafatsi le ho matlafatsa ts'ebetso ea tlhapi, ho ntlafatsa ts'ebetso ea li-shrimp, ntlafatsa lebelo la puo.

Matsoai a mangata ka metsing a leoatle a phahame haholo, a sa khoneng ho hōla le ho phela ha litlhapi. Teko ea carp e bontša hore ho eketsa 1.5% betaine / amino acid ho bait ho ka fokotsa metsi ka har'a mesifa ea litlhapi tsa metsi a hloekileng le ho liehisa ho tsofala ha litlhapi tsa metsi a hloekileng. Ha letsoai le sa tsitsang metsing le eketseha (joaloka metsi a leoatle), hoa thusa ho boloka botsitso ba electrolyte le osmotic khatello ea metsi a metsi a hloekileng le ho etsa phetoho ho tloha tlhapi ea metsi a hloekileng ho ea tikolohong ea metsi a leoatle hantle. Betaine e thusa likokoana-hloko tsa metsing ho boloka letsoai le lenyenyane 'meleng ea tsona, li lula li tlatsa metsi, li bapala karolo ea taolo ea osmotic, le ho thusa litlhapi tsa metsing a hloekileng ho ikamahanya le phetoho ea tikoloho ea metsi a leoatle.
