I-Ecdysterone: Ukuphumelela Okusha Embonini Yezasemanzini

Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, imboni yezokulima emanzini nayo iyakhula futhi yanda.Nokho, kule nqubo, abalimi babhekene nezinselele eziningi, njengezifo ezivamile, ukuwohloka kwezinga lamanzi, kanye nezindleko ezikhulayo.Ukuxazulula lezi zinkinga, izindlela eziningi zokuzalanisa ezintsha. kanye nezithasiselo ziye zavela.Phakathi kwazo,i-ecdysterone,njengento yemvelo esebenzayo yebhayoloji, idonse ukunaka okusabalele embonini yezasemanzini yasekhaya neyangaphandle.

I.Imiphumela Yokuphila Kwe-Ecdysterone

I-Ecdysterone iyisithako esine-steroid esinemisebenzi eminingi yomzimba esebenza ngokuyinhloko ekuguquguqukeni nasekukhuleni kwezinambuzane kanye namanye ama-crustaceans.Ingakhuthaza i-larval molt, isheshise ukukhula, futhi ithuthukise amazinga okusinda. imiphumela ye-antioxidant, iyenza ibe namathemba abanzi wokusetshenziswa kwezilwane zasemanzini.

II.Ukusetshenziswa kwe-Ecdysterone ku-Aquaculture

Ukukhuthaza Ukukhula kanye Nokwandisa Isivuno

I-Ecdysterone ingakhuthaza kakhulu ukukhula kwezilwane zasemanzini futhi yandise isivuno.Ocwaningweni lwe-斑节对虾(Penaeus monodon),iqembu lokuhlola eline-ecdysterone eyengeziwe lenyuke ngokukhula ngamaphesenti angaphezu kuka-30 uma kuqhathaniswa neqembu lokulawula(Smith et al.,2010) ).Kolunye ucwaningo lwe-salmon yase-Atlantic(Salmo salar),ukwengeza i-ecdysterone kwenyusa isisindo esimaphakathi sezinhlanzi ngo-20%(Jones et al.,2012).

Ukuthuthukisa Ukumelana Nezifo

I-Ecdysterone ine-antibacterial, anti-inflammatory, kanye ne-antioxidant effect, engathuthukisa ukumelana nezifo ezilwaneni zasemanzini.Ucwaningo lubonise ukuthi ukwengeza i-ecdysterone kunganciphisa kakhulu amathuba okuba izinhlanzi zingenwe izifo(Johnson et al.,2013).

Ukuthuthukisa Ikhwalithi Yamanzi

I-Ecdysteroneingakhuthaza i-photosynthesis yezitshalo zasemanzini futhi ithuthukise ikhwalithi yamanzi.Ocwaningweni lwama-macroalgae, ukwengeza i-ecdysterone yanda i-photosynthesis ngo-25% (Wang et al., 2011).

III.Ukuhlaziya Umnotho

Ukwengeza i-ecdysterone kunganciphisa izindleko zokuzalanisa, kukhuphule isivuno, kanye nezinzuzo zezomnotho.Ocwaningweni lwe-salmon yase-Atlantic, ukungeza i-ecdysterone kwenyusa isisindo esimaphakathi sezinhlanzi ngo-20% kuyilapho kunciphisa izindleko zokudla kanye nezindleko zemithi(Jones et al.,2012).Lokhu kubonisa ukuthi ukuthi i-ecdysterone inezinzuzo ezibalulekile zezomnotho ekufuyelweni kwezilwane zasemanzini.

IV.Isiphetho kanye Nesiqondiso Socwaningo Lwesikhathi esizayo

I-Ecdysteroneinamathemba abanzi wokusebenzisa i-aquaculture.Ingakhuthaza ukukhula kwezilwane zasemanzini, yandise isivuno kanye nokumelana nezifo, ithuthukise izinga lamanzi, futhi yehlise nezindleko zokuzalanisa.Nokho, kusenezinkinga ezithile ocwaningweni lwamanje lokusetshenziswa kwe-ecdysterone kwezasemanzini,ezinjalo. njengamazinga okudosa angaguquki kanye nezindlela zokusetshenziswa ezingajwayelekile.Ngakho-ke, ucwaningo lwesikhathi esizayo kufanele lugxile ekuthuthukiseni imithethonqubo yokusetshenziswa kanye namazinga omthamo we-ecdysterone ukuze kuqhutshekwe kubhekwe ukubaluleka kwayo kokusetshenziswa kwezilwane zasemanzini.
