Nrog rau kev nce qib ntawm kev siv thev naus laus zis, kev lag luam aquaculture kuj tseem loj hlob thiab nthuav dav.Txawm li cas los xij, hauv cov txheej txheem no, cov neeg ua liaj ua teb tau ntsib ntau yam kev cov nyom, xws li cov kab mob tsis tu ncua, dej tsis zoo, thiab cov nqi nce ntxiv.Txawm li cas los xij, hauv cov txheej txheem no, cov neeg ua liaj ua teb tau ntsib ntau yam kev nyuaj, xws li cov kab mob tsis tu ncua, dej tsis zoo, thiab cov nqi nce ntxiv. thiab cov additives tau tshwm sim. Ntawm lawv,ecdysterone, raws li ib tug natural biological active tshuaj, tau attracted thoob plaws hauv lub domestic thiab txawv teb chaws aquaculture kev lag luam.
I. Physiological teebmeem ntawm Ecdysterone
Ecdysterone yog cov tshuaj steroid nrog ntau lub cev lub cev ua haujlwm uas feem ntau ua rau cov kab mob metamorphosis thiab kev loj hlob ntawm cov kab thiab qee cov crustaceans. Cov teebmeem antioxidant, ua rau nws muaj cov ntawv thov dav dav hauv aquaculture.
II.Kev thov ntawm Ecdysterone hauv Aquaculture
Txhawb kev loj hlob thiab nce yields
Ecdysterone tuaj yeem txhawb txoj kev loj hlob ntawm cov tsiaj hauv dej thiab nce yields.Nyob rau hauv kev tshawb fawb ntawm 斑节对虾 (Penaeus monodon), pawg sim nrog ntxiv ecdysterone nce hauv kev loj hlob ntau dua 30% piv rau pawg tswj hwm (Smith li al., 2010 ). Hauv lwm txoj kev tshawb fawb ntawm Atlantic salmon (Salmo salar), ntxiv ecdysterone nce qhov hnyav nruab nrab ntawm cov ntses los ntawm 20% (Jones et al., 2012).
Txhim kho kab mob
Ecdysterone muaj cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob, thiab tshuaj tua kab mob antioxidant, uas tuaj yeem txhim kho cov kab mob tiv thaiv ntawm cov tsiaj hauv dej. Cov kev tshawb fawb tau pom tias ntxiv ecdysterone tuaj yeem txo qhov tshwm sim ntawm cov ntses kis kab mob (Johnson li al., 2013).
Txhim kho dej zoo
Ecdysteronetuaj yeem txhawb cov photosynthesis ntawm cov nroj tsuag dej thiab txhim kho cov dej zoo.Nyob rau hauv kev tshawb fawb ntawm macroalgae, ntxiv ecdysterone nce photosynthesis los ntawm 25% (Wang et al., 2011).
III.Economic Analysis
Ntxiv ecdysterone tuaj yeem txo cov nqi yug me nyuam, nce yields, thiab nyiaj txiag txiaj ntsig.Nyob rau hauv kev tshawb fawb ntawm Atlantic salmon, ntxiv ecdysterone nce qhov hnyav nruab nrab ntawm cov ntses los ntawm 20% thaum txo cov nqi noj thiab cov nqi tshuaj (Jones li al., 2012).Qhov no qhia. tias ecdysterone muaj txiaj ntsig tseem ceeb hauv kev lag luam hauv dej hiav txwv.
IV.Kev xaus lus thiab Kev Tshawb Fawb Txog Yav Tom Ntej
EcdysteroneNws muaj peev xwm txhawb kev loj hlob ntawm cov tsiaj hauv dej, nce yields thiab kab mob tiv thaiv, txhim kho dej zoo, thiab txo tus nqi yug me nyuam.Txawm li cas los xij, tseem muaj qee qhov teeb meem hauv kev tshawb fawb tam sim no ntawm daim ntawv thov ntawm ecdysterone hauv aquaculture, xws li Raws li cov qauv siv tshuaj tsis sib haum thiab tsis siv cov qauv siv.Yog li ntawd, kev tshawb fawb yav tom ntej yuav tsum tsom mus rau kev txhim kho cov kev cai siv thiab cov qauv siv tshuaj ntawm ecdysterone txhawm rau tshawb nrhiav nws cov peev txheej hauv kev ua liaj ua teb.
