Crustacean aquaculture, piv txwv li, los tsa cws, prawns, lobsters, thiab crabs, yog ib qho ntawm cov khoom lag luam thoob ntiaj teb. Raws li cov neeg siv khoom qhia ua yeeb yam zoo zuj zus ntawm kev ua tau zoo, cov khoom lag luam nqaij ntses, cov neeg tsim khoom noj kom zoo los txhim kho kev noj qab haus huv, thiab kev lag luam ntawm nws cov khoom. Khoom noj khoom haus muab lub hauv paus rau qhov kev tsim nyog no, thiab kev siv cov pub noj muaj ntxiv yog qhov tseem ceeb. Ntawm tag nrho cov txiv ntoo cov khoom xyaw ua haujlwm,Astaxanthin HmoovNiaj hnub no yog qhov ua ntej ntawm Crustacean kev ua tau zoo, pigmentation, spawning, thiab tag nrho zoo {{0}- ua. Cov blog no qhia txog qhov tseem ceeb ntawmAstaxanthin HmoovRau crustacean aquaculture, nws txoj haujlwm ua haujlwm, nws txoj kev noj qab haus huv thiab cov kev cuam tshuam thiab muaj sia nyob rau kev lag luam.
Dab tsi yog astaxanthin hmoov?
Astaxanthinyog xoom xanthophyll carotenoid xim. Nws yog ntawm cov pigments lub luag hauj lwm rau liab -}}}}}}}}}}}} txiv kab ntxwv hu ua cws, lobsters, thiab crabs, tshwj xeeb yog ib zaug siav.AstaxanthinYog nqus tau los ntawm cov crustaceans los ntawm microalgae (zoo li haematococcus pluvialis) lossis los ntawm kev siv lwm yam tsiaj muaj sia ntawm cov xim xim.
Nates cov chaw muaj tsawg tsawg hauv aquaculture, thiabAstaxanthinyog ntxiv nrog microalga hmoov, poov xab (phaffia rhaurozyma), lossis hluavtaws Astaxanthin. Ntuj Astaxanthin yog qhov tseem ceeb tshaj plaws tom qab vim nws muab lub peev xwm txaij loj dua thiab cov xyoob ntoo loj thiab yog li muaj zog tshaj nyob rau hauv kev ua induction thiab kev noj qab haus huv.
Lub luag hauj lwm ntawm Astaxanthin hauv Crustacean Biology
Astaxanthinyog tsis yog ib qho xim daj - Nws muaj cov txiaj ntsig roj ntsha muaj peev xwm ua haujlwm nrog kev noj qab haus huv tam sim no thiab ntau lawm:
Antioxidant tiv thaiv
Crustaceans yog raug oxidative kev nyuaj siab vim tias muaj kuab coj ua, hloov cov dej zoo, thiab muaj kab mob kab mob. Astaxanthin yog lub zog antioxidant uas tua dawb radicals thiab pab cov ntaub thaiv npog los ntawm oxidative kev puas tsuaj.
Pigmentation thiab kev ua lag luam tus nqi
Tshaj - pigmentation yog ib qho tseem ceeb zoo hauv aquaculture ntawm cov cw thiab lobsters. Freshness thiab zoo yog dab tsi uas cov neeg siv khoom koom nrog cov liab liab -} txiv kab ntxwv xim. Tsim nyog Astaxanthin ntseeg tau txhim kho cov xim, txhim kho cov neeg siv khoom siv tau, thiab txawm tias muaj nqi ua lag luam.
Kev tiv thaiv kab mob
Astaxanthin daws cov txheej txheem tiv thaiv kab mob, txhim kho cov kab mob tiv thaiv thiab kev txawj tuag los ntawm cov kab mob uas muaj zog nyob rau hauv aquaculture.
Kev ua me nyuam muaj me nyuam
Broodstock cov khoom noj nrog Astaxanthin khaws cov gonadal kev loj hlob, qe zoo, tag nrho cov uas yog qhov tseem ceeb rau kev metchery vam meej.
Kev ntxhov siab ntxhov siab
Tus txiv neej ncig ua ke crustaceans kev kawm txog kev tuav, ntsuas kub thiab txias thiab salinity muaj kev ntxhov siab. Astaxanthin mitigates cov nyhuv ntawm kev ntxhov siab, txhim kho kev muaj sia nyob.
Qhov Zoo ntawm Astaxanthin Hmoov hauv Crustacean Aquaculture
1. Txhim Kho Kev Loj Hlob
Nws tau raug pov thawj los ntawm kev tshawb fawb tias kev txhawb nqa ntawmAstaxanthinHauv kev noj haus cov khoom noj khoom haus txhawb noj, tus nqi loj hlob, thiab pub hloov dua siab tshiab. Qhov no yog vim tias nws tuaj yeem txo qis oxidative kev ntxhov siab thiab txhim kho siv cov as-ham.
Nyob rau hauv cursp kab lis kev cai, kev coj ncaj qha hauv kev loj hlob tus nqi thiab kev ciaj sia tau ncaj qha txhais kom tau nce qoob loo thiab cov nyiaj tau los.
2. Txhim kho cov xim thiab kev ua lag luam kev lag luam
Xim yog tus yam ntxwv tseem ceeb ntawm cws thiab cov aobeter aquaculture. Crustaceans yuav whiten thiab ua tsis muaj nqis ntawm kev ua lag luam nrog qhov tsis muaj peev xwm ntawm Astaxanthin.
- Shrimp: Cov xim liab siav yog qhov ntxim nyiam tshaj plaws hauv kev lag luam thoob ntiaj teb.
- Lobsters thiab crabs: plhaub sib sib zog nqus kob tau nce cov neeg tau txais txiaj ntsig.
Los ntawm kev sib txuam Astaxanthin Hmoov, cov tuam ntxhab muaj peev xwm muab cov xim zoo, khaus, uas tau txais rau cov neeg siv khoom.
3. Txhim kho kev tiv thaiv kab mob thiab cov kab mob tsis kam
Cov kab mob epidemics nyob ib qho ntawm kev hem thawj loj tshaj plaws rau crustacean aquaculture. Astaxanthin pib ua kev lom zem thiab kev tiv thaiv kab mob ntawm tes, uas boosts cov crustaceans 'tiv taus cov kab mob thiab tus kab mob kis.
Nws tseem suppresses kev tiv thaiv kev tiv thaiv kab mob tshwm sim los ntawm oxidative kev ntxhov siab nthuav dav hauv kev sib luag.
4. Kev tsim kho kev noj qab haus huv thiab cov kab muaj sia nyob
Astaxanthin tau txhim kho kev ua tub rov ua dua tshiab los ntawm kev txhim kho qe, hatnability, thiab txoj hnyuv huv. Astaxanthin Broodstock Ntxiv ua rau ib qho kev ua kom muaj kev vam meej thaum lub sijhawm muaj kev vam meej ntau ntxiv rau lub chaw loj hlob thaum ntxov.
5. Kev ntxhov siab tsis kam nyob rau hauv Aquaculture ib puag ncig
Tuav, thauj khoom ntom ntom ntom, thiab dej parameter hloov yog cov areaculture kev ntxhov siab. Cov kev txom nyem ua tsis muaj kev ntxhov siab oxidative, txo qis muaj sia nyob, thiab ua rau cov neeg raug mob ntau dua. Kev pab ntxiv Astaxanthin ntxiv ua kom muaj kev nce siab ntxiv, ua rau cov txiv ntoo muaj peev xwm muaj peev xwm ntau yam nrog nrog thaj av ua liaj ua teb.
6. Kev lag luam muaj txiaj ntsig rau cov neeg ua liaj ua teb
Astaxanthin tsis yog ua kom muaj kev noj qab haus huv ntawm cov neeg muaj kev noj qab haus huv tab sis kuj muab cov khoom tsim kho tau zoo thiab siab {{}} cov khoom tsim zoo. Nrog kev txhim kho cov xim, kev loj hlob, muaj sia nyob, thiab kev ua me nyuam txaus siab thiab kev sib tw nyob rau hauv kev sib tw dej hiav txwv.
Ntuj vs. hluavtaws Astaxanthin hauv Aquaculture
- Lub ntujAstaxanthin: Ntau tshaj li cov antioxidant thiab ntau dua bioavailable los ntawm haematococcus pluvialis microalgae lossis phaffia Rhodozyma poov xab. Kev nrhiav neeg coob ntxiv tom qab hauv cov khw uas cov neeg muas zaub nyiam natural, qhov chaw rov ua dua tshiab ntxiv thiab.
- Hluavtaws Astaxanthin: Ntau dua muaj nyob thoob ntiaj teb thiab feem ntau pheej yig dua, tab sis tsis tshua muaj zog hauv antioxidant kev ua si dua li cov khoom ntuj.
Natural astaxanthin powder is increasingly being used in high-end aquaculture production-particularly in export markets.
Astaxanthin Hmoov Siv nyob rau hauv Crustacean cov pluas noj
- Cws kab lis kev cai: koom ua ke rau hauv kev pub khoom pub pub pub pub rau ntawm cov qib feem ntau 50-150 mg / kg, nyob ntawm cov hom phiaj ntau lawm.
- Cov kab lis kev cai thiab pob kab lis kev cai: siv los tsim cov xim rau lub plhaub thiab txhim kho broodstock fertility.
- Hauncheries: koom rau hauv Broodstock kev noj haus kom txhim kho qe ua kom zoo, muaj sia nyob thiab kev loj hlob thaum ntxov.
Ntxiv yuav tsum muaj qhov txaus, nyob rau hauv {{{{{}}}}}}}}}} Supplement tshwm sim nyob rau hauv tsis tshua muaj nuj nqis heev yam tsis kim heev yam tsis tau txais txiaj ntsig zoo dua.
Kev ruaj khov thiab cov neeg siv khoom sib luag
Niaj hnub no cov neeg saib dej hiav txwv ib puag ncig yog ib puag ncig thiab kev noj qab haus huv - tsom. Lub ntujAstaxanthinNtxiv rau kev ua teb rau cov ncauj ke no:
- Kev Nyob Zoo: Microalgae -} derated NtujAstaxanthinyog txuas txuas ntxiv thiab ib puag ncig phooj ywg tus txiv neej - ua tau sib npaug.
- Khoom Noj Khoom Haus Nyab Xeeb: nqaij ntses nyoo tau tsa rau ntuj, tsis - cua phytthetic Pub yog cov neeg siv khoom xaiv yog ib qho kev xaiv cov neeg siv khoom yog cov neeg siv khoom xaiv yog ib qho kev xaiv cov neeg siv khoom yog ib qho kev xaiv cov neeg siv khoom yog cov neeg siv khoom.
- Hwm cov lag luam: xim liab, ib txwm muaj xim lobsters thiab cit dimp command hwm tus nqi hauv high {}} tus nqi export cartelts.
Los ntawm kev sib xyaw ua ke astaxanthin rau hauv pub, aquaculture cov neeg ua liaj ua teb kev ua tau zoo thiab txaus siab hauv ntiaj teb kev lag luam yuav tsum muaj cov nqaij nruab deg, kom muaj cov nqaij nruab deg.
Kev ua pov thawj scientific rau Astaxanthin hauv cov crustaceans
Cov kev tshawb fawb hauv qab no nthuav qhia qhov tseem ceeb ntawmAstaxanthinHauv dej aquaculture crustaceans:
- Chien & Shiau (2005) txiav txim siab tias Astaxanthin nyob rau hauv pub noj ntau ntxiv txhim kho kev loj hlob kev ua tau zoo, thiab cov muaj sia nyob ntawm Litpenaeus Vannamei (Pacific Dawb CARNAMEI (Pacific Dawb cws).
- Niu li al. (2009) cov lus hais tias astaxantthin pab txhawb nqa cov kev ntxhov siab thiab ua tim khawv, ua tim khawv rau kev ua haujlwm ntawm antioxidant thiab xim.
- Wade li al. (2017) qhia tias Astaxanthin txhim kho BroodstockPility Sporility uas zoo li Larval Vojility hauv crustaceans, bearing tim zog rau nws lub peev xwm yuav muaj peev xwm.
