Cov Lus Qhia thiab Cov Lus Qhia
Khaws Cia Brine Cw Qe:
Brine cws qeyuav tsum muab ceev cia raws li hauv qab no:
pub dawb los ntawm ya raws; andin ib puag ncig txias ntawm lossis qis dua 10 ° C.
Hatching ib puag ncig - Ua raws cov lus qhia no rau qhov zoo tshaj plaws:
Salinity:
Kwv yees li 11 / 2tables cov ntsev ib quart (lossis litre) ntawm cov dej. Qhov no tsis sib thooj rau txog 1.018 kev nqus tshwj xeeb raws li ntsuas nrog ahydrometer. Thoob dej yug ntses, hiav txwv lossis tsis-iodized rooj ntsev yuav siv tau.
pH:
PH kom zoo yog ib qho tseem ceeb hauv daug cov cw ntses brine. Kev pib pH ntawm 8.0 lossis siab dua yog qhov pom zoo. Yog tias tus pH ntawm koj cov dej nyob hauv qab 7, Epson ntsev los yog ci dej qab zib tuaj yeem muab ntxiv rau ntawm tus nqi ntawm 1 / 2te ស្លាបព្រា ib quart.
Kub:
Kev xaiv kub tshaj plaws rau 24-teev tiav daug yog 26-28 ° C. Lub ntsuas kub yuav ua rau lub sijhawm rub ntev ntev, tab sis tsis tshaj 30 ° C.
Teeb:
Qhov ua kom pom kev ntxiv tau ntxiv kom tau txais qhov zoo tshaj plaws daug lawm, puag ncig 2000lux.
Aeration:
Kev pib sib zog tas li yog qhov tsim nyog txhawm rau txhawm rau txhawm rau tshem tawm thiab muab cov pa oxygen txaus rau qhov hlwv daug. Ib qho dej ntws zoo ntawm lub aeration uas tumbles lub qe tsis thawb lawv saum cov dej saum npoo thiab mus rau sab ntawm lub duav daug.
Ceev cov vuam txwv:

Txaj-hauv qab nqaj yuav tsum zam. Cone lossis" V" Cov thawv hauv qab yog qhov zoo tshaj plaws kom paub tseeb tias cov hlwv nyob twj ywm rau hauv kev ncua thaum rub tawm. Nco ntsoov ntxuav kom huv lub duav nrog lub teeb tshuaj tov tshuaj, yaug, thiab tso cua kom qhuav ntawm kev siv.
Txheej txheem Hatching
Cov kauj ruam hauv qab no yuav ua tiav zoo tshajbrine cws qedaug tus nqi.
Teeb:
Qhov chaw daug daug los sis lub nkoj zoo sib xws nyob ntawm thaj chaw muaj teeb pom kev zoo. Lub khob hliav qab yuav tsum yog semi-translucent rau kev yooj yim ntawm kev sau thiab lub teeb kis tau.
Ntxiv dej:
Sau lub khob hliav qab nrog ib liter dej thiab ntxiv 1/2 diav ntsev. Qhov zoo tshaj plaws rub tawm kub yog 82 ° F (28 ° C).
Ntxiv Cysts:
Ntxiv cov hlwv rau ntawm tus nqi ntawm 1 gram rau ib liter lossis quart lossis kwv yees li 1/2 qib me nyuam diav ntawm cov hlwv rau ib quart yog qhov kev pom zoo. Ib qho peev txheej siab dua yuav ua rau qhov qis qis qis dua.
Tshaj tawm:
Ua kom muaj kev tsim nyog txaus los ua kom cov cyst hauv kev ncua.
Hatch:
Ua raws li qhov dej kub, qhov nti yuav tsum tawm li ntawm 18-36 teev.
Sau:
Tom qab daug cov brine cws, tig tawm lossis tshem tawm aeration thiab tos ob peb feeb rau cov plhaub thiab thiab tus menyuam brine cws (lossis nauplii) cais. Nauplii tshiab khiv yuav nyob rau hauv qab ntawm lub khob hliav qab los yog txav ntawm lub teeb ci; cov mos txwv yuav ntab mus rau saum npoo. Cov qe muaj qe yog xim av thiab tus menyuam brine cws yog cov txiv kab ntxwv ntau dua. Ib zaug sib cais, cov nauplii tuaj yeem siphoned los ntawm hauv qab nrog qhov ntev ntawm cov cua tubing los yog maj mam muab zaws kom qis mus rau hauv qab ntawm lub khob hliav los ntawm ib lub valve, yog tias muaj.
Yaug:
Qhov sov sov tawm kom sov thiab muab cov khoom sib xyaw los ntawm lub daug nruab nrab tsim qhov zoo tagnrho rau cov kab mob tawg. Kev yaug tus menyuam cov ntses cij hauv lub tawb zoo nkauj lossis sieve siv dej ntshiab lossis ntsev yog qhov tseem ceeb ua ntej pub rau koj cov ntses.
Khoom Siv Huv:
Cov pas tso tsheb hlau luam thiab brine cws cov cuab yeej tawm yuav tsum tau muab ntxuav thiab ntxuav kab mob tas li.
Cov txheej txheem rau Artemia yog dab tsiCyts?
Ntsev: 20-30 seem ib txhiab (ppt) tov ntsev los yog kwv yees li 1-2 dia pob zeb ntsev rau ib quart (lossis litre) dej. Qhov no sib npaug rau ib puag ncig 1.015-1.020 lub ntiajteb txawj nqus. Ib 20% (lossis ib ncig ntawm 1/2 diav ib quart) concentration ntawm Epson ntsev lossis magnesium sulfate tuaj yeem raug ntxiv rau qhov tsis haum ntxiv ntawm cov tshuaj daug lawm.
Ntsig Kub: Kev ntsuas kub kom zoo tshaj plaws hauv 24 teev tas nthuaj 26-28 ° C. Kev ntsuas kub kom tsawg yuav ua rau lub sijhawm rub ntev ntev. Tsis pub tshaj 30 ° C.
Lub Teeb: Illumination yog qhov tsim nyog los ua lub tshuab daug plaub hauv lub embryo hauv thawj ob peb teev ntawm kev tsim kom loj hlob. Saib xyuas kom muaj lub teeb pom kev zoo nyob rau lub sijhawm tag nrho tsim kom pom zoo kom tau txais qhov txiaj ntsig zoo tshaj plaws thiab ntsuas kub.
Aeration: Kev pib aeration tas li kuj tsim nyog los muab cov pa oxygen txaus rau cov hlwv rau kev zom thiab tawm hws. Qhov tsawg kawg ntawm 3 feem ntawm ib lab yaj oxygen thaum lub sijhawm tsim tawm pom zoo. Lub zog muaj zog yuav tsis ua kom puas lossis ua rau lub brine cw cysts lossis nauplii.
pH:Kev pib pH ntawm 8.0 lossis siab dua yog qhov pom zoo. Yog tias pH poob qis dua 7.5 thaum lub sijhawm ntxiv, ntxiv ib me nyuam diav sodium sodium bicarbonate lossis pH tsis ua kom nws siab dua 8.0.
Stocking Ceev:Pom zoo kom pom txog 2 gram rau ib quart lossis kwv yees li ib theem me nyuam diav ntawm cov hlwv ib quart. Ntau dua qhov khoom siv ntom ntom yuav ua rau qis qis dua% daug.
Pob Kws Tuag Tes:Ca lub hauv qab kaus duav hlab ntsha yuav tsum tau zam. Cone lossis" V" Cov thawv hauv qab yog qhov zoo tshaj plaws kom paub tseeb tias cov hlwv nyob twj ywm rau hauv kev ncua thaum rub tawm. Nco ntsoov ntxuav lub duav nrog lub xab npum thiab dej thiab kom cua qhuav ntawm kev siv.
Kuv yuav sau cov me nyuam brine cws ua li cas?
Txhawm rau sau tus menyuam brine cws los yog nauplii, tsuas yog kaw kaw huab cua thiab tos ob peb feeb rau plhaub thiab nauplii cais. Lub khauj yuav ntab mus rau saum npoo thiab cov nauplii uas muaj sia nyob yuav nkag mus rau hauv qab ntawm lub khob hliav qab rau ntawm lub teeb ci. Ib zaug sib cais, nauplii tuaj yeem siphoned los ntawm hauv qab los yog nqus dej hauv qab ntawm lub khob hliav qab los ntawm cov pa tub.
