Salt Lake Artemia Cysts rau Shrimp Larvae

Artemia yog cov kab mob ntsev-tiv taus nrog kev faib thoob ntiaj teb thiab tau siv dav hauv kev lag luam aquaculture thiab ntsev ntau lawm.

Vim muaj ntau haiv neeg nyob qhov twg lawv nyob, txawv ecological ib puag ncig, physicochemical ntsuas nyob rau hauv dej, thiab huab cua tej yam kev mob yuav ua rau muaj kev sib txawv nyob rau hauv lub lom yam ntxwv ntawm txawv hom ntawm Artemia. Cov kev sib txawv no txiav txim siab qhov zoo ntawm cov qe ntawm cov kab Artemia sib txawv. Tuam Tshoj yog nplua nuj nyob rau hauv dej ntsev pas dej Artemia, uas tau maj mam tsim thiab siv.
 

 

Txawm li cas los xij, muaj ob peb yam kev tshawb fawb. Raws li kev tshawb nrhiav dav dav, daim ntawv no xaiv cov kab mob uas muaj peev txheej loj dua lossis cov neeg sawv cev los ntawm ntau hom Artemia los txheeb xyuas cov yam ntxwv ntawm Artemia hom, tshwj xeeb tshaj yog cov qe Artemia zoo, txhawm rau ua haujlwm rau kev txhim kho thiab kev siv ntawm Tuam Tshoj lub pas dej ntsev. Artemia cov ntaub ntawv.

Peb lub tuam txhab txhawb txoj kev sau qoob loo kom raug thiab siv cov txheej txheem kev tshawb fawb, xws li kev sau qoob loo kom sai li sai tau, txo cov dej noo thaum lub sij hawm cia, tswj qhov kub thiab txias thaum lub sij hawm cia thiab ua, txo lub sij hawm ntawm kev kho dej tshiab, thiab lwm yam Meanwhile, peb kuj xav tau. txhawm rau ntxiv dag zog rau txoj hauv kev txhawm rau txhawm rau dormancy ntawm Artemia qe.

 

Cov protein
Artemia cysts muaj cov protein ntau, nrog rau cov ntsiab lus feem ntau yog li ntawm 50% mus rau 60%. Cov proteins no muaj ntau yam tseem ceeb amino acids, xws li lysine, methionine, thiab tryptophan. Qhov tseem ceeb amino acids yog cov uas cov larvae ntawm ntses, cws thiab roob ris tsis tuaj yeem ua ke ntawm lawv tus kheej los yog cov nyiaj synthesized tsis txaus kom tau raws li kev loj hlob thiab yuav tsum tau txais los ntawm cov khoom noj. Cov proteins hauv Artemia cysts, nrog rau lawv cov amino acid muaj pes tsawg leeg thiab bioavailability, muab cov khoom siv tseem ceeb rau kev tsim cov ntaub so ntswg, enzyme thiab cov tshuaj hormones synthesis ntawm cov ntses, cw thiab roob ris. Piv txwv li, thaum lub sij hawm txoj kev loj hlob ntawm cw larvae, txoj kev loj hlob sai ntawm cov nqaij ntshiv nqaij yuav tsum tau ib tug loj npaum li cas ntawm cov proteins los ua ke cov txheej txheem tseem ceeb xws li actin thiab myosin. Cov proteins hauv Artemia cysts tuaj yeem ua tau raws li qhov yuav tsum tau ua, txhawb kev loj hlob ntawm cw larvae cov leeg thiab kev tsim kho morphological ntawm lawv lub cev.

 

Cov rog
Cov rog kuj suav nrog feem ntau ntawm cov kab mob Artemia, kwv yees li 15% txog 20%. Lawv yog cov nplua nuj nyob rau hauv unsaturated fatty acids, xws li linoleic acid, linolenic acid, thiab docosahexaenoic acid (DHA). Unsaturated fatty acids ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub paj hlwb, kev tsim kho qhov muag, thiab kev saib xyuas cov qauv thiab kev ua haujlwm ntawm cov cell membranes ntawm cov larvae ntawm ntses, cw thiab roob ris. Raws li ib qho tseem ceeb ntev-chain polyunsaturated fatty acid, DHA plays lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm retina thiab lub hlwb ntawm cov ntses larvae. Kev tshawb fawb qhia tau hais tias nyob rau hauv tus txheej txheem ntawm salmon seedling yug me nyuam, pub Artemia cysts nplua nuj nyob rau hauv DHA tuaj yeem txhim kho qhov pom kev zoo thiab kev kawm muaj peev xwm ntawm cov menyuam yaus ntses, ua rau lawv ua tau zoo dua hauv kev tua tsiaj thiab evading predators. Lub caij no, cov rog kuj ua haujlwm zoo li lub zog cia khoom. Raws li qhov xwm txheej ntawm cov zaub mov tsis tshua muaj rau cov larvae lossis ib puag ncig kev ntxhov siab, lawv tuaj yeem muab kev txhawb zog txuas ntxiv rau cov larvae kom tswj tau lawv cov haujlwm hauv lub neej.

Cov vitamins
Artemia cysts muaj ntau yam vitamins, suav nrog vitamin A, vitamin D, vitamin E, vitamin K, thiab B vitamins (xws li thiamine, riboflavin, nicotinic acid, pantothenic acid, pyridoxine, biotin, folic acid, thiab cobalamin). Cov vitamins ua lub luag haujlwm ntawm coenzymes lossis pab pawg prosthetic hauv cov txheej txheem metabolic ntawm cov ntses, cws thiab roob ris, koom nrog ntau lub cev thiab cov tshuaj biochemical. Piv txwv li, vitamin A yog qhov tseem ceeb heev rau kev tsim kho qhov muag, kev saib xyuas kev ncaj ncees ntawm cov ntaub so ntswg epithelial, thiab kev tswj hwm kev tiv thaiv kab mob ntawm cov larvae; vitamin D yog pab rau calcium thiab phosphorus metabolism thiab pob txha loj hlob; vitamin E yog ib qho tseem ceeb antioxidant uas tuaj yeem tiv thaiv lub hlwb ntawm cov larvae los ntawm kev puas tsuaj los ntawm cov dawb radicals thiab txhim kho lawv cov kev ntxhov siab; Cov vitamins B muaj kev koom tes hauv cov metabolism ntawm carbohydrates, cov rog thiab cov protein, ua kom lub cev ua haujlwm ntawm lub zog metabolism ntawm larvae. Nyob rau hauv tus txheej txheem ntawm crab seedling yug me nyuam, ib tug txaus mov ntawm cov vitamins yuav txhawb lub hardening ntawm lub tshiab plhaub thiab rov qab los ntawm lub cev ntawm cov me nyuam mos liab crabs tom qab molting, txo txoj kev pheej hmoo ntawm kev tuag thaum lub sij hawm molting txheej txheem.

Cov ntxhia
Artemia cysts yog nplua nuj nyob rau hauv ntau yam minerals, xws li calcium, phosphorus, sodium, potassium, magnesium, hlau, zinc, manganese, tooj liab, thiab selenium. Cov pob zeb hauv av no ua si ntau lub luag haujlwm hauv kev ua haujlwm ntawm lub cev ntawm cov larvae ntawm ntses, cws thiab roob ris. Calcium thiab phosphorus yog cov khoom tseem ceeb ntawm cov pob txha thiab carapaces, uas yog qhov tseem ceeb rau kev txhim kho pob txha thiab tsim carapace ntawm larvae. Thaum lub sij hawm tus txheej txheem ntawm cws thiab crab seedling yug me nyuam, larvae yuav tsum tsis tu ncua nqus calcium thiab phosphorus los tsim thiab ntxiv dag zog rau lawv lub plhaub. Qhov sib piv ntawm calcium-phosphorus hauv Artemia cysts yog qhov tsim nyog, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua. Cov ntsiab lus xws li sodium thiab potassium yog koom nrog hauv kev tswj hwm osmotic siab tshuav thiab acid-base tshuav nyiaj li cas ntawm cov larvae, ua kom muaj kev ruaj ntseg ntawm cov kab mob hauv lub cev thiab cov kab mob extracellular. Cov kab mob xws li hlau, zinc, manganese, tooj liab yog siv los ua cov khoom siv lossis cov activators ntawm cov enzymes, koom nrog cov txheej txheem physiological xws li kev ua pa, kev zom zaub mov, thiab kev tiv thaiv kab mob ntawm cov larvae. Piv txwv li, hlau yog ib qho tseem ceeb ntawm hemoglobin, koom nrog hauv kev thauj mus los ntawm oxygen; zinc koom nrog kev tswj hwm ntawm kev ua haujlwm ntawm ntau yam enzymes, muaj kev cuam tshuam tseem ceeb rau kev loj hlob thiab kev loj hlob thiab kev tiv thaiv kab mob ntawm cov larvae.
