Cov khoom noj tau ua tiav ua tsaug rau cov tshuaj ua haujlwm ntawm cov kua qaub uas tawm los ntawm cov qog qaub ncaug hauv qhov ncauj.
Txawm li cas los xij, nws qhov tseem ceeb tshaj plaws yog nws calcium carbonate plhaub, uas yog tsim los ntawm peb txheej uas tshwm sim los ntawm cov qog nqaij hlav tshwj xeeb. Hauv lub plhaub yog lub viscera. Thaum tus qwj xav tias muaj kev phom sij, nyob rau hauv qhov chaw so lossis cov xwm txheej sab nraud tsis zoo, nws thim rov qab rau hauv nws thiab kaw nrog lub npe hu ua mucous operculum, uas ua rau tawv nqaij thiab tsim cov yeeb yaj kiab uas ua rau cov qwj tiv thaiv thiab noo. Tsis tas li ntawd, kom hibernate, nws kaw lub plhaub nrog ib hom calcareous thiab ntxeem tau hau uas nws poob nrog lub sij hawm tuaj txog ntawm lub caij sov. Yog tias muaj dej nag hauv lub hlis sov, nws tuaj yeem ua rau tuag tes tuag taw lawv txoj haujlwm.
ZAUM TXHUA LUB CAIJ NTAWM LUB DIM ZAUB ME, qhov ncauj. Cov hnoos qeev ua rau txo qis kev sib txhuam, kom cov qwj tuaj yeem txav tau yooj yim hla txhua hom nto, nrog rau qhov ntxhib tshaj plaws.
Thaum kawg, lwm qhov yooj yim tshaj plaws paub cov yam ntxwv ntawm cov qwj yog nws qhov tshwj xeeb retractable ob lub qhov muag nyob rau ntawm qhov kawg ntawm ob lub tentacles ntev. Ib yam li ntawd, lub zeem muag ntawm tus tsiaj no muaj tsawg heev, yog li nws tsuas yog qhov txawv ntawm pawg thiab lub teeb.
Snails yug li cas?
Lwm tus yam ntxwv zoo ntawm cov qwj yog lawv yog hermaphroditic, uas yog, lawv tsim cov phev thiab qe, tab sis tsis ua. tus kheej fertilize, yog li lawv yuav tsum sib yuav. Lawv muaj cov kabmob sib deev uas ua rau cov xub lossis cov pob txha ntawm calcium carbonate uas nkag mus rau hauv lub cev ntawm ob niam txiv thaum sib tham los txhawb kev yug menyuam. Qhov no feem ntau tshwm sim thaum hmo ntuj. Tom qab fertilization, tus qwj nteg txog 50-60 qe nyob rau hauv ib lub qhov nws khawb hauv av, uas hatch tom qab 15 hnub. Nws tuaj yeem tso qe ib hlis ib zaug.
me kwj yuav yug tau ib lub plhaub nrog txo cov whorls. Lub plhaub loj hlob nrog cov qwj. Thaum kawg ntawm qhov kev loj hlob no yog thaum nws pib yug me nyuam. Nws qhov chaw nyob yog cov hav zoov ntshiab ntawm nplooj ntoo, cov qoob loo thiab cov av calcareous. Lawv lub neej expectancy nyob nruab nrab ntawm 2-3 xyoos.

Tsis tas li ntawd, yog tias peb tuav ntau tshaj ib qho peb yuav tuaj yeem ua pov thawj lawv cov kev sib tham thiab kev tsim tawm. Tom qab ntawd peb tuaj yeem tso lawv rau hauv ib qho chaw tsim nyog, uas yuav tsum yog lawv qhov chaw nyob hauv ntuj thiaj li tsis ua rau muaj kev puas tsuaj rau ecosystem, vim lawv tuaj yeem ua kab tsuag rau cov qoob loo. Nco ntsoov xa lawv mus rau qhov chaw koj pom lawv. Xaiv ib hnub sov thiab cia lawv nyob hauv ib qho chaw uas lawv tuaj yeem nyob. Zoo dua thaum sawv ntxov coj kom zoo dua ntawm cov av noo ntawm hmo ntuj lwg. Qhov kev saib xyuas no kuj muaj txiaj ntsig yog tias peb pom ib tus qwj nyob hauv qhov tsis zoo thiab peb xav pab kom txog thaum nws rov zoo.
Yuav ua li cas saib xyuas tus qwj?
Ntawm no peb piav qhia txog yuav ua li cas tsa qwj hauv tsev, ntawm kev saib xyuas. Koj yuav pom tias cov tsiaj no yuav tsum tau saib xyuas me ntsis, kom cov menyuam tuaj yeem saib xyuas lawv, ib txwm nyob hauv koj qhov kev saib xyuas kom lav qhov kev noj qab haus huv ntawm cov qwj.
Ua ntej, npaj lub terrarium, uas yuav yog qhov chaw uas koj snail(s) yuav nyob. Txhawm rau ua qhov no, xaiv lub thoob dej yug ntsesua los ntawm iav los yog yas, tab sis kaw thiab, ntawm chav kawm, nrog lub qhov rau oxygenation. Qee qhov kev ntsuas ntawm 30x20x20 yog tsim nyog rau ob peb snails. Thaum xaiv qhov no, khaws cov lus qhia hauv qab no:
Ideal Environment for Snails
LUB NOJ QAB Tam Sim casAV Thiab Limestone Ib puag ncig
NOJ RAU QIM Cov dej noo tuaj yeem muab nrog cov tshuaj tsuag dej ntau zaus raws li xav tau los tswj nws. Hauv qhov no, cov av noo yuav tsum tsis txhob poob qis dua 65%.
Ntawm qhov tod tes, cov av noo yuav tsum tau nrog rau qhov cua zoo kom tiv thaiv cov kab mob fungal.
Snails tsev kuj xav tau teeb pom kev zoo, tab sis tsis ncaj tshav ntuj. Lawv yuav ua haujlwm nrog qhov kub thiab txias, nyob ib ncig ntawm 20 ºC.
Pab thiab substrate rau qwj
Calcium yog qhov tsim nyog heev nyob rau hauv cov khoom noj ntawm qwj, vim nrog rau nws lawv khaws lawv cov plhaub nyob rau hauv zoo. Ib puag ncig tsis zoo thiab noj zaub mov tsis zoo tuaj yeem ua rau lub plhaub nyias nyias lossis tawg. Yog tias cov kev puas tsuaj no me me, nws tuaj yeem daws tau los ntawm kev txhim kho kev tuav. Kev raug mob hnyav lossis kev ua neej nyob tsis zoo uas tsis pub lub plhaub rov ua kom muaj kev phom sij rau cov qwj.
Ua cov calcium, lawv tuaj yeem ua kom zoo dua ntawm cov pob zeb limestone uas peb suav nrog hauv substrate. Peb tseem tuaj yeem ntxiv cov qe qe, cov pob txha cuttlefish lossis, ncaj qha, calcium blocks. Cia li cia lawv nyob rau hauv lawv qhov ncav cuag kom lawv noj tau raws li qhov xav tau thiab ntxiv rau lawv thaum lawv khiav tawm.
Tam sim no yog dab tsi zoo tagnrho substrate rau qwj? Ua ib lub substrate koj tuaj yeem siv av ntsiab cov chaw uas koj nyob, xws li av txog 6 cm kom cov qwj faus nws tus kheej thiab nteg qe., pob zeb, tshuaj ntsuab, nplooj los yog sticks. Tsis tas li ntawd, tsis txhob hnov qab muab qhov chaw nkaum!
Nyob rau cov qwj noj, cov tsiaj no noj zaub thiab txiv hmab txiv ntoo, xws li lettuce, escarole, Swiss chard, broccoli, zaub qhwv, kua, pear, txiv tsawb los yog carrot. Tshem cov seem kom sai li sai tau thaum lawv lwj thiab rov ua dua tshiab txhua hnub. Raws li qhov xav paub, peb tuaj yeem hais tias cov snails hluas nyiam nplooj, cov laus nyiam txiv hmab txiv ntoo. Yog xav paub ntxiv, tsis txhob nco lwm tsab xov xwm no: "Snails noj dab tsi?".
Thaum kawg, muab koj tus kheej ib lub qhov ntiav ntiav los tso dej rau hauv, piv txwv li, siv lub hau los ntawm ib lub hub.
Lwm txoj kev tu qaib
Txoj kev huv huv tseem ceeb heev rau kev tu cov qwj kom raug, yog li tshem tawm cov quav uas koj pom txhua hnub. Lwm yam kev ceev faj tseem ceeb yog:
- Yog koj yuav tau tuav ib tug qwj, txhob ua nws los ntawm rub lub plhaub, tab sis yog muab koj txhais tes kom nws sawv thiab ib txwm tuav tag nrho cov qwj tib lub sijhawm.
- Yog tias koj cov qwj nteg qe lawv yuav faus rau hauv thiab tawm tom qab 24 teev, nyob ntawm huab cua. Thawj cov zaub mov ntawm cov qwj me yuav yog lub plhaub ntawm lawv tus kheej lub qe thiab cov nyob ib puag ncig lawv tseem tsis tau hatched. Txij thaum ntawd los, kev saib xyuas zoo ib yam li hais rau cov neeg laus qwj. Nyob ib ncig ntawm ob xyoos lawv yuav pib rov tsim dua.
