Ntawm no, txheej txheem ntawm kev yug me nyuam ntawm Achatina snails yog heev intensive. Lawv tsis tu cov qe nyob rau hauv cov qus, yog li ntawd ib tug loj tus naj npawb ntawm lawv tuag. Txawm li cas los xij, vim tias muaj ntau tshaj li ib puas qe hauv ib lub clutch, feem pua ntawm cov tub ntxhais hluas tseem muaj sia nyob yog loj. Vim yog,hais tias Achatina heev multiplied, lawv tau los ua kab tsuag ntawm cov tub ntxhais hluas cov qoob loo, raws li lawv noj lawv nyob rau hauv lub hauv paus.

Snails nyob hauv lawv qhov chaw ib puag ncig yog qhov kis ntawm cov kab mob uas txaus ntshai rau tib neeg. Tab sis Achatina, bred los ntawm txiv neej, tsis muaj kev phom sij, tsis muaj kab mob txaus ntshai hauv lawv.

Nyob rau hauv Nyiv, cov mollusks noj, yog li ntawd lawv bred nyob rau hauv loj. Fab Kis noj lawv thiab. Snails nyob rau hauv Russia yog bred li tsiaj. Hauv peb cov huab cua phem sab nraum zoov, lawv tsuas tsis muaj sia nyob.

Cov ntaub ntawv dav dav txog cov plhaub ntses

Achatina yog cov qwj neeg African loj tshaj plaws.

Nyob rau hauv lub plhaub muaj cov coils twisted clockwise thiab counterclockwise. Cov qwj qub muaj xya mus rau cuaj ntawm cov khoom dai ntawm lawv lub plhaub. Lub cev ntawm mollusks yog mos, wrinkled, nrog tubercles tshaj tag nrho saum npoo. Nws los nyob rau hauv ntau yam xim, tab sis cov qauv feem ntau yog alternating kab txaij nyob rau hauv contrasting hues.

horns me me ntawm ob khub yog lub cev kov ntawm Achatina. Lawv ob lub qhov muag nyob rau ntawm thawj khub horns. Nrog kev pab los ntawm lub teeb-rhiab hlwb pom thoob plaws hauv lub cev, qwj pom lub teeb. Mollusks pom cov khoom uas nyob ib centimeter deb ntawm lawv lub qhov muag. Lawv hnov tsw nrog lawv cov tawv nqaij, cov duab ntawm cov khoom nyob rau hauvnyob ze ze, perceived los ntawm ib leeg. Snails ua pa nrog lawv daim tawv nqaij, vim lawv tsis muaj ntsws.

How Qav mate

Txhawm rau kom tsis txhob muaj teeb meem thaum yug me nyuam Achatina snails thiab tu lawv, koj yuav tsum tsis txhob ua phooj ywg mollusks los ntawm tib lub masonry, uas lawv txhua tus txheeb ze rau ib leeg: niam txiv, kwv tij, muam, menyuam yaus. Rau kev yug me nyuam xaiv noj qab nyob zoo thiab loj snails yug hauv lwm tsev neeg. Txhawm rau kom cov me nyuam ua tau zoo thiab noj qab nyob zoo, ib hom thiab ntau hom mollusks tau sib xyaw.

Yog tias koj npaj yuav loj hlob qwj, tsis tas yuav maj nrawm nrog kev yug me nyuam. Qhov no yog vim lub fact tias thaum lub sij hawm cev xeeb tub, kev loj hlob thiab tsim ntawm molluscs nres. Kev sib yuav ua ntej ib xyoos yog qhov tsis xav tau.

Kev npaj rau kev tsim tawm

Nyob rau hauv kev cia siab ntawm cov xeeb ntxwv, nws yog ib qho tsim nyog los tsim cov xwm txheej rau kev yug me nyuam ntawm Achatina snails. Lub thoob dej yug ntses yuav tsum muaj qhov kub tsis tu ncua ntawm + 27 + 28 degrees. Nws qhov kev hloov pauv hauv lub sijhawm no yog qhov tsis lees txais.

Cov txheej txheem ua haujlwm li caskev yug me nyuam

Yuav kom yug tau Achatina kwj hauv tsev, lawv yuav tsum ua phooj ywg. Ua kom qhov no tshwm sim, lawv tau hloov mus rau hauv lwm lub thoob dej yug ntses lossis lub thawv. Yog tias cov tib neeg muaj qhov loj me, fertilization yuav yog ob sab, yog tias lawv cov kev txwv tsis sib xws, nws yuav yog unilateral. Qwj loj dhau los ua poj niam.

Mollusks thaum muaj hnub nyoog yau tsim cov txiv neej kab mob ntau dua li poj niam. Vim li no, rau txoj kev yug me nyuam, cov tub ntxhais hluas molluscs tau cog nrog cov neeg laus.

Snail mating kav ob teev lossis tsawg dua. Lawv cov kab mob sib deev kov ib leeg, sib pauv cov phev thiab fertilizing. Lub cev ntawm mollusk tuaj yeem khaws cia rau ob xyoos. Qws tuaj yeem nteg qe txhua lub hlis yog tias muaj kev pom zoo.

Tom qab mating, qe pib. Tam sim no paub tias tag nrho cov Achatina snails yog oviparous, txawm hais tias lawv txawv ntawm cev xeeb tub. Hatching qe yog pom meej yog tias koj saib nyob rau hauv lub spiracle ntawm mollusk. Ib mus rau ib thiab ib nrab hli dhau los txij thaum lub sij hawm mating tshwm sim, thiab mus txog rau thaum lub masonry qhib.

Yuav ua li cas txhawb nqa kev tsim tawm

Ntau tus neeg yug tshiab tshiab tau ntsib teeb meem zoo li no: txawm hais tias cov ntsiab lus zoo ntawm Achatina qwj, kev yug me nyuam tseem tsis tshwm sim. Yuav ua li cas? Koj yuav tsum pib los ntawm kev ua kom cov clams noj qab nyob zoo. Yog hais tias txhua yam nyob rau hauv kev txiav txim, hom ntawm lawv noj thiab muaj pes tsawg leeg ntawm cov zaub mov raug kuaj. Tom ntej no, cov xwm txheej ntawm kev kaw raug tshuaj xyuas,lub thickness ntawm lub substrate nyob rau hauv lub thoob dej yug ntses thiab nws cov mob. Yog hais tias lub litter tsis tau hloov mus ntev thiab nws tau ua qias neeg, yuav tsis muaj kev sib txuas thiab txuas ntxiv ntawm Achatina snails nyob rau hauv cov xwm txheej zoo li no. Cov kws paub txog yug me nyuam txhawb txoj kev yug me nyuam los ntawm kev tshem tawm lub pas dej dag.

Yuav ua li cas tu tus qwj thaum cev xeeb tub

Lub cev xeeb tub ntawm cov qe hauv ntau hom sib txawv raws sijhawm. Qhov nruab nrab, lub sij hawm no kav ib mus rau ob lub lis piam, tom qab ntawd tus qwj nteg 50-300 qe.

Thaum cev xeeb tub, molluscs siv ntau lub zog thiab lub zog, yog li tom qab txoj kev mating lawv feem ntau tsis ua haujlwm, burrow rau hauv av thiab tsaug zog ntau. Lawv txoj kev loj hlob thiab kev tsim tawm nres.

Lub sijhawm no, nws tseem ceeb tshwj xeeb tshaj yog tias cov clams tsis muaj calcium. Lawv yuav tsum tau noj nrog zaub mov chalk, calcium sib tov. Kev noj zaub mov yuav tsum suav nrog cov nplej sib xyaw, cov khoom noj protein thiab zaub.

Ib lub lis piam tom qab cov txheej txheem fertilization, koj tuaj yeem pom cov qe ntawm ntau daim. Lawv nyob ntawm ib sab ntawm lub qhov ua pa. Qhov no yog yav tom ntej masonry, uas cov qwj nteg nyob rau hauv av, txawm hais tias nws tshwm sim nyob rau hauv nws nto. Tsev neeg Achatina loj. Nws muaj mollusks uas tsis nteg qe. Me me me yug tam sim ntawd, 20-30 daim txog 9 hli loj.

Achatina snails:kev yug me nyuam, qe tu

Txhua yam tseem ceeb hauv kev ua liaj ua teb plhaub, tab sis cov txheej txheem ntawm kev yug me nyuam yog qhov pib ntawm lub neej. Yog li ntawd, nws yog ib qho tsim nyog los tsim cov kev mob siab tshaj plaws rau qhov no. Lwm qhov tseem ceeb sib npaug yog kev saib xyuas qe. Achatina snails, uas nws yug me nyuam tau ua raws li tag nrho cov cai, sai sai npog hauv qab ntawm lub thoob dej yug ntses nrog qe dawb. Ntawm cov no, qwj yuav hnia tom qab 65 hnub. Qee lub sij hawm lawv yuav nyob hauv av, noj qe qe. Ib tug neeg laus nteg qhov nruab nrab ntawm 50 qe nrog ib txoj kab uas hla ntawm tsib millimeters. Thaum yug me nyuam Achatina snails, qe tu tsuas yog tsim nyog. Yog tso tseg tsis muaj neeg saib, lawv yuav tuag. Yog li ntawd, cov cai hauv qab no rau kev saib xyuas lawv yuav tsum tau ua:

• Lub txaj los ntawm cov av hauv qab ntawm lub thoob dej yug ntses yuav tsum tsis txhob qhuav tawm, tab sis cov kua tsub zuj zuj ntawm cov dej kuj tseem tsim nyog. Yog dej npog lub zes, lub qe yuav lwj, thiab tag nrho cov embryos yuav tuag nyob rau hauv qhuav av.
• Qe tuaj yeem nchuav nrog av kom nyab xeeb.
• Hummidity yuav tsum khaws cia siab dua li ib txwm.
• Thoob plaws tag nrho lub sijhawm tso, yuav tsum tau saib xyuas qhov ntsuas kub. Lub thoob dej yug ntses yuav tsum sov dua hauv tsev.
• Koj yuav tsum tsis txhob khaws cov qwj ntau hauv ib lub tsev. Nyob rau hauv cov xwm txheej nruj, qe feem ntau tuag.
• Tsis txhob kov lawv ntawm koj txhais tes, txwv tsis pub koj tuaj yeem ua rau lub plhaub puas.

Lub qe qe twg hu ua cuav

Cov no yog cov qe uas tsis muaj menyuam hauv qhov nyiaj ntawm 10-15 daim. Lawv tsis muaj lub plhaub, lawv yog translucent nyob rau hauv tsos. Xws li qenpe fat. False masonry yog harbinger ntawm tus tiag, tab sis tsuas yog Achatina muaj ib khub. Tso qe rog tshwm sim hauv cov qwj kho siab.

qe ntau: yuav ua li cas?

Nws tshwm sim tias thaum yug me nyuam, Achatina cov qwj hauv tsev nteg qe ntau. Hauv qhov no, cov kws paub txog tsiaj txhu qhia kom khov cov khoom ntxiv, thiab tom qab ntawd tshem tawm lawv. Tab sis ib qho nthuav feature yuav tsum tau coj mus rau hauv tus account. Yog tias koj muab cov qe tso rau hauv lub thoob khib nyiab, txawm tias khov, lawv tuaj yeem ua rau cov qwj. Kev loj hlob ntawm cov pej xeem nyob rau hauv rooj plaub no yuav tswj tsis tau. Cov xwm txheej zoo li no tuaj yeem zam tau yog tias koj npaj ua ntej rau qhov xwm txheej zoo li no.

Tug kwj

Lawv hu ua Ghanaian qwj loj. Qhov no yog lwm hom av mollusk nyob rau hauv lub ntiaj teb no. Lawv nyuaj rau yug me nyuam dua li African Achatina. Tej vaj tse nyob yog hav zoov tuab ntawm Ghana thiab ntug hiav txwv thickets.

Cov plhaub taum 18 cm ntev thiab 9 cm inch. Muaj cov mob, txawm tias tsawg heev, thaum lub plhaub loj hlob mus txog 30 cm. Qhov nruab nrab ntawm lub neej yog 5-7 xyoo.

Nyob ntawm tsov qwj tsis ntev los no tau poob qis vim yog kev ua hav zoov hnyav heev. Tsis tas li ntawd, shellfish tau nquag siv los ua zaub mov. Nws kuj tseem ceeb tias tsov loj heev feem ntau tuag ntawm kev noj tsis txaus tom qab tso qe.

Nqaij ntawm lwm hom tsiaj feem ntau yuam kev rau tsov molluscs, uas nws qhov txawv yog cov tawv tawv ntawm qhov tsaus ntuj.xim, qhov kawg uas muaj V-shape.

Kev yug me nyuam ntawm Achatina tsov qwj tshwm sim thaum lawv ncav cuag kev sib deev, uas yog, lawv lub hnub nyoog yog 21-24 lub hlis, qee zaum peb xyoos. Tab sis lub sij hawm no raug txo yog tias, thaum khaws cia hauv tsev, nws yog qhov zoo los pub koj tus tsiaj. Qee zaum kev yug me nyuam tshwm sim nrog kev pab ntawm tus kheej fertilization, tab sis nws kav ntev. Nws tshwm sim tias tsib xyoos dhau los tom qab tus qwj tso nws cov qe thawj zaug.
