Peb nyiam crayfish nyob rau hauv peb lub teb chaws rau npias thiab cia li nyiam li ntawd, txawm cov me nyuam zoo li lawv cov nqaij npuas av. Cov kiv cua ntawm cov ntaub qhwv crayfish tuaj yeem npaj cov txheej txheem ntawm lawv cov qe, uas dhau sij hawm tig mus ua lag luam. Loj hlob hlob hauv tsev tsis yog nyuaj heev thiab tsis kim, tab sis ntev. Nws yuav pib coj nyiaj tau los rau xyoo ob, thiab yuav them rau nws tus kheej li ntawm 6 xyoo.
Muaj ib qho kev xav tau ntawm qhov khoom no, qhov kev sib tw tsis zoo li ntawd, thiab cov nyiaj tau los ntawm cov lag luam tsim zoo thiab cov lag luam tsim zoo yog qhov ruaj khov. Piv txwv li, ib tug neeg so hauj lwm uas muaj peev xwm tswj tau yog muaj peev xwm tswj tau qhov zoo li no, yog nws nyiam nws.
Qhov twg thiab qhov twg cov kab xaum qhuav yuav ua rau yug me nyuam
Nws yog ib qho ua tau kom yug crayfish tsis tsuas yog nyob rau hauv tej yam ntuj tso los yog nyob ze rau lawv, uas yog, nyob rau hauv ntug zos, tab sis kuj nyob rau hauv ib qho chaw tsim artificially, piv txwv li, Aquariums - nyob rau hauv lub nroog tej yam kev mob.
Cov ntaub ntawv ntawm lub koom haum ntawm cov vaj tse thiab cov kev cai ntawm kev raug txim tsis yog ib qho lus qhia. Thaum sau lawv tus kheej, lawv kawm txog cov ntawv nyeem tshwj xeeb thiab npaj cov qoob loo ntawm cov hauv qab. 
Yuav pib ua lag luam, peb yeej xav tau cov kab mob crayfish. Lawv tuaj yeem ntes koj tus kheej los yog yuav. Zoo tag nrho - lub acquisition ntawm larvae - tsis yeej ib txwm ua tau. Ib qho kev xaiv ntau dua yog xav yuav cov neeg laus cov laus thiab tsa lawv cov me nyuam.
Cov chaw ntawm cov neeg tau txais kabmob kheesxaws:
- Nuv ntses rau hauv dej los yog pas dej.
- Khw nyob tom tsev khw.
- Purchase rau ib qho ua liaj ua teb tshwj xeeb.
Koj puas paub? Salted crustacean caviar yog ib lub tais qab muaj ntau yam khoom xyaw: piv txwv, protein, phosphorus, iron, cobalt, thaum nws cov ntsiab lus caloric tsawg heev.
Muaj hom crayfish nrov tshaj plaws thiab xav tau:
- Xiav Cuban - yog kev loj hlob sai thiab omnivorous, prefers kub tsis tshaj 26 ° C;
- Australian - yog cov hom tsiaj feem ntau, tuaj yeem bred hauv thoob dej yug ntses, yuav tsum tau kev saib xyuas tshwj xeeb thiab kom paub zoo;
- Marble - xav tau cov cheeb tsam loj thiab txias kub, hermaphrodite.
Tam sim ntawd ntau tus neeg yuav tsum tsis txhob yuav: cov kev xav tau ntawm ib lub me ua liaj ua teb yuav tsum txaus siab ntawm 4 tug txiv neej thiab 8 tus menyuam ntxhais, uas tuaj yeem pom zoo rau thaum caij nplooj ntoos hlav los ntawm cov qe hauv qab.
Nws yog ib qho tseem ceeb heev uas yuav tau soj ntsuam qhov sib piv ntawm cov txiv neej rau poj niam nyob rau hauv ib qho ratio ntawm 1: 2.
Yuav ua li cas yug crayfish
Rau kev yug me nyuam ua ke, koj tuaj yeem siv lub ntuj tsim tsis txaus, tsim kom muaj ib qho khoom plig uas ua tau raws li tag nrho cov kev tsis zoo rau lub tswv yim, koj tuaj yeem ua qhov no hauv nroog npav, loj zuj zus rau hauv cov dej haus. Txhua yam ntawm cov hau kev no zoo, thiab txhua yam nws muaj nws tus yam ntxwv thiab qhov tsis zoo.
Yug me nyuam hauv cov reservoirs
Lub pas dej - tej yam ntuj tso thiab tsim chaw rau crayfish. Nyob rau tib lub sijhawm nws yuav tsum yog dej huv, nyob rau hauv ib qho kev tsis zoo, yog tias nws tsis tuag nkaus, nws yuav txo qis.
Nws tseem ceeb heev! Crayfish yuav tshwm sim nyob rau hauv parallel nrog ntses, tab sis nws yog advisable kom tshem tawm los ntawm cov tsaj txhuv pas dej uas pub on crayfish thiab lawv caviar.Nyob rau hauv lub caij ntuj no, lawv yuav tsum tau hibernate, thaum tsis kam noj. Lawm, qhov nyhav ntawm lub sij hawm no txo. Nyob rau hauv cov cheeb tsam uas winters yog tsiag ntawv los ntawm loj heev frosts, qhov yug me nyuam ntawm crayfish nyob rau hauv lub pas dej yog impractical: lub reservoir freezes mus rau nram qab kawg, thiab cov tsiaj txhu tuag.
Yug me nyuam hauv lub pas dej muaj qhov zoo:- tus nqi ntawm tuav lub pob zeb hauv lub xeev tsim nyog tsis dhau siab;
- hauv pas dej, dej purification tshwm sim lawm;
- Cov tsiaj txhu kuj tsis tas yuav muaj nuj nqi ntau dua vim khoom noj khoom haus.
Disadvantages ntawm hom no:
- ntev lub sij hawm ntawm txoj kev loj hlob ntawm kev sibtham;
- tsawg ntu ntawm cov tsiaj nyeg rau ib cheeb tsam twg;
- ntev ua lag luam.
Rau ib tug zoo noj qab nyob zoo nyob rau hauv lub pas dej tsiaj yuav tsum tau cov nram qab no mob:
- Lub cheeb tsam ntawm aub tsiv los ntawm 50 square meters, nws tob ntawm 2 meters.
- Nws yog ntshaw tias lub pas dej nyob ntawm nws tus kheej qhov chaw kom tsis txhob muaj teeb meem nrog cov neeg ua dej caw.
- Nyom yuav tsum cog ib ncig ntawm ib ncig ntawm lub qhov taub.
- Lub ntug yuav tsum av nplaum.
- Lub qab yuav tsum tau nruab nrog pob zeb, sprinkled nrog xuab zeb rau ntawm vaj tse thiab kev tsim ntawm qhov.
Cov pob txha tsim tau tsim yuav tsum muaj nyob rau ntawm theem tsim kho nrog cov kua dej kom tswj tau cov dej thiab qhov hloov ntawm nws lub cev. Dej xav tau kev hloov rov qab, uas tau ua txhua hli hauv tus nqi ntawm 1/3 ntawm tag nrho.
Nws tseem ceeb heev! Nyob rau hauv tsis muaj cov ntaub ntawv yuav tsis hloov cov dej kom meej, nws yuav muaj ib tug detrimental nyhuv ntawm lub prevailing microclimate thiab fraught nrog poob ntawm tsiaj txhu.
Kev sib ceg hauv kev haum ntawm ib qho khoom pov thawj:
- nws cov creation tsis tau loj heev cov nqi;
- qhov kev noj haus yog kawm tau los ntawm lub ntuj tsim, uas txuag ntawm kev yuav khoom noj;
- laboriousness ntawm tus txheej txheem yug me nyuam.
Kev sib ceg uas ua rau koj xav txog kev ua tau ntawm kev ua qoob loo nyob rau hauv ib qho khoom pov thawj:- tsis yog tag nrho cov cheeb tsam yog haum rau kev lag luam no - ib qho yuav tsum tsis txhob cia qhov kawg khov ntawm pas dej nyob rau lub caij ntuj no;
- kev poob siab ntawm kev tsim kho ntawm lub reservoir nyob rau hauv ib qho chaw tshav ntuj;
- tau muaj teeb meem hauv kev xaiv ib qho chaw;
- tsawg ntom ntawm qhov chaw nyob ib square meter
- tsis muaj peev xwm tswj tau kub.
Yuav tsum tau ua kom tau los ntawm ib qho khoom pov thawj:
- Sandy los yog ntug hiav txwv los ntawm ntug hiav txwv, tsaus los ntawm zaub.
- Stony qab.
- Ntxuav thiab environmentally friendly.
- Muaj peev xwm los tsim nyob rau hauv qab ntawm lub qhov.
- Tsis muaj cov qog.
Populating ib pas dej nrog crayfish yuav tsum tsis pub dhau lub ceev ntawm lawv tsaws. Qhov zoo tshaj plaws kev xaiv yog qhov ntom ntawm 5 mus rau 7 daim ntawv luam tawm ib lub 'meter' square. Tom qab ntawd, cov kws ua laj ua teb muag pom cov qauv no, txawm li cas los, thaum pib lub lag luam, nws yuav tsum ua raws li lawv.
Nws yog tawm tswv yim rau yug breeds uas loj hlob sai sai - cov neeg uas yog bred rau dag yug tsiaj txhu.
Ib tug poj niam tuaj yeem ua tau li ntawm 30 units ntawm cov me nyuam. Txawm li cas los xij, lawv yuav loj hlob mus rau lub xeev yam tsis tau ua ntej tshaj peb, tab sis ntau zaus hauv 6 xyoo, yog li ib tug yuav tsum muaj kev txawj ntse thiab kev ua siab ntev rau kev yug kab hauv tsev. 
Thoob Dej Yug Me Nyuam
Qoob loo ntawm crayfish nyob rau hauv ib thoob dej yug ntses pom tseeb cov neeg mob uas cov pawg ntseeg yuav tsum tau muab. Ntshe microclimate nyob hauv cov thoob dej yug ntses yuav cia koj tau txais cov nyiaj khwv yees txhua lub sijhawm xyoo.
Yuav kom npaj tau cov kab mob khees xaws koj xav tau ib chav, koj tuaj yeem xauj nws.
Lub ntim ntawm cov dej caw yuav tsum yog yam tsawg 250 liters. Hauv qab no yog nruab nrog pob zeb, xuab zeb, av nplaum, snags - qog lub vaj tsev ntuj tsim. Rau cov kev ua zoo yug me nyuam aquarium yuav tsum muaj peb: rau cov neeg laus, rau mating thiab rau cov hluas.
Qhov ceev ntawm cov thoob dej yug ntses yuav muaj txog li 350 copies ib square meter. Tus qauv ntawm cov dej yug me nyuam yuav tsum muaj ib tug neeg ua lag luam ib qho zoo me ntsis sij hawm uas nws muaj peev xwm devote rau lawv cov tsiaj.
Nws tseem ceeb heev! Lub peculiarity ntawm yug me nyuam crayfish nyob rau hauv ib thoob dej yug ntses yog hais tias lawv tsis tas yuav hibernate thiab nce hnyav sai npaum li cas.
Habitat samfwm kom ua raws li cov hauv qab no:
- zoo kub;
- lim dej huv si nrog cov pa oxygen;
- kuas pub;
- vitamin ntxiv.
Qhov tsis zoo yog qhov cheeb tsam los ntawm qhov loj ntawm lub thoob dej yug ntses. Txhawm rau tsim kom muaj ntau ntxiv, yuav tsum muaj chaw nyob.
Nws tseem ceeb heev! Qhov qis tshaj plaws pub rau cov crayfish yog -1 ° C: ntawm no kub, lawv tsis tuag, tab sis lawv tsis hloov.
Yuav ua li cas pub lub crayfish
Crayfish yog cov herbivorous tsiaj txhu, tab sis nyob rau hauv cov xwm lawv muaj peev xwm muaj ntau yam organic tshua, carrion hauv lawv cov zaub mov. Nrog rau cov zaub mov tsis muaj peev xwm ua tau. Feem ntau, lawv noj txhua yam uas lawv muaj peev xwm ncav cuag, vim lawv tsis yog neeg tua tsiaj. 
Nyob rau hauv qhov, nws yog:
- earthworms;
- ntau yam zaub ntsuab;
- kab cov kab laum;
- me ntses thiab qwj.
Tom qab uas tau tuav cov tsiaj txhu los ntawm kev pab los ntawm kev ntses, lawv tawm ntawm cov ntawv me me thiab noj lawv. Obviously, arthropods pub rau lawv cov xwm txau - noj cov kab mob cancer hauv tsev tsis yog qhov nyuaj.

Luam (mating) ntawm crayfish
Cov phooj ywg Crayfish txhua xyoo, ntau zaus hauv lub caij nplooj zeeg. Ib tug poj niam tsim tawm 110-480 qe, feem ntau ntawm cov tuag uas tsis tas yug. Qhov nruab nrab ntawm cov qog nqaij hlav rau cov neeg laus yog ua los ntawm ib tug poj niam yog 30.
Tus poj niam me me loj tshaj tus txiv neej. Lub tom kawg muaj ob chav khub ntawm lub plab ze ntawm lub plab, uas nws ua tus khub thaum lub caij fertilization. 
Kev tu plaub muag tsis tau siv: tom qab tus neeg koom nrog tus khub, tus txiv neej ua rau nws thiab sim ua rau fertilize, tus poj niam xav kom tsis txhob hu ntau heev tias txoj kev ua mating yuav kim nws lub neej.
Lub plab yog fertilized hauv nws lub cev, yog hais tias tus khub muaj zog, tom qab uas nws tam sim ntawd nkag mus rau hauv nws burrow thaum nruab hnub, thaum kev sib deev aggression ntawm cov txiv neej vam meej, yog ntshai tawm nws.
Koj puas paub? Ib tus txiv neej zoo tib yam yeej npog tau ob tug poj niam, thiab qhov no nws hnav kom nws muaj peev xwm noj nws tus kheej thib peb tus khub tom qab fertilizing.
Feem ntau cov txiv neej tsis noj ib feem hauv kev yug me nyuam - kev saib xyuas ntawm cov me nyuam yaus nkaus rau hauv leej niam.
Txog ib hlis tom qab fertilization, tus poj niam spawns. Nyob rau hauv rooj plaub no, lub qe yog glued mus rau pseudopods on lub plab mus txog rau larvae ntawm lub qe hatch. Qhov no yog ib lub sijhawm nyuaj rau leej niam lub neej yav tom ntej: nws yuav tsum tau muab cov qe nrog oxygen, ua haujlwm tsis tu ncua nrog tus Tsov tus Tuag, tiv thaiv lawv ntawm cov tsiaj tua tsiaj, thiab ua zoo tu cov txheej txheem los ntxuav cov pwm, av nkos thiab algae. Nyob rau hauv qhov no ntawm lub caviar ploj thiab tuag. 
Nyob rau qhov zoo tshaj plaws, nws txuag 60 qe, los ntawm uas cov larvae yuav muaj. Tom qab ib lub lim tiam los yog ob, lawv pib tawm ntawm leej niam, zais los ntawm kev piam sij ntawm sab nraud ntiaj teb hauv qab nws tus nplais, thiab tawm ntawm nws tom qab ib hlis los ob. Lub sijhawm ntawd, ntev npaum li 3 xees, thiab lawv tau txais kev paub txog kev ciaj sia.
Nyob rau hauv ntuj tsim, 10-15% ntawm lawv yuav ciaj sia, tab sis nrog txaus noj haus nyob rau hauv khoom neeg tsim tej yam kev mob, txuag cov masonry - 85-90%.
Cancer pib puberty thaum muaj hnub nyoog 3 xyoos. Qhov loj ntawm tus poj niam yuav tsum tsis txhob yuav tsawg tshaj 67 millimeters. Tus txivneej hlob zoo dua, txwv tsis pub nws yuav tsis paub nrog cov ntaub ntawv tu tub tu kiv.
Noj rau hauv tus account kev nyuaj ntawm reproduction ntawm arthropods nyob rau hauv cov qus, peb pom lub expediency ntawm lawv cov khoom neeg tsim yug me nyuam.
Molting crayfish
Molting lub sij hawm yog heev txaus ntshai rau cov neeg. Tsis tsuas yog lub plhaub sab nraud pov tseg, tab sis kuj yog npog qhov muag, qhov muag, txoj hlab pas thiab cov kaus hniav, nrog rau qhov mob khees xaws khoom noj. Qhov tsuas yog khoom uas tseem tshuav nrog nws - gastroliths - mineral formations uas muaj qhov zoo ntawm lub lens. Lawv nyob rau hauv lub plab ntawm tsiaj thiab yog qhov chaw ntawm txuam nrog calcium, uas tus tsiaj siv los cog loj ntawm lub cev.
Koj puas paub? Qhov ncig saib tau hu ua "crayfish pob zeb" nyob rau hauv Nrab Hnub nyoog. Lawv raug suav ua ib qho txuj ci tseem ceeb uas kho tau txhua yam kab mob.
Hlav cancer yog mos thiab ua kom tsis muaj kev tiv thaiv kiag li: vim li no, nws nyiam kom zaum tawm lub sijhawm txaus ntshai nyob rau hauv lub burrow, thiaj li tsis mus ua cov neeg txheeb ze thiab cov neeg txhoj kas poom.
Nyob rau hauv thawj xyoo ntawm lawv lub neej, raws li lawv loj hlob sai sai, lub crayfish hloov lub plhaub 8 lub sij hawm, nyob rau hauv lub xyoo ob ntawm lub neej nws tshwm sim 5 lub sij hawm, nyob rau hauv ib xyoos tom ntej - ib zaug los yog ob zaug hauv ib xyoos. Thawj xyoo feem ntau tuag thaum lub sijhawm thawj zaug, txog 10% nyob rau lub hnub nyoog lag luam ntawm sab nraud.
Thaum lub plhaub tsis khov lawm, qhov kabmob hauv nws cov burrow loj hlob sai, tab sis nws tsis noj dab tsi. Tom qab ua kom tiav ntawm lub plhaub, qhov kev loj hlob nres kom txog thaum hloov tom ntej ntawm cov ris tsho.
Qhov loj tshaj plaws txiv neej tuaj yeem mus txog 21 centimeters, cov pojniam - txog li 15 centimeters.
