umdlavuza wapendwa

I-crayfish ependiwe, igama lesayensi i-Cambarellus texanus. Endle, iseduze nokushabalala, kodwa ezindaweni ezihlala emanzini ithole ukuthandwa okukhulu, okunomthelela ekulondolozweni kwalolu hlobo.

Iqinile futhi imelana nokushintshashintsha okuphawulekayo kwemingcele yamanzi kanye nezinga lokushisa. Ngaphezu kwalokho, lezi crayfish zinokuthula futhi kulula ukuzalanisa emanzini asolwandle ahlanzekile. Kubhekwa njengokukhetha okuhle kakhulu kwama-aquarists aqalayo.

habitat

Izwe le-Painted Cancer yiNyakatho Melika, insimu yezifunda ezisogwini lweGulf of Mexico. Inani elikhulu labantu liseTexas.

I-biotope evamile iyindikimba encane yamanzi amile enezitshalo eziningi. Enkathini eyomile, ngesikhathi sokucwila okuqinile noma ukomisa kwechibi, bangena emigodini ejulile egujwe kusengaphambili ekujuleni ngaphansi kosebe.

Incazelo

Abantu abadala bangamasentimitha angu-3-4 kuphela ubude futhi baqhathaniswa ngosayizi nezimfanzi ezincane ezifana namakristalu namaNeocardines.

Lo mdlavuza unemigqa eminingi emihle egobile, enamagagasi, kanye namachashazi. Isisu sinombala womnqumo ophaphathekile ofakwe iphethini enomugqa obanzi onomphetho omnyama.

Kukhona indawo emnyama ephawulwe kahle phakathi nomsila. Amachashazi amancane abonakala kuwo wonke umzimba, akha amaphethini amaningi nokuhluka kwemibala.

I-crayfish ehlotshisiwe inezinzipho ezi-oblong ezinhle nezincane.

Ubude besikhathi sokuphila iminyaka engu-1,5-2, kodwa kuyaziwa ukuthi ngaphansi kwezimo ezifanele baphila isikhathi eside nakakhulu.

Ukuchithwa kwenzeka njalo. I-crayfish endala ishintsha igobolondo elidala izikhathi ezi-5 ngonyaka, kuyilapho intsha ilivuselela njalo ezinsukwini ezingu-7-10. Ngalesi sikhathi, bacasha ezindaweni zokukhosela kuze kube yilapho ukuqina komzimba kuqina futhi.

Ukuziphatha Nokuhambisana

Nakuba bebhekwa njengabanokuthula, kodwa lokhu kuhlobene nezihlobo eziseduze kakhulu. Zibonakala ngokuziphatha kwendawo futhi zizovikela indawo yazo ekungeneni. Imiphumela yezingxabano ingaba buhlungu. Uma ama-crayfish egcwele ku-aquarium, wona ngokwawo azoqala "ukulawula" izinombolo zawo ngokubhubhisa abantu ababuthakathaka.

Ngakho-ke, kunconywa ukugcina i-crayfish eyodwa noma ezimbili ethangini elincane. Kuyamukeleka ukuhlala ndawonye nezinhlanzi zokuhlobisa.

Kuyafaneleka ukugwema izindawo zokuhlala ezinezinhlanzi ezidlayo ezinolaka, kanye nabahlali abakhulu abaphansi, njenge-catfish kanye nama-loaches. Zingaba yingozi ku-crayfish encane enjalo. Ngaphezu kwalokho, angababheka njengosongo futhi uzozivikela ngezindlela ezitholakala kuye. Kulokhu, ngisho nezinhlanzi ezinkulu ezinokuthula zingahlupheka (amaphiko, umsila, izingxenye ezithambile zomzimba) ezivela ezinzipho zayo.

Kunamaphuzu amaningi aphikisanayo mayelana nokuhambisana nezimfanzi. Mhlawumbe iqiniso likhona endaweni ethile phakathi. Uma kubhekwa ukuziphatha okuxekethile nokuziphatha kwezindawo, noma yiziphi izimfanzi ezincane, ikakhulukazi ngesikhathi sokuncibilika, zizobhekwa njengokudla okungenzeka. Njengezinhlobo ezihambisanayo, izinhlobo ezinkulu zingabhekwa njengezinkulu ngokuphawulekayo kune-Painted Crayfish. Isibonelo, izimfanzi ze-Bamboo, izimfanzi ze-Filter, izimfanzi ze-Amano nezinye.

Izici zokuqukethwe

Ubukhulu be-aquarium bukhethwa ngokusekelwe kwinani le-crayfish. Kumuntu oyedwa noma ababili, amalitha angama-30-40 anele. Ekwakhiweni, kubalulekile ukusebenzisa inhlabathi eyisihlabathi esithambile futhi uhlinzekele izindawo zokukhosela ezimbalwa ezenziwe ngezineke, amagxolo esihlahla, izinqwaba zamatshe nokunye ukuhlobisa kwemvelo noma kokwenziwa.

Ngezinga eliphezulu lokungenzeka, inkalankala izoshintsha indawo yangaphakathi, imbe phansi futhi ihudule izakhi zomklamo wokukhanya ukusuka kwenye indawo kuya kwenye. Ngenxa yalesi sizathu, ukukhethwa kwezitshalo kunqunyelwe. Kunconywa ukubeka izitshalo ngezimpande eziqinile futhi ezinamagatsha, kanye nokusebenzisa izinhlobo ezifana ne-Anubias, i-Bucephalandra, engakhula phezu kwama-snags ngaphandle kwesidingo sokutshala emhlabathini. Iningi lamanzi kanye nama-fern anekhono elifanayo.

Amapharamitha wamanzi (pH ne-GH) nezinga lokushisa akubalulekile uma kusebangeni elamukelekayo lamanani. Nokho, izinga lamanzi (ukungabikho kokungcola) kufanele libe phezulu njalo. Kunconywa ukushintsha ingxenye yamanzi ngamanzi ahlanzekile masonto onke.

I-Crayfish ayiwuthandi umsinga onamandla, umthombo wawo oyinhloko izihlungi. Inketho engcono kakhulu kungaba izihlungi ezilula ze-airlift ngesipontshi. Zisebenza ngokwanele futhi zivimbela ukumuncwa ngengozi kwe-crayfish esencane.

Ukudla

Badla yonke into abangayithola phansi noma babambe. Bakhetha ukudla okuphilayo. Isisekelo sokudla sizoba i-daphnia eyomile, entsha noma efriziwe, i-bloodworms, i-gammarus, i-brine shrimp. Bangakwazi ukubamba inhlanzi ebuthaka noma enkulu, izimfanzi, izihlobo, kuhlanganise nenzalo yabo.

Ukuzalanisa nokuzalanisa

E-aquarium, lapho kungekho zinguquko ezishiwo zesizini endaweni, ama-crayfish ngokwawo anquma ukuqala kwenkathi yokuzalanisa.

Abesifazane baphatha i-clutch ngaphansi kwesisu. Sekukonke, kungaba amaqanda ayi-10 kuye kwangama-50 ku-clutch. Isikhathi sokufukamela sithatha amaviki amathathu kuya kwamane kuya ngezinga lokushisa lamanzi.

Ngemva kokuchanyuselwa, amaphuphu ayaqhubeka nokuba semzimbeni wensikazi isikhathi esithile (ngezinye izikhathi kuze kube amasonto amabili). Umzwelo wemvelo uphoqelela insikazi ukuba ivikele inzalo yayo, futhi izingane ukuba zibe seduze kwayo ngokokuqala ngqá. Nokho, lapho umzwelo wemvelo uba buthakathaka, ngokuqinisekile iyodla inzalo yayo. Endle, ngalesi sikhathi, ama-crayfish amancane anesikhathi sokuya amabanga amade, kodwa endaweni evaliwe ye-aquarium ngeke abe nendawo yokucasha. Kuze kube yisikhathi sokuzalwa, insikazi enamaqanda kufanele ibekwe ethangini elihlukile, bese ibuyela emuva lapho izingane sezizimele.
