Kaningi, eminyakeni yamuva nje, emadamini okwenziwa, ungabona ukuthi ngaphezu kwezinhlanzi, kuhlala nezinye izidalwa eziphilayo ezithakazelisa kakhulu. Futhi lezi yizinkalankala ezimfushane eziwolintshi, okuthi, yize zafika eYurophu kungekudala, sezivele ziqala ukuthola ukuthandwa okuphezulu phakathi kwama-aquarists. Ake sikucabangele ngokuningiliziwe.
Incazelo
Ifunwa yibo bobabili abaqalayo kanye nama-aquarists anolwazi, lo mhlali omangalisayo we-aquarium uyinzalo ye-crayfish ejwayelekile kakhulu. Kepha ukweleta umbala wakhe omangazayo hhayi esihlotsheni sakhe esikude, noma ngabe kubukeka kumangalisa kanjani, kepha nokukhetha okunzima. Ngakho-ke, uma ubhekisisa igobolondo lalo, ungabona kulo imivimbo emincane yombala omnyama namabala amnyama abekwe ngokungahleliwe.
Ngokuqondene nabamele abantu abadala, ngakho-ke, njengoba kungaqondakala vele egameni labo, abakwazi ukuziqhayisa ngosayizi abakhethekile. Kuyathakazelisa ukuthi, ngaphansi kwezimo zemvelo, abesifazane bafinyelela kuma-60 mm ubude, nabesilisa ngama-40-50 mm. Kepha akufanele kube nethemba lokuthi ukuba mncane kangaka kwenze lezi zinambuzane zingabi yingozi kangako. Ngakho-ke, wonke umdlavuza wesilisa unezinzipho ezinamandla impela ku-arsenal yawo, abawasebenzisa ngokushesha ukuthola ubuholi, ukuvikela indawo yabo, noma ukumane bahehe abesifazane. Ngokuqondene nabesifazane, uzipho lwabo alugcini nje ngokuba lincane kakhulu, kepha futhi lubuthaka kakhulu. Isilinganiso sobude besikhathi sokuphila edamini lokufakelwa le-patskurao cishe iminyaka emibili.
Ukuphila emvelweni
Njengoba kushiwo ngenhla, lezi zinambuzane ezingenamgogodla zazalaniswa ngokuzalaniswa okukhethiwe. Lokhu kwenziwa nguJ. Merino noB. B. Kebis emuva ngonyaka we-1943, ngokukhethwa kancane kancane kusuka kunkalankala ehlala eLake Lago de Patzcuaro, etholakala eMexico. Njengabazala babo abakude, ama-crayfish amancane nawo akhetha imizimba yamanzi emisha futhi emile. Bahlala, njengomthetho, eMexico, kepha kwesinye isikhathi bangatholakala kweminye imifula e-United States ngokugeleza okungasheshi kakhulu.
Okuqukethwe
Noma ngabe kungokwemvelo noma kokufakelwa, lo mdlavuza omncane awukhombisi ulaka olweqile. Ngakho-ke, akumangazi neze ukuthi kungenxa yesimo sabo se-phlegmatic, kokubili ezitshalweni ze-aquarium nokudoba, ukuthi lezi zingenamgogodla zithole ukufunwa okusabalele kangaka emhlabeni jikelele. Ukuphela kwento engaphazamisa isimo sabo esinjalo ukuba semkhunjini ofanayo nezinhlanzi ezinkulu kakhulu nezinolaka, ngokwesibonelo, i-catfish nama-cichlids. Kuyafaneleka futhi ukugcizelela ukuthi uma gazinga livela esitsheni sokufakelwa, ukufa kwabo okungenzeka kuvela kule crayfish kufanele kucatshangelwe.
Khumbula ukuthi akunconywa ngokuqinile ukubeka abamele abaningi kakhulu balezi zingenamgogodla ku-aquarium eyodwa, ngoba endaweni yabo yemvelo bahlala bodwa. Lokhu kuyiqiniso ikakhulukazi kwabesilisa, abangaqala ukukhombisa ulaka oluqinile ezihlotsheni zabo.
Inketho enhle ukuthenga owesilisa oyedwa nabesifazane abaningana.
Ngokuphathelene nomthamo we-aquarium, ivolumu encane ibhekwa ukuthi isuka kumalitha angama-60. Uma okuqukethwe kwabamele abambalwa balezi zinhlobo kuhlelwe, kuyadingeka ukuthi ucabange ngokwandisa amandla omkhumbi.
Ukuncoma
Njengomthetho, amatshe amancane omthunzi omnyama alungile njenge-substrate yalezi zinhlanzi, ezizogcizelela ngokuphelele umbala we-invertebrate. Ubukhulu obuncane be-substrate akufanele bube ngaphansi kuka-40 mm. Lokhu ukudala indawo enethezekile yezitshalo ezikhula e-aquarium.
Ama-aquarist anolwazi ancoma ukubeka amaqabunga e-oki ambalwa phezu kwenhlabathi, bese entwasahlobo uwashintshe abe ngamahlamvu wonyaka odlule. Futhi, ungakhohlwa ngesinye isici esithandekayo salezi zinhlanzi, okungukuthi, ukudabula ezindaweni zokukhosela ezahlukahlukene, ukunqwabelanisa amatshe noma izingwegwe eziphakathi.
Kungcono ukwenza ukukhanya kukhanye, futhi ugcine ukushisa kwamanzi kubanga lama-20-24 degrees nobulukhuni bamadigri ayi-10-15. Futhi, ungakhohlwa ngokwenza izinguquko ezijwayelekile zamanzi. Kunconywa ukuthi ukwenze kungadluli isikhathi esingu-1 ngezinsuku eziyi-7.
Okubalulekile! Ukudalwa kwezimo ezintofontofo zale crayfish akunakwenziwa ngaphandle kokuhlungwa kwekhwalithi ephezulu kanye ne-aeration.
Ukudla okunomsoco
Le crayfish yemifino izondla ngokuphelele ngayo yonke into engayifinyelela ngezinzipho zayo. Ngakho-ke, njengokuphakelwa kwayo, ungasebenzisa:
- Amathebulethi e-catfish, ama-shrimp.
- Ukudla okubukhoma.
- Ukudla okuqandisiwe.
Kodwa-ke, kubalulekile ukuthi wazi ukuthi lapho wondla ukudla okuphilayo, kufanele uqiniseke ukuthi ukudla kuwela phansi kwe-aquarium futhi akubhujiswa yizinhlanzi zasemanzini. Ngaphezu kwalokho, uma kufiswa, lawa angenamgogodla angadla imifino, kanti ukhukhamba noma i-zucchini kungasetshenziswa njengesibiliboco. Kepha khumbula ukubilisa imifino ngaphambi kokuyiphaka.
Ukuzala
Ukuvuthwa ngokocansi kulezi zingenamgogodla kwenzeka lapho zikhula zaba yi-1.5-2 cm ubude. Njengomthetho, lokhu kwenzeka lapho befika ezinyangeni eziyi-3-4. Iqiniso elithandekayo ukuthi abesifazane bavuthwa ngokocansi ngokushesha kunabesilisa, lapho, ngokungafani nabo, isikhathi sabo sokuphila sanda kancane. Inqubo yokuzalanisa uqobo ayidingi mzamo kusuka emanzini, kepha kuphela uma ukukhiqizwa kwawo kungenzeki echibini elijwayelekile lokufakelwa. Ngakho-ke, ukuze uvikele ukufa kwama-crustaceans amancane, kunconywa ngokuqinile ukufaka ama-invertebrate alungele ukukhwelwa emanzini ahlukile.
Ngemuva kwalokho, owesilisa uqala ukujaha insikazi ayithandayo kulo lonke ichibi lokufakelwa. Lapho efika kuye, uqala ukuhlangana naye. Kumele uqaphele ukuthi ukukhwelana kwenzeka cishe masinyane ngemuva kokuphothulwa kwe-molt. Kungaleso sikhathi lapho amaqoqo amaqanda abonakala esiswini sowesifazane eduze kwemilenze. Njengomthetho, akunzima ukuwabona ngenxa yobukhulu bawo nokukhanya kwawo.
Kumele uqaphele ukuthi lezi zinhlanzi azinandaba ngokuphelele nenzalo yazo yesikhathi esizayo. Ngakho-ke, ukuze silondoloze inani labo labantu, sibuyisela owesilisa emuva emkhunjini ovamile, kuthi kowesifazane sakhe indawo yokukhosela kusuka kubulembu noma kolunye uhlaza. Isikhathi sokufukamela sincike kakhulu ezicini ezithile:
- ukwakheka kwamakhemikhali kwemvelo yasemanzini;
- izimo zokushisa. Ububanzi obulungile bubhekwa njengama-24-26 degrees.
Kuyafaneleka futhi ukugcizelela ukuthi sonke lesi sikhathi owesifazane akuvamile ukuthi ashiye indawo yokuhlala. Ngakho-ke, kungakuhle ukuphonsa ukudla kungekude kakhulu nendawo okuyo. Ama-crustaceans amancane avela ngemuva kwe-molt yokuqala angamakhophi aqondile wabazali bawo. Kuyafaneleka futhi ukugcizelela ukuthi abukho ubunzima ekuzikhuliseni. Okudingekayo nje ukondla ngesikhathi futhi ungakhohlwa ukwenza ushintsho lwamanzi.
Ukuqothula
Njengama-crustaceans amaningi, lawa ma-spineless nawo angaphansi kwe-molting ngezikhathi ezithile. Njengomthetho, yile nqubo evumela ukuthi bakhule kancane. Ama-crayfish molt amancane kaningi (kanye ngesonto). Ngokuqondene nabantu abadala, le nqubo ibonwa kubo kaningi kakhulu. Kuyaphawuleka ukuthi umdlavuza osebenzayo awunakuzivikela nakancane. Ngakho-ke, kulesi sikhathi, kunconywa ukuthi ubhekele ukwakhiwa kwezindawo zokuhlala ezincane kuzo.
Futhi, i-molting ingahle ingaphumeleli ngaso sonke isikhathi. Ukuze lokhu kungenzeki, kuyadingeka ukuqapha ubukhona be-calcium ne-iodine endaweni yasemanzini. Kepha kufanele uqaphele ukuthi i-molting ihlale isivivinyo esinzima somdlavuza nganoma yisiphi isikhathi. Futhi umsebenzi omkhulu we-aquarist ukuwunciphisa kakhulu nokunciphisa izinga lokufa phakathi kwabo bonke abangenamathambo.
Izinhlobo
Namuhla, abamele umndeni wakwaCambarellus bangatholakala cishe kunoma iyiphi i-aquarium. Futhi lokhu akumangazi nakancane, ngenxa yokunakekelwa kwabo okungathobeki, omnivorous nosayizi omncane. Kepha kwesinye isikhathi abanye abasiki be-novice bacabanga ukuthi kukhona uhlobo olulodwa kuphela lwalezo zinambuzane ezingenamgogodla. Ngakho-ke, ake sicabangele ukuthi yiziphi izinhlobo zama-crustaceans amancane.
Umdlavuza we-dwarf tangerine (orange)
Umbala okhanyayo uyisici esivelele salolu hlobo. Itholakala ikakhulukazi eMexico. Okuqaphelekayo kwimvelo yemvelo, umbala womzimba wakhe nsundu, futhi kwaba orange ngemuva kokukhethwa. Isimo sepincer yesilisa sifana ne-lancet ngokubukeka. Izinga lokushisa elikhulu lemvelo yasemanzini lingama-15-28 degrees.
Okubalulekile! Ulaka kakhulu kwamanye ama-crustaceans.
I-crayfish yemifino emincane
Lezi zinhlobo zezilwane ezingenamgogodla zivame ukubizwa ngokuthi i-zublifar enamabala noma i-Cambarellus montezumae. izwe lakubo, kanye nozakwabo we-tangerine, yiMexico. Ngemibala egqamile, kunombala onsundu wokugcwaliswa okuhlukahlukene. Kwezinye izindawo, ungathola izindawo zomthunzi omnyama. Usayizi wabantu abadala ungafinyelela kuma-60 mm.
Njengomthetho, lezi zinhlanzi zingomakhelwane abanokuthula cishe zonke izinhlanzi. Kumele uqaphele ukuthi bangadla kuphela izinhlanzi ezifile. Bazizwa bekhululekile ngamadigri amanzi ayi-15-30.
Okubalulekile! Ngesikhathi se-molting, i-pygmy crayfish yaseMexico idinga isiphephelo.
Isikhukhula samanzi asemaxhaphozini
Lolu hlobo lwe-crustacean luhlala emanzini aseMississippi ekude. Ngokuqondene nombala wangaphandle, ungaba mpunga noma ube nsundu ngokubomvu ngemithende ebonakalayo noma enamagagasi atholakala kuyo yonke imhlane. Ngokuvamile kunendawo emnyama emnyama maphakathi nomsila. Usayizi omkhulu wabantu abadala ngu-40mm.
Kubalulekile futhi ukuqaphela ukuthi ukuzalaniswa kwalezi zinhlobo kudinga ukuba khona kwenhlabathi ekhethekile kuphela echibini lokufakelwa, kepha futhi namatshe, amaqabunga noma izigaxa ezibekwe kuwo. Lesi sidingo singenxa yokuthi ngesikhathi sokuzala inzalo, insikazi yommbila encane yensikazi igxuma ingene phansi icashe kuyo kuze kuvele ama-crustaceans amancane. Umbuso ofanele wokushisa wama-crustaceans anjalo ngama-20-23 degrees.
UTehanus
Enye yezinhlobo ezingavamile kakhulu zalezi zingenamgogodla. Okokuqala, kufanele uqaphele ukuthi yaqanjwa igama ngenxa yemidwebo yayo egobolondweni, okuthi, lapho ihlolisiswa, ifane namabala emabula. Umbala womzimba ungaba mnyama, nsundu noma luhlaza. Ihluke ngokukhululeka kwesondlo. Uzizwa kahle emazingeni okushisa amanzi kusuka ku-18 kuye kuma-27 degrees.
Ekuphetheni, ngithanda ukuqaphela ukuthi ngenxa yemvelo yabo engavamile nosayizi omncane, i-crayfish encane ayigcini ngokuba umhlobiso weqiniso wanoma iyiphi i-aquarium, kodwa futhi ikuvumela ukuthi uthole injabulo yangempela yobuhle ngokucabanga ngokuhamba kwabo ngokungcebeleka. Ngaphezu kwalokho, ngisho nalabo abaqala ukuqonda konke ubunzima be-aquaristics bazobhekana nokuqukethwe kwabo. Ukuphela kwento ongayenza ukunikela okungenani isikhathi sakho somuntu siqu ekunakekeleni izilwane ezifuywayo ezimangalisa kangaka.
