I-Zebrafish yizilwane ezifuywayo ezincane futhi ezisebenza kakhulu ezikhetha ukuhlala emihlambini. Lezi zinhlobo zazingezokuqala ukutholakala ezindaweni zasemanzini zasekhaya. Izinhlanzi ziyaphila, azithobeki, kuyathakazelisa ukuzibuka, futhi noma oqalayo angakwazi ukuphatha ukuzalanisa.
Incazelo
I-zebrafish yachazwa okokuqala ngo-1822. Izwe lakubo lingamachibi ase-Asia, Nepal naseBudapest. Inhlanzi inezinhlobo eziningi zokukhetha umbala nezimo zokuphela. Kusukela esithombeni ungaqonda ukuthi le nhlobo ihluke kanjani.
Umzimba we-zebrafish unesimo esivulekile, esicwecwe ezinhlangothini zombili. Kukhona amadevu amane azungeze izindebe. Isici esihlukile yimivimbo eluhlaza okwesibhakabhaka nokumhlophe eqala kuma-operculum futhi iphele ekugcineni kwe-caudal. I-anal fin nayo ihlotshiswe ngemivimbo, kepha yonke eminye ayinambala ngokuphelele. Ubude obukhulu babantu abadala ikakhulukazi ama-6 cm, kepha kuyaqabukela bafinyelele osayizi abanjalo kuma-aquariums. Isikhathi sokuphila sifushane - size sifike eminyakeni emi-4. Kunconywa ukugcina okungenani abantu aba-5 ku-aquarium eyodwa.
Izinhlobonhlobo
Ngemuva kokubuka isithombe, ungaqagela ukuthi lezi zinhlanzi zinezinhlobo eziningi. Kodwa-ke, yi-zebrafish kuphela eshintshwe izakhi zofuzo. Abamele abanjalo babizwa nangokuthi iGloFish. Isici se-fluorescent sangeniswa ezinhlwini zofuzo zalezi zinhlanzi. Le ndlela i-danio rerio pink, eluhlaza kanye ne-orange ivela ngayo. Zihlukaniswa ngombala wazo ogqamile, oba namandla ngokwengeziwe ngaphansi kwethonya lemisebe ye-ultraviolet. Okuqukethwe nokuziphatha kokunhlobonhlobo okunjalo akuhlukile kokudala.
Umbala obomvu utholwe ngokwethulwa kwe-coral DNA, izinhlanzi eziluhlaza zaba ngenxa yezakhi zofuzo ze-jellyfish. Futhi abamele ophuzi-olintshi batholakala nale DNA emibili.
Ukugcinwa nokondliwa
Ekugcineni i-zebrafish, i-rerio ayihloniphi ngokuphelele. Zingangena ngokuphelele ngisho nakuma-nano aquariums. Ngomhlambi wabantu aba-5, kudingeka amalitha ama-5 kuphela. Banamathela ezingxenyeni ezingenhla zamanzi futhi bathanda ukugxuma, ngakho-ke ithangi kufanele livalwe ngesembozo. Izinhlanzi ziyadlala kakhulu, kepha zihlala zinamathele ndawonye, ezingabonakala ngisho nasesithombeni.
Qiniseka ukuthi utshala izitshalo, kodwa uzibeke ekhoneni elilodwa ukuze i-zebrafish ibe nendawo eyanele yokubhukuda. Nikeza ukukhanyisa okuhle.
Izidingo zamanzi:
- Ukushisa - kusuka kuma-degree angama-18 kuya kwangu-26.
- Ph - kusuka ku-6.6 kuye ku-7.4.
Emvelweni wazo wemvelo, izinhlanzi zondla imbewu yezitshalo ewele emanzini, izinambuzane ezincane kanye nezibungu zazo. Ekhaya, baba cishe omnivorous. Noma ikuphi ukudla okubandayo noma okufakelwayo kuzokwenza. Kukhethwa i-Artemia ne-tubifex. Qaphela ukuthi babamba kuphela izingcezu zokudla ebusweni bamanzi. Konke okucwila phansi kuzohlala lapho.
Ubani ongakhetha njengomakhelwane?
I-aquarium fish zebrafish rerio ayinalo nolaka ngokuphelele, ngakho-ke ingazwana cishe nanoma yimuphi umakhelwane. Ephaketheni, bangasukelana, kepha lokhu kungukubonakaliswa kobudlelwano bezikhundla obungadluleli kwezinye izinhlobo zanoma iyiphi indlela. UDanios uphelele ukugcina ku-aquarium eyabiwe. Ngeke kubangele noma yimuphi umonakalo ngisho nasezinhlotsheni ezihamba kancane nezolile. Into esemqoka ukuthi azikho izilwane ezizingelayo phakathi komakhelwane abangabona izinhlanzi ezincane njengokudla. Kuyabonakala esithombeni ukuthi i-zebrafish incane ngokwedlulele, kepha, ngenxa yejubane nokungezwani kwabo, bangazwana ngisho nomakhelwane abanolaka njengama-cichlids (aphakathi nendawo), gourami, scalars.
Ihlanganiswe ngokuphelele nezinhlanzi ezincane - ama-guppies, ama-macropods, i-rassbora. Futhi efanelekayo indima omakhelwane ameva, okhadinali kanye nannostomuses.
Ukulungiselela ukuzala
Ukuzalela i-zebrafish kuyinqubo elula ngisho nomuntu oqalayo angayiphatha. Izinhlanzi zifinyelela ekuvuthweni ngokocansi ezinyangeni ezi-4-6. Futhi ungaqala ukuzalanisa nganoma yisiphi isikhathi sonyaka.
Ngaphambi kokuzala, i-zebrafish iyiswa ku-aquarium enkulu (kusuka kumalitha ayi-10), izinga lokushisa lamanzi kufanele libe ngaphezu kwama-20 ° C. Yondla izinhlanzi kakhulu. Ngalezi zinhloso, i-red daphnia nezibungu zegazi zihle kakhulu. Ukudla kufanele kube bukhoma.
Umhlabathi ezindaweni zokuzalela ungazikhethela. Ama-aquarists amaningi akhetha iziqukathi ezinendawo esobala yokuqapha ukuzala nokwakhiwa kwesibungu. Kepha awukwazi ukuyishiya ingenalutho ngokuphelele. Iphansi limbozwe yizindawo ezingamaxhaphozi noma i-fontinalis, ecindezelwa phansi ngokuthile. Amanzi wezindawo zokuzalela athathwa emanzini ajwayelekile lapho kuhlala khona izinhlanzi. Qiniseka ukufaka isiphon esitsheni. Kungcono ukubeka i-aquarium efasiteleni ukuze kube khona ukukhanya kwelanga eliqondile.
Kukhethwa abesilisa nabesifazane abaningi ngokuzalaniswa. Kungcono ukuwabeka ezindaweni zokuzalela kusihlwa. Ebusuku bazokwazi ukuhlala endaweni entsha, kuthi ekuseni, lapho kuqala ukuntwela kokusa.
Ukuzala
Ake siqhubeke nesihloko esithi "zebrafish rerio - reproduction". Kuyathakazelisa kakhulu ukubona inqubo yokuzala. Izinhlanzi zihamba ngokushesha okukhulu zizungeze i-aquarium, zindiza ngokoqobo. Lapho owesilisa ekwazile ukuhlangana nensikazi, uyishaya esiswini, okuvela kuwo amaqanda, akhiphe nobisi uqobo. Ukuzala kudonsa cishe ihora. Ngalesi sikhathi, amamaki amaningana angenzeka ngezikhathi zemizuzu engu-6-8. Ngalesi sikhathi, insikazi ingabeka amaqanda asukela kuma-60 kuye kwangama-400.
Izinsikazi ezimbili nazo zingafakwa ezindaweni zokuzalela, kepha lapho-ke inzalo izovela incane. Ngakho-ke, uma ufuna ukuthosa okwengeziwe, lungiselela amathangi amaningi okuzalanisa.
Lapho ukuzala sekuphelile, abesilisa nabesifazane bayasuswa "esidlekeni" futhi bahlala eziqukathi ezahlukahlukene. Umaki uyaphindwa ngesonto, ngaphandle kwalokho i-caviar izovuthwa ngokweqile. Owesifazane oyedwa, kuze kufike ku-6 litter kuyinto ejwayelekile. Uma, ngesikhathi sokuzala, efihla kowesilisa, amaqanda akhe awakalungeli okwamanje noma asevele avuthwa ngokweqile. Kunoma ikuphi, izinhlanzi zishiywa ezindaweni zokuzalela ezinye izinsuku ezimbili.
Isikhathi sokufukamela sithatha izinsuku ezimbili. Ngemuva kwalokho ama-fry azalwa, angabonakala esithombeni esingezansi. Zincane kakhulu, ngakho-ke kudingeka uqaphele lapho uhlanza i-aquarium. Ekuqaleni, abasha bondliwa ngama-ciliates ne-yolk yeqanda. Njengoba izingane zikhula, zidluliselwa kokuphakelayo okwengeziwe.
