Ezinye izinhlanzi zingaphila ngaphandle kwamanzi kuze kube yizinsuku ezintathu, kodwa eziningi ziphila amahora ambalwa kuphela. Nakuba izinhlanzi zingaphila ngaphandle kwamanzi isikhathi esithile, isikhathi ezingase zikwazi ukuphila ngaphandle kwamanzi sincike ezinhlotsheni zezinhlanzi.
Inhlanzi ingaphila isikhathi esingakanani ngaphandle kwamanzi?
ama-sturgeon angaphila amahora amaningi ngaphandle kwamanzi. izinhlanzi eziningi zamanzi ahlanzekile kufanele zikwazi ukuma imizuzu embalwa, kodwa kufanele ukhulule i-hook ngokushesha ngangokunokwenzeka. Kuya ngokuthi inhlanzi ihlala imanzi. Isikhumba senhlanzi siyisitho esibalulekile sokumunca umoya-mpilo.
Inhlanzi ingaphila isikhathi esingakanani emhlabathini?
I-Carp, i-tench, i-barbel, i-crucian carp, izinhlanzi ezimhlophe ezihlukahlukene (kuye ngokuthi usayizi womzimba), futhi ikakhulukazi i-eel yizinhlanzi ezinamandla kakhulu futhi zingabhekana kahle nemizuzu embalwa emhlabeni!
Izinhlanzi zingaphila isikhathi esingakanani ngaphandle komoya?
Ukuphefumula komoya kungathatha amahora amabili. Ukuhlupheka okwengeziwe ngenxa yokushaqeka kwezinga lokushisa eqhweni. Izinhlanzi zivame ukukhombisa ukuzivikela, ukundiza, nokunyakaza kokubhukuda isigamu sehora kuze kube yilapho ukungakwazi ukuhamba kancane kungena, kodwa izinhlanzi aziqulekile.
Inhlanzi ingaphila isikhathi eside kangakanani ngaphandle komoya-mpilo?
Esihlungini sangaphakathi, amahora angu-2 nawo awayona inkinga. Kusukela emahoreni amabili, nokho, ingaqala ukuba yinkinga kusihlungi sebhodwe langaphandle. Amagciwane adla umoya-mpilo otholakalayo abese efa ngenxa yokuntuleka komoya-mpilo.
Ingakwazi yini ukuphefumula inhlanzi emhlabathini?
Kodwa kungani izinhlanzi zingakwazi ukuphefumula emhlabathini? Impela, abanawo amaphaphu njengabantu, kodwa ama-gill. Kodwa “umoya-mpilo ungamuncwa emoyeni ngamabhodlela, futhi ezinye izinhlanzi zenza kanjalo uma kudingekile,” kusho uJörn Gessner we-Leibniz Institute of Freshwater Ecology and Inland Fisheries.
Ingabe izinhlanzi zingahlala emhlabeni?
Kodwa akuwona kuphela ama-eels angaphila emhlabeni isikhashana. Kukhona nezinhlanzi ezinamaphaphu! Lezi zilwane zinawo womabili amathambo namaphaphu, okuzivumela ukuba ziphile emanzini angenawo umoya-mpilo ngokuza phezulu ukuze ziphefumule futhi zithole umoya-mpilo eziwudingayo emoyeni.

Ingabe izinhlanzi zingaphila egazini?
nxa | I-goldfish ingaphila izinyanga ngaphandle komoyampilo ngokuguqula i-pyruvate ibe i-ethanol ngokusebenzisa i-anaerobic metabolism. I-goldfish ingaphila emachibini asengadini aqandisiwe - ngo-0.5 ngenkulungwane yotshwala egazini.
Iziphi izinhlanzi eziphila ngaphandle komoyampilo?
Emachibini angashoni nasemachibini amancane, umoya-mpilo uvame ukusweleka emazingeni okushisa asehlobo. Kodwa-ke, i-goldfish ne-crucian carp, njengabakhileyo emanzini anjalo, abatholi kalula ukuphefumula. Lapho zishintshela ku-lactic acid fermentation, lezi zinhlanzi ze-carp zingahamba isikhathi eside zingenawo umoya-mpilo nhlobo.
Ungagcina isikhathi esingakanani izinhlanzi ebhakedeni?
Izinhlanzi nazo zingahlala isikhathi eside ezikhwameni zokuthutha. Ihora, isibonelo, alinankinga. Ngezinye izikhathi izinhlanzi nazo zithunyelwa ngezikhwama zokuthutha, lapho ukuthutha kuthatha isikhathi esingaphezu kwamahora angu-24. Izinhlanzi zisezikhwameni noma emabhokisini isikhathi eside lapho ziya kumthengisi.
Indlela yokugcina izinhlanzi ngaphandle kwepompo?
Njengama-labyrinth breathers, awancikile nje kuphela emoyeni osemanzini kodwa futhi angaphefumula phezulu. Bathanda amathangi "anokhula", angafinyelelwa kalula ngezitshalo ezingafuneki njenge-tomentosum, i-waterweed, izinhlobo zasemanzini, ama-cryptochromes angahlala amancane, nezitshalo ezintantayo.
Izinhlanzi zihlala isikhathi esingakanani embizeni?
Ukuthi inhlanzi yegolide emidala kangakanani echibini nase-aquarium yengilazi akuncikile ohlotsheni oluyisisekelo lwendawo yokuhlala - kunalokho, izimo zokugcinwa nokunakekelwa ukuze kunqunywe iminyaka yokuphila. Uma lezi zifanele lezi zinhlobo, inhlanzi enombala ogqamile ingaphila iminyaka engaba ngu-25.
Zidla malini izinhlanzi ngosuku?
Ungalokothi udle kakhulu ngesikhathi esisodwa, kodwa kuphela njengoba izinhlanzi zingadla emizuzwini embalwa (ngaphandle: ifolishi entsha eluhlaza). Kungcono ukondla izingxenye eziningana usuku lonke, kodwa okungenani ekuseni nakusihlwa.
Izinhlanzi zingaphila isikhathi esingakanani ku-aquarium ngaphandle kwesisefo?
Ungazondli izimfanzi kuze kube yilapho konke sekuphephile futhi. Ngingaphinde ngisuse isihlungi esinesici ngokuphelele, ngemva > kwamahora angu-24 ngaphandle kokugeleza okuzungezile, iningi lamabhaktheriya esihlungi cishe seliphelile futhi lidala umonakalo omkhulu kunokuba luwusizo. Bese kuba ngcono ukuqalisa isihlungi kusukela ekuqaleni.
Ingabe inhlanzi ingaphuza?
Njengazo zonke izidalwa eziphilayo emhlabeni, izinhlanzi zidinga amanzi ukuze imizimba yazo ne-metabolism isebenze. Nakuba zihlala emanzini, ibhalansi yamanzi ayilawulwa ngokuzenzakalelayo. uphuze izinhlanzi olwandle. Amanzi olwandle anosawoti ngaphezu koketshezi lomzimba wezinhlanzi.
