I-giant arapaima (lat. Arapaima gigas) akunakubizwa ngokuthi inhlanzi ye-aquarium yasekhaya, ngoba inkulu kakhulu, kepha futhi akunakwenzeka ukungasho ngayo.
Ngokwemvelo, ngokwesilinganiso ifinyelela ubude bomzimba obungu-200 cm, kepha izinhlobo ezinkulu, ezingaphezu kwamamitha ama-3 ubude, nazo zibhaliwe. Futhi ku-aquarium incane, imvamisa cishe i-60 cm.
Le nhlanzi esabekayo yaziwa nangokuthi i-piraruku noma i-paiche. Isidlakela esesabekayo esidla kakhulu izinhlanzi, ngokushesha nangokushesha.
Angakwazi futhi, njengokuthile okufana ne-arowana yakhe, angagxuma emanzini abambe izinyoni nezilwane ezihleli emagatsheni ezihlahla.
Vele, ngenxa yobukhulu bayo obukhulu, i-arapaima ayizilungele kahle izindawo zasemanzini, kepha ivame ukubonakala emibukisweni yama-zoo nase-zoo, lapho ihlala emachibini amakhulu, isitayela njengezwe layo - i-Amazon.
Ngaphezu kwalokho, kuvinjelwe nakwamanye amazwe, ngenxa yengozi yokuthi, uma idedelwa imvelo, izobhubhisa izinhlobo zezinhlanzi zemvelo. Asibhekani nalokhu, ngenxa yezimo zezulu.
Okwamanje, ukuthola umuntu ovuthiwe ngokocansi emvelweni akuyona into elula kososayensi bezinto eziphilayo. I-Arapaima ayikaze ibe uhlobo oluvame kakhulu, futhi manje seyande kakhulu.
Imvamisa itholakala ezindaweni ezingamaxhaphozi ezinokuqukethwe okuphansi komoya-mpilo emanzini. Ukuze iphile ezimweni ezinjalo, i-arapaima isungule okokusebenza okuphefumulayo okukhethekile okumvumela ukuthi aphefumule umoya-mpilo womoya.
Futhi ukuze iphile, idinga ukukhuphukela ebusweni bamanzi i-oxygen njalo ngemizuzu engama-20.
Ngaphezu kwalokho, i-piraruku amakhulu amaningi eminyaka yayiwumthombo oyinhloko wokudla kwezizwe ezihlala e-Amazon.
Kwakungenxa yokuthi wavukela phezulu emoyeni futhi wamchitha, abantu bazingela lo mzuzu, base bembulala ngosizo lwezingwegwe noma bambamba enetheni. Ukuqothulwa okunjalo kunciphise kakhulu inani labantu futhi kulibeka engcupheni yokubhujiswa.
Ukuphila emvelweni
I-Arapaima (Latin Arapaima gigas) yachazwa okokuqala ngo-1822. Ihlala ebangeni lonke le-Amazon nasemiseleni yayo.
Indawo ehlala kuyo incike esikhathini sonyaka. Ngesikhathi esomile, i-arapaima ifudukela emachibini nasemifuleni, futhi ngenkathi yezimvula, iye emahlathini agcwele amanzi. Imvamisa ihlala endaweni eyixhaphozi, lapho eye yajwayela ukuphefumula umoya-mpilo womoya, ukuyigwinya ingaphezulu.
Futhi emvelweni, ama-arapaima avuthiwe ngokocansi adla kakhulu izinhlanzi nezinyoni, kepha ama-juveniles awasuthiseki kakhulu futhi adla cishe yonke into - inhlanzi, izinambuzane, izibungu, izinambuzane ezingenamgogodla.
Incazelo
I-arapaima inomzimba omude nobekene onamaphiko amabili amancane we-pectoral. Umbala womzimba uluhlaza okotshani namabala ahlukahlukene, nezikali ezibomvu esiswini.
Unezikali ezinzima ngokwedlulele ezibukeka kakhulu njenge-carapace futhi kunzima kakhulu ukubhoboza.
Le ngenye yezinhlanzi ezinkulu zasemanzini angenasawoti, ikhula cishe ngama-60 cm e-aquarium futhi ihlala iminyaka engaba ngu-20.
Futhi emvelweni, ubude obumaphakathi bungu-200 cm, yize kukhona nabantu abakhulu. Kunemininingwane ku-arapaima 450 cm ubude, kepha isukela ekuqaleni kwekhulu leminyaka elidlule futhi ayibhalwanga.
Isisindo esiphezulu esiqinisekisiwe ngu-200 kg. Abancane bahlala nabazali babo ezinyangeni ezintathu zokuqala zokuphila futhi bafinyelela ekuvuthweni kuphela lapho beneminyaka emihlanu.
Kunzima kokuqukethwe
Ngaphandle kokuthi izinhlanzi azifuneki kangako, kepha ngenxa yobukhulu bayo nolaka, ukuyigcina emanzini asemakhaya akubonakali kungokoqobo.
Udinga cishe amalitha angu-4,000 amanzi ukuze azizwe ejwayelekile. Noma kunjalo, kuvame kakhulu emaphoyiseni nasemibukisweni ehlukahlukene.
Ukondla
Isilwane esidla kakhulu izinhlanzi, kodwa futhi sidla izinyoni, izinambuzane ezingenamgogodla namagundane. Kuyisici ukuthi bagxume baphume emanzini bese bethatha izilwane ezihleli emagatsheni ezihlahla.
Ekuthunjweni, zondla kuzo zonke izinhlobo zokudla okuphilayo - inhlanzi, amagundane nokudla okuhlukahlukene okwenziwe.
Ukondla e-zoo:
Ukungafani ngokocansi
Kunzima ukusho ukuthi owesilisa uyakhanya yini kunowesifazane ngesikhathi sokuzala.
Ukuzala
Owesifazane uvuthwa ngokocansi eneminyaka engu-5 nangobude bomzimba obungu-170 cm.
Ngokwemvelo, ama-arapaima azala ngesikhathi esomile, kusuka ngoFebhuwari kuya ku-Ephreli akha isidleke, futhi ngokuqala kwenkathi yemvula, amaqanda achanyuselwa futhi gazinga lisesimweni esihle sokukhula.
Ngokuvamile bamba isidleke phansi esihlabathini, lapho insikazi izalela khona amaqanda. Abazali bagada isidleke ngaso sonke isikhathi, futhi gazinga bahlala ngaphansi kwesivikelo sabo okungenani izinyanga ezintathu emva kokuzalwa.
