Mwa nsomba zambiri, pali zomwe zimatsata makolo awo kuyambira kale. Chimodzi mwa izi - arowana, nsomba, malinga ndi zotsalira zakale zomwe titha kudziwa kuti amakhala mu nthawi ya Jurassic.
Maonekedwe a Arowana
Poyamba arowana - madzi akumwa amtchire nsombaa banja la dzina lomwelo. Iyi ndi mitundu yayikulu kwambiri, m'chilengedwe imafikira kukula kwa masentimita 120-150. Mu aquarium, mitundu yosiyanasiyana imakula m'njira zosiyanasiyana, koma nthawi zonse osachepera theka la mita.
N'zochititsa chidwi kuti nsombayo imakula msanga, m'miyezi isanu ndi umodzi thupi lake limatalikirana ndi masentimita 20 mpaka 30. Kulemera kwake kwa nsombayo kumafika 6 kg, pafupifupi pafupifupi 4.5 kg. Thupi lake lili ngati riboni, ngati njoka, kapena thupi la chinjoka chopeka.
Imakanikizidwa kwambiri kuchokera mbali, imapangidwa ngati tsamba, nsonga yake yomwe ili mkamwa. Nsombazo zimatha kumeza nyama yaikulu, chifukwa pakamwa pake pamatseguka kwambiri. Antenna amakula pamlomo wapansi; posambira, amapita kutsogolo.
Nsomba ndi mtundu wakale, wakale womwe sukusintha ndipo ulibe mano. Zipsepse za pectoral ndizochepa, ndipo zipsepse zam'mbuyo ndi zam'mbuyo zimayambira pakati pa thupi ndikuphatikizika bwino mchira osalekana. "Kupalasa" uku kumathandiza kuti nsomba zizithamanga kwambiri.
Pobereka mitundu, zipsepsezi zimagawika, komabe zimayesetsa imodzi. Mtundu wa zipsepse za achinyamata nthawi zambiri umakhala wowala, umadetsa pakapita nthawi. Mamba pa arowana lolimba, lalikulu kwambiri. Mtundu umatha kusiyanasiyana kutengera mitunduyo. Mtundu wachilengedwe wosiyanasiyana, achinyamata amakhala ndi buluu.
Malo okhala Arowana
Arowana ndi mbadwa yaku South America, amakhala m'mabeseni amadzi amchere amitsinje monga Amazon, Oyapok, Essequibo. Adadziwitsidwa ku North America, ndipo amapezeka m'maiko ena aku United States.
Mitsinje ya South China, Vietnam ndi Burma kale inali malo amtundu wamtundu wotsika kwambiri wa arowana, koma tsopano, chifukwa cha kuwonongeka kwa nsomba, ili pafupi kutheratu, ndipo imapangidwa m'madzi ndi madamu. Mayiwe a Guyana ali ndi arowana wakuda komanso wowona. Mitundu yotchuka imafalikira kumwera chakum'mawa kwa Asia Asia arowana, amakhala kumeneko mumitsinje yabata.
Mumikhalidwe yachilengedwe, nsomba zimasankha malo odekha komwe kulibe mphamvu. Amasankha madera amphepete mwa nyanja, mitsinje ndi nyanja zotentha zotentha bwino: 25-30 C⁰. Mitsinje ikuluikulu ikasefukira, arowana amalowa ndikukhalabe m'nkhalango zowirira, m'madzi osaya. Zimatha kulekerera kufooka kochepa kwa mpweya m'madzi.
Chisamaliro cha Arowana ndi kukonza
Chifukwa arowana nsomba zazikulu, ndiye aquarium amafunikira chachikulu. Munthu wa pafupifupi masentimita 35 amafunika osachepera 250 malita amadzi. Mwambiri, kukula kwa aquarium kumakhala bwino.
Kusuntha kwabwino kwambiri ndi malita 800-1000. Iyenera kukhala yosachepera mita imodzi ndi theka kutalika ndi theka la mita. Ndikofunikira kukonzekeretsa aquarium ndi chivindikiro chowoneka bwino, chifukwa mwachilengedwe, ma arowan amalumpha m'madzi ndi 1.5-3 mita kuti agwire tizilombo kapena mbalame yaying'ono.
Kuunikira kwa aquarium sikuyenera kuyatsa mwadzidzidzi, koma pang'onopang'ono kumayaka kuti nsomba zisachite mantha. Kwa aquarium, arowans amalimbikitsa kusankha plexiglass, yomwe ndi yamphamvu kuposa yosavuta, ndipo chifukwa chake, ndiyotetezeka kusunga nsomba zazikulu komanso zamphamvu chonchi.
Kuti muyeretsedwe madzi, muyenera sefa yabwino, yamphamvu, muyenera kusefera nthaka ndikusintha kotala lamadzi sabata iliyonse. Kutentha ndikoyenera kwa nsomba izi, monga kuthengo: 25-30 C⁰, ndi kuuma kwa 8-12⁰ ndi acidity wa 6.5-7pH. Madzi amchere amatsutsana mu arowane, nsomba zimatha kudwala.
Sikoyenera kubzala mbewu mu aquarium ndi arowans, amatha kuchita popanda iwo. Koma, ngati muzigwiritsa ntchito, ndibwino kuti musankhe ndi mizu yolimba, limbikitsani zotengera zokhala ndi mbewu pansi, apo ayi nsomba ziziwakhadzula ndi kuwadya.
Mitundu yosiyanasiyana ya arowana imadya mosiyanasiyana. Mwachilengedwe, imagwira nsomba, tizilombo tomwe timauluka pamwamba pamadzi ndikuyandama pamwamba, nkhanu, amphibiya. Koma mukakhala ndi aquarium, mutha kumudyetsa nyama, nsomba zazing'ono, nkhanu, tizilombo touma komanso amoyo komanso chakudya chapadera.
Mutha kugwira ziwala, crickets, achule ndi tizilombo tina kuti tipeze nsomba, koma ndibwino kugula m'masitolo ogulitsa ziweto, chifukwa mwachilengedwe tizilombo tina titha kutenga matenda omwe amapatsidwa nsomba. Kuti mufulumizitse kukula, mutha kugwiritsa ntchito mtima wang'ombe, pomwe pamatulutsa mafuta omwe sangadye arowana.
Ziweto zimatha kutenga chakudya m'manja mwa eni ake, chifukwa zimawonetsa zanzeru, amazindikira omwe amawasamalira ndipo sawopa. Malinga ndi eni arowan, nsombazi ndizanzeru. Kuphatikiza pa luntha, Arowans amapatsidwanso kufunika mu Feng Shui - amakhulupirira kuti amabweretsa zabwino mu bizinesi.
Mitundu ya Arowana
Pakadali pano pali mitundu pafupifupi 200 ya nsombazi, zonse ndizosiyana, komanso zokongola kwambiri, monga momwe tingawonere chithunzi arowana... Tiyeni tikambirane mitundu yotchuka kwambiri.
Silver arowana kwawo koyamba kuchokera ku Mtsinje wa Amazon, nsomba yayikulu kwambiri mpaka kutalika kwa 90 sentimita mu ukapolo. Mwa mitundu iyi, mapiko a caudal ndi dorsal amaphatikizika kukhala ofanana. Mtundu wa masikelo ndi siliva. Zosiyanasiyana zotsika mtengo.
Pachithunzicho, nsomba zasiliva za arovan
Platinum Arowana ang'onoang'ono, amakula mpaka masentimita 40. Ndiwo okhawo arowan omwe ali ndi utoto wabwino kwambiri. M'mikhalidwe yam'madzi am'madzi, nsomba iyi idayamba kukhala ndi squint, yomwe tsopano ndi gawo la mitunduyi.
Pachithunzipa, nsomba ya arowana ya platinamu
Arowana Giardini kapena ngale, mpaka masentimita 90. Nsombazi zimachokera ku New Guinea ndi Australia. Mitundu yokongola imafanana ndi mitundu ya platinamu.
Mu chithunzi arovana giardini
Kubereka ndi kutalika kwa moyo
Mwachilengedwe, nsomba zimaswana ndi kusefukira kwamadzi, mu Disembala-Januware. Yaimuna imatolera mazira omwe atulutsa ndikuwasunga mkamwa mwake kwa masiku 40. Mphutsi zokhala ndi ma yolk sac sizitulutsidwanso kunja, ndipo pokhapokha ana akatha kudzidyera okha, bambo wachikondi amamasulidwa pantchito yake. Izi zimatenga pafupifupi miyezi iwiri.
Zimakhala zovuta kubzala nsombazi kunyumba, nthawi zambiri zimachitika ndi mabungwe akuluakulu, nazale "komwe amakhala" arowanas. Fry zomwe zakula kale zimaperekedwa mdziko lathu. Arowana amakhala nthawi yayitali kwambiri - zaka 8-12.
Mtengo wa Arowana ndikugwirizana ndi nsomba zina
Popeza nsombayo ndi yayikulu komanso yodya nyama, sizingakhale zomveka kuzisunga ndi nsomba zazing'ono, pokhapokha ngati zidakonzedwa kuti zizidyetsa arowane. Nsomba sizimakonda oimira mitundu yawo, ndipo zimamenya nkhondo nthawi zonse.
Ndibwino kuti muzisunga nokha, kapena, ngati thankiyo ndi yayikulu, muikemo nsomba zazikulu zomwe zimaposa kukula kwa arowana. Muthanso kuwonjezera ma astronotus ndi nsomba zina zamatchire, parrot fish, scalar. Koma, pankhaniyi, palibe chifukwa chomwe njala ya arowna ingaloledwe, chifukwa nthawi yomweyo ayamba kusaka aliyense yemwe angakwaniritse pakamwa pake.
Sikuti aliyense angakwanitse kugula arowan - amadziwika kuti ndi nsomba yotsika mtengo kwambiri ku aquarium. Mtengo wa Arowana mitundu yosiyanasiyana imasiyanasiyana kwambiri ndipo nthawi zonse imakhala yokwera kwambiri. Nsomba zitha kulipira ma ruble 30 mpaka 200,000.
