Saika ndi nsomba ya pelagic yamtundu wa cod, yomwe ndi nsomba yosodza ndipo imakonda kutentha kwamadzi ochepa. Kutentha kwapanyanja ndi nyanja kukakwera kufika madigiri asanu pamwamba pa zero, sizingatheke kukumana ndi cod.
Kufotokozera kwa makeke
Saika, ndiyonso polar cod, ndiye mtundu wokhawo wamtundu umodzi wokha wa saikas. Arctic, madzi ozizira, nsomba za cryopelagian, ndizomwe zimafanana ndi cod. Thupi lake limafanana kwambiri ndi cod, koma ndizosatheka kuwasokoneza, chifukwa codyo ndi yaying'ono kwambiri. Amakhala m'chigawo cha Arctic, komanso m'nyanja zamchere ndi mitsinje yakumpoto.
Maonekedwe
Imodzi mwa nsomba zazing'ono kwambiri m'banja la cod... Kutalika kwa thupi kumakhala masentimita makumi awiri ndi asanu mpaka makumi atatu. Kutalika komwe nsomba imafikira ndi masentimita makumi anayi ndi asanu. Imalemera zosaposa magalamu mazana awiri ndi makumi asanu. Thupi lolololalo limapapatizidwa kwambiri pafupi ndi mchira. Mtunda wautali pakati pa dorsal ndi anal fin. Mbalame yotchedwa caudal fin ili ndi notch yakuya, ndipo the finral fin ili ndi cheza chowoneka bwino.
Mutu si waukulu molingana. Maso a cod ya Arctic amatambasulidwa, m'malo mwake ndi akulu komanso akulu m'mimba mwake kuposa kutalika kwa tsinde la mchira. Ili ndi nsagwada zakumunsi zotuluka ndi ndevu zowonda kumapeto, zomwe sizimawoneka nthawi zonse. Kumbuyo ndi kumutu kumakhala kofiirira. Mbali ndi mimba yake ndi yaimvi ndi utoto wachikaso, nthawi zina utoto wofiirira umapezeka. Thupi loonda komanso lalitali limathandiza nsomba kusambira msanga. Kuthwanima kuchokera mdima pamwamba mpaka siliva pansi, utoto umapulumutsa kwa adani omwe amagwiritsa ntchito cod ngati chakudya.
Khalidwe ndi moyo
Saika ndi nsomba yophunzirira, chifukwa chake imasunthira molunjika. M'mawa ndi madzulo imamira pafupi ndi pansi, ndipo masana ndi usiku imakhala m'malo onse amadzi. Nsomba yosazizira kwambiri imakhala pafupi ndi madzi am'nyanja, pafupi ndi madzi oundana. Amakonda kutentha kwa madzi pafupi ndi 0, kapena ndi zoyipa.
Ndizosangalatsa! Kutentha kotsika (pafupifupi madigiri zero) kumathandizira njinga kupirira kupezeka kwa zoletsa kuwuma zachilengedwe mthupi lake. Ndi glycoprotein yapadera yomwe imalepheretsa kuzizira.
M'dzinja, nkhokwe ya Arctic imadziunjikira m'magulu akulu, mosiyana ndi chilimwe, ndikusambira kupita kumtunda. Amakhala m'mitsinje yam'mitsinje ndi m'mphepete mwa nyanja.
Cike amakhala nthawi yayitali bwanji
Saika amadziwika kuti ndi nsomba yayitali. Pafupipafupi, nsomba imakhala zaka zisanu. Kutchire, kutalika kwanthawi yayitali ya cod ya Arctic sikupitilira zaka zisanu ndi ziwiri. Kwa madera akumpoto, kutalika kwa nthawi yayitali.
Malo okhala, malo okhala
Nsomba zaku Arctic zimapezeka munyanja iliyonse yomwe ili gawo la Arctic Ocean... Amapezeka pansi pa madzi oundana oyandama komanso m'madzi am'mbali mwa nyanja. Cod siyimira kutsika kosakwana mamita mazana asanu ndi anayi. Amasambira kumpoto mpaka madigiri eyite-faifi kumpoto. Ma saika ambiri amakhala mu Nyanja ya Kara, kum'mawa kwa Novaya Zemlya, ku Pyasinsky ndi ku Yenisei.
Zakudya za Saika
Nsombazi zimadya phytoplankton, zooplankton, kakang'ono kansomba kakang'ono ka euphause komanso mwachangu nsomba monga gerbil ndi smelt.
Kubereka ndi ana
Nthawi yotha msinkhu mu cod ya Arctic imayamba ali ndi zaka zitatu mpaka zinayi, ndipo kutalika kwa thupi kumafika masentimita khumi ndi asanu ndi anayi mphambu makumi awiri. M'dzinja ndi nthawi yozizira, nsomba zimayamba kutuluka. Caviar yawo imagonjetsedwa ndi chisanu ndipo imasambira bwino, chifukwa chake kutentha kotsika kwamadzi sikofunikira pakuwonekera kwa ana. Munthawi imeneyi, amasambira kupita kumtunda ndipo samadya chilichonse.
Ndizosangalatsa!Nsomba iliyonse imabala zipatso kuchokera kumazira zikwi zisanu ndi ziwiri mpaka makumi asanu. Kenako nsomba za ku Arctic zimasambira kubwerera m'nyanja, ndipo mazirawo amanyamulidwa pompano kutali ndi komwe amaponyedwako. Kwa miyezi inayi imangoyenda ndikukula, ndipo mwachangu kumawonekera kumapeto kwa masika.
Amakula msanga, ali ndi zaka zitatu, kutalika kwa thupi kumafika masentimita khumi ndi asanu ndi awiri. Chaka chilichonse cod imawonjezera masentimita awiri kapena atatu kutalika. Amadyetsa koyamba pazomera zazing'ono zomwe zimakhala munyanja ndi m'nyanja. Akamakula, mwachangu amayamba kusaka nsomba zazing'ono kwambiri. Nsomba zotere zimatulukira kamodzi m'moyo.
Adani achilengedwe
Saika ndi chakudya chamtengo wapatali kwa anthu okhala munyanja, komanso m'mphepete mwa nyanja. Ankhandwe akum'mwera, zimbalangondo zakumtunda, zisindikizo, anangumi a beluga, narwhal, mbalame zodya nyama ndi nsomba zimadya pa cod ya Arctic. Kwa ambiri a iwo, ndiwo nyama yomwe amawakonda kwambiri. Anthu amasaka cod ya Arctic chaka chonse, kuyambira nthawi yophukira.
Chiwerengero cha anthu komanso mtundu wa mitunduyi
Kuchuluka kwa nsombazi nthawi zonse sikukhazikika ndipo kumasinthasintha.... Pali nthawi zina yomwe imadzikundikira m'gulu lalikulu. Mwa mitundu zana, pali oimira osiyanasiyana, omwe amasiyana mosiyana wina ndi mzake.
Mitundu yomwe imadya plankton ndi yocheperako poyerekeza ndi yomwe imadya zamoyo zazikulu. Woyimira yaying'ono kwambiri ndi gadikul yakuya panyanja, kutalika kwake sikupitilira masentimita khumi ndi asanu. Cod ya Molva ndi Atlantic ndiimodzi mwazikulu kwambiri mpaka kutalika kwake mita 1.8.
Mtengo wamalonda
Saika si nsomba zamalonda zamtengo wapatali... Nyama yake yoyera yoyera imakhala ndi mapuloteni ambiri, koma ndi owuma komanso amadzi, nthawi zina amakhala ndi kulawa kowawa. Sichosiyana ndi kukoma kwake, chifukwa chake chikufunika kukonzedwa. Nsombazi zimaumitsidwa ndi kusutidwa, zomwe zimagwiritsidwa ntchito pazakudya zamzitini. Abwino kupanga nsomba chakudya ndi nyama. Nyama yake ili ndi mafupa ambiri ndi zinyalala.
Ndizosangalatsa!M'dzinja, cod ya Arctic imayenda kumadzulo ndi kumwera. Kuyambira Okutobala mpaka Marichi, nsomba zimayamba "zhor", panthawiyi zimawedza.
Nyama ya Saika, ngakhale siyabwino kwambiri, imakhala yopatsa thanzi.
Zidzakhalanso zosangalatsa:
- Kuphulika kwa nsomba
- Nsomba zagolide
- Nsomba zaimvi
- Nsomba zapinki za pinki
Lili ndi omega-3 acids, mapuloteni ambiri ndi mchere, ndipo ili ndi ayodini wambiri. Nyama ya nsombayi imakhala ndi ma calories ochepa, chifukwa chake imawonedwa ngati yazakudya, komanso ndiyosavuta kukumba. Palibe zotsutsana pakugwiritsa ntchito kork, chokhacho ndichosalolera kwa mankhwalawa.
