Magawo osinthika a nsombazi samamveka bwino chifukwa chakusowa kwa sayansi. Akatswiri a zachikhalidwe cha anthu amanena kuti oyambirira oyambirira a nsomba zamakono analipo m'mitsinje ya North America zaka 50 miliyoni zapitazo. Inali yaying'ono kukula ndipo imafanana ndi imvi m'maonekedwe ndi moyo. Chifukwa chakuti oimira banjali pakusintha amayenera kupulumuka nyengo zosiyanasiyana, amakhudzidwa kwambiri ndi kusintha kwa malo okhala.

Malinga ndi zojambula pamiyala, titha kunena kuti makolo akale amchere wamchere wamakono anali kale m'chigwa cha Pacific Ocean pafupifupi zaka 10 miliyoni zapitazo. Mitundu ina ya nsomba imakhala m'madzi akulu.

Mitundu yambiri ya salmon yatha. Chimodzi mwazinthu zodabwitsa kwambiri komanso zodabwitsa zomwe zatha ndi "saum-toothed saumoni". Amatchulidwa ndi kambuku wamphongo wamasamba chifukwa chakupezeka kwa zilombo zazitali, zosadziwika bwino za nsomba. Kutalika kwawo kunafika masentimita 5-6 mwa anthu akulu.

Nthawi yabwino kwambiri m'mbiri ndi kusinthika kwa nsomba ya chum idabwera zaka 2-3.5 miliyoni zapitazo. Inali nthawi imeneyi pomwe ma salmonid adagawika m'mitundu, iliyonse yomwe idakhala m'dera lokhalamo.

Yemwe akuyimira banja la salmon amakhala nthawi yayitali m'madzi am'nyanja. Pogwirizana ndi izi, ili ndi utoto wofanana ndi womwe umakhala kunyanja: siliva-buluu ndikutuluka. Kudera lakumbuyo, nsombayo imakhala ndi mdima wakuda, m'chigawo cham'mimba ndimowala. Mtunduwu umathandiza kuti nsombazi zisadziwike m'madzi komanso pansi. Chuma cha chum chimakhala ndi mawonekedwe ndi mawonekedwe angapo.

Zizindikiro zakunja:

• thupi lalikulu lazitali, zazitali;
• zolimba pang'ono, mbali zomata;
• Zipsepse za caudal ndi adipose zimasunthidwa pang'ono kumchira ndipo zimakhala ndi nthenga za 8 mpaka 11;
• mutuwo ndi waukulu motsutsana ndi thupi lalikulu ndipo umakhala ndi mawonekedwe a kondomu;
• pakamwa ndi yotakata, pali mano osakwanira pakamwa;
• kulibe mawanga amdima ndi mikwingwirima mkamwa;
• thupi liri ndi masikelo apakatikati;
• pali chimbudzi chachikulu cholimba chopanda mphako.

Chosangalatsa: Pa nthawi yobereka, mawonekedwe a thupi ndi mawonekedwe a nsombazi amasintha modabwitsa. Thupi limakulanso ndikukula kwambiri, mawonekedwe a hump kumbuyo. Nsagwada zimakulirakulira, mano amapindika ndikukhala okulirapo komanso otalikirapo. Mtundu umakhala wofiirira, wachikasu, wobiriwira kapena maolivi. Mikwingwirima yofiirira kapena yofiira imawoneka pakatikati pa thupi, yomwe imada nthawi.

Nsomba zina zimatha kukula kwambiri. Thupi la Dina limatha kufikira masentimita 60-80, ndipo kulemera kwake kumatha kupitilira makilogalamu 10.

Chosangalatsa: Malinga ndi zomwe boma limanena, kukula kwakukulu kwa nsomba ya chum kunali mita imodzi ndi theka, ndipo kulemera kwake kunali makilogalamu 16!

Nsomba zomwe zimapita kukaswana nthawi zambiri zimakhala ndi thupi lokwanira masentimita 50-65. Kukula kwa thupi kwa nsomba ya chum yachilimwe ndikocheperako kuposa kukula kwa nsomba yamchere yachisanu.

Kodi nsomba za chum zimakhala kuti?

Chithunzi: Chum saumoni ku Russia

Salmon wa chum amakhala moyo wake wonse m'matupi amadzi amchere pafupi ndi gombe. Malo okhalamo nsomba zamchere ndi nyanja ya Pacific. Nsombazi nthawi zambiri zimatchedwa nsomba ya anadomous chifukwa imakhala m'nyanja, ndipo imakonda kukasambira kukamwa kwa mitsinje. Ndikoyenera kudziwa kuti popanga nsomba za chum zimayesetsa kupeza pakamwa pa mitsinje yomwe idatulukirako mwachangu. Kusamba kumachitika m'mitsinje yamadzi amadzi ku Far East, mayiko aku Asia, North America kuchokera ku California mpaka Alaska.

Nsombazo zimasankha madzi ofunda a Pacific Ocean - malo otsetsereka a Kuro-Sivo ngati madera okhalamo komanso chakudya.

Madera akutali a chum saum:

• Nyanja ya Okhotsk;
• Nyanja ya Bering;
• Nyanja ya Japan.

Kuswana kumachitika pakamwa pamtsinje. Munthawi imeneyi, nsomba zimatha kupezeka m'mitsinje monga Lena, Kolyma, Indigirka, Yana, Penzhira, Poronaya, Okhota, ndi zina zambiri. Chum salmon ndi nsomba yopanda madzi. Anthu ambiri amakhala ozama osapitirira mamita 10. Nsomba zimakhala gawo lalikulu la moyo wawo posamuka chakudya. Nthawi imeneyi imatha kuyambira zaka 2.5 mpaka 10.

Ichthyologists anazindikira kuti mwa oimira onse a nsomba omwe amakhala m'madzi a Pacific Ocean, ndi nsomba ya chum yomwe ili ndi malo okhala kwambiri. M'madera ena a Russia, makamaka ku Kamchatka ndi Sakhalin, chum saum amakhala m'madzi opangira ziweto zopangira nsomba.

Kodi nsomba za chum zimadya chiyani?
