Kodi nsomba zochititsa chidwi za phokoso ndi ziti?

Pakalipano, m'magulu a madzi a m'midzi a anthu ambiri omwe kale anali asodzi a CIS amagwira zamoyo zochepa, koma zodabwitsa kwambiri. Awa ndiwo nsomba za phokoso, zosiyana ndi maonekedwe ndi zizoloŵezi zodabwitsa.

Mwinamwake mumadziwa momwe zimakhalira mwamphamvu kubwezera njerwayo? Timayesetsa kukuutsimikizirani kuti wosusukayo akuwongolera bwino. Kwa oyamba kumene, ndondomeko yomasulira imachititsa mantha ndi mantha: nsomba yaing'ono (kuyambira 14 mpaka 25 cm pazitali) imadziwika ndi nsagwada yaikulu ndi toothy yomwe imawoneka ngati chikhalidwe mu filimu yowopsya!

Odziŵa nsomba, akugwedezeka ndi manja awo, ndipo amakhalabe chinthu chokhumudwa chogwira "muck" wotero. Mmawu, nsomba ndizogwedeza - zomwe ndi nyama!

Sayansi yaing'ono yochepa: m'Chilatini nsomba iyi imatchedwa Perccottus glenni, ili m'gulu la ziphuphu ndipo imaphatikizidwa mu gawo la ng'ombe zamphongo, zomwe zimatengedwa m'banja losiyana - mutu. Inde, ngakhale kuti ankagwirizana kwambiri ndi nsomba, nsomba za Ratan zinasiyanitsidwa. Ndipo zikanakhala bwanji izi: achibale a zowonongeka kwambiri za madzi athu amawoneka ngati ng'ombe zamphongo ...

Mukamayang'ana pafupi ndi Rotana, mumvetsetsa chifukwa chake chimatchedwa "bullet". Mtundu suli mwangozi - nsombazi zimakhala mumtambo wakuda, wamatope, momwe ngakhale ngakhale mapiko a olimba samagwirizana.

Komabe, zonse zimadalira apa onse pa nthawi ndi pamalo omwe akugwira. Ngati dziwe liri lalikulu mokwanira ndi loyera, nsomba za phokoso nthawi zambiri zimakhala zowala. Komanso, izi sizinangokhala zazikulu, koma pafupifupi zimakhala njira zowonongeka, nthawi zina ngakhale zowononga mitundu yonse ya achibale awo.

Mukagwira chipolopolo champhongo pa nthawi ya mating, mudzawona kuti nkhope yonse ya thupi lake ili ndi malo owala a lalanje. Kufanana ndi smut wonyezimira kumakhala kosatsutsika konse!

Rotan inachokera ku Far East, ikugwiritsanso ntchito chitsanzo china cha kulembetsa zinthu komanso kupusa kwaumunthu. Pokhala atakhala yekhayo madzi ena ndi nyanja, nthawi zambiri ankakhala ndi mitundu yambiri ya nsomba zamtengo wapatali.

M'dziko lakwawo, limakhala m'madzi aang'ono okha komanso osasangalatsa. Mu Amur omwewo ali ndi mpikisano wambiri, ndipo ngakhale makoswe akuluakulu adzalowedwa opanda tsatanetsatane ndi ambiri okhala m'madzi amenewo.

M'madera a ku Ulaya a dzikoli, mitundu yodabwitsayi inayambira kumayambiriro kwa zaka za zana la 20. Maulendo ake ogonjetsa adayamba kuchokera kumabwato a St. Petersburg, pomwe mu 1912 chitsanzo ichi chinatulutsidwa ndi aquarist. Ngakhalenso asanakhale Revolution, rotan mwamsanga inakhazikika pafupifupi mabwawa onse pafupi ndi Gulf of Finland.

Ngakhale izi, m'zaka zimenezo mpaka kufika ku likulu, nsomba sizikanatha. Koma kale mu 1948, zowola zowononga zinabweretsedwa ku Moscow ndi zofanana, zomwe zinagulitsidwa m'magulu akuluakulu pa "mbalame". Malo okongola a ku Moscow omwe ankayenera kulawa, ndipo pofika zaka za m'ma 50 akhoza kupezeka m'mphepete mwa msewu ngakhale mumsewu wa pamsewu.

Mwamwayi, mu mitsinje mitundu iyi ikukula bwino: madzi otsika otsika ndi omwe amachititsa kuti awononge, ndipo pali ochita mpikisano ambiri. Pakalipano, amagawidwa pafupifupi kudera lonse la Ulaya: ngakhale ku Czech Republic, asodzi asanalankhule kale, akugwedezeka. Kum'mwera, dziko la Uzbekistan likubwera kale. Zikuganiza kuti kumayambiriro kwa chaka cha 2050 chidzafika pamtunda wa Volga.

Zithunzi zomwe mwasankha zidzalola kuti mudziwe zomwe nsomba za makoswe zimawoneka. Chabwino, ndizodabwitsa bwanji, tinakuuzani!
