Capelin, uyok ndi nsomba yodziwika bwino kwa anthu ambiri aku Russia, yomwe nthawi zambiri imagulitsidwa m'masitolo. Nsombazo ndi za banja la smelt. Chiyambi cha dzina lachi Russia chimachokera ku zilankhulo za Finno-Baltic. Kumasulira kwa mawuwa ndi nsomba zazing'ono, mphuno ndi zina zotero. Capelins ndi nsomba zapakatikati, nthawi zambiri mpaka 20 cm kutalika ndi kulemera pafupifupi 50 g. Koma, komanso, zitsanzo zina zimatha kukula mpaka 25 cm. Capelins ali ndi thupi lalitali lokhala ndi mamba ang'onoang'ono. Asayansi amaona dimorphism ina ya kugonana; pa nthawi yoberekera, amuna amakhala ndi mamba okhala ndi ubweya waubweya pazigawo zina za thupi. Nsomba zimakhala paliponse m'mphepete mwa nyanja, mtundu waukulu kwambiri. Pali ma subspecies angapo, kusiyana kwakukulu komwe kumakhala malo. Chifukwa cha kuchuluka kwake komanso kukula kwake, nsomba nthawi zambiri zimakhala chakudya chachikulu chamitundu yayikulu monga cod, salimoni ndi zina. Mosiyana ndi nsomba zina zambiri za m’banja, iyo ndi nsomba ya m’madzi basi. Capelin ndi nsomba za pelargic za m'nyanja yotseguka, zomwe zimayandikira m'mphepete mwa nyanja panthawi yobereketsa. Capelin amadya zooplankton, pofufuza zomwe nkhosa zambiri zimayendayenda m'madera ozizira a nyanja ya kumpoto.
Njira zophera nsomba
Nthawi zambiri, nsomba zimagwidwa pokhapokha pamene zisamukasamuka. Usodzi wa capelin umachitika ndi zida zosiyanasiyana zaukonde. Mu usodzi wachinyamata pafupi ndi gombe, nsomba zimatha kusonkhanitsidwa m'njira zofikirika, mpaka zidebe kapena madengu. Chifukwa chosavuta kupeza nsomba pa nthawi yoberekera, pafupifupi onse opha nsomba amagwiritsa ntchito njira zosavuta. Njira yabwino kwambiri ndiyo kugwiritsa ntchito maukonde akuluakulu otera. Nsomba zimadyedwa zokazinga, kusuta, mu pie ndi zina zotero. Zakudya zokoma kwambiri kuchokera ku capelin yatsopano kwambiri. Cholinga chofunikira kwambiri cha usodzi wotero ndikukonzekera nyambo ya zida za mbedza, popha nsomba zamasewera komanso asodzi.
Malo ausodzi ndi malo okhala
Malo okhala ku capelin ndi Arctic ndi nyanja zoyandikana nazo. Ku Pacific, masukulu a nsomba amafika ku Nyanja ya Japan pagombe la Asia ndi British Columbia kumtunda waku America. Ku Atlantic, ku North America madzi, capelin amafika ku Hudson Bay. M'mphepete mwa nyanja yonse ya kumpoto kwa Atlantic ku Eurasia ndi mbali yaikulu ya gombe la Arctic Ocean, nsombayi imadziwika kwambiri kapena yochepa. Kulikonse, capelin imatengedwa ngati nyambo yabwino kwambiri yopha nsomba zazikulu zam'madzi. Chifukwa cha kupezeka kwa maunyolo ogulitsa, capelin tsopano imagwiritsidwa ntchito nthawi zambiri kugwira nsomba zam'madzi monga pike, walleye kapena snakehead. Monga tanenera kale, nsomba zimathera nthawi yambiri ya moyo wawo panyanja, m'dera la pelargic, kufunafuna zooplankton. Panthawi imodzimodziyo, kukhala chakudya chachikulu cha mitundu yambiri ya nsomba zakumpoto.
Kuswana
Chifukwa cha kukula kwawo kochepa, capelin ali ndi mphamvu zambiri - mazira 40-60 zikwi. Kubereketsa kumachitika m'mphepete mwa nyanja m'munsi mwa madzi pa kutentha kwa 2-30 C. Malo obereketsa amakhala pamtunda wa mchenga ndi magombe okhala ndi madzi akuya mpaka 150 m. Caviar ndi yomata, pansi, monga fungo lambiri. Kubereketsa kumachitika m'nyengo yachilimwe, nthawi yachilimwe-chilimwe, koma imatha kusiyana m'madera. Pambuyo pa kuswana, nsomba zambiri zimafa. Nsomba zoswana nthawi zambiri zimasambitsidwa kumtunda. Panthawi ngati imeneyi, magombe ambiri amatha kukhala ndi capelin wakufa.
