I-Capelin, uyok iyinhlanzi eyaziwa kakhulu kubantu abaningi baseRussia, evame ukudayiswa ngokudayisa. Inhlanzi ingeyomndeni we-smelt. Imvelaphi yegama lesiRashiya livela ezilimini ze-Finno-Baltic. Ukuhunyushwa kwaleli gama izinhlanzi ezincane, umlomo wombhobho nokunye. Ama-Capelin ayizinhlanzi eziphakathi nendawo, ngokuvamile afinyelela ku-20 cm ubude futhi anesisindo esingama-50 g. Kodwa, futhi, ezinye izibonelo zingakhula zifike ku-25 cm. Ama-Capelin anomzimba omude onezikali ezincane. Ososayensi baphawula i-dimorphism ethile yobulili; ngesikhathi sokuzala, amaduna anezikali ezinoboya ezingxenyeni ezithile zomzimba. Izinhlanzi zihlala yonke indawo ezindaweni ezishisayo, uhlobo olukhulu. Kunezinhlobo eziningana ze-subspecies, umehluko omkhulu wawo indawo yokuhlala. Ngenxa yobukhulu nobukhulu bazo, izinhlanzi ngokuvamile ziwukudla okuyinhloko kwezinhlobo ezinkulu ezifana ne-cod, i-salmon nezinye. Ngokungafani nezinye izinhlanzi eziningi zomkhaya, iyinhlanzi yasolwandle kuphela. I-Capelin yizinhlanzi ze-pelargic zolwandle oluvulekile, ezisondela ogwini kuphela ngesikhathi sokuzala. I-Capelin idla i-zooplankton, lapho ifuna imihlambi eminingi ezulazula ezindaweni ezibandayo zolwandle olusenyakatho.
Izindlela zokudoba
Ezimweni eziningi, izinhlanzi zibanjwa kuphela ngesikhathi sokufuduka kokuzala. Ukudoba i-capelin kwenziwa ngamagiya ahlukahlukene anetha. Ekudobeni okungatheni eduze nogu, izinhlanzi zingaqoqwa ngezindlela ezifinyeleleka kalula, kuze kufike kumabhakede noma obhasikidi. Ngenxa yokutholakala kalula kwezinhlanzi ngesikhathi sokuzala, cishe bonke abadobi basebenzisa izindlela ezilula. Indlela elula kakhulu ukusebenzisa amanetha amakhulu okuhlalisa. Inhlanzi idliwa ithosiwe, ibhenyiwe, ngophaya nokunye. Izitsha ezimnandi kakhulu ezivela ku-capelin freshest. Inhloso ebaluleke kakhulu yokudoba okunjalo ukulungiswa kwe-bait ye-hook gear, kokubili ekudobeni kwe-amateur kanye nabadobi.
Izindawo zokudoba kanye nezindawo zokuhlala
Indawo ye-capelin yi-Arctic nezilwandle eziseduze. EPacific, izikole zezinhlanzi zifinyelela oLwandle lwaseJapan ogwini lwase-Asia kanye neBritish Columbia phesheya kwezwe laseMelika. E-Atlantic, emanzini aseNyakatho Melika, i-capelin ifinyelela e-Hudson Bay. Kuwo wonke ugu lwaseNyakatho ye-Atlantic yase-Eurasia kanye nengxenye ebalulekile yogu lwe-Arctic Ocean, le nhlanzi yaziwa ngezinga elikhulu noma elincane. Kuyo yonke indawo, i-capelin ibhekwa njengesiheho esihle kakhulu sokubamba izinhlanzi zasolwandle ezinkulu. Ngenxa yokutholakala kwamaketanga okuthengisa, i-capelin manje ivame ukusetshenziselwa ukubamba izinhlanzi zasemanzini ahlanzekile njenge-pike, i-walleye noma i-snakehead. Njengoba sekushiwo, izinhlanzi zichitha ingxenye enkulu yokuphila kwazo olwandle oluvulekile, endaweni ye-pelargic, zifuna ama-zooplankton accumulations. Ngesikhathi esifanayo, ukuba ukudla okuyinhloko kwezinhlobo eziningi zezinhlanzi zasenyakatho.
Ukuzalela
Njengoba kunikezwe usayizi wabo omncane, i-capelin ine-fecundity ephezulu - amaqanda ayizinkulungwane ezingu-40-60. Ukuzalela kwenzeka endaweni engaselugwini ezindaweni ezingaphansi kwamanzi ezingeni lokushisa elingu-2-30 C. Izindawo zokuzalela zitholakala ezindaweni ezisesihlabathini nasemabhange anokujula kwamanzi okungafika ku-150 m. I-Caviar iyanamathela, iphansi, njengokuncibilika okuningi. Ukuzalanisa kungokwesizini, kuphelela enkathini yasentwasahlobo-ehlobo, kodwa kungase kwehluke ngokwesifunda. Ngemva kokuzala, inani elikhulu lezinhlanzi liyafa. Izinhlanzi ezizalelayo zivame ukugezwa ogwini. Ngezikhathi ezinjalo, amakhilomitha amaningi amabhishi angagcwala i-capelin efile.
