Ndekupi uye sei kubata omul, ndezvipi zviredzo uye kubata kwakakodzera kubata hove
Omul inoreva semi-kuburikidza newhitefish. Omul yakakomberedzwa neareola yezvakavanzika, vanhu vazhinji vanotenda kuti hove iyi inogara muLake Baikal chete. Muchokwadi, maviri subspecies ehove iyi uye akati wandei mafomu ekugara anogara muRussia. Mukuwedzera, omul inowanikwawo muNorth America. Iyo yakakura subspecies ndiyo Arctic omul, uremu hwayo hunogona kusvika 5 kg. Iyo Baikal omul idiki, asi pane zviitiko zvekubata vanhu vanorema anenge 7 kg. Arctic omul inogara nzvimbo yekuchamhembe kwehove dzose chena. Omul inoonekwa semhando inononoka kukura, pazera remakore manomwe ine saizi ye7-300 gramu.
Nzira dzekubata omul
Omul anobatwa pamagiya akasiyana, asi vane chinhu chimwe chete chavanofanana - chirauro. Omul inodyisa, sehove zhinji chena, pane invertebrates nehove diki. Vabati vehove vazhinji vanoshandisa tambo dzekugadzira dzakakura zvakafanana nechikafu chikuru. "Matanda ekukanda marefu" anowedzera kuredza kureba, iyo yakakosha pamiviri mikuru yemvura, saka inofarirwa newhitefish anglers. Kubata omul pazvirukwa zvekuruka, semaspiner, zvinogoneka, asi kuredza kwakadaro kunenge kusina basa. Kunyanya kunakidza uye kuwedzera omul hove kunoitika munguva yechando. Magiya mazhinji uye nzira dzekuredza ndedzekutanga.
Kubata omul pagiya rechando
Munguva yechando, iyo inonyanya kufarirwa yekubata omul inoitwa paLake Baikal. Chikamu chikuru chechirauro chinoiswa mugomba, icho chinokwezva mapoka e omul. Amphipods, iyo vabati vehove vanodana "bormash", inoshanda sechikafu chekuwedzera. Omul, mudhamu, kazhinji anogara pakadzika dzika, asi zvikamu zvechirauro zvinoita kuti ikwire pedyo nemakomba. Mubati wehove anocherekedza mwero apo omul yakamira nepaburi uye nokudaro inodzora kudzika kwetambo. Nokudaro, nzira iyi yekubata hove inonzi "peep". Tsvimbo dzehove, chokwadi, mareel ane huwandu hukuru hwetambo yekuredza, pane akati wandei akasungirirwa kune leashes. Pakupera kwemutsara, sink-shaped sinker inosungirirwa, ine zvishwe zviviri, pamagumo echipiri iyo tambo ine chitarisiko chemberi inobatanidzwawo. Tackle inofanirwa kuridzwa. Kubata hove kunoda humwe unyanzvi, nokuti nyuchi dzakarukwa pazvikorekedzo pasina ndebvu. Iyo by-catch inogonawo kusanganisira greylings.
Kubata omul pakuruka nekuyangarara giya
Kuredza omul muzhizha kunoonekwa sekwakanyanya kuoma, asi varedzi venzvimbo havasati vabudirira. Pakubata hove kubva kumahombekombe, giya rakasiyana-siyana "yekukanda kure-kure", matanda anoyangarara, "zvikepe" anoshandiswa. Kuwedzera kubudirira kunogona kunzi kubata hove kubva kuzvikepe. Omul dzimwe nguva anobatwa padiki ma spinners, asi akasiyana matipi ndiwo akanakisa mabheti. Izvo zvinogara zvichikodzera kuve nekupihwa kwematipi uye nhunzi, kunyanya kana iri nyaya yegrey kurumwa. Hove iyi inoruma zvakanyanya uye inogona kubvarura chirauro.
Zviredzo
Chaizvoizvo, omuls anodya mhuka dzakasiyana-siyana dzisina vertebrate dziri mumvura, iyo inonzi. zooplankton. Nzira dzekubata hove uye chirauro zvinoenderana neizvi. PaBaikal, machira emhando dzakasiyana siyana tsvuku anoonekwa seanonyanya kufarirwa. Sekureva kwevamwe varedzi, misanganiswa yekaroti neyeorenji inonyanya kukodzera arctic omul. Pakubata hove, maspinner epakati anosarudzwa, nepo zvichifanira kurangarirwa kuti makanda anofanirwa kuitwa kure uye chirauro chinofanira kudzika.
Nzvimbo dzekuredza uye dzekugara
Iyo Arctic omul yekudyisa haishandisi chete nzvimbo dziri padyo nemuromo wenzizi, asiwo inoenda kure mugungwa. Panguva imwecheteyo, inogona kugara mumvura ine munyu wakanyanya. Inodyawo crustaceans nehove duku. Nzvimbo yekugovera iri mukati mepakati pakati peMezen River bheseni pamwe chete negungwa rose reArctic kusvika kunzizi dzeNorth America muKornation Bay. Baikal omul inogara muBaikal chete, uye inoberekera mumigero yedhamu. Panguva imwecheteyo, mapoka akasiyana eBaikal omul anogona kusiyana munzvimbo dzekugara, mudhamu, uye panguva yekubereka.
Kubereka
Iyo omul inova yakakura pabonde pazera remakore 5-8. The Arctic subspecies inogara ichikura gare gare kupfuura yeBaikal. Arctic omuls inokwira kunzizi kuti ibereke zvakanyanya, kusvika 1,5 zviuru zvemakiromita. Haidyi panguva yekubereka. Kubereka pakati pematsutso. Mhuka inobereka inomiririrwa nevanhu vane makore 6-13, kubereka hakuitike gore negore. Mukadzi anobereka ka2-3 muhupenyu hwake. Baikal omul marvae anokunguruka mudhamu muchirimo, kwaanokura.
