Okuqukethwe
Ulwazi oluwusizo mayelana nokudoba i-vendace
E-Russia, kunezinhlobo ezimbili: i-vendace yaseYurophu naseSiberia. Ngowomndeni we-whitefish. I-vendace yaseYurophu iwuhlobo lwechibi nomfula echibini le-whitefish, iSiberia iwuhlobo lomfula. IYurophu, njengomthetho, yakha amafomu okuhlala, amaSiberia - amafutha olwandle. E-vendace yaseYurophu, umehluko omkhulu wangaphandle ubhekwa njengezikali ezibucayi kakhulu, eziwa kalula. I-European ingakha amafomu amancane futhi, ngokuvamile, incane (i-Onega ripus ifika ku-1 kg); I-vendace yaseSiberia ifinyelela isisindo se-1.3 kg. Ukuba khona kwezinhlobo ezincane kunzima ukunquma, futhi kukhona umehluko wesifunda we-morphological.
Izindlela zokubamba i-vendace
I-Vendace ibanjwa egiyeni elintantayo, elingaphansi, kanye negiya lokujikijela lasebusika nelasehlobo kanye nokuyenga okume mpo.
Ukubamba i-vendace egiyeni lokuntanta
Izinhlanzi zibanjwa kude kakhulu nosebe futhi ekujuleni okukhulu. Izinhlanzi zihlala ezindaweni ezingaphansi kwamanzi. Ukuze udobe, ungasebenzisa kokubili i-float kanye "nembongolo egijimayo". Ukudoba, izinduku ezine "running rig" zifanelekile. Inhlanzi ayibhekwa njengenamahloni kakhulu, kodwa igiya eliqinile alinconywa.
Ukubamba i-vendace ngegiya lasebusika
Ukudoba kwe-vendace okudume kakhulu ukudoba eqhweni ebusika. Kulokhu, kusetshenziswa izinduku zokudoba ezinqenqemeni. Sebenzisa i-mormyshki noma izingwegwe nge-nozzle. Kudingeka ukudla. Ngenxa yalokhu, inyama eqoshiwe yama-mollusks, ama-bloodworms, izibungu nokunye kungakhonza.
Ukubamba i-vendace ku-mormyshka ehlobo
Ukudoba nge-nodding tackle, izinduku zempukane ezihlonyiswe ngokukhethekile ezinama-nods akhethekile zisetshenziswa. Ukudoba, ama-mormyshkas asebusika ajwayelekile afanelekile: i-pellet, intuthwane, neconsi. Kungcono ukusebenzisa amamodeli amnyama. Ama-nods nesisindo se-mormyshkas akhethiwe ngokuvumelana nezimo zokudoba.
Amahubo
I-bait izingcezu zenyama ye-mollusk, izibungu ezingenamgogodla, kuhlanganise ne-bloodworms, izikelemu, izinhlanzi zezinhlanzi. Lapho udoba ngama-baubles, kuyanconywa futhi ukutshala izingcezu zenyama.
Izindawo zokudoba kanye nezindawo zokuhlala
Le nhlanzi ihlala emanzini alo lonke i-Arctic Ocean. Esifundeni sasePechora, uhla lokusabalalisa lwe-vendace yaseYurophu naseSiberia luxubile. I-vendace yaseSiberia nayo itholakala eNyakatho Melika. Ngaphezu kwalokho, izinhlanzi zingatholakala kwezinye iziqhingi ezisenyakatho (Novosibirsk Islands, Kolguev). Emifuleni igcina izindawo ezijulile ezinomsinga obuthakathaka. Ukuziphatha kwezinhlanzi kufana nezinye izinhlanzi ezimhlophe. Emachibini, ihlala kude nogu, izikole zezinhlanzi zihamba zifuna ukuqoqwa kwe-zooplankton. Abantu abakhulu, emachibini, bahlala ekujuleni okukhulu, kwesinye isikhathi kufika ku-15 m.
Ukuzalela
Iba ngabantu abavuthiwe ngokocansi eminyakeni engu-3-4. Amafomu ane-anadromous avela emifuleni emanzini, phansi esihlabathini samatshe. Ukuzala kwenzeka ekwindla, kuye ngezimo zemvelo, kunganwebeka kuze kuqale ubusika. Kwamanye amachibi aseNyakatho Yurophu, amafomu ane-spring spawning ayaphawulwa. Izinhlanzi zingazalela ekujuleni okukhulu.
