Ukudoba i-Vobla: iphila kuphi, izoyibamba ngani kanye nendlela yokuyenga
Umqondo we-roach kubantu uvame ukuhlotshaniswa nezinhlanzi ezomisiwe, ngakho ngezinye izikhathi kukhona ukudideka ekunqumeni uhlobo lommeleli we-ichthyofauna. Lapho uthengiswa ngaphansi kwaleli gama ungathola izinhlobo ezihluke ngokuphelele, kufaka phakathi i-bream nezinye. Eqinisweni, i-vobla ayilona uhlobo oluhlukile lwabameleli be-ichthyofauna. Igama libhekisela kuhlobo lwe-anadromous noma i-semi-anadromous ye-roach eyaziwayo, inhlanzi ye-cyprinoid order.
I-Vobla yigama lendawo lesimo semvelo sale nhlanzi, esatshalaliswa engxenyeni engezansi yeVolga neCaspian. Ngezibonakaliso zangaphandle, izinhlanzi zifana kakhulu nohlobo lwamanzi ahlanzekile lwe-roach, kodwa zihluka ngomzimba ophakeme kancane, ubukhulu kanye nokuhluka okuncane kombala. Ubukhulu be-roach bungafinyelela ubude obungaphezu kuka-40 cm nesisindo esingaba ngu-2 kg. Lezi zinhlanzi zingena emifuleni kuphela ukuze zizalele, njengomthetho, aziphakamisi phezulu. Kukholelwa ukuthi i-Caspian vobla empeleni ayiphakamisi ngaphezu kweVolgograd. I-Caspian ibonakala ngemihlambi eminingana yama-roach ngokubhekisela ezindaweni ezihlukahlukene zokuhlala: iNyakatho yeCaspian, iTurkmen, i-Azerbaijani. Ngesikhathi sokugijima kwentwasahlobo, kunezinhlanzi ezinkulu ezibulalayo, zihlotshaniswa nezinguquko ezingeni lamanzi emfuleni nezimo zezulu. Ukugijima kwezinhlanzi ngaphambi kokuzalela emifuleni kuqala ngisho nangaphansi kweqhwa, ngakho ukudoba kungase kuhluke kakhulu.
Izindlela zokudoba i-Vobla
Izinhlanzi zibaluleke kakhulu kwezohwebo. Ososayensi bakhomba ukwehla nokuncipha kwenani labantu baseVobla vobla. Nokho, ukunyakaza okukhulu kwezinhlanzi entwasahlobo kudonsela inqwaba yabadobi abayizimfundamakhwela. Ukudoba ama-roach kuwumsebenzi ojabulisayo futhi oyinselele. Kulokhu, kusetshenziselwa ukulwa okuhlukahlukene: izintambo zokudoba eziphothayo, ezintantayo neziphansi, ukudoba izindiza, imishini yokukhipha ibanga elide esebenzisa izintambo zokwenziwa, izinti zokudoba zasebusika.
Ukudoba i-roach nge-float tackle
Izici zokusebenzisa i-float gear yokudoba ama-roach zincike ezimweni zokudoba kanye nolwazi lomdobi. Ukudoba ogwini lwe-roach, izinduku zemishini "eyisithulu" engu-5-6 m ubude zivame ukusetshenziswa. Izinduku zokufanisa zisetshenziselwa ukulingisa ibanga elide. Ukukhethwa kwemishini kuhluke kakhulu futhi kunqunyelwe izimo zokudoba, hhayi ngohlobo lwezinhlanzi. Njengakunoma yikuphi ukudoba okuntantayo, into ebaluleke kakhulu i-bait ne-bait efanele.
Ukudoba ama-roach ngegiya elingaphansi
I-Vobla iphendula kahle egiyeni elingezansi. Ukudoba ngezinduku ezingezansi, okuhlanganisa okokuphakelayo nesikhethi, kulula kakhulu kwabaningi, ngisho nabadobi abangenalwazi. Bavumela umdobi ukuthi ahambe kancane echibini, futhi ngenxa yamathuba okuphakela amaphuzu, ngokushesha aqoqe izinhlanzi endaweni ethile. Isiphakeli nesikhethi njengezinhlobo ezihlukene zemishini ziyehluka kuphela ngobude benduku. Isisekelo siwukuba khona kwesitsha se-bait-sinker (i-feeder) kanye namathiphu aguquguqukayo entongeni. Iziqongo ziyashintsha kuye ngezimo zokudoba kanye nesisindo se-feeder esetshenzisiwe. I-nozzle yokudoba ingaba yimuphi umbhobho, kokubili imvelaphi yemifino noma yezilwane, kanye nokunamathisela. Le ndlela yokudoba itholakala kuwo wonke umuntu. I-Tackle ayifuni izisekeli ezengeziwe kanye nezinto zokusebenza ezikhethekile. Lokhu kukuvumela ukuthi udobe cishe kunoma iyiphi imizimba yamanzi. Kuyafaneleka ukunaka ukukhethwa kwama-feeders ngesimo nosayizi, kanye nezingxube ze-bait. Lokhu kungenxa yezimo ze-reservoir (umfula, i-bay, njll.) kanye nezintandokazi zokudla zezinhlanzi zendawo.
Amahubo
Ukuze udobe phansi nasezintweni ezintantayo, kusetshenziswa imibhobho yendabuko: isilwane nemifino. Kusetshenziswa imibhobho, izikelemu, izimpethu, izikelemu zegazi, nezinhlamvu ezihlukahlukene. Kubaluleke kakhulu ukukhetha i-bait efanele, lapho izingxenye zezilwane zengezwa khona njengoba kudingeka. Ukudoba ngempukane kusebenzisa izicupho ezihlukahlukene zendabuko. Ngokuvamile, izimpukane eziphakathi nendawo zisetshenziselwa izingwegwe No. 14 - 18, zilingisa ukudla okujwayelekile kwe-roach: izinambuzane ezindizayo, kanye nezibungu zazo, ngaphezu kwalokho, ama-invertebrates angaphansi kwamanzi kanye nezibungu.
Izindawo zokudoba kanye nezindawo zokuhlala
I-Vobla iyi-anadromous, uhlobo olufana ne-anadromous ye-roach ehlala ogwini loLwandle lwe-Caspian. Njengoba sekushiwo, inemihlambi eminingana olwandle: North Caspian, Turkmen, Azerbaijani. Ingena emifuleni emikhulu ukuze izalele. Abantu abadume kakhulu yiVolga. Ingase ingene kweminye imifula yesifunda hhayi ngonyaka futhi ngamanani amancane.
Ukuzalela
Izinhlanzi ziqala ukuzala ngoFebhuwari. Ukunyakaza okukhulu ngaphambi nje kokuzala, okwenzeka ekupheleni kuka-March-April. Izinhlanzi zifakwe emikhonweni ehlukahlukene, iziteshi, i-yoriki. I-Vobla ivuthwa ngokocansi eminyakeni engu-3-4. Izalela izikhathi ezi-5-6 empilweni. Ukuzalela kwenzeka emanzini angashoni ezitshalweni, ngokuvamile ezikhukhuleni ezomayo, zingabhubhisi amaqanda kuphela kodwa nezinhlanzi ezizalayo. Ngesikhathi sokuzala, izinhlanzi ziyayeka ukudla, kodwa ngenxa yokuthi lesi sikhathi sinwetshiwe futhi asidluli ngesikhathi esisodwa, izinhlanzi ezisebenzayo zingase zibe semhlambini.
