Okuqukethwe
Konke mayelana ne-sterlet nokuyidoba
Izinhlobo ze-sturgeon zifakwe ohlwini lwe-Red Book (Uhlu Olubomvu lwe-IUCN-96, I-Appendix 2 ye-CITES) futhi iyingxenye yesigaba sokuqala sokungavamile - imiphakathi ngayinye yezinhlobo ezisabalele ezisengozini.
Sicela uqaphele ukuthi izinhlanzi ze-sturgeon zingabanjwa kuphela emanzini akhokhelwayo.
Ummeleli omncane womndeni we-sturgeon. Naphezu kweqiniso lokuthi kukhona amacala aziwayo okubamba ama-specimens angaba ngu-16 kg, phakathi kwabanye abamele uhlobo lwe-sturgeon, i-sterlet ingabhekwa njengenhlanzi encane (ikakhulukazi ama-specimens angu-1-2 kg afika, ngezinye izikhathi aze afike ku-6 kg). Ubude bezinhlanzi bufinyelela ku-1,25 m. Ihluke kwezinye izinhlobo ze-sturgeon yaseRussia ngenani elikhulu "lezimbungulu" ezingemuva. Abanye ososayensi baphikisa ngokuthi kunomehluko wobulili ekukhethweni kokudla ku-sterlet. Abantu besilisa banamathela ekondleni izilwane ezingenamgogodla ngokushesha okukhulu kukholomu yamanzi, kanti abesifazane babonakala ngokudla okuseduze naphansi ezingxenyeni ezipholile zechibi. Ukuba khona okuphansi nakho kuyisici sabantu abakhulu babo bobubili ubulili.
Izindlela zokudoba i-Sterlet
Ukudoba i-Sterlet ngezindlela eziningi kufana nokubamba amanye ama-sturgeon, alungiselwe usayizi. Ngokuvamile iba yi-by-catch lapho udobela ezinye izinhlanzi. Indawo ephansi yomlomo ibonisa indlela yabo yokudla. Ukudoba ukuzijabulisa emanzini amaningi emvelo kunqatshelwe noma kulawulwa ngokuqinile. Kuyinto yokuzalanisa ezindaweni zokugcina amanzi. Kuyafaneleka ukuxoxisana nomnikazi wechibi kusengaphambili ngezimo lapho ukudoba kwenzekani. Lapho udoba ngesisekelo sokubamba-futhi-ukukhululwa, cishe kuzodingeka usebenzise izingwegwe ngaphandle kwama-barbs. Ukudoba i-Sterlet kungenzeka ngosizo lwegiya elingaphansi kanye ne-float, inqobo nje uma i-bait itholakala ngaphansi kwe-reservoir. I-down tackle ingaba lula kakhulu, ngokuvamile isebenzisa izinduku zokuphotha. Emfuleni, i-sterlet igcina umsinga. Abantu bendawo abahlala osebeni lwemifula ecebile nge-sterlet bathandwa "ngama-rubber bands". Ebusika, le nhlanzi ayisebenzi, futhi ibanjwa ngokungahleliwe.
Ukubamba i-sterlet ngegiya elingezansi
Ngaphambi kokuya endaweni lapho i-sturgeon itholakala khona, hlola imithetho yokudoba le nhlanzi. Ukudoba emapulazini ezinhlanzi kulawulwa ngumnikazi. Ezimweni eziningi, ukusetshenziswa kwanoma yiziphi izinti zokudoba ezingezansi kanye nokudla okulula kuvunyelwe. Ngaphambi kokudoba, hlola usayizi wama-trophies okungenzeka kanye ne-bait enconywayo ukuze wazi amandla omugqa odingekayo namasayizi we-hook. Isisetshenziswa esibalulekile lapho ubamba i-sturgeon kufanele kube inetha elikhulu lokufika. Ukudoba okuphakelayo kanye nesikhethi kulula kakhulu kwabaningi, ngisho nabadobi abangenalwazi. Bavumela umdobi ukuthi anyakaze echibini, futhi ngenxa yamathuba okuphakela amabala, ngokushesha “baqoqa” izinhlanzi endaweni ethile. Isiphakeli nesikhethi, njengezinhlobo ezihlukene zemishini, okwamanje zihluka 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. Izikelemu ezihlukahlukene, inyama yegobolondo nokunye kungasebenza njengombhobho wokudoba.
Le ndlela yokudoba itholakala kuwo wonke umuntu. I-Tackle ayifuni izisekeli ezengeziwe kanye nezinto zokusebenza ezikhethekile. Ungakwazi ukudoba cishe noma yimuphi umzimba wamanzi. Naka ukukhethwa kwama-feeders ngesimo nosayizi, kanye nezingxube ze-bait. Lokhu kungenxa yezimo ze-reservoir (umfula, ichibi, njll.) kanye nezintandokazi zokudla zezinhlanzi zendawo.
Ukubamba i-sterlet egiyeni lokuntanta
Izinsimbi zokuntanta zokudoba i-sterlet zilula. Kungcono ukusebenzisa izinduku nge "rig egijima". Ngosizo lwe-reel, kulula kakhulu ukudonsa ama-specimens amakhulu. Imishini kanye nemigqa yokudoba ingaba nezakhiwo zamandla ezikhulayo. I-tackle kufanele ilungiswe ukuze umlomo wombhobho ube ngezansi. Amaqhinga ajwayelekile okudoba afana nokudoba ngezinduku ezingaphansi. Uma kungekho ukulunywa isikhathi eside, udinga ukushintsha indawo yokudoba noma ushintshe i-nozzle. Kufanele ubuze abadobi abanolwazi noma abahleli bokudoba mayelana nokudla kwezinhlanzi zasendaweni.
Amahubo
I-sterlet isabela kalula ezindleleni ezihlukahlukene zemvelaphi yezilwane: izibungu, izibungu nezinye izibungu ezingenamgogodla. Enye yezinketho eziyinhloko zokudla inyama ye-shellfish. Izinhlanzi, njengamanye ama-sturgeon, zisabela kahle ezidlelweni ezinephunga elimnandi.
Izindawo zokudoba kanye nezindawo zokuhlala
Izinhlanzi zisakazwa kabanzi. Indawo yokusabalalisa ithumba izilwandle zeBlack, Azov kanye neCaspian Seas, i-Arctic Ocean. Okukhethekile kwe-sterlet ukuthi ikhetha amachibi agelezayo. Naphezu kokusatshalaliswa kwayo okubanzi, ibhekwa njengenhlanzi engavamile futhi evikelekile ezindaweni eziningi. I-sterlet ingaphansi kwempango ezingelayo ngabazingeli, kuyilapho ingakubekezeleli ukungcoliswa kwedamu ngamanzi angcolile avela kumabhizinisi nezolimo. Futhi, isibalo sama-sterlet sisesimweni esidabukisayo emifuleni lapho kunenani elikhulu lezakhiwo ezisebenza ngaphansi kwamanzi noma izimo zezindawo zokuhlala zishintshile. Ukudoba kulawulwa ngamalayisensi. Abadobi abanolwazi bakholelwa ukuthi i-sterlet esebenzayo ikhetha ukuhlala ezindaweni ezinomsinga omaphakathi kanye nephansi eliyisicaba. Ngesikhathi se-zhora, izinhlanzi zisondela ngokwanele ogwini.
Ukuzalela
Ukuvuthwa ngokocansi ku-sterlet kwenzeka esikhathini esisukela eminyakeni emi-4-8. Abesilisa basheshe bavuthwe. Izalela ngoMeyi-ekuqaleni kukaJuni, kuye ngesifunda. Ukuzalela kudlula phansi kwetshe elinetshe eliphansi phezulu emifuleni. Ukuzala kuphezulu impela. Izinhlanzi zifuywa futhi zikhuliswe ezindaweni zokuchanyuselwa izinhlanzi. Abantu baye bazalanisa ama-hybrids amaningana futhi banciphisa isikhathi sokuvuthwa kwamafomu amasiko.
