Zvese nezve sterlet nekuredza kwayo
Mhuka dzesturgeon dzakanyorwa muRed Book (IUCN-96 Red List, Appendix 2 yeCITES) uye ndeyeboka rekutanga rezvishoma - vanhu vega vemarudzi akapararira ari mungozi.
Ndapota cherechedza kuti hove yesturgeon inogona kungobatwa mumvura yakabhadharwa.
Mumiririri mudiki wemhuri yesturgeon. Pasinei nekuti kune zviitiko zvinozivikanwa zvekubata zvienzaniso zvema 16 kg, pakati pevamwe vamiririri vesturgeon genus, sterlet inogona kuonekwa sehove duku (kunyanya mienzaniso ye 1-2 kg inouya, dzimwe nguva kusvika 6 kg). Kureba kwehove kunosvika 1,25 m. Iyo yakasiyana kubva kune mamwe marudzi eRussia sturgeon nenhamba huru ye lateral "bugs". Mamwe masayendisiti anopokana kuti kune misiyano yevakadzi mune zvinofarirwa nechikafu mu sterlet. Vanhu vechirume vanoomerera pakudya kune invertebrates mukukurumidza ikozvino mukoramu yemvura, uye vanhukadzi vanoratidzwa nekudya kwepedyo-pasi munzvimbo dzakadzikama dzedhamu. Kuvapo kwepasi kunoratidzawo vanhu vakuru vevanhurume vese.
Sterlet hove nzira
Kubata hove kweSterlet kune nzira dzakawanda dzakafanana nekubata mamwe masturgeons, akagadziridzwa nehukuru. Kazhinji kazhinji inobatwa nekusabatwa-batwa paunenge uchiredza dzimwe hove. Nzvimbo yepasi yemuromo inoratidza nzira yavo yekudyisa. Kuredza kwekunakidzwa mumvura zhinji dzechisikigo kunorambidzwa kana kunyatsogadziriswa. Icho chinhu chekuberekesa mumatura etsika. Zvakakodzera kukurukura nemuridzi wedhamu pachine nguva mamiriro ezvinhu umo kubata hove kunoitika. Paunenge uchibata hove pakubata-uye-kusunungura hwaro, iwe unozonyanya kushandisa zvikorekedzo zvisina barbs. Kubata hove kweSterlet kunogoneka nerubatsiro rwepasi uye giya rekuyangarara, chero chirauro chiri pazasi pechidziva. Pazasi tackle inogona kuve yakareruka, kazhinji uchishandisa kuruka tsvimbo. Munzizi, sterlet inoramba ichienda kune yazvino. Vagari vomunharaunda vanogara kumahombekombe enzizi dzakapfuma mu sterlet vanozivikanwa ne "rubber bands". Munguva yechando, hove haishande, uye kubatwa kwayo kunongoitika.
Kubata sterlet pagiya rezasi
Usati waenda kudhamu uko sturgeon inowanikwa, tarisa mitemo yekuredza hove iyi. Kubata hove mumapurazi ehove kunodzorwa nemuridzi. Muzviitiko zvakawanda, kushandiswa kwehupi hwehupi hwepasi matanda uye zvokudya zvekudya zvinobvumirwa. Usati wabata hove, tarisa ukuru hwemikombe inokwanisika uye yakakurudzirwa chirauro kuitira kuti uzive inodiwa mutsara simba uye hoko saizi. Chinhu chakakosha pakubata sturgeon chinofanira kunge chiri mambure makuru ekumhara. Kuredza uye kunhonga kwakanakira vazhinji, kunyangwe vasina ruzivo vanobata hove. Vanobvumira mubati wehove kuti afambe-fambe padziva, uye nekuda kwekukwanisa kwekudya kwemavara, vanokurumidza "kuunganidza" hove panzvimbo yakapiwa. Feeder uye picker, semhando dzakasiyana dzemidziyo, ikozvino inosiyana chete mukureba kwetsvimbo. Hwaro ndiko kuvapo kwechirauro-chinonyura (feeder) uye matipi anochinjika patsvimbo. Misoro inoshanduka zvichienderana nemamiriro ekubata hove uye huremu hwekudyisa hunoshandiswa. Makonye akasiyana-siyana, nyama yegomba uye zvichingodaro anogona kushanda semuromo wekubata hove.
Iyi nzira yekubata hove inowanikwa kune wese. Tackle haidiwe zvekuwedzera zvishongedzo uye nyanzvi michina. Unogona hove munenge chero muviri wemvura. Ngwarira kusarudzwa kwevanodyisa muchimiro uye saizi, pamwe nemasanganiswa echirauro. Izvi zvinokonzerwa nemamiriro ezvinhu emvura (rwizi, dziva, nezvimwewo) uye zvido zvekudya zvehove dzemunharaunda.
Kubata sterlet pagiya rekuyangarara
Float rigs zvekuredza sterlet zviri nyore. Zviri nani kushandisa tsvimbo ne "running rig". Nekubatsirwa kwereel, zviri nyore kwazvo kutakura zvienzaniso zvakakura. Equipment uye mitsara yekubata hove inogona kunge ine yakawedzera simba zvivakwa. Iyo tackle inofanira kugadziriswa kuitira kuti muromo uri pasi. Matekiniki akajairika ekuredza akafanana nekuredza netsvimbo dzepasi. Kana pasina kurumwa kwenguva yakareba, unofanirwa kushandura nzvimbo yekubata hove kana kushandura muromo. Unofanira kubvunza vabati vehove vane ruzivo kana varongi vehove nezvekudya kwehove dzemuno.
Zviredzo
Iyo sterlet inopindura nyore nyore kune dzakasiyana siyana dzemhuka dzakabva: makonye, mago uye mamwe invertebrate mhute. Imwe yesarudzo huru dzekudya ndeye nyama yehove. Hove, semamwe ma<em>sturgeon, inopindura zvakanaka kune zviredzo zvinonhuhwirira.
Nzvimbo dzekuredza uye dzekugara
Hove dzinoparadzirwa zvikuru. Nzvimbo yekugovera inotora mabheseni eBlack, Azov neCaspian Seas, iyo Arctic Ocean. Iyo peculiarity ye sterlet ndeyekuti inofarira kuyerera kwemvura. Pasinei nekuparadzirwa kwayo kwakakura, inoonekwa sehove isingawanzo uye yakachengetedzwa munzvimbo zhinji. Iyo sterlet inobatwa nechisimba nevanobirira zvisiri pamutemo, nepo isingatenderi kusvibiswa kwedhamu nemvura ine tsvina kubva kumabhizinesi nekurima. Zvakare, sterlet vanhu vari munzvimbo inosiririsa panzizi uko kune huwandu hukuru hwema hydraulic zvimiro kana mamiriro ekugara achinja. Kuredza hove kunodzorwa nekupa marezinesi. Vabati vehove vane ruzivo vanotenda kuti iyo inoshanda sterlet inofarira kugara munzvimbo dzine mwero ikozvino uye pasi rakati sandara. Munguva yezhora, hove dzinosvika pedyo zvakakwana nemhenderekedzo.
Kubereka
Kukura kwepabonde mu sterlet kunoitika munguva kubva pamakore 4-8. Varume vakura kare. Inobereka muna May-kutanga kwaJune, zvichienderana nenharaunda. Kuberekesa kunopfuura nepasi pematombo-matombo ekumusoro kwenzizi. Kubereka kwakanyanyisa. Hove dzinopfuyiwa uye dzinochengetwa munzvimbo dzinoberekeswa hove. Vanhu vakabereka mahybrids akawanda uye vakaderedza nguva yekukura kwemhando dzetsika.
