Zonse za sterlet ndi kuwedza
Mitundu ya sturgeon yalembedwa mu Red Book (IUCN-96 Red List, Appendix 2 ya CITES) ndipo ili m'gulu loyamba lazosowa - anthu amitundu yomwe ili pachiwopsezo.
Chonde dziwani kuti nsomba za sturgeon zimatha kugwidwa m'madzi olipidwa.
Woimira wamng'ono wa banja la sturgeon. Ngakhale pali milandu yodziwika yogwira zitsanzo za pafupifupi 16 kg, pakati pa ena oimira mtundu wa sturgeon, sterlet ikhoza kuonedwa ngati nsomba yaing'ono (makamaka zitsanzo za 1-2 kg zimabwera, nthawi zina mpaka 6 kg). Kutalika kwa nsomba kumafika mamita 1,25. Zimasiyana ndi mitundu ina ya sturgeon yaku Russia ndi "nsikidzi" zambiri zam'mbali. Asayansi ena amatsutsa kuti pali kusiyana pakati pa amuna ndi akazi pazokonda zakudya mu sterlet. Amuna amamatira kudyetsa zamoyo zopanda msana m'mphepete mwa madzi, ndipo akazi amadziwika ndi zakudya zotsika kwambiri m'madera ozizira a nkhokwe. Kukhala pansi ndi khalidwe la anthu akuluakulu a amuna ndi akazi.
Njira zophera nsomba za sterlet
Usodzi wa sterlet uli m'njira zambiri zofanana ndi kugwira nsomba zina, zosinthidwa kukula. Nthawi zambiri zimakhala zongopeka popha nsomba zina. M'munsi malo pakamwa amaonetsa njira yawo yodyera. Kusodza kosangalatsa m'madzi ambiri achilengedwe ndikoletsedwa kapena kumayendetsedwa mosamalitsa. Ndi chinthu cha kuswana mu nkhokwe za chikhalidwe. Ndikoyenera kukambirana ndi mwiniwake wa malo osungiramo madzi pasadakhale momwe nsomba zimachitikira. Mukawedza nsomba ndi kumasula, mudzayenera kugwiritsa ntchito mbedza popanda mipiringidzo. Kupha nsomba za sterlet ndizotheka mothandizidwa ndi zida zapansi ndi zoyandama, pokhapokha nyamboyo ili pansi pa dziwe. Kuwongolera pansi kungakhale kosavuta, nthawi zambiri pogwiritsa ntchito ndodo zopota. M'mitsinje, sterlet imapitilirabe mpaka pano. Anthu okhala m'mphepete mwa mitsinje yolemera mu sterlet amadziwika ndi "magulu a rabara". M’nyengo yozizira, nsombazi sizigwira ntchito, ndipo zimangochitika mwachisawawa.
Kugwira sterlet pa gear pansi
Musanapite kumalo osungiramo nsomba zomwe zimapezeka nsomba, fufuzani malamulo opha nsomba. Kupha nsomba m'mafamu a nsomba kumayendetsedwa ndi eni ake. Nthawi zambiri, kugwiritsa ntchito ndodo zilizonse zapansi ndi zokhwasula-khwasula zimaloledwa. Musanasodze, fufuzani kukula kwa zikho zotheka ndi nyambo yovomerezeka kuti mudziwe mphamvu ya mzere ndi kukula kwa mbedza. Chothandizira chofunikira kwambiri pogwira sturgeon chiyenera kukhala ukonde waukulu wotera. Usodzi wodyetsera ndi wotolera ndiwosavuta kwa ambiri, ngakhale asodzi osadziwa. Amalola msodzi kuti azitha kuyenda padziwe, ndipo chifukwa cha kuthekera kwa kudyetsera malo, "amasonkhanitsa" nsomba pamalo omwe apatsidwa. Wodyetsa ndi wosankha, monga mitundu yosiyana ya zipangizo, panopa amasiyana mu utali wa ndodo. Maziko ndi kukhalapo kwa nyambo chidebe-sinker (wodyetsa) ndi nsonga kusinthana pa ndodo. Pamwamba pamasintha malinga ndi momwe nsomba zimakhalira komanso kulemera kwa chodyera chomwe chimagwiritsidwa ntchito. Mitundu yosiyanasiyana ya nyongolotsi, chipolopolo cha nyama ndi zina zotero zimatha kukhala ngati mphuno ya nsomba.
Njira yopha nsombayi imapezeka kwa aliyense. Kulimbana sikukufuna zowonjezera zowonjezera ndi zida zapadera. Mukhoza nsomba pafupifupi madzi aliwonse. Samalani ndi kusankha kwa feeders mu mawonekedwe ndi kukula, komanso nyambo zosakaniza. Izi ndichifukwa cha momwe malo osungiramo madzi amakhalira (mtsinje, dziwe, ndi zina zotero) ndi zakudya zomwe nsomba zam'deralo zimakonda.
Kugwira sterlet pa zida zoyandama
Zida zoyandama za usodzi wa sterlet ndizosavuta. Ndikwabwino kugwiritsa ntchito ndodo ndi "rig yothamanga". Mothandizidwa ndi reel, ndikosavuta kukoka zitsanzo zazikulu. Zida ndi mizere ya nsomba zimatha kukhala ndi mphamvu zowonjezera mphamvu. Chophimbacho chiyenera kusinthidwa kuti mphuno ikhale pansi. Usodzi wamba ndi wofanana ndi kusodza ndi ndodo zapansi. Ngati palibe kulumidwa kwa nthawi yayitali, muyenera kusintha malo osodza kapena kusintha nozzle. Muyenera kufunsa asodzi odziwa zambiri kapena otsogolera usodzi za kadyedwe ka nsomba zam'deralo.
Nyambo
Sterlet imayankha mosavuta nyambo zosiyanasiyana zochokera ku nyama: mphutsi, mphutsi ndi mphutsi zina zopanda msana. Chimodzi mwazakudya zazikulu ndi nyama ya nkhono. Nsomba, mofanana ndi nsomba zina za sturgeon, zimachita bwino ndi nyambo zonunkhira.
Malo ausodzi ndi malo okhala
Nsombazi zimagawidwa kwambiri. Malo ogawa amatenga mabeseni a Nyanja Yakuda, Azov ndi Caspian, Nyanja ya Arctic. Chodabwitsa cha sterlet ndikuti imakonda malo osungira madzi. Ngakhale kuti imafalitsidwa kwambiri, imatengedwa kuti ndi nsomba yosowa komanso yotetezedwa m'madera ambiri. Sterlet amagwidwa ndi nyama zolusa, pomwe samalekerera kuipitsidwa kwa malo osungiramo madzi otayira kuchokera kumabizinesi ndi ulimi. Komanso, anthu a sterlet ali m'malo oyipa pamitsinje pomwe pali zida zambiri zama hydraulic kapena malo okhala asintha. Usodzi umayendetsedwa ndi chilolezo. Asodzi odziwa bwino ntchito amakhulupirira kuti sterlet yogwira imakonda kukhala m'malo okhala ndi madzi otentha komanso pansi. Panthawi ya zhora, nsomba imayandikira pafupi ndi gombe.
Kuswana
Kukhwima kwa kugonana mu sterlet kumachitika kuyambira zaka 4-8. Amuna amakhwima kale. Imamera mu Meyi-koyambirira kwa Juni, kutengera dera. Kuswana kumadutsa pamiyala-miyala yomwe ili pamwamba pa mitsinje. Kubereka kumakhala kwakukulu. Nsomba zimaŵetedwa ndikuweta m’malo osungiramo nsomba. Anthu amaŵeta angapo hybrids ndi kuchepetsa nthawi kusasitsa za chikhalidwe mitundu.
