Nzira yekusarudza sterlet

Izvo zvinodikanwa kuti usarudze sterlet zvinoenderana kwete chete nemitemo yakajairika yekutenga hove, asi zvakare uzviongorore zvinoenderana nehumwe hunhu. Kana paine kunyangwe kukahadzika kushoma, saka unofanirwa kuramba kuitenga. Hove dzakaparadzwa hadzizongonanzva zvakaipa chete, asiwo zvine njodzi kuhutano.

Ndeipi sterlet yaunogona kutenga:

• iyo pamusoro peiyo chilled sterlet inofanirwa kugara yakanyorova, asi kwete inonamira kana zvakare kutsvedza;
• chero zvikanganiso zviri pamusoro peiyo sterlet hazvibvumirwe (munzvimbo dzekukuvara, mabhakitiriya anoumba ipapo, izvo zvinomhanyisa maitiro ehove dzinoora);
• maziso eiyo sterlet anofanirwa kuve akachena uye "otarisa" zvakaenzana (kana "kutarisisa" kwehove yakanangiswa kumusoro, saka pasherufu hupenyu hwayo hwakareba);
• kana uchimanikidza paganda re sterlet nemunwe, hapafanirwe kuve nemaburi (iyi nzira yekuongorora inoshanda chete kune hove inotonhorera, kuyedza kwakadai hakushandire chigadzirwa chakaomeswa);
• ma gill eiyo nyowani sterlet anogara akajeka uye aine hunhu mutsvuku (iwo ma gill anofanira kuve akachena);
• kana uchicheka, nyama yeiyo nyowani sterlet inogara ichinetsa kupatsanura nemapfupa;
• chando sterlet haifanire kusiyaniswa nechando chakawandisa kana chando (kana paine chando chakawandisa, uye pane yero kana pingi pingi pamusoro payo, iyo hove yakaomeswa kanopfuura kamwe);
• yakanyorova kana chando sterlet inofanira kugara yakachena (matonhorwa echando emarara, kusvibiswa mumagill kana mune dzimwe nzvimbo dzehove chiratidzo chekutyora mitemo yekubata, kuendesa uye kuichengeta).

Kana iyo sterlet yakatengwa yakaoma kuita chando, saka inofanirwa kunyungudutswa zvakasikwa kana mumvura inotonhorera. Mushure mekunyungudika, hove dzinofanirwa kuchengetedza chimiro uye hwema hwehove hwehunhu.

Ndeipi sterlet isingafanire kutengwa:

• kana iyo yepamusoro yehove yakatonhora yaoma kana mamukisi ari kuoneka, saka unofanira kuramba kuitenga (iyo hove yakachengetwa zvisina kunaka kana kutanga kudzikira);
• kana hunhu hwehove hune hunhu hwekunze, saka haugone kutenga sterlet (munhuhwi unogona kunge wakaora kana kufanana neforoma);
• yero inotumbuka pahove inogara iri chiratidzo chekuparadza (kutumbuka kunogona kuve muchimiro chemavara kana mitsara);
• haufanire kutenga sterlet kana paine maronda, kukuvara kana mavara easina kuzivikanwa pamusoro payo);
• grey gills inogona kuwanikwa chete mu sterlet, iyo yakachengetwa zvisirizvo kwenguva yakareba (chero zvisirizvo kubva kune tsvuku hue mune iyi kesi inofanirwa kuve chikonzero chekuramba kutenga hove);
• kana nyama ichipatsanuka kubva pamapfupa zvakanyanya kana uchicheka sterlet, saka hove haisi nyowani (kana nuance yakadaro inosanganiswa nekunhuhwirira kwakasviba uye mamasi paganda, saka hapana kana iyo sterlet inofanirwa kudyiwa);
• kana, kana uchimanikidza paganda reiyo sterlet nemunwe, chigunwe chinoramba chiripo, iyo hove inonyatso stale (iyo sterlet inogona kutanga kudzikira, yakadzokororwa nechando kana kunyungudutswa kana kuchengetwa zvisirizvo);
• hove dzakatonhora dzinogona kutengeswa pamashefu ezvitoro kwenguva yakati (semutemo, haapfuure mazuva gumi nemana), saka kana paine fungidziro, zvirinani kubvunza mutengesi chitupa chinotaura musi wekubata sterlet. uye iyo nguva yekusunungurwa kwayo iri kutengeswa).

Panzvimbo pezviyero, sterlet ine mhando yemapfupa mahwendefa ayo anogona kunge ari zviratidzo zveutsva hwehove. Kana ivo vakaringana zvakanaka kune muviri, saka iyo sterlet iri nyowani. Kana mahwendefa abviswa, hazvingakwanise kutumidza hove yemhando yepamusoro.
