• zonse ndi zosadulidwa;
• matumbo;
• mazira;
• mu mawonekedwe a fillets, odzaza mu phukusi.

Momwe mungasankhire sterlet

Ndikofunikira kusankha sterlet molingana ndi malamulo onse ogula nsomba, komanso kuunika molingana ndi mikhalidwe ina. Ngati pali kukayikira ngakhale pang'ono, ndiye kuti muyenera kukana kugula. Nsomba zowonongeka sizidzangolawa zoipa, komanso zowopsa ku thanzi.

Ndi sterlet yanji yomwe mungagule:

• pamwamba pa chilled sterlet kuyenera kukhala konyowa nthawi zonse, koma osati kumata kapena kuterera kwambiri;
• zolakwika zilizonse pamwamba pa sterlet siziloledwa (m'malo owonongeka, mabakiteriya amapanga nthawi yomweyo, omwe amafulumizitsa njira yowola nsomba);
• maso a sterlet ayenera kukhala oyera ndi "kuyang'ana" mofanana (ngati "kuyang'ana" kwa nsomba kumayang'ana mmwamba, ndiye kuti moyo wake wa alumali ndi wautali kwambiri);
• Mukakanikiza pakhungu la sterlet ndi chala, sikuyenera kukhala ndi mano (njira yowunikirayi imagwira ntchito pa nsomba zozizira zokha, kuyesa koteroko sikungagwire ntchito yachisanu);
• ma gill a sterlet atsopano amakhala owala nthawi zonse ndipo amakhala ndi utoto wofiira (magalasi ayenera kukhala oyera);
• podula, nyama ya sterlet yatsopano nthawi zonse imakhala yovuta kupatukana ndi mafupa;
• sterlet wozizira sayenera kusiyanitsidwa ndi ayezi kapena chipale chofewa (ngati pali chipale chofewa, ndipo pamwamba pake pali utoto wachikasu kapena wapinki, ndiye kuti nsombayo idaundana kangapo);
• sterlet yoziziritsa kapena yowuma iyenera kukhala yoyera nthawi zonse (tinthu tating'ono tazinyalala tachisanu, kuipitsidwa m'matumbo kapena m'malo ena a nsomba ndi chizindikiro cha kuphwanya malamulo oti mugwire, kunyamula ndikusunga).

Ngati sterlet idagulidwa yozizira, iyenera kusungunuka mwachilengedwe kapena m'madzi ozizira. Akatha kusungunuka, nsombayo iyenera kukhalabe ndi mawonekedwe ake komanso fungo lamtundu wa nsomba.

Zomwe sterlet siziyenera kugulidwa:

• ngati pamwamba pa nsomba yoziziritsa ndi youma kwambiri kapena ntchentche ikuwoneka bwino, ndiye kuti muyenera kukana kugula (nsombayo inasungidwa molakwika kapena inayamba kuwonongeka);
• ngati fungo la nsomba lili ndi fungo lachilendo, ndiye kuti simungagule sterlet (fungo lingakhale lovunda kapena lofanana ndi nkhungu);
• chikasu pachimake pa nsomba nthawi zonse chizindikiro cha kuwonongeka (pachimake akhoza kukhala ngati mawanga kapena mikwingwirima);
• musagule sterlet ngati pali mikwingwirima, kuwonongeka kapena madontho osadziwika bwino pamtunda wake);
• gill imvi imatha kupezeka mu sterlet, yomwe yasungidwa molakwika kwa nthawi yayitali (zosiyana zilizonse kuchokera ku red hue pankhaniyi ziyenera kukhala chifukwa chokana kugula nsomba);
• ngati nyama imalekanitsa bwino ndi mafupa podula sterlet, ndiye kuti nsombayo si yatsopano (ngati phokoso lotere likuphatikizidwa ndi fungo lowawasa ndi ntchentche pakhungu, ndiye kuti palibe sterlet iyenera kudyedwa);
• ngati, pokanikizira pakhungu la sterlet ndi chala, chiboliboli chimakhalabe, ndiye kuti nsombayo imakhala yosasunthika (sterlet ikhoza kuyamba kuwonongeka, yasungidwa mobwerezabwereza kapena kusungunuka kapena kusungidwa molakwika);
• Nsomba zoziziritsa kukhosi zimatha kugulitsidwa pamashelefu kwanthawi yayitali (monga lamulo, osapitilira masiku 14), chifukwa chake, ngati pali zokayikitsa, ndi bwino kufunsa wogulitsa satifiketi yofotokoza tsiku la sterlet catch. ndi nthawi yoti idzatulutsidwe pa malonda).

M'malo mwa mamba, sterlet ili ndi mtundu wa mafupa omwe amatha kukhala zizindikiro za kutsitsimuka kwa nsomba. Ngati zimagwirizana bwino ndi thupi, ndiye kuti sterlet ndi yatsopano. Mambale akamasenda, sizingatheke kutchula nsomba yabwino.
