Ungayikhetha kanjani i-sterlet efanele?

I-sterlet ingenye yezinhlanzi ezinkulu. Ubukhulu bomuntu omdala bufinyelela ku-60 cm. Isici esihlukile sale nhlanzi yikhanda elibukhali, engxenyeni engaphambili lapho izimpondo ezimbili zibonakala ngokucacile. I-Sterlet ayinazo izikali, kodwa kukhona amapuleti afana nayo. Lolu hlobo lwezinhlanzi luthengiswa ngezinguqulo eziqandisiwe noma ezibandayo.

I-Sterlet ingathengiswa:

• ephelele futhi engasikiwe;
• amathumbu;
• iqandisiwe;
• ngendlela yama-fillet, afakwe emaphaketheni.

Indlela yokukhetha i-sterlet

Kudingekile ukukhetha i-sterlet ngokuhambisana nemithetho ejwayelekile yokuthenga izinhlanzi kuphela, kodwa futhi ukuyihlola ngokusho kwezinye izici zomuntu ngamunye. Uma kukhona ngisho nokungabaza okuncane, kufanele wenqabe ukuyithenga. Izinhlanzi ezonakele ngeke zinambitha ezimbi kuphela, kodwa futhi ziyingozi empilweni.

Iyiphi i-sterlet ongayithenga:

• ubuso be-sterlet epholile kufanele buhlale bumanzi, kodwa hhayi ukunamathela noma ukushelela kakhulu;
• noma yikuphi ukukhubazeka ebusweni be-sterlet akuvumelekile (ezindaweni zokulimala, amabhaktheriya enza ngokushesha, asheshisa inqubo yokubola kwezinhlanzi);
• amehlo e-sterlet kufanele ahlanzeke futhi "abuke" ngokulinganayo (uma "ukubuka" kwezinhlanzi kuqondiswe phezulu, khona-ke impilo yayo yeshalofu yinde kakhulu);
• lapho ucindezela esikhumbeni se-sterlet ngomunwe, akufanele kube namadents (le ndlela yokuhlola isebenza kuphela ezinhlanzi ezibandayo, lokho kuhlola ngeke kusebenze kumkhiqizo oqandisiwe);
• amagill we-sterlet amasha ahlala ekhanyayo futhi anesici esibomvu (amagill kumele ahlanzeke);
• lapho usika, inyama ye-sterlet entsha ihlale inzima ukuhlukana namathambo;
• I-sterlet efriziwe akufanele ihlukaniswe yiqhwa noma iqhwa eliningi (uma kuneqhwa eliningi, futhi kukhona i-tint ephuzi noma e-pinkish ebusweni bayo, khona-ke inhlanzi yayiqhwa izikhathi ezingaphezu kwesisodwa);
• I-sterlet ebandayo noma eqandisiwe kufanele ihlale ihlanzekile (izinhlayiya eziqandisiwe zemfucumfucu, ukungcoliswa kwama-gill noma kwezinye izindawo zezinhlanzi kuwuphawu lokwephulwa kwemithetho yokubamba, ukuthuthwa nokuyigcina).

Uma i-sterlet ithengwa eqandisiwe, kufanele incibilikiswe ngokwemvelo noma emanzini abandayo. Ngemva kokuncibilika, inhlanzi kufanele igcine ukuma kwayo kanye nephunga lendabuko lenhlanzi.

Iyiphi i-sterlet akufanele ithengwe:

• uma ubuso benhlanzi ebandayo bomile kakhulu noma i-mucus ibonakala ngokucacile, khona-ke kufanele wenqabe ukuyithenga (inhlanzi yayigcinwe ngendlela engafanele noma yaqala ukuwohloka);
• uma iphunga elimnandi le-fishy liqukethe iphunga elingaphandle, awukwazi ukuthenga i-sterlet (iphunga lingase libole noma lifane nesikhunta);
• ukuqhakaza okuphuzi ezinhlanzini kuhlale kuwuphawu lokubola (ukuqhakaza kungaba ngesimo samabala noma imivimbo);
• akufanele uthenge i-sterlet uma kukhona imihuzuko, umonakalo noma amabala emvelaphi engaziwa ebusweni bayo);
• ama-gray gill angatholakala kuphela ku-sterlet, egcinwe ngokungalungile isikhathi eside (noma yikuphi ukuphambuka okuvela ku-red hue kulokhu kufanele kube isizathu sokwenqaba ukuthenga izinhlanzi);
• uma inyama ihlukana kahle namathambo lapho usika i-sterlet, khona-ke izinhlanzi azintsha (uma i-nuance enjalo ihlangene nephunga elimuncu kanye ne-mucus esikhumbeni, ngakho-ke akufanele kudliwe i-sterlet enjalo);
• uma, lapho ucindezela esikhumbeni se-sterlet ngomunwe, i-dent isala, khona-ke inhlanzi isidala (i-sterlet ingaqala ukuwohloka, ifakwe iqhwa ngokuphindaphindiwe noma incibilikile noma igcinwe ngokungalungile);
• izinhlanzi ezibandayo zingathengiswa emashalofini esitolo isikhathi esithile (njengomthetho, kungakapheli izinsuku eziyi-14), ngakho-ke, uma kukhona izinsolo, kungcono ukubuza umdayisi isitifiketi esisho usuku lokubamba i-sterlet. kanye nesikhathi sokukhululwa kwayo ekuthengisweni).

Esikhundleni sezikali, i-sterlet inohlobo lwamapuleti amathambo angaba izinkomba zokusha kwezinhlanzi. Uma zilingana kahle emzimbeni, i-sterlet isha. Lapho amapuleti ehlutshiwe, ngeke kwenzeke ukubiza inhlanzi yekhwalithi.
