Umsoco we-Crayfish: yiziphi izinhlanzi ezisetshenziselwa ukudla emvelweni nokuthi zondliwa ini ekuthunjweni

Emazweni amaningi (kuhlanganise neRussia), inyama ye-crayfish ibhekwa njengento ewuju. Abantu bayakujabulela ukudla lesi sibiliboco. Kodwa kukhona isigaba esinjalo sabantu ababheka i-crayfish hhayi ukudla okukhangayo kakhulu. Isizathu salokhu “kunengeka” kuwumbono ongamanga wokudla okunempilo kwale arthropod.

Abanye bakholelwa ukuthi lezi zilwane zidla ukubola nokubola. Kodwa lokhu akulona iqiniso ngokuphelele. Kulesi sihloko sizokhuluma ngokuthi ama-arthropods adlani.

Isilwane esinjani leso?

Ngaphambi kokukhuluma ngalokho okudliwa yi-crayfish, kufanelekile ukwazi lezi zakhamuzi ze-arthropod zesici samanzi. Lezi zilwane zingama-invertebrate crustaceans. Kunezinhlobo eziningi, uma sibala ezimbalwa nje ezivame kakhulu:

• YaseYurophu;
• EMpumalanga Ekude;
• eCuba;
• eFlorida;
• imabula;
• I-Mexican pygmy, njll.

Umdlavuza usabalaliswe kakhulu kuwo wonke amazwekazi. Indawo yabo yimifula enamanzi ahlanzekile, amachibi, amachibi nezinye izizinda zamanzi. Ngaphezu kwalokho, izinhlobo eziningana zingaphila endaweni eyodwa ngesikhathi esisodwa.

Ngaphandle, umdlavuza ubukeka uthakazelisa kakhulu. Uyenzile izigaba ezimbili: i-cephalothorax nesisu. Ekhanda kukhona amapheya amabili ezimpondo namehlo ahlangene. Futhi isifuba sinezitho eziyisishagalombili, ezimbili zazo ziyizinzipho. Emvelweni, ungathola umdlavuza wemibala ehluke kakhulu ukusuka kokunsundu nokuluhlaza ukuya kokuluhlaza okwesibhakabhaka nokubomvu. Ngesikhathi sokupheka, zonke izingulube ziyahlakazeka, kusele okubomvu kuphela.

Inyama yomdlavuza ithathwa njengesibiliboco ngesizathu. Ngaphezu kokunambitheka okuhle kakhulu, ayinawo amafutha, ngakho-ke inokuqukethwe kwekhalori ephansi. Ngaphezu kwalokho, inyama iqukethe izinto eziningi eziwusizo. Kukhona i-calcium, ne-iodine, novithamini E, futhi cishe nawo wonke amavithamini eqembu B.

Udlani?

Ngokuphambene nenkolelo evamile yokuthi ama-crayfish adla ukubola, anjalo ukukhetha ekudleni. Pho zidlani izinkalankala? Uma izithasiselo zokwenziwa zokwenziwa namakhemikhali zikhona ekudleni, khona-ke le arthropod ngeke iyithinte. Ngokuvamile, lezi zakhamuzi zamadamu zizwela kakhulu ukuhlanzeka kwendawo ezungezile. Emadolobheni amaningi, “bakhonza” ezinsizeni zamanzi. Amanzi angena kubo udlula emanzini ane-crayfish. Ukusabela kwabo kugadwe izinzwa eziningi. Uma amanzi equkethe izinto eziyingozi, ama-arthropods azokwazisa ngokushesha ngakho.

Ama-crustaceans ngokwawo angama-omnivores. Ukudla kwabo kuqukethe ukudla kokubili kwezilwane nemifino. Kodwa uhlobo lwesibili lokudla yilona oluvame kakhulu.

Okokuqala, uzodla ulwelwe olubanjiwe, utshani obusogwini namaqabunga awile. Uma lokhu kudla kungatholakali, khona-ke izinhlobonhlobo zeminduze yamanzi, i-horsetail, i-sedge izosetshenziswa. Abadobi abaningi baqaphela ukuthi ama-arthropods adla izimbabazane ngokujabula.

Kodwa umdlavuza ngeke udlule ekudleni okuvela ezilwaneni. Uzokujabulela ukudla izibungu zezinambuzane kanye nabantu abadala, ama-mollusks, izikelemu nama-tadpoles. Kuyaqabukela, umdlavuza ukwazi ukubamba izinhlanzi ezincane.

Uma sikhuluma ngezinsalela ezibolayo zezilwane, khona-ke lokhu kubhekwa njengesinyathelo esidingekayo. Umdlavuza uhamba kancane futhi akwenzeki ngaso sonke isikhathi ukubamba “inyama entsha”. Kodwa ngesikhathi esifanayo, isilwane singadla kuphela ukudla kwezilwane okungabolile kakhulu. Uma izinhlanzi ezifile sezibolile isikhathi eside, i-arthropod izomane idlule.

Kodwa noma kunjalo ukudla kwezitshalo kwakha isisekelo sokudla. Zonke izinhlobo zolwelwe, izitshalo zasemanzini nezasemanzini, zenza ukudla okungafika ku-90%. Konke okunye akuvamile ukudliwa uma ukwazile ukukubamba.

Lezi zilwane zidla ngenkuthalo kuphela ngenkathi efudumele. Njengoba kuqala ubusika, banesiteleka sokulamba esiphoqelelwe. Kodwa ngisho nasehlobo isilwane asidli njalo. Ngokwesibonelo, eyeduna idla kanye noma kabili ngosuku. Futhi insikazi idla kanye kuphela ezinsukwini ezimbili noma ezintathu.

Ziyini ukudla ama-crayfish lapho zizalela ekuthunjweni?

Namuhla, i-crayfish ivame ukutshalwa ngokwenziwa. Ukuze wenze lokhu, amapulazi adalwe emachibini, emachibini amancane noma kusetshenziswa iziqukathi zensimbi. Njengoba umgomo oyinhloko webhizinisi elinjalo ukuthola inqwaba enkulu, bondla ama-arthropods ngokudla equkethe amandla amaningi. Iya kokuphakelayo:

• inyama (eluhlaza, ebilisiwe kanye nanoma iyiphi enye indlela);
• isinkwa;
• okusanhlamvu okuvela kokusanhlamvu;
• imifino;
• amakhambi (ikakhulukazi ama-crayfish athanda izimbabazane).

Ngesikhathi esifanayo, ukudla kufanele kunikezwe kakhulu kangangokuthi kudliwe ngaphandle kwensalela. Uma kungenjalo, izoqala ukubola futhi ama-arthropods azomane afe. Njengomthetho, umthamo wokudla akufanele ube ngaphezu kwamaphesenti angu-2-3 wesisindo sesilwane.

Muva nje, abaningi baqale ukugcina lezi zilwane endlini, ku-aquarium. Kulokhu, umbuzo uphakama: yini okufanele ukondle? Uma kukhona isitolo sezilwane edolobheni, ungathenga ukudla lapho. Ezixubeni ezikhethekile zama-arthropods kukhona wonke amavithamini namaminerali adingekayo empilweni yawo.

Hhayi-ke, uma kunzima ukuthola ukudla, noma sekuphelile, ungakondla ngezicucu zenkukhu noma enye inyama, ulwelwe, izikelemu kanye nazo zonke izimbabazane. Njengoba ama-crayfish ezwela kakhulu ekuhlanzekeni kwemvelo, kuyadingeka ukuqinisekisa ukuthi izinsalela zokudla azishiywa ku-aquarium isikhathi esingaphezu kwezinsuku ezimbili.
