Eyikati Afrika: ukutshala kanye zizalela

Ngokuqinisekile, wonke kubonakala zokudla izitolo izinhlanzi zokubala zemabula eyikati. Futhi kakhulu efana lolu hlobo inhlanzi, ngoba inyama yayo ngempela namanzi, soft futhi esihlwabusayo. Kodwa akubona bonke abantu uyazi ukuthi le nhlanzi kungaba lula impela sikhule bebodwa noma inhlanzi epulazini elincane. Kulesi sihloko sizohlola imithetho yokuzalanisa nokukhulisa zezinhlanzi epulazini, kodwa ngendlela efanayo ungakwazi ukhule eyikati ukudliwa siqu.

eyikati

Ngokuvamile, "eyikati zemabula '- hhayi ngempela igama esifanele le nhlanzi. Empeleni, igama layo - (. Latin Clarias gariepinus) Clarias gariepinus. Lezi zinhlanzi zimila Afrika. Ngisho emanzini yeSahara ungakwazi ukubamba Nile klariasa. Ngokubukeka kuba eyikati abavamile kakhulu, umzimba wakhe isikhathi eside izindawo ensundu has a esiswini elikhanyayo. Isici esiphawulekayo zonke eyikati - amadevu eside. Ngo Klarius Intshebe kakhulu ngendlela 4 Imibhangqwana. Lolu hlobo izinhlanzi uyakwazi ukucubungula i-oksijini evela emoyeni ngokusebenzisa nadzhaberny isitho zokuphefumula. Ngenxa yale njongo, eyikati kuziwa kwamanzi futhi ayegcwele emoyeni. Kuyinto lesi sici wenza Klarius lula kangaka kulinywe. Asikho isidingo ukunikeza ke ngamanzi ahlanzekile. Ngaphezu kwalokho, omunye imitha cubic yamanzi kungenziwa itshalwe mayelana 300 khilogremu izinhlanzi bukhoma. Yiqiniso, lokhu kungenzeka kuphela ukususwa njalo indle.

Ukuze semali izinhlanzi udinga noma ukuthenga amachibi akhethekile noma ukufinyelela umzimba ngokwanele amanzi amaningi. Omunye izici indlela - kungenzeka ukusetshenziswa ngokwengeziwe amanzi afudumele we iyindawo, okuholela imiphumela engcono.

abakhiqizi

Iningi abalimi - inhlanzi ezikhula ngokushesha kunezinye. eyikati Afrika bayakwazi ukubamba iqhaza yokuzalanisa 1.5 - 2 iminyaka. Abesifazane ukufinyelela izinga lokuzala at 6 izinyanga, kodwa imiphumela emihle etholakala eneminyaka engu-iminyaka engu-2.

Ngokuvamile, ngesikhathi yokuzalela isitokwe umzali zifakwa emathangini ngabanye, lapho amanzi ayithinta ngayo ukuba 23-25 degrees Celsius. abakhiqizi Okuphakelayo kumelwe silinganiswe ngokucophelela. Okuqukethwe amaprotheni endaweni ukudla kufanele okungenani 38%. Abenzi usuku kudingeka sidle ukudla okungenani 1.5% yesisindo sayo.

Inombolo kahle abakhiqizi kwelinye rybopriemnike - ngabanye 100.

Lokuzaliswa ngaphansi kolawulo

Ngokuvamile ngenxa yobulili imikhiqizo high quality, abakhiqizi zishukumisa i-hormone imijovo. Ngaphambi kokuqala nokuphathwa hormone ukuba zisakazwe nabesifazane okugcinwa noma amachibi ahlukahlukene.

izinsuku ezingu-2-3 ngaphambi inqubo zidala kuyadingeka ukubeka izinhlanzi ukudla ngenxa yendlala. Single umthamo umjovo ukusetshenziswa pituitary ngayinye 4.5 mg ngayinye amakhilogramu esisindo neyezinhlanzi.

Afrika eyikati zizalela, linqume ukuhlakaza ukukhiqiza ngomjovo, iyaphendula ngokuphelele «Ovopel». Iqondiswa kanye, usebenzisa eyodwa bead kilogram izinhlanzi ngayinye. Lokhu ukulungiselela isetshenziswa ngendlela ingxube bokuphila. Ngaphambi zidala kwabesilisa igcinwe echibini.

zidala

Ukuze nokuvuthwa ngempumelelo amaqanda kufanele ugcine ukuba izinsikazi zidala emanzini nge lokushisa mayelana 26. nge-ovulation Okugcwele kwenzeka ngaphakathi 12 ihora. Emva umjovo we pituitary.

eyikati Afrika - ngempela inhlanzi sezinzwa, ngakho ukuthola amaqanda abesifazane kumele elaliswa. Lokhu kwenziwa esasikhipha umuthi wokubulala izinzwa. kuvame kakhulu ukuba kusetshenziswe «Propiscin».

Amaqanda ezivezwa ngamunye besifazane eceleni. It kuyothathwa osekuyisikhathi uma nenqwaba amaqanda okungenani u-20% ngesisindo sezinti ngabanye ethile. Emva inqubo zesifazane afakwe isixazululo KMnO4na isikhathi esicishe sibe ihora elilodwa. Umuthi kumele buhlanjululwe ngesilinganiso 0.5 g ngalinye amalitha 100 amanzi.

Milt ingxenye enkulu othathwe gonads asibambanga kwabesilisa. Kusebenta isidoda egcinwe amahora angu-24 ezingeni lokushisa - 4 degrees.

kokukhulelwa

Amaqanda okuholela bahlukaniswa baba izigaba ezintathu. Amaqanda abesifazane ezahlukene kungcono hhayi uhlanganise. bakhonze ngamunye kufanele ahlaziye mayelana 300 amagremu. Khona-ke thatha 3 ml ubisi. Ukuphumelela kuyoba ephakeme uma ubisi kuzosuka kwabesilisa ezahlukene - kuyasivusa inqubo sokukhulelwa. Ngakho, kungcono ukuthatha 1 ml 3 kwabesilisa. Milt futhi Roe horoshenechko aphansi emanzini futhi baphehla cishe imizuzu emihlanu.

degumming

Uma kwenziwe kokukhulelwa, amaqanda kumele engahashazanga kahle. Ngenxa yalesi ukusebenzisa isixazululo tannin. Kuthatha cishe 10 amagremu ngasinye 10 amalitha amanzi. Ukuze ngokugcwele amaqanda obeskleit kufanele kahle wageza nge isixazululo ngemizuzwana engaphansi kuka-30.

bayashintshana ekufukameleni

Ngemva amaqanda obeskleena, uqala e-ugqoko bayashintshana ekufukameleni ku yinoma yimuphi amadivayisi ezikhethekile. Ozimele bayashintshana ekufukameleni kumele okuqoqiwe anezikhala nge anezikhala of mayelana 0.5 mm. Caviar oluhlukaniswe igridi ungqimba amaqanda 1. Lapho izinga lokushisa lamanzi akazidluli 27 degrees kwenzeka ukuvela izibungu. Kusukela ekukhulelweni kuze izibungu ubabonisa mayelana 25 amahora. Amanzi ugqoko edliwe ngesilinganiso esingamaphesenti 10 amalitha ngomzuzu.

Ukugcina izibungu

Izibungu kufanele sigcinwe emathileyi noma emachibini amancane ukuze resorption ye-yolk sac. Kungaba ku ngezinsuku zokuqala ezimbili ukubeka isibungu echibini, bese ususa ku emathileyi.

Clarias gariepinus, izibungu kufanele igcinwe ebumnyameni. Ngemva kwezinsuku ezintathu emva resorption yokugcina ye-yolk sac kuyadingeka ukususa ifilimu, embozwe isikhunta, kusukela phansi ugqoko. Uma izibungu bakhuthale - ngakho -yolk sac is ziyoncibilika ngokuphelele.

elalikudle lapho liseyisibungu ukukhulisa izigaba

Isigaba sokuqala ithatha cishe 3 amaviki. Ekupheleni kwalo kwenzeka uma ukuphefumula eyikati Afrika iqala i-oksijini evela emoyeni.

Ukutshala izibungu ngale nkathi elilingana amayunithi mayelana 100 litre amanzi ngamunye. Amanzi kufanele njalo uyogcwala oksijini pool kufanele isungulwe exchange yayo. Okuphakelayo izibungu isidingo Artemia decapsulated noma Tubifex. A kamuva Ukudla ngesonto iqondiswa kokuqala okuphakelayo. I ukukhanyisa kufanele kube engakhanyi noma kusihlwa.

Lezi ziphungumangathi zasondela kuhluke ubuzimu, ngakho ekupheleni esigabeni sokuqala ngendlela yemvelo okuqukethwe gazinga kwehle kumayunithi 25-50 ilitha lamanzi ngalinye. Hlunga ongumdobi isidingo esizayo ngesonto lesithathu. nokugxambukela ungase ungazithukuthelisi izibungu, ngakho ekuhlungeni kufanele kwenziwe ngokucophelela. Ngemva kwalokho, izinhlanzi ihora kwesokunxele in ikhambi antibiotic.

Isigaba sesibili sihlala 5 amasonto. Ngokuvamile, lokhu mjikelezo uqala nge echibini egcwele izibungu ihlelwa kahle. Isibalo sawo kufanele kube ok. 300-500 mg. Izibungu kumele alungise zibe izingxenye 2 ubukhulu.

Ngokuvamile Fry eyikati Afrika ihlala phansi, kucatshangelwa isisindo ezithile izinhlanzi kanye ivolumu wechibi. Ukudla nsuku zonke, ihlukaniswe 3 ukudla, kufanele kube cishe 5% ngesisindo sezinti izinhlanzi.

Isigaba esilandelayo cishe izinyanga ezimbili. Fish esikhathini 130-200 gr kufanele acabangisise. fingerling ukukhula rate incike kwabantu lokutshala. Ukuze amachibi ayizinkulungwane 5. Amalitha zokutshala konga 2.5 izicucu ilitha. lokushisa kwamanzi uhla degrees 27.

Esigabeni wesithathu ukudla esiyinhloko eyikati Afrika - elintantayo. inqubo Yokudla - okuzenzakalelayo noma mathupha. Amanzi kufanele ishintshwe emva 2 h.

kulinywe

Growing eyikati Afrika ngaphambi isethulo kuthatha cishe 50 izinsuku kusukela ngosuku beqeda lwesithathu izibungu esiteji ukukhulisa. Isisindo esivamile izinhlanzi kuya ekupheleni yonke inqubo kungathatha kufika 2 amakhilogramu. Phakathi nale nkathi, i-eyikati Afrika Itholakala imicengezi namandla-10 cubic ngamasentimitha. At ezimbili amalitha amanzi itshalwe hhayi ningi than 3 izinhlanzi. Le ndlela kunikeza 400 khilogremu izinhlanzi bukhoma ngalinye imitha cubic yamanzi.

Iningi ngokuvamile fed izinhlanzi ngalesi okuphakelayo elintantayo esiteji. Umthamo ukudla imayelana 3% we isisindo sezinhlanzi. Okuphakelayo kudingeka wakhe mayelana 5 izikhathi ngosuku.

Imiphumela Excellent bungatholakala uma usebenzisa Element "Reflex". A Element yalolu hlobo lisetshenzisiwe 10 izigcawu endaweni pool.

yokudla Manual oluqinisekisa ngaphezulu ngisho sokwaba ukudla. Lokhu kuholela kwamangqamuzana nenqwaba izinhlanzi. Afrika eyikati zizalela ukuthi kwenzeka ngendlela elawulwa, sikhombisa abalulekile kwesisindo esikhathini esifushane yesikhathi.

Ngemva kokuphothulwa zonke izigaba izinhlanzi ihlelwa. Yabonisa izinga best of isisindo somzimba kanye nokukhula abantu ishiywa yokuzalanisa okwengeziwe, lonke izinhlanzi uthunyelwa lezo zinhlelo. Pools futhi emathileyi ngemva kokukhulisa izinhlanzi wageza futhi bahlanza kuze isizukulwane esilandelayo. Ngaphambi kokusebenzisa entsha ziphathwe isixazululo isinqandakuvunda.

Banikezwe kuqhathaniswa okusezingeni eliphezulu lokushisa lamanzi ukuzalela eyikati Afrika kungenzeka kuphela eningizimu yeRussia. Njengamanje sizibandakanye ezifanelekayo ukufuya eyikati ku Temryuk isifunda Krasnodar Territory.
