Izici nendawo yokuhlala ye-carp yesiliva
Ensimini yamazwe e-CIS, ungabona izinhlobo ezintathu zezinhlobo i-carp yesiliva: emhlophe, i-variegated ne-hybrid. Abamele lolu hlobo bathola igama labo, ubukhulu becala, ngenxa yokubukeka kwabo ngokwemvelo.
Ngakho-ke, umhlophe i-carp yesiliva esithombeni nasempilweni umthunzi omncane. Isici esiyinhloko esihlukanisa le nhlanzi yikhono eliyingqayizivele lokuhlanza amadamu angcolisiwe avela ezinsaleleni zezinto eziphilayo, uhlaza oluningi, njll.
Yingakho ke i-carp yesiliva Zingeniswa emachibini angcolile, lapho ukudoba kunqatshelwe khona isikhashana - izinhlanzi zidinga isikhathi sokususa echibini. Lolu hlobo luthola isisindo kancane kancane.
Kuboniswe i-carp yesiliva
I-carp yesiliva inomthunzi omnyama, futhi isici sayo esiyinhloko ukukhula kwayo ngokushesha. Abamele lolu hlobo badla i-zooplankton ne-phytoplankton futhi kungenxa yenani lokudla abakudlayo okwenza zikhule ngokushesha okukhulu.
Esithombeni kukhona ukhakhayi wesiliva onemishwe
I-carp hybrid yesiliva, njengoba igama lisho, iyinhlanganisela yezinhlobo ezimbili ezichazwe ngenhla. I-hybrid inombala okhanyayo wokhokho abamhlophe nokuthambekela ekukhuleni okusheshayo kwe-variegated. Zonke lezi zinhlobo zidliwa ngabantu, ngakho-ke ungathenga i-carp yesiliva kunoma yisiphi isitolo sezinhlanzi. Eminyakeni edlule yokusebenzisa izinhlanzi ngale ndlela, izindlela eziningi ezahlukahlukene zokulungiselela ukhaphethi wesiliva zivele.
Ukuqala ngokujwayelekile isobho le-carp fish, iphetha ngezindlela ezinhle zokupheka izitho zomzimba ngamunye, ngakho-ke, ikhanda le-carp yesiliva kubhekwe njengesibiliboco. Abamele abakhulu bezinhlobo bangafinyelela ubude bemitha futhi babe nesisindo esingama-50 kilograms.
Kuboniswe i-carp yesiliva e-hybrid
Ekuqaleni, izigaxa zesiliva zazitholakala eChina kuphela, kepha, ngenxa yezindawo zabo eziwusizo, umsebenzi wenziwa ekuqhelaniseni nasekuhlaliseni kabusha eRussia. Njengamanje, ama-carps esiliva angahlala cishe kunoma yimuphi umfula, echibini, echibini, into esemqoka ukuthi ukugeleza akusheshi kakhulu, futhi namanzi awabandi kakhulu.
Ekwindla i-carp yesiliva sondela ogwini bese ugcwala emanzini angajulile phansi kwelanga. Bese kuthi, kanye nokugeleza kwamanzi afudumele, bathuthele emazibeni. Ngaphezu kwalokho, ama-carp esiliva angahlala eduze kwezakhiwo zobuchwepheshe zabantu abafudumeza amanzi ngokungeyikho. Isibonelo, eduze kwezitshalo zamandla ezikhipha amanzi afudumele emizimbeni yamanzi.
Imvelo nendlela yokuphila ye-carp yesiliva
I-Silver carp yinhlanzi ehlala ezikoleni kuphela. Ziyachuma emanzini afudumele anomsinga omncane. Uma lezi zimo kuhlangatshezwana nazo, i-carp yesiliva iyondla futhi ikhule ngokushesha. Ngokuqala kwezulu elibandayo, izinhlanzi zingenqaba ngokuphelele ukudla, ziphila ngamafutha anqwabelene. Izinhlanzi zibanjwa ngezinduku zokudoba ezansi nokuphotha.
Ngokufika kokushisa ekuqaleni kwaphakathi nentwasahlobo, i-carp yesiliva ihamba ngenkuthalo kulo lonke ichibi. Lapho-ke, lapho kufika isikhathi sokukhula okusheshayo kwezimila, zihlala endaweni eyodwa, lapho zondla khona kuze kufike ukuqala kwamakhaza. Imihlambi ye-carp yesiliva iqala ukufuna ukudla entathakusa futhi ihlanganyela kuleli bhizinisi elihehayo kuze kube mnyama.
Ebusuku, inhlanzi iyaphumula. Ukuyibamba ebumnyameni akusizi ngalutho - ngalesi sikhathi i-carp yesiliva ayenzi lutho, futhi kaningi kunalokho, isivele igcwele ngokuphelele. Le yinhlanzi enkulu futhi eqinile, okungukuthi, ukubamba i-carp yesiliva, udinga ukukhetha imishini ezomelana nomthwalo ofanele.
Isiliva carp umsoco
Abantu abasha badla kuphela i-zooplankton; ngenkathi ivuthwa, inhlanzi ishintshela ku-phytoplankton kancane kancane. Ngasikhathi sinye, iningi le-carp yabantu abadala likhetha ukudla okuxubile, iningi lokudla kuncike kulokho okusendleleni namuhla. Ngaphezu kweminyaka, ukudla futhi kuyehluka ngezinhlobo ze-carp zesiliva.
Ngakho-ke, i-carp yesiliva yanoma iluphi usayizi nobudala esikhathini esiningi izokhetha ukudla kwezitshalo. Ngesikhathi esifanayo, i-carp yesiliva izokhetha i-phytoplankton. Lapho udoba, kuyadingeka ukuthi ubheke izici zalezi zinhlobo bese ukhetha udobo ngokuya ngohlobo lomuntu ozobamba okwamanje. Ukukhethwa kwabadobi okukhethwayo ukudoba i-carp yesiliva ku-technoplankton.
Ukukhiqizwa kabusha nokulindelwa kwesikhathi sokuphila kwe-carp yesiliva
I-carp yesiliva iyinhlanzi enokuzala okuphezulu ngokweqile. Ngesikhathi esisodwa sokuzala, owesifazane angakhiqiza amaqanda angamakhulu ayizinkulungwane eziyikhulu. Vele, lokhu akusho ukuthi ezinyangeni ezimbalwa kuzovela abantu abasha abayizinkulungwane ezingamakhulu ambalwa - okuningi i-carp caviar yesiliva izodliwa yizilwane ezidliwayo, kepha, ngamaqanda amaningi kangaka, kungenzeka ukuthi inzalo yombhangqwana ngamunye izoba miningi impela.
Izimo ezithandekayo zokuqala ukuzala yizinga lokushisa lamanzi elifanele - cishe ama-degree angama-25. Ngaphezu kwalokho, ukwakhiwa kwamatshe kwenziwa emanzini anyukayo nganoma yisiphi isizathu, imvamisa ngemuva kwezimvula ezinkulu. Ngakho-ke, lapho amanzi kunamafu futhi aqukethe ukudla okuningi okungokwemvelo, ukwakhiwa kwe-carp yesiliva.
Lokhu kubonakaliswa kokunakekelwa ukuphela kokubamba iqhaza kwabazali ekudalelweni kwamaqanda amanje kanye nefry yesalp carry yesikhathi esizayo. Amanzi we-Turbid kufanele avikele amaqanda ezitheni, inani elikhulu lokudla kwezitshalo lizosebenza njengemithombo yokudla for gazinga okokuqala ngqa. Amaqanda avundisiwe asakazeka ezindaweni ezahlukahlukene, kuya ngesimo lapho ewela khona.
Ezinsukwini ezimbalwa iqanda liba yisibungu ubude obungu-5-6 wamamilimitha, osuvele wakha umlomo, izigaxa, futhi unamandla okuhamba ngokuzimela emanzini. Eminyakeni yesonto elilodwa, isibungu siyaqaphela ukuthi ekukhuleni okusheshayo okunjalo, sidinga ukondla ngenkuthalo.
Iqonde ngasogwini ibheke indawo efudumele engenawo umsinga lapho kutholakala khona inala yokudla. Lapho, i-carp encane yesiliva ichitha isikhathi esithile, iphaka futhi kancane kancane ikhuluphale. Ekupheleni kwehlobo, fed up isiliva le-carp gazinga ayisabonakali njengeqanda le-millimeter, ngesimo sayo bekuyizinyanga ezimbalwa ezedlule.
Esithombeni, isiliva le-carp gazinga
Lokhu sekuvele kucishe kwakhiwa ngokuphelele ukhaphethi wesiliva, kuncane kakhulu kuze kube manje. Yondla ngenkuthalo ukuze iphile ebusika bayo bokuqala obubandayo. Okufanayo kwenziwa ngabantu abadala abangenayo imizwelo yabazali. Ngemuva kokuzala, bayahamba bayofuna ukudla.
Ngokufika kwesimo sezulu esibandayo, cishe u-30% wesisindo esiphelele somuntu omdala ungamafutha. Itholakala kokubili enyameni nasezithunzini zangaphakathi - lena ukuphela kwendlela yokusinda ebusika, okuchithwa yizidumbu zesiliva esimeni sokundindizela okunganyakazi. Ngaphansi kwezimo ezinhle, i-carp yesiliva ingaphila iminyaka engaba ngu-20.
