Okuqukethwe
Ukuzalanisa kungenye yezikhathi ezibaluleke kakhulu ekuphileni kwanoma iyiphi inhlanzi, umuntu ngamunye uvame ukushiya ngemuva inzalo. Ukuzala kwe-pike kuyathakazelisa impela, ukuziphatha kwesilwane esizingelayo ngalesi sikhathi akujwayelekile kakhulu. Umdobi uphoqelekile nje ukuthi azi zonke izingqinamba zenqubo, lokhu kuzomvumela ukuba abe nezinhlanzi futhi angaweqi umthetho.
Kuyini ukuzala futhi kwenzeka nini
I-Spawning yinqubo yokubekela amaqanda ezakhamuzini ze-reservoir, okungukuthi ezinhlanzi. I-ichthyoger ngayinye lapho iqala ukuthomba ilandela imizwa yayo engokwemvelo, futhi ihlanganisa ukuzala.
Kunzima ukusho ngokuqondile ukuthi i-pike spawning iqala nini, le nqubo ithonywa izimo zezulu, futhi ubudala besifazane kufanele bucatshangelwe. Ngokuvamile iqala ukuzala kuqala endaweni yamanzi, futhi intsha ikwenza ngokushesha, abantu abadala baqedela inqubo. Ngesikhathi sokushintshwa kwe-fry endleleni yokuphila edlayo, ukuzala kusanda kuqala kuzo zonke ezinye izilwane, ngakho-ke azihlali zilambile.
Ukuzala kubonakala ngezigaba ezintathu:
| Isigaba | izici |
| pre-spawning zhor | kungakhathaliseki izimo zezulu, umhlaseli udonsa yonke into esendleleni yawo ngaphansi kweqhwa nasemanzini avulekile |
| Roe | inhlanzi ayidli nhlobo, iya ezindaweni ezibhekwe ngaphambili zokubekela amaqanda |
| emva kokuzala zhor | ngemva kokugula kancane ngemva kwenqubo eyinkimbinkimbi, i-pike ibuyisela isimo sayo, idla ngenkuthalo izidalwa eziphilayo ezivela endaweni yokugcina amanzi. |
Uma ubusika budonsa, inqubo ingenzeka ngisho nangaphansi kweqhwa.
Esinye isici ukuthi kuma-reservoirs avaliwe inqubo yenzeka ngaphambi kwesikhathi. I-pike ihamba nini ukuyozalela emifuleni? Ngokuvamile amaviki angu-3-4 ngemva kwezihlobo zabo zechibi kanye nechibi.
I-pike izala ineminyaka emingaki
Ukuze kusetshenziswe ngempumelelo inqubo, kuyadingeka ukuthi amanzi afudumale aze afike ku-3-7 degrees Celsius, kuphela lapho umhlali wezinyosi uzokwazi ukwenza konke ngendlela engcono kakhulu. Akuwona wonke umuntu ongashiya inzalo ngisho nangaphansi kwezimo ezifanele; izinhlanzi kumele zibe sezivuthiwe ngokocansi. Echibini ngalinye lingumuntu ngamunye, kodwa imithetho ejwayelekile imi kanje:
- insikazi iyakwazi ukubeka amaqanda lapho ineminyaka engu-4 ubudala;
- owesilisa uthathwa njengovuthiwe ngokocansi entwasahlobo yesihlanu.
Ngokudla okunempilo kanye nezimo ezinhle kakhulu endaweni yamanzi, abesifazane bazokwazi ukukhiqiza inzalo phakathi neminyaka emi-3 emva kokuzalwa.
Umuntu ovuthiwe ukala okungenani ama-400 g.
I-pike izobeka amaqanda amaningi kakhulu njalo ngonyaka, isibindi eside siyakwazi ukushiya amaqanda angama-220 ngesikhathi. Ngaphambi kokuqala, abantu baphambuka ngamaqembu, kowesifazane ngamunye kukhona abesilisa abangu-000-3. Ama-Cavaliers aphelezela le ntokazi lapho eya khona, inombolo yabo incike kubukhulu bezinyo, uma ikhudlwana, abesilisa abaningi bayayiphelezela.
Lapho ukuzala khona
Lapho i-pike izala, iqala futhi iphetha le nqubo, bathole. Kufanele kuqashelwe izindawo, ngoba zibaluleke kakhulu ekongiweni kwabantu.
Enzalweni, umhlaseli ukhetha amanzi angashoni, ngoba amanzi lapho afudumala ngokushesha nangcono. Izinketho ezinhle kakhulu yilezi:
- imifula emincane;
- imifudlana;
- amarimu;
- kwemboni
Izici eziyinhloko zale ndawo ukujula okungajulile kuze kufike kumitha kanye nokuba khona kwamatshe, izihlahla, utshani, ama-snags ngaphansi kwamanzi. Yibo abazosiza izinhlanzi ukuqeda ubunzima esiswini, okungukuthi, amaqanda azokhululwa. Lapho i-pike izala, ivele ihlikihle zonke izithiyo ezingaphansi kwamanzi, njengokungathi ikhipha inzalo ngokwayo.
Lapho i-pike isanda kuqala ukuzala, abesilisa baseduze, kodwa ekupheleni kwenqubo, kungcono ukuba bahlale kude nowesifazane olambile. Abadobi babevame ukubuka isithombe sokudla isihlobo nowesifazane ezindaweni zokuzalela.
Esikhathini esizayo, umhlaseli awuhambi kude, ngaleyo ndlela uvikele inzalo yakhe ku-roach ne-perch, ekhonza i-caviar yayo. Yebo, futhi kuzoba khona okuzodliwa lapha, okulandelwa ukuzala kwe-roach.
Izici zokudoba ngesikhathi sokuzala
Ezifundeni eziningi, ukudoba akuvunyelwe noma kukhawulelwe ngesikhathi sokuzala, lokhu kufanele kubhekwe ngaphambi kokuthi uyobamba. Kunqatshelwe ngokuphelele ngumthetho:
- zungeza ichibi ngezikebhe ezigwedlayo nasezikebheni zamanzi ngenjini;
- sondela ogwini ngemoto nemoto eduze kwamamitha angama-200;
- izindawo zokuzalanisa.
Umthetho ongashiwongo ukubuya komhlali we-toothy nge-caviar emanzini, kungcono ukulinda amasonto ambalwa bese ubuyela lapha futhi.
Ngokushesha ngemva kwenqubo, umhlaseli uyayeka ukuphendula kunoma iyiphi i-bait, ayisebenzi futhi empeleni ayinyakazi. I-pike igula kangakanani ngokushesha ngemva kokuzala kwentwasahlobo? Ukuze alulame, udinga amasonto angu-2-3, umdobi uzokwazi ukuthola ngalokhu echibini. Uzothatha ngenkuthalo yonke i-bait enikezwayo, ezama ukulungisa lokho okushodayo esiswini sakhe.
Inkambo evamile yokuzala ibaluleke kakhulu ekugcineni inani lezinhlanzi emanzini, kokubili okuvaliwe nokuvulekile. Kuyafaneleka ukubheka umthetho futhi sigweme ukubamba izibonelo ze-trophy phakathi nalesi sikhathi, khona-ke inani lama-pike lizokwanda kuphela, ukuze sijabule sonke.
