Kubereka uye kukura crayfish pamba hakusi isiri uye kwave kuchiitwa kwenguva yakareba. Misiyano iyi ndeyekuyera: ndeye bhizinesi iri, uye ndiani anozviita nokuda kwekuda kwavo.
Nzvimbo yekudyara kwekudya
Pamakwenzi ekuberekesa unogona kushandisa zvose zviri mumvura uye mvura yakadzika. Vamwe vanoronga matangi akazara. Kuti uise aquariums iwe uchada kamuri rakanaka kupisa. Uye mukati memahombekombe, ronga matombo akavhara nemiti yemvura. Kumanikidzwa kusvina mafaira uye air compressors .
Dziva racho rinogadzirirwa mugomba rakagadzirirwa zvakagadzirirwa nepo polypropylene ndiro. A pneumatic compressor inobereka aeration. Mumadziva ekugezera anowanzo akura kubva mazai eagoago.
Ichokwadi, nokuda kwekuberekwa kwekuita kwechirwere chekenza yakawanda iwe uchada chigadziro chegungwa, icho chakanaka kana iwe uine nzvimbo huru isina nzvimbo. Kana kukwirira kwebhesheni hakuwanzopfuura 70 masentimita, dziva rinofanira kunge rine mamita maviri. Uye nzvimbo yacho haisisiri 2 mamita matanhatu, asi 0.3 mahekita. Kuti mvura haisi kusiya dziva, pasi rayo inofanira kuvharwa nefirimu isina mvura. Asi panguva imwechete iyo inofanirwa kuitisa mapaipi maviri - mvura yekudonhera uye yekupa mvura yakachena. Munzvimbo yakadzika iwe unofanirwa kuisa michero yemvura, uye kuwedzera gungwa nemiti uye shrub.
Kuti uitange kubereka crayfish, zvinokosha kusarudza zvepabonde vanhu vakakura, avo vane makore 4-5. Zvinonyatsozivikanwa kuti kana crayfish ikachengetwa zvakakodzera, inogona kurarama kusvika makore makumi maviri nemashanu, uye imwe musikana inogona kukupa kusvika kune makumi matatu e-crayfish mukati megore rimwechete.
Mitero yekenza uye nzira dzekuzvara
Dilution uye kuchengetedza krayfish zvinofanira kuitika mumvura yakachena. Ivo vanonyanya kunyanya pakuwa. Uye mukati megore iwe unogona kuona maitiro maduku emakristace anowanikwa kubva mazai.
Kunyange zvazvo uri pamba, kana iwe uri kubereka mbeu yakakosha, chirongwa chekuzadza mazai chinogona kuwedzerwa uye kupfupika kusvika kumwedzi mitatu. Ichando chemvura yemhuka yemvura haifaniri kudarika madigiri makumi maviri nemana. Basa rezvipfuwo rinoratidzwa usiku, panguva yemasikati vanorara zvakanyanya mumisha yavo.
Idya zvimedu zvekrayfish dzinoda mvura yakachena yemvura, shellfish, ropaworms, zvipembenene, zvitunha zvehove, zvipembenene zvepasi, pamwe nematatya. Vanhu vakura vanodya zvikuru mumwaka wekushisa, uye munguva yechando vanobva vanyarara, hafu yehope, uye zvinoenderana, idya zvishoma.
Kana kushambadzira kwekrayfish kunowanikwa mumvura yakadzika kana masango emvura, uko kutonhorera kwemvura kusingadonhe pasi pedhigirii 15, unofanirwa kufudza crayfish gore rese. Madzimai ane mazai akadyarwa mugomba chete kana mvura ichikwira kusvika kune madigiri makumi maviri. Zvakakosha kutarisa chitarisiko chemadzimai emangwana - kana vane mhombwe pamuromo uye zvipfeko zvinoderedzwa, zvinodyarwa mune rimwe dziva rega, uko kushanduka kwemvura kunoitika paanenge 0.6 - 0.7 l / min.
Apo mheta inoputika kubva mazai inova yakasununguka, vakadzi vanodyarwa mugomba uko vangave vatokwanisa kudururwa uye, zvichida, vakaroorana nevarume kuti varambe vari vana. Rusununguko rwemapuranga runogona kugadziriswa nekuti ivo vanorega kuunganidza murwi, musavanze munguva yengozi pasi pemuswe waamai, uye vanofambira nokukurumidza vachitsvaga zvokudya pasi peimba yavo.
Mushure mokunge vasvika muzera reSagolets - mazuva makumi mapfumbamwe, vanogona kuendeswa kune dziva kuitira kuti varambe vachikura nekukura mumamiriro ezvinhu epanyama.
Kuberekwa kwekenza yebhuruu yeCuban, iyo inofarira kunge iri chiedza kwemaawa anenge gumi, uyewo inowanika pamiti yemvura, iri nyore. Vanodya nenzira yakafanana nedzimwewo crayfish, chete zvokudya zvinofanira kuva mumvura yakadzika maawa 24 pazuva. Inobereka gore rose. Uye nguva yekuchera mazai mazhizha pamvura inopisa ye 26-27 degrees inoitika mumavhiki matatu.
