Fish-gqith: eziluncedo phezu iifomu ehlambulukileyo. Ukusetyenziswa hybridization

Kunye neentlobo olusulungekileyo namhlanje yokusetyenziswa likhulu aquaculture nentlanzi-gqith. Kubalulekile ixabiso elikhulu ngenxa yomsebenzi wabo efuna ukutya, ukukhula ngokukhawuleza kunye nozinzo kwizifo ezininzi.

hybridization fish

Kwindalo kukho wambi ukunqumla iintlobo ngeentlobo zeentlanzi ngokwendalo. Nangona kunjalo, ezi ngxilimbela azinazo iimpawu eziyimfuneko lomntu. Lwenziwa ngoososayensi kunye abalimi ukuba ukusebenza kunye nokugcina imithetho ethile ivelise uhlobo olutsha ntlanzi, okuye eziluncedo ezininzi phezu iintlobo ehlambulukileyo.

Ekuqaleni izinto ukunqumla kakhulu lentsapho Cyprinidae, ngoko kukho intlanzi - Intlanzi gqith kunye Intlanzi, sturgeon, etc ...

hybridization Intsingiselo

Kwiminyaka yakutshanje, ngenxa yokwanda amanzi, kukho utshintsho ulawulo amanzi imilambo, nto leyo ekhokelela ukuhla kwimiphakathi iintlanzi ezithile, ingakumbi sturgeon. Kule meko, i hybridization kubaluleke kakhulu ukuba yolondolozo yeentlobo zezidalwa zexabiso. Le ngxilimbela kuphumela lwemfuyo Intlanzi abe nempumelelo ephezulu kunye nokukhula ngokukhawuleza. Oku kwenza ezizalayo mveliso inzuzo, ukuvumela ukufumana iintlanzi high quality emva amaxesha 2-3 kuphela ikhula.

Yenza iintlobo ezintsha singapheli kunye nemveliso ukwenzela ukuba zisetyenziswe zokulima iintlanzi kula manzi, imiqathango ongayi kunikwa ingqalelo ezithandwa intlanzi iindlela lobuhlobo. ngcono kakhulu Bona apha naphaya ukulungiselela iimeko ezintsha. Umzekelo, isipili zeCARP kunye zeCARP Amur kwi iminqamlezo zaba inzala ukuba hardiness eliphezulu. Isibakala sokuba ibhastile amanqatha oqokelela ngokukhawuleza kakhulu, ngoko ke wabunyamezela abandayo lula kakhulu. Ngenxa yokukhula ngokukhawuleza nokuqalisa kobusika, ukuhluma sele kakhulu kwaye kumhlangabeza sele zibethelelwe yayo. Fish-hybrid, ngokungafaniyo uhlobo ecocekileyo, aphile kwaye ukukhula amadama kude emntla.

hybrids zeCARP Common

Eyona umdla ke hybrid zeCARP kunye zeCARP crucian. Le intlanzi ezomeleleyo kwaye ngaphantsi sifo sisifo ngaphezu zeCARP, elikhulayo ngokukhawuleza kakhulu kwaye filet esimnandi kakhulu, nto leyo ifana umgangatho iintlanzi umtya iintlobo ehlambulukileyo.

Zidala izikhokeli ingqamana c yokuzala xesha ezinye iintlanzi. Oku kudla ngokwenzeka ngoMeyi noJuni. Ngeli xesha, abantu basoloko zibuko of zeCARP crucian. Iifom omtsha Kuphela zifumaneka abanayo umgangatho efunekayo.

Hybrid zeCARP kunye zeCARP Dnieper wadala ngenjongo yokuzalela iintlanzi emasimini, ubunzulu nto leyo alanelanga ukuba zeCARP eqhelekileyo, kunye back eliphezulu. Inzalo ilifa umva zeCARP ephantsi, kunye neemeko abahlala kubo emasimini baphatheka evumayo. zeCARP Hybrid kunye zeCARP zikwalungiselelwe ukuba ubomi kwimimandla esemantla, njengoko amaqanda uqhotse baye ilifa ukumelana zeCARP kumaqondo obushushu aphantsi.

Xa amanzi zasemaphandleni ngenxa ukuchuma eliphezulu hybrid zeCARP ixhaphakileyo. Udla ithatha zeCARP kunye nezinye iintlanzi.

kwaqanjwa sturgeon

Kakhulu nempumelelo eliphezulu wabonisa gqith yakhulela yi abalimi ngo-1950 ngokuthi awela kunye sturgeon sterlet. Malunga 180 kg ubunzima bakhe bafika emva kweenyanga ezili-10.

Dolphin, ukuba iintlanzi inkulu sturgeon, Intlanzi nendlela lincinci zivelise uhlobo olutsha ogama Bester. Ukuba iimpawu ngesakhiwo lomzimba ubunzima iintlanzi Intlanzi gqith zikhuliswa kakhulu ngempumelelo kumanzi acocekileyo. Kuba ixesha lokuqala olu hlobo sele ifunyenwe eRashiya ngowe-1952 yaye yaqaliswa ngo uyazazi Reservoir kunye eLwandle Azov. Bester wavuka ezininzi iimpawu ilungileyo ukutya kunye sterlet kuyo ilifa inyama nencasa kwaye okunesondlo. Xa ndandineminyaka emithathu, le hybrid ufikelela ubunzima ka-3 kg.

Uninzi dama, apho ngokuthe ukunxibelelana iintlobo Intlanzi aphel, ngenxa hybridization ufumene ifomu entsha iintlanzi ngokuwela spike kunye stellate sturgeon. Le hybrid ukukhathaza ukuya kwi-30 kg ekhulisa ngokukhawuleza kakhulu iifom ngabazali. izilwanyana Abaselula nokomelela efanayo idlula zonke ezinye iintlobo sturgeon. Namhlanje, le ntlanzi-gqith kwi ophakathi iVolga ezilinywa amaninzi okuloba.

Terms sturgeon hybridization

Zokulinywa ngempumelelo ibhastile Intlanzi efunekayo ukuthobela imiqathango ethile. Le ntlanzi ongayithandiyo emanzini, ngoko ubunzulu kufuneka ebonakalayo. Kufuneka kwakhona babe emanzini utyani kakhulu, filaria ingakumbi kunganqwenelekiyo ukuba zenzeke, nto leyo maxa wambi amachibi ayegqunyelelwe njengoko iintlanzi babanjwa kuyo. Amachibi kunye ndee anodaka ayifanelekanga ukuba isetyenziselwe sturgeon, kuba ngokuqhelekileyo abondliwayo ukuya kumphezulu ezantsi.

Ukuze ukuphelisa ukhuphiswano nokutya, kucetyiswa ukuba ungazizekisi Intlanzi neentlobo herbivorous, ezifana, ngokomzekelo, njengoko zeCARP isilivere zeCARP ingca. Fish-gqith kufuneka isasazwe phezu amanzi, kuthathelwa ingqalelo ubungakanani kunye nobudala, ngenxa yokuba kaninzi ukudla mbelukazi abaselula abadala.

nobubi hybridization

Ukukhulisa ibhastile nto ifuna iimeko zivuma. Ukuphambuka incinane kwezi mfuno kunokukhokelela iziphene isakhiwo ukakayi okanye operculum. Ngokudla zaneleyo ngexesha zinemimoya xa amachibi kunye ndee anodaka kukho iziphene ezahlukeneyo, kunye nezinye iparameters ezininzi.

Kubalulekile yindlela ukunqumla. Ngokomzekelo, xa caviar zeCARP aqhamileyo zeCARP milt, iphumelele iziphumo ezintle hardiness gqith. Kodwa xa ziyazalana eveliswe, ukuchumisa amaqanda zeCARP, propati engenakufunyanwa.
