Ukulima kweCarp okuZinzileyo kunye ne-RAS: Ukuphucula ukusebenza kakuhle kwamanzi kunye neMpilo yeeNtlanzi

Imingeni ekuLimeni kweeCarp namhlanje

Ukulinywa kweCarp kuhlala kulicandelo elibalulekileyo kwi-aquaculture yehlabathi, ngakumbi kwi-Asia naseMpuma Yurophu. Nangona kunjalo, iinkqubo zemveli ezisekwe emachibini zihlala zijongene nemingeni efana nongcoliseko lwamanzi, ulawulo olulambathayo lwezifo, kunye nokungasebenzi kakuhle kobutyebi. Ngokunyuka kwemfuno yezisombululo ezizinzileyo nezinokwehla, iRecirculating Aquaculture Systems (RAS) iya isiba lukhetho oluthandwa kakhulu kwimisebenzi yanamhlanje yokulima icarp.

Yintoni iRAS?

I-RAS (iRecirculating Aquaculture System)yinkqubo yokulima intlanzi esekwe emhlabeni ephinda isebenzise amanzi emva kokuhluzwa ngoomatshini kunye nebhayoloji, oko kuyenza ibe sisisombululo esisebenza kakuhle samanzi kwaye siyalawuleka. I-RAS eqhelekileyo ibandakanya:

√ Uhluzo loomatshini:Isusa izinto eziqinileyo ezimisiweyo kunye nenkunkuma yeentlanzi
√Uhluzo lwebhayoloji:Iguqula i-ammonia enobungozi kunye ne-nitrites ibe yi-nitrates enetyhefu encinci
√I-Aeration kunye ne-Degassing:Uqinisekisa amanqanaba aneleyo e-oksijini ngelixa ususa i-CO₂
√Ukubulala iintsholongwane:Unyango lwe-UV okanye i-ozone ukunciphisa ingozi yesifo
√Ulawulo lobushushu:Igcina ubushushu bamanzi bukwiqondo eliphezulu ekukhuleni kwentlanzi

Ngokugcina umgangatho ophezulu wamanzi, i-RAS ivumela ukuxinana okuphezulu kwempahla, umngcipheko wesifo esisezantsi, kunye nokunciphisa ukusetyenziswa kwamanzi, okwenza kube yinto efanelekileyo yokulima i-carp ezinzileyo.

Iimfuno ze-RAS zoLimo lweCarp

ICarp ziintlanzi ezikwaziyo ukumelana namanzi, kodwa impumelelo yokulima ngamandla isaxhomekeke kumgangatho wamanzi ozinzile. Kuseto lwe-RAS, ezi zinto zilandelayo zibaluleke kakhulu:

√Ubushushu baManzi:Ngokubanzi ngama-20–28°C ukwenzela ukukhula okugqibeleleyo
√Ioksijeni Enyibilikisiweyo:Kufuneka igcinwe kumanqanaba aneleyo okutya okusebenzayo kunye nemetabolism
√Ulawulo lwe-Amoniya kunye neNitrate:ICarp inovelwano kwimixube yenitrogen enetyhefu
√ITanki kunye noYilo lweNkqubo:Kufuneka uqwalasele ukuziphatha okusebenzayo kokuqubha kunye nomthwalo we-biomass we-carp

Ngokunikwa umjikelo wabo wokukhula omde kunye ne-biomass ephezulu, ukulima kwecarp kufuna izixhobo ezithembekileyo kunye nolawulo olululo lodaka.

ISixhobo se-RAS esicetyiswayo seCarp Aquaculture

ITekhnoloji yeHolly ibonelela ngoluhlu lwezixhobo ezilungiselelwe izicelo ze-RAS kulimo lwecarp:

• Izihluzi zePond Micro:Ukususwa okusebenzayo kwezinto eziqinileyo ezimisiweyo kunye nokutya okungatyiwanga

• Imidiya yebhayoloji (Izihluzi zebhayoloji):Ibonelela ngommandla omkhulu womphezulu webhaktiriya ene-nitrifying

• Izahluli zeBubble eziLungileyo kunye neZivutheli zoMoya:Gcina i-oxygenation efanelekileyo kunye nokujikeleza

• Ukukhupha amanzi kwi-Sludge (Screw Press):Yehlisa isiqulatho samanzi kwi-sludge kwaye yenza lula ukulahla

• Iijenereyitha zebhabhula ezincinci:Ukuphucula ukuhanjiswa kwegesi kunye nokucaca kwamanzi kwiinkqubo zoxinaniso oluphezulu

Zonke iisistim zinokulungiswa ukuhlangabezana nomthamo okhethekileyo kunye neemfuno zoyilo kwifama yakho ye-carp, nokuba yeyokuqandusela okanye izigaba zokukhula.

Ukuqukumbela

I-RAS imele isisombululo esinamandla sokulima i-carp yanamhlanje, ukujongana nemingeni yokusingqongileyo, uqoqosho, kunye nokusebenza. Ngokudibanisa ukusebenza okuphezulu kokucoca kunye nobuchwepheshe bokucocwa kwamanzi, amafama angakwazi ukufumana izivuno ezingcono kunye nezixhobo ezimbalwa.

Ukuba uceba ukuphucula imisebenzi yakho ye-carp aquaculture, silapha ukukunceda. Qhagamshelana nathi namhlanje ukuze ufunde ngakumbi malunga nendlela izisombululo zethu ze-RAS ezinokuxhasa ngayo impumelelo yakho yokufuya iintlanzi.
