Temo e tsitsitseng ea Carp le RAS: Ho Ntlafatsa Tšebeliso ea Metsi le Bophelo bo Botle ba Litlhapi

Mathata a Temo ea Carp Kajeno

Temo ea Carp e ntse e le karolo ea bohlokoa temong ea metsing lefatšeng ka bophara, haholo Asia le Europe Bochabela. Leha ho le joalo, mekhoa e tloaelehileng e thehiloeng matangoaneng e atisa ho tobana le mathata a kang tšilafalo ea metsi, taolo e fokolang ea mafu, le tšebeliso e fosahetseng ea mehloli. Ka tlhokahalo e ntseng e eketseha ea litharollo tse tsitsitseng le tse ka senyehang, Recirculating Aquaculture Systems (RAS) e fetoha khetho e ntseng e eketseha bakeng sa mesebetsi ea sejoale-joale ea temo ea carp.

RAS ke Eng?

RAS (Recirculating Aquaculture System)ke tsamaiso ea temo ea litlhapi e thehiloeng mobung e sebelisang metsi hape ka mor'a ho hloekisa ka mechine le ea likokoana-hloko, e leng se etsang hore e be tharollo e sebetsang hantle haholo le e laoloang. RAS e tloaelehileng e kenyelletsa:

√ Sefe ea Mechini:E tlosa lintho tse tiileng tse fanyehiloeng le litšila tsa litlhapi
√Tlhophiso ea Likokoana-hloko:E fetola ammonia le nitrite tse kotsi hore e be li-nitrate tse nang le chefo e fokolang
√Aeration le Degassing:E netefatsa maemo a lekaneng a oksijene ha o ntse o tlosa CO₂
√Ho bolaea likokoana-hloko:Phekolo ea UV kapa ozone ho fokotsa kotsi ea mafu
√Taolo ea Mocheso:E boloka mocheso oa metsi o le boemong bo loketseng bakeng sa kholo ea litlhapi

Ka ho boloka boleng bo nepahetseng ba metsi, RAS e lumella ho boloka setoko se phahameng, kotsi e tlase ea mafu, le ho fokotsa tšebeliso ea metsi, e leng se etsang hore e be se loketseng bakeng sa temo ea carp e tsitsitseng.

Litlhoko tsa RAS bakeng sa Temo ea Carp

Carp ke litlhapi tse tsitsitseng, empa temo e matla e atlehileng e ntse e itšetlehile ka boleng bo tsitsitseng ba metsi. Setupong sa RAS, lintlha tse latelang li bohlokoa haholo:

√Mocheso oa Metsi:Ka kakaretso 20–28°C bakeng sa kgolo e nepahetseng
√Oksijene e Qholotsoeng:E tlameha ho bolokoa maemong a lekaneng bakeng sa phepo e sebetsang le metabolism
√Taolo ea Ammonia le Nitrite:Carp e na le kutloelo-bohloko ho metsoako e chefo ea naetrojene
√Moralo oa Tanka le Sisteme:E lokela ho nahana ka boits'oaro bo mafolofolo ba ho sesa le moroalo oa biomass oa carp

Ka lebaka la potoloho ea bona e telele ea ho hola le biomass e phahameng, temo ea carp e hloka lisebelisoa tse tšepahalang le taolo e nepahetseng ea seretse.

Thepa e khothalelitsoeng ea RAS bakeng sa Carp Aquaculture

Holly Technology e fana ka lisebelisoa tse fapaneng tse etselitsoeng lits'ebetso tsa RAS temong ea carp:

• Li-Microfilters tsa Pond:Ho tlosa lintho tse thata tse emisitsoeng hantle le lijo tse sa jeoang

• Mecha ea litaba ea bophelo (Biofillers):E fana ka sebaka se seholo sa holim'a libaktheria tsa nitrifying

• Li-Bubble Diffuser le Li-Air Blowers tse ntle:Ho boloka oksijene le phallo e nepahetseng

• Ho ntša metsi a Sludge (Screw Press):E fokotsa metsi a litšila 'me e nolofatsa ho lahla

• Lijenereithara tse nyane tsa Bubble:Ntlafatsa phetisetso ea khase le ho hlaka ha metsi lits'ebetsong tse phahameng haholo

Litsamaiso tsohle li ka etsoa ka mokhoa o ikhethileng ho fihlela litlhoko tse khethehileng tsa polasi ea carp, ebang ke bakeng sa ho qhotsoa kapa ho hōla.

Qetello

RAS e emela tharollo e matla bakeng sa temo ea sejoale-joale ea carp, e sebetsanang le mathata a tikoloho, moruo le ts'ebetso. Ka ho kopanya mekhoa e metle ea ho hloekisa le ho hloekisa metsi, lihoai li ka fumana chai e ntle ka lisebelisoa tse fokolang.

Haeba u rera ho ntlafatsa ts'ebetso ea hau ea carp aquaculture, re mona ho tla u thusa. Ikopanye le rona kajeno ho ithuta haholoanyane mabapi le hore na litharollo tsa rona tsa RAS li ka tšehetsa katleho ea hau ea temo ea litlhapi joang.
