Ikoranabuhanga rya Nanobubble ryahinduye imiterere y'ubworozi bw'amafi bufite ubucucike bwinshi: Igihe gishya cy'umusaruro, ubwizigame, no kurwanya indwara

Inganda z'ubworozi bw'amafi ku isi ziri mu mpinduka zikomeye kuko ari nanoIkoranabuhanga rya Bubble igaragara nk'igisubizo gihindura umukino ku bikorwa by'ubuhinzi bw'amafi bukorerwa ku bwinshi. Kubera ko abahinzi b'amafi bakomeye ku isi—Ubushinwa, Ubuhinde, Indoneziya, Vietnam na Bangladesh—bafite umusaruro urenga 80% ku isi, igitutu cyo kongera umusaruro mu gihe habungabungwa uburyo burambye nticyigeze kiba kinini cyane. Udusimba tw'amazi—umwobo wuzuyemo gazi ufite umurambararo muto urenze mikoroni imwe—turagaragara ko ari igisubizo.

Gutanga ogisijeni idasanzwe kugira ngo umusaruro ube mwinshi

Ogisijeni yashongeshejwe ni yo soko y'ubuzima bw'ubworozi bw'amafi. Ubucucike bwinshi bw'ibiryo busaba ko umwuka utangwa cyane, kandi uburyo gakondo bwo guhumeka bukunze kubura. Ariko, ibinini binini biguma mu mazi iminsi cyangwa amezi bitewe n'ingendo za Brownian, bigatuma umwuka ukwirakwira neza kurusha ibinini bisanzwe. Ubushakashatsi bwagaragaje ko ibinini binini bya ogisijeni bishobora kongera ubwinshi bwa ogisijeni yashongeshejwe inshuro zirenze enye—kuva kuri 7.7 mg/L kugeza kuri 32 mg/L mu minota 30 gusa uhereye igihe bikorewe.

Ibisubizo biravuga ibyabyo. Muri sisitemu ya tilapia biofloc, ikoranabuhanga rya nano-oxygen bubble ryongereye umusaruro w'amafi ku kigero cya 18.8% ndetse n'urugero rwa ogisijeni yashongeshejwe neza ku kigero cya 9.22%. Ifi zo mu bwoko bwa Aziya Redtail Catfish zororewe hamwe na nanobubble oxygenation zagaragaje umusaruro mwiza w'iterambere, amazi meza, ndetse n'umuvuduko wo kubaho uri hejuru. Ahari igitangaje kurushaho, ikigo cy'isambaza cya RAS gikorera mu Bwongereza cyageze ku buremere bw'isambaza bungana na garama 35 mu minsi 80 gusa—aho izifite ibiro byinshi zageze kuri garama 42—zikoresheje ikoranabuhanga rya nanobubble ku bucucike bw'isambaza buri munsi ya kg 5/m³.

Gukoresha neza ingufu no kugabanya ikiguzi

Uretse kunoza umusaruro, nanoJenereta y'ibibunos zirimo kuvugurura ubukungu bw'imikorere. Urugero, sisitemu ya NanobOx ikora kuri watts 50 gusa mu gihe itanga litiro 800 ku munota kuri 7 mg/L ya ogisijeni ishongeshejwe - inyungu mu mikorere myiza ituma habaho kuzigama amafaranga menshi. Sisitemu ya nanobubble ya Moleaer yitwa Freya submersible nanobubble yagaragaje ubushobozi bwo kugabanya ikoreshwa rya ogisijeni kugeza kuri 41% no kugabanya ikoreshwa ry'ingufu zijyanye no guhumeka ogisijeni kugeza kuri 60%, itanga ogisijeni irenga kg 50 ku isaha ku kigero cyo hejuru kirenga 85%.

Umuhinzi wa salmon wo muri Noruveje, Gigante Salmon, yahisemo sisitemu ya Freya ya Moleaer nk'igisubizo cy'ibanze cyo gutanga ogisijeni nyuma y'uko gahunda y'igerageza igaragaje ko urugero rwa ogisijeni rwashongeshejwe ruhamye kurushaho. Tore Laugsand, Umuyobozi Mukuru Wungirije wa Gigante Salmon, yagize ati: "Freya yakemuye ibibazo byo gutanga ogisijeni twari duhanganye na byo mbere. Byari isi nshya kuri twe." Iyi sosiyete irateganya kongera ubushobozi bwa toni zigera ku 16.000 ku mwaka bitarenze umwaka wa 2028.

Kurwanya indwara no kugabanya ubudahangarwa bw'imiti irwanya udukoko

Ahari ikintu gishimishije cyane mu ikoranabuhanga rya nanobubble ni ubushobozi bwaryo bwo kurwanya ubudahangarwa bw’imiti irwanya udukoko (AMR)—imwe mu mbogamizi zikomeye zihura nazo mu bworozi bw’amafi bwa none. Udukoko twa ogisijeni tw’amafi twagaragaye ko twongera ubushobozi bwo gufata phage no kongera imikorere myiza yo kuvura phage. Nanone twongera ubushobozi bwo gufata antigen no gusubiza antibody mu gukingira, nk’uko byagaragajwe mu bushakashatsi ku birebana n’amazi yo mu nyanja yo muri Aziya.

Sisitemu ya NanoVac, yakozwe na AIT, ikoresha nanobubbles mu gutanga inkingo kuri tilapia, itanga ubundi buryo bwiza bwo kugabanya udukoko tudasize ibisigazwa by’imiti. Nanobubbles za ozone zagaragaje ko zigenzura neza bagiteri na virusi byandura, zongera cyane igipimo cyo kubaho kw’amafi no gutuma ubudahangarwa bw’umubiri butera imbaraga. Ubushakashatsi bwagaragaje ko ikoranabuhanga rya nanobubbles rigera ku nshuro 2.3 zo kohereza ozone mu buryo busanzwe, bigatuma hangirika antibiyotike hafi ya zose (>99%).

Gutunganya amazi yanduye no kubungabunga ibidukikije

Udupira duto ntabwo turi kunoza umusaruro gusa—kandi turimo no guhindura imicungire y’amazi yanduye mu bworozi bw’amafi. Udupira duto tw’umwuka na ozone twagaragaje ubushobozi bwo kwangiza imyanda neza. Guhuza ikoranabuhanga rya nanobubble na sisitemu zo korora amazi mu mazi (RAS) byagaragaye ko byongera ubwiza bw’amazi, byongera udukoko, kandi bikagabanya urugero rwa nitrite.

Sisitemu ya NanobOx yatumye habaho ukwiyongera guhoraho kwa Oxidation-Reduction Potential (ORP), bituma imikorere myiza ya flocculation irushaho kuba myiza mu gupima poroteyine no mu buryo bwo gutura, bituma ikoreshwa rya ozone rigabanukaho 8-10%. Ibi bigabanya ikiguzi kandi bigagabanya ingaruka ku bidukikije—ibyo bikaba ari inyungu ku bahinzi n’isi.

Iterambere ry'Isoko n'Iterambere ry'Inganda

Itsinda ry'abantu ku isi rito cyaneNano Bubble Isoko ry’ingufu zitanga umusaruro ryitezweho kwiyongera ku kigero cya 5.4% kuva mu 2025 kugeza mu 2031, bitewe n’ubwiyongere bw’abakeneye amazi meza no kongera umusaruro w’ubworozi bw’amafi. Abakinnyi bakomeye mu nganda barimo kubyibandaho. Ingano ya Three Sixty Aquaculture yakusanyije miliyoni 3.5 z’amapawundi mu nkunga ya Series A yo gucuruza ibikorwa byayo by’ubuhinzi bw’isambaza hakoreshejwe ikoranabuhanga rya nanobubble, mu gihe Moleaer ivuga ko ifite amagana y’ibigo by’ubworozi bw’amafi ku isi yose n’ibindi bigo birenga 4.000 mu nganda zose mu bihugu birenga 55.

Inzira iri imbere

Nubwo isezerano ry’ikoranabuhanga rya nanobubble risobanutse neza, abashakashatsi bashimangira ko hakenewe isesengura rikomeye rigereranya uburyo busanzwe, ndetse no gusuzuma neza ingaruka ku buzima n’umutekano. Ubushakashatsi bw’ejo hazaza bugomba gusuzuma inyungu za nanobubble mu gihe zirimo ubwinshi bwinshi bw’amafi no mu gihe kirekire kugira ngo harebwe neza ingaruka zabyo ku bworozi bw’amafi bukoresha cyane.

Nubwo bimeze bityo ariko, ibimenyetso birimo kwiyongera: ikoranabuhanga rya nanobubble rigaragaza impinduka mu buryo bwo korora amafi menshi. Kuva ku gutanga ogisijeni ihanitse no gukoresha ingufu neza kugeza ku kurwanya indwara no kuvura amazi mabi, nanobubbles zirimo gutuma abakora babasha kubona umusaruro mwinshi kandi bigira ingaruka nke ku bidukikije. Mu gihe inganda zikomeje guhura n’ibikenewe byinshi n’amabwiriza akaze, ikoranabuhanga rya nanobubbles ritanga inzira isobanutse igana ahazaza harambye kandi heza.
