Ni ibihe bisabwa ku bwiza bw'amazi mu buhinzi bw'isambaza zo mu mazi meza?

I. Ibipimo by'ingenzi by'ubwiza bw'amazi n'ibisabwa mu buhinzi bw'isambaza zo mu mazi meza

(1)Ogisijeni Yashongeshejwe (DO)

Ogisijeni yashongeshejwe ni ingenzi kugira ngo shrimp zo mu mazi zikomeze kubaho. Muri rusange igomba kubungabungwa hejuru y'amazi.5 mg/L‌, hamwe n'umubare ntarengwa w'ibipimo utarenze ‌3 mg/LIyo ogisijeni yashongeshejwe idahagije, isambaza zishobora kugaragaza umwuka ukabije (zireremba hejuru y'amazi), kugabanuka k'ibyo kurya, kandi mu bihe bikomeye, kubura umwuka no gupfa bitewe no kubura umwuka. Amasaha ya nijoro na mu gitondo cya kare agaragaza ko urugero rwa ogisijeni yashongeshejwe mu mazi ari hasi cyane, bigasaba gukurikiranwa neza.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Ogisijeni Yashongeshejwe (DO):Ingano ya gaze ya ogisijeni (O₂) ishongeshejwe mu mazi, ni ingenzi mu guhumeka kw'ibinyabuzima byo mu mazi.
• Urugero rw'ikoreshwa: Mu bworozi bw'amafi, urugero rwa DO ruri munsi ya 4 mg/L rukunze gutera ibibazo mu bwoko nka tilapia.
• Ibimenyetso bikunze kubaho: Sisitemu zo guhumeka zikunze gukoreshwa mu masaha ya mugitondo iyo DO igeze aho igeze.

(2)Ubushyuhe n'ubutare (Agaciro ka pH)

Igipimo cyiza cya pH ku bimera byo mu mazi meza ni7.0–8.5‌, hamwe n'ihindagurika rya buri munsi rigenzurwa muri ‌Ibice ± 0.5‌. Agaciro ka pH kari hasi cyane gashobora gutera aside mu mafi ya shrimp, bikabangamira imikurire n'imikurire yayo; ku rundi ruhande, pH iri hejuru cyane yongera uburozi bwa azote ya ammonia, bigatera ikibazo gikomeye ku buzima bwa shrimp.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Agaciro ka pH:Igipimo cy'ubushyuhe cyangwa alkali mu gisubizo ku gipimo kuva kuri 0 kugeza kuri 14, aho 7 ari ntarengwa.
• Urugero: Kugabanuka gutunguranye kwa pH nyuma y'imvura nyinshi bishobora gutera ubwoba ibinyabuzima byo mu mazi mu byuzi byo hanze.
• Ibimenyetso bikunze kubaho: Ibintu bifasha mu gufunga amazi nka kalisiyumu karubone byongerwamo kugira ngo pH ihore ihamye mu buryo bwo korora amazi mu mazi.

(3)Azote ya Ammonia na Nitrite

Igipimo cya azote ya amoniya kigomba kugenzurwa munsi ya0.2 mg/L‌, hamwe n'urugero rwa ammonia rudafite ioni (molekyuli) ruri munsi ya ‌0.1 mg/LAmmonia nyinshi yangiza ingirangingo z'inyama z'ifi kandi ikabuza imikorere y'ubuhumekero. Igipimo cya nitrite kigomba kuguma munsi ya0.1 mg/L‌, kuko bigabanya ubushobozi bwo gutwara ogisijeni mu maraso y'isambaza, bigatera "uburozi bwa nitrite," bigatera kugabanuka k'imbaraga no kudakira indwara.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Azote ya Ammonia (NH₃/NH₄⁺):Imyanda y’uburozi iva mu nyamaswa zo mu mazi. Ammonia idafite iyoni (NH₃) ni uburozi bwinshi nubwo yaba iri hasi.
• ‌Nitrite (NO₂⁻):Ni ikintu kiri hagati mu mikorere ya azote; ni uburozi kuko ifatana na hemocyanin (umuyoboro wa ogisijeni mu bimera binini), ikagabanya uburyo ogisijeni itwarwamo.
• Urugero rw'ikoreshwa: Mu byuma biyungurura ibimera, bagiteri z'ingirakamaro zihindura ammonia → nitrite → nitrate (uburozi budakabije).
• Ibimenyetso bikunze kubaho: Nyuma yo kubika shrimp nshya, amoniya ishobora kugaragara bitewe no kurya cyane cyangwa kudashobora kuyungurura neza.
• ‌Uburemere bwose bw'ibinyabutabire:Ingano isabwa:80–150 mg/Lnka CaCO₃. Ifasha mu kugabanya ihindagurika rya pH no kubungabunga ubusugire bw'amazi.
• ‌Gukorera mu mucyo mu mazi:Urutonde rwiza:30–40 cm‌, bigaragaza ubwinshi bukwiye bwa phytoplankton, butanga ibiryo karemano bya shrimp.
• ‌Sulfide ya Hydrogen (H₂S):Bigomba kugenzurwa neza munsi0.01 mg/LUyu mwuka uhumanya cyane, ukorwa mu gihe nta mwuka urimo gutera, ushobora kwangiza cyane ingingo no gupfa kw'inkeri.

(4) Izindi Parametero

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Uburemere bwose bw'ibinyabutabire:Ubushobozi bw'amazi bwo kwangiza aside, ahanini bitewe na iyoni za bicarbonate, carbonate, na hydroxide.
• Urugero: Ibidendezi bifite alkali nke akenshi bisaba kongerwamo lime (kongeramo lime) kugira ngo byongere ubushobozi bwo gufunga.
• ‌Umucyo:Bipimwe hakoreshejwe Secchi disk; bigaragaza ubucucike bwa plankton n'ubuziranenge bw'amazi muri rusange.
• ‌Sulfide ya Hydrogen (H₂S):Imyuka idafite ibara kandi ishobora gushya ifite impumuro y'amagi yaboze; ni uburozi bukabije ku binyabuzima byo mu mazi ndetse no ku rugero ruto.
• Ibimenyetso bikunze kubaho: Kwirundanya kw'ibimera mu mazi biri hasi mu cyuzi bituma habaho kubora kw'ibimera bidafite umwuka mwiza ndetse n'umusaruro wa H₂S.

II. Ni gute wahitamo ibikoresho byo kugenzura ubuziranenge bw'amazi?

(1) Gusobanura neza ibikenewe mu igenzura

Abahinzi bagomba guhitamo ibikoresho byo gukurikirana bikwiye hashingiwe kuubuhinzi‌,‌imiterere y'amazinaibipimo by'ingenzi by'inyunguKu igenzura ry'ibanze (urugero, pH na DO), ibikoresho bikora imikorere imwe bishobora kuba bihagije. Ariko, kugira ngo hamenyekane neza ubuziranenge bw'amazi,sisitemu zo kugenzura ibintu byinshibirasabwa.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Igenzura ry'ibipimo byinshi:Igikoresho gishobora gupima ibipimo byinshi by'ubuziranenge bw'amazi icyarimwe (urugero: pH, DO, ubwikorezi bw'amazi, ubushyuhe, amoniya).
• Urugero: Amasambu manini y’isambaza akoresha sondes zifite ibipimo byinshi kugira ngo akurikirane imiterere y’amazi mu gihe nyacyo.
• Ibimenyetso bikunze kubaho: Utwobo duto dushobora gukoresha ibyuma bipima ingano y’amatungo mu buryo bwo kugenzura aho ibintu biherereye, mu gihe ibyuma bipima ingano y’amafi (RAS) mu nganda (Recirculating Aquaculture Systems) byishingikiriza ku bikoresho bipima ingano bya interineti.

(2) Shimangira ku kuri kw'igikoresho no ku buryo gihamye

Ibikoresho bitanga amakuru yizewe kugira ngo bifatwe ibyemezo bifatika. Byongeye kandi, ibikoresho bigomba kugaragaza ko bihamye kugira ngo bikore mu buryo buhoraho mu turere tugoranye tw’ubworozi bw’amafi, bigabanye ibyago byo kwangirika.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Uburinganire:‌ Kuba agaciro gapimwe kegereye agaciro nyakuri. Ubuhanga buhanitse butuma ibisubizo byizewe.
• ‌Ituze:Ubushobozi bw'igikoresho cyo kugumana imikorere ihamye mu gihe runaka nta guhindagurika.
• Urugero: Sensor ya DO ifite ubushobozi buke bwo gupima ibintu ishobora gusaba ko ivugururwa buri munsi, bigatuma ikiguzi cy'abakozi cyiyongera.
• Ibimenyetso bikunze kubaho: Ibikoresho by’ikoranabuhanga byagenewe kurwanya ihumana no kugumana uburyo bwo kugenzura mu gihe cy’ibyumweru byinshi.

(3) Tekereza ku byorohereza imikorere n'ibiciro byo kubungabunga

Ibikoresho byoroshye gukoresha kandi byoroshye kubungabunga bigabanya imbogamizi mu bya tekiniki ku bahinzi kandi bigagabanya ikiguzi cy'ibikorwa mu gihe kirekire. Ibikoresho bifitegupima mu buryo bwikoranaimirimo yo kwisukurakugabanya uburyo bwo gukora ibikorwa hakoreshejwe intoki no kunoza imikorere y'igenzura.

‌Ibisobanuro by'amagambo y'ingenzi:‌

• ‌Gupima byikora:Igikoresho gihindura imiterere yacyo mu buryo bwikora gikoresheje amahame ngenderwaho, bigabanura amakosa y'umukoresha.
• ‌Uburyo bwo kwisukura:Ikoresha udupira twa mechanical cyangwa vibration ya ultrasound kugira ngo hirindwe ko biofouling ku buso bwa sensor.
• Urugero: Imashini zipima pH zisukura ubwazo ni nziza cyane mu gihe kirekire mu byuzi by’ibimera bikungahaye ku ntungamubiri.
• Ibimenyetso bikunze kubaho: Sisitemu zikoresha ikoranabuhanga zigabanya ibyo abakozi bakeneye kandi zigatuma habaho igenzura ryihariye mu bigo bitagira abapilote.
