Liphetoho ho Maemo a Letamo a Tlase ho Methati eohle ea Aquaculture

Hoa tsebahala hore taolo ea boleng ba metsi e bohlokoa haholo temong ea metsing, 'me boleng ba metsi bo amana haufi-ufi le boemo ba tlase ea letamo. Boleng bo botle ba matangoana bo thusa ntlafatso ea temo ea metsing. Sengoliloeng sena se tla shebana le liphetoho tsa maemo a tlase a letamo ka mekhahlelo e fapaneng ea ts'ebetso ea ts'ebetso ea aquaculture le mehato e lumellanang.

Nakong ea ts'ebetso ea aquaculture, tlase ea letamo hangata e ba le liphetoho tse 'ne: organicization, phokotso, chefo, le acidification.

Mokhahlelo oa Pele oa Thuto ea Tlhapi ea Metsing—Mokhatlo o hlophisitsoeng

Mekhahlelong ea pele ea temo ea metsing, ha phepelo e ntse e eketseha, ho bokellana ha lithōle, lijo tse setseng, le mantle ka tlas'a letamo ho lebisa ho haheng ha lintho tse phelang butle-butle, e leng mokhoa o tsejoang e le organicization. Mothating ona, maemo a oksijene a batla a lekane. Sepheo se seholo ke ho bolisa litšila le mantle a ka tlas'a letamo, ho li fetola matsoai a sa tloaelehang le limatlafatsi ho khothalletsa ho hōla ha algae le ho eketsa oksijene e qhibilihisitsoeng metsing. Mefuta ea likokoana-hloko e ka sebelisoa ho thusa ho bolisa litšila le mantle.

Mokhahlelo o Mahareng oa Tlhapi ea Metsing—Phokotso

Ha temo ea metsing e ntse e tsoela pele, haholo-holo nakong ea tlhōrō ea phepelo ea liphoofolo tsa metsing, lijo li tsoela pele ho eketseha, e leng se bakang ho bokellana butle-butle ha lintho tse phelang ka letamong tse fetang matla a ho itlhoekisa a 'mele oa metsi. Bongata bo bongata ba litšila tsa tlhaho bo senyeha ka tlas'a anaerobic, bo lebisang ho metsi a matšo le a nkhang hampe, 'me a kena mokhahlelong oa phokotso moo butle-butle metsi a fetohang oksijene. Ka mohlala, sulfate e fetoha hydrogen sulfide, 'me ammonia nitrogen e fetoha nitrite. Sephetho sa phokotso ke ho fokotseha ho hoholo ha oksijene botebong ba letamo, ho lebisang ho hypoxia ea letamo. Mothating ona, ho kgothaletswa ho sebelisa li-oxidizing agents bakeng sa phetoho e ka tlase, joalo ka motsoako oa potassium monopersulfate le sodium percarbonate. Lisebelisoa tsena tsa oxidizing li ka etsa oxidize seretse se ka tlase ho letamo, tsa fokotsa ts'ebeliso ea oksijene, le ho ntlafatsa bokhoni ba oxidation ho tlosa litaba tse ntšo le monko.

Morao oa Bohareng ba Mokhahlelo oa Tlhaho ea Metsing—Ho Felisa Chefo

Qetellong ea letamo, letamo le hlahisa lintho tse chefo tse ngata, ho kenyelletsa hydrogen sulfide, ammonia nitrogen, nitrite le methane. Haholo-holo hydrogen sulfide le nitrite li ka baka mathata a ho hema kapa esita le ho bipetsana litlhapi, shrimp le makhala. Ka hona, ha maemo a nitrite le ammonia nitrogen a phahame, ho eletsoa ho sebelisa li-detoxifying agents ho fokotsa lintho tsena tse chefo.

Mokhahlelo oa Morao-rao oa Aquaculture-Acidification

Nakong ea morao-rao ea temo ea metsing, letamo le fetoha acidic ka lebaka la ho belisoa ha anaerobic ea lintho tse ngata tse phelang, e leng se etsang hore pH e fokotsehe le ho eketseha ha chefo ea hydrogen sulfide. Mothating ona, kalaka e ka sebelisoa libakeng tse nang le seretse se bokeletsoeng ka ho fetesisa ho fokotsa acidity e tlase ea letamo, ho phahamisa pH, le ho fokotsa chefo ea hydrogen sulfide.
