Organic acid na-ezo aka na ụfọdụ ogige ndị nwere acidity. Organic a na-ahụkarị bụ acid carboxylic, nke acid ya sitere na otu carboxyl. Methyl calcium, acetic acid, wdg bụ organic acids, nke nwere ike imeghachi omume na mmanya na-etolite esters.

★ Ọrụ nke organic asịd na aquatic ngwaahịa

1. Mee ka nsị nke ọla dị arọ belata, gbanwee amonia ahụ dị na mmiri aquaculture, ma belata nsị nke amonia na-egbu egbu.

2. Organic acid nwere ọrụ nke iwepụ mmetọ mmanụ. Enwere ihe nkiri mmanụ na ọdọ mmiri ahụ, ya mere enwere ike iji acid acid mee ihe.

3. Organic acid nwere ike idozi pH nke mmiri ma dozie ọrụ mmiri.

4. O nwere ike belata viscosity nke mmiri, decompose organic okwu site flocculation na mgbagwoju anya, ma melite elu erughị ala nke mmiri.

5. Organic acid nwere ọnụ ọgụgụ dị ukwuu nke ndị na-eme mmiri, nke nwere ike ịme ọla dị arọ, mebie ngwa ngwa, belata esemokwu dị na mmiri, igbari ikuku oxygen na ikuku n'ime mmiri ngwa ngwa, meziwanye ike ikuku oxygen na mmiri, ma chịkwaa isi na-ese n'elu mmiri.

★ Emehie ihe n'iji organic acid

1. Mgbe nitrite dị na ọdọ mmiri karịa ụkpụrụ ahụ, iji acid acids eme ihe ga-ebelata pH ma mee ka nsí nke nitrite dịkwuo ukwuu.

2. Enweghị ike iji ya na sodium thiosulfate. Sodium thiosulfate na-emeghachi omume na acid iji mepụta sọlfọ dioxide na elemental sọlfọ ahụ, nke ga-emebi nsị ozuzu.

3. Enweghị ike iji ya rụọ sodium humate. Sodium humate adịghị ike alkaline, a ga-ebelata mmetụta ya nke ukwuu ma ọ bụrụ na ejiri ya abụọ.

★ Ihe na emetuta ngwa ndi ozo

1. Ngwurugwu: mgbe etinyere otu organic acid na nri nke umu anumanu, ma otutu otutu di iche, mmetuta di iche. Odi iche na onodu onu ogugu di egwu, onu ogugu, onu ogugu oriri na oru protein; N'ime otu mgbakwunye nke acid acid mgbakwunye, na mmụba nke mgbakwunye acid, a ga-akwalite uto nke ụdị ndị a zụlitere, mana mgbe ọ gafere karịa ụfọdụ, mgbakwunye dị elu ma ọ bụ dị obere nke acid acid ga-egbochi uto nke ụdị ndị a zụlitere na belata itinye n'ọrụ nke nri, na ihe kacha adabara organic acid mgbakwunye maka dị iche iche aquatic anụmanụ ga-adị iche.

2. Na-agbakwunye oge: mmetụta nke ịgbakwunye organic acid na ọkwa uto dị iche iche nke ụmụ anụmanụ na-adị mmiri dị iche. Nsonaazụ gosiri na uto na-akwalite mmetụta bụ ihe kachasị mma na ọkwa nwata, na ogo mmụba dị elu bụ nke kachasị elu, ruo 24.8%. N'ebe ndị okenye nọ, mmetụta ahụ pụtara ìhè n'akụkụ ndị ọzọ, dịka mgbochi nrụgide mgbochi.

3. Ihe ndị ọzọ dị na nri: acid acids nwere mmetụta mmekọrịta na ngwa ndị ọzọ na nri. Mkpụrụ protein na abụba dị na nri ahụ nwere ikike nchekwa dị elu, nke nwere ike melite acidity nke ndepụta ahụ, belata ike nchekwa nke ndepụta ahụ, mee ka absorption na metabolism dị mfe, si otú a na-emetụta nri nri na mgbaze.

4. Ọnọdụ ndị dị na mpụga: mmiri dị mma dị mma, ụdị dị iche iche na ọnụ ọgụgụ ndị ọzọ nke ụdị phytoplankton ndị ọzọ na gburugburu mmiri, ezigbo nri dị mma, etolite etolite na ọrịa na-enweghị ọrịa, yana oke nsị nke ezi uche dịkwa oke mkpa maka mmetụta kacha mma nke acid acid .

5. Na-arụsi ọrụ ike onyinye organic asịd: ịgbakwunye na-arụ ọrụ nwere ike belata ego agbakwunyere organic asịd na nweta ihe mgbaru ọsọ ka mma.
