Shanduko muDziva Pazasi Mamiriro Pakati Pese Aquaculture Stages

Zvinonyatsozivikanwa kuti kutonga kwemhando yemvura kwakakosha mune zvemumvura, uye kunaka kwemvura kunodyidzana nemamiriro epasi pedhamu. Yakanaka dziva rezasi mhando inofambisa kusimudzira kweaquaculture. Ichi chinyorwa chinotarisa nezve shanduko yepasi pemadziva mamiriro pamatanho akasiyana eiyo aquaculture maitiro uye anoenderana matanho.

Munguva yeaquaculture process, pazasi padziva kazhinji inochinja ina: organicization, kuderedza, toxicification, uye acidification.

Nhanho yekutanga yeAquaculture-Kuronga

Mumatanho ekutanga ezvekurima kwemvura, sezvo kudya kunowedzera, kuunganidzwa kwemarara, chikafu chinosara, uye tsvina pazasi pedhamu zvinotungamira kukuvaka zvishoma nezvishoma kweiyo organic matter, maitiro anozivikanwa se organicization. Panguva ino, mazinga eokisijeni anenge akakwana. Chinangwa chikuru ndechekuora sludge netsvina pazasi pedhamu, ichivashandura kuita inorganic munyu uye zvinovaka muviri kusimudzira algae kukura uye kuwedzera yakanyungudika okisijeni mumvura. Microbial strains inogona kushandiswa kubatsira kuodza madhaka netsvina.

Mid Stage yeAquaculture-Kuderedza

Sezvo aquaculture inofambira mberi, kunyanya panguva yekudya kwepamusoro kwemhuka dzemumvura, huwandu hwekudya hunoramba huchiwedzera, zvichikonzera kuunganidza zvishoma nezvishoma zvinhu zvehupenyu mudziva izvo zvinopfuura simba rekuzvichenesa kwemuviri wemvura. Kuwanda kwemarara ehupenyu kunokonzera kuora kweanaerobic pasi, kunotungamirira kumvura yakasviba uye inonhuwa, uye kupinda muchikamu chekudzikisa apo mvura zvishoma nezvishoma inova oksijeni-inopera. Semuenzaniso, sulfate inoshandura kuita hydrogen sulfide, uye ammonia nitrogen inoshanduka kuita nitrite. Mhedzisiro yekudzikisira kwakakosha kuderera kweokisijeni pazasi pedziva, zvichitungamira kudziva hypoxia. Panguva ino, zvinokurudzirwa kushandisa oxidizing ejenti pazasi shanduko, senge potassium monopersultate compound uye sodium percarbonate. Aya oxidizing agents anogona oxidize pasi pedziva sludge, kuderedza kushandiswa kweokisijeni, uye kugadzirisa oxidation mukana wekubvisa zvitema nekunhuwa.

Late Mid Stage yeAquaculture-Toxicification

Munguva yekupedzisira yepakati, dziva rinoburitsa huwandu hwakakura hwezvinhu zvine chepfu, zvinosanganisira hydrogen sulfide, ammonia nitrogen, nitrite, uye methane. Kunyanya hydrogen sulfide uye nitrite inogona kukonzera kutadza kufema kana kutadza kufema muhove, shrimp, uye magakanje. Nokudaro, kana mazinga e nitrite uye ammonia nitrogen akakwidziridzwa, zvinokurudzirwa kushandisa detoxifying agents kuderedza zvinhu izvi zvine chepfu.

Late Stage of Aquaculture-Acidification

Nekunopera nhanho yekurimwa kwemvura, pasi pedziva panobva paita acidic nekuda kwekuvirisa kweanaerobic kwehuwandu hwezvinhu zvipenyu, zvichikonzera kudzikira pH uye kuwedzera muchetura wehydrogen sulfide. Panguva ino, lime inogona kuiswa kunzvimbo dzine matope akawanda kuti isaite acidity yepasi pedhamu, kusimudza pH, uye kuderedza huturu hwehydrogen sulfide.
