Udindo wa zizindikiro zingapo ochiritsira thupi ndi mankhwala mu aquaculture

Mwambiwu umati kuweta nsomba kumadzutsa madzi poyamba, zomwe zimasonyeza kufunikira kwa chilengedwe chamadzi pazamoyo zam'madzi.Pakuswana, ubwino wa madzi a m'madzi amayesedwa makamaka pozindikira zizindikiro zingapo monga pH mtengo, ammonia nitrogen, nitrite nitrogen, sulfide ndi mpweya wosungunuka.Choncho, ndikofunika kwambiri kumvetsetsa udindo wa zizindikiro zingapo za thupi ndi mankhwala m'madzi .

1.pH

Acidity ndi alkalinity ndi chizindikiro chokwanira chomwe chimasonyeza ubwino wa madzi, komanso ndi chinthu chofunika kwambiri chomwe chimakhudza mwachindunji thanzi la nsomba.Zochita zatsimikizira kuti pH ya malo abwino kwambiri amadzi kuti nsomba zikule ndi pakati pa 7 ndi 8.5.Kukwera kwambiri kapena kutsika kwambiri kungakhudze kukula kwa nsomba komanso kufa kwa nsomba.Nsomba m'madzi amchere okhala ndi pH yoposa 9.0 zidzadwala alkalosis, ndipo zidzachititsa kuti nsombazo zitulutse ntchofu zambiri, zomwe zimakhudza kupuma.PH yapamwamba kuposa 10.5 idzachititsa kufa kwa nsomba.M'madzi acidic okhala ndi pH yotsika kuposa 5.0, mphamvu ya nsomba yonyamula okosijeni m'magazi imachepa, zomwe zimayambitsa hypoxia, dyspnea, kuchepa kwa chakudya, kuchepa kwa digestibility ya chakudya, komanso kukula pang'onopang'ono.Madzi a asidi amathandizanso ku matenda ambiri a nsomba omwe amayamba chifukwa cha protozoa, monga sporozoites ndi ciliates.

2.Dmpweya wosungunuka

Kusungunuka kwa okosijeni wosungunuka ndi chizindikiro chachikulu cha ubwino wa madzi a m'madzi, ndipo mpweya wosungunuka m'madzi a m'madzi ayenera kusungidwa pa 5-8 mg / L.Osakwanira kusungunuka mpweya kungayambitse mitu yoyandama, ndipo zikavuta, zidzakhudza kukula kwa nsomba ndi chifukwa imfa ya poto-mayiwe.The ndende ya kusungunuka mpweya mu madzi thupi mwachindunji zimakhudza zili poizoni zinthu m'madzi thupi.Kusunga mpweya wokwanira wosungunuka m'madzi kungachepetse zinthu zapoizoni monga nitrite nayitrogeni ndi sulfide.Mpweya wokwanira wosungunuka m'madzi ukhoza kupititsa patsogolo chitetezo cha mthupi cha zinthu zobereketsa ndikuwonjezera kulolerana kwawo ndi malo ovuta.

1.Nayitrogeni wa nayitrogeni

Zomwe zili mu nitrite nitrogen m'madzi zimaposa 0.1mg/L, zomwe zingawononge nsomba mwachindunji.Kulepheretsa kwa nitrification m'madzi ndikomwe kumayambitsa kupanga nitrite nayitrogeni.Mchitidwe wa nitrification wa mabakiteriya opangira madzi amakhudzidwa ndi kutentha, pH ndi mpweya wosungunuka m'madzi.Choncho, nitrite nayitrogeni zili m'madzi zimagwirizana kwambiri ndi kutentha kwa madzi, pH ndi mpweya wosungunuka.

2. Sulfidi

Kawopsedwe wa sulfide makamaka amatanthauza kawopsedwe wa hydrogen sulfide.Hydrogen sulfide ndi chinthu chapoizoni kwambiri, ndende yotsika imakhudza kukula kwa zinthu zam'madzi, ndipo kukwera kwakukulu kungayambitse poizoni ndi kufa kwa zinthu zam'madzi.Kuwonongeka kwa hydrogen sulfide ndi kofanana ndi kwa nitrite, makamaka kumakhudza kunyamula mpweya wa magazi a nsomba, zomwe zimapangitsa kuti nsomba ikhale ndi hypoxia.Kuchuluka kwa hydrogen sulfide m'madzi am'madzi kuyenera kuyendetsedwa pansi pa 0.1mg/L.

Chifukwa chake, kumvetsetsa bwino zinthu zoyezetsazi, kuyesa pafupipafupi, komanso kutsatira njira zofananira munthawi yake kungathandize kwambiri kupulumuka kwa nsomba ndi shrimp ndikuchepetsa mtengo woswana.
