Impendulo kaPenaeus vannamei ezicini ezishintshile zemvelo ibizwa ngokuthi "impendulo yokucindezeleka", futhi ukuguqulwa kwezinkomba ezihlukahlukene zomzimba namakhemikhali emanzini zonke ziyizici zokucindezeleka.Lapho ama-shrimps esabela ekushintsheni kwezici zemvelo, amandla abo omzimba azoncishiswa futhi amandla amaningi omzimba azosetshenziswa;Uma uhla lwezinguquko lwezici zokucindezeleka lungelikhulu futhi isikhathi singeside, ama-shrimp angakwazi ukubhekana nawo futhi angeke abangele umonakalo omkhulu;Ngokuphambene nalokho, uma isikhathi sokucindezeleka siside kakhulu, ushintsho lukhulu, ngaphezu kokuvumelana nezimfanzi, izimfanzi zizogula noma zife.

Ⅰ.Izimpawu zokusabela kokucindezeleka kwezimfanzi zazimi kanje

1. Intshebe ebomvu, ifeni yomsila obomvu nomzimba obomvu wezimfanzi (okwaziwa kakhulu ngokuthi umzimba obomvu wokucindezeleka);

2. Nciphisa ngokucijile, noma ungadli impahla, bhukuda eduze kwechibi

3. Kulula kakhulu ukugxumela echibini

4. Amagill aphuzi, amagill amnyama namadevu aphukile kulula ukuvela.

Ⅱ, Izimbangela zokusabela kokucindezeleka kwama-prawn zazimi kanje:

1. Ukuguqulwa kwesigaba solwelwe: njengokufa kungazelelwe ulwelwe, umbala wamanzi acwebile noma ukukhula ngokweqile kolwelwe, nombala wamanzi awugqinsi kakhulu;

2. Ukushintsha kwesimo sezulu, njengemiphumela emibi kakhulu yesimo sezulu njengomoya obandayo, isishingishane, imvula eqhubekayo, isiphepho, usuku oluguqubele, umehluko omkhulu wamazinga okushisa phakathi kwamakhaza nokushisayo: isiphepho semvula kanye nemvula eqhubekayo kuzokwenza amanzi emvula aqoqene phezu kwechibi lezimfanzi.Ngemva kwemvula, izinga lokushisa kwamanzi angaphezulu liphansi futhi izinga lokushisa lamanzi aphansi liphakeme, okubangela ukuguquguquka kwamanzi, futhi inani elikhulu le-photosynthesis algae liyafa (ukushintsha kwamanzi) ngenxa yokuntuleka kwe-photosynthesis algae.Kulesi simo, amanzi abhekana ne-hypoxia enzima;Ibhalansi yemvelo encane yomzimba wamanzi iphukile, futhi ama-microorganisms ayingozi asakazeka ngobuningi (amanzi aba mhlophe futhi abe yi-turbid), okwenza kalula izinto eziphilayo ezingaphansi kwechibi ukuthi zibole futhi zikhiqize i-hydrogen sulfide ne-nitrite esimweni se-anaerobic futhi ukuqongelela, okuzodala ubuthi nokufa kwezimfanzi.

3. Ukuguqulwa kwezinkomba ezibonakalayo namakhemikhali emzimbeni wamanzi: ukuguqulwa kwezinga lokushisa lamanzi, ukubonakala obala, inani le-pH, i-ammonia nitrogen, i-nitrite, i-hydrogen sulfide nezinye izinkomba nakho kuzobangela ukuba umdambi ukhiqize ukuphendula ngokucindezeleka.

4. Ukushintshwa kwethemu lelanga: ngenxa yokushintsha kwamagama elanga, isimo sezulu esingalindelekile, umehluko omkhulu wokushisa kanye nesiqondiso somoya esingaqinisekile, uguquko luhlala isikhathi eside, okubangela ukuthi izici ezingokomzimba namakhemikhali omzimba wamanzi wezimfanzi zishintshe kakhulu, okubangela ukucindezeleka okunamandla kwe-prawn kubangela ukuqubuka kwegciwane kanye nokugeleza kwamanzi echibini okukhulu.

5. Ukusetshenziswa kwezibulala-zinambuzane ezivuselelayo, izidakamizwa ze-algal ezifana ne-copper sulfate, i-zinc sulfate, noma i-chlorine equkethe izibulala-magciwane kungaletha ukusabela okunamandla kwengcindezi kuma-prawn.

Ⅲ, Ukuvimbela nokwelashwa kokusabela kokucindezeleka

1. Izinga lamanzi kanye nenhlabathi kufanele kuthuthukiswe njalo ukuze kuvinjwe ukuphambukiswa kwamanzi;

Ukwengezwa komthombo wekhabhoni kungathuthukisa ikhwalithi yamanzi futhi kuvimbele ukuwa kwe-algae.

2. Uma kunomoya onamandla, isivunguvungu, ukuduma kwezulu, usuku lwemvula, umoya ovela enyakatho kanye nezinye izimo zezulu ezimbi, umsoco kufanele wengezwe emzimbeni wamanzi ngesikhathi ukuvimbela ukuvela kokusabela kokucindezeleka;

3. Inani lesithasiselo samanzi akufanele libe likhulu kakhulu, ngokuvamile cishe ngo-250px kufanelekile.Imikhiqizo elwa nokucindezeleka ingasetshenziswa ukunciphisa ukusabela kokucindezeleka;

4. Nakisisa ukushintsha kwesimo sezulu njalo, futhi usebenzise imikhiqizo yokulwa nokucindezeleka ukuze ulungise izinga lamanzi ngesikhathi.

5. Ngemuva kwenani elikhulu le-shelling, ama-prawns kufanele afakwe nge-calcium ngesikhathi ukuze awenze abe amagobolondo aqinile ngokushesha futhi anciphise ukusabela kokucindezeleka.
