Impendulo kaPenaeus vannamei ezicini zemvelo ezishintshile ibizwa ngokuthi "impendulo yokucindezeleka", futhi ukuguquka kwezinkomba ezahlukene zomzimba nezamakhemikhali emanzini konke kuyizinto ezibangela ukucindezeleka. Lapho ama-shrimp esabela ezinguqukweni zezici zemvelo, amandla awo okuzivikela omzimba azoncishiswa futhi kuzosetshenziswa amandla amaningi omzimba; Uma uhla lokushintsha kwezici zokucindezeleka lungelukhulu futhi isikhathi singeside, ama-shrimp angakwazi ukubhekana nakho futhi ngeke abangele umonakalo omkhulu; Ngokuphambene nalokho, uma isikhathi sokucindezeleka side kakhulu, ushintsho lukhulu, ngale kokuzivumelanisa nezimo kwama-shrimp, ama-shrimp azogula noma afe.

Ⅰ. Izimpawu zokusabela kokucindezeleka kwe-shrimp bezingokulandelayo

1. Intshebe ebomvu, umlandeli womsila obomvu kanye nomzimba obomvu we-shrimp (owaziwa kakhulu ngokuthi umzimba obomvu wokucindezeleka);

2. Nciphisa izinto ngokushesha, ungadli izinto, bhukuda echibini

3. Kulula kakhulu ukugxumela echibini

4. Kulula ukubona ama-gill aphuzi, ama-gill amnyama kanye namadevu aphukile.

Ⅱ、 Izimbangela zokusabela kokucindezeleka kwama-prawn bezingokulandelayo:

1. Ukuguquka kwesigaba se-algae: njengokufa okungazelelwe kwe-algae, umbala wamanzi acwebezelayo noma ukukhula ngokweqile kwe-algae, kanye nombala wamanzi ojiyile kakhulu;

2. Ukushintsha kwesimo sezulu, njengemiphumela emibi yesimo sezulu njengomoya obandayo, isiphepho, imvula eqhubekayo, isiphepho, usuku olunamafu, umehluko omkhulu wokushisa phakathi kokubanda nokushisa: isiphepho semvula kanye nemvula eqhubekayo kuzokwenza amanzi emvula aqoqeke phezu kwechibi lezinkawu. Ngemva kwemvula, izinga lokushisa lamanzi angaphezulu liphansi kanti izinga lokushisa lamanzi angaphansi liphezulu, okubangela ukuhlangana kwamanzi, futhi inani elikhulu le-algae ye-photosynthesis liyafa (ukushintsha kwamanzi) ngenxa yokuntuleka kwe-algae ye-photosynthesis. Kulesi simo, amanzi abhekana ne-hypoxia enkulu; Ibhalansi encane yemvelo yomzimba wamanzi iyaphuka, futhi amagciwane ayingozi asakazeka ngobuningi obukhulu (amanzi aba mhlophe futhi abe mdaka), okubangela kalula ukuthi izinto eziphilayo ezingaphansi kwechibi zibole futhi zikhiqize i-hydrogen sulfide kanye ne-nitrite esimweni se-anaerobic futhi zakhe ukuqongelela, okuzobangela ubuthi nokufa kwenkawu.

3. Ukuguqulwa kwezinkomba zomzimba nezamakhemikhali emzimbeni wamanzi: ukuguqulwa kokushisa kwamanzi, ukucaca, inani le-pH, i-ammonia nitrogen, i-nitrite, i-hydrogen sulfide nezinye izinkomba nakho kuzobangela ukuthi ama-prawn akhiqize impendulo yokucindezeleka.

4. Ukushintshana kwesikhathi selanga: ngenxa yokushintsha kwamagama elanga, isimo sezulu esingalindelekile, umehluko omkhulu wokushisa kanye nesiqondiso somoya esingaqinisekile, ushintsho luhlala isikhathi eside, okubangela ukuthi izici zomzimba nezamakhemikhali zomzimba wamanzi e-shrimp zishintshe kakhulu, okubangela ukucindezeleka okukhulu kwama-prawn okubangela ukuqubuka kwegciwane kanye nokugeleza kwamanzi echibini elikhulu.

5. Ukusetshenziswa kwezibulala-zinambuzane ezivuselelayo, izidakamizwa ze-algal ezifana ne-copper sulfate, i-zinc sulfate, noma izibulala-magciwane eziqukethe i-chlorine kungaletha impendulo enamandla yokucindezeleka kuma-prawn.

Ⅲ, Ukuvimbela kanye nokwelashwa kokusabela kokucindezeleka

1. Ikhwalithi yamanzi kanye nenhlabathi kufanele kuthuthukiswe njalo ukuze kuvinjelwe ukuphambuka kwamanzi;

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

2. Uma kwenzeka umoya onamandla, isiphepho, isiphepho, usuku lwemvula, umoya osuka enyakatho kanye nezinye izimo zezulu ezimbi, ukudla okunomsoco kufanele kwengezwe emanzini ngesikhathi ukuze kuvinjelwe ukusabela kokucindezeleka;

3. Inani lesengezo samanzi akufanele libe likhulu kakhulu, ngokuvamile cishe ama-px angu-250 afanelekile. Imikhiqizo yokulwa nokucindezeleka ingasetshenziswa ukunciphisa ukusabela kokucindezeleka;

4. Nakisisa ukushintsha kwesimo sezulu njalo, bese usebenzisa imikhiqizo yokulwa nokucindezeleka ukuze ulungise ikhwalithi yamanzi ngesikhathi.

5. Ngemva kokuqotshwa kakhulu, ama-prawn kufanele afakwe i-calcium ngesikhathi ukuze aqine ngokushesha futhi anciphise ukusabela kokucindezeleka.
