Impendulo kaPenaeus vannamei kwizinto ezitshintshileyo zendalo ibizwa ngokuba yi-"respond stress", kwaye utshintsho lweempawu ezahlukeneyo zomzimba nezekhemikhali emanzini zonke zizinto ezibangela uxinzelelo. Xa ii-shrimps zisabela kutshintsho lwezinto ezibangela indalo, amandla azo omzimba aya kuncipha kwaye amandla amaninzi omzimba aya kusetyenziswa; Ukuba uluhlu lotshintsho lwezinto ezibangela uxinzelelo alukho mkhulu kwaye ixesha alikho lide, ii-shrimps zinokukwazi ukumelana nalo kwaye aziyi kubangela umonakalo omkhulu; Ngokwahlukileyo koko, ukuba ixesha loxinzelelo lide kakhulu, utshintsho lukhulu, ngaphaya kokukwazi ukuziqhelanisa nee-shrimps, ii-shrimps ziya kugula okanye zife.

Ⅰ. Iimpawu zokusabela koxinzelelo lweeshrimp bezilandelayo

1. Iindevu ezibomvu, umlandeli womsila obomvu kunye nomzimba obomvu we-shrimp (eyaziwa ngokuba ngumzimba obomvu oxinezelekileyo);

2. Nciphisa izinto ezisetyenzisiweyo ngokukhawuleza, nokuba ungatyi izinto ezisetyenzisiweyo, qubha echibini

3. Kulula kakhulu ukutsibela edamini

4. Iigill ezimthubi, iigill ezimnyama kunye neendevu eziqhekekileyo kulula ukuzibona.

Ⅱ, Izizathu zokusabela koxinzelelo lweeprawn zezi zilandelayo:

1. Uguquko lwesigaba se-algae: njengokufa ngesiquphe kwe-algae, umbala wamanzi acacileyo okanye ukukhula kakhulu kwe-algae, kunye nombala wamanzi otyebileyo kakhulu;

2. Utshintsho lwemozulu, njengemiphumo emibi yemozulu efana nomoya obandayo, isivunguvungu, imvula eqhubekayo, isivunguvungu, imini enamafu, umahluko omkhulu wobushushu phakathi kokubanda nobushushu: isivunguvungu kunye nemvula eqhubekayo kuya kwenza amanzi emvula aqokeleleke phezu kwechibi leenkampi. Emva kwemvula, ubushushu bamanzi angaphezulu buphantsi kwaye ubushushu bamanzi asezantsi buphezulu, nto leyo ebangela ukujikeleza kwamanzi, kwaye inani elikhulu leenkampi zephotosynthesis ziyafa (utshintsho lwamanzi) ngenxa yokunqongophala kwenkampi yephotosynthesis. Kule meko, amanzi afumana i-hypoxia enzima; Ibhalansi encinci yendalo yomzimba wamanzi iyaphuka, kwaye iintsholongwane eziyingozi zisasazeka ngobuninzi (amanzi aba mhlophe kwaye abe mdaka), nto leyo ebangela ukuba izinto eziphilayo ezisezantsi kwechibi zibole kwaye zivelise i-hydrogen sulfide kunye ne-nitrite kwimeko ye-anaerobic kwaye zenze ukuqokelelana, nto leyo eya kubangela ityhefu kunye nokufa kweenkampi.

3. Utshintsho lweempawu ezibonakalayo nezekhemikhali emzimbeni wamanzi: utshintsho lobushushu bamanzi, ukucaca, ixabiso le-pH, i-ammonia nitrogen, i-nitrite, i-hydrogen sulfide kunye nezinye izalathisi nazo ziya kubangela ukuba ii-prawn zenze impendulo yoxinzelelo.

4. Ukutshintshwa kwexesha lelanga: ngenxa yotshintsho lwamaxesha elanga, imozulu engaqinisekanga, umahluko omkhulu wobushushu kunye necala lomoya elingaqinisekanga, utshintsho luhlala ixesha elide, nto leyo ebangela ukuba izinto ezibonakalayo nezekhemikhali zomzimba wamanzi eenkampi zitshintshe kakhulu, nto leyo ebangela uxinzelelo olunamandla lweenkampi ukuba lubangele ukuqhambuka kweentsholongwane kunye nokuphuma kwamanzi echibini elikhulu.

5. Ukusetyenziswa kwezibulali-zinambuzane ezivuselelayo, amayeza e-algal afana ne-copper sulfate, i-zinc sulfate, okanye izibulali-ntsholongwane ezine-chlorine kunokubangela impendulo enamandla yoxinzelelo kwi-prawn.

Ⅲ, Ukuthintela kunye nonyango lokuphendula koxinzelelo

1. Umgangatho wamanzi kunye nentlenge kufuneka ziphuculwe rhoqo ukuze kuthintelwe ukuphambuka kwamanzi;

Ukongezwa komthombo wekhabhoni kunokuphucula umgangatho wamanzi kwaye kuthintele ukuwa kwe-algae.

2. Kwimeko yomoya onamandla, imvula, iimvula ezinkulu, imini yemvula, umoya ovela emantla kunye nezinye imozulu embi, kufuneka kongezwe izondlo emanzini kwangethuba ukuthintela ukwenzeka kwempendulo yoxinzelelo;

3. Ubungakanani besongezo samanzi akufuneki bube bukhulu kakhulu, ngokubanzi malunga ne-250px ifanelekile. Iimveliso zokulwa noxinzelelo zingasetyenziselwa ukunciphisa impendulo yoxinzelelo;

4. Nika ingqalelo rhoqo kutshintsho lwemozulu, kwaye usebenzise iimveliso zokulwa noxinzelelo ukulungisa umgangatho wamanzi ngexesha.

5. Emva kokugqunywa kakhulu, ii-prawns kufuneka zongezwe i-calcium ngexesha elifanelekileyo ukuze ziqine ngokukhawuleza kwaye zinciphise uxinezeleko.
