Impendulo kaPenaeus vannamei kwizinto ezitshintshileyo zokusingqongileyo ibizwa ngokuba "yimpendulo yoxinzelelo", kwaye ukuguqulwa kwezalathisi ezahlukeneyo zomzimba kunye neekhemikhali emanzini zizinto zonke zoxinzelelo.Xa i-shrimps isabela kwiinguqu zezinto ezisingqongileyo, amandla abo omzimba aya kuncitshiswa kwaye amandla amaninzi omzimba aya kusetyenziswa;Ukuba uluhlu lwezinto ezitshintshileyo zoxinzelelo alukho lukhulu kwaye ixesha alikho ixesha elide, i-shrimp inokumelana nayo kwaye ayiyi kubangela ingozi enkulu;Ngokuchasene noko, ukuba ixesha loxinzelelo lide kakhulu, utshintsho lukhulu, ngaphaya kokulungelelaniswa kwe-shrimp, i-shrimp iya kugula okanye ife.

Ⅰ.Iimpawu zokusabela koxinzelelo lwe-shrimp zazi ngolu hlobo lulandelayo

1. Iindevu ezibomvu, umsila obomvu obomvu kunye nomzimba obomvu we-shrimp (eyaziwa ngokuba ngumzimba obomvu woxinzelelo);

2. Nciphisa izinto ngokubukhali, nokuba ungatyi izinto, qubha ecaleni kwedama

3. Kulula kakhulu ukutsibela echibini

4. Iigill eziphuzi, iigill ezimnyama kunye namabhovu aphukileyo kulula ukuvela.

Ⅱ, Iimbangela zokusabela koxinzelelo lweprawn bezimi ngolu hlobo lulandelayo:

1. Ukuguqulwa kwesigaba se-algae: njengokufa ngequbuliso kolwelwe, umbala ocacileyo wamanzi okanye ukukhula okugqithisileyo kolwelwe, kunye nombala wamanzi angqindilili kakhulu;

2. Ukutshintsha kwemozulu, njengeempembelelo ezinzima zemozulu ezifana nomoya obandayo, isitshingitshane, imvula eqhubekayo, imvula, imini enamafu, umehluko omkhulu wokushisa phakathi kwebanda kunye nobushushu: imvula kunye nemvula eqhubekayo iya kwenza amanzi emvula aqokelele phezu komphezulu we-shrimp pond.Emva kwemvula, ubushushu bamanzi angaphezulu buphantsi kwaye ubushushu bamanzi asezantsi buphezulu, nto leyo ebangela ukuguquguquka kwamanzi, kwaye inani elikhulu le-photosynthesis algae liyafa (utshintsho lwamanzi) ngenxa yokungabikho kwe-photosynthesis algae.Kule meko, amanzi afumana i-hypoxia enzima;I-micro ecological balance yomzimba wamanzi yaphukile, kwaye ii-microorganisms ezinobungozi zisasazeka ngobuninzi (amanzi aba mhlophe kunye ne-turbid), nto leyo eyenza lula ukuba i-organic matter esezantsi kwedama ibole kwaye ivelise i-hydrogen sulfide kunye ne-nitrite kwimeko ye-anaerobic kwaye ukuqokelela, okuya kubangela ubuthi kunye nokufa kwe-shrimp.

3. Ukuguqulwa kwezalathisi ezibonakalayo kunye neekhemikhali kumzimba wamanzi: ukuguqulwa kobushushu bamanzi, ukungafihli, ixabiso le-pH, i-ammonia nitrogen, i-nitrite, i-hydrogen sulfide kunye nezinye izikhombisi ziya kubangela ukuba i-prawn ivelise impendulo yoxinzelelo.

4. Ukutshintshwa kwexesha lelanga: ngenxa yokutshintsha kwamagama elanga, imozulu engalindelekanga, umahluko omkhulu wobushushu kunye nesikhokelo somoya esingaqinisekanga, utshintsho luhlala ixesha elide, nto leyo ebangela ukuba izinto ezibonakalayo kunye neekhemikhali zomzimba wamanzi we-shrimp zitshintshe kakhulu, nto leyo ebangela ukuba ukutshintshwa kwemeko yelanga. uxinzelelo olomeleleyo lweprawn ukubangela ukuqhambuka kwentsholongwane kunye nomthamo omkhulu wokuhambisa amanzi echibini.

5. Ukusetyenziswa kwezinambuzane ezikhuthazayo, iziyobisi ze-algal ezifana ne-copper sulfate, i-zinc sulfate, okanye i-chlorine equkethe i-disinfectants inokuzisa uxinzelelo olunamandla kwi-prawn.

Ⅲ, Uthintelo kunye nonyango lokusabela koxinzelelo

1. Umgangatho wamanzi kunye nentlenga kufuneka iphuculwe rhoqo ukunqanda ukuphambukiswa kwamanzi;

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

2. Kwimeko yomoya onamandla, imvula, isiphango, imini yemvula, umoya osenyakatho kunye nezinye imozulu embi, isondlo kufuneka songezwe kumzimba wamanzi ngexesha lokuthintela ukuvela koxinzelelo;

3. Isixa sesongezo samanzi akufanele sibe sikhulu kakhulu, ngokubanzi malunga ne-250px ifanelekile.Iimveliso ezichasene noxinzelelo zingasetyenziselwa ukunciphisa ukusabela koxinzelelo;

4. Nika ingqwalasela ngokucokisekileyo kutshintsho lwemozulu rhoqo, kwaye usebenzise iimveliso ezichasene noxinzelelo ukulungelelanisa umgangatho wamanzi ngexesha.

5. Emva kobuninzi be-shelling, iiprawn kufuneka zongezwe nge-calcium ngexesha ukuze zenze i-shell shelled ngokukhawuleza kwaye zinciphise ukusabela koxinzelelo.
