Ukukhulisai-shrimp, kufuneka unyuse amanzi kuqala.Kuyo yonke inkqubo yokunyusa i-shrimp, ukulawulwa komgangatho wamanzi kubaluleke kakhulu.Ukongeza kunye nokutshintsha amanzi yenye yeendlela ezilula zokulawula umgangatho wamanzi.Ngaba ichibi le-shrimp kufuneka litshintshe amanzi?Abanye abantu bathi iiprawn ziethe-ethe kakhulu.Ukutshintsha i-spines ukuvuselela i-prawns kwiqokobhe rhoqo kuyenza buthathaka imizimba yazo kwaye iba sengozini yezifo.Abanye bathi akunakwenzeka ukuba ungawatshintshi amanzi.Emva kwexesha elide lokunyusa, umgangatho wamanzi u-eutrophic, ngoko kufuneka sitshintshe amanzi.Ngaba kufuneka nditshintshe amanzi kwinkqubo yokunyusa i-shrimp?Okanye phantsi kwaziphi iimeko amanzi anokutshintshwa kwaye phantsi kweziphi iimeko amanzi angenako ukutshintshwa?

 

Kuya kuhlangatyezwana nemiqathango emihlanu yokutshintsha kwamanzi okufanelekileyo

1. Iiprawn azikho kwixesha lencopho yeukugqobhoza, kwaye umzimba wabo ubuthathaka kweli nqanaba ukuphepha uxinzelelo olunzima;

2. Iiprawn zinomzimba osempilweni, amandla amahle, ukondla ngamandla kwaye akukho sifo;

3. Umthombo wamanzi uqinisekisiwe, iimeko zomgangatho wamanzi ase-offshore zilungile, izalathisi ezibonakalayo kunye neekhemikhali ziqhelekileyo, kwaye kukho umehluko omncinci kwi-salin kunye nokushisa kwamanzi kwi-shrimp pond;

4. Amanzi echibi lasekuqaleni anenzala ethile, kwaye i-algae inamandla;

5. Amanzi angenayo ahluzwa nge-mesh eshinyeneyo ukukhusela ngokungqongqo iintlanzi zasendle ezixubileyo kunye neentshaba ekungeneni kwi-shrimp pond.

Indlela yokukhupha kunye nokutshintsha amanzi ngokwesayensi kwinqanaba ngalinye

1) Isigaba sokuqala sokuzala.Ngokuqhelekileyo, amanzi kuphela ayongezwa ngaphandle kokukhutshwa kwamanzi, okunokuphucula ubushushu bamanzi ngexesha elifutshane kunye nokuhlakulela i-bait eziphilayo ezaneleyo kunye ne-algae enenzuzo.

Xa ufaka amanzi, unokucocwa ngemigangatho emibini yezikrini, kunye ne-60 mesh kuluhlu lwangaphakathi kunye ne-80 ye-mesh yoluhlu lwangaphandle, ukuze kuthintelwe izinto ezitshaba kunye namaqanda eentlanzi ekungeneni echibini le-shrimp.Yongeza amanzi malunga ne-3-5cm yonke imihla.Emva kweentsuku ezingama-20-30, ubunzulu bamanzi bunokufikelela ngokuthe ngcembe kwi-1.2-1.5m ukusuka kwi-50-60cm yokuqala.

2) Ukuzala kwexesha eliphakathi.Ngokuqhelekileyo, xa umthamo wamanzi udlula i-10cm, akufanelekanga ukutshintsha isikrini sokucoca ukususa ukungcola yonke imihla.

3) Emva kwexesha lokuzala.Ukuze kwandiswe ioksijini enyibilikisiweyo kumaleko asezantsi, amanzi echibini kufuneka alawulwe kwi-1.2m.Nangona kunjalo, ngoSeptemba, iqondo lokushisa lamanzi laqala ukuhla ngokuthe ngcembe, kwaye ubunzulu bamanzi bunokwandiswa ngokufanelekileyo ukuze kugcinwe ubushushu bamanzi, kodwa utshintsho lwamanzi lwemihla ngemihla aluyi kudlula i-10cm.

Ngokudibanisa kunye nokutshintsha amanzi, sinokuhlengahlengisa ubutyuwa kunye nomxholo wezondlo zamanzi kwi-shrimp pond, ukulawula ukuxinana kwe-algae ye-unicellular, ukulungelelanisa ukucaca, kunye nokunyusa umxholo we-oksijini onyibilikisiweyo wamanzi echibini le-shrimp.Ngexesha lobushushu obuphezulu, ukutshintsha amanzi kunokupholisa.Ngokudibanisa kunye nokutshintsha amanzi, i-pH yamanzi kwi-shrimp pond inokuzinza kwaye umxholo wezinto ezinobuthi ezifana ne-hydrogen sulfide kunye ne-ammonia nitrogen inokwehliswa, ukwenzela ukubonelela ngokusingqongileyo okulungileyo kokukhula kwe-shrimp.
