Ukukhulisai-shrimp, kufuneka unyuse amanzi kuqala. Kuyo yonke inkqubo yokukhulisa ii-shrimp, ukulawulwa komgangatho wamanzi kubaluleke kakhulu. Ukongeza nokutshintsha amanzi yenye yezona ndlela zilula zokulawula umgangatho wamanzi. Ngaba ichibi lee-shrimp kufuneka litshintshe amanzi? Abanye abantu bathi ii-prawns zibuthathaka kakhulu. Ukutshintsha imiqolo ukuze zivuselele ii-prawns zibe ngamaqokobhe kuhlala kubuthathaka umzimba wazo kwaye zisengozini yezifo. Abanye bathi akunakwenzeka ukuba ungatshintshi amanzi. Emva kwexesha elide lokukhulisa, umgangatho wamanzi uba yinto engaqhelekanga, ngoko ke kufuneka sitshintshe amanzi. Ngaba kufuneka nditshintshe amanzi kwinkqubo yokukhulisa ii-shrimp? Okanye phantsi kwaziphi iimeko amanzi anokutshintshwa kwaye phantsi kwaziphi iimeko amanzi angenakutshintshwa?

 

Imiqathango emihlanu iya kuhlangatyezwana nayo yokutshintsha amanzi ngokufanelekileyo

1. Iiprawn azikho kwixesha eliphezuluukuqhumisa, kwaye umzimba wabo ubuthathaka kweli nqanaba ukuze baphephe uxinzelelo olunzima;

2. Iiprawns zinempilo entle, zinamandla, zitya ngamandla kwaye azinazifo;

3. Umthombo wamanzi uqinisekisiwe, iimeko zomgangatho wamanzi olwandle zilungile, ii-index zomzimba nezekhemikhali ziqhelekile, kwaye akukho mahluko mkhulu kwityuwa kunye nobushushu bamanzi echibini lee-shrimp;

4. Umzimba wamanzi edama lokuqala unomxhelo othile, kwaye ulwelwe lunamandla kakhulu;

5. Amanzi angena ngaphakathi ahluzwa nge-mesh exineneyo ukuthintela ngokungqongqo iintlobo ngeentlobo zeentlanzi zasendle kunye neentshaba ukuba zingangeni echibini lee-shrimp.

Indlela yokukhupha amanzi nokutshintsha amanzi ngokwesayensi kwinqanaba ngalinye

1) Inqanaba lokuzala kwangethuba. Ngokubanzi, kufakwa amanzi kuphela ngaphandle kokukhupha amanzi, nto leyo enokuphucula ubushushu bamanzi ngexesha elifutshane kwaye ikhulise izinto eziphilayo ezaneleyo zeentlanzi kunye ne-algae eluncedo.

Xa kugalelwa amanzi, angahluzwa ngee-screens ezimbini, kunye ne-mesh engama-60 yomaleko wangaphakathi kunye ne-mesh engama-80 yomaleko wangaphandle, ukuze kuthintelwe ukuba izinto eziphila kwiintshaba kunye namaqanda eentlanzi zingangeni echibini le-shrimp. Yongeza amanzi kangange-3-5cm yonke imihla. Emva kweentsuku ezingama-20-30, ubunzulu bamanzi bungafikelela kancinci kwi-1.2-1.5m ukusuka kwi-50-60cm yokuqala.

2) Ukuzala kwexesha eliphakathi. Ngokubanzi, xa umthamo wamanzi udlula i-10cm, akufanelekanga ukutshintsha isikrini sesihluzo ukuze kususwe ukungcola yonke imihla.

3) Inqanaba lokugqibela lokuzala. Ukuze konyuswe ioksijini enyibilikisiweyo kumaleko osezantsi, amanzi edama kufuneka alawulwe kwi-1.2m. Nangona kunjalo, ngoSeptemba, ubushushu bamanzi baqala ukwehla kancinci kancinci, kwaye ubunzulu bamanzi bunokwandiswa ngokufanelekileyo ukugcina ubushushu bamanzi buhlala bunjalo, kodwa utshintsho lwamanzi lwemihla ngemihla aluyi kudlula kwi-10cm.

Ngokongeza nangokutshintsha amanzi, singalungisa ubunzulu betyuwa kunye nomxholo wezondlo zamanzi echibini lee-shrimp, silawule uxinano lwe-algae yeseli enye, silungise ukucaca, kwaye sonyuse umxholo we-oksijini enyibilikisiweyo wamanzi echibini lee-shrimp. Ngexesha lobushushu obuphezulu, ukutshintsha amanzi kunokuphola. Ngokongeza nangokutshintsha amanzi, i-pH yamanzi echibini lee-shrimp inokuzinziswa kwaye umxholo wezinto ezinobuthi ezifana ne-hydrogen sulfide kunye ne-ammonia nitrogen unokuncitshiswa, ukuze kubonelelwe ngendawo yokuhlala efanelekileyo yokukhula kwee-shrimp.
