Ukukhuphulai-shrimp, kumele uphakamise amanzi kuqala. Kuyo yonke inqubo yokukhulisa ama-shrimp, ukulawulwa kwekhwalithi yamanzi kubaluleke kakhulu. Ukwengeza nokushintsha amanzi kungenye yezindlela ezilula zokulawula ikhwalithi yamanzi. Ingabe ichibi lama-shrimp kufanele lishintshe amanzi? Abanye abantu bathi ama-prawn abuthakathaka kakhulu. Ukushintsha izimpande ukuze kukhuthazwe ama-prawn ukuba abe yigobolondo kuvame ukwenza buthaka umzimba wawo futhi athambekele ezifweni. Abanye bathi akunakwenzeka ukungashintshi amanzi. Ngemva kwesikhathi eside sokukhulisa, ikhwalithi yamanzi ayishintshi, ngakho-ke kufanele sishintshe amanzi. Ingabe kufanele ngishintshe amanzi enkambisweni yokukhulisa ama-shrimp? Noma ngaphansi kwaziphi izimo amanzi angashintshwa futhi ngaphansi kwaziphi izimo amanzi angeke ashintshwe?

 

Kumelwe kuhlangatshezwane nemibandela emihlanu yokushintsha amanzi ngendlela efanele

1. Ama-prawn awakho esikhathini esiphezuluukubhoboza, futhi umzimba wabo ubuthakathaka kulesi sigaba ukuze bagweme ukucindezeleka okukhulu;

2. Ama-prawn anomzimba onempilo, amandla amahle, ukudla okunamandla futhi awaguli;

3. Umthombo wamanzi uqinisekisiwe, izimo zekhwalithi yamanzi asogwini lolwandle zinhle, izinkomba zomzimba nezamakhemikhali zivamile, futhi akukho mehluko omkhulu kusukela kusawoti kanye nokushisa kwamanzi echibini lezinkawu;

4. Umzimba wamanzi echibini lokuqala unomsoco othile, futhi ulwelwe lunamandla kakhulu;

5. Amanzi okungena ahlungwa nge-mesh ebanzi ukuze kuvinjelwe ngokuqinile izinhlanzi zasendle ezihlukahlukene kanye nezitha ukuthi zingangeni echibini lezimfanzi.

Indlela yokukhipha amanzi nokushintsha amanzi ngokwesayensi kuzo zonke izigaba

1) Isigaba sokuqala sokuzala. Ngokuvamile, amanzi kuphela afakwa ngaphandle kokukhipha amanzi, okungathuthukisa izinga lokushisa kwamanzi ngesikhathi esifushane futhi kukhule izinto eziphilayo ezanele zokudoba kanye nolwelwe oluwusizo.

Uma ufaka amanzi, angahlungwa ngezingqimba ezimbili zezikrini, kanye ne-mesh engu-60 yesendlalelo sangaphakathi kanye ne-mesh engu-80 yesendlalelo sangaphandle, ukuze kuvinjelwe izinto eziphilayo zesitha namaqanda ezinhlanzi ukuthi angangeni echibini le-shrimp. Engeza amanzi angu-3-5cm nsuku zonke. Ngemva kwezinsuku ezingu-20-30, ukujula kwamanzi kungafinyelela kancane kancane ku-1.2-1.5m ukusuka ku-50-60cm yokuqala.

2) Ukuzalanisa isikhathi esimaphakathi. Ngokuvamile, uma umthamo wamanzi udlula u-10cm, akufanele ukushintsha isikrini sesihlungi ukuze kususwe ukungcola nsuku zonke.

3) Isigaba sokugcina sokuzalana. Ukuze kwandiswe umoya-mpilo oncibilikisiwe ongqimbeni olungezansi, amanzi echibini kufanele alawulwe ku-1.2m. Kodwa-ke, ngoSepthemba, izinga lokushisa lamanzi laqala ukwehla kancane kancane, futhi ukujula kwamanzi kungakhushulwa ngendlela efanele ukuze kugcinwe izinga lokushisa lamanzi lihlala linjalo, kodwa ushintsho lwamanzi lwansuku zonke akufanele ludlule u-10cm.

Ngokufaka nokushintsha amanzi, singalungisa usawoti kanye nokuqukethwe kwezakhamzimba emanzini echibini lezinhlanzi, silawule ubuningi be-algae eyodwa, silungise ukucaca, futhi sandise okuqukethwe kwe-oxygen encibilikisiwe emanzini echibini lezinhlanzi. Esikhathini sokushisa okuphezulu, ukushintsha amanzi kungaphola. Ngokufaka nokushintsha amanzi, i-pH yamanzi echibini lezinhlanzi ingaqiniswa futhi okuqukethwe kwezinto ezinobuthi njenge-hydrogen sulfide kanye ne-ammonia nitrogen kungancishiswa, ukuze kuhlinzekwe indawo enhle yokuhlala yokukhula kwezinhlanzi.
