Kukwezashirimpi, uyenera kutunga madzi kaye.Pantchito yonse yoweta shrimp, kuwongolera madzi ndikofunikira kwambiri.Kuonjezera ndi kusintha madzi ndi imodzi mwa njira zosavuta zoyendetsera madzi abwino.Kodi dziwe la shrimp liyenera kusintha madzi?Anthu ena amanena kuti prawns ndi zofooka kwambiri.Kusintha kwa nsana kuti prawns ikhale chipolopolo nthawi zambiri kumafooketsa thupi lawo ndipo sachedwa kudwala.Ena amati n’zosatheka kusasintha madzi.Pambuyo pa nthawi yayitali yokweza, madzi abwino ndi eutrophic, kotero tiyenera kusintha madzi.Kodi ndisinthe madzi ndikuweta shrimp?Kapena mumikhalidwe yotani madzi angasinthidwe ndipo pansi pazifukwa zotani madzi sangasinthidwe?

 

Zinthu zisanu ziyenera kukwaniritsidwa kuti madzi asinthe

1. Akalulu sali m'nthawi yapamwamba yakuponya zipolopolo, ndipo thupi lawo ndi lofooka panthawiyi kuti apewe kupsinjika kwakukulu;

2. Akalulu amakhala ndi thupi lathanzi, amphamvu, amadya mwamphamvu komanso alibe matenda;

3. Gwero la madzi ndilotsimikizika, mikhalidwe yamadzi a m'mphepete mwa nyanja ndi yabwino, zizindikiro zakuthupi ndi zamankhwala ndizodziwika bwino, ndipo pali kusiyana pang'ono ndi mchere ndi kutentha kwa madzi mu dziwe la shrimp;

4. Madzi a dziwe loyambirira amakhala ndi chonde, ndipo ndere zimakhala zolimba;

5. Madzi olowera amasefedwa ndi mesh wandiweyani kuti aletse kuti nsomba zakuthengo zosiyanasiyana komanso adani asalowe mu dziwe la shrimp.

Momwe mungakhetsere ndikusintha madzi mwasayansi pagawo lililonse

1) Nthawi yoberekera koyambirira.Nthawi zambiri, madzi okha amawonjezedwa popanda ngalande, zomwe zimatha kusintha kutentha kwa madzi mu nthawi yaifupi ndikukulitsa zamoyo zokwanira za nyambo ndi algae opindulitsa.

Powonjezera madzi, amatha kusefedwa ndi zigawo ziwiri za zowonetsera, ndi ma mesh 60 amkati ndi ma mesh 80 akunja, kuti ateteze zamoyo za adani ndi mazira a nsomba kuti asalowe mu dziwe la shrimp.Onjezerani madzi 3-5cm tsiku lililonse.Pambuyo pa masiku 20-30, kuya kwa madzi kumatha kufika pang'onopang'ono mpaka 1.2-1.5m kuchokera ku 50-60cm yoyambirira.

2) Kuswana kwa nthawi yapakatikati.Nthawi zambiri, kuchuluka kwa madzi kukapitilira 10cm, sikoyenera kusintha sefa kuti muchotse zonyansa tsiku lililonse.

3) Gawo lotsatira la kuswana.Kuti muwonjezere mpweya wosungunuka pansi, madzi a dziwe ayenera kuyendetsedwa pa 1.2m.Komabe, mu September, kutentha kwa madzi kunayamba kutsika pang'onopang'ono, ndipo kuya kwa madzi kungawonjezeke moyenera kuti madzi asatenthedwe, koma kusintha kwa madzi tsiku ndi tsiku sikudzapitirira 10cm.

Powonjezera ndi kusintha madzi, titha kusintha mchere ndi michere m'madzi mu dziwe la shrimp, kuwongolera kachulukidwe ka algae unicellular, kusintha kuwonekera, ndikuwonjezera mpweya wosungunuka m'madzi mu dziwe la shrimp.M'nyengo yotentha kwambiri, kusintha madzi kumatha kuzizira.Powonjezera ndi kusintha madzi, pH ya madzi mu dziwe la shrimp imatha kukhazikika komanso zomwe zili ndi poizoni monga hydrogen sulfide ndi ammonia nitrogen zitha kuchepetsedwa, kuti pakhale malo abwino okhalamo kuti shrimp ikule.
