Kusimudzashrimp, unofanira kutanga wasimudza mvura. Mukuita kwese kwekurera shrimp, kudzora kunaka kwemvura kwakakosha zvikuru. Kuwedzera nekuchinja mvura ndeimwe yenzira dziri nyore dzekugadzirisa kunaka kwemvura. Dziva reshrimp rinofanira kuchinja mvura here? Vamwe vanhu vanoti prawns hadzina kusimba. Kuchinja misana kuti ikukurudzire shrimps kuita goko kunowanzo deredza muviri wavo uye kunowanzobatwa nezvirwere. Vamwe vanoti hazvigoneke kusachinja mvura. Mushure menguva yakareba yekurera, kunaka kwemvura kunobva muropa, saka tinofanira kuchinja mvura. Ndinofanira kuchinja mvura here mukurera shrimp? Kana kuti mvura inogona kuchinjwa mumamiriro api ezvinhu uye mvura haigone kuchinjwa mumamiriro api ezvinhu?

 

Zvinodiwa zvishanu zvinofanira kuzadzikiswa pakuchinja mvura zvine musoro

1. Makamba haasi munguva yekupisa zvakanyanyakupfura, uye muviri wavo hauna simba panguva ino kudzivirira kushushikana kwakanyanya;

2. Magamba ane muviri wakanaka, ane simba, anodya zvine simba uye haana chirwere;

3. Mvura inobuda inovimbiswa, mamiriro emvura ari pedyo negungwa akanaka, huwandu hwemvura inobuda mumuviri nemakemikari hwakajairwa, uye hapana musiyano mukuru kubva mumunyu nekupisa kwemvura mudziva remashrimp;

4. Mvura yedziva rekutanga ine mwero wakati, uye algae yacho yakasimba zvishoma;

5. Mvura inopinzwa inoseferwa nemesh yakakora kudzivirira hove dzakasiyana-siyana dzemusango nevavengi kuti vasapinde mudziva remashrimp.

Maitiro ekubvisa mvura nekuchinja mvura nesainzi muchikamu chimwe nechimwe

1) Danho rekutanga kubereka. Kazhinji, mvura chete ndiyo inowedzerwa pasina kudonhedza mvura, izvo zvinogona kuwedzera tembiricha yemvura munguva pfupi uye kukura kwezvipembenene zvakakwana zvechitsotsi uye algae inobatsira.

Kana mvura ikawedzerwa, inogona kuseferwa nezvikamu zviviri zvemasefa, ine mesh 60 yemukati uye mesh 80 yekunze, kuitira kudzivirira zvisikwa zvevavengi nemazai ehove kuti asapinde mudziva rema shrimp. Wedzera mvura kwe3-5cm zuva rega rega. Mushure memazuva 20-30, kudzika kwemvura kunogona kusvika zvishoma nezvishoma 1.2-1.5m kubva pa50-60cm yekutanga.

2) Kubereka kwembeu kwenguva yepakati. Kazhinji, kana huwandu hwemvura hwapfuura 10cm, hazvina kukodzera kuchinja sikirini yekusefa kuti ibvise tsvina zuva nezuva.

3) Danho rekupedzisira rekubereka. Kuti mvura yedziva iwedzere okisijeni yakanyungudika pasi, mvura yedziva inofanira kudzorwa pa 1.2m. Zvisinei, munaGunyana, tembiricha yemvura yakatanga kudonha zvishoma nezvishoma, uye kudzika kwemvura kunogona kuwedzerwa zvakakodzera kuti tembiricha yemvura irambe yakafanana, asi kuchinja kwemvura zuva nezuva hakufanirwe kudarika 10cm.

Nekuwedzera nekuchinja mvura, tinogona kugadzirisa munyu uye huwandu hwezvinovaka muviri mumvura mudziva remashrimp, kudzora huwandu hwealgae imwe chete, kugadzirisa kujeka, uye kuwedzera huwandu hweokisijeni yakanyungudutswa mumvura mudziva remashrimp. Munguva yekupisa kwakanyanya, kuchinja mvura kunogona kutonhora. Nekuwedzera nekushandura mvura, pH yemvura mudziva remashrimp inogona kugadzikana uye huwandu hwezvinhu zvine chepfu zvakaita sehydrogen sulfide neammonia nitrogen hunogona kuderedzwa, kuitira kuti pave nenzvimbo yakanaka yekugara yekukura kwemashrimp.
