Kusimudzashrimp, unofanira kutanga wasimudza mvura.Mukuita kwese kwekusimudza shrimp, kudzora kwemhando yemvura kwakakosha zvikuru.Kuwedzera nekushandura mvura ndiyo imwe yenzira dzakareruka dzekugadzirisa kunaka kwemvura.Ko shrimp dziva rinofanira kuchinja mvura here?Vamwe vanhu vanoti prawn haina kusimba.Kuchinja mizongoza kuti prawns iite goko kazhinji inonetesa muviri uye inotapukira kuzvirwere.Vamwewo vanoti hazvibviri kusachinja mvura.Mushure menguva yakareba yekusimudza, hutano hwemvura huri eutrophic, saka tinofanira kuchinja mvura.Ndinofanira kushandura mvura mukugadzira shrimp?Kana kuti mumamiriro ezvinhu api mvura inogona kuchinjwa uye pasi pemamiriro api mvura haigoni kuchinjwa?

 

Mamiriro mashanu achasangana kuitira shanduko yemvura inonzwisisika

1. Maprawn haasi munguva yepamusoro yeshelling, uye muviri wavo hauna simba panguva ino kuti udzivise kushungurudzika kwakanyanya;

2. Maprawn ane muviri une hutano, ane simba rakanaka, kudya kwakasimba uye haana chirwere;

3. Chitubu chemvura chinovimbiswa, mamiriro emvura ekumahombekombe egungwa akanaka, zvinyorwa zvepanyama uye zvemakemikari zvakajairika, uye pane musiyano muduku kubva mumunyu uye kupisa kwemvura mumvura ye shrimp;

4. Mvura yedhamu rekutanga ine imwe mbereko, uye algae ine simba rakati;

5. Mvura inopinza inonatswa neine dense mesh kudzivirira zvakasimba hove dzesango dzakasiyana-siyana uye vavengi kupinda mu shrimp pond.

Nzira yekudhonza nekushandura mvura nesainzi padanho rega rega

1) Danho rekutanga rekuberekesa.Kazhinji, mvura chete inowedzerwa pasina mvura, iyo inogona kuvandudza tembiricha yemvura munguva pfupi uye kurima zvakakwana zvipenyu zvechirauro uye algae inobatsira.

Paunenge uchiwedzera mvura, inogona kusefa nezvikamu zviviri zvemasikirini, ine 60 mesh yemukati yemukati uye 80 mesh kune yekunze layer, kuitira kudzivirira zvisikwa zvevavengi nemazai ehove kupinda mudziva re shrimp.Wedzera mvura ye3-5cm zuva nezuva.Mushure memazuva 20-30, kudzika kwemvura kunogona kusvika zvishoma nezvishoma kusvika 1.2-1.5m kubva pakutanga 50-60cm.

2) Kuberekesa kwenguva yepakati.Kazhinji, kana huwandu hwemvura huchipfuura 10cm, hazvina kukodzera kushandura sefa sikirini kuti ubvise tsvina zuva rega rega.

3) Gare gare nhanho yekuberekesa.Kuti uwedzere okisijeni yakanyungudika muzasi, mvura yedziva inofanira kudzorwa pa 1.2m.Zvisinei, munaSeptember, kutonhora kwemvura kwakatanga kudonha zvishoma nezvishoma, uye kudzika kwemvura kunogona kuwedzerwa zvakakodzera kuchengetedza tembiricha yemvura nguva dzose, asi kuchinja kwemvura kwezuva nezuva hakufaniri kudarika 10cm.

Nekuwedzera uye nekushandura mvura, tinogona kugadzirisa salinity uye zvinovaka muviri zviri mumvura mune shrimp pond, kudzora density ye unicellular algae, kugadzirisa pachena, uye kuwedzera iyo yakanyungudika yeokisijeni yemvura mu shrimp pond.Munguva yekushisa kwepamusoro, kuchinja mvura kunogona kutonhora pasi.Nekuwedzera nekuchinja mvura, iyo pH yemvura mu shrimp pond inogona kudzikamiswa uye zviri muchetura zvinhu zvakaita sehydrogen sulfide uye ammonia nitrogen zvinogona kuderedzwa, kuitira kuti ipe nzvimbo yakanaka yekugara yekukura kwe shrimp.
