Mukuita kurima shrimp muSouth America, varimi vazhinji vanoona kuti shrimp yavo inodya zvishoma nezvishoma uye haimere nyama. Chii chiri chikonzero cheizvi? Kukura kunononoka kwe shrimp kunokonzerwa nembeu ye shrimp, chikafu, uye manejimendi panguva yeaquaculture process.Potassium diformateinogona kugadzirisa dambudziko rekudya zvishoma uye kushayikwa kwekukura kwenyama mukurima shrimp. Vamwe vapfuri vakashuma kuti vakadya zvokudya zvakajairika mumwedzi wokutanga, asi havana kudya zvakawanda mumwedzi wechipiri, zvichiita kuti vapfumi vakawanda vafunge kuti idambudziko nechirauro uye vanofungidzira kuti kusakwana kwechikafu kwaikonzera kuderera kwechikafu cheshrimp uye kuchinja kwemhando yezvokudya. Somugumisiro, mamiriro ekudya anononoka haana kuvandudzika, uye mamwe madziva akatonyanya kuipa.

Kubva pane idzi nyaya, zvikonzero zvekunonoka kudyiwa kweSouth America shrimp zvinogona kupfupikiswa sezvizvi:

1. Chikonzero chembeu yeshrimp:

Imwe mhodzi ye shrimp yakasikwa yehukuru hwakasiyana, uye kukura kwavo kuchave kwakasiyana panguva yekurima gare gare. Kune zvakare mhodzi ye shrimp kubva kwakasiyana masosi, iyo inowanzokura zvishoma nezvishoma kana kumira kukura mune inotevera nhanho.

2. Hunhu hwemvura:

Yakakwira mazinga eammonia nitrogen, nitrite, uye pH mumvura anogona kukonzera pathological shanduko muSouth America shrimp, nekudaro ichikanganisa kudya kwavo.

3. Kune akawanda ma microorganisms mudziva:

inogona kupa zvakawanda zvipenyu zvechirauro kune shrimp, uye nzira yekudya ichanonoka panguva ino.

4. Management zvinhu:

High stocking density, mvura isina kudzika, kusatsinhana kwemvura, uye kusadya kwakakwana (kunowanzodzorwa pa6-8% yehuremu hwemuviri) zvese zvinogona kukonzera kunonoka kudya kweshrimp.

 

Pamusoro pezvinhu zviri pamusoro apa izvo zvinokonzeresa kunonoka shrimp kudya, kune zvakare mabhakitiriya uye zvirwere zvehutachiona. Shrimp nezvirwere zvichanyatsodya zvishoma nezvishoma.

Mhedzisiro ye potassium diformate pakugadzirwa kwekuita kweSouth America shrimp:

Potassium diformateinogona kuderedza chiitiko che enteritis muPenaeus vannamei. Potassium diformate haingogone kuvandudza intestinal permeability, inosimudzira kugaya uye kutora mapuroteni, inosimudzira kukura kweshrimp, asi zvakare inosimudzira colonization uye kuwanda kweanobatsira mabhakitiriya mumatumbo emukati, inhibit intestinal inokuvadza mabhakitiriya, kudzora PH mudumbu remukati, kusimudzira hutano hwemukati, chengetedza intestinal kukura, chengetedza intestinal kukura, chengetedza intestinal kukura. enteritis muPenaeus vannamei, inovandudza zvakanyanya kusadzivirirwa kwe shrimp, kuwedzera kurwisa kwechirwere che shrimp, uye kuvandudza hupenyu hwe shrimp. Mhedzisiro yekuwedzera akasiyana mazinga e potassium diformate kudyisa pakugadzirwa kwekuita kweSouth American white shrimp. Kuwedzera 0.8% potassium diformate pakudya kwakawedzera huremu hweSouth America chena shrimp ne20.6%, uremu hwezuva nezuva ne26%, uye chiyero chekupona ne7.8%. Mhedzisiro yekuedza inoratidza kuti kuwedzera 0.8% nhanho ye potassium diformate kune chikafu cheSouth America chena shrimp inogona kuvandudza zvakanyanya kukura kwe shrimp uye kuwedzera huwandu hwekurarama kwavo.

Basa guru re potassium diformate ndere kuva nemishonga inorwisa mabhakitiriya uye bactericidal, iyo inogona kuvandudza kurwisana kwechirwere che shrimp uye kuwedzera muviri wavo. Zvikamu zvikuru zvepotassium diformateinogona kudzora chimiro chemukati mecobiota uye kuchengetedza kuenzana kwemukati microbiota, iyo inogona kuvandudza kupera kwe shrimp ura, kuwedzera basa reproteases, kuwedzera kugaya uye kushandiswa kweprotein yekudyisa, kuderedza chiyero chekudya, kuvandudza chimiro chekudya che shrimp, uye kukurudzira kukura kwe shrimp.
