Macrobrachium rosenbergii inoparadzirwa zvakanyanyashrimp yemvura yakachenanehuwandu hwekudya kunovaka muviri uye kudiwa kukuru kwemusika.

Nzira huru dzekurera dzeRoche shrimpzviri sezvinotevera:
1. Single aquaculture: kureva, kungorima Roche shrimp mumvura imwe chete yemvura uye kwete dzimwe mhuka dzomumvura. Zvakanakira zvemhando yekurima iyi manejimendi akareruka uye purofiti yakakwira, asi zvisungo ndezvemhando yepamusoro yemvura inodiwa, kuitika nyore kwezvirwere uye kudyidzana.
2. Mixed aquaculture: zvinoreva kurimwa kweRoche shrimp nedzimwe mhuka dzemumvura dzakadai sehove, snails, clams, nezvimwewo mumvura imwe chete yemvura. Kubatsira kweiyo aquaculture modhi ndeyekushandisa iyo yakawanda-layered nzvimbo yemuviri wemvura, kuvandudza goho remvura, kuwedzera mari inowanikwa, uye kuderedza kukwikwidza uye kupambwa pakati peRoche shrimp, nekudaro kuderedza kuitika kwezvirwere. Asi chakashata ndechekuti manejimendi akaomesesa, uye kutariswa kunofanirwa kubhadharwa pakusarudzwa uye chikamu chemarudzi ekuberekesa kudzivirira kufurirana uye kubata chikafu.

3. Crop rotation aquaculture: inoreva kurimwa kweProcambarus clarkii nedzimwe mhuka dzemumvura mumvura imwe chete yemvura maererano neimwe nguva inotevedzana, sekurima shrimp muminda yemupunga uye kurima hove muminda yemupunga. Kubatsira kweiyi modhi yezvemvura ndeyekushandisa zvizere shanduko yemwaka mumitumbi yemvura, kuwana mabhenefiti maviri ezvigadzirwa zvemumvura nezvirimwa, ukuwo uchivandudza nharaunda yezvisikwa zvemitumbi yemvura uye kuderedza kuitika kwezvirwere. Asi chakashata ndechekuti panofanirwa kutariswa kurongeka kwembeu kuitira kudzivirira kupindirana pamwe nekukanganisa pakati pezvigadzirwa zvemumvura nezvirimwa.

Zvakanakira uye Zvinetso zveRoche Shrimp Kurima Tekinoroji:

1. Zvakanakira zveRoche shrimp kurima tekinoroji zvinonyanya zvinosanganisira zvinotevera:
Roche shrimp chinhu chepamusoro-chinokosha chemvura chigadzirwa chine hutano hwepamusoro uye kudiwa kwemusika, izvo zvinogona kuunza hupfumi hwehupfumi.
2. Roche shrimp imhuka yeomnivorous ine chikafu chakakura, chinogona kushandisa chikafu chepanyama uye chepamusoro-soro chezvo mumvura kuti kuderedze mari yekuberekesa.
3. Roche shrimp imhuka inogadziriswa zvikuru ine mararamiro akasiyana-siyana ehupenyu uye salinity, uye inogona kugadzirwa mumvura yakasiyana-siyana yemvura, ichiwedzera kushanduka kwemvura.
4. Roche shrimp imhuka inokurumidza kukura ine nguva shoma yekukura uye goho rakakwirira, izvo zvinogona kupfupisa nguva yekuberekesa uye kuvandudza kubudirira kwekubereka.
5. Roche shrimp imhuka inokodzera kurima kwakasanganiswa uye kurima kutenderedza zvirimwa, iyo inogona kubatsiridza dzimwe mhuka dzemumvura uye zvirimwa, kuvandudza kubereka kwemvura, uye kubudirira kwakasiyana siyana kweaquaculture nekurima.
Zvinetso zveRoche shrimp kurima tekinoroji zvinonyanya zvinosanganisira zvinotevera:
1. Roche shrimp imhuka ine zvinodiwa zvemhando yepamusoro yemvura, uye kukura kwayo uye kukura kunokonzerwa zvikuru nehutano hwemvura. Zvakakosha kusimbisa kutarisa kwehutano hwemvura uye kutonga kudzivirira kusvibiswa kwemvura uye kuora.
2. Roche shrimp imhuka inobatwa nezvirwere, ine utachiona hushoma uye inobatwa nezvirwere zvakadai sebhakitiriya, mavhairasi, fungi, uye utachiona. Nokudaro, zvakakosha kusimbisa kudzivirira nekudzivirira zvirwere kuderedza kufa uye kurasikirwa kweRoche shrimp.
3. Roche shrimp imhuka inowanzosangana, ine misiyano yakakura muhuwandu hwepabonde uye kukura kwemuviri, izvo zvinogona kutungamirira kumakwikwi uye kurwisa pakati pehombe dzechirume. Nokudaro, zvakakosha kusimbisa kutonga kwehutano hwepabonde uye kufanana kwekukura kwemuviri kuderedza kukakavara uye kukuvara pakati peRoche shrimp.
4. Roche shrimp imhuka inokonzerwa nekushanduka kwemusika, uye mutengo wayo uye kudiwa kunosiyana nemwaka nematunhu. Izvo zvinodikanwa kusimbisa kuferefetwa kwemusika uye ongororo, kugadzira inonzwisisika chiyero chekubereka uye zvinangwa, uye kudzivirira kugovera-kuda kusaenzana uye kuderera kwemutengo.

DMPT (Dimethyl - β - Propionate Thiophene) ine zvinotevera zvakakosha zvakanakira mune zvemumvura, kunyanya mukurima shrimp:

1. Kuvandudza kudya kwekudya
DMPT inowedzera zvakanyanya kuwanda kwekudyisa uye kumhanya, inopfupisa nguva yekudya, uye inoderedza tsvina yekudya nekukurudzira shrimp's olfactory uye gustatory receptors. Tsvagiridzo yakaratidza kuti kuwedzera DMPT kudyisa kunogona kuwedzera huwandu hwekushandisa ne25% -30% uye kuderedza njodzi yekusvibiswa kwemvura. .
Kurudzira kukura uye molting.
2. DMPT inogona kukurumidza kunyunguduka kwe shrimp uye kupfupisa kutenderera kwekukura. Zvichakadaro, chimiro chayo chine sarufa chinogona kusimudzira amino acid metabolism, kuvandudza kushandiswa kweamino acid, uye kuwedzera kuwedzera kushanda zvakanaka. .
3. Kuwedzera kunaka kwenyama uye kukosha kwehupfumi.

4. DMPT inogona kuvandudza nyama inonaka ye shrimp, ichipa shrimp yemvura yakachena inonaka uye inotapira yakafanana neyegungwa shrimp, kuwedzera kukwikwidza kwemusika. .

5. Kuchengetedza uye Kuchengetedzwa Kwezvakatipoteredza.

6. DMPT shrimp haina chepfu, ine yakasara yakasara, uye inosangana nezvinodiwa zvegreen aquaculture.
