Mhinduro yaPenaeus vannamei kune yakashandurwa mamiriro ezvakatipoteredza inonzi "stress response", uye shanduko yemhando dzakasiyana dzemuviri nemakemikari indexes mumvura zvese zvinoshungurudza zvinhu.Apo shrimps inopindura kune kuchinja kwezvinhu zvakatipoteredza, simba ravo rekudzivirira muviri richaderedzwa uye simba rakawanda remuviri richapedzwa;Kana shanduko yemhando yekunetsekana isiri yakakura uye nguva isiri refu, shrimp inogona kurarama nayo uye haizokonzeri kukuvadza kukuru;Pane zvinopesana, kana nguva yekushungurudzika yakanyanyisa, shanduko yakakura, kunze kwekugadziriswa kwe shrimp, shrimp icharwara kana kufa.

Ⅰ.Zviratidzo zve shrimp stress reaction zvaive zvinotevera

1. Ndebvu dzvuku, muswe mutsvuku fan uye muviri mutsvuku we shrimp (inowanzozivikanwa sekutambudzika muviri mutsvuku);

2. Chengetedza zvakanyanya zvinhu, kunyangwe usadye zvinhu, shambira uchitevedza dziva

3. Zviri nyore kusvetukira mudziva

4. Yellow gills, black gills uye akatyoka ndebvu zviri nyore kuonekwa.

Ⅱ, Zvikonzero zvekupindura kwekushushikana kweprawn zvaive zvinotevera:

1. Algae phase mutation: zvakadai sekufa kamwe kamwe kwealgae, ruvara rwemvura yakachena kana kuwandisa kwealgae, uye ruvara rwemvura yakanyanyisa;

2. Kuchinja kwemamiriro ekunze, zvakadai semamiriro ekunze akaoma akadai semhepo inotonhora, dutu, mvura inoramba ichinaya, mvura inonaya, zuva rine makore, kusiyana kukuru kwekushisa pakati pechando nekupisa: mvura inonaya uye inonaya inoramba ichinaya ichaita kuti mvura inonaya iungane pamusoro pemvura ye shrimp pond.Mushure memvura, tembiricha yemvura yepamusoro yakadzikira uye tembiricha yemvura yepasi yakakwira, izvo zvinokonzeresa convection yemvura, uye nhamba huru yephotosynthesis algae inofa (kuchinja kwemvura) nekuda kwekushaikwa kwe photosynthesis algae.Mumamiriro ezvinhu aya, mvura inosangana ne hypoxia yakaoma;Iyo micro ecological balance yemuviri wemvura yakatyoka, uye tupukanana tunokuvadza tinopararira muhuwandu hwakawanda (mvura inova chena uye turbid), izvo zvinoita kuti nyore nyore iyo organic matter iri pazasi pedziva iparare uye ibudise hydrogen sulfide uye nitrite muanaerobic state uye. fomu kuunganidza, izvo zvinokonzeresa chepfu uye kufa kwe shrimp.

3. Kuchinja kwezvinyorwa zvemuviri uye zvemakemikari mumuviri wemvura: kuchinja kwekushisa kwemvura, kujeka, pH kukosha, ammonia nitrogen, nitrite, hydrogen sulfide uye zvimwe zviratidzo zvichaitawo kuti prawn ibudise mhinduro yekushungurudzika.

4. Solar term replacement: nekuda kwekuchinja kwemazwi ezuva, mamiriro ekunze asingatarisike, kusiyana kukuru kwekushisa uye kusava nechokwadi kwemhepo, shanduko inogara kwenguva yakareba, izvo zvinoita kuti zvinhu zvemuviri nemakemikari emvura ye shrimp zvishanduke zvikuru, izvo zvinokonzera. kushushikana kwakasimba kwe prawn kukonzeresa kubuda kwehutachiona uye hombe-yakawanda pond drainage.

5. Kushandiswa kwezvipembenene zvinokurudzira, algal zvinodhaka zvakadai semhangura sulfate, zinc sulfate, kana chlorine ine mishonga inouraya utachiona inogona kuunza kushushikana kwakasimba kune prawn.

Ⅲ, Kudzivirira uye kurapwa kwekushushikana kwekuita

1. Hunhu hwemvura netsvina zvinofanirwa kuvandudzwa nguva nenguva kudzivirira kutsauka kwemvura;

Kuwedzera kwekabhoni sosi kunogona kuvandudza kunaka kwemvura uye kudzivirira algae kudonha.

2. Muchiitiko chemhepo ine simba, dutu, kutinhira, zuva remvura, mhepo yekuchamhembe uye mamwe mamiriro okunze akaipa, kudya kunofanira kuwedzerwa kumvura yemvura munguva yekudzivirira kuitika kwekunetseka kwepfungwa;

3. Huwandu hwekuwedzera hwemvura haufanire kunge hwakanyanya, kazhinji nezve 250px yakakodzera.Zvigadzirwa zveAnti stress zvinogona kushandiswa kudzikamisa kuita kwekushushikana;

4. Nyatsocherechedza kushanduka kwemamiriro ekunze nguva dzose, uye shandisa anti-stress products kugadzirisa kunaka kwemvura munguva.

5. Mushure mehombe yakawanda, prawns inofanira kuwedzerwa ne calcium munguva kuti iite yakaoma shelled nokukurumidza uye kuderedza kushungurudzika.
