Enkambisweni yokufuya ama-shrimp aseNingizimu Melika, abalimi abaningi bathola ukuthi ama-shrimp abo adla kancane futhi awakhulisi inyama. Iyini imbangela yalokhu? Ukukhula kancane kwama-shrimp kungenxa yembewu, ukudla, kanye nokuphathwa kwama-shrimp ngesikhathi senqubo yokufuya izinhlanzi.I-Potassium diformatekungaxazulula inkinga yokondla kancane kanye nokuntuleka kokukhula kwenyama ekulimeni izimfanzi. Abanye abafuyi babike ukuthi badla ukudla okuvamile ngenyanga yokuqala, kodwa abadlanga kakhulu ngenyanga yesibili, okwenza abafuyi abaningi bacabange ukuthi kwakuyinkinga ngesicupho futhi basola ukuthi ikhwalithi embi yokondla yayibangela ukwehla kwesifiso sokudla izimfanzi kanye noshintsho ohlotsheni lokondla. Ngenxa yalokho, isimo sokondla kancane asizange sithuthuke, futhi amanye amachibi aba bucayi nakakhulu.

Ngokusekelwe kulezi zinkinga, izizathu zokusetshenziswa kancane kwe-shrimp yaseNingizimu Melika zingafingqwa kanje:

1. Isizathu sembewu ye-shrimp:

Ezinye imbewu ye-shrimp ngokwemvelo zinobukhulu obuhlukene, futhi ukukhula kwazo kuzohluka ngesikhathi sokutshala kamuva. Kukhona nembewu ye-shrimp evela emithonjeni ehlukene, evame ukukhula kancane noma iyeke ukukhula esigabeni sokugcina.

2. Ikhwalithi yamanzi:

Amazinga aphezulu e-ammonia nitrogen, i-nitrite, kanye ne-pH emanzini angabangela izinguquko ezingokwempilo kuma-shrimp aseNingizimu Melika, ngaleyo ndlela athinte ukudla kwawo.

3. Kunezinhlobo eziningi zezinambuzane echibini:

ingahlinzeka ngezinhlobo eziningi zezinhlanzi ezidla ukudla okudliwayo, futhi inqubo yokudla izohamba kancane ngalesi sikhathi.

4. Izici zokuphatha:

Ubuningi obukhulu bama-stock, izinga lamanzi angajulile, ukushintshana kwamanzi okunganele, kanye nokudla okunganele (ngokuvamile okulawulwa ngo-6-8% wesisindo somzimba) konke kungabangela ukudla okuhamba kancane kwama-shrimp.

 

Ngaphezu kwezici ezingenhla ezibangela ukondla kancane kwe-shrimp, kukhona nezifo ezibangelwa amagciwane kanye nezifo. I-shrimp enezifo nakanjani izodla kancane.

Umphumela we-potassium diformate ekusebenzeni kahle kokukhiqizwa kwezinhlanzi zaseNingizimu Melika:

I-Potassium diformatekunganciphisa izinga lokusabalala kwe-enteritis ePenaeus vannamei. I-Potassium diformate ayikwazi nje ukuthuthukisa ukungena kwamathumbu, ikhuthaze ukugaya kanye nokumuncwa kwamaprotheni, ikhuthaze ukukhula kwe-shrimp, kodwa futhi ikhuthaze ukwakheka kwama-bacteria awusizo kanye nokwanda kwamagciwane awusizo endleleni yamathumbu, ivimbele amagciwane ayingozi emathunjini, ilawule i-PH endleleni yamathumbu, ikhuthaze ukuthuthukiswa kwamathumbu, igcine impilo yamathumbu e-shrimp, inciphise kakhulu izinga lokusabalala kwe-enteritis ePenaeus vannamei, ithuthukise kakhulu ukuzivikela kwe-shrimp, ikhulise ukumelana kwesifo se-shrimp, futhi ithuthukise amandla e-shrimp. Umphumela wokwengeza amazinga ahlukene e-potassium diformate ukuze ondle ukusebenza kokukhiqizwa kwe-shrimp emhlophe yaseNingizimu Melika. Ukwengeza i-potassium diformate engu-0.8% ekudleni kwandisa isisindo esiphelele se-shrimp emhlophe yaseNingizimu Melika ngo-20.6%, inzuzo yesisindo yansuku zonke ngo-26%, kanye nesilinganiso sokusinda ngo-7.8%. Imiphumela yokuhlola ikhombisa ukuthi ukwengeza izinga lika-0.8% le-potassium diformate ekudleni kwe-shrimp emhlophe yaseNingizimu Melika kungathuthukisa kakhulu ukukhula kwe-shrimp futhi kwandise izinga lokusinda kwazo.

Umsebenzi oyinhloko we-potassium diformate ukuba nemiphumela yokulwa namagciwane kanye ne-bactericidal, okungathuthukisa ukumelana kwe-shrimp nezifo futhi kuthuthukise ukuqina komzimba wazo. Izingxenye eziyinhloko ze-potassium diformatei-potassium diformateingalawula ukwakheka kwe-intestinal microbiota futhi igcine ibhalansi ye-intestinal microbiota, okungathuthukisa ukungena kwamathumbu e-shrimp, kwandise umsebenzi we-proteases, kwandise ukugaya nokusetshenziswa kweprotheni yokudla, kunciphise isilinganiso sokudla, kuthuthukise isimo sokudla kwe-shrimp, futhi kukhuthaze ukukhula kwe-shrimp.
