Kwinkqubo yokufuya ii-shrimp, abalimi abaninzi badibana nobunzima obulandelayo: umdla wokondla ii-shrimp uyancipha, ukukhula kuyacotha, kwaye kwenzeka nento yokuba "ukutya wedwa akuhlali ixesha elide".

Oku akuchaphazeli nje kuphela iinkcukacha zeeshrimp, kodwa kukwanciphisa ngokuthe ngqo ukusebenza kakuhle kokuzala. Izizathu zale ngxaki ziyinkimbinkimbi kwaye zahlukahlukene, ikakhulu zinxulumene nomgangatho wezityalo zeeshrimp, indawo enamanzi, ulawulo lwezilwanyana zasemanzini, impilo yamathumbu, kunye nosulelo lwezifo.

Izizathu eziphambili zokucotha kokutya kunye nokukhula kwee-shrimp

1. Inkcazelo engalinganiyo yezinto ezibangela ukuqhotsa kwe-shrimp: Ezinye ii-shrimp fry ngokwazo zinobukhulu obahlukeneyo, kwaye amazinga azo okukhula kamva ayahluka ngokwendalo. Umthombo ongaziwayo: Izithole ze-shrimp ezivela kwiifama zezithole ezingekho sesikweni zinokuba nokuwohloka kwezakhi zofuzo okanye zithwale iintsholongwane, nto leyo enokubangela ukuba ukukhula kungakhuli kakuhle okanye izifo kwizigaba zokugqibela.

2. Izinto ezichaphazela umgangatho wamanzi: Ubuninzi be-ammonia nitrogen kunye ne-nitrite emanzini, okanye amaxabiso aphezulu e-pH, anokonakalisa izicubu zegill kunye namalungu okugaya ukutya ee-shrimp, abangele ukusabela koxinzelelo, kwaye athintele ukutya nokukhula.

3. Xa kukho izibayo zendalo ezininzi kakhulu kwaye izilwanyana zeplanktonic (ezifana ne-branchiopods kunye ne-copepods) echibini zininzi kakhulu, ii-shrimp ziya kudla ezi zibayo zendalo, nto leyo ebangela ukuncipha kokutya okwenziwe ngokwenziwa kwaye kudala umbono wokuba ukutya kuhamba kancinci. Ekuhambeni kwexesha, ukukhula kunokucotha ngenxa yokunqongophala kwesondlo.

4. Ulawulo olungafanelekanga kunye noxinano olugqithisileyo lwempahla echibini: ukudlula umthamo wokuthwala amanzi echibini kunokubangela lula iingxaki zoxinzelelo kunye nokhuphiswano olungalinganiyo lokutya. Inqanaba lamanzi angaphantsi: Umzimba wamanzi ubuthathaka kwaye uzinzile, kunye nokuguquguquka okukhulu kobushushu bamanzi kunye noxinzelelo oluqhelekileyo kwi-shrimp

Ukungatshintshisani kwamanzi ngokwaneleyo: Ukuqokelelwa kwenkunkuma ye-metabolism emanzini kunokukhokelela ekuwohlokeni komgangatho wamanzi, okuchaphazela ukondla nokukhula kwee-shrimp.

Ubungakanani bokutya obungenangqiqo: Ngokuqhelekileyo kucetyiswa ukuba ukondle ii-shrimps ngesantya semihla ngemihla se-6% ukuya kwi-8% yobunzima bomzimba wazo (esinokulungiswa ngokulula ngokweqondo lobushushu bamanzi, ioksijini enyibilikisiweyo, kunye neemeko zokutya). Ukondla okunganelanga kunokukhokelela ekuthintelweni kokukhula, ngelixa ukondla ngokugqithisileyo kunokungcolisa ngokulula i-substrate kwaye kwandise umthwalo kwisibindi kunye ne-pancreas.

5. Izinto ezibangela izifo: Izifo zebhaktheriya (ezifana nosulelo lweVibrio) kunye nezifo zentsholongwane (ezifana ne-vitiligo syndrome) zingonakalisa ngokuthe ngqo isibindi, i-pancreas, kunye namathumbu e-shrimp, nto leyo ekhokelela ekunciphiseni kokugaya kunye namandla okufunxa, okudla ngokubonakala njengokunciphisa ukutya okanye ukuyeka ukutya.
Ukonakala kwamathumbu kunye nesisu esingenanto kwi-jejunum zezona zinto ziphambili ezibangela ukulahleka kokutya kwee-shrimp kunye nokuma kokukhula.

Ingaba kwenzeka njanii-potassium diformateukuphucula ingxaki yokondla kancinci kunye nokungabikho kokukhula kwenyama kwi-shrimp

I-Potassium diformatesisilungiselelo se-organic acid esisetyenziswa kakhulu, esakhiwe kakhulu yi-formic acid kunyei-potassium diformateIneempawu zokhuseleko oluluhlaza, ukhuseleko lokulwa neentsholongwane kunye namathumbu, ukukhuthaza ukukhula okusebenzayo, kwaye ayinantsalela okanye ukumelana namayeza, nto leyo ehlangabezana neemfuno zokufuywa kwezilwanyana zasemanzini eziluhlaza.
Ngokuphathelele imiba yokondla nokukhula kwe-shrimp yaseMzantsi Melika, indlela esebenza ngayo ibonakala kakhulu kwezi zinto zilandelayo:

1. Ukuphucula impilo yamathumbu.I-Potassium diformateinokulawula ixabiso le-pH yamathumbu, ithintele ukwanda kweebhaktheriya eziyingozi (ezifana neebhaktheriya eziqhelekileyo ezibangela izifo ezifana neVibrio), kwaye ikhuthaze ukwanda kweebhaktheriya eziluncedo ezifana neebhaktheriya ze-lactic acid, igcine ibhalansi ye-microbiota yamathumbu kwaye inciphise ngempumelelo ukwenzeka kwe-enteritis.

2. Ukuphucula umsebenzi wee-enzyme zokugaya ukutya kunye nokukhuthaza ukusetyenziswa kweeproteni ngokuphucula ukungena kwamathumbu.I-Potassium diformateinokuphucula umsebenzi weeproteases kunye nezinye ii-enzymes zokugaya ukutya, ikhuthaze ukuqhekeka kunye nokufunxwa kweeproteni ekutyeni, ngaloo ndlela inyuse izinga lokuguqulwa kokutya, inciphise ukusebenza kakuhle kokutya (umlinganiselo wokutya), kwaye inciphise inkunkuma yezakhamzimba.

3. Uphuculo olukhulu ekusebenzeni kokukhula kunye nezinga lokusinda. Izifundo ezenziwe zizazi zaseTshayina uHe Suxu et al. (2006) zibonise ukuba ukongeza i-0.8%i-potassium diformateUkwanda kobunzima be-shrimp emhlophe yaseMzantsi Melika kunokunyusa ubunzima be-shrimp iyonke nge-20.6%, ukunyuka kobunzima bemihla ngemihla nge-26%, kunye nezinga lokusinda nge-7.8%. Iziphumo zophando zibonisa ukuba i-potassium formate inokuphucula imeko yokondla ye-shrimp kwaye ikhuthaze ukukhula komntu ngamnye.

4. Ukutya okuzinzileyo kunye nokunciphisa impendulo yoxinzelelo.I-Potassium diformateinokuphucula imeko yamathumbu kunye nemeko yempilo iyonke yeeshrimp, izincede zikwazi ukumelana ngcono noxinzelelo lwendalo olufana nokuguquguquka komgangatho wamanzi, uxinzelelo loxinano, kunye noxinzelelo lwezifo, ngaloo ndlela zigcina indlela yokutya ezinzileyo kwaye zinciphise ukungafuni ukutya okubangelwa luxinzelelo.

Iingcebiso

Xa abalimi bedibana neemeko apho ukutya kwee-shrimp kuhamba kancinci kwaye bengakhulisi nyama, kufuneka baqale bajonge umgangatho wezithole zee-shrimp, izalathisi zomgangatho wamanzi, ubuninzi bempahla, kunye nokuba zikhona na izifo, baze balungise isicwangciso solawulo ngokufanelekileyo ngokusekelwe kwimeko yokwenyani emlonyeni wechibi.

Kwangaxeshanye, i-potassium formate yesayensi ingasetyenziswa ekutyeni (nceda ujonge imiyalelo yemveliso ukuze ufumane idosi ethile, kwaye uhlengahlengise ngokuguquguqukayo ngokweenkcukacha zee-shrimp kunye nendawo yokuzalela). Ukusetyenziswa kwexesha elide nokufanelekileyo kunokunceda ukugcina impilo yamathumbu, ukuphucula ukusetyenziswa kokutya, kwaye ekugqibeleni kufezekise injongo "yokukhulisa ii-shrimp ezinkulu nezilungileyo".

Ukugcina amathumbu eeshrimp kubalulekile ekutyeni okuzinzileyo, ekukhuleni kwenyama ngokukhawuleza, ekuphuculweni kweenkcukacha, nasekunyuseni inzuzo.
