Ukukhula kwe-carp yovavanyo emva kokongeza amazinga ahlukeneyo e-I-DMPTukutyiwa kwenyama kuboniswe kwiTheyibhile 8. NgokweTheyibhile 8, ukondla i-carp enomlinganiselo owahlukeneyo we-I-DMPTUkutya kunyuse kakhulu izinga labo lokunyuka kwesisindo, izinga lokukhula elithile, kunye nezinga lokusinda xa kuthelekiswa nokutya okulawulayo, ngelixa i-coefficient yokutya yehla kakhulu. Phakathi kwabo, ukunyuka kwesisindo kwemihla ngemihla kwamaqela e-Y2, Y3, kunye ne-Y4 okongeziweyo nge-DMPT kunyuke nge-52.94%, 78.43%, kunye ne-113.73% ngokulandelelana xa kuthelekiswa neqela lolawulo. Amazinga okunyuka kwesisindo e-Y2, Y3, kunye ne-Y4 anyuke nge-60.44%, 73.85%, kunye ne-98.49% ngokulandelelana xa kuthelekiswa neqela lolawulo, kwaye amazinga okukhula athile anyuke nge-41.22%, 51.15%, kunye ne-60.31% ngokulandelelana. Amanqanaba okusinda onke anyuke ukusuka kwi-90% ukuya kwi-95%, kwaye ii-coefficients zokutya zehla.

Uphuhliso lwezinto ezitsala amanzi

Okwangoku, kukho imingeni emininzi kwimveliso yokutya kwasemanzini, phakathi kwayo kukho imingeni emithathu ebaluleke kakhulu:

1. Indlela yokubonelela ngesiphumo sokondla seemveliso zokutya.

2. Indlela yokuqinisekisa uzinzo lwemveliso emanzini.

3. Indlela yokunciphisa iindleko zezinto ezikrwada kunye nemveliso.

Ukutya okutyiwayo sisiseko sokukhula nophuhliso lwezilwanyana, iimveliso zokutya zinefuthe elihle lokutya, ziyathandeka, azinakubonelela ngokutya kuphela, zikhuthaze ukugaywa nokufunxwa kwezondlo zezilwanyana, zibonelela ngezondlo ezifunekayo ekukhuleni nasekuphuhliseni, kodwa zikwanciphisa kakhulu ixesha lokutya, zinciphise ukulahleka kwezinto zokutya kweentlanzi kunye nokusetyenziswa kokutya.Ukuqinisekisa uzinzo olufanelekileyo lokutya emanzini yindlela ephambili yokubonelela ngokusetyenziswa kokutya, ukunciphisa ukulahleka kokutya kunye nokugcina umgangatho wamanzi edamini usemgangathweni.

Indlela yokunciphisa ukutya kunye neendleko zako zemveliso, kufuneka sifunde kwaye siphuhlise izixhobo zokutya ezifana nezinto ezitsala ukutya, sitshintshe iiproteni zezilwanyana ngeproteni yezityalo, siphucule inkqubo yexabiso kunye nothotho lwamanyathelo okuzama. Kwi-aquaculture, uninzi lwezithako ezingakhange zithathwe zizilwanyana ukuze zitshone ezantsi kwamanzi kunzima ukuziginya ngokupheleleyo, azibangeli nje kuphela inkunkuma enkulu, kodwa zingcolisa umgangatho wamanzi, ngoko ke kwizithako ukongeza izinto ezivuselela umdla wezilwanyana -into enomtsalane wokutyakubaluleke kakhulu.

Ukutya okubangela umdla kunokuvuselela ivumba, incasa kunye nombono wezilwanyana, kukhuthaze ukukhula kwezilwanyana, kodwa kukwabonelela ngokumelana nezifo kunye nokuzikhusela komzimba, komeleze ukujikeleza kwemizimba, kunciphise ungcoliseko lwamanzi kunye nezinye izibonelelo.
