Ukukhula kwe-carp yokuhlola ngemuva kokwengeza ukugxila okuhlukile kweI-DMPTkuya okuphakelayo kukhonjiswe kuThebula 8. Ngokusho kweThebula 8, ukondla inhlazi yasemfuleni ngokugxila okuhlukene kweI-DMPTokuphakelayo kukhulise kakhulu izinga lokukhula kwesisindo, izinga elithile lokukhula, nezinga lokusinda uma kuqhathaniswa nokuphakelayo kokulawula ukudla, kuyilapho i-coefficient yokuphakelayo yehla kakhulu. Phakathi kwabo, inzuzo yesisindo sansuku zonke ye-Y2, Y3, kanye namaqembu e-Y4 angezwe nge-DMPT akhuphuke ngo-52.94%, 78.43%, no-113.73% ngokulandelanayo uma kuqhathaniswa neqembu lokulawula. Izinga lokuzuza kwesisindo se-Y2, Y3, ne-Y4 likhuphuke ngo-60.44%, 73.85%, no-98.49% ngokulandelanayo uma kuqhathaniswa neqembu lokulawula, futhi amazinga athile okukhula akhuphuke ngo-41.22%, 51.15%, no-60.31% ngokulandelana. Amazinga okusinda wonke anyuke ukusuka ku-90% kuya ku-95%, futhi ama-coefficients okuphakelayo ehla.

Ukuthuthukiswa kwezinto ezikhangayo zasemanzini

Njengamanje, kunezinselelo eziningi ekukhiqizweni kokuphakela kwamanzi, phakathi kwazo okuyizinselelo ezintathu ezibalulekile yilezi:

1. Indlela yokuhlinzeka ngomphumela wokondla wemikhiqizo yokudla.

2. Indlela yokuhlinzeka ngokuzinza komkhiqizo emanzini.

3. Unganciphisa kanjani izindleko zempahla nezindleko zokukhiqiza.

Ukudla okuphakelayo kuyisisekelo sokukhula nokuthuthukiswa kwezilwane, imikhiqizo yokudla inomphumela omuhle wokondla, ukunambitheka okuhle, hhayi nje kuphela okunganikeza ukudla okudliwayo, ukukhuthaza ukugaya kwezilwane nokumuncwa kwezakhi, ukunikeza izakhi eziningi ezidingekayo ekukhuleni nasekuthuthukisweni, kodwa futhi kufinyeze kakhulu isikhathi sokudla, ukunciphisa ukulahlekelwa kwezinto ezibonakalayo zezinhlanzi zokudla kanye nokusetshenziswa kokudla.Ukuqinisekisa ukuzinza okuhle kokuphakelayo emanzini kuyisinyathelo esibalulekile sokuhlinzeka ngokusetshenziswa kokuphakelayo, ukunciphisa ukulahleka kokuphakelayo kanye nokugcina ikhwalithi yamanzi echibini.

Indlela yokunciphisa ukudla kanye nezindleko zako zokukhiqiza, kudingeka sifunde futhi sithuthukise izinsiza zokuphakelayo ezifana nezinto eziheha ukudla, simisele amaprotheni ezilwane esikhundleni samaprotheni ezitshalo, sithuthukise inqubo yamanani kanye nochungechunge lwezinyathelo zokuhlola. Ngo aquaculture, eziningi isiheho engakaze kuthathwe izilwane ukucwila phansi emanzini kunzima ukugwinya ngokugcwele, hhayi kuphela kubangele imfucuza enkulu, kodwa futhi ungcolise izinga lamanzi, ngakho ku lolo ukwengeza inkanuko isilwane ukudla izinto -ukuheha ukudlakubaluleke kakhulu.

Ukuncenga ukudla kungavusa iphunga, ukunambitheka kanye nombono wezilwane, kukhuthaze ukukhula kwezilwane, kodwa futhi kunikeze ukumelana nezifo nokuvikeleka, kuqinise i-physiologic hulling, ukunciphisa ukungcoliswa kwamanzi nezinye izinzuzo.
