Ukukhula kwe-carp yovavanyo emva kokongeza imilinganiselo eyahlukeneyo yeI-DMPTukuya kwisondlo kubonisiwe kwiThebhile 8. Ngokutsho kweTheyibhile 8, ukondla i-carp kunye noxinzelelo oluhlukeneyoI-DMPTisondlo sandise kakhulu izinga lokufumana ubunzima, izinga lokukhula elithile, kunye nesantya sokuphila xa kuthelekiswa nesondlo sokulawula ukutya, ngelixa i-coefficient yesondlo iyancipha kakhulu. Phakathi kwabo, ubunzima bemihla ngemihla ye-Y2, i-Y3, kunye namaqela e-Y4 ongeziweyo kunye ne-DMPT yanda nge-52.94%, i-78.43%, kunye ne-113.73% ngokulandelanayo xa kuthelekiswa neqela lokulawula. Izinga lokuzuza ubunzima be-Y2, Y3, kunye ne-Y4 yanda nge-60.44%, 73.85%, kunye ne-98.49% ngokulandelanayo xa kuthelekiswa neqela lokulawula, kwaye amazinga athile okukhula anyuke ngo-41.22%, 51.15%, kunye ne-60.31% ngokulandelanayo. Amazinga okuphila onke anyukile ukusuka kwi-90% ukuya kwi-95%, kwaye i-coefficients yokutya yehla.

Ukuphuhliswa kwezinto ezitsala amanzi

Okwangoku, kukho imingeni emininzi ekuvelisweni kwesondlo sasemanzini, phakathi kwayo eyona mingeni mithathu ibalulekileyo:

1. Ukubonelela njani ngesiphumo sokutya kweemveliso zokutya.

2. Indlela yokubonelela ngokuzinza kwemveliso emanzini.

3. Ukunciphisa njani iindleko zemathiriyeli kunye nemveliso.

Ukutya okudliwayo kusisiseko sokukhula kwezilwanyana kunye nophuhliso, iimveliso zesondlo zinefuthe elihle lokutya, ukunambitha okulungileyo, kungekhona nje ukubonelela ngokutya ukutya, ukukhuthaza ukugaywa kwezilwanyana kunye nokufunxa izondlo, ukubonelela ngezondlo ezifunekayo ekukhuleni nasekuphuhliseni, kodwa zinciphisa kakhulu ixesha lokutya, ukunciphisa ilahleko yempahla yeentlanzi kunye nokusetyenziswa kwesondlo.Ukuqinisekisa uzinzo olulungileyo lokutya emanzini ngumlinganiselo ongundoqo wokubonelela ngokusetyenziswa kwesondlo, ukunciphisa ilahleko yokutya kunye nokugcina umgangatho wamanzi echibini.

Indlela yokunciphisa ukutya kunye neendleko zayo zemveliso, kufuneka sifunde kwaye siphuhlise imithombo yokutya efana nezinto ezitsala umtsalane, endaweni yeprotein yezilwanyana kunye neprotheni yezityalo, ukuphucula inkqubo yamaxabiso kunye nothotho lwemilinganiselo yokulinga. Kwi-aquaculture, i-bait eninzi ayizange ithathwe zizilwanyana ukutshona ukuya ezantsi kwamanzi kunzima ukuba ifakwe ngokupheleleyo, ibangele inkunkuma enkulu kuphela, kodwa ingcolise umgangatho wamanzi, ngoko kwi-bait ukongeza izinto ezivuselela ukutya kwezilwanyana -umtsalane wokutyaibaluleke kakhulu.

Ukunyanzeliswa kokutya kunokuvuselela ivumba, incasa kunye nombono wezilwanyana, ukukhuthaza ukukhula kwezilwanyana, kodwa kwakhona ukubonelela ukuxhathisa izifo kunye nokukhuseleka, ukomeleza i-physiologic hulling, ukunciphisa ukungcoliseka kwamanzi kunye nezinye iingenelo.
