Uphando lwamva nje kwimakethi yokutya okuneentsiba ekhutshwe nguPhando lweMarike eSelubala lubandakanya uhlalutyo lweshishini lehlabathi kunye novavanyo lwamathuba ka-2020-2030.Ngo-2020, imakethi yehlabathi yokutya iintsiba iya kwenza ingeniso ye-359.5 yezigidi zeedola zaseMelika, kunye nesantya sokukhula esiqikelelwayo sonyaka se-8.6%, kwaye siya kufikelela kwi-820 yezigidi zeedola zaseMelika ngo-2030.
Fumana ukutya okuphuma kwimveliso yezilwanyana ukumisela ifuthe lemathiriyeli ekrwada kunye neemeko zokusetyenzwa ekuphunyukeni kweprotheyini, ukugaywa kweprotheyini kunye namanye amanyathelo okuchaza ixabiso lesondlo.Ukutya okuneentsiba kwimizi yokucoca kuyimveliso ebalulekileyo yenkukhu.Ukutya okuneentsiba kwimizi yokucoca kuyimveliso ebalulekileyo yenkukhu.Inkunkuma yeentsiba evela kwisebe lokulungisa iinkukhu ekugqibeleni ingasetyenziswa njengomthombo weprotheyini kwinkqubo yokutya kwezilwanyana.Iintsiba zityebile kwiprotheyini ebizwa ngokuba yikeratin, eyenza i 7% yobunzima beentaka eziphilayo, ngoko ke zibonelela ngomthamo omkhulu wezinto ezinokuguqulwa zibe kukutya okuxabisekileyo.Ukongeza, xa kuthelekiswa nokutya kwe-oyile, ukusetyenziswa kwesidlo sentsiba njengowona mthombo ubalaseleyo weprotein yokuphunyuka kuya konyusa imfuno yentengiso yokutya kweentsiba.
Kule minyaka imbalwa idlulileyo, abavelisi bezondlo zasemanzini baye banomdla kakhulu kukutya kweentsiba.Njengomthombo weprotheyini, ukutshintshwa kwesidlo sentlanzi kwisondlo se-aquaculture kunenzuzo engenakuphikiswa: inexabiso lezondlo kungekhona kuphela kwimixholo yeprotheyini kunye nokugaya, kodwa nangokwezoqoqosho.Ngumthombo obaluleke kakhulu weprotheyini kwisondlo se-aquaculture, kwaye ibonise ukusebenza okugqwesileyo kunye namanqanaba aphezulu okubandakanywa kwizifundo kunye novavanyo lwezorhwebo.Iziphumo zabonisa ukuba ukutya okunentsiba kunesondlo esilungileyo kwitrout, kwaye ukutya kwentlanzi kungasetyenziswa kunye nomgubo wenkukhu ophuma kwimveliso ngaphandle kokulahleka kokukhula, ukutya okutyiwayo okanye ukondla ngokufanelekileyo.Ingaba ukutya okuneentsiba kukutya kwekhaphu kufanelekile ukuthatha indawo yeprotein yokutya kwentlanzi kuya kwandisa imfuno yokutya kweentsiba.
Njengenzuzo ebalulekileyo, ulimo lwendalo oludityaniswe zizichumisi eziphilayo luselubhejo olunengeniso kushishino lwezolimo oluphuhlayo.Njengoko ukutya kwe-organic kuya kuthandwa ngakumbi, lukhetho olukhuselekileyo nolusesikweni kubathengi.Ukongeza kwiindlela zokuziphatha, izichumisi eziphilayo nazo zifumene uphuhliso olukhulu ngenxa yokwanda kolwakhiwo lomhlaba kunye nokugcinwa kwamanzi kunye nezinye izibonelelo ezininzi zokusingqongileyo.Ukuqonda kwabalimi malunga neenzuzo zesondlo kwizichumisi ezisekelwe kwizityalo kunye nezilwanyana kunye nendima yabo ekukhuthazeni ukukhula komhlaba kunye neminye imisebenzi ye-microbial esekelwe kwizityalo iye yaqhubeka ikhula, nto leyo eye yakhuthaza ukwamkelwa kwezichumisi eziphilayo.Ekubeni izichumisi zemveliso yezilwanyana eziphilayo zinee-adsorbents ezilungileyo kunye namandla okubamba amanzi, oko kunokwandisa ukuchuma komhlaba, kunomtsalane ngakumbi kuneentlobo zezityalo.
Ukuze isetyenziswe kwimveliso yezityalo eziqinisekisiweyo eziphilayo, iintlobo ezininzi zezichumiso ezithengiswayo zingasetyenziswa.Ezi mveliso ziquka i-shrimp elulwelo, isichumiso esifakwe kwi-pelleted senkukhu, i-guano pellets evela kwiintaka zaselwandle, i-nitrate yaseChile, iintsiba kunye nokutya kwegazi.Iintsiba ziyaqokelelwa kwaye zibekwe kubushushu obuphezulu kunye noxinzelelo, kwaye emva koko zigaywe zibe ngumgubo ocolekileyo.Emva koko zipakishwa ukuze zisetyenziswe kwimixube yesichumiso, ukutya kwezilwanyana, kunye nokunye ukutya emva kokoma.Ukutya okunentsiba kuqulethe izichumisi zenitrogen ezininzi, ezinokuthatha indawo yezichumiso zolwelo ezininzi zokwenziwa efama.
Nangona imfuno yokutya kwezilwanyana ibizinzile, ingxaki ye-coronavirus ibethe kakhulu.Ngenxa yamanyathelo aqatha ethathiweyo ukuqulatha ubhubhani we-Covid-19, i-China, njengomboneleli ophambili weembotyi zesoya eziphilayo, ibangele iingxaki kubavelisi bezondlo zendalo.Ukongeza, ngenxa yemicimbi yezothutho e-China kunye nokuthuthwa kwamanye amacandelo omkhondo, ukufumaneka kwezikhongozeli kunye neenqanawa nazo ziyachaphazeleka.Oorhulumente bayalele ukuvalwa ngokuyinxenye kwamazibuko wabo wamazwe ngamazwe, nto leyo ephazamisa ngakumbi ikhonkco lokubonelela ngesondlo sezilwanyana.
Ukuvalwa kweendawo zokutyela kuyo yonke imimandla kulichaphazele kakhulu ishishini lokutya kwezilwanyana.Ngokujonga ukuqhambuka kwe-COVID-19, utshintsho olumandla kwiipateni zokusetyenziswa kwabathengi lunyanzelise abavelisi ukuba baphinde baqwalasele imigaqo-nkqubo kunye nezicwangciso zabo.Imveliso yeenkukhu kunye nokulima emanzini ngawona macandelo achaphazelekayo.Oku kuya kuchaphazela ukukhula kweemarike zokutya kweentsiba kwi-1-2 iminyaka, kwaye kulindeleke ukuba imfuno iya kuwela unyaka omnye okanye emibini, kwaye ifike kwimeko emileyo kwiminyaka embalwa ezayo.
