Uphando lwamva nje kwimarike yesidlo seentaka olukhutshwe yiTransparency Market Research lubandakanya uhlalutyo lweshishini lehlabathi kunye novavanyo lwamathuba ngo-2020-2030. Ngo-2020, imakethi yesidlo seentaka yehlabathi iya kuvelisa ingeniso ye-359.5 yezigidi zeerandi zaseMelika, kunye nezinga lokukhula eliqikelelweyo lonyaka le-8.6%, kwaye iya kufikelela kwi-820 yezigidi zeerandi zaseMelika ngo-2030.
Fumana isidlo semveliso yezilwanyana ukuze ubone impembelelo yezinto eziluhlaza kunye neemeko zokucubungula ekuphumeni kweproteni, ukugaywa kweproteni kunye nezinye iindlela zokulinganisa ixabiso lokutya. Isidlo seentsiba esivela kwiindawo zokucoca sisiphumo esibalulekileyo senkukhu. Isidlo seentsiba esivela kwiindawo zokucoca sisiphumo esibalulekileyo senkukhu. Inkunkuma yeentsiba evela kwicandelo lokucubungula iinkukhu ekugqibeleni ingasetyenziswa njengomthombo weproteni kwinkqubo yokondla izilwanyana. Iintsiba zizityebi kwiproteni ebizwa ngokuba yi-keratin, ebanga i-7% yobunzima beentaka eziphilayo, ngoko ke zibonelela ngobuninzi bezinto ezinokuguqulwa zibe kukutya okuxabisekileyo. Ukongeza, xa kuthelekiswa nomgubo weoyile, ukusetyenziswa komgubo weentsiba njengomthombo obalaseleyo weproteni yokuphuma kuya kwandisa imfuno yemarike yomgubo weentsiba.
Kwiminyaka embalwa edlulileyo, abavelisi bezondlo zasemanzini baye baba nomdla ngakumbi kwisidlo seentsiba. Njengomthombo weproteni, ukutshintsha isidlo seentlanzi kwisondlo sezilwanyana zasemanzini kunenzuzo engenakuphikiswa: inexabiso lesondlo kungekuphela nje ngokubhekiselele kumxholo weproteni kunye nokugaywa, kodwa nakwimeko yezoqoqosho. Ngumthombo oxabisekileyo kakhulu weproteni kwisondlo sezilwanyana zasemanzini, kwaye ibonakalise ukusebenza kakuhle ngamanqanaba aphezulu okubandakanywa kwizilingo zezemfundo nezezorhwebo. Iziphumo zibonise ukuba isidlo seentsiba sinexabiso elifanelekileyo lesondlo kwi-trout, kwaye isidlo seentlanzi singasetyenziswa kunye nesidlo semveliso yenkukhu ngaphandle kokulahlekelwa kukusebenza kokukhula, ukutya okutyiwayo okanye ukusebenza kakuhle kokutya. Nokuba isidlo seentsiba kwisondlo se-carp sifanelekile na ukuthatha indawo yeproteni yesidlo seentlanzi kuya kwandisa imfuno yokutya kweentsiba.
Njengenzuzo ebalulekileyo, ulimo lwendalo oluqulathe izichumisi zendalo luseyinzuzo enkulu kushishino lwezolimo olusakhulayo. Njengoko ukutya kwendalo kusanda kuthandwa, lukhetho olukhuselekileyo nolunemigaqo yokuziphatha kubathengi. Ukongeza kwimigaqo yokuziphatha, izichumisi zendalo zikwafumene uphuhliso olukhulu ngenxa yokwanda kwesakhiwo somhlaba kunye nokugcinwa kwamanzi kunye nezinye izibonelelo ezininzi zokusingqongileyo. Ukuqonda kwabalimi ngeenzuzo zesondlo zezichumisi ezisekwe kwizityalo nezilwanyana kunye nendima yazo ekukhuthazeni ukukhula komhlaba kunye neminye imisebenzi yeentsholongwane ezisekwe kwizityalo kuqhubekile nokukhula, nto leyo eye yakhuthaza ukwamkelwa kwezichumisi zendalo. Ekubeni izichumisi eziphuma kwizilwanyana zendalo zinee-adsorbents ezilungileyo kunye namandla okugcina amanzi, nto leyo enokuphucula ukuchuma komhlaba, inomtsalane ngakumbi kuneentlobo ezisekwe kwizityalo.
Ukuze zisetyenziswe ekuveliseni izityalo ezivunyiweyo zendalo, iintlobo ezininzi zezichumisi zendalo zorhwebo zingasetyenziswa. Ezi mveliso ziquka i-shrimp engamanzi, isichumisi seenkukhu esifakwe iipellet, iipellets ze-guano ezivela kwiintaka zaselwandle, i-nitrate yaseChile, iipellets kunye nomgubo wegazi. Iipellets ziyaqokelelwa kwaye zibekwe kubushushu obuphezulu kunye noxinzelelo, emva koko zicutshungulwe zibe ngumgubo ocolekileyo. Emva koko zipakishwa ukuze zisetyenziswe kwimixube yezichumisi, ukutya kwezilwanyana, kunye nokunye ukutya emva kokuba komile. Umgubo weepepper uqulethe izichumisi zendalo ezine-nitrogen eninzi, ezinokuthatha indawo yezichumisi ezininzi zolwelo ezenziweyo efama.
Nangona imfuno yokutya kwezilwanyana izinzile, ingxaki ye-coronavirus ichaphazele kakhulu ukunikezelwa. Ngenxa yamanyathelo aqatha athathiweyo ukunqanda ubhubhane we-Covid-19, iTshayina, njengomthengisi omkhulu weembotyi zesoya eziphilayo, ibangele iingxaki kubavelisi bezondlo eziphilayo kwihlabathi liphela. Ukongeza, ngenxa yeengxaki zothutho eTshayina kunye nokuthuthwa kwezinye izinto ezilandelelanayo, ukufumaneka kwezikhongozeli kunye neenqanawa nako kuyachaphazeleka. Oorhulumente bayalele ukuvalwa okuncinci kwamazibuko abo aphesheya, ngaloo ndlela bephazamisa ngakumbi ukuhanjiswa kokutya kwezilwanyana.
Ukuvalwa kweendawo zokutyela kuzo zonke iindawo kuye kwayichaphazela kakhulu imboni yokutya kwezilwanyana. Ngenxa yokuqhambuka kwe-COVID-19, utshintsho olukhulu kwiindlela zokusetyenziswa kwabathengi luye lwanyanzela abavelisi ukuba baphinde baqwalasele imigaqo-nkqubo kunye namaqhinga abo. Imveliso yeenkukhu kunye nokufuywa kwezilwanyana zasemanzini zezona candelo zichaphazeleka kakhulu. Oku kuya kuchaphazela ukukhula kwemarike yesidlo seentsiba iminyaka eli-1 ukuya kwemi-2, kwaye kulindeleke ukuba imfuno yehle unyaka omnye okanye emibini, ize ifikelele kwimeko yokuma kwayo kwiminyaka embalwa ezayo.
