Imboni yezinhlanzi zokuhlobisa yaseJapan, esekelwa yiNishikigoi eyaziwa emhlabeni wonke (i-koi carp), imele indawo ephezulu emkhakheni wezokufuya izilwane zasemanzini obanzi. IJapan yathumela kwamanye amazwe cishe amathani angu-560 ezinhlanzi zokuhlobisa eziphilayo ngo-2024, kanti i-koi ibiza ngaphezu kwama-80% enani lokuthumela kwamanye amazwe ngokusho kwedatha yokuhweba yoMnyango Wezolimo, Amahlathi Nezokudoba yaseJapan. Imakethe yokudla kwe-koi yasekhaya—elinganiselwa kumathani ayi-12,000 kuya ku-15,000 ngonyaka—idinga imishini yokugaya ama-pellet ekwazi ukukhiqiza ama-pellet antantayo anokubekezelelana okuqondile kobubanzi, ukuqina kwamanzi okuphezulu, kanye nokulingana kwezakhamzimba okuhambisanayo phakathi kwama-pellet amaningi asukela ku-2 mm kuya ku-8 mm.

Lolu cwaningo luhlola indlela umenzi wokudla kwe-koi eNiigata Prefecture, indawo yokuzalwa yokuzalanisa i-Nishikigoi, athole ngayo ukuthuthuka okulinganiselwe kwekhwalithi yama-pellet kanye nokusebenza kahle kokukhiqiza ngemuva kokusebenzisa imishini yokugaya i-Hongyang HYPM ring die pellet yomugqa wayo wokudla kwezinhlanzi zokuhlobisa. Esikhathini sokusebenza sezinyanga ezingu-14, umshini uqophe isikhathi sokusebenza esingu-98.3%, ukuphambuka kosayizi wama-pellet ngaphansi kuka-0.15 mm, kanye nokuqina kwamanzi okungaphezu kwamahora angu-4—izilinganiso ezisekela ngqo amazinga aqinile abafuyi be-koi abangochwepheshe baseJapan kanye nabantu abathanda ukuzilibazisa ngokufanayo.

Ingemuva: Imboni Yokudla Kwe-Koi yaseJapan

Imboni yaseNishikigoi yaseJapan isekelwe eNiigata Prefecture, lapho ukufuywa kwe-carp enemibala kwaqala khona ekuqaleni kwekhulu le-19 esifundeni saseYamakoshi. Namuhla, iJapane ibamba abafuyi be-koi ababhalisiwe abangaphezu kuka-1,500, ikakhulukazi abagxile ezifundeni zaseNiigata, eHiroshima, naseFukuoka. Imakethe ye-koi yasekhaya inenani elilinganiselwa kuma-yen ayizigidi eziyizinkulungwane ezingu-30 ngonyaka, kanti izinhlobo zekhwalithi yokubonisa ngayinye zibiza amanani asukela kuma-yen angu-500,000 kuya kuma-yen angaphezu kwezigidi eziyi-100 endalini.

Le makethe enenani eliphezulu ibeka izidingo ezingavamile kwikhwalithi yokudla. Ama-Koi ayaziswa ngenxa yobukhulu bombala wawo, ukucaca kwephethini, ukukhanya kwesikhumba, kanye nokwakheka komzimba—zonke izici ezithonywa ngqo ukudla okunomsoco. Ukwakheka kokudla kwe-koi okuphezulu okumelelayo kuqukethe ukudla kwenhlanzi okungu-35-40% wesabelo, ufulawa kakolweni ongu-15-20% osebenza njengomthombo wama-carbohydrate kanye ne-binder yemvelo, ukudla kwesoya okungu-10-15%, i-rice bran engu-5-10%, i-spirulina engu-3-5% yokuthuthukisa umbala osekelwe ku-carotenoid, ukudla kwe-krill okungu-3-5% njengomthombo wemvelo we-astaxanthin, kanye ne-premix yamavithamini namaminerali kufaka phakathi i-vitamin C ezinzile yokusebenza komzimba.

Izimpawu zomzimba zama-pellets okuphakelwa yi-koi nazo zinzima kakhulu. Ama-pellets antantayo kumele ahlale ethambile okungenani imizuzu engama-30 ukuze kuvunyelwe ukubonwa kokudla—umkhuba obalulekile ekufuyeni ama-koi lapho abafuyi behlola khona ngokubonakalayo ukuziphatha kokudla njengesibonakaliso esiyinhloko sempilo yezinhlanzi. Ububanzi bama-pellet busukela ku-2 mm kuma-tosai amancane (inhlanzi enonyaka owodwa) kuya ku-8 mm kuma-jumbo koi avuthiwe angaphezu kwama-80 cm ubude. Ngaphakathi kwesigaba ngasinye sosayizi, ukubekezelela ububanzi akumele kudlule ku-±0.2 mm ukuqinisekisa ukudla okufanayo nokuvimbela ukuncintisana okusekelwe kusayizi ngaphakathi kwamachibi. Ukuqina kwamanzi—okulinganiswa njengoba ubude bama-pellets buhlala buphelele ngaphandle kokuqhekeka—kumele kudlule amahora ama-2 ukuvimbela ukungcola kwamanzi echibini, okuthi ezinhlelweni zokufuya zasemanzini ezivaliwe ezingakhuphula ngokushesha amazinga e-ammonia futhi kucindezele isitoko senani eliphezulu.

Iklayenti: Uchwepheshe Wokuphakelayo Kwe-Koi Osekelwe eNiigata
