Izindlela Zokukhetha Imbewu Yenhlanzi Ephakeme
Impumelelo yokufuya izinhlanzi inqunywa kakhulu kusukela esigabeni sokuqala, okungukuthi ukukhethwa kwembewu. Imbewu yezinhlanzi engcono kakhulu izokhula ngokushesha, imelane kakhulu nezifo, ibe nesilinganiso esiphakeme sokusinda, futhi ikhiqize isivuno esifanayo. Ngokuphambene nalokho, imbewu esezingeni eliphansi ivame ukuba yimbangela enkulu yokukhula kancane, ukufa okuphezulu, kanye nezindleko zokukhiqiza ezikhulayo ngenxa yokwanda kokudla nezidingo zokwelashwa . Ngakho-ke, ukukhethwa kwembewu akukhona nje ukukhetha izinhlanzi "ezibukeka zinkulu," kodwa inqubo yokuhlola ephelele esekelwe ezindinganisweni zezinto eziphilayo, impilo, ukufana, kanye nemvelaphi yembewu.
1. Imvelaphi Ecacile Nethembekile Yembewu
Indlela yokuqala yokuthola imbewu engcono kakhulu umthombo ocacile. Imbewu kufanele ivele endaweni yokuchamisela noma kumhlinzeki othembekile onerekhodi elihle kanye nemikhuba efanele yokuphatha imfuyo kanye nezibungu. Imvelaphi ecacile ivumela abalimi ukulandelela ikhwalithi yezakhi zofuzo, umlando wokugoma noma wokwelashwa (uma kusebenza), kanye nezindinganiso zokupakisha nokuthumela.
Uma kungenzeka, khetha imbewu equkethe ulwazi olufana nobudala, uhlobo noma uhlobo (isb., i-Nile tilapia, i-Sangkuriang catfish, i-Siamese catfish, njll.), umlando wokudla, kanye nezimo zamanzi ezivamile ezisetshenziswa endaweni yokuchamisela. Lolu lwazi lubalulekile ukunciphisa ukucindezeleka ngesikhathi sokuzivumelanisa nendawo yokulima.
2. Isimo Sempilo: Siyasebenza, Sishesha, Futhi Siyasabela
Ama-fish fry amahle kakhulu ngokuvamile ayasebenza futhi ayasabela ezicini. Uma isitsha sinyakaziswa kancane noma kufakwe inani elincane lokudla, ama-fish fry anempilo azosabela ngokushesha futhi abhukude kancane kancane. Lesi sici sibonisa uhlelo lwezinzwa nemisipha olusebenza kahle kanye nesimo somzimba senhlanzi esihle kakhulu.
Ngakolunye uhlangothi, ama-fry abuthakathaka avame ukubhukuda kancane, ahlale eyedwa, ahlale phansi, noma ahlangane ebusweni ngokunyakaza okungajwayelekile. Ukuziphatha kokuphefumula ebusweni kuvame ukukhombisa izinkinga zokuphefumula, ikhwalithi yamanzi ephansi , noma izinkinga ze-gill. Ukukhetha ama-fry ngokuziphatha okuvamile kuyindlela elula kodwa ephumelela kakhulu yokunciphisa ingozi yokufa ngaphambi kwesikhathi.
3. Ukuma komzimba okulinganayo nokungaphelele
Ukuhlola okubonakalayo kuyisici esibalulekile sokukhetha. Izinhlanzi ezinhle kakhulu zinomzimba ohambisana nohlobo lwazo, azigobile, azinazo izinkinga zomgogodla, zinamaphiko aphelele, futhi azinawo amanxeba avulekile. Naka okulandelayo:
– Umgogodla uqondile, awugobile (kyphosis/scoliosis).
– Amaphiko aphelele, awadabukile noma avaliwe njalo.
– Umlomo ojwayelekile, akukho zinkinga eziphazamisa ikhono lokudla.
– Isisu asivamile, asivuvukele kakhulu (okubonisa izinkinga zokugaya ukudla) futhi asicwili kakhulu (okubonisa ukungadli kahle noma ubuthakathaka).
Ukukhubazeka ngokomzimba akugcini nje ngokunciphisa inani lemakethe kodwa futhi kuvame ukuhlotshaniswa nokukhula okungekuhle kanye nokuthambekela ezifweni. Amachwane anenkinga angaholela nasekudleni inyama noma alahlekelwe ukuncintisana ngokudla.
4. Imibala Egqamile Nefanayo Ngokohlobo
Umbala womzimba we-fry uyisibonakaliso sempilo yabo. I-superior fry ngokuvamile inombala ogqamile, ayiphaphathekile, futhi ayinazo izindawo ezingavamile. Kwezinye izinhlobo zezinhlanzi, izinguquko zombala zingathonywa ukucindezeleka noma indawo ezungezile ithangi. Kodwa-ke, kunezimpawu okufanele uziqaphele, njenge:
– Amabala amhlophe afana nosawoti (okuholela ebaleni elimhlophe).
– Ukubomvu phansi kwezimpiko noma umzimba (kubonisa ukutheleleka noma ukucasuka).
– Ulwelwesi noma umzimba ogcwele ubukeka ubuthakathaka (kubonisa izimuncagazi noma ikhwalithi yamanzi ephansi).
Ukufana kombala nakho kubalulekile ngoba kuvame ukuhlotshaniswa nokufana kwezimo kanye nekhwalithi yokugcinwa esigabeni sokutshala.
5. Usayizi Ofanayo Wokunciphisa Ukungalingani Kokukhula
Imbewu enhle kakhulu ayigcini nje ngokuba nkulu, kodwa futhi iyafana phakathi kwabantu. Ukufana ngobukhulu kunciphisa ukuncintisana ngokudla, kunciphisa ukucindezeleka, futhi, ikakhulukazi kwezinye izinhlanzi (njenge-catfish), kunganciphisa ingozi yokudla inyama. Ukungafani kobukhulu nakho kwenza kube nzima ukuphathwa kokudla: izinhlanzi ezinkulu zizobusa ukutholakala kokudla, kuyilapho izinhlanzi ezincane zizoshiywa ngemuva futhi zibe buthakathaka.
Kungcono kakhulu, khetha imbewu enobukhulu obufanayo kanye nesisindo ephaketheni elilodwa. Uma imbewu isivele ihluka, yibeke ezingeni (yihlele ngobukhulu) kusenesikhathi ukuze uthuthukise ukusebenza kokutshala.
6. Isimo Esijwayelekile Se-Gill kanye Nokuphefumula Okuzinzile
Ama-gill yizitho ezibalulekile ezivame ukuba yizo eziqala ukuhlushwa lapho ama-fry ecindezelekile noma evezwa emanzini aphansi . Ama-fry amahle kakhulu ane-gill ebomvu ekhanyayo (hhayi onsundu, aphuzi, noma amnyama) futhi awanayo i-mucus eningi. Ukuvulwa nokuvalwa kwe-operculum (i-gill flap) nakho kuyinto evamile, akusheshi kakhulu noma kuyanyakaza.
Uma kungenzeka, yenza ukuhlola okulula ngokubheka amasampula ambalwa. Ukuphefumula okusheshayo kakhulu kungabonisa ukucindezeleka, ukuntuleka komoya-mpilo oncibilikile, noma ukuba khona kwezinambuzane ezidla izimbotshana.
7. Akukho Zifo Namagciwane: Ukuhlolwa Okulula Nokuhlukaniswa
Imbewu enhle kakhulu kufanele ivele ezindaweni ezinezinyathelo zokuphepha kwezinto eziphilayo, ngaleyo ndlela kunciphisa ingozi yezifo. Kodwa-ke, empeleni, abalimi kusadingeka baqaphele. Ngaphezu kokubuka ngokomzimba, ukuhlola okulula kungenziwa ngokunaka:
– ukuba khona kwamanxeba, izilonda, noma isikhunta esifana nekotini;
– umzimba uvame ukukhuhla izindonga zesitsha (ukukhanya), okubonisa ukuthi kunezinambuzane;
– indle ende emhlophe (okubonisa izinkinga ezithile zokugaya ukudla).
Isinyathelo esingcono kakhulu ngemva kokuthenga imbewu ukuzihlukanisa ngaphambi kokuzifaka echibini elikhulu. Ukuzihlukanisa kusiza ekumiseni ukudluliswa kwezifo futhi kuvumela isikhathi sokuzivumelanisa nezimo. Ukuzihlukanisa kuvumela abalimi ukuthi babheke noma yikuphi ukufa okungajwayelekile noma ukubonakala kwezimpawu zesifo.
8. Isifiso Sokudla Esihle Nokuphendula Okusheshayo Kokudla
Imbewu enhle kakhulu ivame ukuba nesifiso sokudla esihle. Uma inikezwa ukudla okuvivinywayo (uma kungenzeka), imbewu enempilo izodla kalula futhi inyakaze ngenkuthalo. Impendulo enhle yokudla ikhombisa impilo enhle ye-metabolic kanye nethuba lokukhula ngokushesha.
Ukungathandi ukudla kungabangelwa ukucindezeleka okubangelwa ukuhamba, kodwa uma kuqhubeka isikhathi eside noma kuhambisana nezinye izimpawu, kuwuphawu lwekhwalithi ephansi . Ngokukhetha imbewu eshesha ukondliwa, isikhathi sokululama ngemva kokuhlwanyela sizoba sifushane.
9. Ukumelana Nokucindezeleka Nokuzivumelanisa Nemvelo
Imbewu engcono kakhulu iyakwazi ukuzivumelanisa kangcono nezinguquko zemvelo. Ekulimeni, izinguquko ekushiseni, i-pH, kanye nekhwalithi yamanzi kungenzeka ngesikhathi sokuthutha noma ukushintsha kwesitsha. Imbewu enamandla cishe ayifi ngesikhathi senqubo yokugcina isitokwe.
Ngakho-ke, ngaphezu kokukhetha imbewu enempilo, abalimi kufanele basebenzise ukuzijwayeza: ukulinganisa izinga lokushisa nokulungisa kancane kancane amanzi avela esikhwameni/esitsheni sokuthutha aye emanzini echibi. Imbewu esezingeni eliphezulu izobonisa impendulo yokuzivumelanisa nezimo eqinile, ngeke yesabe ngokweqile, futhi ngeke intante kakhulu ngemva kokukhululwa.
10. Izinto Ezicatshangelwayo Zofuzo kanye Nezinhloso Zokulima
Kumabhizinisi angathi sína, ikhwalithi yembewu incike nasezicini zofuzo. Imbewu enhle ivela kubazali abahle, ekhethwe ngokusekelwe ekukhuleni okusheshayo, ukusebenza kahle kokudla, ukumelana nezifo, kanye nokufana. Ukukhetha uhlobo olufanele kufanele kuhambisane nezinhloso zokulima: ukusetshenziswa, ukukhula okusheshayo, noma ukukhiqizwa kwemfuyo.
Uma umgomo wakho wokulima uwukuvuna okusheshayo, khetha imbewu ohlelweni lokukhetha olubeka phambili izinga lokukhula. Uma indawo yokulima ithambekele ezifweni ezithile, beka phambili imbewu eyaziwa ngokuthi imelana kakhulu. Ukufaneleka kwembewu ezimweni zendawo (izinga lokushisa, ukuphakama, uhlobo lwamanzi) nakho kuthinta kakhulu umphumela wokugcina.
Isiphetho
Ukukhetha imbewu yezinhlanzi engcono kakhulu kuyisisekelo sokutshala okuphumelelayo. Izindlela ezibalulekile zifaka phakathi imvelaphi ecacile, inhlanzi enempilo nesebenzayo, ukuma komzimba okuvamile okungenamaphutha, umbala okhanyayo, usayizi ofanayo, ama-gill ajwayelekile, inhlanzi engenazifo, isifiso sokudla okuhle, kanye nokuzivumelanisa nezimo okuphezulu. Ngaphezu kwakho konke, imbewu kumele ifaneleke ekutshalweni okuhlosiwe kanye nezimo zemvelo zendawo. Ngokusebenzisa ukukhetha ngokucophelela kusukela ekuqaleni, abalimi banganciphisa ukufa, bandise ukukhula, futhi bazuze isivuno esihle nesinenzuzo.
