Ukulima kwe-Catfish eNingizimu Afrika kunamandla amakhulu, kepha abalimi abasha bamanzi kumele babe nesimiso esihle sokumaketha ngaphambi kokuba baqale.

Indlela Yokufuya Izinhlanzi ze-Catfish

Yokuthi bakwazi ukusebenzisa umoya ngokuqondile njengomthombo wabo we-oksijeni, kanye nokubekezelela kwabo izinga elibi lamanzi elizogxilisa izinhlanzi ezibucayi ezibucayi, i-catfish ingahlwanyiswa kakhulu. Lezi zinhlobo zemvelo ezishisayo futhi zikhule kahle ekushiseni kwamanzi okungama-28°C. Ngaphansi kwezimo zasezindaweni ezishisayo zihlonywe ngamathangi okukhonkolo kanti amanzi ashintshwa ngamanzi 'amasha' nsuku zonke ukuze alondoloze ikhwalithi yamanzi.

Ezimweni ezifudumele, njengaseYurophu naseNingizimu Afrika, izinhlanzi zigcinwa ngaphakathi endlini yomshini wokushisa noma indawo yokugcina, futhi izinga lokushisa ligcinwe ngamapompi noma ukupheka kwamandla okushisa kagesi. Amanzi agodluzwa ngokuqhubekayo phakathi kwamathangi abo kanye nezihlungi ezinamandla ze-biological ukususa nokuguqula izidakamizwa zamanzi ezinhlanzi zibe yizifomu ezinobungozi. Lezi zinhlelo zokuvuselela amanzi ezihlelwe kahle (RAS) zikwazi ukukhiqiza ithani elilodwa lezinhlanzi ngamamitha angu-30 ngenyanga!

Ukusetshenziswa kwamachibi amanzi aluhlaza akufanelekile ukulima kwe-catfish eNingizimu Afrika njengoba isimo sezulu sibanda kakhulu ekukhuleni okuhle kulo nyaka. Noma yikuphi indawo lapho kungenziwa khona indawo yokushisa yokushisa kungadala ukukhiqizwa kwe-catfish.
Ukulawula ukushisa, ikhwalithi yamanzi omuhle, ukudla okuhle kakhulu nokuphathwa kahle yizo zonke izinto ezibalulekile zokulima kwe-catfish. Kubalulekile futhi ukuqaphela ukuthi ukutholakala kwamandla okuqhubekayo kuyadingeka njengoba i-catfish ayikwazi ukulima ngokuphumelelayo ngaphandle uma amandla ekhona.

Izigaba Zokukhula kwe-Catfish

Naphezu kokuba yinhlanzi enkulu yokulima, i-catfish iyamangalisa emangceleni.
Ukuphila ekuthunjweni kuqala ku-hatchery lapho abantu abadala be-catfish basebenziselwa khona ukukhiqiza amaqanda kanye nesidoda. Lawa ke ahlanganiswe nomphathi we-hatchery futhi abekwe amathangi ukuze ahlasele.
Amaqanda ama-catfish azwela ukukhanya, amathangi ahlanganiswe ngendwangu yomthunzi noma amashidi eplastiki amnyama ukugcina amaqanda kanye gazinga, izinhlanzi zezingane, ekukhanyeni.

I-fishfish yenza konke okusheshayo futhi i-hatching ayikho into; amaqanda azophanga amahora angu-24 ngemuva kokuzala. I-Fry isebenzisa izikhwama ze-yolk zazo cishe amahora angu-48 ngaphambi kokuqala ukondla ngaphandle okokuqala. Kuleli qophelo, i-Fry izokondla inhlanganisela yemifino yemvelo nokufakelwa, okuholela ekukhuleni okusheshayo.
Ngoba izinhlanzi ziyizidakamizwa zidinga ukuhlelwa masonto onke ukuqinisekisa ukuthi ithangi ngalinye liqukethe izinhlanzi ezilinganayo, ngaphandle kwalokho izinhlanzi ezinkulu zizodla izingane zakubo ezincane.

Ukukhula okuthunjiwe kuyashesha nge-catfish okufinyelela ku-1 kg ezinyangeni eziyisithupha ngemuva kokuqothula kanye no-2 kg eneminyaka eyi-8. Ukuze uphethile lokhu kukhula okusheshayo badliwa ukudla okuphezulu. Leli phepha libukeka njengezinja zezinja futhi liqukethe isobho, ummbila, ukolweni, ukudla kwesilwane (igazi, amathambo, izinkukhu, njll) kanye ne-premium ye-vitamin-mineral. Ngeshwa, kunezimboni ezimbili kuphela eNingizimu Afrika ezenza ukondliwa kwezinhlanzi kanye nezindleko zokudla zingabiza, okwakhiwa kuzungeze izindleko zokukhulisa izamba ezimbili / ezintathu.

Ukukhangiswa kwe-Catfish

Ngisho noma isigaba sokuqothula singenselele, isisindo esikhulu kakhulu somlimi we-catfish ukuwela i-marketing ngokuphumelelayo kwezinhlanzi uma befinyelela ukuvuna. E-RAS ungavuna nsuku zonke, masonto onke noma ngenyanga uma ukukhiqiza kuqhubeka. Inhlanzi ijwayele ukudayiswa ngo-1 kg, igcwala kuphela. I-catfish ingahle ifakwe ezimakethe ze-niche kodwa ibhekwa njengebiza kakhulu ezimakethe jikelele.

Ngaphakathi kwe-Afrika YaseNingizimu Afrika, inyama enhle, enhle kakhulu ye-catfish ayikakutholi ukuthandwa. E-Afrika Ephakathi naseNtshonalanga, lezi zinhlobo zithandwa kakhulu ngamathani angaphezu kuka-250 000 ehlanzwa minyaka yonke eCameroon, eNigeria naseDemocratic Republic of the Congo.
Yikuphi okubonakala kubonakala eNingizimu Afrika, noma kunjalo, imikhiqizo ye-catfish ebizwa ngokuthi yi-value-added njenge-sausages, pâté kanye ne-patties kanye nezibhamu zokudoba. Kulindeleke ukuthi, njengoba abathengi beqaphela izinzuzo zezempilo kanye nezoculinary zokudla i-catfish, isidingo salolu hlobo luzokhula endaweni yangakini.
