I-aquarium fish gambusia enhle kakhulu yazitholela endaweni yaseSoviet ngo-1925, lapho isuka e-Italy iya eSukhumi ukulwa nezinyosi ze-malaria. Iqiniso liwukuthi i-gambusia yezinhlanzi idla inqwaba yamapulangwe nezimpungushe zamanyane, ezihlanganisa ukuma ezincane ezinamanzi amakhulu.
Kwamanye amazwe, lezi zinhlanzi zibizwa ngokukhethekile ukulwa nokushaywa imilaria, okuyizinambuzane ezihluphekayo. Ngenxa yalokhu, amashumi eminyaka adlule, i-gambusia yayiqhutshwa emhlabeni jikelele. I-International Red Cross ngo-1920, i-batch of gambusia yacelwa ukuba i-Italy neSpain ibe yinkimbinkimbi. Ngokushesha kakhulu, lezi zinhlanzi zanda ngokugcwalisa amachibi aqhubekayo. Kwaphela iminyaka eminingana e-Italy, kwakungenzeka ukunciphisa i-malaria kumacala angashadile. I-Hambussia yahamba emhlabeni, ihlela amanzi asePalestine, iziqhingi zaseHawaii nasePhilippines, e-Argentina, eCaucasus, e-Asia Ephakathi nase-Ukraine.
Ngandlela-thile, i-gambusia, eye yabonisa ukuthi iyilwa elimangalisayo lokulwa ne-malaria, eCorsica nase-Adler, isikhumbuzo sakhiwe. Futhi ezinye izilwane zasemanzini ezihamba phambili zikhulula lezi zinhlanzi ezindaweni eziseduze zemvelo, ukuze i-squeak umiyane ingacasuli izakhamuzi zesifunda esiseduze ebusuku.
Ukugcinwa nokunakekelwa
Uma i-aquarium ivele kuwe kungekudala, futhi isipiliyoni asanele, khona-ke imisipha evamile iyinhlanzi eyokulandela. Lezi zinhlanzi azizithobeki, zizwe kahle emanzini amanzi anomswakama noma amasha, izinga lokushisa elingashintsha ngokubanzi (12-32 degrees). Uma izinga lokushisa liwela ezindigrikini ezingu-10, i-gambusia izocwilisa odakeni noma iwele phansi. Azikho izidingo eziqinile zokungcola kwamanzi noma okuqukethwe oksijini kulo. Ukunakekela i-gammon kulula kangangokuba ngisho nokuyondla akulula. Ngaphandle kokudla okomile okujwayelekile, inhlanzi inganikezwa izibungu ezimiyane ezivela emgodini oseduze kuya endlini.
Ukutshala ngokuvame ukuvame ukuvela ehlobo ngehora lokushisa kwamanzi ama-degrees angu-18 kuya ku-22. Phakathi nenkathi, i-gambusia yesifazane ingakwazi ukukhiqiza amalitha amahlanu gazinga. Ngendlela, umiyane ubhekisela ezinhlanzi eziphilayo. Izilwane ezincane kumele zibekelwe eceleni ngokushesha, ngoba ukudla komdlavuza akuyona indawo kubantu abadala. Abazali bayakujabulela ukuqeda amafry. Izinyanga ezimbili emva kokuzalwa, i-Fry isivele ivuthiwe ngokocansi.
Lesi silvery esiphezulu esinamahlumela aluhlaza okwesibhakabhaka asikwazi ukugcinwa emanzini ajwayelekile aqukethe omakhelwane abahlala phansi. Ngesikhathi esifushane, zonke izinhlawulo zizonqunyulwa yiGumbus, ngoba lezi zidalwa ezibonakala zihle kakhulu empeleni zinonya kakhulu.
