I-jellyfish yamanzi ahlanzekile igcinwe ku-aquarium

Iningi lezinhlobo ze-jellyfish zihlala olwandle nasolwandle, kodwa kukhona uhlobo olulodwa oluye lwajwayela ngempumelelo emanzini ahlanzekile - i-Craspedacusta sowerbyi. Lolu hlobo luhlukaniswa ngobukhulu balo obuncane kanye nokuma kwe-domed yakudala. Ukugcina ku-aquarium yasekhaya kungenzeka, kodwa kudinga izimo ezithile kanye nokutholakala njalo kokudla okuphilayo.

habitat

I-jellyfish yamanzi ahlanzekile i-Craspedacusta sowerbyi isabalele cishe kuwo wonke amazwekazi ngaphandle kwase-Antarctica, ihlala ezindaweni ezihlala emanzini amile kanye nasemifuleni egeleza kancane engemuva, kanye namachibi namachibi okwenziwa.

Thenga, ungathenga kuphi?

Ubunzima obukhulu busekuthengweni nasekuthuthweni kwe-jellyfish endala. Uma ubuza enjinini yokusesha (kungakhathaliseki ukuthi i-Yandex noma i-Google), izinkundla ezimbalwa ezikhethekile zitholakala ngokushesha lapho ama-aquarists anolwazi abelana ngezindaba zawo zempumelelo ekuzaleni nasekugcineni i-jellyfish, futhi angakutshela ukuthi ungayithenga kuphi. Kumele kuqashelwe ukuthi ezindaweni ezinkulu zamadolobha amakhulu namadolobha afana neMoscow neSt. Petersburg, kulula kakhulu ukuthola i-jellyfish yamanzi ahlanzekile, ngokungafani nezifunda.

Ukugcina ku-aquarium (izincomo ezijwayelekile)

Ukunakekelwa okuyimpumelelo kungenzeka lapho kwakhiwa kabusha izimo zezindawo zokuhlala ezifana nemvelo yemvelo. Uzodinga ithangi elincane elinomthamo wamalitha angaba ngu-40 ngepheya le-jellyfish. Amanzi angcono amaphakathi aqinile noma athambile, angathathi hlangothi nge-pH. Funda kabanzi mayelana namapharamitha e-pH ne-dH nezindlela zokuwashintsha esigabeni samanzi se-Hydrochemical. Uhlelo lokuhlunga luyisihluthulelo, kufanele luhlanganise ukusebenza okuphezulu futhi ngesikhathi esifanayo lungadali ukunyakaza kwamanzi - i-jellyfish ayikwazi ukumelana nokugeleza. Ngaphezu kwalokho, zingamuncwa ngephutha kusihlungi. Imiphumela emihle kakhulu iboniswa yisihlungi esingezansi, lapho indawo yesihlungi ilingana nendawo yenhlabathi, iqinisekisa ukuhamba okuqondile kwamanzi okuqondile futhi ngesikhathi esifanayo igcwalisa umoya-mpilo.

Eminye imishini ebalulekile iqukethe i-heater, uhlelo lokukhanyisa lulungiswa ngezidingo zezitshalo (umthunzi-othanda noma othanda ukukhanya). I-aerator iyathandeka, ngisho nalapho usebenzisa isihlungi esingaphansi.

Ekwakheni ubuncane bezakhi. Umhlabathi wamatshe amancane noma aphakathi nendawo anemiphetho ebushelelezi noma ubuhlalu bengilazi bokuhlobisa. Izitshalo ekunambithekeni kwakho, kufanele zikhawulelwe esihlahleni esisodwa noma ezimbili, ungavumeli i-aquarium ukuthi ikhule, ngaphandle kwalokho ngeke ibe khona indawo yokubhukuda i-jellyfish.

Ukudla

Zonke i-jellyfish, kuhlanganise namanzi ahlanzekile, ziyizilwane ezidla ezinye. Ngosizo lwamatende namaseli ahlabayo aphezu kwawo, i-jellyfish izingela inyamazane yayo. Kulokhu, kuba zooplankton: brine nezimfanzi, daphnia, copepods (cyclops). Kufanele zengezwe nsuku zonke ngamanani amancane ku-aquarium. Lena inkinga enkulu kuma-aquarists amaningi, akuwona wonke umuntu ozokwazi ukuhlinzeka ngokuhlinzekwa okungaphazanyiswa kwalawa ma-crustaceans.

Ukukhiqiza

Umjikelezo wempilo ye-jellyfish udlula ezigabeni ezimbalwa. I-Craspedacusta sowerbyi ivamise ukukhiqiza kabusha ngocansi. Umuntu omdala ukhiqiza isibungu - i-planula (i-Planula), esesimweni sayo nobukhulu obufana nesicathulo se-ciliate. I-planula izinza phansi futhi inamathele emadwaleni noma ezitshalweni zasemanzini. Kamuva, kwakheka i-polyp kuyo, ekwazi ukukhula ibe ikoloni elikhulu. Isigaba sempilo ngesimo se-polyp siqinile kakhulu, siyakwazi ukuzivumelanisa nezinga lokushisa elibanzi, futhi ezimweni ezimbi (isibonelo, ukufika kobusika ezindaweni ezipholile) sakha i-podocyte (podocysts) - a uhlobo lwe-capsule yokuzivikela, efana nenjongo ne-cyst kuma-microorganisms.

Umuntu omdala uvela kuphela ezimweni zemvelo ezamukelekayo kuwo futhi emazingeni okushisa amanzi angaphezu kwama-25 degrees; ngaphansi kwezinye izimo, i-jellyfish ingachitha izinkathi eziningi zonyaka ngesimo se-polyp. Yilesi sici esichaza ukwanda okungalindelekile kwenani le-jellyfish yamanzi ahlanzekile kunoma iyiphi ingxenye yamanzi, noma ngisho nokubukeka kwayo lapho i-jellyfish ingakaze ibonwe ngaphambili. Ngakho, phakathi nehlobo elishisa ngendlela engavamile eRussia ngo-2010, iCraspedacusta sowerbyi yatholakala eMfuleni iMoskva.

Ekhaya, kungenzeka ukwenza wonke umjikelezo wokuzalanisa i-jellyfish yamanzi ahlanzekile ukusuka ku-polyp kuya kumuntu omdala, ubunzima obukhulu ekunikezeni ukudla okuphilayo. Uma i-jellyfish endala izingela yodwa, khona-ke i-polyp, ehlala endaweni eyodwa, inqunyelwe kulawa mathuba, okusho ukuthi ukugxila kwe-daphnia, i-brine shrimp, nama-copepods kumele kube kukhudlwana ukuze akwazi ukondla ngempumelelo futhi akhule.
