Jellyfish yemvura yakachena inochengetwa muaquarium

Mhando dzakawanda dzejellyfish dzinogara mumakungwa nemakungwa, asi kune imwe mhando yakabudirira kugadzirisa mvura yakachena - Craspedacusta sowerbyi. Mhando iyi inosiyaniswa nehukuru hwayo hudiki uye classic domed chimiro. Kuchengeta mu aquarium yemumba zvinogoneka, asi zvinoda mamwe mamiriro uye kuwanikwa kwechikafu chinogara chiripo.

Habitat

Freshwater jellyfish Craspedacusta sowerbyi yakapararira munenge makondinendi ese kunze kweAntarctica, inogara mumadhamu akadzikama uye rwizi rwuri kuyerera zvishoma nezvishoma, pamwe nemadziva ekugadzira uye madhamu.

Kutenga, kupi kutenga?

Dambudziko guru riri mukutora uye kutakura kwejellyfish yakakura. Paunenge uchibvunza muinjini yekutsvaga (zvisinei neYandex kana Google), maforamu akati wandei anowanikwa nekukurumidza apo vane ruzivo rwemvura vanogovana nyaya dzebudiriro mukupfuya nekuchengeta jellyfish, uye vanogona kukuudza kwekuitenga. Zvinofanira kuonekwa kuti mumaguta makuru makuru uye maguta akaita seMoscow neSt.

Kuchengeta mu aquarium (kurudziro huru)

Kubudirira kuchengetedza kunogoneka kana uchidzokorora mamiriro ekugara akafanana nemamiriro ekunze. Iwe uchada tangi diki rine huwandu hunosvika 40 litres yepeya yejellyfish. Mvura zviri pakati nepakati yakaoma kana yakapfava, pH isina kwayakarerekera. Verenga zvakawanda nezve pH uye dH paramita uye nzira dzekuzvishandura muHydrochemical kuumbwa kwechikamu chemvura. Iyo filtration system inokosha, inofanira kusanganisa kushanda kwepamusoro uye panguva imwechete kwete kugadzira kufamba kwemvura - jellyfish haigoni kupikisa kuyerera. Pamusoro pezvo, vanogona kusvetwa netsaona musefa. Mhedzisiro yakanakisa inoratidzwa nesefa yepasi, umo nzvimbo yesefa zvinhu yakaenzana nenzvimbo yevhu, inova nechokwadi chekutenderera kwemvura kwakaringana uye panguva imwechete inozadza neokisijeni.

Mimwe midziyo yakakosha inosanganisira heater, hurongwa hwekuvhenekesa hunogadziriswa kune zvinodiwa nezvirimwa (mumvuri-une rudo kana chiedza-rudo). Aerator inodiwa, kunyangwe uchishandisa sefa yepasi.

Mukugadzirwa kwezvishoma zvezvinhu. Ivhu rematombo madiki kana epakati ane mipendero yakatsetseka kana girazi rekushongedza. Zvirimwa kune kuravira kwako, zvinofanirwa kuganhurwa kune rimwe kana maviri makwenzi, usatendera iyo aquarium kukura, zvikasadaro hapazove nenzvimbo yejellyfish yekushambira.

chikafu

Yese jellyfish, kusanganisira yemvura yakachena, imhuka dzinodya. Nekubatsirwa kwematende uye masero anoruma ari paari, jellyfish inovhima mhuka dzayo. Muchiitiko ichi, ndiyo zooplankton: brine shrimp, daphnia, copepods (cyclops). Ivo vanofanirwa kuwedzerwa zuva nezuva mune zvidiki zvidiki kune aquarium. Iri idambudziko hombe kune mazhinji aquarist, havasi vese vanozokwanisa kupa isina kukanganiswa kupihwa kweaya crustaceans.

Kubereka

Hupenyu hwejellyfish hunoenda nematanho akati wandei. Craspedacusta sowerbyi kazhinji inobereka sexually. Munhu mukuru anobudisa mhute - planula (Planula), iyo muchimiro chayo uye hukuru hwakafanana neshangu yeciliate. Iyo planula inogara pasi uye inonamatira pamatombo kana zvirimwa zvemumvura. Gare gare, polyp inoumbwa kubva mairi, inokwanisa kukura kuva koloni huru. Nhanho yehupenyu muchimiro chepolyp yakasimba kwazvo, inokwanisa kuchinjika kune dzakasiyana siyana tembiricha, uye mumamiriro ezvinhu akashata (semuenzaniso, kusvika kwechando munzvimbo dzakadzikama) inoumba podocyte (podocysts) - a rudzi rwekudzivirira capsule, yakafanana muchinangwa kune cyst muma microorganisms.

Munhu mukuru anoonekwa chete mumamiriro ezvakatipoteredza anogamuchirwa kwairi uye pane tembiricha yemvura inopfuura 25 degrees; pasi pemamwe mamiriro, jellyfish inogona kupedza mwaka yakawanda iri muchimiro chepolyp. Ichi ndicho chimiro chinotsanangura kuwedzera kusingatarisirwi muhuwandu hwemvura yakachena jellyfish mune chero ipi zvayo yemvura, kana kunyange kuonekwa kwavo uko jellyfish isati yamboonekwa. Nokudaro, munguva yezhizha rinopisa muRussia muna 2010, Craspedacusta sowerbyi yakawanikwa muMoskva River.

Pamba, zvinokwanisika kuita kutenderera kwese kwekubereka jellyfish yemvura yakachena kubva papolyp kusvika kumunhu mukuru, dambudziko guru mukupa chikafu chipenyu. Kana jellyfish yakakura ichivhima yega, ipapo polyp, inoramba iri panzvimbo imwe, inogumira mune izvi zvingave, izvo zvinoreva kuti kusangana kwedaphnia, brine shrimp, uye copepods kunofanira kunge kwakakura kuitira kuti igone kubudirira kudya nekukura.
