Mvura yemvura: kuti daphnia inoratidzika sei uye kuti inokura sei
Daphnia icrustacean iri chikafu chehove dzemu aquarium. Vanoda kutarisirwa panguva uye kudya kwakakodzera. Daphnia parizvino iri kutengeswa. Kare, vanhu vazhinji vakavabata mudhamu rezvisikwa. Uyewo ma<em>crustaceans anonzi ma<em>water fleas.
Zviri mukati
Daphnia anotaridzika sei: mufananidzo
Tsanangudzo yezvipembenene
zita: Daphnia
Ratini: DaphniaKirasi: Zvipembenene - chipembenene
Chikwata: Gill-footed crustaceans - Anomopoda
 | Nzvimbo dzekugara: | dziva dzakamira |
 | Simba rekushandisa: | algae, plankton elements |
 | Kuparadza: | zvipembenene zvinova vanyajambwa vehove dzakasiyana |
Daphnia pasi pe microscope.
Iyo diki crustacean ndeye planktonic crustacean dzakasiyana. Kukura kunoenderana nerudzi. Inogona kusiyana kubva pa2 kusvika ku6 mm. Nekuda kwekukura kwemuviri, zvakaoma kuona chimiro. Maikorosikopu ichabatsira neizvi.
Muviri une ovha muchimiro. Pamativi ose maviri kune furemu yakakosha. Inomiririra kuchengetedzwa kwenhengo dzomukati. Nhengo dzekunhuhwidza idzonga dziri mumusoro. Nekubatsira kwavo, nhata dzinokwanisa kusundira kure, kushambira, kusvetuka.
Pane makumbo pachipfuva. Algae uye mabhakitiriya anopfuura mavari. Nhata dzinogona kufema nemasaga egill. Gill sacs ane bristles anoita sesefa.
Kune anopfuura zana nemakumi mashanu emhando dzecladoceans. Mune yedu latitude unogona kuona:
- magnu - mhando huru;
- pulexa - ine avhareji saizi;
- yangu - diki.
Kune nguva dzose kudya kwekudyara mudumbu. Iyo ine zvinhu zvinobatsira zvekutsvaga izvo zvinodikanwa nevagari veiyo aquarium.

Nzvimbo yekugara inogara madhamu asingayerere. Vanogona kugara zvose mudziva uye mumvura yakadzika. Kunyange Antarctica inotonhora haina kudaro.
Imwe yemamiriro ezvinhu makuru kuvepo kwemvura isingayerere ine ivhu shoma.
Mvura yepasi inobatsira mukusefa kwevhu uye kuti algae igare mumatumbu.
Daphnia: natural filter.
Izvi zvinotungamirira kukuvhara. Nekuvapo kwekrustaceans mumvura, zvinova pachena kuti dziva, dziva, rwizi rwakachena sei. Mvura yepasi inobatsira mukusefa kwevhu uye kuti algae igare mumatumbu. Izvi zvinotungamirira kukuvhara.
Mamwe marudzi anogara pasi, achidya zvikamu zvakafa zvezvokudya zvezvirimwa uye zvakasara zvezvipembenene. Dzimwe nguva vanogona kuonekwa mumapuddles nemakomba ane mvura. Muchiedza chakajeka, crustaceans inovanza zvakadzama. Zvipembenene izvi zvinowanzowanikwa mukati madziva nemadziva.
Daphnia kudya
Daphnia mumvura.
Chikafu chikuru chine mbiriso uye mabhakitiriya ebhuruu-girini. Mushonga mukuru we unicellular unogona kuwanikwa mumudziyo wemaruva, umo hove shoma dzinogara. Vanodyawo ciliates uye detritus.
Kusefa kwemvura kunoitika nekuda kwemakumbo epectoral. Mushure meizvi, chikafu chinopinda mugomba redumbu remudumbu, uye ipapo mune esophagus. Iyo salivary gland uye kuvharika kwemiromo yekumusoro kunobatsira kunama kwezvikamu zvekudya kuita bundu.
The filtration rate yevanhu vakuru inobva 1 kusvika 10 ml mukati mezuva. Kurema kwemuviri kunokanganisa huwandu hwekudya. Munhu mukuru magna anokwanisa kudya 600% yehuremu hwemuviri wayo.
Kutenderera kwehupenyu
Kugona kubereka hakudi kuti urume. Madzimai ane kamuri yevana. Inodzivirirwa nemucheto wegoko. Mamiriro ezvinhu akanaka anofarira kukandira mazai makumi mashanu kusvika ku50 asina kubereka. Mumakomba, kukura kwevakadzi kunoitika. Zvadaro, hadzi dzinobuda mumhango.
Muvakadzi, molting inotanga. Mazuva mashomanana gare gare, nzira yekubereka inodzokororwa nerubatsiro rwevanhu vakuru. Mukadzi mumwe chete anogona kuita vana vanosvika makumi maviri nevashanu muhupenyu hwake. Nokuda kweizvi, ruvara rwechidziva runova rutsvuku.
Mumatsutso, varume vanotanga kutora chikamu mukuita. Goko rakaiswa fetiraiza rakakora kwazvo. Inokwanisa kutsungirira chando chakanyanya uye kuoma kwemitumbi yemvura.
Nekutanga kwechirimo, kubereka kunodzokororwa nekuda kwevakadzi. Vanhu vatsva vane chimiro chemuviri chakasiyana. Nguva yehupenyu hwedaphnia yakakura ndeye 4 kusvika kumwedzi mishanu. Vamwe vamiririri vanogona kusvika mavhiki matatu.
vavengi venyama
Vavengi ndivo vanodya mhuka duku. Vavengi venyama vanosanganisira:
- hove duku;
- fry;
- hozhwa;
- matatya;
- newt larvae;
- vamwe vagari vemo.
Mamiriro ekurera
Iwe unogona kubereka daphnia kumba. Mazano mashoma:
- mvura inofanira kuva neruvara rwakasvibira kana rwakajeka;
- vamwe vamiriri vedhamu havabvumidzwe kupinda. Somuenzaniso, Cyclopes;
- kudya kukuru kunofanira kuva lettuce yakaoma kana mazambiringa;
- dyisa mbiriso yemubiki, iyo inofanopwanyika uye inonatswa kuburikidza ne gauze;
- zvakakwana kuchera mvura kubva mudziva umo mune vanhu makumi mashanu. Zvokudya zvakabikwa zvinowedzerwa kumvura iyi;
- shandisa chigadziko chegirazi, asi chiise kure nechiedza chezuva;
- kunamatira kune tembiricha kubva pa20 kusvika ku24 degrees Celsius;
- chenesa uye shandura mvura kudzivirira kuunganidzwa kwemarara kana silt pasi;
- shandisa mvura isina chlorine uye kusvibiswa kwemakemikari.
Zvakanakira Daphnia
Daphnia ine mapuroteni akawanda. Amino acids inokurudzira kukura nekukurumidza. Kazhinji kazhinji ivo vanowedzerwa kune yakaoma hove chikafu. Muchiitiko ichi, hafu yehuwandu mapuroteni.
mhedziso
Daphnia chikafu chakakosha chehove ye aquarium, inotengeswa muzvitoro. Kutenda kuhupenyu hwekudya, hurwere hunoderedzwa uye kuchinjika kumamiriro matsva zviri nyore. Zvisinei, kana uchida, unogona kuzviberekesa iwe pachako.
