Intakumba Water: inkcazelo lweentlobo, indawo yokuhlala, imikhwa lokondla kunye namanqaku anika umdla

INGCACISO crustacean Daphnia wafumana amanzi igama intakumba elidume sesibini Ukufana yakhe izinambuzane, kwaye ukukwazi ukuhamba ngokukhawuleza. Kodwa ngaphandle koko, babe nto eqhelekileyo, oko kukuthi. To. Ngaba abameli kwiiklasi ezahlukeneyo ngokupheleleyo.

Iimpawu ze isakhiwo sangaphandle

Daphnia - ilungu idumileyo lentsapho nesinabantu Daphniidae. Kwesikhumba le ephilayo bicuspid, namagwegwe ababini kwelinye icala lomzimba iliso eshukumayo sphericity, leyo iqhutywa izibini ezintathu izihlunu oculomotor. umzimba Daphnia sikhanya kwaye ikuvumela ukuba ubone yonke into eyenzekayo emzimbeni wakhe. Nditsho ukuncipha incinane izihlunu crustacean ungabona kwi neemicroscope uma oyifunayo.

Iimpawu yesakhelo sangaphakathi

Nangona ubukhulu bayo isinciphiso, umzimba kuyinto eyoyikekayo intakumba amanzi. Inkcazelo lohlobo iqaphele inani lemisebenzi esemqoka umdla kubume yayo yangaphakathi. Izintso Daphnia zikufutshane emlonyeni, ubuchopho - kufutshane kuvuleke iminxunya nentliziyo - phezu ngasemva umntla. Igazi bulubhelu siqulathe iiseli ezimhlophe - ziiphagocytes, ekhusela umzimba xa kuyimfuneko crustacean yibhaktheriya, umngundo kunye eziphilayo amazwe.

intakumba Amanzi izibini ezintlanu imilenze, kodwa hayi kakhulu ngenxa intshukumo, kodwa zokwalathisa ukuphuma kwamanzi emlonyeni wakhe, leyo yena lihluzwe ubukho kwezondlo. Uphefumla ngqo ngawo umzimba ezikuyo.

iimeko Distribution nokuphila

Daphnia kugcwele phantse kulo lonke jikelele. Abaninzi kubo sub-ndawo kunye kwisibanzi ziingcathu. Ngokusisiseko, intakumba amanzi ehlala emanzini amileyo (amachibi, amachibi, imilambo kunye kwemali kade), kwakunye kumadama. Iphindaphindeka ngokukhawuleza, enamandla kakhulu, ngoko inani yakhe inkulu kakhulu. Ngaba ngokuqhelekileyo kwikholam emanzini, igaqa okanye siphinda- esihamba emazantsi (ngenxa imilenze thoracic).

Daphnia ihlobo ukuqubha fast, kodwa xa amaxesha ezimbi - ngumkhenkce. Nokuba echibini apho afumaneka khona, owomileyo, ngoko ke kubuyela ebomini ngokukhawuleza njengoko igcwele kwakhona.

daphnia kakhulu - ngu herbivorous, kodwa kukwakho ngamarhamncwa. intakumba Water benzise ziiphytoplankton, umngundo, iintsholongwane kunye ebangele iintsalela esiqwini izilwanyana emva kokusebenzisa amarhamncwa yayo enkulu.

Yeyona ixhaphakileyo iintlobo

Daphnia intsapho ezininzi kakhulu. Kuphela eYurophu nakuMntla Melika lilikhaya malunga 150 iintlobo kwezilwanyana. ERashiya, kuyinto ixhaphake, abanye babo - magna, puleks, kukulata, Galeata, Crest. Bonke bahlala amanzi ezahlukeneyo.

Izenze wamanzi - Daphnia magna. Ibhinqa isiphathele ubude 6 mm, inkunzi izihlandlo ezithathu ngaphantsi. ixesha ekukhuleni le Daphnia usana ithatha iiveki ezimbini. Imazi izala amaqanda ayo kwakhona emva kweeveki ezimbini (amaqanda malunga ezintathu elinesibini). Okokuqala, abantwana aba obungabonakaliyo ngobukhulu. Kodwa ke ikhula ngamandla. Ukuphila olu hlobo iinyanga ezintathu.

Olunye uhlobo oqhelekileyo - into puleks Daphnia. Abameli kuye kancinci ezincinane - malunga ezine eemilimitha iimazi, amaduna ngokuphindwe kabini ngaphantsi. Bona kwande kakhulu - iyabala ngaphandle amaqanda elinesihlanu kwenzeka kanye yonke ezintlanu. Ukuphila ezi iintakumba amanzi elide - umjikelo wobomi ungaba kuze iinyanga enye enesiqingatha. Kuyahluka ngokuxhomekeke kwiimeko zentlalo. Umzekelo, ukunyuka kwamaqondo obushushu kunciphisa ubomi ngenxa yokuba kukhulisa ukutya of kwezilwanyana.

buphindwe

iintakumba Water beba kakhulu. Zonke iqanda-ngokubekwa daphnia yahlulahlulwe ihlobo nobusika. Amaqanda kwixesha elithile babe neempawu zabo. Umzekelo, ebusika wamatye, ziza kukhutshwa kunye iqokobhe exineneyo inani labo lincinane (2 iiyunithi), kwaye ehlotyeni zininzi kakhulu. Zonke ezi mpawu ngenxa amaxesha amade kunye neemeko zokuphila, kwaye ubukho into eyindoda. Ehlotyeni, xa abemi amadoda liphantsi kakhulu, kuvela amaqanda Daphnia kwaye zenziwa ngaphandle isichumiso. Amaqanda ivundiswe yi eyindoda, walibala kanye kuphela ngonyaka - ekwindla. Ngexesha yobomi yayo lomjikelo amaqanda kuzala amaxesha-25.

Daphnia umonakalo abantu

Ngaphandle kwento yokuba yintwala amanzi Daphnia kuthiwa, ubuhlobo ukulunywa oko akunanto yakwenza. Kunjalo ukulimaza abantu zingabangela. Yonke into allergenic kakhulu. Oku kubangelwa kukuba ebudeni izityalo lokudubula enogonyamelo, umungu ingena emanzini, nto leyo iqulathe Daphnia, kunye nabo ke profiltrovyvaya ukuba sifake amasuntswana kanye umungu. Ngoko, xa yomile ezineqokobhe, le umungu uhlala kwaye baxabane namachiza okanye nezidlo ezithile emzimbeni womntu, nto leyo edla ngokuphosakeleyo iintakumba zamanzi ezilumayo.

Iimpawu umzimba kaninzi eqhelekileyo - ukudumba conjunctiva lwalo (conjunctivitis), amehlo alilayo, rhoqo uthimla, ukuxinana ngeempumlo kunye ubunzima ukuphefumla.

Ngamanye amaxesha oko kuvela kwamaqhakuvana emzimbeni, kunye ukurhawuzelela kakhulu.

Ukusebenzisa Daphnia indoda

Ngenxa yoko, le iintakumba Kukudla jikelele kweentlanzi Aquarium. Ngenxa yoku, ukuba wakhulela kwikhaya.

Kuyimfuneko kuphela ukubamba Daphnia emanzini amileyo, kunye nokubanika neemeko zokuphila kufutshane zendalo. Ukuganga intlanzi eveza amadama apho luncinane okanye akukho intlanzi, njengoko kungekho ezidla Daphnia kakhulu yaye ngaphantsi kusenokwenzeka ukuba boyisiwe naluphi na usuleleko.

Imigaqo yokuzalela

iintakumba kwamanzi akwariyam kufuneka zigcinwe emanzini ahlala kuyo, kuba amanzi empompini na ukutya ukuba badle. Kufuneka kwakhona babe ingqalelo ukhetho zizinto ebekupakishwe apho intlanzi ziza kufumaneka. Enyanisweni, izinto ezifana umzekelo ezinepolypropylene, wadibana amanzi kukhupha izinto eziyingozi, kunye Daphnia ife.

Equlethwe iimeko akwariyam i uDaphne ufuna eninzi ukukhanya. Xa egumbini elikhanyayo, ikhula futhi sizale elungileyo. Ukongeza, intakumba ungenako ukubathwala ubuhlobo. Njengoko banda ngokukhawuleza, kufuneka rhoqo ukuqinisekisa ukuba zibe nesithuba esaneleyo yaye ngamaxesha athile udlulise iindawo iintakumba zamanzi komnye akwariyam. Oku kunokucaciswa yinto yokuba intlanzi ziyivela kakhulu yokunqongophala kwe-oksijini bafe ngokukhawuleza, uya kufumana ngaphantsi.

aquarists abaninzi zizala daphnia, bathi ukudla okulungileyo kubo - igwele umbhaki yakhe. ondle kuphela daphnia ukuba silumke - Xa ugalela ukutya kakhulu, amanzi turbid, ioksijini ezineqokobhe ziya kuba ngokwaneleyo. Xa akwariyam ngeelitha ezintlanu isixa ilungelo engenagwele, lingana ne ukuya ubungakanani intloko bomdlalo. Kufuneka kubenze itispuni amanzi ngokucotha uthululele zima. Kwakhona ukutya kwezilwanyana ezi ulwelwe eluhlaza, kuquka Euglena eluhlaza kunye Chlorella.

Kubalulekile ukuba uqaphele ukuba ubushushu kubo kufuneka ezithile. Oku, ngokutsho kwiingcali, ukusuka izidanga 22 ukuya 25. Kuyinto kwezi meko wabandisa iintakumba amanzi kwidama lomzimba yamanzi yendalo.

Kuyimfuneko ukukhusela Isiyaluyalu amanzi kwaye utshintshe amanzi (a yesithathu ngumthamo opheleleyo) angekho ngaphantsi kwesinye okanye kabini ngeveki.

Intlanzi Daphnia ekucingeni ngokugqibeleleyo amanzi yibhaktheriya. Ngoko ke, aquarists abaninzi zintombi kuwo amanzi - oku akuthethi okwentyatyambo nelide ihlale icocekile.

Ekuqaleni, kuye kubonakale ukuba daphnia ezizalayo ekhaya - lo ngumba onzima kakhulu, yinkqubo ethatha ixesha elide. Kunjalo, ezi ezineqokobhe - ngonyaka-ngeenxa zonke ukutya esingqongileyo ecocekileyo kuninzi iintlobo fish (njengoko isencinci kunye nabantu abadala).

amanzi Bloch umkhathalele kakhulu kungcoliseko kunye nokusingqongileyo utshintshe nokubunjwa kwayo ionic (isodiyam nemagnesium, calcium kwaye njalo njalo). Kungenxa yesi sizathu ukuba intlanzi badla zisetyenziswa ukugqiba umgangatho wamanzi (njengoko amanzi kunye namanzi ukusuka amadama ivuliwe).
