Daphnia: yemvelo. Apho uhlala iintakumba? Ngaba kunokwenzeka ukuba daphnia ezizalayo ekhaya?

Abaninzi bethu bonwabile ukubukela intshukumo abathathela wentlanzi kwi-akwariyam. Le mbono luthoba kwaye buyasikhulula isingxobo, kodwa bambalwa okunene ndiyazi iphume kanjani inkinga ukulungisa lwendlu ubuhle enjalo.

ukudla fish

Sele abaninzi abathandi yentlanzi engamashumi yezilwanyana sebenzisa Daphnia nezokudliwa izilwanyana zakho zasemanzini. Nakumaxesha Soviet, ezi kwezilwanyana wambamba aquarists imizimba zendalo zamanzi. Iyaqondakala ukuba kufuneka wazi kanye ubomi apho Daphnia. Emva koko ukubamba intlanzi kusetyenziselwa kuphela ngendlela eziphilayo, kodwa emkhenkceni, kwaye zonekwe. Kakade ke, ekhaya kukho inani elikhulu kubo kakhulu nzima, nto leyo esisizathu sokuba abantu abaninzi bazama ngumkhenkce le Daphnia kwixesha lweenkomo abaninzi endle. Ukuba sithethe malunga nexabiso lesondlo sokutya kungahlala, oko phantse engabumbeki i kwezilwanyana ngqo. Okwangoku ezivenkileni yezilwanyana, ungakwazi ngokulula ukuthenga daphnia engumkhenkce, ngoko kukho workpiece elizimeleyo onjalo uba amazwi yexesha elidlulileyo.

Ubume daphnia

Ndingathanda ukuthetha kancinci indlela yokwakha ezi cladocerans, kuwo nesiwubiza ngokuba daphnia. umzimba wazo womelele ngokwaneleyo yokuxazulula zixinaniswe, azigubungela yokugqibela enezigaba ezibini ngechitin iqokobhe.

Daphnia ngokuqhelekileyo unamehlo amabini, nto leyo zicwangciswe entloko, kodwa ngamanye amaxesha abaqolileyo abantu abafani bubukho compound iliso, kufuphi apho yomnyango ezincinane eyongezelelweyo inokuba. Xa intloko ubungakanani obuncinane nayo ngambini kuzo eriyali. Ngasemva (okwesibini) unikwa nge pair ngakumbi ezifumaneka kwaye ubukhulu enkulu. Kuyinto ngenxa kwezi stroke antennok ngoxa uqhuba daphnia ukwenza uhlobo iintlantsi. Ngoko ke, abantu kuthiwa "iintakumba yamanzi".

kwezilwanyana yokuzala

Ukuba ujonga inkqubo yokuzala ezi intlanzi amancinci kwindawo ngokwenyama, ngoko udlula engaqhelekanga kakhulu. Iimazi yalo zezinto eziphilayo ekuthiwa amantshontsho yakutya olukhuselwa edge iqokobhe kwaye zilahlwa ngasemva. Xa iimeko zivuma zenzelwe ehlabathini izala 50-100 amaqanda unfertilized kungena lweHo-, apho ukuphuhlisa. Kubalulekile ukwazi ukuba la amaqanda iimazi kuphela wabonisa ngokukhuselekileyo ushiye egumbini. Kwiintsuku ezimbalwa le nkqubo iphindiwe, nemazi entsha, wakhula, kuvuthwa nokurhuma kule nkqubo ukuzala ngokukhawuleza. Kungenxa yoko le nto ehlotyeni ohlala apho daphnia, amanzi ngokungathi zipeyintwe ngombala obomvu. Ichibi into enyakazelayo nayo kwizidalwa. Xa kuphela ihlobo, ubushushu uvikivwa namanzi, kukho amadoda abo umgquba iimazi iibhola kunye nesikhumba ashinyeneyo. La maqanda ivundiswe ibizwa ngokuba Ephippia. osemqoka lwabo lokwahlula kukwazi ukumelana kuneqabaka zasebusika namachibi eyomileyo, kwaye isasazeka uthuli. Nokufika entwasahlobo, nobushushu kwezi iimazi amaqanda, umjikelo wobomi kuphinda kwakhona.

yokuhlala

Emva kokuba safumanisa oko daphnia, ezi amalungu sodidi lwe yokuhlala planktonic kufuneka kwaziwa kuthi, njengoko ndiqinisekile abaninzi kwabo ukufunda eli nqaku kukho amateurs intlanzi yezilwanyana, ndinqwenela ukuba olunjalo ulwazi. Ngoko ke, ukuba ukuhlangana ezi intlanzi encinci iyakwazi ukuba imizimba amanzi amileyo ezifana amachibi, amachibi, namaqula ngamanzi, izisele nkqu izadunge. Amaxesha amaninzi for self-ukuvuna daphnia ziindawo kakhulu nawo abaninzi. Chonga indawo ungakwazi lula ngokwaneleyo: apho daphnia live, amanzi kudla Tint engwevu-eziluhlaza okanye bubomvu. Food for kwabo ciliates, iintsholongwane, izityalo nezilwanyana.

La Daphnia ezahlukeneyo

Abo banqwenela ukuba ukubamba Daphnia zabo kufuneka ingqalelo, njengoko iso ukukhanya. Xa ukukhanya okuqaqambileyo, ezineqokobhe uya kuzama ukuya nzulu. Kukho iindidi ezahlukeneyo Daphnia. Eyona amaninzi zifumaneka kwindawo phakathi Daphnia magna crustacean. Imazi ufikelela ubude 6 mm, kwaye apha inkwenkwe - mm 2 kuphela. Zihlala ngokuqhelekileyo iintsuku 110-150, kwaye azise bamba amaqanda ukuya ku-80, nto leyo ikhule iintsuku 4-14. I intlanzi zincinane ukufikelela mm 1.5 kuphela ubungakanani kwaye ivuthwe emini, kodwa nasemathaleni zonke iintsuku 1-2 ukuya amaqanda 53.

Yintoni na elungileyo iintlanzi?

Kwakutheni ukuze abathandi intlanzi akwariyam bazama ukuba uqiniseke ukubondla daphnia? Yinto elula kakhulu. Nokuba yokuba enoba lumiswa okanye intlanzi ubanjwe esanda, isisu sabo idla ngokupheleleyo ukutya sesityalo, kodwa ke kunjalo kulungile akwariyam intlanzi, abo ndayihluthwa yemvelo yokudla. Yiloo Oko kumele kutheni babe iintakumba kwi-akwariyam. Ngaphandle kwento yokuba iqokobhe Daphnia ayenziwanga ukudla, ukuba ukhonza obalaseleyo ifayibha zokutya. Enkosi kuye, kukho ekuhlaziyeni emathunjini iintlanzi, leyo akakwazi ukuhambisa ngokupheleleyo akwariyam. fish Kuba azikakhuli akwariyam yi abameli nje olucokisekileyo daphnia lincinci - Ministry of Education, bafumana eyaziwa ngokuba "viviparus".

Ukuba uceba ngokwabo ukubamba intlanzi, kufuneka sikhumbule ukuba apho uhlala daphnia, kwenzeka nangendlela ecwangciswe kakuhle ngokulandelelana ukutshintsha ubungakanani yabemi kwezilwanyana. Kuba ukuloba inyama net lasebenzisa ogama iiseli kufuneka ukungqinelana catch oyifunayo. Abanye "abalobi" abanamava bacetyiswa ukuba ukubamba umnatha ibhabhathane kunye enemingxuma entle kakhulu, kwaye ke kuphela ukuyisombulula le ukutya ngobukhulu ngokusebenzisa screen kunye enemingxuma ezahlukeneyo. Ukuzibandakanya ekulobeni kangangoko kunokwenzeka, ukuqalela entwasahlobo de dama ubonakala uqweqwe lomkhenkce. Sakhetha umcimbi onjalo lidla ikhuselwe ukusuka elunxwemeni umoya ngosuku ezolileyo ekuseni okanye ngorhatya. Ngokusesikweni, ukuba izibane libunile. Ke daphnia, indawo yokuhlala apho ngoku kubonakala kakuhle, ivuke umphantsi nomphezulu.

Tips banamava

Khumbula ukuba yenamvuna akubanyamezeli ezixineneyo kakhulu, ngoko ke ukuthuthwa daphnia emva ukubamba kukuqonda oko. Kwakhona zizakulahleka ukuba utshintsho ngokukhawuleza lobushushu. Oku kubhekisela inkqubo yokuhlela kunye nokuhlamba, kwakunye yokondla iintlanzi. Kubalulekile ukuqaphela abanini akwariyam ukondla izilwanyana zabo ezingahlanjwanga kwezilwanyana eziyingozi. Oku kungakhokelela ekubeni ufundisa kweekhowudi izinambuzane okanye wosulelo kwichibi yakho yasekhaya.

zikhwelwe daphnia

Ezihlala apha iintakumba ekhaya - ingqesho ngokufanelekileyo elula, kodwa ufuna ukukhathalelwa kunye nomonde. Oku ngesiqhelo isetyenziswe ukutya, igwele yombhaki. Kufuneka uqonde ukuba umbala amanzi kwi isitya apho ukuzalela kwezilwanyana. Amanzi kufuneka ibe ezibuhlazarha, okanye ukukhanya omdaka. Ukuba uphawula ukuba umbala luthe ifumile, ngoko imfuneko ukumisa iintsuku 1-2 ngokwenza nagwele. ngokukhawuleza kakhulu, amanzi kufuneka ubenze kwakhona.

Ukuba lwemfuyo Daphnia kubonakala kuwe yinto nje yokuzonwabisa mnandi kakhulu umdla, ulumke kakhulu kwaye uqinisekise ukuba kunye intlanzi ukuya isitya zange ndifumane ezinye abemi amadama, ingakumbi cyclops. Fumana iglasi nokuhlola zonke iimazi imihla egumbini ukuzingcungcuthekisa. Ukuba eliphantsi amaqanda, kuyimfuneko ukuqinisa isondlo. Daphnia, ezihlala ekhaya - i akwariyam okanye umgqomo wamanzi okwethutyana, nako zatya womile amagqabi umba okanye lettuce. Ngaphambili ke acolwa, uze emva koko kuhluzeka cheesecloth.

Kukho nenye indlela elula daphnia ezizalayo ekhaya. Ukuze wenze oku kwiiklasi onzima kuya kufuneka yeplastiki okanye lwawo ibhafu, ekufuneka isiqingatha sifunxe amanzi, yaye yalala anokungenwa hay kunye namagqabi bawa. Ngaphezu koko, kule ubunzima iintsholongwane ziza kuphuhlisa, nto leyo eya kuba kukudla kwezilwanyana. Ngamanye amaxesha, ukwenzela ukunika amandla eyongezelelweyo iintsholongwane, amanzi zafakwa kwi intwana elincinane Igwele (malunga ne-15 g nganye-1 m ³ yamanzi). Oku kufuneka kwenziwe rhoqo kwiiveki ezimbini njengoko amanzi iba lighter.

Kwaye ngoku ke ibaluleke kakhulu into: daphnia, yokuhlala - ngokuqhelekileyo oku umzimba ongowemvelo amanzi kufuneka kungena isikhongozeli yakho ukutya okuphekiweyo. Ukulungiselela le njongo kwi bemi catch ichibi malunga nama-100 eelitha zamanzi 50 intlanzi kunye agalelwa isikhongozeli uzilungiselele.
