Izeze zamanzi: ukuthi i-daphnia ibukeka kanjani nokuthi ikhula kanjani
I-Daphnia iyi-crustacean ewukudla kwezinhlanzi zase-aquarium. Badinga ukunakekelwa ngesikhathi kanye nokudla okufanele. I-Daphnia iyathengiswa okwamanje. Ngaphambili, abantu abaningi bababamba endaweni yokugcina amanzi. Futhi ama-crustaceans abizwa ngokuthi amazeze amanzi.
Okuqukethwe
Indlela uDaphnia abukeka ngayo: isithombe
Incazelo yalesi sinambuzane
Igama: I-Daphnia
Isi-Latin: UDaphniaIbanga: Izinambuzane - isinambuzane
Isigcawu: I-Gill-footed crustaceans - i-Anomopoda
 | Izindawo zokuhlala: | amanzi amile |
 | Ukunikezwa kwamandla: | ulwelwe, izakhi ze-plankton |
 | Ukubhujiswa: | izinambuzane ziba isisulu sezinhlanzi ezihlukahlukene |
I-Daphnia ngaphansi kwe-microscope.
I-crustacean encane ingeyezinhlobonhlobo ze-planktonic crustacean. Usayizi uncike ohlotsheni. Ingahluka kusuka ku-2 kuye ku-6 mm. Ngenxa yobukhulu bomzimba omncane, kunzima ukubona isakhiwo. Isibonakhulu sizosiza kulokhu.
Umzimba umise okweqanda. Ezinhlangothini zombili kukhona ifreyimu ekhethekile. Imele ukuvikelwa kwezitho zangaphakathi. Izitho zokuhogela ziyizimpondo ezisekhanda. Ngosizo lwawo, amazeze ayakwazi ukusunduza, ukubhukuda, ukugxuma.
Kunemilenze esifubeni. Kudlula ulwelwe namagciwane. Amazeze akwazi ukuphefumula ngamasaka egill. Ama-gill sacs anama-bristles asebenza njengesihlungi.
Kunezinhlobo ezingaphezu kuka-150 zama-cladoceans. Ku-latitudes yethu ungabona:
- i-magnu - izinhlobo ezinkulu kakhulu;
- i-pulexa - inosayizi ojwayelekile;
- imayini - encane.
Kukhona njalo ukudla kwezitshalo esiswini. Iqukethe izakhi zokulandelela eziwusizo ezidingwa izakhamuzi zase-aquarium.
Indawo
Indawo evamile yokuhlala amachibi amile. Bangahlala kokubili echibini nasechibini elijulile. Ngisho ne-Antarctica ebandayo injalo.
Esinye sezimo eziyinhloko ukuba khona kwamanzi ahlanzekile amile anenani elincane lenhlabathi.
Amanzi angaphansi anesandla ekuhluzeni inhlabathi kanye nolwelwe oluhlala emathunjini.
I-Daphnia: isihlungi semvelo.
Lokhu kuholela ekuvaleni. Ngokuba khona kwama-crustaceans emanzini, kuyacaca ukuthi ihlanzekile kangakanani ichibi, ichibi, umfula. Amanzi angaphansi anesandla ekuhluzeni inhlabathi kanye nolwelwe oluhlala emathunjini. Lokhu kuholela ekuvaleni.
Ezinye izinhlobo zihlala phansi, zidla izingxenye ezifile zokudla kwezitshalo kanye nezinsalela zezilwane ezingenamgogodla. Kwesinye isikhathi zingabonakala emachibini nasemigodini enamanzi. Ekukhanyeni okukhanyayo, ama-crustaceans acasha ekujuleni. Lezi zinambuzane zivame ukutholakala amachibi namachibi.
Ukudla kwe-Daphnia
Daphnia emanzini.
Ukudla okuyinhloko kuqukethe imvubelo namagciwane aluhlaza okwesibhakabhaka. Iqoqo elikhulu le-unicellular lingatholakala endaweni yokugcina izimbali, lapho kuhlala khona izinhlanzi ezimbalwa. Futhi zidla ama-ciliate nama-detritus.
Ukuhlunga kwamanzi kwenzeka ngenxa yemilenze ye-pectoral. Ngemuva kwalokhu, ukudla kungena emgodini wesisu, bese kungene emthonjeni. Izindlala zamathe kanye nokuphuma kwezindebe ezingenhla kunomthelela ekunamatheleni kwezinhlayiya zokudla zibe isigaxa.
Izinga lokuhlunga labantu abadala lisuka ku-1 kuye ku-10 ml phakathi nosuku. Isisindo somzimba sithinta inani lokudla. I-magna endala iyakwazi ukudla u-600% wesisindo somzimba wayo.
Umjikelezo wokuphila
Ikhono lokuzala alidingi ukuvundiswa. Izinsikazi zinekamelo lokuzala. Ivikelwe emaphethelweni egobolondo. Izimo ezivumayo zivuna ukubekela amaqanda angama-50 kuya kwayi-100 angavundile. Emigodini, ukukhula kwabesifazane kwenzeka. Okulandelayo, abesifazane baphuma emgodini.
Kwabesifazane, i-molting iqala. Ezinsukwini ezimbalwa kamuva, inqubo yokukhiqiza iphindaphindiwe ngosizo lwabantu abadala. Owesifazane oyedwa angaba nabantwana abangafika ku-25 ngesikhathi sokuphila kwakhe. Ngenxa yalokhu, umbala we-reservoir uba bomvu.
Ekwindla, abesilisa baqala ukuhlanganyela kule nqubo. Igobolondo elivundisiwe liminyene kakhulu. Iyakwazi ukumelana nesithwathwa esinzima kanye nokomisa kwemithombo yamanzi.
Ngokuqala kwentwasahlobo, ukuzala kuphindaphindwa ngenxa yabesifazane. Abantu abasha banesimo somzimba esihlukile. Isikhathi sokuphila se-daphnia enkulu yizinyanga ezi-4 kuya kwezi-5. Abanye abameleli bangafinyelela amaviki ama-3.
izitha zemvelo
Izitha yilezo ezidla izilwane ezincane. Izitha zemvelo zihlanganisa:
- izinhlanzi ezincane;
- gazinga;
- iminenke;
- amaxoxo;
- izibungu ezintsha;
- ezinye izakhamuzi ezizingelayo.
Izimo zokuzalanisa
Ungakwazi ukuzalanisa i-daphnia ekhaya. Amanye amathiphu:
- amanzi kufanele abe nombala oluhlaza okotshani noma okhanyayo;
- abanye abamele indawo yokugcina amanzi abavunyelwe ukungena. Ngokwesibonelo, amaCyclopes;
- ukudla okuyinhloko kufanele kube ulethisi owomile noma amagilebhisi;
- ukondla ngemvubelo ye-baker, egayiwe ngaphambili futhi ihlungwe nge-cheesecloth;
- kwanele ukudonsa amanzi echibini lapho kukhona abantu abangu-50. Ukudla okuphekiwe kwenezelwa kula manzi;
- sebenzisa isitsha sengilazi, kodwa usibeke kude nokukhanya kwelanga;
- ukunamathela emazingeni okushisa kusuka ku-20 kuya ku-24 degrees Celsius;
- hlanza futhi ushintshe amanzi ukuze ugweme ukuqoqwa kwemfucumfucu noma udaka phansi;
- sebenzisa amanzi angenayo i-chlorine nokungcola kwamakhemikhali.
Izinzuzo Daphnia
I-Daphnia inokuqukethwe okuphezulu kwamaprotheni. Ama-amino acid akhuthaza ukukhula nokuthuthuka ngokushesha. Ngokuvamile zengezwa ekudleni kwezinhlanzi ezomile. Kulokhu, ingxenye yesisindo ingamaprotheni.
isiphetho
I-Daphnia iwukudla okubalulekile kwezinhlanzi zase-aquarium, ezithengiswa ezitolo. Ngenxa yokudla okuphilayo, ukugula kuyehla futhi ukuzivumelanisa nezimo ezintsha kulula. Kodwa-ke, uma uthanda, ungazizalela wena.
