Umnenke we-Helena: ukugcinwa, ukuzalanisa, incazelo, isithombe, ukuhambisana.

Umnenke we-Helena yi-mollusk yasemanzini ahlanzekile enhle kakhulu futhi ewusizo ezojabulisa kakhulu futhi ithakazelise ukuyibuka. Nokho, ezinye izici zokuqukethwe kwayo kufanele zicatshangelwe. Umnenke we-Helena uwuhlobo oludlayo lwe-mollusk emanzini. Imvamisa, ama-aquarists anquma ukuwazalanisa, angakwazi ukulawula inombolo ngokuzimela noma angakwazi ukuqeda ngokuphelele iminenke yezinambuzane ewele ku-aquarium, ngokwesibonelo, ama-phys, amakhoyili, i-melania.

INCAZELO

I-Clea helena (i-Meder e-Philippi, 1847), eyake yabizwa ngokuthi i-Anentome helena, ingenye yezinhlobo eziyisithupha zohlobo lwe-Clea oluqoshwe eMalaysia, Indonesia, Thailand naseLaos. Ekuqaleni, i-mollusk yachazwa esiqhingini saseJava (Van Benthem Jutting 1929; 1959; Brandt 1974). U-Clea helena uyilungu lomndeni wakwaBuccinidae, i-marine gastropod mollusk. Indawo yayo ayigcini emifuleni kuphela, umnenke uhlala emachibini nasemachibini (Brandt 1974).

Abameleli bohlobo lwe-Clea babhaliswe e-Asia emathafeni e-alluvial naseduze nezindawo ezinkulu zamanzi, isibonelo, i-Ayeyarwaddy River Delta (Myanmar), umfula i-Mekong (Indochina), umfula i-Chao Phraya (Thailand) nezinye izinhlelo ezinkulu zemifula namachibi. yaseMalaysia, Brunei kanye ne-Indonesia (Sumatra, Java , Kalimantan, SiputKuning, 2010). Abantu bemvelo abatholakali kwezinye izindawo,

kodwa-ke, lolu hlobo selutholakala yonke indawo phakathi kwama-aquarists eNyakatho Melika, eYurophu nase-Asia. I-Alluvial plain – ithafa elivela ngenxa yokunqwabelana kwemifula emikhulu. Ikakhulukazi amathafa e-alluvial aphakama lapho imifula izulazula ezindaweni ezingaphansi kwe-tectonic. Emvelweni, i-helena ihlala ngaphansi kwamachibi angcolile, ngakho-ke ayihambisani nokwakheka kwamakhemikhali emanzini. Nokho, njengoba lolu hlobo luhlala ezindaweni ezishisayo, amazinga okushisa aphansi luyalubulala.

Okuqukethwe komnenke

Umthamo wamalitha angu-3-5 anele ukuba khona okunethezeka komuntu oyedwa, kodwa kungcono ukunikeza isikhala esiningi - kusuka kumalitha angu-15. Kulokhu, u-Helena uzobukeka ecacile futhi enempilo. Ukugcinwa kweminenke kufanele kwenzeke emanzini ngezinga lokushisa lika-23-27 ° C. Uma izinga lokushisa lehla liye ku-20 ° C noma ngaphansi, khona-ke i-shellfish ngeke

izokwazi ukukhiqiza kabusha. Kuyafaneleka ukunakekela ezinye izimfanelo zamanzi: i-acidity yamanzi kufanele ibe ku-7.2-8 pH; ubulukhuni bamanzi - kusuka ku-8-15. Ukunakwa ngokukhethekile kufanele kukhokhwe ekukhethweni kwenhlabathi. KuHelen, isihlabathi noma amatshe azokwenza. Ngokungafani nama-mollusk amaningi, lolu hlobo alugubhi ngokuphelele emhlabathini; umnenke we-Helena ufuna ukudla kuwo.

I-aquarium yomphakathi akuyona indawo ekahle yezimbaza ezisanda kuthengwa, ngeke zikwazi ukuthola inani elifanele lokudla futhi cishe zizofa. Kuyoba okulungile uma ukugcinwa ezigabeni zokuqala zokuphila kwenzeka endaweni ehlukile ye-aquarium, lapho iminenke ingakhula ibe ngu-1 cm. Uma kukhona ama-mollusk amaningi amancane (i-melania, amakhoyili) ku-aquarium, ungakhohlwa ngokudla kukaHelen. Uma zingatholakali, khona-ke noma yikuphi ukudla okucebile amaprotheni kuzokwenza.

Izidingo zamanzi

Kumele kuqashelwe ukuthi umnenke we-Helena awuthobeki ngokuphelele. Okuqukethwe kwayo, ngaphansi kwemithetho ethile, akudali izinkinga. Amalitha amahlanu amanzi anele umnenke owodwa, kodwa kungcono uma unendawo ekhululekile - kufika kumalitha angamashumi amabili. Qiniseka ukuthi amanzi aqinile. Emanzini athambile, umnenke mubi, ngoba igobolondo lawo lidinga amaminerali. Izinga lokushisa lamanzi elinethezekile lingama-21-23°C ngaphezu kweqanda.

Uma lehla ngaphansi kuka-+19°C, u-Helena angase ayeke ukudla. Ungatshala noma yiziphi izitshalo ku-aquarium, ngoba iminenke ayinandaba nayo ngokuphelele. Ikhwalithi yomhlabathi ibaluleke kakhulu. Ngokungafani nezinye izinhlobo zeminenke, i-helens ayigobi ngokuphelele kuyo, kodwa bheka ukudla lapho, ngakho-ke isihlabathi noma amatshe amahle afaneleka kakhulu kule njongo.

Ukudla

Umnenke we-helena ungumlandeli omkhulu wama-mollusk anjengamakhoyili, ane-fizy futhi, kancane kancane, i-melania. Ngemva kokukhetha isisulu, u-Helena welula i-proboscis evula umlomo egobolondweni futhi uqala ukumunca okuqukethwe ngokoqobo, eshiya igobolondo elingenalutho ngenxa yalokho. Eminenke emikhulu, ngokwesibonelo, iminenke noma i-tilomelanium, ayihlaseli, ngoba ayikwazi nje ukuyibamba. Umnenke odla inyama awuthinti ngisho neminenke emincane kakhulu, i-proboscis engakwazi ukukhasa emagobolondweni ayo.

U-Helena angakwazi futhi kufanele adliwe ngokudla okwengeziwe, ikakhulukazi uma engaqalanga ukudla iminenke efuyiwe. Badla izinsalela zokudla kwezinhlanzi, baziphathe ngenkuthalo ama-bloodworms, ama-shrimp eqandisiwe, ukudla kwe-catfish. Emvelweni, u-Helena uvame ukudla inyama efile. Lokhu kungenzeka futhi emanzini - abantu abagula kakhulu noma abafile bangadliwa umnenke.

Ukuhambelana

U-Helena ubeka usongo eminenke emincane kuphela. Uzwana ngokujwayelekile nezinhlanzi, futhi uma ehlasela, kuphela kumuntu ogula kakhulu futhi obuthakathaka. Ama-Swift shrimp nawo awafakiwe ohlwini lwezisulu zika-Helena, kodwa, njengasendabeni yezinhlanzi, abameleli ababuthakathaka abangazange babekezelele i-molting bangaba inhloso. Izinhlobo ezingavamile zama-shrimp zigcinwa ngokuhlukana.

Njengeminenke eminingi, i-helena idla amaqanda ezinhlanzi, kodwa ayiwathinti ukuthosa: imvamisa ithambile kakhulu, futhi umnenke ngeke uwabambe.

Izindaba ezinhle kubathandi bezitshalo ze-aquarium! Iminenke eminingi, lapho kuntuleka ukudla, iqala ukuhlasela ulwelwe, ibangele ukulimala okukhulu. Iminenke ye-Helena ayinandaba nhlobo nezitshalo.

Breeding

Iminenke kaHelen ithanda ubulili obuhlukile, ngakho ukukhiqizwa kwayo kudinga ukuba khona kwabantu ababili. Njengasendabeni yeminenke, akunakwenzeka ukuhlukanisa owesifazane kowesilisa, ngakho-ke kungcono ukuthenga izingcezu eziningana ngesikhathi esisodwa, ukuze phakathi kwabo kube khona abantu abathandana nabobulili obuhlukile. Ezimweni ezinhle, zizalela ngokuzimisela: insikazi eyodwa ingabekela amaqanda angaba ngu-200 ngonyaka.

Ukulungiselela ukukhwelana, iminenke ayihlukaniseki isikhathi esithile: iyakhasa ndawonye, ​​idla, igibele yodwa. Ukuthola ama-helens ambalwa athuthukile, kungcono ukuwatshala endaweni ehlukile ye-aquarium. Umakhelwane onezinhlanzi ezisebenzayo uzoba nomphumela ocindezelayo kowesifazane, futhi ngeke akwazi ukubeka amaqanda.

Ukukhwelana kuyinqubo ende, kungathatha amahora ambalwa. Ngemva kwalokho, insikazi ibeka iqanda layo endaweni eqinile: amatshe, i-driftwood noma eminye imihlobiso yase-aquarium. Kungumcamelo osobala, ngaphakathi kwawo kufihlwe i-caviar ephuzi. I-Caviar ivuthwa phakathi kwamasonto angu-2-4.

Lapho umnenke omncane uchanyuselwa, ngokushesha uzithola uphansi, ngemva kwalokho ucashe emhlabathini. Lapho ihlala izinyanga ezimbalwa ize ifinyelele usayizi wamamilimitha angu-5-8.

U-Helena ungumsizi ophelele we-aquarium ukunciphisa umbala oyisiphepho wama-clam adla yonke into ezungezile. Okuqukethwe kwayo akukhathazi nakancane, futhi ukubuyekezwa okuningi kufakazela ukuthi umhlaseli omncane ngeke nje ube nenzuzo, kodwa futhi uzoba yinto emangalisayo yokuhlobisa i-aquarium.
