Helena nkhono: kukonza, kuswana, kufotokoza, chithunzi, ngakhale.

Nkhono ya Helena ndi mollusk yokongola kwambiri komanso yothandiza yomwe idzakhala yosangalatsa komanso yosangalatsa kuwonera. Komabe, mbali zina za zomwe zili mkati mwake ziyenera kuganiziridwa. Nkhono za Helena ndi mtundu wolusa wa mollusks wamadzi am'madzi. Nthawi zambiri, aquarists amasankha kuwaswana, omwe sangathe kuwongolera chiwerengerocho kapena sangathe kuchotsa nkhono zomwe zagwera mu aquarium, mwachitsanzo, phys, coils, melania.

DESCRIPTION

Clea helena (Meder ku Philippi, 1847), yemwe kale anali Anentome helena, ndi imodzi mwa mitundu isanu ndi umodzi yamtundu wa Clea yolembedwa kuchokera ku Malaysia, Indonesia, Thailand ndi Laos. Poyamba, mollusk inafotokozedwa pachilumba cha Java (Van Benthem Jutting 1929; 1959; Brandt 1974). Clea helena ndi membala wa banja la Buccinidae, makamaka marine gastropod mollusk. Malo ake sakhala ndi mitsinje, nkhonoyi imakhalanso m'nyanja ndi maiwe (Brandt 1974).

Oimira amtundu wa Clea amalembedwa ku Asia m'zigwa za alluvial komanso pafupi ndi mathithi akuluakulu amadzi, mwachitsanzo, Ayeyarwaddy River Delta (Myanmar), Mtsinje wa Mekong (Indochina), Mtsinje wa Chao Phraya (Thailand) ndi mitsinje ina yaikulu ndi nyanja. Malaysia, Brunei ndi Indonesia (Sumatra, Java, Kalimantan, SiputKuning, 2010). Anthu achilengedwe sapezeka kumadera ena,

komabe, mitunduyi yakhala ikupezeka paliponse pakati pa aquarists ku North America, Europe, ndi Asia. Chigwa cha Alluvial - chigwa chomwe chimabwera chifukwa cha kuchulukana kwa mitsinje ikuluikulu. Makamaka zigwa zazikulu za alluvial zimayamba pamene mitsinje ikuyendayenda m'madera a tectonic subsidence. Mu chilengedwe, helena amakhala pansi zauve reservoirs, choncho undemanding kwa mankhwala zikuchokera madzi. Komabe, popeza kuti zamoyozo n’za kumalo otentha, kutenthako kumapha.

Zinthu za nkhono

Kuchuluka kwa malita 3-5 ndikokwanira kukhalapo kwa munthu m'modzi, koma ndibwino kuti mupatse malo ochulukirapo - kuchokera ku malita 15. Pankhaniyi, Helena adzawoneka wokongola komanso wosangalatsa. Kukonzekera kwa nkhono kuyenera kuchitika m'madzi ndi kutentha kwa 23-27 ° C. Ngati thermometer imatsikira ku 20 ° C kapena kutsika, ndiye kuti nkhono sizidzatero.

idzatha kuberekana. Ndikoyenera kusamalira makhalidwe ena amadzi: acidity ya madzi iyenera kukhala mu 7.2-8 pH; kuuma kwa madzi - kuyambira 8-15. Chisamaliro chapadera chiyenera kuperekedwa pa kusankha nthaka. Kwa Helen, mchenga kapena miyala idzachita. Mosiyana ndi nkhono zambiri, mtundu uwu sumakumba pansi; nkhono ya Helena imasakasaka chakudya mmenemo.

Aquarium ammudzi si malo abwino oti angogulidwa kumene, sangathe kupeza chakudya choyenera ndipo amatha kufa. Zidzakhala zolondola ngati kukonza pazigawo zoyamba za moyo kumachitika m'madzi osiyana, pomwe nkhono zimatha kukula mpaka 1 cm. Ngati mu Aquarium pali mollusks ang'onoang'ono (melania, coils), ndiye kuti mukhoza kuiwala za chakudya cha Helen. Ngati palibe, ndiye kuti chakudya chilichonse chokhala ndi mapuloteni chidzachita.

Zofunikira zamadzi

Tikumbukenso kuti nkhono Helena kwathunthu wodzichepetsa. Zomwe zili mkati mwake, malinga ndi malamulo ena, sizimayambitsa mavuto. Malita asanu amadzi ndi okwanira pa nkhono imodzi, koma ndi bwino ngati ili ndi malo ochulukirapo - mpaka malita makumi awiri. Onetsetsani kuti madzi ndi ovuta. M'madzi ofewa, nkhono imakhala yoipa, chifukwa chipolopolo chake chimafuna mchere. Kutentha kwamadzi omasuka kwambiri ndi 21-23 ° C pamwamba pa ziro.

Kutsika pansi pa +19 ° C, Helena akhoza kusiya kudya. Mutha kubzala mbewu zilizonse mu aquarium, chifukwa nkhono sizimakhudzidwa nazo. Ubwino wa dothi ndi wofunika kwambiri. Mosiyana ndi mitundu ina ya nkhono, ma helens samakwirira kwathunthu, koma yang'anani chakudya pamenepo, kotero mchenga kapena miyala yabwino ndiyoyenera kwambiri pazifukwa izi.

Kudyetsa

Nkhono ya helena imakonda kwambiri mollusks monga ma coils, fizy komanso, nthawi zambiri, melania. Atasankha wovulalayo, Helena amatambasula pulojekiti ndi pakamwa potsegula mu chipolopolocho ndikuyamba kuyamwa zomwe zili mkati mwake, ndikusiya chipolopolo chopanda kanthu. Pa nkhono zazikulu, mwachitsanzo, nkhono kapena tilomelanium, samaukira, chifukwa sangathe kuzidziwa. Nkhono zolusa sizikhudza ngakhale nkhono zing’onozing’ono, zimene proboscis yake simatha kukwawira m’zigoba zake.

Helena akhoza ndipo ayenera kudyetsedwa ndi chakudya chowonjezera, makamaka ngati sanayambe kudya nkhono zoweta. Amadya zotsalira za chakudya cha nsomba, amadzichitira okha mphutsi zamagazi, mazira oundana, nsomba zam'madzi. Mwachilengedwe, Helena nthawi zambiri amadya zovunda. Izi ndizothekanso m'madzi am'madzi - anthu odwala kwambiri kapena akufa amatha kudyedwa ndi nkhono.

ngakhale

Helena amangoopseza nkhono zazing'ono. Amakhala bwino ndi nsomba, ndipo ngati aukira, ndiye kuti amadwala kwambiri komanso wofooka. Swift shrimp nawonso sanaphatikizidwe pamndandanda wa omwe adazunzidwa ndi Helena, koma, monga momwe zilili ndi nsomba, oimira ofooka omwe sanalole kusungunula akhoza kukhala chandamale. Mitundu yosowa ya shrimp imasungidwa payokha.

Mofanana ndi nkhono zambiri, helena amadya mazira a nsomba, koma samakhudza mwachangu: nthawi zambiri amakhala ochepa kwambiri, ndipo nkhonoyo sichidzawapeza.

Nkhani yabwino kwa okonda zomera za aquarium! Nkhono zambiri, pakasowa chakudya, zimayamba kumenyana ndi algae, zomwe zimavulaza kwambiri. Nkhono za Helena zilibe chidwi ndi zomera.

kuswana

Nkhono za Helen zimagonana ndi amuna kapena akazi okhaokha, kotero kuti kubereka kwawo kumafuna kukhalapo kwa anthu awiri. Monga momwe zilili ndi nkhono, sizingatheke kusiyanitsa mkazi ndi mwamuna, choncho ndi bwino kugula zidutswa zingapo nthawi imodzi, kuti pakati pawo pakhale kugonana kwa amuna kapena akazi okhaokha. Zikakhala bwino, zimaswana kwambiri: yaikazi imodzi imatha kuikira mazira 200 pachaka.

Kukonzekera kukweretsa, nkhono zimakhala zosalekanitsidwa kwakanthawi: zimakwawira palimodzi, kudyetsa, kukwerana. Kupeza ma heleni angapo omwe apangidwa, ndi bwino kuwabzala mu aquarium yosiyana. Malo okhala ndi nsomba yogwira ntchito adzakhala ndi zotsatira zokhumudwitsa kwa mkazi, ndipo sangathe kuikira mazira.

Kukweretsana ndi njira yayitali, imatha kutenga maola angapo. Pambuyo pake, mkaziyo amayikira dzira pamalo olimba: miyala, matabwa kapena zokongoletsera zina za aquarium. Ndi pilo wowonekera, mkati mwake momwe caviar yachikasu imabisika. Caviar imacha mkati mwa masabata 2-4.

Nkhono yaing’ono ikaswa, nthawi yomweyo imadzipeza ili pansi, kenako imabisala pansi. Kumeneko kumakhala kwa miyezi ingapo mpaka kufika kukula kwa mamilimita 5-8.

Helena ndiye wothandizira wabwino kwambiri wam'madzi am'madzi kuti achepetse mtundu wamphepo wamkuntho womwe umadya chilichonse chozungulira. Zomwe zilimo sizili zovuta konse, ndipo ndemanga zambiri zimatsimikizira kuti nyama yodya nyama yaying'ono sidzakhala yopindulitsa, komanso idzakhala chinthu chodabwitsa cha zokongoletsera za aquarium.
