I-Amano shrimp (iCaridina multidentata) ingeyesigaba se-crustacean. Lolu hlobo luvame ukubizwa nge-AES (Algae Eating Shrimp) - izimfanzi "zasolwandle". Umklami we-aquarium waseJapan u-Takashi Amano usebenzise lezi zimfanzi ezindaweni zezinto zokufakelwa ukususa ulwelwe emanzini. Ngakho-ke, yaqanjwa ngokuthi i-Amano Shrimp, yaqanjwa ngegama lomhloli wamazwe waseJapan.
Izimpawu zangaphandle zezimfanzi ze-Amano.
Izimfanzi ezingama-Amano zinomzimba ocishe ubonakale wombala oluhlaza okotshani, onamabala abomvu ngokubomvu ezinhlangothini (0.3 mm ngosayizi), aphenduke kahle abe yimivimbo emide. Umugqa olula uyabonakala ngemuva, oqala ukusuka ekhanda uye ekugcineni kwe-caudal. Abesifazane abavuthiwe bakhulu kakhulu, banobude bomzimba obungu-4 - 5 cm, lapho kuhlukaniswa khona izindawo ezinde kakhulu. Abesilisa bahlukaniswa ngesisu esincane kanye nosayizi omncane. Umbala wekhava le-chitinous unqunywa ukwakheka kokudla. Izimfanzi ezidla ulwelwe kanye ne-detritus zinombala oluhlaza okotshani, kuyilapho lezo ezidla ukudla kwezinhlanzi ziba bomvu.
I-Amano shrimp isakazeka.
Izimfanzi ze-Amano zitholakala emifuleni yamanzi asezintabeni abandayo engxenyeni eseningizimu emaphakathi neJapane, egelezela olwandle iPacific. Ziyasatshalaliswa nasentshonalanga yeTaiwan.
Ukudla kwe-Amano shrimp.
Ukudla kwe-Amano shrimp ngokudla okuyi-algal fouling (filamentous), udle i-detritus. E-aquarium, bondliwa ngokudla kwezinhlanzi okomile, izibungu ezincane, ama-brine shrimp, ama-cyclops, i-zucchini echotshoziwe, isipinashi, ama-bloodworms. Ngokushoda kokudla, imfanzi yama-Amano idla amaqabunga amancane ezitshalo zasemanzini. Ukudla kunikezwa kanye ngosuku, ungavumeli ukudla ukuthi kumile emanzini ukugwema ukungcoliswa kwamanzi ase-aquarium.
Incazelo yemfanzi yama-Amano.
Izinhlanzi ezingama-amano ziyizinto ezibalulekile zokuhlanza ama-aquariums ekukhuleni kwe-algal.
Izici zokuziphatha kwezimfanzi ze-Amano.
Izimfanzi ze-Amano zivumelaniswa nendawo yazo yokuhlala futhi zifihle ngokuphelele phakathi kwezitshalo zasemanzini. Kodwa-ke, kunzima ukuyithola. Kwezinye izimo, lapho ama-aquarists, engazitholi izimfanzi emanzini, anquma ukuthi ama-crustaceans afile futhi ahambisa amanzi, futhi imfanzi elahlekile itholakala ngokungalindelekile iphila ezindaweni eziphansi.
Izimfanzi ze-Amano zicasha ezihlahleni eziminyene zezitshalo zasemanzini ezinamaqabunga amancane, lapho zizizwa ziphephile khona. Bagibela ngaphansi kwamatshe, izinkuni ezikhukhulwayo, bacashe kunoma yimaphi ama-nooks acashile. Bakhetha ukuba semanzini agelezayo aqhamuka kusihlungi bese bebhukuda bamelane nesikhathi samanje. Kwesinye isikhathi izimfanzi ziyakwazi ukushiya i-aquarium (imvamisa kakhulu ebusuku), ngakho-ke isiqukathi esinezimfanzi sivaleka ngci, futhi nohlelo lokugcinwa kwe-aquarium lubekwa ukuze ama-crustaceans angakwazi ukugibela kuzo. Ukuziphatha okunjalo okungenacharacteristic kukhombisa ukwephulwa kwemvelo yasemanzini: ukwanda kwe-pH noma izinga lama-protein compounds.
Izimo zokugcina ama-Amano shrimp ku-aquarium.
Izimfanzi ze-Amano azifuneki ngokuya ngezimo zokugcina. Ku-aquarium enamandla angaba ngamalitha angama-20, ungagcina iqembu elincane labantu. Ukushisa kwamanzi kugcinwa ku-20-28 degrees C, PH - 6.2 - 7.5, ngokusho kweminye imibiko, ama-crustaceans asabela kabi ekukhuleni kokuqukethwe kwezinto eziphilayo emanzini.
Ama-shrimps ama-Amano agcinwa ndawonye nezinhlobo ezincane zezinhlanzi zasemanzini, kepha acasha emahlathini kusuka kuma-barbs asebenzayo. Udinga ukwazi ukuthi ezinye izinhlobo zezinhlanzi, isibonelo, izikali, zidla imfanzi. Imfanzi ngokwazo ayiyona ingozi kwabanye abantu abahlala e-aquarium. Zinamazipho amancane kakhulu afanele ukukha ulwelwe oluncane. Kwesinye isikhathi imfanzi iyakwazi ukuphatha into enkulu yokudla ngokusonga imilenze yayo futhi iyisize ihambe ngomsila wayo.
Ukuzalela i-Amano Shrimp.
Izinhlanzi ezingama-Amano zivame ukubanjwa endle. Ekuthunjweni, ama-crustaceans awakhiqizi ngempumelelo enkulu. Kodwa-ke, kungenzeka ukuthola inzalo yezimfanzi e-aquarium uma kunezimo ezibonwayo. Insikazi inomphetho obanzi we-caudal nomzimba ocacile ocacile ezinhlangothini. Unganquma ubulili bezimfanzi ngezici zomugqa wesibili wamabala: kwabesifazane zihlangene, zifana nomugqa ophukile, emadodeni, amabala avezwa ngokusobala, ayindilinga ngokuma. Ngaphezu kwalokho, abesifazane abavuthiwe ngokocansi babonwa ngokuba khona kwesakhiwo esikhethekile - "isihlalo", lapho amaqanda evuthwa khona.
Ukuthola inzalo ephelele, izimfanzi kufanele zondliwe kakhulu.
Owesifazane uheha owesilisa ngokukhwelana, akhiphe ama-pheromones emanzini, owesilisa ubhukuda kuqala azungeze yena, bese ejikela phezulu bese enyakaza ngaphansi kwesisu ukukhipha isidoda. Ukukhwelana kuthatha imizuzwana embalwa. Lapho kukhona abesilisa abaningana, ukukhwelana kwenzeka ngamadoda amaningana. Ezinsukwini ezimbalwa kamuva, insikazi iyazala bese iyanamathela ngaphansi kwesisu. Insikazi iphatha "isikhwama" esine-caviar, esiqukethe amaqanda afinyelela ezinkulungwaneni ezine. Amaqanda asathuthuka anombala oluhlaza okwephuzi ngombala futhi abukeka njengomsila. Ukukhula kwemibungu kuthatha amasonto amane kuya kwayisithupha. Insikazi ibhukuda emanzini enokuqukethwe okwanele komoya-mpilo emanzini, ihlanze futhi ihambise amaqanda.
Ezinsukwini ezimbalwa ngaphambi kokuvela kwezibungu, i-caviar iyakhanya. Ngalesi sikhathi, amehlo emibungu ekhulayo angabhekwa emaqandeni ngengilazi yokukhulisa. Futhi ukukhishwa kwezibungu kungalindelwa ezinsukwini ezimbalwa, kuvame ukwenzeka ebusuku hhayi ngasikhathi sinye. Izibungu zibonisa i-phototaxis (ukusabela okuhle ekukhanyeni), ngakho-ke ziyabanjwa ebusuku, zikhanyise i-aquarium ngesibani, bese zimunca ngepayipi. Kungcono ukutshala owesifazane ozala ngokushesha ngokuhlukile esitsheni esincane, izimfanzi ezincane zizophepha.
Ngemuva kokuvela kwesibungu, owesifazane ubuyiselwa e-aquarium enkulu. Ngemuva kwesikhashana, uyaphinda futhi ahlangane, bese elolongwa, bese ethwala ingxenye entsha yamaqanda kuye.
Izibungu ezichanyuselwe zingu-1.8 mm ubude futhi zibukeka njengamazeze amancane asemanzini. Ziziphatha njengezidalwa ze-planktonic futhi ziyabhukuda ngezitho zazo zicindezelwe emzimbeni. Izibungu zihamba zibheke phansi bese kuthi kamuva zithathe indawo evundlile, kepha umzimba unesimo esigobile.
Imfanzi yabantu abadala i-Amano ngokwemvelo ihlala emifudlaneni, kepha izibungu ezivelayo zithathwa yimanje zingene olwandle, zidla i-plankton futhi zikhule ngokushesha. Ngemuva kokuphothulwa kwe-metamorphosis, izibungu zibuyela emanzini amasha. Ngakho-ke, lapho kuzaliswa imfanzi ye-Amano e-aquarium, kuyadingeka ukuthi ubheke izimo zokukhula kwezibungu, ngosuku lwesishiyagalombili zibekwa ku-aquarium enamanzi olwandle ahlungiwe anomoya omuhle. Kulokhu, izibungu zikhula ngokushesha futhi azifi.
