Gammarus - si youma chakudya ...

Anthu kapena anthu ena Aquarium anali pafupifupi onse. Wina zikugwira nsomba kuswana, ndi zina anachitira ndi cholakwika, ndi lachitatu monga nkhono zambiri zachinsinsi. Choncho, pafupifupi aliyense amadziwa kuti gammarus - chakudya. Koma sizinali chakudya adabadwa! Choncho chimene chimapanga nyama adakali moyo?

malo

Gammarus - ndi crustacean moyo pafupifupi madzi mu dziko lathu. Chodabwitsa n'chakuti mosavuta Amasintha moyo osati atsopano komanso madzi amchere. Iwo ali maina angapo monga nkhanu, Gammarus, gorbunets, bormysh ndipo ngakhale si zamchere shrimp. Okwana pali mitundu yoposa 4.5 zikwi za crustacean mu dziko, koma madzi athu ndi kunyumba kwa makamaka awiri a iwo.

Gammarus - ndi wokhalamo pansi. Iye amakhala pansi miyala, akutsikira ku maenje mu snags, zobisika pakati pa mchenga ndi timiyala pa gombe, pamene gawo la detritus ndi zomera. nkhanu izi sindimakonda kuwala ankaona kukhala mu mithunzi. Anatha kupirira yofanana kwambiri kutentha - kuchokera madigiri kuti 0 26. Ngati dziwe ndi nyumba gammarus, amaundana kwathunthu, nkhanu burrow mu nthaka.

Gammarus - ndi crustacean amene akuti moyo onse padziko chaka. Komanso, iwo anatani chopweteka kwambiri kuipitsa madzi, akufa ndi mpweya osakwanira.

chakudya

aziphedwa Crustacean lawola zotsalira za masamba wagwa ndipo akufa zomera za m'madzi. Kudyetsa makamaka masamba chakudya gammarus ayi ndi zotsalira za nsomba kapena nyama, akufa mu madzi. Nthawi zina nkhanu kudya ndi "abale" awo ang'onoang'ono.

maonekedwe

Live, chimodzimodzi monga gammarus youma ali ndi arcuate thupi yokutidwa chipolopolo. Chitin chimakwirira 14 zigawo. Pa mutu uli ndi maso ili ndi mitundu iwiri iwiri ya tinyanga Zimenezi zimathandiza kuti apeze chakudya, chifukwa iwo ali ziwalo chogwirika. Popita crustacean amasuntha mmbali. Iye yekha amathandiza 18 mapazi. Ndi chifukwa njira kuyenda crustacean ali dzina lina - amphipod.

Pa miyendo thoracic ndi makutu crustacean. M'mimba ndi kumbuyo miyendo zili ndi bristles kusambira ndi chiwongolero. Komanso, kumbuyo kuthandiza crustacean kulumpha, ndi m'mimba - kugwira chakudya. Miyendo yakumbuyo ndi wangayo, kupereka otaya madzi makutu a. Akazi nawonso ali ndi ana thumba mazira ili pa chifuwa.

kubalana

Gammarus kwa akamba, komanso ina, zonse akufunika zakudya, chifukwa mosalekeza kuwonjezeka. Zonse pali chitin kusintha chipolopolo, lomwe lili kukhala thupi kukula kwambiri. Pafupifupi mlungu uliwonse m'chilimwe ndi pa masiku 16-17 m'nyengo yozizira molt amapezeka.

Pogonana nkhanu okhwima kamodzi adathandizapo chitin chivundikiro nthawi 10. Iwo amatha kubereka kangapo pa chaka - zimatengera pa kutentha madzi: ofunda dziwe kuti zimachitika kwambiri kawirikawiri kuposa kuzizira.

Pa spawning, aamuna uthina chipolopolo wamkazi. Wachitapo, iwo akhoza kusambira kupita kwa sabata, kuyembekezera nthawi imene mkazi amayamba kutha. Izi zikachitika, aamuna amathandiza kumaliza ndondomeko, ndiyeno amachititsa mbewu kwa mpanda wa chikwama mazira, pogwiritsa ntchito miyendo m'mimba. Zimenezi zimatenga masekondi ochepa, pambuyo umene disengaged. Akazi kutchera za 30 mazira m'malo lalikulu ana thumba.

Osauka wosabadwa wa milungu 2-3, kenako thumba kunja nkhanu athanzi.

katundu chopatsa thanzi

Amadyetsa gammarus - opereka chakudya cha nsomba za mitundu yosiyanasiyana. Izo ntchito onse pa fakitale nsomba, ndi kudyetsa Aquarium nsomba ndi achule. Gammarus ndi ntchito monga chakudya pamoyo, ndipo monga kuyeretsa dongosolo m'mimba.

Ubwino waukulu Gammarus - mtengo High zakudya ndi zili zofunika kwambiri za carotene. Onani kuti crustacean moyo akhoza kulekerera ena majeremusi kuti zingakhale zovulaza thanzi nsomba. Ndicho chifukwa muyenera kugwiritsa ntchito mazira, zouma kapena chakudya ozonated.

kuswana yokumba

Kudyetsa nsomba ku fakitale nsomba, komanso kupanga chakudya Aquarium okhala sikokwanira kugwira nkhanu m'mitsinje osiyana. M'pofunika kukhazikitsa kotunga mosadodometsedwa a mtundu wa chakudya. Chifukwa chaichi pali minda wapadera nawo kotunga zakudya za mitundu yosiyanasiyana ya Aquarium nsomba ndi achule.

Kuti nkhanu kukhala kwambiri amaona, kukumba ngalande yaitali za masentimita 30 m'lifupi ndi kuya. Mkati, kupanga kagawo kakang'ono yaing'ono. Nyama ntchito monga chakudya zinyalala. Kumbukirani kuti nyama ayenera kukhala watsopano, Mulimonsemo, osati lawola. Mu chifukwa nkhanu amatunga mphanga, poyamba anagwira madzi achilengedwe. Popeza copepods kuchulukitsa mofulumira kwambiri, madzi mwachilungamo nthawi yochepa amadzadza michere gammarus. Nsomba chakudya amasankhidwa mosamala kwambiri, kugwira yekha nsomba za kukula ena. Ndi njira imeneyi, mungathe kudyetsa nsomba nkhanu kukula n'koyenera kwambiri. Mwacitsanzo, mumapezeka nsomba wamng'ono angadye kokha amphipods wamng'ono, pamene achikulire waukulu.

Pamene kudyetsa Aquarium nsomba crustacean chakudya youma kukula zilibe kanthu chifukwa zimakhala zosavuta pogaya. Komabe, kuchokera pa mitsinje ana makamaka kuchotsa akulu lalikulu ziweto zikusintha, nakhalabe kupeza mwatsopano chakudya chopatsa thanzi nthawi zonse nsomba ndi akamba.

Pamene kuwachepera njira alipo kukumba zinthu zatsopano, limene likutengera wamng'ono Gammarus ndi ndondomeko akuyamba kuyambira pachiyambi.
