Gammarus - haisi chikafu yakaoma chete ...

Avo kana dzimwe akwariyamu vageremo vakanga vanenge zvose. Mumwe aidaro maberekero hove, vamwe nayo kapukanana, uye yechitatu akaita zvakawanda zvisinganzwisisiki nedhambakura. Naizvozvo, anenge munhu wose anoziva kuti gammarus - ndizvo zvokudya. Asi akanga asina chikafu akaberekwa! Saka chii chinoumba chisikwa achiri mupenyu?

dzinogarisana

Gammarus - a Crustacean kurarama anenge ose muviri mvura munyika yedu. Zvinoshamisa, nyore nayo zvinoenderana upenyu kwete zvinyoro chete asiwo pane mvura munyu. Chine mazita akawanda, akadai kuti shrimp, Gammarus, gorbunets, bormysh uye kunyange Freshwater shrimp. In zvachose mune vanopfuura zviuru 4,5 mhando Crustacean munyika, asi mvura yedu musha kunyanya vaviri.

Gammarus - a pasi anogara. Anorarama pasi mabwe, anokwira nomumakomba ari snags, akavanda pakati jecha uye hurungudo pamhenderekedzo, apo yakawanda detritus uye zvinomera. crustaceans izvi havadi chiedza chinopenya, achisarudza kuramba ari mimvuri. Kukwanisa kukurira zvinokosha zvakasiyana tembiricha - kubva 0 kusvika 26 inegumi. Kana dziva iri musha gammarus, yaita chando zvachose, crustaceans burrow muvhu.

Gammarus - a Crustacean ane izwi upenyu kumativi ose gore. Mukuwedzera, ivo vanoita zvikuru zvinorwadza kuti kusvibisa mvura, kufa kukwana okisijeni.

chikafu

Crustacean akadya kuorera mazviri zvasara mashizha akawa uye hwemvura akafa zvirimwa. Feeding kunyanya muriwo chikafu gammarus kuramba uye zvisaririra rehove kana mhuka, akafa mumvura. Dzimwe nguva magakanje kudya "hama" dzavo duku.

chitarisiko

Live, saizvozvo riome gammarus ane arcuate muviri rakafukidza deko. Chitin rinofukidza 14 zvikamu. Mumusoro vari riri maziso maviri yegwara tunonzwa, iyo inobatsira kuti kutsvaka zvokudya, nekuti ivo tactile nhengo. Paunenge uchityaira Crustacean runoita padivi. Mabatsiriro pachake 18 tsoka. Akafanirwa kuti nzira kufamba Crustacean ane rimwe zita - amphipod.

On makumbo thoracal vari Crustacean gills. Makumbo Abdominal uye shure vari vakapakata bristles kuti zvokushambira uye gozvo. Mukuwedzera, rwemberi kubatsira Crustacean kusvetuka, uye abdominal - kuchengeta chikafu. Makumbo hadzi tichingotarisira kutamira, ichipa nokuyerera mvura gills. Vakadzi vanewo vavaiti homwe kuti mazai iri pachipfuva.

kubereka

Gammarus nokuti nenjiva, uyewo mamwe ari kuramba vachida kunovaka muviri, nokuti akaramba achiwedzera. Kugara pane kuchinja chitin goko, iyo kutsanya ava kukura muviri kunyatsotevera. Inenge ose vhiki muzhizha uye ose 16-17 mazuva muchando Molt kunoitika.

Sexually crustaceans vakakura vari kamwe wazorodzwa chitin butiro 10 nguva. Vanokwanisa kubereka vana kanoverengeka gore - napo mvura tembiricha: inodziya dziva kuti zvinoitika zvikuru kakawanda kupfuura chando.

Panguva zviri kukonzera, mukono rinonamatira mukadzi nevamwe. Atambura, vanogona kushambira kuti pavhiki, vakamirira nguva apo nehadzi uchatanga kupera. Kamwe ichi kunoitika, mukono kunobatsira kupedza muitiro, uye ipapo chinokonzera mbeu kumasvingo bhegi kuti mazai, achishandisa makumbo abdominal. Izvi zvinotora mumasekonzi mashomanana, pashure icho disengaged. The hadzi mazai anenge 30 asi guru mazana homwe.

Mwana anenge achikura mudumbu vhiki 2-3, pashure izvo bhegi kunze zvakazara kuumbwa crustaceans.

muviri ehupfumi

Feed gammarus - tsime rinokosha zvokudya hove dzakasiyana marudzi. Rinoshandiswa zvose pamusoro fekitari hove, uye zvokudya akwariyamu hove uye amphibians. Gammarus uye kushandiswa senzvimbo inokosha dyisa, uye somunhu pakuchenesa zvomudumbu hurongwa.

The chikuru mukana Gammarus - High muviri kukosha uye chinokosha zviri carotene. Cherechedza kuti Crustacean mhenyu anogona kushivirira vamwe tupukanana kuti anogona kukuvadza utano hove. Ndicho chikonzero uchifanira kushandisa yakagwamba nechando, akaomeswa kana ozonated chikafu.

chakagadzirwa rutoto

Feeding hove kuti fekitari hove, uyewo kugadzirwa inosimbisa akwariyamu vagere, hazvina kukwana kuti abate crustaceans nomunzizi siyana. Zvakakodzera vatange risina kumiswa nerubatsiro kwakadai chikafu. Nokuti chinangwa ichi pane chinokosha mumapurazi zvinobatanidzwa nerubatsiro chikafu rakasiyana-siyana akwariyamu hove uye amphibians.

To crustaceans kuti zvakaisvonaka anzwe, kuchera refu pemigero pamusoro masendimita 30 upamhi nokudzika. Inside, kuita diki niche. The nyama rinoshandiswa sezvo tsvina chikafu. Yeuka kuti nyama inofanira manyoro, chero zvazvingava, kwete kuorera mazviri. In kwaizoita madziva tivate crustaceans, kare abatwa dzinongoitika mumvura. Sezvo copepods muwande nokukurumidza, mvura kumbonyanya pfupi nguva anozadza inotonhorera gammarus. Fish zvokudya vanosarudzwa vanyatsohuongorora, kuredza chete imwe saizi. With nzira iyi, unogona zvokudya hove crustaceans kukura kuti yakakodzera. Somuenzaniso, wechiduku Rainbow anogona chete kudya amphipods diki apo vakuru ndivo kupfuura.

Kana zvokudya akwariyamu hove Crustacean yakaoma zvokudya saizi hazvina basa nokuti nyore chaizvo kuti ukuye. Zvisinei, kubva vana migero kunyanya kubvisa vakuru makuru zvipfuwo ari dzichichinja, uye akaramba kukwanisa kugara kuwana matsva zvokudya zvinovaka muviri kuti hove uye nenjiva.

Kana kupererwa aivapo migero kuchera zviwanikwa itsva, iyo anotakura Gammarus muduku uye muitiro rinotanga kubva pakutanga.
