Vabati vehove All uye nevabiki hove nomuzikamwi knot. Asi tinoziva kuti mumiririri uyu haisi gungwa chete, asiwo rwizi. Between izvi zviviri marudzi, pane Misiyano sezvo uhwiro, uyewo zvekunze.

rwizi knot

Ichi mumiririri chokunze zviratidzi akanaka, uye vakawanda kwayo ruvara ane greenish-yellow Hue. Vanewo yakashongedzwa pachena transverse zvisungo. dumbu ravo nguva dzose yakajeka. It ane yakaoma, hombe, unopinza zvimbi. Muswe nechepasi ane ruvara rima, uye kurutivi mupendero zvakasiyana rutsvuku ruvara. Knot muviri laterally compressed. Musoro ichichinja kuita ano. Uyewo, zviri kusiyaniswa maziso duku.

hove ichi haina subspecies, kufanana nedzimwe mhuri. Chokwadi, pane groupers, yakasiyana coloring, ukuru kana zvimwe zvinhu. Asi kusiyana kwakadaro vanogona kuratidza zvipenyu nezvakazvipoteredza mamiriro mvura miviri yavo kudya. Asi chero zvakadaro chiri rwizi munhuwo knot. Chii hove kana muropa, knot hazvigoni kuvhiringidzwa nedzimwe mhando kana mhuri. Hwakura kusvika hafu meter, uye panguva imwecheteyo nokuyera 4.8 pondo. Mupenyu kusvika makore 17. Asi kazhinji musi hombe hove hove asingadi kusvika kukura ichi uye avhareji iri vanenge 15-30 cm. Ndiwo makore-gore mana vanhu. Izvi mhando hove vagere mvura dzakawanda Eurasia.

Life uye Kugadzirwa rwizi anogara

Izvi mudziva-rwizi kwemarudzi dzinodya dzimwe. Iye anogara mumhenderekedzo yegungwa dziri pasi pemvura mumatenhere. Munzvimbo idzi zviri nyore kupa chikafu - zooplankton uye duku duku hove. Asi zvichienderana dziva umo hove knot inogarwa, ayo kudya dzingasiyana. The yakakura dziva, dzakapfuma zvokudya nechigadziko, uye "Muterere" rehove hunowedzera siyana. Muzviitiko izvi, rwunotanga ive "marudzi" vatatu kana vaviri, izvo zvakasiyana pakati kumhanya kukura, dzinogarisana uye zvokudya sezvamunoita. Pedyo pamahombekombe knot iri kukura zvishoma nezvishoma, nokuti zvokudya kwake kunyanya chirimwa uye invertebrate chikafu. Kana knot agare makadzika, kukura kwayo ndiko mhanyisa, izvozvo kazhinji anodya mamwe furaya hove. Saka, kunyange kurarama chete mudziva, nguva kuyaruka zviri vomumuzinda siyana izvi.

zviri kukonzera

Kazhinji Freshwater hove knot anova zvepabonde vakura mumakore maviri kana matatu okuberekwa. Kureba hove panguva ino angava akasiyana chaizvo. Zviri kukonzera nguva dzose kunotanga chitubu pashure chando. Kumaodzanyemba zvikamu iyi inowira muna February uye March ari kuchamhembe munzvimbo dziri May-June. The hadzi mazai ari chirimwa gore rapera. Number mazai zvinosiyana zvikuru uye rinowanikwa mune zviuru 12 kusvika 300. knot akanaka kupona mazai uye mazana. Pamberi caviar kuda dukutu, inopfuura vhiki mbiri. Panongotanga vana vari kutanga zvakatapwa pamusoro plankton. River hove knot (mufananidzo rwataurwa pamusoro) kuita kuti pave kamwe chete pagore.

Marine mumiririri

River uye gungwa bass vari hove dzakasiyana chaizvo. Ikaonekwa yayo chiso kuwanikwa kufanana idzi vamiririri vaviri yepasi pemvura, asi dzomunyika marongerwo uye zvimwe zvinhu zvinova pachena kuti mhando idzi mbiri zvikwata zvakasiyana zvachose. Marine hove grouper (mufananidzo pazasi) anogona kuva maziso makuru uye ruvara rwakati piriviri kutsvuka. Kazhinji, tinoberekwa rakadzika-mugungwa marudzi. date kwokunze kwakadaro kunobatsira hove uchagarireiko kugara semidarkness. Knot, izvo kuchengeta pedyo nemhenderekedzo, maziso kwete zvokuti kukura uye coloring zvasviba. Vanowanzova pamuchinjikwa muenzaniso, asi nezera kunogona kuva chisanyanya kuoneka.

In mhuri groupers ane vanenge 90 marudzi. Size vari zvakare akasiyana chaizvo. Somuenzaniso, ruduku chete anokura 20 masendimita, nepo pakukura mhando iri chitsama kusvika imwe mita. vagari awa angararama kusvika makore 15. Uyewo kuzivikanwa Hove gungwa bass ndiro zita wechipiri "smarida".

Zvinozivikanwa kuti panguva achicheka rehove vanofanira kungwarira chaizvo, kunyanya kana kwacho rinoitwa pasi mudziyo. Spines, izvo anowanikwa Miti iyi, anogona kuva nengozi. Kukuvara uku kunowanzoita kuti matambudziko kuti arambe kwevhiki dzinoverengeka, uye dzimwe nguva kwemwedzi. Dzimwe nguva, kukuvara ichi kunogona kusiya chinhu zvakakanganwika zvose ake upenyu Somuenzaniso, nomunwe hunoguma kushanda.
