Sizachabechabe zomwe akunena za asodzi - ali okangalika, chifukwa amakhala okonzeka kuwedza nthawi iliyonse ya chaka kapena tsiku. Pali nsomba zambiri m'mitsinje ndi m'nyanja zathu. Zimasiyana osati maonekedwe a nsomba, kulawa, koma, ndithudi, m'njira zowagwira. Imodzi mwa zikho zodziwika bwino zophera nsomba ndi nsomba za pike.
Maonekedwe a Pike ndi malo okhala
Ndi wa banja lapaike. Nsomba za mtsinje wa Pike chilombo, m'matupi athu amadzi amawerengedwa kuti ndi amodzi mwamphamvu kwambiri. Pakati kukula kukwera mpaka 1 mita mpaka 5 kg. Koma anthuwa adalembedwa mpaka 1.5 mita kukula kwake mpaka 35 kg. Thupi lake ndi lopangidwa ndi torpedo, mutu wake ndi wokulirapo pakamwa. Nsagwada zokhala ndi mizere ya m'munsi ya mano zimayenda patsogolo pang'ono.
Pike mano lakuthwa kwambiri, pali zambiri, m'mizere ingapo, ndipo zimapezeka osati pa nsagwada, komanso pakamwa, lilime ndi mitsempha. Nsagwada zimakonzedwa kuti pogwira nyama, mano amalowa pakamwa, koma ngati wovulalayo ayesera kuthawa, amadzuka ndikuigwira.
Pa nsagwada m'munsi mano akhoza m'malo - akale ndi atsopano. Kuphatikiza apo, zonse zimamera nthawi imodzi, mano otsala omwe ali m'malo ofewa kumbuyo kwa dzino lothandizalo. Ikamatuluka, mano "osungira" amachoka ndipo amatenga danga laulere.
Mtundu wa pike ukhoza kukhala wosiyanasiyana, kutengera chilengedwe. Mtundu waukulu wa masikelo ang'onoang'ono a pike ndi imvi, ndipo mawanga pathupi amatha kukhala osiyana, kuyambira achikaso mpaka bulauni. Msana nthawi zonse umakhala wakuda, mawanga m'mbali mwake amapanga mikwingwirima kudutsa thupi. Akuluakulu amakhala ndi thupi lakuda.
Nsomba zomwe zimakhala m'madzi akuda am'matumba amchere zimawoneka zakuda kuposa zina zonse. Zipsepse zapawiri ndizalanje ndipo nthawi zambiri sizofiira, zopanda bulauni kapena zotuwa. Mtundu wa amuna ndi akazi ndi wofanana, mkazi amatha kusiyanitsidwa ndi wamwamuna ndi kukula kwake kwakukulu ndi chida china cha genitourinary system.
Pike amapezeka mdera lotentha komanso kumpoto. Madzi atsopano a Eurasia ndi North America ndi malo ake. Amapezekanso m'malo amchere amchere, mwachitsanzo, m'mbali mwa nyanja za Baltic ndi Azov, komanso kunyanja ya Black, Aral ndi Caspian.
Kumpoto kuli mitundu ina - Amike Pike, yemwe amakhala mumtsinje wa Amur womwewo. Habitat kumpoto kuchokera ku Kola Peninsula kupita ku Anadyr. Nthawi zambiri zimasungidwa m'mbali mwa nyanja, tchire, nkhalango, zotchinga, pomwe kulibe msanga. Amakhalanso m'madzi ndi mitsinje.
Pike sangapezeke m'madzi akuba, monga dziwe laling'ono. Pike amafuna mpweya wambiri, chifukwa chake sangakhalebe m'nyengo yozizira mosungira pang'ono. Nthawi zambiri, ngakhale atafika kukafika kusefukira kwa madzi mumtsinje, kuzizira kwa nyengo yozizira kumagwira ntchito yawo - zimbalangondo zimamwalira m'madamu ngati amenewa, komanso nsomba zina.
Pofuna kuti izi zisachitike, asodzi eniwo amayesetsa kusamalira nsombazo - amadutsa mabowo akuluakulu mu ayezi, omwe amaphimba ndi nthambi ndikuwaza chipale chofewa kuti madzi omwe ali mmenemo asazizire nthawi yayitali, ndipo mpweya umatha kulowa mgululi.
Pike moyo
Masana, pike nthawi zambiri amakhala pafupi ndi gombe, m'mitengo yamadzi. Amayesetsa kuyandikira kuzinthu zazikulu zomwe zimatha kubisika kumbuyo, komanso nthawi yomweyo, kuti chakudya chisakhale patali kwambiri. Anthu ang'onoang'ono amayesetsa kumamatira ku mabango ndi ndere zina, kumene kumakhala nsomba zazing'ono, zoyenera kudya.
Anthu akuluakulu amakhala ozama, komanso amayesa kupeza pogona ngati matabwa oyenda kapena tchire lodzaza madzi. Pies amakonda kuwala kwa dzuwa, ndipo m'masiku osalala amasambira mpaka kugombe, atanyamula mdima wawo ndikumangokhala chete kwa nthawi yayitali. Nsomba zazikulu sizimayima pafupi ndi gombe, komanso zimayandama pamwamba, zitakakamira m'nkhalango zowuma.
Ngati asokonezeka, amathamangira mokweza, komabe amayesetsa kukhala pafupi ndi "gombe" lawo. Mwa njira, pa kusodza pike, ndizosavuta kuyigwira pa ndodo yopota m'madzi oyera, chifukwa chake muyenera kuyesera kutulutsa udzu. M'magulu osiyanasiyana amadzi, moyo wa ma piki omwe amakhala mmenemo ndi wosiyana pang'ono, komabe, choyambirira kukwera Ndi wakuba komanso wolanda nyama.
Kudyetsa Pike
Pafupifupi kuyambira ali akhanda, makeke amalawa chakudya cha nyama. Ngakhale mwachangu, yemwe chakudya chake chimachokera ku zooplankton, amayesa kusaka mphutsi za nsomba zazing'ono zingapo, ngakhale pakadali pano zili ndi 1.5 cm okha. Kukula mpaka masentimita asanu, ma piki amasinthiratu kudyetsa nsomba. M'nyengo yozizira, ntchito ya pike imachepa kwambiri, izi zimagwiranso ntchito pakudya.
Koma nthawi zonse amasaka momwemo - kubisala tchire kapena udzu, amathamangira nyama yomwe ikusambira. Pike imameza mutu wa nsomba poyamba. Ngati mutha kuigwira kudutsa thupi lonse, ndiye kuti chilombocho chimatembenuzira nsomba, kuti zimumeze mosavuta. Pakadali pano, mano otsuka amatembenukira mwanjira yomwe nsomba imalowa mu pharynx popanda kusokonezedwa.
Ngati nyamayo ikuyesera kuthawa, mano akuthwa amatsutsana nayo ndi maupangiri ndipo wovutitsidwayo adzakhala ndi njira imodzi yokha - m'mimba mwa chikhomo. Pakusaka, Pike amagwiritsa ntchito masomphenya ndi chiwalo chovuta - mzere wotsatira, womwe umapangidwa osati kokha m'litali lonse la thupi, komanso pamutu.
MU zakudya zapikike osasankha kwambiri, amatha kudya chilichonse chomwe angagwire ndikukhazikika pakhosi. Awa ndi nsomba za goby, whitefish, bream, nsomba, roach, crucian carp, ruff, minnow, minnow komanso ma piki ang'onoang'ono. Nthawi zambiri, amadya anzawo, ngati alipo ambiri mosungiramo ndipo ndi ocheperako.
Amadyanso achule, anapiye, ankhandwe, mbalame zam'madzi, ma crustaceans ndi nyama zazing'ono (hares, mbewa, agologolo) ogwidwa m'madzi. M'nyanja zamapiri ku Canada, kumene kuli mapikoko okha, akuluakulu amadya ana awo. Ngati tikulankhula za zilakolako za pike, amadziwika kuti imameza chakudya, chomwe chimapanga 50-65% ya kulemera kwake ndi kukula kwake.
Kubereka ndi chiyembekezo cha moyo wa pike
Nsombazi zimatulukira kumayambiriro kwa masika, madzi oundanawo akangosungunuka. Pike caviar imakhala mu algae pakuya kwa mita 0.5-1. Mkazi amaikira mazira, ndipo amuna amatsagana naye ndikuwapatsa mkaka. Munthu m'modzi amatha kutulutsa mazira 20-200,000. Caviar imakhazikika pa udzu, algae, kenako imagwera pansi ndipo mkati mwa masiku 8-14 mwachangu amachokera pamenepo. Pics amakhala okhwima azaka zapakati pa 2-4.
