Chii chinodyiwa nepike

Kune zvinopfuura zvikara zvinokwana kuchamhembe kwehemisphere, mukombe unofarirwa nevabati vehove vazhinji pike, vanoibata muEurasia neNorth America nekubudirira kumwe chete. kunobva pamaitiro ekudya. Kuti ubudirire kubata hove, zvakakosha kuziva kuti pike inodya chii mudziva, mutsara wemakumbo anopiwa zvinoenderana neizvi.

Pike features

Mumvura yakachena yekuchamhembe kwehemisphere, kusanganisira mumakungwa egungwa reBaltic neAzov, anglers anofara kubata pike. Chikara chinogona kukura kusvika mita imwe nehafu muhukuru, nepo uremu hwayo hunenge hunenge 35 kg. Hofori dzakadaro hadzina kunyanya kuwanda, sarudzo dzinosvika kumita kureba nehuremu hwe7-10 kg dzinoonekwa semukombe, asi hazvisi nyore kuvaburitsa kunze.

Zviri nyore kusiyanisa pike kubva kune vamwe vamiririri veichthyofauna, inotakura zvishoma zvakafanana kune vekwake. Rudzi rwemuviri runogona kusiyana zvichienderana nehunhu hwedhamu, kune vanhu vane ruvara urwu:

• grayish;
• greenish;
• shava

Muchiitiko ichi, mavara uye mitsetse yemavara akareruka achagara aripo mumuviri wese.

Chinhu chakasiyana chepike chimiro chemuviri, chinofanana ne torpedo. Musoro wakarebesawo, muromo une simba une mazino madiki akawanda anogona kuruma nemuzvinhu zvakawanda.

Mazino epike anogara achivandudzwa, vakwegura vanowira kunze, uye vaduku vanokura nokukurumidza zvikuru.

Ichthyologists inosiyanisa pakati pemhando mbiri huru dzepike dzinogara mumadziva edu, ma anglers ane ruzivo anozopawo misiyano mikuru.

Nzvimbo dzekupaka dzezvikara hadziwanzo chinja, kazhinji dziri nyore kuwana zvese muchando uye muzhizha munzvimbo imwechete.

Kubereka kunoitika nenzira dzakasiyana, yekutanga kubereka vanhu vadiki vasvika pakuyaruka, kureva, avo vane makore mana. Nechikadzi chimwe chete, varume 4-3 vanoenda kunzvimbo yekuisa mazai, uye kana pike yakakura, nhamba yevanokwikwidza inogona kusvika masere. Nzvimbo dzeizvi dzinosarudzwa dzakanyarara dzine miti yakawanda. Kubudirira kwemazai kunotora kubva pa4 kusvika kumazuva gumi nemashanu, zvinoenderana zvakananga nekupisa kwemvura mumudziyo. Iyo yakanyungudutswa fry haigoni kumira mberi, kwemavhiki mashomanana ekutanga ivo vachadya pane crustaceans. Imwe nehafu centimita pike haizorasikirwi nefry uye crucian caviar, haizozvidza carp mune iyi fomu. Hupenyu hunotevera kutenderera hucharatidza pike sechikara chakazara, hapazovi nekuzorora mudura kune chero munhu.

Vanodyei muzvisikwa?

Wese munhu angangove anoziva zvinodyiwa nepike, anofara kutyaira chero ichthy anogara kubva mudziva. Nheyo yezvokudya ndeye marudzi ose ehove dziri mune imwe nzvimbo yemvura uye kwete chete. Zvakaonekwa kuti anofarira hove dzine muviri wakareba, vanhu vakatenderedza havana basa nazvo.

Iyo pike haingapfuuri:

• roaches;
• bleak;
• rudd;
• chub;
• dance;
• crucian carp;
• perch;
• rattan;
• sandblaster;
• minnow;
• bull;
• ruff.

Asi izvi zviri kure nekudya kwakakwana, dzimwe nguva anovhima mhuka. Mumuromo wepike zvinogona kuve nyore:

• frog;
• mouse;
• rat;
• squirrel;
• precipitated;
• crayfish;
• Coolies.

Uye hazvidi zvachose kuti munhu akabatwa ave mudiki, mhuka inodya mhuka inogona nyore kurarama nemunhu ari pakati nepakati.

Kudya kwemhuka duku

Fry ichangobva kuchochonywa kubva kumazai inenge yakareba 7 mm. Munguva iyi, ivo vachashingaira kudya crustaceans kubva mudura, kureva daphnia uye cyclops. Zvokudya zvakadaro zvichavabvumira kukura uye kukura nokukurumidza zvakakwana.

Apo fry inokura kaviri, kudya kwayo kuchachinja zvakanyanya, vagari vaduku venzvimbo yemvura vachave vasina kufarira. Munguva iyi, vana vepike vari kushingaira kudzingirira macrucians achangoburwa uye carps, inotyisa perch.

Cannibalism

Ko piki inodyei kana yakura? Pano zvaanoda zvakakura kwazvo, kunze kwemarudzi ane rugare ehove, haazopi zororo kuhama dzake duku. Cannibalism yepike ndiyo tsika yehupenyu, kune madziva muAlaska neKola Peninsula, uko, kunze kwepike, hapasisina hove, mhuka inodya inokura uye inokura ipapo nekudya madzinza ayo.

Inodya algae here

Vazhinji vanotsauswa nezita rekuti "uswa pike", vamwe vanofunga kuti chikara chinodya algae kubva mudura. Izvi hazvisi zvachose, zvinonyanya kudyiwa uye hwaro hwekudya kwahwo ihove. Haadye uswa kana algae zvachose, kunze kwekunge angomedza netsaona nehove inofamba ichimhanya.

Habitat uye maitiro ekuvhima

Iwe unogona kuwana chikara chine mazino mumatanho akawanda emvura yakachena. Ichakura nekuwanda mumadziva, madziva, nzizi. Madhamu zvakare inzvimbo yakanaka kune chikara, chinhu chikuru ndechekuti kune okisijeni yakakwana gore rese. Kana chinhu ichi chakakosha chisina kukwana, zvinokwanisika kuti munguva yechando pike pasi pechando inongodzipwa.

Anglers vane ruzivo vanoziva kwekutsvaga mugari ane mazino, nzvimbo dzaanofarira ndeidzi:

• tsiye;
• parwizi
• pasi makomba uye depressions;
• a drifter;
• hydraulic structures;
• masango emvura;
• zvinhu zvikuru zvakawira mumvura netsaona.

Iko pano kuti zino richamira rakavandira, richimirira kufamba kwehove duku. Zviri nyore kuziva nzvimbo yepike mune imwe nzvimbo isina kujairika; fry yemhando dzehove dzine rugare nguva nenguva dzinopararira munzira dzakasiyana kubva papike mumvura yakashama.

Kuvhima kunyanya munzvimbo dzekupaka kwayo, inova kuitira kuti ione zviri kuitika nekuseri kwenzvimbo yekutarisa. Kazhinji, vagari vakakuvadzwa vegomba vanova mhuka dzayo, asi kwete chete. Vanhu vakakura panguva ye post-spawning zhora uye mukudonha vanokwanisa kudya zvakapambwa chete 1/3 zvishoma pane ivo.

Pike, bream, sirivheri bream uye sopa vanenge vasingafarire pike nekuda kwechimiro chemuviri wavo, idzi mhando dzehove dzakatenderedza.

Zvinodyiwa nepike mudura zvakaonekwa, kudya kwayo kwakasiyana uye kunoshanduka muhupenyu hwese. Zvisinei, kubva pakuberekwa, iye chikara uye haambochinji mutemo uyu.
