Namuhla sizokhuluma ngakho pike izinhlanzi. Le nhlanzi inegama le-pike ngoba lelo igama lesikhali sasePoland esifana nalo. Inamanye amagama ajwayelekile njenge-pike enkulu yasenyakatho, i-pike yotshani, inhlanzi yengwenya (lokhu kungenxa yokuthi ikhanda layo liyafana nelengwenya). Igama layo lesayensi ngu esox lucius futhi inelukuluku elithile.
Kulesi sihloko sizokhuluma ngokujulile ngenhlanzi ye-pike, ngakho-ke uma ufuna ukwazi konke ngakho, kufanele uqhubeke ufunde 🙂
Izici eziyinhloko
Le nhlanzi ingeyehlobo lohlobo lwama-Exos. Lezi zinhlanzi zihlala emanzini anosawoti namanzi ahlanzekile. Bayakwazi ukuhlala kuzo zombili izindawo. Umbala wayo unombala oluhlaza okomnqumo futhi unezinhlamvu ezithile ezinombala ophuzi nokumhlophe esiswini. Ibuye ibe nezindawo ezimfushane nezikhanyayo ezimise okwebha endaweni eseceleni. Ezinye zazo zinamabala amnyama engxenyeni yamaphiko.
Ukubona ipiki encane kufanele sibheke imivimbo ephuzi enayo emzimbeni wayo. Ilukuluku leli nhlanzi elinalo ukuthi engxenyeni engezansi yemiphunga yalo iyeka ukuba nezikali. Futhi, uma ubhekisisa lelo khanda elifana nengwenya, singabona izimbotshana zezinzwa. La ma-pores asatshalaliswa ekhanda lonke, ikakhulukazi engxenyeni engezansi yomhlathi ukuqonda kangcono imvelo okuyo ngaso sonke isikhathi.
Kunezinhlobo ezithile ze-hybrid zezinhlanzi ze-pike ezifana ne- Ingwe ye-Esox musquin. Kulolu hlobo lwezinhlobo, ubulili besifanekiso ngasinye bunomehluko omkhulu kolunye. Abesilisa abayinyumba futhi abakwazi ukuqhubeka nokuzala, ngakho-ke bayizinhlobo zesizukulwane esisodwa. Kodwa-ke, kwezinye izikhathi insikazi ivundile futhi ingawela nezinhlobo ezithile zabazali.
Singahlangana futhi nezinhlanzi ze-pike zesiliva. Akuwona ama-subspecies noma yini efana naleyo, kepha kunjalo ushintsho olwenzeka kubantu abahlakazeke kakhulu.
Ukuziphatha kwenhlanzi ye-pike
Lezi zinhlanzi ziyakwazi ukwakha ukunyakaza ukuze ziqale ukubhukuda ngokushesha okukhulu. Lokhu kushesha okukhulu kubangela ukuqhuma okuncane kokubhukuda okwenza inyamazane yabo yesabe ukunyakaza kwabo okungalindelekile.
Abasebenzisi nje kuphela lesi siqalo esihle ukuzingela, kepha ukugwema ukuzibandakanya ezimeni ezisongela impilo. Bangaba nokuphila kokuhlala phansi, kepha lapho bethola inyamazane yabo, Basebenzisa ukuqhuma ukuqalisa nokubabamba ngaphandle kwenkinga enkulu.
Ngesikhathi sokunyakaza okusetshenziswa yizinhlanzi ezinama-pike ukuzingela, yenza ezinye zimi ngendlela eyi-S. Lokhu kwenziwa ukuze zikwazi ukubhukuda ngejubane eliphezulu. Uma ufuna ukwehlisa ijubane, kufanele benze ukubhukuda okwenziwe ngo-C okubasiza ukuba behlise ijubane ngokubonakalayo.
Lokhu kuqhuma kuyingxenye yokuziphatha kwabo ngenxa yokuthi lezi zilwane zinokugaya okushesha kakhulu. Ngokungadingi ukusebenzisa amandla ekugayeni okude kangako, alula impela futhi angathola lokhu kuqhuma kwejubane okucishe kube khona. Yile ndlela abathola ngayo inani elikhulu kakhulu lezisulu ngosuku. Ngokungafani nesikhathi sasemini bayasebenza ngokwengeziwe, ebusuku bahlala bezolile futhi baphumula isikhathi esiningi.
Indawo nendawo okusatshalaliswa kuyo
Lezi zinhlanzi zitholakala ezindaweni zemvelo ezakhiwe yimifula yamanzi engajulile futhi ehamba kancane. Kumele kucatshangwe ukuthi, ukuze izinhlanzi zepike zikwazi ukuqhuma, ijubane lamanzi alikwazi ukuba likhulu kakhulu noma kungaba ukumelana okukhulu ukunqoba. Ungazithola futhi ezindaweni lapho kunokhula emachibini, emanzini abandayo, acwebile futhi anamadwala. Ngakho-ke igama layo liyi-pike yotshani.
Ngokuvamile, bayizilwane ezisebenzisa ukuqamekela njengesisetshenziswa esihlaselayo. Zihlala phansi futhi zicashe phakathi kwamatshe ukuze zihlasele inyamazane yazo ngokuqhuma ngesikhathi esingcono kakhulu. Bayakwazi ukugcina amandla abo futhi bahlale bethule kahle isikhathi eside ukuze abaqamekeli babo babe ngcono kakhulu. Lokhu kuqinisekisa ukuthi ayinacala lapho kuziwa ekubambeni inyamazane yayo nokudla kwayo.
Bangatholakala kunoma iyiphi indawo yokuhlala leyo ube nomzimba wamanzi futhi ube nokudla okuningi kubo. Zidinga izindawo ezifanele zokuzalela, njengoba kuyinto ebalulekile ekukhiqizeni kwazo.
Zivame ukubonwa ngokuziphatha kokudla, ngakho-ke izinhlanzi ezi-pike zidinga izindawo lapho zingaphephela khona phakathi kwezitshalo ukuze zingadliwa yizinhlobo zazo. Zihlala kakhulu emanzini amasha kune-brackish, kungabonakala kuphela emanzini oLwandle iBaltic. Kwezinye izindawo ihlala emanzini ahlanzekile.
Uma amanzi enamafu amancane, aba ngcono. Lokhu kuhlobene nokuncika kwalezi zinhlanzi ebukhoneni bohlaza ukuze zicashe kwabanye. Zimbalwa izitshalo ezikhula emanzini abhidlikile ngenxa yokuntuleka kwemisinga yokukhanya enamandla namandla, ngakho-ke bazoba nenkinga yokuzifihlela okwabo nokuzingela.
Ukuzala
Lezi zinhlanzi zikhetha isikhathi sentwasahlobo ukuba zizale. Lokhu kungaba ngenxa yezizathu eziningi. Kungenxa yokuthi ngalesi sikhathi sonyaka banezisulu eziningi zokudla noma inyamazane yabo idlula ngesikhathi sokufuduka. Kungenzeka futhi ngenxa yokongiwa kwamandla angcono ngenxa yamazinga okushisa amanzi afudumele.
Inhlanzi ye-pike iyakwazi ukufinyelela ukukhula kwabo ngokobulili nokuzala kusukela eminyakeni emibili ubudala. Izala ngesikhathi sentwasahlobo lapho izinga lokushisa lamanzi lifinyelela cishe kuma-degree ayisishiyagalolunye.
Abesifazane bayakwazi ukubeka amaqanda amaningi kakhulu. Lokhu kungenxa yokuthi baqinisekisa impumelelo yokuzala ngoba ngaphezu kwengxenye yamaqanda ngeke ifinyelele ebudaleni. Uma amaqanda esekhishwe ngabesifazane, uma izinga lokushisa lamanzi lingaphansi kwamadigri ayisithupha, ngeke achamuke. Mhlawumbe lokhu kuchaza ukuthi kungani zizala entwasahlobo.
Ngiyethemba ukuthi ngalolu lwazi ungazi kangcono izinhlanzi zepike.
