Akusizi ngalutho abakushoyo ngabadobi - banentshisekelo, ngoba bakulungele ukudoba nganoma yisiphi isikhathi sonyaka noma sosuku. Kunezinhlanzi eziningi emifuleni nasemachibini ethu. Ihlukile hhayi ekubukeni kwezinhlanzi, ukunambitheka, kepha, kunjalo, ngendlela yokubamba. Enye yezindebe zokudoba ezithandwa kakhulu pike izinhlanzi.
Ukubukeka kwepike nendawo yokuhlala
Ungowomndeni wepike. Izinhlanzi zomfula iPike esidla inyama, emizimbeni yethu yamanzi amasha kubhekwa njengenye yezinkulu kakhulu. Ephakathi usayizi pike kuze kufike kumitha elilodwa kuya ku-5 kg. Kepha abantu baqoshiwe abafinyelela kumamitha ayi-1.5 ngosayizi futhi bafinyelela kuma-35 kg. Umzimba wayo umise okwe-torpedo, ikhanda layo likhulu ngomlomo obanzi. Umhlathi onemigqa engezansi yamazinyo uphumela phambili kancane.
Pike amazinyo icijile kakhulu, kuningi kwayo, emigqeni eminingana, futhi akutholakali emihlathini kuphela, kodwa nasolwangeni, olimini nasezinsikeni. Imihlathi ihlelwe ukuze kuthi lapho kubanjwa inyamazane, amazinyo angene kulwelwesi lomlomo, kepha uma isisulu sizama ukubaleka, bayasukuma bayibambe.
Emhlathini ongezansi amazinyo angashintshwa - amadala ngamasha. Ngaphezu kwalokho, zonke zikhula ngasikhathi sinye, amazinyo afaka nje okunye asezicubu ezithambile ezingemva kwezinyo elibambile. Lapho iwa, amazinyo "asele" asuswa endaweni yawo futhi athatha indawo yamahhala.
Umbala wepike ungahlukahluka, kuya ngemvelo. Umbala oyinhloko wezikali ezincane ze-pike mpunga, futhi amabala emzimbeni angahluka, kusuka ophuzi kuya konsundu. Ingemuva lihlala limnyama, amabala ezinhlangothini akha imivimbo emzimbeni wonke. Abantu abadala banombala omnyama omnyama.
Izinhlanzi ezihlala emanzini anodaka amachibi anosilika nazo zibukeka zimnyama kunezinye. Amaphiko amabili abhangiliwe awolintshi futhi kaningi abomvu kakhulu, ansundu angabhangqiwe noma ompunga. Umbala wabo bobabili ubulili uyefana, owesifazane angahlukaniswa kowesilisa ngosayizi wawo omkhulu nedivayisi ehlukile yohlelo lwe-genitourinary.
IPike itholakala endaweni epholile nasenyakatho. Amanzi ahlanzekile e-Eurasia naseNyakatho Melika yizindawo zawo zokuhlala. Kutholakala nasezingxenyeni zolwandle ezinamanzi, ngokwesibonelo, emachwebeni olwandle lwaseBaltic nase-Azov, naseLwandle Olumnyama, i-Aral kanye neCaspian.
Engxenyeni esenyakatho kunezinhlobo ezihlukile - i-Amur pike, ehlala eMfuleni i-Amur wegama elifanayo. IHabitat enyakatho ukusuka eKola Peninsula kuya e-Anadyr. Esikhathini esiningi igcina isendaweni engasogwini, emahlathini, emahlathini, ezinkingeni, lapho kungekho khona amandla asheshayo. Ihlala nasemachibini nasemifuleni egeleza imifula.
Ipiki ayitholakali emanzini amabi, njengasemachibini amancane amile. Ipiki idinga umoya-mpilo omningi, ngakho-ke abakwazi ukusinda ebusika echibini elincane. Esikhathini esiningi, ngisho noma befika lapho ngesikhathi sezikhukhula zomfula, uqweqwe lwasebusika luyawenza umsebenzi wawo - amapiki akulezi zindawo zokugcina amanzi ayafa, kanye nezinye izinhlanzi.
Ukuvimbela lokhu ukuthi kwenzeke, abadobi uqobo bazama ukunakekela izinhlanzi - bagqobhoza izimbobo ezinkulu eqhweni, abazimboza ngamagatsha bese bezifafaza ngeqhwa ukuze amanzi akuyo angaqedi isikhathi eside, futhi umoya-mpilo ungangena echibini.
Indlela yokuphila yePike
Emini, ipiki ivame ukuhlala duze nolwandle, ezihlahleni zamanzi. Izama ukusondela ezintweni ezinkulu ezingafihlwa kalula ngemuva, futhi ngasikhathi sinye, ukuze ukudla kungabi kude kakhulu. Abantu abancane bazama ukunamathela emhlangeni nakolunye ulwelwe, lapho kuhlala khona izinhlanzi ezincane, ezilungele ukudla.
Abantu abakhulu bahlala ekujuleni, kodwa futhi bazama ukuthola indawo yokukhosela ngesimo se-driftwood noma isihlahla esigcwele amanzi. Amapiki ayayithanda imisebe yelanga efudumele, futhi ngezinsuku ezicacile ayabhukuda aze afike ogwini impela, abeke umhlane wawo omnyama futhi abambe anganyakazi isikhathi eside. Izinhlanzi ezinkulu azimi eduze nogu, kodwa futhi zintanta zibuyele ngaphezulu, zibambelele ezihlahleni zotshani.
Uma ziphazamisekile, zitshuza ngokukhulu ukushesha, kepha noma kunjalo zizama ukuhlala ziseduze "nolwandle" lwazo. Ngendlela, e ukudoba i-pike, kulula kakhulu ukuyibamba izungeza emanzini acwebile, ngakho-ke udinga ukuzama ukuyikhipha otshanini. Emizimbeni ehlukene yamanzi, indlela yokuphila yamaphayiphi ahlala kuyo yehluke kancane, kodwa noma kunjalo, okokuqala pike Ngumphangi nomzingeli.
Ukudla kwepike
Cishe kusukela ebuntwaneni, amapiki anambitha ukudla kwezilwane. Ngisho nefry, okudla kwayo kusekelwe ku-zooplankton, zama ukuzingela izibungu zezinhlanzi ezincane ezahlukahlukene, yize okwamanje zingu-1.5 cm ubude kuphela. Njengoba ikhula kuze kufike ku-5 cm, ama-pikes ashintshela ngokuphelele ekudleni kwezinhlanzi. Ngenkathi yasebusika, umsebenzi we-pike wehla kakhulu, lokhu kusebenza nasekudlaleni.
Kepha uhlala ezingela ngendlela efanayo - ecashe esikhotheni noma otshanini, uphuthuma ngokushesha isisulu esibhukuda. I-pike igwinya ikhanda lezinhlanzi kuqala. Uma ukwazi ukuyibamba unqamule umzimba, umhlaseli uzophendula izinhlanzi ukuze zigwinyeke kalula. Kuleli qophelo, amazinyo okuxubha aphenduka ngendlela yokuthi inhlanzi ihambe iye kupharynx ngaphandle kokuphazamiseka.
Uma inyamazane izama ukubaleka, amazinyo abukhali ayophumula nayo ngamathiphu bese isisulu sibe nendlela eyodwa kuphela - esiswini sikaphiki. Ngesikhathi sokuzingela, i-pike isebenzisa kokubili umbono nesitho esibucayi - umugqa we-lateral, othuthukiswa hhayi kuphela kulo lonke ubude bomzimba, kodwa nasekhanda.
KU-IN pike yokudla zingakhethi kakhulu, zingadla konke ezingakubamba futhi zingene emphinjeni. Lezi izinhlanzi ezingama-goby, i-whitefish, i-bream, i-perch, i-roach, i-crucian carp, i-ruff, i-gudgeon, i-minnow kanye namapiki amancane ngokwabo. Kaningi, zidla abafo, uma ziningi echibini futhi zincane ngosayizi.
Zidla namaxoxo, amatshwele, amadada, ama-waders, ama-crustaceans e-molting nezilwane ezincane (hares, amagundane, izingwejeje) ezibanjwe emanzini. Emachibini asezintabeni eCanada, lapho kutholakala kuphela amaphikishi, abantu abadala badla inzalo yabo. Uma sikhuluma ngezifiso zepiki, kuyaziwa ukuthi igwinya kalula ukudla, okwenza i-50-65% yesisindo sayo nosayizi wayo.
Ukukhiqizwa kabusha nokulindelwa kwempilo kwepiki
Inhlanzi izala ekuqaleni kwentwasahlobo, lapho iqhwa selincibilika. IPike caviar ibeka ulwelwe ekujuleni kwamamitha angu-0.5-1. Insikazi izalela amaqanda, kuthi abesilisa bayiphelezele bese beyayifaka ngobisi. Umuntu oyedwa angazala amaqanda ayizinkulungwane ezingama-20-200. I-caviar igxile otshanini, ulwelwe, bese iwela phansi futhi zingakapheli izinsuku eziyi-8 kuya kweziyi-14 gazinga. Ama-pikes avuthwa ngokocansi eneminyaka engu-2-4.
