Pollock amamveka ndi ambiri, ndipo kukoma kwake kumadziwika kuyambira ali mwana. Ndi kanyama kake kamene kamagwiritsidwa ntchito mu McDonald's yotchuka ngati timitengo ta nsomba, buledi komanso gawo la mbale zina za nsomba.
Kufotokozera kwa Pollock
Ngati mumva za pollock ku USA, mwina sitikulankhula za wojambula wotchuka, koma za nsomba za pollock... Atlantic pollock ili ndi michere yambiri. Nsomba iyi timakondedwa ndi ambiri a ife chifukwa cha nyama yake yoyera, yofewa, yomwe ndiyabwino kugwiritsa ntchito m'njira yopyapyala. Pollock ndi nsomba yopanda mafupa yomwe imakwanira bwino pazakudya.
Kukoma kwake ndi mawonekedwe, nsomba, kukumbukira nyama ya nkhanu. Ichi ndichifukwa chake tizilomboti timagwiritsidwa ntchito popanga timitengo ta nkhanu ndi zinthu zina za nsomba, zomwe zimapangitsa kuti zotsalazo zikhale zotsika mtengo. Komanso, zambiri kwa okonda nsomba zokhwasula-khwasula za mowa: nsomba za amber ndi tsabola ndichopangidwa kuchokera ku nyama ya pollock.
Ndizosangalatsa!Nsomba za Pollock ndi za banja la cod ndipo ndizofunikira kwambiri pamalonda. Zambiri mwa nsombazi zimapezeka kumpoto kwa Atlantic. Nsomba zomwezo zimakula ndikukula kwakukulu (mpaka mita imodzi).
Pali mitundu ingapo ya pollock - Atlantic, European ndi ena. Pafupifupi theka la nsomba zapachaka zapadziko lonse lapansi zimachokera ku England ndi Europe. Zina zonse zimagwidwa ndi nsomba za Russian Federation. Nsomba ya Alaska pollock ku Bering Sea ndiye nsomba yayikulu kwambiri padziko lonse lapansi.
Maonekedwe
Alaska pollock ili ndi mtundu wamtambo wolumikizana womwe umafanana ndi chilichonse, womwe umatsikira kumutu mpaka mchira. Thupi lonse la nsomba limakutidwa ndi silvery, mamba ang'onoang'ono, amada pang'ono pamwamba pake. Masikelo otsalawo amaphimbidwa ndi mawanga akuda kwambiri, osanjikiza pamwamba pa thupi ndi mutu.
Pollock ali ndi zipsepse zitatu zakuthambo ndi zipsepse ziwiri zamkati, zolekanitsidwa ndi mpata wopapatiza. Kumbuyo kwa nsombayo kuli zipsepse zitatu zosiyana, yoyamba ili pamutu. Chachikulu kwambiri komanso chachitali kwambiri ndi chachiwiri motsatira. Palinso zipsepse za m'chiuno. Mzere wotsatira wa thupi wokhala ndi zopindika. Mutu wa nsombayo umawoneka wosafanana ndi thupi, chifukwa ndiwowoneka wokulirapo. Zomwezo zimagwiranso ntchito ndi maso a nyama. Chowonadi ndi chakuti pollock ndi woimira nyanja yakuya ya ichthyofauna. Mbali yapadera ya nsombayi ndi ndevu yaying'ono yomwe ili pansi pa mlomo wakumunsi. Nsagwada zimayenda patsogolo kwambiri.
Maganizo okhudzana ndi kukula kwa nsomba za pollock ndizovuta. Ena amati kulemera kwa nyama yayikulu kwambiri ndi makilogalamu 3 900 magalamu okhala ndi kutalika kwa thupi kwakukula masentimita 90. Zina zimatsimikizira kukhalapo kwa masentimita 75 a anthu olemera ma kilogalamu asanu. Kaya zikhale zotani, anthu wamba amawerengedwa kuti ndi anthu olemera pafupifupi kilogalamu imodzi ndi theka ndi kutalika kwa thupi kuyambira masentimita makumi anayi mpaka 75.
Khalidwe ndi moyo
Nsombazi, ngakhale ndizakuya, zimamva bwino m'mbali yamadzi komanso pansi pake. Kuzama komwe amakonda kwambiri pollock ndi 200 mita.
Ngakhale mutha kuwapeza akuya mita 700, pomwe akumva bwino. Nsombazi zimakonda madzi ozizira. Kutentha kokwanira kwa malo okhala pollock kumatengedwa ngati 2-9 madigiri Celsius. Pollock ndi nsomba zamasukulu ochezeka.
Ndizosangalatsa!Pollock ndi pelagic, nsomba zomwe zikukula mofulumira. Ikukula, imamtambasulira m'litali kwambiri, kwinaku ikukula. Mnyamata wina wazaka makumi awiri wamwamuna wazaka chimodzi "wachinyamata" mchaka chachinayi cha moyo adzakhala nsomba yokhwima pogonana, masentimita makumi atatu.
Amadziwika ndi kusunthika kwatsiku ndi tsiku. Ndiye kuti, usiku, anthu okhala m'madzi amatha kukwera pamwamba pamadzi kapena kusambira mozama kwambiri. Komabe, pakayamba tsikulo, nsombazo zimapitabe mpaka 200 kapena, nthawi zina, mamita 500-700. Pokhapokha panthawi yomwe amatulutsa nyama, pollock amabwera pafupi ndi gombe ndipo amakhala pamtunda wa 50 mpaka 100 mita kuchokera pamwamba. Pachifukwa ichi, nsomba zowonjezereka zimapangidwa.
Kodi pollock amakhala nthawi yayitali bwanji
Nsomba za Pollock zitha kukhala zaka khumi ndi zisanu.
Malo okhala, malo okhala
Mitundu yonse iwiri ya pollock imapezeka ku North Atlantic. Zitha kuwoneka kumadzulo kwa North Atlantic, kuchokera ku Hudson Strait kupita ku Cape Hatteras ku North Carolina, komanso kum'mawa kwa North Atlantic kuchokera ku Spitsbergen kupita ku Bay of Biscay.
Nsombazi zimapezekanso mu Nyanja ya Barents komanso ku Iceland. Nsomba za Pollock zimapezekabe kumpoto chakum'mawa kwa Atlantic kunyanja ya Norway, kuzilumba za Faroe ndi Iceland mpaka ku Bay of Biscay, komanso England ndi Ireland.
Zakudya za Pollock
Nsomba za Pollock ndizofunikira kulumikizana kwachilengedwe pagulu lazakudya ku North Atlantic chifukwa chakudyera. Amawononga mitundu ingapo yazamoyo zazing'ono zam'madzi, monga nkhono (squid) ndi nkhanu (makamaka krill), ndipo samadya nsombazi kapena nsomba zina zazikulu pamadongosolo osiyanasiyana m'mbiri ya moyo wawo. Nthawi yomweyo, achinyamata amadya plankton, amphipods, krill, ndi nematode.
Komanso ma annelids ndi crustaceans (krill, shrimp, nkhanu). Pakukula, munthu yemwe akukula sakusangalalanso ndi chakudya chochepa, ndipo nsomba imasamukira kuchakudya chopatsa thanzi, chachikulire. Kudya anthu wamba kumadziwika kwambiri pakati pa pollock. Iwo, opanda mapasa a chikumbumtima, amatha kudya zamtundu wina aliyense, ndi caviar yawo komanso mwachangu.
Kubereka ndi ana
Pollock nthawi zambiri amabala kumapeto kwa nthawi yozizira komanso koyambirira kwa masika kum'mwera chakum'mawa kwa Bering Sea... Anthu azaka za 3-4 amatha msinkhu wogonana.
Pofika nthawi imeneyi, kulemera kwa nsombayo kumafika pachimake. Kutengera dera lokhalamo, misa ndiyoyambira 2.5 mpaka 5 kilogalamu. Munthu m'modzi amatha kubala pafupifupi nthawi khumi ndi zisanu m'moyo wake wonse.
Ndizosangalatsa!Mazira omwe amatulutsidwa m'thupi la mkazi amayendayenda m'mbali yamadzi. Malo awo kufika akuya mamita makumi asanu.
Kubzala kokha kumatha kuchitika munthawi zosiyanasiyana pachaka. Anthu okhala munyanja ya Bering amasankha izi masika ndi chilimwe. Pacific nsomba - yozizira ndi masika. Kamchatka pollock imangobereka masika okha. Nsombazi sizimatsekerezedwa ngakhale ndi kuzizira kwamadzi otentha kwambiri. Ngakhale pa -2, amabereka bwino mazira a ana amtsogolo. Chinsinsi chake chimakhala m'madzi amchere komanso momwe nsomba zimakhalira. Monga mukudziwa, madzi amchere amaundana kutentha pang'ono, ndipo antifreeze wachilengedwe amayenda m'mitsempha ya pollock.
Adani achilengedwe
Popeza nsomba yotchedwa pollock imakhala yakuya kwambiri, ilibe adani ambiri omwe angabweretse ngozi. Mwachidziwitso, awa akhoza kukhala squids akulu kapena mitundu ina ya nsomba za angler. Koma palibe umboni wowerengeka wonena za kuwukira kwa izi kapena zolusa zija. Musaiwale kuti Alaska pollock amakhala pachiwopsezo makamaka panthawi yopanga, pomwe masukulu a nsomba amayandikira pamwamba pamadzi, omwe amapezeka kufupi ndi gombe.
Chiwerengero cha anthu komanso mtundu wa mitunduyi
Chifukwa cha kusodzedwa kwa nsombazi, anthu awo akuopsezedwa kuti atha.... Mu 2009, Green Peace Association idawonetsa nkhawa yake, kuyambira kugwa kwa chaka chomwecho, idalimbikitsa anthu kuti asiye kugula ndikudya nsomba iyi m'maiko onse adziko lapansi.
Zidzakhalanso zosangalatsa:
- Saika
- Pike
- Tench
- Kumvi
Koma polingalira za mtengo wotsika wa nsomba, phindu lake la chakudya ndi kukoma kwake, komanso mwayi wogwira, izi sizingatheke mpaka lero.
Mtengo wamalonda
Nsomba za Pollock zimagwidwa kuchokera kunyanja pamalonda. Lero, nsomba zam'madzi zam'madzi izi zimakhala zoyambirira padziko lonse lapansi.
Ndizosangalatsa!Kale mu Mipingo, dziko nsomba anali mpaka matani miliyoni asanu ndi awiri.
Pofika kumayambiriro kwa zaka chikwi chachitatu, zizindikirizo zidatsika mpaka matani 2.5-3, 1.6 omwe adagwidwa ndi Russian Federation. Osangokhala zakudya zopatsa thanzi, zowonda komanso zokoma, komanso chiwindi chake ndichopindulitsa kwambiri.
