Pakati pa okhala kunyanja yakuya buluu imayimira nsomba zopangidwa ndi ray kuchokera ku dongosolo la ma perchiformes. Amadziwika kuti ndi nyama yolusa, yogwira nyama mwachangu. Pofunafuna, imadumphira kumtunda, ikutsetsereka kuti igwire nyama.
Koma iye amakhala chinthu ankakonda nsomba masewera. Kugonjetsa chilombo sikophweka - nsomba ili ndi mawonekedwe osimidwa, mwina ndichifukwa chake icefin yabuluu anakhala chinthu chamasewera amakono amakompyuta.
Kufotokozera ndi mawonekedwe
Mutha kuzindikira woimira banja labluefish ndi thupi lake lalitali komanso lathyathyathya, lokutidwa ndi masikelo ang'onoang'ono ozungulira. Kumbuyo kuli zipsepse ziwiri zokhala ndi cheza chonyezimira.
Sangalalani
Poyamba, mutha kuwerengera 7-8, ndipo chachiwiri mungapeze imodzi yokha, enawo ndi cartilaginous, soft. Mawiri awiri am'mapiko am'mbali ndi m'chiuno ndi achidule, mchira umafoloko.
Mtundu wakumbuyo ndi wakuda, wabuluu-wobiriwira, mbali zake ndi siliva wopepuka, ndipo pamimba pake pamayera. Zipsepse zam'mimba zimakhala ndi mdima. Mutu wawukulu wokhala ndi kamwa yayikulu. Nsagwada zokhala ndi mano akuthwa zimakankhidwira kutsogolo. Sangalalani pachithunzichi - mawonekedwe, wolusa weniweni, yemwe ali.
Nsomba zazikulu zimatha kutalika mpaka masentimita 130 ndikulemera mpaka 15 kg, koma mumalonda ogulitsa nthawi zambiri pamakhala masentimita 50-60 masentimita, olemera mpaka 5 kg.
Bluefish amakhala moyo paketi. Banja lalikulu la nsomba limaphatikizaponso anthu masauzande ambiri. Nthawi zonse kusamukira kusukulu, nyama zolusa zimabweretsa ngozi kwa anthu ena okhala mnyanja, koma zimakhala nyama yausodzi.
Masukulu a nsomba amasungidwa makamaka m'madzi am'madzi, akuya mamita 200. M'nyengo yotentha bluefish imasunthira kumadera a m'mphepete mwa nyanja, m'kamwa mwa mitsinje, koma imabwerera kunyanja ndikutentha kozizira.
Pakusaka, amawonetsa kuthengo komanso chidwi. Sukulu za nsomba zazing'ono sukulu yabuluu imaphwanyidwa ndikukhazikitsa mwachangu, kenako imawombera owazunzikira ndikupeza pakuponya. Ndi pakamwa lotseguka, mitsempha yotupa, imagwira nyama ndikuidya nthawi yomweyo. Mukamaliza kusaka, gulu la bluefishes limagwirizana mwachangu.
Mano obiriwira
Kwa munthu buluu osati owopsa. Mkati mwakuya, mukakumana ndi chosambira, nkhosazo zimathamangira kuthawa. Nsomba zokhazokha, zomwe zimatsutsa mwamphamvu, zitha kuwononga.
M'madamu omwe amapezeka
Asodzi ambiri amakhulupirira kuti bluefish ndi nsomba yomwe imapezeka mu Black Sea kokha, nthawi zina imapezeka m'madzi a Azov, Kerch Strait. Awa ndi malo okhalamo nyama zolusa, koma masukulu akulu abuluu amakhala m'madzi ozizira komanso otentha a Atlantic. M'nyanja ya Pacific ndi Indian, masukulu a nyama zolusa si zachilendo.
Madzi ofunda a Nyanja ya Mediterranean komanso gombe la Africa amakopeka ndikusuntha. Mothandizidwa ndi kutentha komanso kuthamanga kwamlengalenga, nyama zolusa zam'madzi zimatha kulowa pansi kwambiri, kukhala m'madzi ndikusambira pafupi ndi madzi.
Chakudya chamabuluu
Chakudya cha nyama zolusa m'madzi ndi nsomba zazing'ono komanso zapakatikati. Kuthamanga kwakusaka ndikokwera kwambiri kwakuti asayansi sanathe kudziwa kwa nthawi yayitali momwe mtundu wabuluu umagwirira ndikumeza nyama. Pochita izi, amalumpha pamadzi, amatseketsa wovulalayo pogwa. Makanema amakono okha, owonera pang'onopang'ono akuwulula zinsinsi zamakhalidwe ake.
Zowonera pamwamba pamadzi zikusonyeza komwe ma bluefishes akudya. Mofanana ndi nsomba zam'madzi zopanda nyama, nyama zolusa zimaukira limodzi kuti zigawane sukulu, kenako zimathamangitsa osungulumwa, kuwawononga mwachangu. Mbalame zouluka nthawi zambiri zimapatsa malo abwino kudya.
Nyanja Yakuda idyani
- anangula;
- nsomba yamchere yamahatchi;
- sardines;
- mullet;
- hering'i;
- athena;
- hamsa;
- sprats;
- ziphuphu;
- crustaceans, ngakhale nyongolotsi.
Kufulumira kwa kudya omwe adachitidwa nkhanzazi kunadzetsa mbiri yabodza yadyera yabluefish, yomwe imapha nsomba kuposa momwe imatha kudya. Amaganiziridwa kuti chilombo choluma nyamayo, koma zomwe zidalembedwazo zidatsutsa izi.
Kugwira abluefish
Mitembo yanyama yabuluu ndiyofunika kwambiri. Lili ndi mafuta okwana 3% komanso oposa 20% mapuloteni. Nyama yokoma yolimbitsa thupi imagawidwa ngati chakudya chokoma chomwe chitha kudyedwa mwatsopano.
Nsombazo zimathiranso mchere ndi kuumitsa. Kukoma kosakhwima kwa nyama zolusa panyanja kumadziwika ndi akatswiri a Western Atlantic, Brazil, Venezuela, Australia, USA, mayiko aku Africa. Mulibe mafupa ang'onoang'ono mu nyama.
Kugwira abluefish
Mamba ang'onoang'ono ndi osavuta kuyeretsa. Kukhutitsa nsomba ndi mavitamini, ma microelements kumapangitsa kukhala chinthu chothandiza. Msika waku Russia, nthawi zina mutha kupeza malonda obiriwira pansi pa dzina "nyanja zam'madzi".
Otsatira mbale za nsomba ayenera kukumbukira kuti pokonzekera mwatsopano muyenera kukhala osamala: pakati pa zipsepse zake pali singano zapoizoni zomwe zingayambitse ziwalo za ziwalo zikawonongeka.
Pakati pa zaka zapitazo, asodzi adagwira Nyanja Yakuda pamatoni mazana. Koma anthu akuchepa kwambiri kuyambira nthawi imeneyo. Nsombazo zimagwidwa mu maukondewo, koma nthawi zambiri amazigwira chifukwa cha chidwi.
Kugwira abluefish - chinthu chowedza masewera pogwiritsa ntchito ndodo yopota. Kuluma mwamphamvu kumachitika m'mawa kapena madzulo, pakusaka nyama yolusa. Chiwombankhanga chotheka chomwe chimagwidwa pa ndowe sichingathe kufikira mphamvu yake yomaliza, ndizovuta kwambiri kuchikoka m'madzi.
Nsombazi zimapanga majee osimidwa, zimalowa mwadzidzidzi kuzama kapena kudumpha m'madzi. Nkhondoyo imatha maola ambiri. Zimatengera luso lapamwamba, kudziwa zizolowezi za nsomba, kulimba mtima ndi kuleza mtima kuthana ndi kulimbana ndi chilombo.
Bluefish nthawi zina imakula
Nthawi zambiri mtundu wabuluu umakhala wopambana, womwe umatha kuthana ndi mbedza chifukwa chonyenga. Akatswiri odziwa kuwombera amayesa kugwira nsomba nthawi yomweyo. Khola likakhazikika pakamwa, sungani mabuleki ndikukoka chilombocho.
Pofuna kusodza, ndodo yozungulira yopota ndiyabwino, yokhala ndi chokulungira chopanda kanthu komanso mzere wa 0,4-0.5 mm m'mimba mwake. Mwa omwe alibe chidziwitso mungasankhe "Dolphin". Msuzi umafunikira mawonekedwe otambalala, wokhala ndi gawo la concave. Ufa umathiridwa ndi malata osungunula. Msuzi wolemera umakopa nsomba kwambiri, ndipo zolemera sizifunikira.
Mphepete mwa nyanja, ma buluu amawoneka kawirikawiri, pokhapokha mkuntho utawomba, nthawi zambiri amapezeka mumabwato oyendetsa galimoto. N'zovuta kulingalira m'nyanja momwe nsomba zimakhalira. Kusodza mwachisawawa kumakopa nyama zomwe zimakonda kukhala zokha.
Mphukira zimatulutsa madzi, phokoso la mbalame zomwe zimakopeka ndi phwando la nsomba. Mwayi wosodza bwino umakweza nyambo za mackerel, anchovy, garfish ngati mutasuntha bwato mita 70-90. Usodzi umapitilira kuyambira nthawi yachilimwe mpaka kumapeto kwa nthawi yophukira, pomwe masukulu a nsomba zazing'ono pafupi ndi gombe.
Kubereka ndi kutalika kwa moyo
Kukula kwa bluefish kumayamba zaka 2-4. Nyamayi imangobwera m'madzi otenthedwa bwino, kuyambira koyambirira kwa Juni mpaka kumapeto kwa Ogasiti. Akazi amatulutsa mazira oyandama m'nyanja, m'magawo angapo.
Kubereketsa kwakukulu kumathandiza kuti anthu asatheretu, chifukwa nsomba zina zimadya caviar, ndipo zambiri zimangofa. Zazikazi zazikulu zimaikira mazana masauzande, mpaka mazira 1 miliyoni, omwe, ngati apulumuka, mbozi zoyandama zimaswa m'masiku awiri.
Ndi ochepa kukula, ofanana ndi zooplankton. Mphutsi zimanyamulidwa patali ndi pano. Ndizovuta kwambiri kuti asayansi aphunzire njira zonse zoberekera.
Pazakudya za achinyamata, chindapusa cha crustacean, zopanda mafupa. Thupi la mwachangu likakula mpaka masentimita 8-11, kusintha kwa zakudya - chowombetsa nyama chimadzuka. Nsomba zimakhala chakudya chachikulu. Anthu amtundu wa Bluefish amasintha kwambiri nthawi ndi nthawi: pali nthawi zakutha, zomwe zimasinthasintha ndi magawo azambiri.
