Kuphulika kwa nyanja

Ichthyologists amaphunzira anthu okhala m'mitsinje ndi nyanja, koma musaiwale anthu okhala m'madzi amchere. Nthawi zambiri, nsomba zochokera kumadera osiyanasiyana amadzi zidzalumikizidwa ndi mayina wamba, ndipo ubale wawo sungakhalepo konse, udzakhala wa mabanja osiyanasiyana, ndipo nthawi zina ngakhale makalasi. Sea bream ndi imodzi mwa oimira owala kwambiri a madzi amchere a dziko lathu lapansi, omwe amadziwika ndi ambiri pansi pa dzina lakuti dorado. Kodi wokhalamo ndi chiyani komanso zomwe ali nazo tidzaphunzira limodzi.

Habitat

Dzina la nsomba zimadzilankhula lokha, zimakhala m'nyanja ndi m'nyanja, ndizofala m'madera otentha, otentha, madzi otentha padziko lonse lapansi. Anthu ambiri amatha kudzitamandira ndi madzi a m'mphepete mwa nyanja ya Turkey, Spain, Greece, Italy. Madzi a Pacific pafupi ndi zilumba za Japan alinso ndi anthu ambiri okhala ndi ichthy. Banja likuimiridwa ndi mitundu ya pelagic ya nyanja yotseguka. Kubala kumachitika m'madzi ofunda; chifukwa cha izi, kusamuka kwapachaka kwa anthu okhwima ogonana kumachitika.

Alembi aku Russia amathanso kuyesa mwayi wawo kuti agwire nsomba zamtundu uwu, chifukwa chake ndiyenera kupita kugombe la Murmansk la Nyanja ya Barents, kuchokera ku Kamchatka kupita ku Commander Islands kudzakhalanso kwabwino.

Nsomba za m'banjali ndizofunika kwambiri pamalonda, koma si mitundu yonse ya bream yomwe imagwidwa.

Maonekedwe

Zidzakhala zovuta kuzisokoneza ndi nsomba zina za m'nyanja ndi m'nyanja, zimakhala ndi machitidwe ndi machitidwe m'madzi. Zosiyana ndi:

• kukula kwa anthu, nthawi zambiri akuluakulu ndi apakati mpaka 60 cm utali amagwera mu ukonde wa trawlers;
• mitundu iwiri yokha imafika kulemera kwabwino ndi kutalika kochepa, Brama brama ndi Taractichthys longipinnis imatha kulemera kuposa 6 kg ndipo ilibe thupi loposa 1 mamita.

Apo ayi, maonekedwe a woimira m'madzi ali pafupifupi ofanana.

Mamba

Mwa oimira onse, ndi aakulu, pali ma spiny outgrowths ndi keels, omwe amawapangitsa kukhala prickly. mapira kwambiri amavulala, ndi zokwanira kunyamula woimira wogwidwa.

thupi

Zophwanyika m'mbali, zokhala ndi mawonedwe apamwamba. Zipsepsezo zimakonzedwa molingana, monga momwe zimakhalira m'madzi amchere.

Kutengera zaka, bream wamkulu amakhala ndi 36 mpaka 54 vertebrae.

mutu

Mutu ndi waukulu kukula, uli ndi maso akuluakulu ndi pakamwa, mamba ali pamtunda wonse. Chibwano cham'mwamba chimakhala chotakasuka kwambiri kuposa nsagwada zapansi, mamba amapezeka mochuluka.

Zipsepse

Kufotokozera kwa ziwalo zathupi izi kumawonetsedwa bwino mu mawonekedwe a tebulo:

Ndizofunikira kudziwa kuti dorsal ndi anal ndizofanana kwambiri pamitundu yonse.

Mawonekedwe

Ma Bream ochokera kunyanja ndi nyanja alibe chochita ndi cyprinids yamadzi amchere, ndi oimira banja losiyana komanso dongosolo. Dzinali linalandiridwa chifukwa cha kufanana kwina kwakunja. Mwalamulo, nsomba ndi za banja la Brahm la nsomba za m'nyanja za dongosolo la nsomba. Banja lili ndi mibadwo 7, yomwe ili ndi mitundu yopitilira 20. Gulu latsatanetsatane silingapweteke aliyense kuti adziwe.

Kugawidwa kwa sea bream kukhala genera ndi mitundu

Buku lililonse lokhala ndi zamoyo zam'madzi lidzakuuzani kuti bream yochokera kunyanja ndi nyanja ili ndi mabanja awiri, omwe amakhala ndi genera ndi mitundu. Mafani a ichthyofauna amawaphunzira mwatsatanetsatane ndipo tiyesetsa kuti tipeze.

Saltwater bream monga banja lagawidwa mu:

• Banja laling'ono la Braminae. Mwa anthu okhwima pakugonana, zipsepse za anal ndi dorsal zili m'mamba, chifukwa chake sizipinda, zipsepse zam'mimba zimakhala pansi pa mapiko a pectoral.

Aliyense wa oyimilira adzakhala ndi zonse zofanana ndi anthu ena, ndipo amasiyana ndi iwo. Dzina lakuti dorado ndi lodziwika bwino kwa okonda zakudya zambiri komanso okonda zakudya zam'nyanja, izi ndizomwe timapuma modabwitsa kuchokera pansi pa nyanja.

Tidazindikira mtundu wa nsomba zomwe zimatchedwa sea bream, komwe tingapiteko, tikudziwanso. Chatsala kusonkhanitsa zida ndi kupita kumupha nsomba.
