thupi nsomba ali ndi mamba ka mawonekedwe cylindrical. N'zochititsa chidwi mtundu. Amur Pike, malingana ndi malo ndi zaka, ali mithunzi osiyana a mtundu chitsanzo mamba m'thupi. Zimakhala golide, siliva, Kamaoneka. Pa nsana ndi mdima mosintha thupi lonse - osiyana mdima mawanga, zofiirira ndi wakuda, apo iwo ali pa dorsal ndi zipsepse caudal. Iwo akulondola oblique yopingasa mizere, aliyense ndi 25-35 mawanga.

Wachinyamata (pansi 35 cm) m'malo mawanga - Mzere yopapatiza. Izi masking wa madzi osaya pamene gawo la zomera. Schuchata mpaka kufika zisanu centimeter yaitali, iwo kudya zooplankton. Mukatero yambani kusaka kwa nsomba yaing'ono. The zakudya wamkulu zikuphatikizapo pafupifupi onse nsomba katundu wa madzi: rudd, gudgeon, carp, smelt, nase ndi ena. Monga chakudya suti ndi Chule, ndi makoswe ang'ono.

kubalana

nsomba msinkhu chifikira zaka 3-4, pakadali pano, m'litali ndi 40 cm. nthawi Spawning zimadalira nthawi chigumula zomera lapansi. Madzi osefukira pa Amur Mtsinje ndi nsonga zitatu - kasupe, chilimwe ndi autumn. Spring amatanthauza zonse kwambiri pa nthawi, koma zaka zina zikhoza kukhala kosangalatsa zogwirika mu nthawi.

Spawning umayamba mwamsanga kumasulidwa kwa mitsinje ya ayezi - kuyambira chiyambi cha April, ndipo nthawi zina mpaka m'ma June (malingana ndi kutentha madzi), monga kutentha pa spawning amakwiya chiwonongeko cha mazira. Amur kapena kambuku Pike defers mazira 25 000 150 000. The apakatikati - 45 000 zidutswa. Mazirawa ndi lalikulu - mpaka 3.5 mm m'mimba mwake, chikasu. Gilateni adzatsekeredwa kamadziphatika mazira kuti zomera wandiweyani mu zone ya m'mphepete mwa nyanja.

Patangotha masiku 10-12 mphutsi zitangomera, mpaka 8 mm, ndi yolk sac. Schuryat chitukuko ndi kudya:

• kuti June - 5 cm;
• mu July - masentimita 14;
