ʻIke pono e pili ana i ka lawaiʻa kūʻai
Ma Rusia, ʻelua ʻano ʻano: ʻEulopa a me Siberian vendace. No ka ʻohana iʻa keʻokeʻo. ʻO European vendace he loko a me ka loko-waiwai ke ʻano o ka iʻa keʻokeʻo, ʻo Siberian kahi ʻano muliwai. ʻO ʻEulopa, ma ke ʻano he kānāwai, hoʻokumu i nā ʻano noho, Siberian - momona i ke kai. Ma nā kūʻai kūʻai ʻEulopa, ʻo ka ʻokoʻa nui o waho i manaʻo ʻia he mau unahi paʻakikī, e hāʻule maʻalahi. Hiki i ʻEulopa ke hana i nā ʻano dwarf a, ma ke ʻano nui, ʻoi aku ka liʻiliʻi (Onega ripus a hiki i 1 kg); ʻO nā mea kūʻai Siberian hiki i ke kaumaha o 1.3 kg. He paʻakikī ke ʻike ʻana i ke ʻano o nā subspecies, a aia nā ʻokoʻa morphological āpau.
Nā ala e hopu ai i nā mea kūʻai
Loaʻa ʻia ʻo Vendace ma luna o ka lana, ka mea lalo, a me ka hoʻoilo a me ke kauwela jigging a me ka lure kūpaʻa.
Ka hopu ʻana i nā mea kūʻai aku ma nā mea lana
Loaʻa ka iʻa ma kahi mamao loa mai ke kahakai a ma kahi hohonu. Noho ka iʻa ma nā papa haʻahaʻa o ka wai. No ka lawaiʻa, hiki iā ʻoe ke hoʻohana i ka lana a me ka "holo holo". No ka lawaiʻa, kūpono nā koʻokoʻo me kahi "holo holo". ʻAʻole i manaʻo ʻia ka iʻa he hilahila loa, akā ʻaʻole ʻōlelo ʻia nā mea hana koʻikoʻi.
ʻO ka hopu ʻana i nā mea kūʻai aku me nā mea hoʻoilo
ʻO ka lawaiʻa lawaiʻa kaulana loa ʻo ia ka lawaiʻa hau hoʻoilo. No kēia mea, hoʻohana ʻia nā koʻokoʻo kūnou. E hoʻohana i ka mormyshki a i ʻole nā lou me kahi nozzle. Pono ka hānai ʻana. No kēia, hiki ke lawelawe i ka ʻiʻo ʻokiʻoki o nā mollusks, bloodworms, worms a pēlā aku.
ʻO ka hopu ʻana i nā mea kūʻai aku ma mormyshka i ke kauwela
No ka lawaiʻa ʻana me ke kuʻi ʻana, hoʻohana ʻia nā koʻokoʻo lele i hoʻolako ʻia me nā nod kūikawā. No ka lawaiʻa, kūpono nā mormyshkas hoʻoilo maʻamau: he pellet, he ant, a he kulu. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i nā hiʻohiʻona ʻeleʻele. Koho ʻia nā nods a me ke kaumaha o nā mormyshkas e like me nā kūlana lawaiʻa.
Maunu
ʻO ka maunu he ʻāpana ʻiʻo mollusk, invertebrate larvae, me nā ʻano koko, nā ilo, nā ʻāpana iʻa. I ka lawaiʻa ʻana me nā baubles, ʻōlelo ʻia hoʻi e kanu i nā ʻāpana ʻiʻo.
Nā wahi lawaiʻa a me nā wahi noho
Noho ka iʻa i ka wai o ka Moana Arctic holoʻokoʻa. Ma ka ʻāina ʻo Pechora, ua hui pū ʻia ka māhele hoʻolaha o nā mea kūʻai ʻEulopa a me Siberia. Loaʻa ʻia nā mea kūʻai Siberia ma ʻAmelika ʻĀkau. Eia kekahi, hiki ke loaʻa ka iʻa ma kekahi mau mokupuni ʻākau (Novosibirsk Islands, Kolguev). Ma nā muliwai, mālama ʻo ia i nā wahi hohonu me ka wai palupalu. Ua like ke ʻano o ka iʻa me nā iʻa keʻokeʻo ʻē aʻe. Ma nā loko, noho mamao ia mai ke kahakai, neʻe nā kula iʻa e ʻimi i nā hōʻiliʻili zooplankton. ʻO nā kānaka nui, i loko o nā loko, noho i ka hohonu, i kekahi manawa a hiki i 15 m.
ʻOhana
E lilo ia i mea makua kāne i ka makahiki 3-4 makahiki. Hoʻopuka nā ʻano Anadromous i loko o nā kahawai ma ke kahawai, ma ka lalo pōhaku-sandy. Hana ʻia ka spawning i ka hāʻule, ma muli o nā kūlana kūlohelohe, hiki ke hoʻolōʻihi a hiki i ka hoʻomaka ʻana o ka hoʻoilo. I kekahi mau loko o ʻEulopa ʻĀkau, ʻike ʻia nā ʻano me ka puna puna. Hiki i ka iʻa ke hoʻohua i ka hohonu.
