ʻAno like loa me ka moa, nani a koʻikoʻi iʻa ide me kona kala gula o nā unahi, ua loaʻa ia i loko o ʻaneʻane nā waihona wai o ʻEulopa. Hele wale lākou ma ka hema a me ka hikina hikina.
E ʻike manaʻo hiki i nā loko a me nā kahawai o Siberia a me ʻAmelika Hema. I Rūsia, aneane kēia wahi iʻa i nā wahi āpau. ʻAʻole ʻoe e loaʻa ma Yakutia a ma ka Hikina wale nō. Kiʻi o ka manaʻo hōʻoiaʻiʻo nō i nā huaʻōlelo he ʻano like kona me ka roach. ʻO kaʻokoʻa ma waena o lākou i ke kala o nā maka a me ka nui o nā unahi. He maka melemele ko ka iʻa ide a ʻoi aku ka liʻiliʻi o ka unahi ma mua o ko roach.
Nā hiʻohiʻona a me nā wahi noho
I ka nānā mua ʻana, ʻaʻole ʻokoʻa kēia iʻa mai nā mea ʻē aʻe ʻē aʻe. Hōʻike o ka iʻa ide hōʻike wale i kekahi o nā ʻokoʻa ma waena o lākou. Hinahina kona mau unahi me ke aniani gula. ʻOi aku ka māmā o ka lalo ma mua o ka top. Nānā koke nā poʻe āpau i ke kala momona o nā maka o ka ide. He ʻulaʻula kā nā lau o nā iʻa; ʻālohilohi loa lākou i ka ʻāina o ka anus a ma ka ʻaoʻao o ka ʻōpū.
ʻO ke kino o ka iʻa ke nānā nui a mānoanoa. ʻAʻole liʻiliʻi ka iʻa. ʻO ka lōʻihi o kahi kanaka makua maʻamau mai 30 a 50 mau kenimika. Akā ʻike pinepine ʻia nā id a hiki i ka 1 mika ka lōʻihi. ʻO ke kaulike kaulike o nā iʻa ma kahi o 1 kg, akā i kekahi manawa hiki aku ko lākou kaumaha i 6-7 kg. ʻIke maopopo ʻia kahi lae kaulana ma kona poʻo liʻiliʻi. Kaulike ʻole ka waha o ka iʻa.
He wai hou ia ide iʻa muliwai hiki ke maʻalahi i ka wai paʻakai, no laila hiki ke loaʻa i kekahi manawa i nā kai kūʻono. Aloha ʻo ia i nā kahawai hohonu, me kahi au lohi, nā waihona wai me nā lua a me nā loko, kahi lepo pālolo a me lalo i hū ʻia.
Makemake lākou i kahi ola aloha. Makemake lākou e kū i nā pūʻulu e pili ana i nā snag i piholo ʻia, i nā loko wai ma lalo o nā dam. Mai kēia mau wahi haʻalele lākou i kēlā me kēia manawa e kiʻi i nā meaʻai na lākou iho i nā wahi me kahi kahe maʻamau.
ʻAʻole ia he mea maʻamau ke ʻike aku i nā pūʻā o ka manaʻo e hele wāwae ana ma ke kapa o ka muliwai. Hana ʻia kēia ma hope o ka hala ʻana o kahi ua maikaʻi. Hiki i nā kula o kēia iʻa ke huakaʻi i kahi mamao aku no ka hoʻoulu ʻana a i ka hoʻoilo paha. Kuhi ʻia ka mamao ma kahi o nā haneli mau kilomita.
Oi aku pinepine ola ka manaʻo ma ka palena o nā kahe wikiwiki me ka wai mālie. Ma laila lākou e mālama ai i kahi nui o nā hānai like ʻole. ʻAʻole makemake ka manaʻo i ka piko o nā kahawai mauna kiʻekiʻe, i loko o ka wai kahi haʻahaʻa haʻahaʻa o ka oxygen, a paʻakikī ʻole ia.
Hana nui kēia iʻa i ke kau hoʻoilo. Hoʻāʻo ʻo ia e noho i nā wahi hohonu, waiwai nui i nā snags. Hiki i ka ide ke hoʻohana i ka lua wale nō i ke aniau ʻino a me ka hau hau loa. Koke ma hope koke o ka hoʻoheheʻe ʻana o ka hau, mālama kēia mau iʻa i nā kahua huki.
ʻO ke ʻano a me ka nohona
I ke kauwela, pili mau ka manaʻo o ka ʻohana iʻa i ke kapakai. No laila, ʻoi aku ka maʻalahi o ka mālama ʻana i kāna meaʻai. ʻOi aku ka maʻalahi a me ka hana no nā mākua o kēia iʻa i kahi kaʻawale nani. Mālama nui ʻia nā iʻa ʻōpio i nā kula.
I ka hoʻoilo, hoʻāʻo lāua ʻelua e hui a noho pū. He iʻa paʻakikī nui kēia. ʻAʻole paʻakikī iā ia ke hoʻomanawanui i nā kekelē like ʻole o ke ʻano mahana o ka wai a me kona haumia. Akā hāʻawi ia i ka makemake i nā wai me nā punawai a me nā puna i kahi nui aʻe.
E pili ana i ka iʻa ide ʻike ʻia ʻo ia e akahele loa. ʻO kekahi walaʻau a i ʻole kahi makaʻu liʻiliʻi e hana iā ia me ka wikiwiki o ka uila. I ka hapanui o nā hihia, hoʻāʻo ka iʻa e neʻe i hope, e lele ana i ka wai i ka lewa ke holo. Hoʻomohala maikaʻi ʻia kona ʻala, no laila hiki iā ia ke honi i ka maunu ʻala mai kahi mamao aku.
I ke kau hoʻoilo, hele ka manaʻo i ka hohonu a noho mau ma laila a i ka hopena o ka hoʻoilo. ʻ saylelo nā lawaiʻa ʻike loea e pili ana nā manaʻo i nā perches. Me ka hōʻea ʻana o ka pūnāwai, hoʻomaka nā iʻa e ʻākoakoa i nā kula a piʻi i luna o ke kahakai. A i ka wā e hoʻokuʻu ʻia ai nā kahawai mai ka hau, piʻi nā pua o nā ide i uka.
I ka manawa ke haʻalele ka hau a kahe nā kahawai, aia nā ʻohana hipa kokoke i nā kapa. Akā ʻaʻole ia e neʻe ma ʻō aku o ka moe o ka muliwai. ʻO kēia no ka mea hoʻomaka lākou i ka hoʻonui ʻana i ka ulu. He iʻa iʻa roe ʻaʻole e make i ka hāʻule wikiwiki ʻana o nā wai puna inā koe ia i ka muliwai. Ua ʻike ka nui o nā lawaiʻa hiki i ka ide ke piʻi i kahi mamao o 150 km.
Ma hope o ka hānau ʻana, peʻe lākou i ka hohonu o ka waihona wai. Ma hope wale nō o kahi manawa hiki ke ʻike ʻia lākou ma nā one one, kahi a lākou e piʻi ai e hānai. Aia i kēia manawa kēlā lawaiʻa ide i kekahi ʻano, mai ke koʻokoʻo iʻa i nā mea lawaiʻa ʻē aʻe.
Mea ʻai
ʻAʻole kū iki kēia iʻa i ka meaʻai. ʻO ka manaʻo, ʻōlelo paha kekahi, he omnivorous. Nā mea kanu like ʻole, nā ʻelala, molluscs, nā ilo - makemake ʻo ia i nā mea āpau. Kūpono ʻo ia i nā wahi i nui nā mea kanu a me nā limu. Kūpono kēia papaʻai no ka ide liʻiliʻi. Ke piʻi kona kaumaha i 600 mau gram a hoʻonui i ka nui, hiki i ka ide ke ʻai i nā iʻa liʻiliʻi.
Hoʻohana pū ʻia nā Tadpoles a me nā rana liʻiliʻi. ʻIke ʻia ke ulu nui ka makemake o kēia iʻa ke pua ka viburnum. ʻO kēia ka manawa e hoʻomaka ai nā lele e lele i waho ka lehulehu, kahi mea ʻai punahele a nā iʻa he nui, e like me ka manaʻo Akā ʻo ka meaʻai kumu nui loa no kēia iʻa ka larvae o nā iʻa aquatic.
ʻO ka hana hou a me ke ola o ke ola
Mai ka hopena o ʻApelila, hoʻomaka ka wā hānau no ka ide. I nā ʻĀkau o ka ʻākau, neʻe ka manawa o ka spawning ma kahi o hoʻokahi mahina a hiki i ka hoʻomehana ʻana o ka wai. Ua lawa kekahi mau lā ʻelua no lākou e kūlia i kēia hana. Aia nā hoʻokoe ke ʻaʻole wela ka wai. I kēia hihia, hoʻopaneʻe iki ka manawa huki ʻana.
Hana ʻia ka ʻōmau i ke kakahiaka a me ke ahiahi. Inā mahana ka wā, hoʻolōʻihi kēia hana a hiki i ke aumoe. ʻO nā mea kūikawā o ka iʻa ide ka mea e hoʻāʻo e hoʻopili i kā lākou mau hua ma nā pōhaku a i ʻole nā mea kanu wai, ʻaʻole hiki ke hoʻopakele mau iā ia mai ke kahe wikiwiki o ka wai.
I kekahi manawa hiki ke ʻai ʻia nā hua moa ide e nā kamaʻāina ʻē aʻe o nā waihona. I ka wā o ka hoʻomoe ʻana i nā hua, lilo kēia iʻa akahele akahele i mea nānā liʻiliʻi a hiki ke lilo i maʻalahi no nā lawaiʻa. Manaʻo caviar he melemele kona ʻano a ʻokoʻa hoʻi i nā hua iʻa ʻē aʻe. Hiki i hoʻokahi ide ke moe mai 42 a 150,000 mau hua. ʻO ka lōʻihi o ke ola o kēia iʻa ma kahi o 15-20 mau makahiki.
