ʻAi ʻia ka hapa nui o nā iʻa i kēlā me kēia ʻano. Nui nā mea maikaʻi i ka palai ʻia, puhi ʻia kekahi i ka uahi, paʻakai, maloʻo, maikaʻi kekahi no ka baila iʻa iʻa iʻa. Akā aia kekahi iʻa like ʻole, kahi e hiki ai iā ʻoe ke kuke i kēlā me kēia mea, a ʻono hoʻi kekahi ipu. Manaʻo ʻia kēlā ʻano iʻa sabrefish.
ʻO ka helehelena o ka sabrefish
ʻO Chekhon kahi ʻohana nui o nā iʻa carp. He iʻa kula kēia, iʻa semi-anadromous e noho nei i ka wai hou. Ma waho, kahi iʻa hoihoi, a me kāna hiʻona ʻano nui he mau unahi alohilohi liʻiliʻi, me he mea lā i uhi ʻia me ke kālā. Hoʻopili ikaika ʻia ke kino mai nā ʻaoʻao, liʻiliʻi ke poʻo, me nā maka nunui a me ka waha ʻōwili paʻa.
Hoʻohui ʻia, ʻano ʻokoʻa ke kinona o kona kino - pololoi loa kona kua, ʻāpiki kona ʻōpū. Ma muli o kēia nā hiʻohiʻona o ka saber i kapa ʻia hoʻi he saber, saber, ʻaoʻao, Czech. He kīʻaha ko ka ʻōpū me ka unahi ʻole. ʻO ka waihoʻoluʻu o nā unahi iʻa ma ke kua ʻōmaʻomaʻo a me bluish, a ʻo nā ʻaoʻao he kālā.
Hinahina nā fin o ke kua a me ka huelo, ʻo ka ʻulaʻula nā ʻāpana lalo. Nui loa nā peʻa pectoral, no kahi iʻa o kēia nui, a ʻano like me ke kino o ka sabrefish. ʻĀpana Sensory - laina laina, aia i kahi ʻano zigzag, kokoke i ka ʻōpū.
Liʻiliʻi ka iʻa Czech, 60 cm ka lōʻihi o ke kaupaona, 2 kg ke kaumaha, akā ʻo kēlā mau kānaka no nā hiʻohiʻona trophy, no ka mea liʻiliʻi loa lākou. Ma ke ana pāʻoihana, ʻohiʻohi ʻia nā poʻe liʻiliʻi - ʻo ka nui maʻamau no lākou he 20-30 cm ka lōʻihi a 150-200 gram o ke kaupaona. ʻO kēia mau Czechs liʻiliʻi hiki ke kūʻai pinepine ʻia i ka hale kūʻai i kahi ʻano maloʻo a puhi paha. Sabrefish maloʻo iʻa ono loa.
Kahi noho Sabrefish
ʻO Chekhon kahi iʻa semi-anadromous i loko o nā ipu o ke kai Baltic, Aral, Black, Caspian a me Azov. Noho nui ia i ka wai hou, ʻoiai hiki ke ola i nā salinity a hana i nā ʻano noho i ke kai.
ʻO ka wahi noho o ka sabrefish nui loa - ʻo nā wahi o kona wahi noho mau me Russia, Polani, Kelemania, Palani, Romania, Hungary, Bulgaria a me nā ʻāina ʻē aʻe he nui o ʻEulopa a me ʻAsia. ʻO ka hapa nui o nā kahawai ʻo Dnieper, Don, Dniester, Danube, Kuban, Western Dvina, Kura, Bug, Terek, Ural, Volga, Neva, Amu Darya a me Syrdarya.
Inā mākou e kamaʻilio e pili ana i nā loko, a laila nui ka nui o ia e noho nei ma Onega, Ladoga, Lake Ilmen a me nā loko Kelif. Noho pū kekahi ia i nā waihona wai. ʻOiai kona wahi nui, i kekahi mau wahi sabrefish he lāhui ʻaneʻane make a pale ʻia e nā luna. Aia kēia mau wahi i ka piko o ka Dnieper ma ka moku ʻo Bryansk, ka muliwai ʻo Severny Donets, Lake Chelkar.
Makemake ʻo Chekhon i nā waihona kai waena a me nā wai nui; ʻaʻole hiki ke loaʻa i nā kahawai liʻiliʻi a me nā loko. Koho i nā wahi hohonu a hoʻonui ʻia. I kekahi manawa hoʻolilo ʻo ia i ka manawa ma ka shoals, akā aia wale nō ke holo wikiwiki. Aloha i nā wahi kokoke i nā kahawai wai ʻino a me nā kahawai. ʻAʻohe iʻa e holoholo kokoke ana i ke kahakai.
ʻO ka nohona Sabrefish
ʻEleu ka iʻa saber, ola a makaʻu ʻole hoʻi. I ka lā e neʻe mau ʻo ia, akā ʻaʻole neʻe mamao aku mai kāna "wahi noho" mau. I ke kauwela, piʻi ka iʻa i luna o ka wai i ke awakea, i ka ʻimi ʻana i ka meaʻai. I ka pō, poholo ia i lalo a hūnā ma laila i nā ʻano hale like ʻole, nā kūlike ʻole o ka lalo.
Ua like ia ma hope kauwela anu anu, sabrefish mālama ia i kahi hohonu, a hoʻolilo i nā mahina hoʻoilo i loko o nā lua a me nā whirlpools, e waiho ana ma laila i nā pūʻulu o nā kānaka he nui. Inā ʻaʻole paʻakikī ka hoʻoilo, a laila neʻe iki nā kula iʻa, i ke anuanu loa e paʻa paʻa ia ma lalo, ʻaʻole ʻai pono, no laila i kēia manawa hopu sapere hana ʻole ʻia.
I ka puna, ʻākoakoa ka wahine Czech i nā kula nui a hele i ka ʻōpala. I ka hāʻule, hui hou ia i nā pūʻulu a hoʻomākaukau no ka hoʻoilo. I loko o kēia wā, alakaʻi ʻo ia i kahi nohona hana a hānai nui.
Meaʻai sabre
ʻAi ikaika ʻo Chekhon i nā mea kanu a me nā holoholona i ke ao. Hana ʻia ia, i ke kau kau, lele i waho o ka wai e hopu i nā kolo e puni ana ma luna ona. ʻAi nui nā iʻa ʻōpio i ka zoo a me ka phytoplankton. A ke nui ʻo ia, ʻai ʻo ia i ka larvae, nā ilo, nā kolo a me nā iʻa like ʻole.
Inā ʻohi wale ʻo ia i nā mea kolo mai lalo a hopu iā lākou ma luna o ka wai, a laila e ʻimi ʻo ia i ka ʻai. ʻAʻau pinepine ka wahine Czech me nā mea i hōʻino ʻia i ka ʻohana like, a laila hopu koke i ka mea pio a hele i lalo me ia. A laila hoʻi ʻo ia no kekahi aʻe. Hoʻouka koke kēia iʻa ola me ka ʻeleu a me ka wikiwiki.
ʻIke ʻia kēia hiʻohiʻona i nā lawaiʻa, ʻike pū lākou i ka sabrefish ʻaneʻane omnivorous, no laila, ʻaneʻane hoʻohana ʻia nā mea kolo e like me ka maunu: nā ʻūlū, nā ilo lepo, nā lele, nā pi, nā ʻūhū, nā dragonflies a me nā holoholona ʻē aʻe. Hoʻohui ʻia, hiki i nā iʻa ke ʻūlū ma kahi lou hakahaka, i nakinaki wale ʻia me ke kaula ʻulaʻula a i ʻole kahi e komo ai kahi lei.
ʻO ka hana hou a me ke ola o ka sabrefish
Hiki i ka sabrefish ke hana hou ma 3-5 mau makahiki (i nā wahi hema ma mua iki - e 2-3 mau makahiki, ma nā ʻākau e 4-5). Hoʻomaka ia e spawn i Mei-Iune, a hana nā iʻa liʻiliʻi i kēia ma mua o ka poʻe nui. ʻO ke kumu nui no ka hoʻomaka ʻana o ka ʻōnaehana ʻana he mahana o ka wai o 20-23 Cº, no laila, hoʻomaka hou ka ʻōpū ʻana i nā wahi hema.
Ma mua o ka hānau ʻana, ʻai liʻiliʻi ka sabrefish, ʻohiʻohi i nā shoals nui a nānā i kahi e waiho ai nā hua. Kūpono nā wahi me ka ʻāpana ikaika a me ka hohonu o 1 a 3 mau mika, he pāpaʻu kēia, ke kuha one, nā kahawai kahawai.
Kū ka spawning i ʻelua mau holo ma ka hema, a ma ka manawa like ma nā ʻĀkau ʻākau. I nā kahawai, spawns ka sabrefish, neʻe i uka, a laila ʻōwili i lalo i lalo. ʻAʻole pili nā hua, no laila ʻaʻole pili lākou i ka limu a i ʻole nā mea ʻē aʻe i loko o ka wai, akā e paheʻe i lalo.
ʻO lākou ka 1.5 mm o ka nui. i ke anawaena, a laila, ma hope o ka momona, hoʻonā i ka lalo a pehu ma laila, e hoʻonui ana i ka nui a 3-4 mm. Kaukaʻi ʻia i ka mahana o ka wai, pala nā hua i 2-4 lā, a laila ka huki ʻana o 5mm fries mai iā lākou.
Ulu koke ka iʻa, e hānai nei i kā lākou waihona yolk ponoʻī, e huddling ana i nā hipa liʻiliʻi a neʻe i kahawai. Ma hope o 10 mau lā, hoʻololi lākou i plankton, a hānai iā ia no kahi manawa lōʻihi. Ulu wikiwiki ka sabrefish no nā makahiki he 3-5. A laila lohi ka ulu ʻana, no laila, me ke ʻano o ke ola ma kahi o ʻumi mau makahiki, kākaʻikahi ka hiki i kekahi ke hopu i kahi kanaka nui loa.
