ʻAno like kahi iʻa asp me ka iʻa keʻokeʻo, akā nele ʻo ia i kahi fin adipose liʻiliʻi ma waena o ka huelo a me ka fin dorsal. He waha nui ko ka asp ma lalo o nā maka. Piʻi ia a i hoʻokahi mika ka lōʻihi a kaupaona ma kahi o 10 kg.
Hōʻike o ka iʻa asp
He kino elongated a pili ʻia me ke poʻo lōʻihi lōʻihi, ka hapanui o ke kālā i ke kala, ʻeleʻele-ʻoliva a hina hina hina hoʻi ke kua. He silvery ka iris, me kahi pōʻai gula liʻiliʻi a puni ka haumāna a me kahi pigment hina iki ma ka hapalua luna. He silvery nā lehelehe, hina ma ka ʻaoʻao o luna, ua loaʻa nā hiʻohiʻona me nā lehelehe ʻulaʻula a me nā irises. Pālahalaha ka piko o ka iwi ā lalo a komo i ka maha i ka iwi ā luna.
Hoʻopili liʻiliʻi nā lālā lālā i ka isthmus, kokoke ma lalo o ka hope hope o ka maka. Loaʻa i nā laha i nā niho pharyngeal elongated, spaced spaced, hooked.
Hinahina ke kua a me nā lau caudal, ke aniani o nā koena me ka ʻole o ka pigment, ʻo ka peritoneum mai ka silvery a i ka brown.
Ma hea ʻoe e hopu ai
Loaʻa ʻo Asp ma ka Rhine a me nā kahawai ʻākau ma ʻEulopa. Noho i nā waha o nā kahawai e kahe ana i loko o ke kai ʻEleʻele, Caspian a me Aral, me ko lākou kahakai hema. Kūleʻa ʻia ka iʻa i nā kūlana non-endemic no ka lawaiʻa ʻana ma Belgique, Netherlands, a me Palani. ʻO nā hoʻāʻo e hoʻopiha i nā waihona wai me asp i hana ʻia ma Kina a me Italia.
ʻO Asp kahi ʻano muliwai e noho ana i nā kahawai, nā kahawai a me nā backwaters. Hoʻolilo ka iʻa i ka hoʻoilo i loko o nā lua hohonu, ala aʻe i ka puna, ke piha nā kahawai a hele i loko o nā wahi e hānau ai, aia i loko o nā moena kahawai, nā wahi hāmama o nā loko me kahi kahawai nui, a i nā manawa liʻiliʻi wale nō e ulu nāwaliwali loa kēia mau wahi me nā mea ulu nunui, e like me nā ʻohe a me nā ʻohe.
ʻO Biology hānau
Hele ka iʻa i uka no ka hānau ʻana mai ʻApelila a Iune. Hana ka spawning i loko o ka wai e kahe wikiwiki ana i kahi lepo one a ʻiliʻili paha. Pili nā lāʻau caviar i nā ʻiliʻili a i ʻole nā mea kanu i hoʻokahe ʻia. Hoʻokipa ka hoʻouluulu i 10 mau lā, waiho ka wahine i nā hua he 58,000-500,000 me ke anawaena o ≈1.6 mm. ʻO ka hānai a Asp he 4.9-5.9 mm ka lōʻihi. Hiki i kēlā me kēia kanaka ke oʻo moekolohe ma 4-5 mau makahiki.
He aha ka asp e ʻai ai
ʻO kēia iʻa wale nō ka ʻano ʻai iʻa i loko o ka ʻohana carp. I ka wā mua o ke ola, hānai ka asp i nā crustacea, nā holoholona benthic, nā mea kolo terestrial i ka wai, a me nā iʻa iʻa. ʻO nā meaʻai nui a koʻikoʻi no nā asp mākua:
- pohō;
- lōkahi;
- iʻa gula.
ʻAi pū ka asp old i ka iʻa i ʻai ʻole nā ʻōpio congeners ma muli o ke alo o ke kākalaioa, e like me:
- kau;
- ruff maʻamau;
- one goby;
- manaʻo.
ʻAi pū ʻo Asp:
- Pākuʻi ʻo ʻEulopa;
- lāʻau-spined stickleback;
- gudgeon maʻamau;
- chub;
- podust maʻamau;
- verkhovka.
Pōmaikaʻi waiwai
ʻImi ʻia ʻo Asp no ka lawaiʻa haʻuki ʻana, a he waiwai waiwai ka iʻa i kēlā me kēia kanaka lawaiʻa wale nō. Hoʻokumu ka lawaiʻa hoʻokipa a me ka mākaʻikaʻi i ka noi no ka meaʻai, kahi noho a me nā halihali, hoʻomoana, hoʻokele waʻa, waʻa a ʻoi aku. Hoʻololi ka haʻuki haʻuki no asp i ka ʻoihana hoʻokipa kūloko.
ʻAʻohe mahiʻai nui no ka hoʻoulu ʻana i kēia laha. Hoʻopaʻa ʻia ʻo Asp i ʻIrani ma ke ʻano he iʻa meaʻai, akā hana wale ia i kahi ʻāpana liʻiliʻi o ka hopu.
Ka hopena ma ke kaiapuni
Ua hoʻonohonoho ʻia ʻo Asp i loko o nā kino wai mai ka hopena o ke kenekulia iwakālua. ʻAʻohe hopena maikaʻi ʻole o ka iʻa i nā wahi hou, ʻaʻole pili i ka heluna o nā iʻa endemik.
ʻO ka manawa kūpono loa e hopu i ka asp
Maʻalahi ke kiʻi koke ʻana i ka iʻa ma hope o ka hānau ʻana a i ka wā o ka mahina piha ke hānai nei ka asp. Ma ka laulā, hopu ʻia ia i ke ao a me ka pō, me ka ʻokoʻa o ka wā hoʻouluulu
