ʻO ka piranha maʻamau he iʻa predatory mai ka ʻohana nui o characin-piranhas. He paʻakikī ka loaʻa ʻana o ke kanaka ʻike ʻole i ke ola o kēia iʻa. Mai ka wā kamaliʻi, mai nā kumu like ʻole, haʻi ʻia mākou e pili ana i ke koko koko o ka piranha. He ʻoiaʻiʻo nō ka maikaʻi o kēia ʻano ʻaʻole maopopo i nā manawa a pau kahi ʻoiaʻiʻo a ma hea kahi moʻolelo. Pono e hoʻomaopopo ʻia ʻaʻole pono e manaʻo ʻia nā iʻa a pau o kēia ʻohana he pōʻino. No ka laʻana, metinnis (Metynnis) a i ʻole genera iʻa ʻo Colossoma (Colossoma) a me Mileus (Myleus), ke kumu o ka ʻai ʻana o ia mau ʻano mea kanu like ʻole. No nā mea ʻaihue, ua hōʻike ʻia lākou e kekahi mau genera, me ka mea kaulana loa, ka piranha maʻamau (Pygocentrus nattereri). He iʻa liʻiliʻi kēia, ʻo 15-20 cm ka lōʻihi. Akā hiki i ka nui ke kiʻekiʻe a hiki i 50 cm a hiki i ka 4 kg. Ma keʻano laulā, ma waena o nā ʻano piranhas ʻē aʻe, aia nā kānaka ma mua o 1 m ka lōʻihi. ʻO ke kino o ka iʻa he ʻano poepoe, palahalaha ikaika mai nā ʻaoʻao. No ka piranha maʻamau, ʻo ke kala o ke kino luna he ʻoliva ʻeleʻele, a ʻo nā ʻaoʻao he kala. Ua uhi ʻia ke kino holoʻokoʻa me nā unahi liʻiliʻi. I ka wā ʻōpiopio, ʻulaʻula ka iʻa, i ka wā makua, lilo lākou i ʻeleʻele. Ma keʻano laulā, he hiʻohiʻona kēia hiʻohiʻona o nā ʻano nui a pau. ʻElua mau peʻa ma ke kua, he liʻiliʻi ke kua a neʻe i ka huelo. He mau lehelehe ʻiʻo ko nā iʻa a pau o ka ʻohana, a e pōʻino pinepine ʻia i ka wā hahai holoholona a me nā hakakā ma waena. He nui ka nui o na niho o na auwae. Hoʻoneʻe ʻia ka iwi ā lalo i mua, a ʻoi aku ka ʻoi aku o ka ferocity i ke ʻano. ʻO ka lōʻihi o nā niho nui loa o ka iwi ā lalo hiki ke hiki i 2 knm. ʻO ka ikaika o ka hoʻopaʻa ʻana i ka iwi e like me 320 Newtons. Nui ka poʻe Piranha a noho i nā wahi like ʻole o ka muliwai. Hana lākou i nā ʻohana nui. He poʻe ʻaihue ikaika lākou, e hilinaʻi ana i ka wikiwiki o ka hoʻouka ʻana a me ka pīhoihoi. I loko o kahi hui, hoʻouka lākou i nā mea i hōʻeha ʻia i kēlā me kēia nui. I ka ʻimi ʻana i ka poʻe i hōʻeha ʻia, hilinaʻi lākou i kahi ʻano koʻikoʻi o ka honi, ʻike a me ka laina lateral. I loko o ka ʻohana iʻa ʻē aʻe, ʻike koke ʻia nā maʻi a me nā ʻeha, ʻo ia hoʻi, ʻike koke ʻia ka poʻe i hāʻule i ka hopohopo, a lilo ia i hōʻailona e hoʻouka. He mea pono e hoʻomaopopo he hiki i nā piranhas ke hana i kahi symbiosis me kekahi mau iʻa ʻē aʻe, e hoʻomaʻemaʻe iā lākou mai nā parasites, ʻaʻole lākou e ʻimi iā lākou. ʻAʻole hoʻouka ʻo Piranhas i ko lākou ʻohana ʻeha. Hoʻōla koke ka pōʻino i ke kino o nā piranhas. ʻAʻohe hihia maoli o ka poʻe i pepehi ʻia. ʻO kekahi mau ʻano piranhas kūikawā i ka ʻai ʻana i nā unahi o nā iʻa ʻē aʻe a i ʻole nā ʻili o nā ʻano nui. Hiki nō naʻe ke ʻai i nā ʻōpiopio o nā iʻa ʻē aʻe. ʻO nā mea ʻē aʻe he loea i nā hua o nā mea kanu kokoke i ka wai. ʻAʻole loa e nalo nā mea ʻaihue i nā ʻelele like ʻole o nā invertebrates, mollusks a pēlā aku.
Nā ʻano lawaiʻa
Ma muli o ka nui o nā ʻano, aggressiveness a me ka voracity, he mea maʻamau a maʻamau lākou o ka lawaiʻa ʻana ma nā kahawai o ka tropical zone o nā muliwai o ʻAmelika Hema. ʻO ka hopu ʻana i nā piranhas ma nā maunu kūlohelohe ʻaʻole pono nā lako kūikawā, ʻike a me nā mākau. He nui ka poʻe i ʻike i nā kiʻi o nā kamaʻāina e hopu ana i nā piranhas me ka ʻole o nā koʻokoʻo a me nā makau, me ka hoʻohana ʻana i nā ʻokiʻoki mai nā kino holoholona a iʻa paha. Mai ka manaʻo kuko, e hoʻokomo nā piranha i ko lākou mau niho i loko o ka ʻiʻo, a kau mau ma luna ona, pono ʻoe e ʻohi a hoʻolei i uka. He ʻono loa ka ʻiʻo iʻa a hoʻohana ʻia no ka ʻai. I ka lawaiʻa ʻana me nā nozzles like ʻole me ka hoʻohana ʻana i nā mea hoʻohana amateur, pono ia e hoʻohana i nā lei ikaika, hiki paha i ke kaula metala maʻamau. Pono nā leashes, ʻoiai ke hopu ʻana i nā piranhas herbivorous. ʻO ka hapa nui o ka poʻe lawaiʻa e hele mai ana i nā muliwai wela o ʻAmelika e hoʻāʻo e hopu i nā ʻano iʻa like ʻole. A, ma ke ʻano he kānāwai, lilo nā piranhas āpau i "pilikia": ma muli o ka nahu pinepine, paʻakikī lākou i ka nānā ʻana i ka ʻelele i koho ʻia o ka ichthyofauna. ʻO nā ala kaulana loa o ka lawaiʻa ʻana i nā piranhas hiki ke noʻonoʻo ʻia i ka lawaiʻa me nā mea hana like ʻole me ka hoʻohana ʻana i nā maunu maoli. ʻO ke ala kaulana ʻelua o ka lawaiʻa amateur ʻo ka wili.
Ka hopu ʻana i ka iʻa ma ke koʻokoʻo wili
E like me ka mea i ʻōlelo mua ʻia, pili pinepine ʻia ka hopu ʻana i nā piranhas i ka wili ʻana me ka hopu ʻana iā lākou ma ke ʻano he bycatch. Inā makemake ʻoe e lawaiʻa i nā piranhas, a laila ʻo ka mea nui o ka mea hana ʻo ia kona ikaika. ʻO ka mea mua, he mau leashes a me nā makau. E like me ka mea i haʻi mua ʻia, ʻo ka leash hilinaʻi loa hiki ke lilo i ʻāpana uea metala. Akaka ke kumu - ka nui o nā niho conical ʻoi e hiki ke luku i nā iwi. A i ʻole, ʻoi aku ka pili o nā ala i ke koho ʻana i nā maunu a me nā mea pono ponoʻī i ka ʻike pilikino o ka mea lawaiʻa a me kāna mau makemake. I ka noʻonoʻo ʻana i nā ʻano nui o nā piranhas he iʻa liʻiliʻi, hiki ke hoʻohana ʻia nā mea wili o nā papa māmā no ka lawaiʻa kūikawā. Akā, mai poina i ka nui o nā iʻa i loko o nā muliwai wela ke kumu o nā nahu i manaʻo ʻole ʻia, kahi ma kahi o kahi piranha liʻiliʻi, hiki i kahi iʻa iʻa i ke kaupaona ʻana he mau kilokani ke nahu.
Maunu
ʻO ka maunu nui no ka hopu ʻana i nā piranhas predatory he mau maunu maoli o nā holoholona. I ka hihia o ka lawaiʻa me nā lures artificial, pono ke koho ʻia ma ke kumu o ka ikaika kiʻekiʻe. A i ʻole, hiki i ka lawaiʻa ke lilo i "mau pani pau ʻole" o nā maunu. No ka hopu ʻana i nā ʻano predatory, hoʻohana pinepine ka poʻe kamaʻāina i nā hua o nā mea kanu, hiki i ka iʻa ke hana kūikawā i ka hānai ʻana.
Nā wahi lawaiʻa a me nā wahi noho
He mea pono e hoʻomaopopo he 40 mau ʻelele ma ka ʻohana piranha, a aia nō paha nā ʻano i wehewehe ʻole ʻia. Ua uhi ʻia ka māhele ʻāina i nā wahi nui o nā kahawai a me nā loko i ʻAmelika Hema: Venezuela, Brazil, Bolivia, Argentina, Colombia, Ecuador a me nā ʻāina ʻē aʻe. Ma nā muliwai pili i nā wahi like ʻole, akā kakaʻikahi ka noho ʻana ma nā kahawai. Holo ikaika nā ʻohana ma ka pūnāwai.
ʻOhana
ʻOkoʻa loa ka ʻano hana o ka piranhas. Hāpai nā ʻano ʻano like ʻole i nā manawa like ʻole. Ua ʻike ʻia ua ʻike ʻia nā piranhas e nā pāʻani pre-spawning lōʻihi, kahi i hoʻokumu ʻia ai nā pālua. Hoʻomākaukau nā kāne i kahi no ka hoʻoulu ʻana a mālama ikaika i ka masonry. ʻO nā wahine Piranha he hua nui loa: waiho lākou i mau tausani hua. ʻO ka manawa incubation e pili ana i nā kūlana wela kūloko o ka waihona.
