kāpī wai
Pistia layered a i ʻole Kāpena wai, inoa ʻepekema Pistia stratiotes. Wahi a kekahi manaʻo, ʻo ka wahi hānau o kēia mea kanu he mau wai kūʻokoʻa kokoke i Lake Victoria ma ʻApelika, e like me kekahi - nā puʻu o ʻAmelika Hema ma Brazil a me Argentina. ʻO kekahi ʻaoʻao a i ʻole, ua laha ʻia i nā ʻāina āpau me ka ʻole o Antarctica. Ma nā wahi he nui o ka honua, he mauu ia e hakakā ikaika nei.
ʻO ia kekahi o nā mea kanu wai hou e ulu wikiwiki ana. I loko o nā wai momona, ʻoi aku ka poʻe i haumia i ka wai a i ʻole nā mea momona, kahi e ulu ai ʻo Pistia stratus. Ma nā wahi ʻē aʻe, me ka ulu ikaika ʻana, hiki ke hoʻopilikia ʻia ka hoʻololi kinoea ma ka ʻaoʻao o ka ea-wai, ke emi nei ka ʻike o ka oxygen dissolved, e alakaʻi ana i ka make nui o nā iʻa. Eia kekahi, kōkua kēia mea kanu i ka laha ʻana o nā makika Mansonia - nā mea lawe i nā kumu kumu o ka brugiasis, e waiho wale ana i kā lākou mau hua i waena o nā lau o Pistia.
E pili ana i nā mea kanu lana. Hoʻokumu i kahi pūpū liʻiliʻi o nā lau nui, ʻokiʻoki i ke kumu. He ʻeleʻele ʻeleʻele ka ʻili o ka lau ʻōmaʻomaʻo. Hoʻomaʻemaʻe maikaʻi ka ʻōnaehana kumu i hoʻomaʻemaʻe ʻia i ka wai mai nā mea kūlohelohe a me nā haumia. No kona hiʻohiʻona nani, ua hoʻokaʻawale ʻia ʻo ia ma ke ʻano he mea kanu aquarium ornamental, ʻoiai ma ka nahele, e like me ka mea i ʻōlelo ʻia ma luna, ʻoi aku ka nui o ka mauʻu weliweli. ʻAʻole koi ka kale wai i nā ʻāpana wai e like me ka paʻakikī a me ka pH, akā he thermophilic a pono i kahi pae kukui maikaʻi.
