ʻO ka meaʻai iʻa: he aha ka crayfish i maʻa i ka ʻai ʻana ma ke ʻano a me ka mea i hānai ʻia i ke pio

Ma nā ʻāina he nui (me Russia hoʻi), manaʻo ʻia ka ʻiʻo crayfish he mea ʻono. Hauʻoli nā kānaka i ka ʻai ʻana i kēia mea ʻono. Akā aia kekahi ʻano o ka poʻe i manaʻo ʻaʻole maikaʻi loa ka crayfish. ʻO ke kumu o kēia "hōʻino" he manaʻo wahaheʻe o uXNUMXbuXNUMXbka meaʻai o kēia arthropod.

Manaʻo kekahi, ʻai kēia mau holoholona i ka pala a me ke kino. Aka, he oiaio ole keia. Ma kēia ʻatikala e kamaʻilio mākou e pili ana i ka mea e ʻai ai kēia mau arthropod.

He aha ke ʻano holoholona?

Ma mua o ka kamaʻilio ʻana e pili ana i ka ʻai ʻana o ka crayfish, pono e ʻike i kēia mau mea noho arthropod o ka mea wai. ʻO kēia mau holoholona pili i nā crustacean invertebrate. Nui nā ʻano, e inoa i kekahi o nā mea maʻamau:

• ʻEulopa;
• Hikina loa;
• Cuban;
• Florida;
• kinikini;
• Pigmy Mekiko, etc.

Hoʻolaha nui ʻia nā maʻi maʻi ma nā ʻāina āpau. ʻO ko lākou wahi noho ʻo nā muliwai wai maʻemaʻe, nā loko, nā loko a me nā kino wai ʻē aʻe. Eia kekahi, hiki i kekahi mau ʻano ke ola ma kahi hoʻokahi i ka manawa hoʻokahi.

Ma waho, he mea hoihoi loa ka ma'i 'a'ai. Ua loaʻa iā ia ʻelua ʻāpana: cephalothorax a me ka ʻōpū. Aia ma ke poʻo ʻelua mau antennae a me nā maka hui. A ʻewalu mau lālā o ka pahu, ʻelua mau māiʻuʻu. I ke ʻano, hiki iā ʻoe ke ʻike i ka maʻi kanesa o nā kala like ʻole mai ka ʻeleʻele a me ka ʻōmaʻomaʻo a i ka polū-uliuli a me ka ʻulaʻula. I ka wā kuke ʻana, pau nā puaʻa a pau, ʻulaʻula wale nō koe.

Manaʻo ʻia ka ʻiʻo maʻi maʻi he mea ʻono no kekahi kumu. Ma kahi o ka ʻono maikaʻi loa, ʻaʻohe momona, no laila he haʻahaʻa haʻahaʻa ka calorie. Eia kekahi, he nui nā mea pono i loko o ka ʻiʻo. Aia ka calcium, a me ka iodine, a me ka huaora E, a kokoke i nā huaora a pau mai ka hui B.

He aha kāna ʻai?

ʻAʻole like me ka manaʻo kaulana e ʻai ana ka crayfish i ka pala, ʻaʻole lākou koho i ka meaʻai. No laila he aha ka mea e ʻai ai nā pāpaʻi? Inā loaʻa nā mea hoʻohui ʻia a me nā mea hoʻohui kemika i ka meaʻai, a laila ʻaʻole e hoʻopā kēia arthropod iā ia. Ma ka laulā, ʻoluʻolu kēia poʻe noho o nā loko i ka maʻemaʻe o ke kaiapuni. Ma nā kūlanakauhale he nui, "lawelawe" lākou ma nā lako wai. ʻO ka wai e komo ana iā lākou hele i loko o nā aquarium me ka crayfish. Ke nānā ʻia nei ko lākou ʻano e nā mea ʻike he nui. Inā loaʻa nā mea ʻino i loko o ka wai, a laila e hōʻike koke nā arthropods iā ʻoe.

ʻO nā crustaceans lākou iho he omnivores. Aia kā lākou meaʻai mai nā holoholona a me nā mea kanu. Akā ʻo ka lua o ka ʻano meaʻai ka mea maʻamau.

ʻO ka mea mua, e ʻai ʻo ia i nā limu i hopu ʻia, nā mauʻu kahakai a me nā lau hāʻule. Inā ʻaʻole loaʻa kēia meaʻai, a laila e hoʻohana ʻia nā ʻano lilia wai, huelo lio, sedge. Nui ka poʻe lawaiʻa i ʻike i ka ʻai ʻana o nā arthropod i ka ʻupena me ka leʻaleʻa.

Akā, ʻaʻole e hele ka maʻi kanesa ma muli o ka meaʻai holoholona. E ʻai ʻoliʻoli ʻo ia i nā ʻōpala a me nā pākeke, nā mollusks, nā ilo a me nā tadpoles. Kakaʻikahi, hiki i ka maʻi kanesa ke hopu i nā iʻa liʻiliʻi.

Inā mākou e kamaʻilio e pili ana i nā koena palaho o nā holoholona, ​​​​a laila ua manaʻo ʻia he mea pono kēia. Ke neʻe mālie nei ke kanesa a ʻaʻole hiki ke hopu i ka "ʻiʻo hou". Akā i ka manawa like, hiki i ka holoholona ke ʻai wale i ka meaʻai holoholona decomposed ʻole. Inā lōʻihi ka popopo o ka iʻa make, a laila e maʻalo wale ke ʻano.

Akā naʻe mea kanu ke kumu o ka ai. ʻO nā ʻano ʻano limu a pau, ka wai a me nā mea kanu wai, hiki i ka 90% o ka meaʻai. ʻAʻole ʻai ʻia nā mea ʻē aʻe inā hiki iā ʻoe ke hopu.

ʻAi wale kēia mau holoholona i ke kau mahana. Me ka hoʻomaka ʻana o ka hoʻoilo, loaʻa iā lākou ka pōloli koi. Akā i ke kauwela ʻaʻole ʻai pinepine ka holoholona. No ka laʻana, ʻai ke kāne i hoʻokahi a ʻelua paha i ka lā. A ʻai ka wahine i hoʻokahi wale nō i nā lā ʻelua a ʻekolu paha.

He aha kā lākou hānai iʻa i ka wā e hānau pio ai?

I kēia lā, ulu pinepine ʻia ka crayfish. No ka hana ʻana i kēia, hana ʻia nā mahiʻai ma nā loko, nā loko liʻiliʻi a i ʻole ka hoʻohana ʻana i nā pahu metala. No ka mea ʻo ka pahuhopu nui o ia ʻoihana ka loaʻa ʻana o ka nui nui, hānai lākou i nā arthropods me ka meaʻai nui ka ikehu. Hele e hānai:

• ʻiʻo (maka, paila a me nā ʻano ʻē aʻe);
• berena;
• cereals mai ka cereals;
• nā mea kanu;
• mea kanu (ʻoi loa ka crayfish aloha ʻupena).

I ka manawa like, pono e hāʻawi ʻia ka meaʻai i ʻai ʻia me ke koena ʻole. A i ʻole, e hoʻomaka ana ia e pala a e make wale nā ​​mea kolo. E like me ke kānāwai, ʻaʻole ʻoi aku ka nui o ka meaʻai ma mua o 2-3 pakeneka o ke kaumaha o ka holoholona.

I kēia mau lā, nui ka poʻe i hoʻomaka e mālama i kēia mau holoholona i loko o ka hale, i ka aquarium. Ma kēiaʻano, kū mai ka nīnau: he aha ka mea e hānai ai? Inā he hale kūʻai holoholona ma ke kūlanakauhale, a laila hiki iā ʻoe ke kūʻai i ka meaʻai ma laila. I loko o nā hui kūikawā no nā arthropods aia nā huaora a me nā minela e pono ai no ko lākou olakino.

ʻAe, inā paʻakikī ka loaʻa ʻana o ka meaʻai, a i ʻole ua pau, a laila hiki iā ʻoe ke hānai iā ia me nā ʻāpana moa a i ʻole nā ​​ʻiʻo ʻē aʻe, nā limu, nā enuhe a me nā ʻupena like ʻole. Ma muli o ka maʻemaʻe o ke kaiapuni, pono e hōʻoia i ka waiho ʻole ʻana o ka meaʻai i loko o ka aquarium no nā lā ʻelua.
