ʻO ka ʻauʻau wai: he aha ke ʻano o ka daphnia a pehea e ulu ai

He aha ke ʻano o Daphnia: kiʻi

ʻO ka wehewehe ʻana o ka nalo

inoa: Daphnia
ʻŌlelo Lākni: ʻO Daphnia

Papa: nā inike - Pepelu
pūʻulu: Nā crustacean wāwae wāwae - Anomopoda

	Nā wahi noho:	nā waihona wai kūpaʻa
	Kaha punaewele:	nā limu, nā mea plankton
	Ka luku:	lilo nā ʻōpala i nā iʻa like ʻole

ʻO Daphnia ma lalo o ka microscope.

No ka ʻano crustacean planktonic ka liʻiliʻi crustacean. Pili ka nui i ke ʻano. Hiki ke ʻokoʻa mai ka 2 a 6 mm. Ma muli o ka liʻiliʻi o ke kino, paʻakikī ke ʻike i ke ʻano. E kōkua ka microscope i kēia.

He oval ke kino. Aia ma nā ʻaoʻao ʻelua kahi kiʻi kūikawā. Hōʻike ia i ka pale ʻana i nā ʻōpū o loko. ʻO nā mea honi ka antennae ma ke poʻo. Me ko lākou kōkua, hiki i nā ʻauʻau ke hoʻokuke, ʻauʻau, lele.

Aia nā wāwae ma ka umauma. Hele nā ​​algae a me nā bacteria ma waena o lākou. Hiki i nā ʻauʻau ke hanu ma nā ʻeke gill. Loaʻa i nā ʻeke gill nā bristles e hana ma ke ʻano he kānana.

Aia ma luna o 150 mau ʻano cladocerans. Ma ko mākou latitu hiki iā ʻoe ke ʻike:

• magnu - ka mea nui loa;
• pulexa - he awelika ka nui;
• koʻu - liʻiliʻi.

Aia mau ka ai mea kanu i ka opu. Loaʻa iā ia nā mea trace pono e pono ai ka poʻe noho o ka aquarium.

wahi

ʻO ka wahi noho maʻamau, ʻo ia nā loko paʻa. Hiki iā lākou ke noho i loko o ka loko a me ka loko hohonu. ʻAʻole ʻokoʻa ʻo Antarctica anuanu.

ʻO kekahi o nā kūlana koʻikoʻi ka hiki ʻana o ka wai maʻemaʻe me ka liʻiliʻi o ka lepo.

Hāʻawi ka wai lepo i ka kānana ʻāina a me ka noho ʻana o nā algae i loko o ka ʻōpū.

Daphnia: kānana kūlohelohe.

Ke alakaʻi nei kēia i ka pipili. Ma ka loaʻa ʻana o nā crustaceans i loko o ka wai, akaka ka maʻemaʻe o ka loko, loko, kahawai. Hāʻawi ka wai lepo i ka kānana ʻāina a me ka noho ʻana o nā algae i loko o ka ʻōpū. Ke alakaʻi nei kēia i ka pipili.

Noho kekahi mau ʻano ma lalo, e ʻai ana i nā ʻāpana make o nā mea kanu a me nā koena o nā invertebrates. I kekahi manawa hiki ke ʻike ʻia i loko o nā puddles a me nā lua me ka wai. I ka mālamalama mālamalama, hūnā hohonu nā crustaceans. Loaʻa pinepine ʻia kēia mau ʻōpala ma loko a me nā loko.

ʻAi ʻai ʻo Daphnia

ʻO Daphnia i ka wai.

ʻO ka meaʻai nui ka mea hū a me ka bacteria blue-green. Hiki ke ʻike ʻia ka nui o ka unicellular i loko o kahi waihona pua, kahi e noho ai nā iʻa liʻiliʻi. ʻAi pū lākou i nā ciliates a me nā detritus.

Hiki ke kānana wai ma muli o nā wāwae pectoral. Ma hope o kēia, komo ka meaʻai i ka auwai o ka ʻōpū o ka ʻōpū, a laila i loko o ka esophagus. Hāʻawi ka ʻāʻī salivary a me ka huna ʻana o nā lehelehe luna i ka hoʻopili ʻana o nā meaʻai i loko o kahi puʻupuʻu.

ʻO ka filtration rate o nā pākeke mai 1 a 10 ml i ka lā. Pili ke kaumaha o ke kino i ka nui o ka meaʻai. Hiki i ka magna makua ke ʻai i 600% o kona kaumaha kino.

Po'ai ola

ʻAʻole pono ka hiki ke hana hou i ka fertilization. Loaʻa i nā wahine kahi keʻena hānai. Mālama ʻia e ka lihi o ka pūpū. ʻO nā kūlana maikaʻi e makemake i ka waiho ʻana o 50 a 100 mau hua manu ʻole. I loko o nā lua, ulu ka ulu ʻana o nā wahine. A laila, puka nā wāhine i ka lua.

mau enemi maoli

ʻO nā ʻenemi ka mea ʻai i nā holoholona liʻiliʻi. Aia nā ʻenemi kūlohelohe:

Nā kūlana hānai

Hiki iā ʻoe ke hānai i ka daphnia ma ka home. He mau ʻōlelo aʻoaʻo:

• he ʻōmaʻomaʻo a ʻulaʻula paha ka wai;
• ʻAʻole ʻae ʻia nā ʻelele ʻē aʻe o ka wai e komo. Eia kekahi laʻana, nā Cyclopes;
• ʻO ka meaʻai nui he letus maloʻo a he hua waina paha;
• e hānai me ka hū a ka mea palaoa, kahi i kāwili mua ʻia a kānana ʻia e ka gauze;
• ua lawa ia e huki wai mai loko mai o ka waihona i loko o 50 kanaka. Hoʻohui ʻia ka meaʻai kuke i kēia wai;
• e hoʻohana i kahi ipu aniani, akā e waiho i kahi mamao mai ka lā;
• mālama i nā mahana mai 20 a 24 degere Celsius;
• hoʻomaʻemaʻe a hoʻololi i ka wai e pale ai i ka hōʻiliʻili ʻana o ka lepo a i ʻole ka lepo ma lalo;
• hoʻohana i ka wai i loaʻa ʻole ka chlorine a me nā haumia kemika.

Nā pōmaikaʻi o Daphnia

Loaʻa i ka Daphnia ka nui o ka protein. Hoʻoikaika nā amino acids i ka ulu wikiwiki a me ka ulu ʻana. Hoʻohui pinepine ʻia lākou i ka meaʻai iʻa maloʻo. I kēia hihia, ʻo ka hapalua o ka nui ka protein.

hopena

He meaʻai waiwai ʻo Daphnia no nā iʻa aquarium, i kūʻai ʻia ma nā hale kūʻai. Mahalo i ka meaʻai ola, hoʻemi ʻia ka morbidity a maʻalahi ka hoʻololi ʻana i nā kūlana hou. Eia naʻe, inā makemakeʻia, hiki iāʻoe ke hānai iāʻoe iho.
