ʻO ka daphnia hānau ma ka home

ʻO Daphnia nā crustacean e hoʻohana ākea ʻia i nā aquaristics, ʻoiai he meaʻai āpau ia no nā poʻe he nui o ka aquarium. Noho kēia mau crustacean i nā kūlana kūlohelohe i nā loko iʻa, akā hiki nō hoʻi ka hānau ʻana daphnia ma ka home. ʻO ka hapanui pinepine, ma ka home, hānai ʻia kēia ʻano crayfish ma ke ʻano he daphnia moina, a pili pono ia i ka hānau ʻana ma ka home e kūkākūkā hou ʻia ai.

E kamaʻilio e pili ana i ka hānai ʻana i ka daphnia ma ka home, pono e hoʻomākaukau mua ʻaʻole wale nā ​​ipu, akā ʻike nō hoʻi pehea e hānai ai i kēia crustacea microscopic a pehea e hana ai i nā kūlana kūpono.

Ipu

ʻO nā ipu me ka nui o 15-20 liters kūpono no ka ulu ʻana ma ka home. I ke kaʻina o ke koho ʻana i nā ipu, pono e noʻonoʻo ʻia nā ʻōlelo aʻoaʻo aʻe:

• Koho i kahi mea e hoʻokuʻu ʻole i nā kemika weliweli i loko o ka wai, e like me polypropylene. Kūpono, paipai ʻia e koho i kahi ipu aniani.
• inā hoʻohana ʻia nā ipu hao, ʻaʻole pono e hana ʻia i ke kila kila.
• inā ʻoe i koho i kahi aquarium kīʻaha maʻamau, ʻo kahi e pili ana me ka ea e like ka nui me ka hiki, no ka mea pono kēia no ka hoʻololi kinoea kūlohelohe a me ka hāʻawi ʻana o ka oxygen i daphnia.
• inā, i ke kaʻina hana o ka mālama ʻana i ka daphnia, mālama ʻia kahi ipu me ia i waho ma lalo o ka lā ikaika a i ʻole i kahi hale me nā pono uila, pono e koho ʻia ka nui o ka ipu ma kahi o 40 liters.

Nā kūlana o ke kino no ka mālama ʻana i daphnia

1. Kāpena ʻOiai he crustacea wai hou kēia, a laila, no laila, pono e hou ka wai i loko o kahi waihona i hana ʻia no lākou.
2. Oxygen. ʻAe hoʻomanawanui ʻo Daphnia crayfish i nā pae o ka oxygen i loko o ka wai, hiki ke hoʻololi ʻia mai ka ʻole a i ka māʻona. I kēia hihia, pono e ʻōlelo ʻia ʻaʻole ʻae ʻo daphnia i ka aeration wai o ka wai i loko o kahi waihona i hana ʻia, me ka hoʻokuʻu ʻia o nā huʻa liʻiliʻi, a me ka aeration lohi me ka hoʻokuʻu ʻia o nā huʻa nui, e hana i ka hua ma luna o ka wai.
3. I nā mea o ka pae o ka amonia i ka wai a me ka pae o ka wai, ʻo nā mea hōʻike ʻoi loa ka acidity o ka wai i ka laulā o 6.5-9.5 a me nā hōʻailona ʻoi loa 7.2 - 8.5
4. Ke kamaʻilio nei e pili ana i ke ʻano mahana wela maikaʻi loa, ka daphnia, hiki ke ʻike ʻia nā kiʻi ma luna a i ʻole i nā puke kūikawā, hiki ke noho i ka wai me kahi ākea mahana. ʻO ka mahana optimum no ka hānau ʻana ma ke kaha o 18-22 kekelē.

He aha e hānai ai

Inā hānai ʻoe i ka daphnia ma ka home, he nīnau maoli kā nā poʻe hoʻomaka - pehea e hānai ai i kēia mau crustacea. ʻAi maoli ʻo Daphnia moina i ka bacteria a me ka hū, a me nā microplants.

Hiki ke kiʻi ʻia nā bacteria mai nā ʻili maiʻa ʻelua, ʻōpala meaʻai, a me nā lepo o ka maʻamau, i pulu mua ʻia i ka wai a hoʻokomo ʻia no kekahi mau lā. Ma ke ʻano he kānāwai, hoʻomaka ka wai e lilo i ao, e hōʻike ana i ka hoʻonui a me ka ulu ʻana o nā koʻohune - e hoʻokō ʻia ka hopena i 6-7 mau lā.

Hoʻohui ʻia ia ʻano wai hānai turbid i kahi pahu o 450 ml no 20 liters, i kēlā me kēia lā he 5-6.

ʻO ka hū kekahi meaʻai momona. I kēia hihia, e hana ka hū maloʻo maloʻo maʻalahi a maʻalahi hoʻi i kūʻai ʻia i nā pūʻolo. Lawe ʻia lākou i ka helu o 28 gram ma 20 liters o ka wai - ʻo kēia ka maʻamau o kēlā me kēia lā no daphnia, ʻoiai e hoʻonui ana i nā limu microscopic, ka mea e pale ai i ka hoʻohaunaele o ka wai a lawelawe ma ke ʻano he nutrient hou no nā crustacea liʻiliʻi.

ʻO ka maikaʻi o ka hū ma ke ʻano he mea hānai ka maʻalahi o ka hoʻohana ʻana a me ke kūʻai ʻana, akā ʻoi aku ka waiwai ma mua o ka limu. Pono e hoʻolako ʻia nā limu mikroscopic i daphnia i nā nui he nui - hiki iā ʻoe iho ke ʻike ma nā wahi kahi e ulu ai nā limu i nā loko a me nā loko iʻa, ʻoi aku ka nui o ka daphnia i ka nui.

ʻO ka maikaʻi o ka hoʻohana ʻana i ka limu i loko o ka meaʻai ko lākou maʻalahi o ka hoʻohana - ʻoi aku ka maikaʻi e koho i nā limu o ka ʻohana Scendesmus, a me chlorella, e ulu nei i nā helu he nui i kahi aquarium lako hou. Lawa wale nō e huki i ka wai mai ia aquarium, kau i kahi mehana ma lalo o nā kukuna o ka lā - e ulu ikaika ka limu, e lawelawe ana i ka wā e hiki mai ana ma ke ʻano he meaʻai no daphnia.

I ka wai i loaʻa ka daphnia, hiki iā ʻoe ke hoʻohui i ka wai beet a i ʻole kāpī, kāloti - 1 tsp. no 5 liters o ka leo - ʻaʻole kēia wale nō e hoʻoliʻiliʻi i ka papaʻai o nā crustacea, akā lawelawe pū ʻia me ke kumuwaiwai o lākou. Hāʻawi ka hoʻohui o ka manure wai i nā kaha liʻiliʻi i kahi hopena maikaʻi loa, akā ʻaʻole koi ka poʻe aquarist ʻike i ka hoʻohui ʻana i ka waiū a i ʻole ka infusion hay - kū lākou i ka ulu a me ka hana hou ʻana o daphnia.

ʻAeration

E kamaʻilio e pili ana i ka hānau ʻana o daphnia, e nīnau paha nā aquarist novice - pono paha ka ea i ka wā e ulu ana a mahi i nā crustacea? ʻ saylelo nā loea loea he makemake ia, keu hoʻi i ka ulu ʻana ʻo Daphnia moin. Hoʻonui ia i ka wai me ka oxygen, paipai i ka hoʻomohala ʻana o ka phytoplankton a pale i ka hoʻokumu ʻia ʻana o kahi kiʻi ʻoniʻoni ma luna o ka wai. ʻO ka mea nui ʻo ka aeration pono ke ʻano waena, no ka mea e hoʻopilikia kahi kahe o ka ea iā lākou, a e hōʻiliʻili kahi kahawai me nā huʻa liʻiliʻi ma lalo o ka pūpū o ka crustacean a hāpai iā lākou i luna.

Pehea e hoʻomaikaʻi ai i ka hana i ka hana hoʻomohala?

Maʻalahi kēia hana a ʻo kahi mea hoʻomaka pū me ka haʻohaʻo e ka nīnau pehea e hānai ai i nā crustacea hiki ke mālama iā ia. I kēia hihia, e noʻonoʻo i kekahi mau ʻōlelo kikoʻī kikoʻī:

1. ʻO ka aeration maikaʻi, me ke kahe o ka lewa a ʻaʻohe liʻiliʻi a nui paha nā huʻa. ʻO kēia ke kūlana mua no ka hoʻonui ʻana i ka hana i ke kaʻina hana o ka hana hou ʻana i nā muliwai crustacea. I kēia mea, paipai nā aquarist ʻike i ka hoʻohana ʻana i kahi kānana ea-ea i loko o kahi pahu me daphnia, i hoʻohana ʻia i nā pā me nā pā.
2. Mālama i ka maʻemaʻe o ka wahi a me ka hoʻololi mau ʻana i ka wai o ka wai - inā nui ka nui o ka aquarium, nona nā crustacea, pono ia e pani i ka ¾ o ka hoʻohui wai.
3. ʻO ka ʻohi mau ʻana o ka moʻomeheu e kōkua i ka mālama mau ʻana i ka hana hou a me ka ulu ʻana o daphnia i ka pae kūpono.
4. Hiki i nā hola ke ao 24 mau hola ke hoʻonui i ka helu ulu a me ka hana kope hou. ʻOiaʻiʻo, ʻaʻole kēia kahi mea e pono ai, akā hoʻonui nui ia i ka ulu a me ka hana hou ʻana o kēia muliwai, microscopic crustacean. I kēia hihia, ʻo ka lōʻihi palena iki o nā hola ao no lākou ma kahi o 18 mau hola.
5. ʻO ke aupuni a me ka pākēneka o ka pani ʻana i ka wai i loko o nā pahu i loaʻa ka daphnia - i kēia ʻano, pono e noʻonoʻo he aha ka hānai e hoʻohana ai, pehea ka nui o kahi waihona i hana ʻia a me ka nui o daphnia i loko. Akā i kekahi hihia, pono e hoʻomaʻemaʻe i ka wai mai nā huahana metabolic o nā microorganism a me nā toxins.

E like me kāu e ʻike ai, ʻo ka daphnia hānau, ka mea lawelawe ʻaʻole wale ia he meaʻai momona a maʻalahi hoʻi no kāu iho a me ka iʻa, akā he manaʻo maikaʻi nō hoʻi ia no ka ʻoihana home, maʻalahi ma ka home.
