Hoʻomaopopo nā ipo iʻa iʻa i ka nui o kā lākou ʻano, akā ʻaʻole naʻe. Akā ʻike maopopo nā aquarist āpau i ka crustacean liʻiliʻi e hele i kā lākou mau holoholona no ka meaʻai - gammarus.
ʻO Gammarus helehelena
Pili ka ʻohana gammarids i ke ʻano o ka crayfish kiʻekiʻe. Pili ʻo Gammarus i ke kauoha o amphipods a ʻoi aku ma mua o 200 mau ʻano. ʻO ka inoa maʻamau no amphipods i ka poʻe he mormysh, a hui pū ia ma mua o 4500 mau ʻano.
He mau mea liʻiliʻi kēia, ma kahi o 1 knm ka lōʻihi. Kiko ʻia ko lākou kino i loko o ka arc, pale ʻia e ka uhi chitinous, nona nā ʻāpana he 14. Pili ke kala o ka gammarus i ka meaʻai e ʻai ai.
Ke ʻōmaʻomaʻo ke kala o nā crustacean e ʻai ana i nā mea kanu, aia nā mea ʻeleʻele a me ka melemele, nā ʻano ʻokoʻa e noho i Lake Baikal, a ʻaʻohe waihoʻoluʻu o nā ʻano kai hohonu. Aia nā lālā o ka hihiʻo - ʻelua mau maka hui, a me nā lālā o ka pā - ʻelua mau antennae ma ke poʻo. Kuhi ʻia kahi mau kohola i mua a lōʻihi hoʻi, nānā ka lua i hope.
He ʻelua mau wāwae o Gammarus, a he kuleana pono ko kēlā me kēia paʻa. Loaʻa i nā wāwae pectoral ke kani i hoʻohana ʻia no ka hanu ʻana. Pale lākou i nā pā lahilahi akā paʻa. Ke neʻe mau nei nā lālā e hoʻolako i kahi komo o ka wai hou a me ka oxygen. Eia kekahi ma nā paʻa mua ʻelua he mau māiʻuʻu, e pono ai e hopu i ka mea pio a i ka wā o ke kōkua kope e paʻa paʻa i ka wahine.
Hoʻohana ʻia ʻekolu mau kapuaʻi wāwae ma ka ʻōpū no ka ʻauʻau ʻana a hāʻawi ʻia me ka hulu. ʻO nā hui hope ʻekolu e kuhikuhi i hope a he ʻano like me ka lau, ʻo lākou a me ka huelo o ka crustaceans e kipaku a neʻe i mua i mua.
Uhi ʻia hoʻi lākou i ka hulu. Me kēia mau mea hana i hoʻonohonoho pono ai ʻo gammarus i kāna kuhikuhi ponoʻī. Hoʻokomo pū ʻia ke kino o nā wahine me kahi keʻena brood kūikawā, aia ma ka umauma.
ʻO Gammarus wahi noho
He ākea loa ka nohona o Gammarus - noho ia i ka hapa nui o ka Hemisphere ʻĀkau, pili pū me Kina, Iapana, a me nā mokupuni he nui. Ma nā panalāʻau o ko mākou ʻāina, loaʻa nā ʻano laha like ʻole ma Lake Baikal. ʻIke ʻia nā ʻano ʻano like ʻole a puni ka honua.
Noho ʻo Gammarus i ka wai hou, akā nui nā ʻano i noho i nā wai paʻa. Kūpono nā kahawai, nā loko, nā loko iā lākou. Koho i nā waihona wai maʻemaʻe, ma ke kū ʻana o gammarus i loko o ka wai, hiki iā ʻoe ke hoʻoholo i ke kiʻekiʻe o ka oxygen i loko o ka waihona wai.
Aloha i ke kau anuanu, akā hiki ke ola i nā mahana a + 25 C⁰. I ka wela, ʻike pinepine ʻia ia ma lalo, ma lalo o nā pōhaku anuanu, ma waena o nā limu, nā lāʻau drift, kahi e liʻiliʻi ai ke kukui. Makemake ʻo ia e ʻauʻau i ke kahakai, i nā wai pāpaʻu, makemake i nā wahi malu.
I ka hoʻoilo, piʻi aʻe ia mai lalo a pili i ka hau, kū kēia no ka mea ʻaʻole lawa ka oxygen o ka amphipod ma lalo. No ka hānai ʻana, ua poho ia i lalo a aia i waena o nā mānoanoa.
ʻO ka nohona Gammarus
ʻEleu loa ʻo Gammarus, holo mau. No nā wai ʻauʻau ka holoholo ʻana, akā pili pū nā wāwae wāwae. I nā kino wai pāpaʻu, kokoke i ke kahakai, ʻauʻau nā crustacean ma ko lākou mau ʻaoʻao, akā i ka hohonu hohonu e pae ai lākou a ʻauʻau me ko lākou mau kua i luna. Piʻi ka neʻe ʻana, kūlou mau ke kino a kū ʻole hoʻi. Inā he kākoʻo paʻa ma lalo o kou mau wāwae, a laila hiki iā Gammarus ke lele i waho o ka wai.
ʻO ka koi mau no ka oxygen hou e koi i ka Gammarus e neʻe wikiwiki i kona mau wāwae mua i mea e hoʻoulu ai i ka wai i nā gills. I nā wahine, i ka wā o ke kū ʻana o nā ʻūlū, holoi ʻia ka paʻa i ka lumi brood i kēia ala.
ʻO koʻu ola āpau crustacean gammarus ulu, ke hoʻololi nei i ka chitinous crustinous i lilo i mea liʻiliʻi no kahi mea hou. I ka hoʻoilo, kū ka molt 1.5-2 manawa i ka mahina, a i ke kauwela, hoʻokahi manawa i ka pule.
Loaʻa nā wahine ma hope o ka hiku o ka molt i nā pā ma ka umauma, kahi lumi brood. ʻO ke ʻano o kēia keʻena o kahi moku, hoʻohui i ka ʻōpū me kahi pae lattice, a ma waho o ke āpau ma waena o nā pā i uhi ʻia me nā bristles lahilahi. No laila, nui nā lua i loko o ke keena, mahalo i ka wai mau e kahe ana i nā hua.
ʻO ka meaʻai maikaʻi ʻo Gammarus
ʻO ka meaʻai a Gammarus ka mea kanu a me nā meaʻai holoholona. ʻO kēia nā ʻāpana palupalu o nā mea kanu, ʻo ka hapa pinepine o ka palaho o nā lau i hāʻule, ka mauʻu. Pili ka mea like i ka meaʻai holoholona - makemake i nā koena i make.
Lawe kēia i kekahi mau pōmaikaʻi i ka waihona wai - hoʻomaʻemaʻe iā gammarus iā ia i nā koena ʻino ʻino. ʻAi lākou i ka plankton. Hiki iā lākou ke ʻai i nā ilo liʻiliʻi, akā i ka manawa like hoʻouka lākou iā lākou i kahi ʻohana.
Hōʻiliʻili lākou no ka hānai ʻana inā loaʻa iā lākou kahi mea nui me kahi pāʻina awakea nui. Inā loaʻa i ka crustacean iʻa make i loko o ka ʻupena lawaiʻa, e ʻūlū maʻalahi lākou i ka mea kaua, me ka mea pio.
Hoʻohua a me ke ola o gammarus
Kū ka hana kope o Gammarus i ka puna a me ke kauwela. I ka hema, hoʻokele nā crustacea e ulu i kekahi mau paʻa, ma ke kūkulu ʻākau, hoʻokahi wale nō i ka waena o ke kauwela. I loko o kēia wā, loaʻa ke kāne i ka wahine, pili iā ia i hope a kōkua i ka mea i koho ʻia e kāpae i nā "lole" kahiko.
Ke hoʻopau ka wahine, hūnā ke kāne i ka sperm, kahi āna i hamo ai me kāna mau wāwae i ka lumi brood. Ma hope o kēlā, ua hoʻokō ʻo ia i nā hana a kahi makuakāne a haʻalele i ka makuahine e hiki mai ana. Hoʻomoe ka wahine i kāna mau hua i kāna keʻena. Nui a pouli lākou.
Ua piʻi ka helu i 30 ʻāpana. Inā mahana ka wai, a laila lawe nā hua i 2-3 mau wiki e pā. Inā maikaʻi ke loko, a laila holo ka "hāpai keiki" i 1.5 mau mahina. ʻAʻole e holo i waho nā larva i pāpale ʻia, noho lākou i ka lumi brood a hiki i ka molt mua, a laila haʻalele lākou.
Me kēlā me kēia molt e hiki mai ana, hoʻolōʻihi ʻia nā antennas o ka pā. Hiki iā Gammarus i hāhā i ka wā puna ke loaʻa i kā lākou keiki ponoʻī i ka hāʻule. A ola nā crustaceans ma kahi o hoʻokahi makahiki.
ʻO ke kumukūʻai o gammarus i hānai
ʻO ka hapanui pinepine crustacean gammarus hoʻohana ʻia me hope no ka iʻa aquarium. Hānai ʻia ka mea like gammarus a me nā kuhukukū, mauʻu... He meaʻai momona loa ia me ka protein hapa. Loaʻa iā ia ka nui o carotene, e hāʻawi ana i nā kala ʻōlinolino i ka iʻa iʻa.
ʻOiaʻiʻo, hiki iā ʻoe ke kūʻai iā ia ma nā hale kūʻai o nā holoholona, kumu kūʻai no gammarus ʻoluʻolu a pili i ka mea hana hope a me ka leo. No laila nā ʻeke o 15 gram i kēlā me kēia kumukūʻai ma kahi o 25 rubles, a i ke kūʻai ʻana gammarus maloʻo ma ke kaupaona, hiki iā ʻoe ke ʻike i ke kumukūʻai a me 400 rubles i kēlā me kēia kilogram.
Ke hopu nei i ka gammarus ʻaʻole paʻakikī, no laila inā loaʻa i kāu wahi nā loko iʻa kūpono, hiki iā ʻoe ke hoʻolako i kāu mau mōkai aquarium me ka meaʻai iā ʻoe iho. Ua lawa ia e waiho i kahi pūʻā mauʻu a mauʻu mauʻu paha ma lalo o ka waihona wai, a ma hope o kekahi mau hola e kiʻi aku ia me kahi mormy paʻa i laila, kahi e kokoke ana i ka ʻaina awakea.
Hiki iā ʻoe ke kūkulu i kahi ʻupena ma kahi lāʻau lōʻihi, a lawe iā lākou mai lalo o nā pūʻolo limu, a mai laila ʻoe e koho ai i nā crustaceans. Hiki iā ʻoe ke mālama i ka lawaiʻa i loko o ka wai kahi i hopu ʻia ai, hiki iā ʻoe ke wahī iā ia i kahi lole ʻūpū a waiho i kahi wahi anuanu. Akā inā nui ka mormysh a ʻaʻohe manawa o ka iʻa e ʻai ai, a laila ʻoi aku ka maikaʻi o ka hoʻomaloʻo ʻana a i ʻole paʻa manuahi no ka wā e hiki mai ana.
