Te kikorangi metilīni mō ngā hua ika me te whakamahi i ngā whare pao
He mahi motuhake tā te kikorangi metilīni i ētahi tikanga tiaki hua ika whakarākei: ko te whakahaere i te tipu harore i te wā whakatupu kukune. Ehara i te mea e tika ana ia wairewa kikorangi mō ia huinga hua. He rerekē ngā kararehe, ngā pūnaha wai, ngā whāinga, me ngā whakaritenga maimoatanga o te tāke whakawhānau discus, te rīhi rangahau zebrafish, me te whare pao taraute.
Tīmata mā te tautuhi ko tēhea o aua horopaki e pā ana ki a koe. Kātahi ka tirohia te hua ake me te kawa tiaki hua ika. Ko te pātai whai take, mehemea e hāngai ana te whakapānga kua whakaarotia ki tēnei huinga hua, kaua ko te pātai mehemea e whakamahia whānuitia ana te kikorangi metilīni e ngā kaiwhakatipu ika.
Ngā mea ka taea e te maimoatanga hua ika
E tautuhi ana ngā tohutohu mō te hua Kordon Methylene Blue i te ārai, i te maimoa rānei i te harore i runga i ngā hua ika hei whakamahinga i whakaritea. E whakaahua ana aua tohutohu i tētahi hanganga wairewa ā-wai 2.303% motuhake. He tohutohu ēnei nā te kaihanga mō taua hua, ehara i te whakaaetanga mō te whakaputa ika hei kai, i te kī taurangi rānei ka ōrite ngā putanga mō ia momo ika.
Kotahi noa te wāhanga o te whakatupu kukune e whakatikaina ana e te whakahaere harore. Kāore e taea e tēnei te whakakikī i tētahi hua kāore anō kia whakakikīngia, te whakaora rānei i tētahi kukune kua mate. Nō reira, he rerekē te maha o ngā hua i whakaputaina me te maha o ngā kukune e ora ana hei tīmatanga mō te aromatawai i tētahi maimoatanga.
Ka taea hoki te raruraru te horapa. E whakaahua ana ngā aratohu whakatupu kukune taraute a Hendrix Genetics i te tipu o Saprolegnia i runga i ngā hua mate, me tōna toro atu ki ngā hua hauora. E whakanui ana ā rātou aratohu tiaki ika i te pupuri i te rere wai e tika ana, me te tango i ngā mea mate kia iti rawa te whakararuraru. Ki te tāpirihia he matū, engari ka waiho tonu ngā hua e pirau ana, ka noho tonu tētahi wāhanga o te raruraru.
Ki te kore e mārama ngā hua, ki te puta rānei he tipu āhua miro, tuhia ko tēhea huringa i puta tuatahi. Kāore te āhua anake e whakaū i te take i kore ai ngā kukune e ora. Ki te mate haere ngā kukune i ngā wā maha, me arotake te whakakikīnga, ngā āhuatanga whakatupu kukune, te whāwhā, me te tūponotanga o tētahi mate whakapoke.
Whakahāngaitia te momo ika ki tōna horopaki
E wehe ana tēnei ripanga i tētahi whakamahinga mō ngā ika whakarākei kua tohua ki te tapanga, i tētahi tikanga rangahau, me tētahi whakatau whakaputa ika e herea ana e ngā ture. He āwhina tēnei mō te kōwhiri, ehara i te ripanga rahinga maimoatanga mō ngā momo ika katoa.
| Momo ika, rōpū hua rānei | Horopaki whakatupu kukune | Ngā mea e tautoko ana i te whakatau mō te kikorangi metilīni | Te here matua hei whakatau |
|---|---|---|---|
| Ngā hua ika whakarākei | He ipu whakawhānau motuhake mā te kaiwhakatipu runaruna | He hua mō te puna ika, me ngā tohutohu mārama mō te whakahaere harore i runga i ngā hua ika | Whakaūngia te hanganga o te hua, te wā whakapānga, te rōrahi wai tūturu, me tōna tika mō taua momo ika. |
| Discus, Symphysodon spp. | Ngā hua e piri ana ki tētahi koeko, papa kōhatu rānei, me ngā mātua kei reira | Ngā tohutohu whānui mō tētahi hua mō ngā ika whakarākei, me tētahi mahere whakawhānau e hāngai ana ki taua momo ika | Nā te tiaki hua a ngā mātua me te whāngai torongū ā muri ake, he whakatau motuhake te tango i ngā hua. |
| Zebrafish, Danio rerio | He wairewa whakatupu kukune mō te rangahau, he tukunga kukune rānei | He kawa nō te whare rangahau me ngā taunakitanga mō tōna kāwai ika me tōna wāhanga whanaketanga | Kāore te whakamahinga i te taiwhanga e whakaū i te whakapai ake i te paonga i ngā horopaki katoa. |
| Hāmana, taraute, ētahi atu ika whai pakihau hei kai rānei | Te whakatupu kukune i tētahi whare pao arumoni | Te whakaaetanga o nāianei mō taua rohe ture me te tapanga o te hua ake kua whakaaetia | Kāore tētahi tapanga kikorangi metilīni mō ngā ika whakarākei e whakamana i tēnei whakamahinga. |
Ko te “whare pao” he whakaahuatanga o tētahi wāhi mahi, ehara i te kāwai ture kotahi. Ka whai rūma whakatupu kukune te pakihi e whakawhānau ana i ngā discus whakarākei me tētahi e whakaputa ana i ngā taraute hei kai. He mea nui te whakamahinga whakamutunga o ngā kararehe, me tō rātou momo anō hoki. Ka whakamārama whānui ake te aratohu mō te kikorangi metilīni i te ahumoana me ngā ika hei kai i taua rerekētanga.
Me whakatau ko wai hei tiaki i ngā hua discus
Ka piri ngā hua discus ki tētahi mata. E ai ki ngā aratohu whakatipu discus a te Whare Wānanga o Florida, ka tiaki ngā mātua i ngā hua, ka kōwhiuwhiu hoki kia rere ai te wai whai hāora ki runga i aua hua. Whai muri i te paonga, ka kai ngā torongū kauhoe noa i te hūpē o ngā mātua.
Nā ēnei āhuatanga ka rerekē te pātai ā-mahi. Mā te nuku i tētahi koeko ki tētahi ipu maimoatanga motuhake ka whakawhitia hoki te kawenga mō te neke o te wai, ā, me whai mahere te kaiwhakatipu mō ngā torongū. Kāore te kōwhiri rongoā anake e whakarite i aua mea.
I mua i te nuku i tētahi huinga hua, tuhia mehemea mā ngā mātua e whakatipu, mā te tangata rānei. Mō te whakatipu mā ngā mātua, whakaarohia ngā ika pakeke me te pūnaha whakawhānau katoa i te aromatawai i tētahi hua. Mō te whakatipu mā te tangata, tohua me pēhea te whakatupu i ngā kukune i roto i ngā hua, me pēhea hoki te whāngai i ngā punua ika. Kaua e whakapae ko tētahi o aua mahere te tikanga o te tohutohu kia maimoatia ngā hua.
Kāore ngā puna kōrero i arotakengia i konei e whakaū i tētahi whakapānga kikorangi metilīni tino pai mō te discus ake. Kaua tētahi tapanga whānui mō ngā puna ika e whakaaturia hei whakataurite whakahaere i ngā pāpātanga pao o te discus.
He whai kōrero te whakamahinga rangahau, engari kei te horopaki tōna tikanga
E whakamārama ana ngā pātai auau a te Zebrafish International Resource Center he kikorangi metilīni kei roto i tō rātou wairewa tuku kukune hei whakaiti i te tipu moroiti ki te mate ngā kukune i te wā tuku. He tikanga tēnei kua tuhia e taua whare, mō tētahi kaupapa motuhake. Ehara tēnei i te taunakitanga ka pai ake ia whakatipu kukune mā te whakamahi i te waikano.
I whakamātauhia e tētahi rangahau i te tau 2020 nā Peneyra me ōna hoa ngā whakakotahitanga patu moroiti ki ngā kukune zebrafish AB me casper i te 6 me te 24 hāora i muri i te whakakikīnga. I aromatawai ngā kairangahau i te oranga, te paonga, me ngā hē o te hanga tinana i te rima rā i muri i te whakakikīnga. He rerekē ngā pānga o te kikorangi metilīni ki te oranga me te paonga i ngā āhuatanga rerekē; ko ngā putanga pai rawa i kitea i te nuinga o te wā i ētahi whakakotahitanga maimoatanga, whai muri ko te tiaki me te kore kikorangi metilīni.
He rangahau tēnei mō ngā whakakotahitanga matū e pā ana ki te patu moroiti i te mata mā te hipokōraiti konutai. Kāore tēnei e whakaū he kino tonu te kikorangi metilīni, e hāngai rānei aua kitenga ki ngā hua discus. Heoi, e whakaū ana tēnei i te take me aromatawai te taiwhanga i te raupapa katoa me te wāhanga whanaketanga, kaua e whakaaro he wāhanga iti noa te waikano o te wairewa kāore ōna pānga nui.
Pānuihia ngā tohutohu mō ngā hua ika, kaua ngā tohutohu rumaki ika
E whakarato ana te whārangi a Kordon i ngā tukanga motuhake mō te maimoatanga hua ika me ngā rumakitanga poto o ngā ika. Kāore e taea te whakawhiti noa i aua whakapānga. E whakatūpato ana hoki kia kaua tō rātou hua e whakamahia i ngā pūnaha whakahuri wai whai tātari koiora, nā te mea ka whakararu i ngā huakita whakaputa pākawa; ka tango te waro whakahohe i te waikano. Tirohia te hototahitanga ki ngā tātari, ngā tipu, me ngā tāke i mua i te tuku i te hua ki tētahi pūnaha whakawhānau tūhonohono.
Whakatauritea ēnei mea e whā ki ngā tohutohu o nāianei kei te pounamu:
- Te tuakiri o te hua: tuhia te kaihanga, te hanganga, te kukū, me te whakamahinga i whakaritea.
- Te horopaki maimoatanga: wehewehea te ipu whakatupu kukune i roto i ngā hua, te pati poto, me te tāke katoa. E whakamārama ana te whakataurite o ngā pati ika me ngā maimoatanga tāke i te take he mea nui taua rerekētanga.
- Te whakapānga: tautuhia te rahinga kua tohua, te rōrahi wai kua inea, te roanga, me te wāhi mutu. Kaua e whakatau i te rahinga mā te kaha o te tae kikorangi.
- Te mātakitaki: tuhia te maha o ngā hua i te tīmatanga, ngā taunakitanga o te whanaketanga, ngā matenga, te maha i pao, me te oranga o ngā punua ika i muri mai.
Ehara te kaha pupuri wai kua tapaina mō tētahi tāke i te rōrahi wai tūturu i ngā wā katoa. Waihoki, kāore e taea te tārua ngā tohutohu e whakaatu ana i tētahi rōrahi o tētahi wairewa pūtake ki tētahi pounamu he rerekē tōna kukū. Whakamāramatia ēnei rangirua i mua i te maimoatanga.
He tīmatanga kē e hiahiatia ana mō ngā whare pao ika hei kai
I Te Hononga o Amerika, kei roto i te rārangi rongoā ahumoana kua whakaaetia e te FDA ētahi hua formalini kua whakaingoatia mō ngā hua ika whai pakihau, me te 35% PEROX-AID mō ngā matenga e pā ana ki te saprolegniasis i ngā hua ika whai pakihau e whakatipuria ana ki te wai māori. Kāore te kikorangi metilīni i te rārangi hei rongoā ahumoana kua whakaaetia. Ka tino kī hoki a Kordon kia kaua tō rātou hua e whakamahia hei rongoā mō ngā ika hei kai.
E whakamārama ana te reta a te FDA ki ngā ngaio ahumoana ehara te ōrite o te matū hohe ki tērā o tētahi hua kua whakaaetia i te mea ka whakaaetia hoki tētahi atu hua. Nō reira, kāore hoki te kī “whakamahia kētia te perōkai hauwai” e rawaka hei tohutohu whakaputa ika: me hāngai te hua, te take whakamahinga, me ngā tohutohu tapanga.
He kitenga ēnei mō Amerika, i tirohia i Mahuru 2026. Mō tētahi atu rohe ture, me whai te whare pao i te whakaaetanga ā-rohe o nāianei me tētahi aromatawai nā te ngaio hauora kararehe wai i mua i te kōwhiri maimoatanga. Tuhia taua whakatau ki te kawa mō te huinga hua. Kāore tētahi kōrero mō te angitu o te whakawhānau ika whakarākei e whakaū i te tika ā-ture, ā-koiora rānei o tētahi maimoatanga mō ngā ika hei kai.
