Te kikorangi metilēna mō ngā ika i ngā taika: ngā whakamahinga, ngā herenga, me ngā whakatau mō te taika
He whakamahinga motuhake tō te kikorangi metilēna i te tiaki taika ika, otirā mō ngā hua ika me ētahi raruraru kei te mata o te tinana. Ko tōna tika mō tō mahere maimoatanga ka whakawhirinaki ki ngā mea e toru: te raruraru o te ika, ngā matū kei roto tonu i te pātara, me te wāhi e whakahaeretia ai te maimoatanga.
He rerekē te taiao maimoatanga o tētahi ipu tahanga e pupuri ana i ngā hua ika i tērā o tētahi taika he tipu, he tini momo ika hoki kei roto. Kāore e taea te whakawhiti noa i ngā tohutohu mō tētahi ki tērā atu nā te mea he wai, he ika hoki kei roto i ngā mea e rua. Me tīmata ki te raruraru me te pūnaha i mua i te tatau i te rahinga.
Te kaupapa o tētahi hua mō te taika ika
E whakamārama ana ngā kōrero a Kordon mō tōna hua kikorangi metilēna i tētahi hua wai 2.303% hei whakahaere i te hekaheka i runga i ngā hua ika me ngā pokenga hekaheka kei te mata o te tinana, me ētahi whakamahinga tuarua mō ētahi rauropi pūtau-tahi o waho. E kōrerotia ana hoki tōna āwhina i ngā take paihana nitiraiti, paihana cyanide rānei kua mōhiotia. Ka whakakore te kaiwhakanao i ngā pokenga huakita, ngā noke papatahi pirinoa, te Oodinium, me ngā mate hekaheka kino ake i ngā whakamahinga e tohua ana. He hua tēnei mō ngā ika whakapaipai, ehara i te rongoā mō ngā ika hei kai, i te hua rānei hei kai mā te tangata.
He mea nui aua herenga. He kāwai te “rongoā ika”, ehara i te tātaritanga. Ki te kī te kaitiaki he hekaheka ngā tupu mā katoa, tērā pea ka kōwhiria e ia he hua kāore tōna whakamahinga i whakaritea e hāngai ki te pūtake o te raruraru. E kōrero ana te aratohu mō te kikorangi metilēna mō ngā hua ika mō taua whakamahinga motuhake; e whakamārama ana ngā whakataurite maimoatanga taika ika i te take kāore ētahi atu matū e taea te whakakapi noa i a rātou anō.
Tirohia te kounga wai i mua i te whakamārama i ngā tohu
Ki te māuiui ētahi ika, tuhia ko ēhea momo e pāngia ana, āhea i tīmata ai te rerekētanga, me ngā panonitanga nō nā tata nei: te tāpiri ika, te whāngai, te whakakapi wai, ngā taputapu, te maimoatanga rānei. Kaua e whakatau i tētahi ingoa mate mai i aua kitenga i mua i te tirotiro i te taiao.
E tūtohu ana te aratohu a UF/IFAS mō te whakahaere hauora ika kia tirohia te kounga wai i te tuatahi ina āhua māuiui ngā ika. Ko ngā whakamātautau iti rawa hei tirotiro i tētahi pānga mate, ko te hāora kua rewa ki te wai, te haukinia, te nitiraiti, me te pH. Ko te kapo hau i te mata o te wai, te mirimiri ki ngā mea o roto, te ngoikore rānei he tohu raruraru, engari kāore e tautuhi i te pūtake. Ki te puta he tuwhenua, ki te mau tonu te uaua ki te hā, ki te mate tonu rānei ngā ika, me wawe te aromatawai a tētahi rata kararehe wai, a tētahi mātanga hauora ika rānei.
Ahakoa he mārama te āhua o te wai i te taika, kei roto tonu pea te haukinia. E whakamārama ana a UF/IFAS kāore he tae, he haunga rānei o te haukinia i ngā kukū e kino ai ngā ika, ā, me mōhio ki te paemahana me te pH hei whakamārama i te haukinia tapeke. Kāore te waikano e taea te whakakapi i aua inenga. Hei tauira, ki te mutu te mahi a tētahi tātari, kāore te whakatau mō tētahi rongoā e whakatika i te ngaronga o te āheinga tukatuka para.
He raruraru rerekē anō te nitiraiti, te nitireiti, te haukinia, me te iti o te hāora kua rewa ki te wai. Ka wehewehea e te kōrero mō te kikorangi metilēna me te paihana nitiraiti i ngā ika te tukanga e pā ana ki te toto i te whakatikatika i te wai tonu.
He rākau whakatau mō te taika ika
Whāia ngā rārangi i te raupapa. Ko te tikanga o te “kati”, kei te ngaro ētahi kōrero e hiahiatia ana hei whakatau maimoatanga, ehara i te mea me waiho ngā ika kia kore ai e tiakina.
| Whakatau | Mēnā āe | Mēnā kāo, kāore rānei e mōhiotia |
|---|---|---|
| 1. Kua aromatawaitia te kounga wai me ngā rahunga taputapu me whakatika wawe? | Tuhia ngā hua, ka haere tonu. | Whakamātauria te wai, ka whakatika i te raruraru tiaki o nāianei; rapua he āwhina wawe mēnā e kino haere ana te āhua o ngā ika. |
| 2. E hāngai ana te raruraru kua tautuhia ki ngā whakamahinga o tēnei hua mō ngā taika ika? | Tirohia ngā momo ika me te wāhanga o te huringa ora e whāia ana. | Kāti te kōwhiri rongoā, ka rapu tātaritanga. |
| 3. Ka taea te pānui i te hua ake, te kukū o te matū hohe, me ngā tohutohu? | Tuhia te hanganga o te hua me te tikanga maimoatanga motuhake. | Kaua e whakakapi ki tētahi rahinga rongoā nō tētahi atu pātara, nō tētahi tohutaka ipurangi rānei. |
| 4. Ka taea e te taika e whakaarohia ana te whakatutuki ngā here hototahitanga o te tapanga? | Whakamaheretia te tuku hau ki te wai, te aroturuki, me te whakahaere taputapu. | Aromatawaitia tētahi pūnaha maimoatanga motuhake, tētahi atu huarahi tika rānei, me tētahi mātanga. |
| 5. E mōhiotia ana te rōrahi tūturu o te wai maimoatanga ki ngā waeine e whakamahia ana e te tapanga? | Whakamahia taua rōrahi me ngā tohutohu ake o te hua. | Inea i mua i te whakarite i te wai maimoatanga. |
| 6. Kua whakaritea he mahere mātakitaki me te whakaoti? | Tuhia ngā panonitanga, ka whai i te maimoatanga kua tohua. | Whakamāramatia te roanga, te tango i te matū, te aroturuki, me te rapu āwhina anō i mua i te tīmata. |
Ka hono tēnei rākau whakatau i ngā whakatau e toru e whāia motuhaketia ana i te nuinga o te wā: te kōwhiri maimoatanga, te whakarite i tōna kukū, me te kōwhiri i te taiao e pā ai te matū ki ngā ika. Ahakoa ka tutuki te tirotiro kukū, kāore tērā e whakakapi i tētahi tirotiro tātaritanga kāore i tutuki.
Ehara te kukū o te pātara i te kukū o te taika ika
E whakaatu ana te ōrau i te pātara i te wairewa pūtake. E whakaatu ana ngā tohutohu maimoatanga i te rahinga o taua wairewa ka tāpirihia ki tētahi rahinga wai kua tohua, i raro i ngā āhuatanga kua tohua. He rahinga rerekē ēnei.
Hei tauira tatau māmā, whakaarohia ētahi wairewa pūtake wai e rua, he mea whakapae noa, kua tapaina ki te 1% me te 2%, e whakamahi ana i te pūtake kukū kotahi. Mēnā he ōrite ngā rōrahi kua inea, kei roto i te wairewa 2% te rua whakareatanga o te waikano. Kāore taua whakataurite e whakaatu ko tēhea kukū e tika ana mā tētahi ika. E whakaatu ana i te take kāore tētahi tatau pata kua taunga ki a koe e tika hei tohutohu mō ngā hua katoa.
Tuhia tahitia te ingoa hua, te kukū, te rōrahi wai kua inea, te waeine rōrahi, me te tikanga e whakaarohia ana. He kawa rerekē te rumaki poto me te tuku kia pā te matū mō tētahi wā roa ake; kaua e whakakotahi i te kukū o tētahi me te roanga o tērā atu. E kōrero ana te aratohu mō te whakamārama i ngā tohutohu rahinga kikorangi metilēna mō ngā taika ika mō ēnei rerekētanga.
He wāhanga te taika nō te maimoatanga
Ka whakatūpato a Kordon kia kaua e whakamahia i ngā pūnaha e whakawhirinaki ana ki te tātari koiora, ka whakatūpato hoki mō te whakararu i te tipu o ngā otaota, ā, ka tohu ka tangohia te matū e te waro whakahohe, ka ngongo hoki ki ngā rawa kōputaputa. Ka aro āna tohutohu ki ngā taiao maimoatanga tahanga, ā, ka whakatūpato ka tae pūmau pea te silicone o te taika ika. Arotakehia ngā tohutohu o te pātara o nāianei me te aratohu hototahitanga mō te taika me ngā kararehe o roto.
He take whaitake tō te tiaki i te tātari koiora. Ka tukatuka ngā rauropi huri haukinia i te haukinia me te nitiraiti; ka whakaputa para tonu ngā ika i te wā e tiakina ana. Ki te whakararu tētahi maimoatanga i taua tukanga, ka hua ake he raruraru tuarua hei whakahaere. Mā tētahi taika motuhake e tiaki te pūnaha whakaaturanga kei pāngia e te matū, engari kāore e whakarato aunoa i te kounga wai e tika ana mō te ika e maimoatia ana.
E tūtohu ana ngā aratohu a UF/IFAS mō ngā matū i ngā pūnaha wai hurihuri kia wehea ngā ika kua pāngia mō te maimoatanga ina taea, ā, e whakamārama ana ka whakawhirinaki ngā pānga matū ki te pānga atu ki ngā ika me ngā āhuatanga o te pūnaha. Me wehe ngā taputapu maimoatanga, me whakamahere hoki te aroturuki, te whakahaere paemahana, me te tuku hau ki te wai. Kaua e whakapae ko ngā tohutohu mō ngā ika anake e whakapūmau ana i te hototahitanga ki ngā kōeke, ngā ngata, ngā wheo, ki ia momo ika rānei.
Me whai take te whakamahi auau
Ehara te wai kawe kikorangi i te taunakitanga ka whai painga ngā ika hou katoa i te rumaki ārai mate. I ngā whakamātau i pūrongotia e te Taiwhanga Ahumoana Pārūrū o te Whare Wānanga o Florida, kāore te kikorangi metilēna i whakamahia hei rumaki ārai mate i whakapai ake i te āhua, i te whanonga rānei o ngā ika i inea. I tētahi whakamātau kawe motuhake me ngā ika hiku-hoari velvet, i kitea he pai ake te āhua i taua wā tonu me te kikorangi metilēna, engari i muri i te kotahi wiki he ōrite te āhua o ngā rōpū maimoatanga. He rerekē ēnei wā me ēnei tikanga o te pānga matū, me ngā kitenga hoki; ehara i te tūtohutanga mō ngā kawe ika katoa.
Mō ngā ika kātahi anō ka tae mai, whakaritea he mahere taratahi me te mātakitaki. E whakatakoto ana ngā aratohu a UF/IFAS mō te tiaki haepapa i ngā taika ika i te taratahi, te tātari tika, te kai tōtika, me te kounga wai hei wāhanga o te ārai mate auau. Me whakautu te rongoā i tētahi hiahia kua tautuhia i roto i taua mahere.
I mua i te whakamahi i te kikorangi metilēna, me āhei koe ki te whakahua i te raruraru e whakatikaina ana, te hua ake e whakamahia ana, me te huarahi e aroturukitia ai te taiao maimoatanga. Ki te ngaro tētahi o aua whakautu, whakatauria i mua i te whakakikorangi i te wai.
