I konei, e hiahia ana ahau ki te whakauru atu i ētahi momo whakaongaonga whāngai ika e whakamahia whānuitia ana, pērā i ngā waikawa amino, te betaine hcl, te dimethyl-β-propiothetin hydrobromide (DMPT), me ētahi atu.

Hei tāpiri i ngā kai i roto i te wai, ka kukume mai ēnei matū i ngā momo ika ki te whāngai, ka whakatairanga i te tipu tere me te hauora, ā, ka piki ake te hua o ngā mahi hī ika.

He mea nui te mahi a ēnei tāpiringa, hei mea whakaohooho whāngai nui i roto i te mahi ahuwhenua ika. Ehara i te mea miharo, i whakaurua mai ēnei ki te mahi hī ika i te tīmatanga, ā, kua kitea he tino whai hua.
I te tīmatanga, i tangohia mai te DMPT, he paura mā, mai i te rimu moana. I roto i ngā momo whakaoho kai maha, he tino mīharo tōna pānga kukume. Ahakoa ngā kōhatu i rumakina ki te DMPT, ka taea e ngā ika te ngau i a rātou, ā, ka tapaina ko "kōhatu ngau ika." E whakaatu ana tēnei i tōna whai huatanga ki te kukume i te whānuitanga o ngā momo ika.

I te whanaketanga tere o te hangarau me te mahi ahuwhenua ika, ngā tikanga hangai mōKua whakapai tonu te DMPTKua puta mai ētahi momo e pā ana, he rerekē te ingoa me te hanganga, ā, kua piki haere te kaha o ngā pānga kukume. Ahakoa tēnei, e kiia tonutia ana rātou koDMPT, ahakoa he nui tonu ngā utu mō ngā mea hangai.

I roto i te mahi ahuwhenua ika, he iti noa iho te rahinga e whakamahia ana, he iti iho i te 1% o te kai, ā, he maha ngā wā ka honoa ki ētahi atu mea whakaohooho kai wai. Hei tētahi o ngā mea kukume tino ngaro i roto i te hī ika, kāore au i te tino mārama me pēhea e whakaohooho ai i ngā io o ngā ika kia akiaki tonu i te whāngai, engari kāore tēnei e whakaiti i taku mōhio ki te tūranga kore e taea te whakakorekore o tēnei matū i roto i te hī ika.

1. Ahakoa te momo DMPT, ka pā tōna pānga kukume i te tau katoa, puta noa i ngā rohe, e kapi ana i te nuinga o ngā momo ika wai māori, kāore he okotahi.
2. He tino whai hua i te mutunga o te kōanga, i te raumati katoa, me te tīmatanga o te ngahuru—ngā wā he tino teitei te pāmahana. Ka taea e ia te ārai i ngā āhuatanga pēnei i te pāmahana teitei, te iti o te hāora rewa, me te iti o te pēhanga o te rangi, e akiaki ana i ngā ika kia kaha te kai me te auau.
3. Ka taea te whakamahi tahi me ētahi atu mea kukume pēnei i ngā waikawa amino, ngā huaora, ngā huka, me te betaine hei whakarei ake i ngā pānga. Heoi, kaua e whakaranua ki te waipiro, ki ngā mea kakara rānei.
4. I te hanga mōunu, whakarewahia ki te wai parakore. Whakamahia anake, whakaranua rānei ki ngā mea kukume kua whakahuatia i te tohu 3, kātahi ka tāpirihia ki te mōunu. He pai mō te whakamahi me ngā mōunu kakara taiao.
5. Inenga: Mō te whakarite mōunu,me 1–3% o te ōwehenga o te witi. Whakapaia kia 1–2 ngā rā i mua atu, ā, rongoatia ki roto i te pouaka whakamātao. Ina whakaranua te mōunu, tāpirihia te 0.5–1%. Mō te whakamakuku i te mōunu hī ika, whakaranua kia tata ki te 0.2%.
6. Ka taea e te nui rawa o te whakamahinga te arahi ki ngā "wāhi mate" (ka nui rawa te ika, ka mutu te kai), he mea nui tēnei kia mōhiotia. I tetahi atu taha, ki te iti rawa, kāore pea e tutuki te hua e hiahiatia ana.

I te mea he āhuatanga o waho pērā i te āhua o te wai, te rohe, te āhuarangi, me te huringa o te wā, me noho ngāwari tonu ngā kaihao ika ki tā rātou whakamahinga. He mea nui kia kaua e whakaaro ko te whai i tēnei mea whakaoho anake ka eke ki te angitu o te hī ika. Ahakoa ko ngā āhuatanga o te ika te mea e whakatau ana i te hopunga, ko te pūkenga o te kaihao ika tonu te mea tino nui. Ehara i te mea ko te whāngai i ngā mea whakaoho te mea nui i roto i te hī ika—ka taea noa e rātou te whakapai ake i tētahi āhuatanga kua pai kē, kāore e huri i tētahi āhuatanga kino.
