Kua tūhuratia te whakakapinga wāhanga o te paraoa ika ki te paraoa pīni soya (SBM) hei huarahi tauwhiro me te huarahi ōhanga i roto i te maha o ngā momo ahumoana arumoni, tae atu ki te taraute āniwaniwa wai māori (Oncorhynchus mykissHeoi, he nui ngā saponin me ētahi atu āhuatanga ārai-kai kei roto i te pīni soya me ētahi atu rauemi tipu e whakaoho ana i te mate puku iti o te whekau pito tawhiti i roto i te nuinga o ēnei ika. Ko te āhuatanga o tēnei āhuatanga ko te pikinga o te urunga o te whekau, te mumura, me ngā āhuatanga rerekē o te āhua e arahi ana ki te hekenga o te whai huatanga o te kai me te ngoikore o te tipu.

I roto i ngā ika taraute āniwaniwa, tae atu ki te SBM neke atu i te 20% o te kai kua whakaatuhia ka puta te mate puku soya, ka whakatakoto i tētahi paepae ā-tinana ki te taumata ka taea te whakakapi ki tētahi kai ahuwhenua ika paerewa. Kua tirotirohia e ngā rangahau o mua ētahi tikanga hei whawhai i tēnei mate puku, tae atu ki te whakahaere i te microbiome puku, te tukatuka kai hei tango i ngā āhuatanga ārai-kai, me ngā tāpiringa antioxidant me probiotic. Ko tētahi huarahi kāore anō kia tūhuratia ko te whakaurunga o te trimethylamine oxide (TMAO) ki ngā whāngai ahuwhenua ika. Ko te TMAO he cytoprotectant whānui, kua kohia i roto i ngā momo maha hei pūmua me te whakaū membrane. I konei, ka whakamatautauria e mātou te kaha o te TMAO ki te whakarei ake i te pumau o ngā enterocyte me te pehi i te tohu HSP70 mumura, kia whawhai ai ki te mate puku i puta mai i te soya, ā, ka arahi ki te pikinga o te whai huatanga o te whāngai, te pupuri me te tipu o te ika taraute āniwaniwa wai māori. I tua atu, ka tirohia e mātou mēnā ka taea te whakamahi i ngā ika wairewa moana, he puna nui o te TMAO, hei huarahi whai hua ā-ōhanga mō te whakahaere i tēnei tāpiringa, kia taea ai te tono i runga i te tauine arumoni.

I whakatōngia ngā ika taraute āniwaniwa i whakatipuria (Troutlodge Inc.) ki te taumaha tīmatanga toharite o te 40 karamu me te n=15 mō ia tāke ki roto i ngā tāke maimoatanga toru. I whāngaihia ngā tāke ki tētahi o ngā kai e ono i whakaritea i runga i te pūtake matūkai ka taea te keri, e whakarato ana i te 40% o te pūmua ka taea te keri, te 15% o te ngako mata, me te tutuki i ngā kukū waikawa amino pai. Ko ngā kai i whakaurua ko te kai ika mana whakahaere 40 (% o te kai maroke), SBM 40, SBM 40 + TMAO 3 karamu kg^-1, SBM 40 + TMAO 10 karamu kg^-1, SBM 40 + TMAO 30 karamu kg^-1, me te SBM 40 + 10% wairewa ika. I whāngaihia ngā tāke i ngā wā e rua i te rā kia mākona rawa mō ngā wiki 12, ā, i whakahaerehia ngā tātaritanga paru, tata, histological me te ngota ngota.

Ka matapakihia ngā hua o tēnei rangahau me te whai huatanga o te whakauru i te TMAO kia taea ai te whakamahi nui ake i ngā hua pīni soya o Amerika ki ngā whāngai ika hāmana.
