Hei kukume ika whai hua,dmpt (dimethyl - β - propionate thiamine)ka whakaoho tika i te hiahia rapu kai a te ika mā te whakatauira i ngā tohu kai e pai ana ki ngā ika i te taiao tūturu, ā, ka tino kukume mai ki ngā kura ika.

He rite tōna kaupapa mahi ki tētahi hakari kua whakaritea marietia, āDMPTHe rite ki tētahi pōwhiri e kore e kitea, e tuku puku ana i te whakamatautauranga e kore e taea te ātete ki te hī ika. Ina rewa ki te wai, ka tere, ka horapa ōrite, ka hanga he "papa aukume reka" me te wāhi hī ika hei pokapū, me te kukume hei radius. I roto i tēnei papa aukume, te āhua nei ka kumea ngā ika e tētahi kaha e kore e kitea, ka haere mai tētahi i muri i tētahi ki te tūhura i tēnei puna ohorere o te kai reka.

Ehara i te mea ka whakapūmau noa i te pānga hī ika o te mōunu paru, engari e whakaatu ana hoki i te ariā tiaki taiao o te noho tahi pai i waenga i te tangata me te taiao.
