About Na Khayat Subdistrict
Na Khayat (ตำบลนาขยาด) is a subdistrict in Khuan Khanun District, Phatthalung. The local authority's contact information places its office in village 10, while Ban Ngok Nam is documented as a community associated with preserved fish production.
A Department of Science Service library abstract describes the development of pla duk ra, a salted and fermented catfish product, at Ban Ngok Nam. Its origins lie in household food preservation and later community production. This is a local food tradition, rather than a claim that every village or shop offers the same product.
Contact a producer or community group before arranging a food-related visit or purchase. Confirm the precise village address and any demonstration arrangements. Public service enquiries should go to the relevant authority; the tambon coordinate is not the council office or a food shop.
