The article presents some research approaches to the fairy-tale folklore of Bulgarians from the Republic of Moldova. According to the author, the fairy-tales texts of Bulgarians from the Republic of Moldova, their semantic, symbolic, and structural features should be researched as a local (regional) variant of Bulgarian folklore. Identification of ethnocultural markers in the fairy-tales of local Bulgarians on some different levels (such as on the subject, ethno-social and spiritual (church-religious) level) will allow to identify some peculiarities in the adaptation process of Bulgarians that migrated to a new ethnocultural zone, as well as to identify the level of preservation of basic ethnic mentality under the conditions of new “mental environment”. Thus, the study of regional ethnic culture is an interdisciplinary research, which allows discovering how localization in time and space affects ethnic culture, in general, and oral folk art, in particular.
