Nunavik anadromous Arctic char life histories, behaviour and habitat use informed by both Inuit knowledge and western science: A year in Ungava Bay

Abstract

This study is a comprehensive documentation of anadromous Arctic char (Salvelinus alpinus) life history in Ungava Bay, Nunavik, Canada, through Inuit knowledge. Inuit experts shared their knowledge during semi-directed interviews and other occasions such as informal discussions and fieldwork. A contextualized synthesis of published western scientific literature is provided for the various life stages of Arctic char. The close year-round relationship Inuit have with Arctic char allows to set evidence of poorly described life history strategies in western literature and to reveal behaviours that, to the best of the authors’ knowledge, have not been documented so far. The connections and paralleling of Inuit knowledge and published studies about Arctic char informs western science with a more holistic understanding of Arctic char ecology. By bringing Inuit knowledge of Arctic char to the foreground, the present study highlights relevant research avenues for co-developed projects on Arctic char ecology.
