AVÀÇÂÛ̳

Project Description

In Arctic AVÀÇÂÛ̳, the Dolly Varden char is highly valued as a subsistence fish; however, little is known about several aspects of its oceanic dispersal, behavior, and life history. This multidisciplinary, collaborative project has revealed several previously undescribed facets of the biology and ecology of Dolly Varden, including rates of interdrainage exchange, as well as freshwater overwinter survival and marine summer survival. Of particularly note, while in the Arctic Ocean, Dolly Varden frequently occupy offshore waters up to several hundred kilometers from land, while largely remaining surface oriented. Such knowledge aids in understanding potential impacts of human activities such as hydrocarbon development, and environmental change in the Arctic.
