Emerging Baselines to Estimate the Migration Patterns of Dolly Varden Charr Nearshore and on the High-seas

摘要

Dolly Varden (Salvelinus malma) is a dominant freshwater species in arctic and subarctic eastern Russia, Alaska, and western Canada and an important food source for indigenous people in these regions. Anadromous Dolly Varden are distributed throughout Alaska and occupy a wide variety of habitats, from coastal streams in the southeast panhandle to rivers draining the North Slope. Anadromous Dolly Varden show highly complex migration patterns. They typically feed in marine waters in the summer, home to spawn in their natal streams, and overwinter in natal and non-natal freshwater lakes and rivers in mixed aggregations.
