Otolith Trace Element Chemistry as an Indicator of Anadromy in Yukon River Drainage Coregonine Fishes
Abstract Eight coregonine species have been documented in the Yukon River drainage. They include inconnu Stenodus leucichthys , broad whitefish Coregonus nasus , humpback whitefish C. pidschian , Alaska whitefish C. nelsonii , least cisco C. sardinella , Bering cisco C. laurettae , round whitefish P...
