Juvenile salmonid survival studies planned for the Yakima Basin will require the release and recapture of large numbers of marked fish. Before these studies can be implemented, information is needed about potential recovery rates of marked fish at proposed sampling sites. The type of mark employed and the efficiency of the equipment used to capture and examine fish for marks must be evaluated since accurate survival estimates depend on their reliability. Recovery rates are expected to vary with species and life stage as well as environmental factors such as river flow and water temperature. The purpose of this study was to assess the mark-recovery capabilities of the Chandler facility and a mobile juvenile fish trap installed temporarily at West Richland, Washington near the mouth of the Yakima River
