Standard Operating Procedure for Diagnosing and Addressing Predator Detections in Salmon Telemetry Data

Description / purpose

Tag predation is a complicating factor in juvenile salmon telemetry studies that can bias results, delay timely reporting, and prevent effective data synthesis. This project addresses the problem by (1) characterizing predatory fish movement patterns from existing telemetry data in the Delta; (2) developing a standard operating procedure for diagnosing and handling detections of predated tags in salmon telemetry studies; and (3) implementing the recommendations in a software package in Program R that includes code, a “library” of expected predator behaviors, and example vignettes. The R package will be freely available for download at www.cbr.washington.edu.
