Analysis of Ultrasonic Tracking Records of Adult Sockeye Salmon Migration in Babine Lake

Migratory pathways of adult sockeye salmon (Oncorhynchus nerka) on their way to the spawning grounds in Babine Lake were monitored by ultrasonic tracking techniques in 1969 and 1970. This report presents procedures and computer programs used for processing the tracking data. It also contains instructions for coding meteorological and other environmental data for further analysis. Investigators employing ultrasonic tracking techniques to study movements of aquatic animals use a variety of methods to record and analyze their data. Standardizing the collecting and processing methods of such data makes comparisons between different studies easier and more meaningful. We hope that the recording and analysis procedures discussed in this report can be a base for such standardization.
