Abstract
New graphical techniques are applied to study the migration of chinook salmon (Onchorynchus tshawytscha). The techniques are based on plots of median recapture dates, log of the number of recaptures, and drawings of fish on grid maps. Under certain assumptions, the graphs can be used to generate hypotheses about the direction of movement of the salmon at different ages and brood years. The techniques developed are shown to adhere to the established principles of graphical design and could be extended for other similar studies.
