Includes bibliographical references (pages 7-10). "Juvenile chinook salmon (Oncorhynchus tschawytscha) were collected from upper Yukon River tributaries in 1987 and 1988. Scale interpretations indicated that the majority of juveniles (92.2%) were in their first summer of life (age 0.0) and their fork length ranged from 47 to 96 mm. The remaining juveniles were in their second summer of life (age 1.0) and their fork length ranged from 65 to 105 mm. Juveniles collected in May 1988 had no identifiable freshwater annulus. If an annulus was forming on the scales of these fish then it was completed sometime after May or it became more distinct with the addition of spring or plus growth during the downstream migration. Variability in fork length among populations of juvenile chinook salmon with the same number of circuli suggested that circuli were not deposited at consistent length increments among populations"--Abstract, page iii.
