Residence and growth of juvenile chum salmon (Oncorhynchus keta) in Netarts Bay, Oregon

Creator:: Wilson, Matthew T.
Abstract:: Estuarine residence and growth of juvenile chum salmon (Oncorhynchus keta) from Netarts Bay, Oregon were estimated from daily-formed growth increments of sagittal otoliths which are distinguishable from accretion patterns formed during freshwater residence. Estuarine residence time was inversely related to the average size at which juvenile chum salmon entered Netarts...
