Juvenile salmon traveling northwestward to the Pacific Ocean from the Strait of Georgia migrate through and take residence in both Johnstone and Queen Charlotte Straits. Johnstone Strait is a narrow and deep passage that is tidally mixed daily, resulting in a nearly isothermal water column, surface to the bottom (approximately 250 m). The trophic gauntlet hypothesis (McKinnell, Curchitser, Groot, Kaeriyama, & Trudel, ) suggest...

We examined 1454 juvenile C hinook salmon, O ncorhynchus tshawytscha ( W albaum), captured in nearshore waters off the coasts of Washington and O regon (USA) from 1999 to 2004 for infection by R enibacterium salmoninarum , N anophyetus salmincola C hapin and skin metacercariae. The prevalence and intensities for each of these infections were established for both yearling and subyearling C hinook salmon. Two metrics of salmon g...

This study employed a combination of otolith microchemistry to indicate the recent habitat use, and plasma concentrations of the hormone insulin‐like growth factor 1 ( IGF1 ) as an index of recent growth rate, to demonstrate differences in growth and habitat use by Dolly Varden Salvelinus malma occupying both freshwater and estuarine habitats in south‐west Alaska. Extensive sampling in all habitats revealed that fish had highe...

In two year classes of Willamette River spring chinook salmon, reared at the Willamette Hatchery, and two groups of Yakima River spring chinook salmon, one sampled from the Yakima River and the other reared in a hatchery, fish which had relatively high growth rates in the summer–autumn period smolted in the autumn as measured by increases in gill Na + K + AT Pase activity. In contrast, groups with relatively low growth rate di...
