Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Weitkamp, Laurie A. (American Fisheries Society, 2008-05)

One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter thei ...
Marine distributions of chinook salmon from the West Coast of North America determined by coded wire tag recoveries

Weitkamp, Laurie A. (American Fisheries Society, 2010-01)

The coded wire tag (CWT) database contains detailed information on millions of Pacific salmon Oncorhynchus spp. released from hatcheries or smolt traps and recovered in the north Pacific Ocean and its tributaries. I use ...
Ontogenetic shifts in diets of juvenile and subadult coho and chinook salmon in coastal marine waters: important for marine survival?

Daly, Elizabeth A.; Brodeur, Richard D.; Weitkamp, Laurie A. (American Fisheries Society, 2009-11)

Successfully shifting to a more piscivorous diet may be an important factor in the growth and survival of juvenile coho salmon Oncorhynchus kisutch and Chinook salmon O. tshawytscha during their first summer in the north ...
Seasonal and interannual variation in juvenile salmonids and associated fish assemblage in open waters of the lower Columbia River estuary

Weitkamp, Laurie A.; Bentley, Paul J.; Litz, Marisa N. C. (National Marine Fisheries Service, NOAA, Scientific Publications Office, 2012-10)

The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this de ...
Spatial and trophic overlap of marked and unmarked Columbia River Basin spring Chinook salmon during early marine residence with implications for competition between hatchery and naturally produced fish

Daly, Elizabeth A.; Brodeur, Richard D.; Fisher, Joseph P.; Weitkamp, Laurie A.; Teel, David J.; Beckman, Brian R. (Springer, 2011-06-04)

Ecological interactions between natural and hatchery juvenile salmon during their early marine residence, a time of high mortality, have received little attention. These interactions may negatively influence survival ...
