Tracking natal origins of salmon using isotopes, otoliths, and landscape geology
The inability to identify natal origins (i.e., individual rivers and hatcheries) of adult Pacific salmon in the ocean has impeded our understanding of their ocean ecology and the management ofExpand

Marine survival of steelhead (Oncorhynchus mykiss) enhanced by a seasonally closed estuary
To investigate the role that estuaries play in the survival of steelhead, Oncorhynchus mykiss, we compared juve- nile size at ocean entry with back-calculated measures of size at ocean entry forExpand

Steelhead Growth in a Small Central California Watershed: Upstream and Estuarine Rearing Patterns
We monitored growth and life history pathways of juvenile steelhead Oncorhynchus mykiss and compared growth rates between the upper watershed and estuary in Scott Creek, a typical California coastalExpand

Physiological ecology of juvenile chinook salmon (Oncorhynchus tshawytscha) at the southern end of their distribution, the San Francisco Estuary and Gulf of the Farallones, California*
Juvenile chinook salmon, Oncorhynchus tshawytscha, from natal streams in California’s Central Valley demonstrated little estuarine depen­ dency but grew rapidly once in coastal waters. We collectedExpand

The effects of surgically implanted acoustic transmitters on laboratory growth, survival and tag retention in hatchery yearling Chinook salmon
Telemetry has proven an effective means for studying the movement of fishes, however, biases associated with tagged animals requires careful scrutiny if accurate conclusions are to be made from fieldExpand

Should I Stay or Should I Go? The Influence of Genetic Origin on Emigration Behavior and Physiology of Resident and Anadromous Juvenile Oncorhynchus mykiss
Abstract We investigated the interaction among genetically identified origin, behavioral tendency to emigrate, and Na+, K+-ATPase enzyme activity in recently diverged subpopulations of residentExpand

Energy dynamics and growth of Chinook salmon (Oncorhynchus tshawytscha) from the Central Valley of California during the estuarine phase and first ocean year
The greatest rates of energy accumulation and growth in subyearling Chinook salmon (Oncorhynchus tshawytscha) occurred during the first month following ocean entry, supporting the importance of thisExpand

Growth, survival, and tag retention of steelhead trout (Oncorhynchus mykiss) and its application to survival estimates
Steelhead trout, Oncorhynchus mykiss, are known to expel acoustic tags which can negatively bias population survival estimates. Tag burden may also affect the development and behavior of smolts,Expand

Managed Metapopulations: Do Salmon Hatchery ‘Sources’ Lead to In-River ‘Sinks’ in Conservation?
Maintaining viable populations of salmon in the wild is a primary goal for many conservation and recovery programs. The frequency and extent of connectivity among natal sources defines theExpand

Chinook salmon outmigration survival in wet and dry years in California's Sacramento River
Outmigration survival of acoustic-tagged, hatchery-origin, late-fall-run Chinook salmon (Oncorhynchus tshawytscha) smolts from the Sacramento River was estimated for 5 years (2007–2011) using aExpand
